PLEASE HELP ASAP!!!
A video screen is 16 in. by 12 in. tall. What is the width of the largest complete image possible for a photograph that is 2 in. wide by 3 in. tall?

Answer:

b) simplify the constant

c)isolate the variable by dividing the coefficient

Step-by-step explanation:

Answer:

Cannot be determined

Step-by-step explanation:

It can't be determined because AB=DE, BC=EF, and <ACB=<DFE not <DEF which makes the rule SSA which doesn't prove congruency.

Answer:

y-y1 = m(x-x1)

y - 2 = 3(x-1)

y=3x-3+2

y=3x-1

Step-by-step explanation:

first you type down point slope formula

then you plug in the information you have point (1,2) 1 is x1 and 2 is y1 m is 3 because m = slope

then you have to distribute the 3 to the x and the -1 and then isolate y

(how to isolate the y) you must do the opposite of -2 which is +2 whatever you do on one side you have to do to the other

then you combine like terms 3x is alone and -3 +2 equals -1

there is your answer hope that works.

I want to say it is 8,000

Step-by-step explanation:

go to 80 degrees and go up to the next point and that is on 8,000

Answer:

8,300

Step-by-step explanation:

If you continue the graph to 80 degrees, your average will end up at 8,300. You can tell because it will be above 8,000 but not close to 9,000 so it has to be 8,300.

Answer:

√3, and -√3

Step-by-step explanation:

to find the zeros or roots of the polinomial x²-3 make it equal to zero and solve for x

x²-3=0 add 3 to both sides to isolate x

x² = 3 squareroot both sides

√x²= √3

x= ±√3 are the two zeros

Answer:

6x + 7y +84

Step-by-step explanation:

The linear equation y = -(6/7) x + 12 in the standard form will be 6x + 7y - 84 = 0.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation in standard form is given as,

ax + by + c = 0

Where -a/b is the slope of the line and c/b is the y-intercept of the line.

The linear equation in slope-intercept form is given below.

y = -(6/7)x + 12

Convert the equation into a standard form. Then we have

y = -(6/7)x + 12

y = (-6x + 84) / 7

7y = - 6x + 84

6x + 7y - 84 = 0

The linear equation y = -(6/7) x + 12 in the standard form will be 6x + 7y - 84 = 0.

Answer:

angle A is congruent to angle R

Step-by-step explanation:

when it gets rotated counterclockwise around point X that is how the triangles end up matching up

Answer:

The answer is 1. ∠A ≅ ∠R

Step-by-step explaation:

Looking at the triangles when they're in their alphabetical order, ΔABC and ΔRST, since they are congruent, that means that if you were to pick an angle in one triangle, it would be equal to the angle in the same place of the other triangle. So if we were to take the first letter from ΔABC it'd be A, and the first letter in ΔRST is R, so that means angles ∠A and ∠R should be congruent.

The average rate of change is -12/5 for the interval [-2, 3] which is the negative average rate of change option (B) is correct.

It is defined as the change in values of a dependent variable with respect to the independent variables.

It is given that:

A function g(x) is shown in the table.

As we know the average rate of change of a function can be given:

The average rate of change = change in y values/change in x values

For the interval [1, 5]

The average rate of change = (2-0)/(5-1) = 2/4 = 1/2

For the interval [-2, 3]

The average rate of change = (-5-7)/(3+2) = -12/5

For the interval [-5, 0]

The average rate of change = (3-0)/(0+5) = 3/5

For the interval [-4, -1]

The average rate of change = (5-2)/(-1+4) = 3/3 = 1

Thus, the average rate of change is -12/5 for the interval [-2, 3] which is the negative average rate of change option (B) is correct.

Answer:

First, you need to find the unit rate by dividing 27/2. This equals 13.5. Then, multiply this by 1/2 to get 6.75 miles.

Answer:

[tex]r=6[/tex]

Step-by-step explanation:

Make an equation in point-slope form where:

Insert the known values:

[tex](-2_{x1},8_{y1})\\\\m=-\frac{1}{2} \\\\y-8=-\frac{1}{2} (x-(-2))\\\\y-8=-\frac{1}{2} (x+2)[/tex]

Use the distributive property:

[tex]-\frac{1}{2} (x+2)\\\\-\frac{1}{2}(x)-\frac{1}{2}(2)[/tex]

Simplify. Turn the 2 into a fraction by converting to the fraction [tex]\frac{2}{1}[/tex] , which is still equal to 2:

[tex]-\frac{1}{2}(2)\\\\-\frac{1}{2}*\frac{2}{1}[/tex]

Multiply across:

[tex]-\frac{1}{2}*\frac{2}{1} =-\frac{2}{2} =-1[/tex]

Re-insert into the equation:

[tex]y-8=-\frac{1}{2}x-1[/tex]

Solve for y. Add 8 to both sides (to isolate y using inverse operations):

[tex]y-8+8=-\frac{1}{2}x-1+8\\\\y=-\frac{1}{2}x+7[/tex]

Now insert the y value of the other point to find r (which will have the same value as x):

[tex](r_{x},4_{y})\\\\4=-\frac{1}{2}x+7[/tex]

Simplify the fraction by multiplying. Add 1 as the denominator for x:

[tex]-\frac{1}{2}*\frac{x}{1}[/tex]

Multiply across:

[tex]-\frac{1}{2}*\frac{x}{1}=-\frac{x}{2}[/tex]

Re-insert:

[tex]4=-\frac{x}{2} +7[/tex]

Subtract 7 from both sides (to isolate the variable using inverse operations):

[tex]4-7=-\frac{x}{2} +7-7\\\\-3=-\frac{x}{2}[/tex]

Multiply both sides by 2 (to undo the fraction using inverse operations):

[tex]2(-3)=2(-\frac{x}{2}) \\\\-6=-x[/tex]

Divide both sides by -1 (to make the variable positive, since two negatives make a positive):

[tex]\frac{-6}{-1} =\frac{-x}{-1} \\\\x=6[/tex]

Therefore, the value of r is 6.

it’s D

Step-by-step explanation:

A) 6 cm, 23 cm, 11 cm

B) 10 cm, 15 cm, 24 cm

C) 22 cm, 6 cm, 6 cm

D) 15 cm, 9 cm, 24 cm

Answer:

Step-by-step explanation:

1) x² + 3x + 1 = 0

a = 1    b = 3     c = 1

=> Δ = b² - 4ac = 9 - 4.1.1 = 5 > 0

so the quadratic equation have 2 solutions

=> x = [tex]\frac{-3+\sqrt{5} }{4}[/tex]

or  x = [tex]\frac{-3-\sqrt{5} }{4}[/tex]

2) x² + 4x - 8 = 0

a = 1    b' = 2    c = -8

Δ' = b'² - ac = 4 - 1.(-8) = 12 > 0

so the quadratic equation have 2 solutions

=> x = [tex]\frac{-2+\sqrt{12} }{1}=-2+\sqrt{12}[/tex]

or x = [tex]-2-\sqrt{12}[/tex]

3) x² - 5x -12 = 0

a = 1       b = -5    c = -12

Δ = b² - 4ac = 25 - 4.1.(-12) = 25 + 48 = 73 > 0

so the quadratic equation have 2 solutions

=> x = [tex]\frac{5+\sqrt{73} }{2}[/tex]

or x = [tex]\frac{5-\sqrt{73} }{2}[/tex]

Answer:

500-10x=250

x=how much the bird descended in a second

the bird will land on the ground in another 10 seconds.

Step-by-step explanation:

the bird will land on the ground in 10 seconds since it descended 250 ft in 10 seconds so that is 25 ft per second. then do 250/25 and you get 10. that is how you know the bird will land on the ground in 10 seconds.

Answer:

a) [tex]h(t)=500-25t[/tex]

b) [tex]t=20[/tex]

Step-by-step explanation:

a)

Let [tex]h[/tex] = height above ground

Let [tex]t[/tex] = time

Because the bird descended down to 250 feet in 10 seconds with a steady rate, that means it descends 25 feet per second.

∴   [tex]h(t) = 500-25t[/tex]

b)

To find the time it takes until the bird reaches the ground, [tex]h[/tex] must equal [tex]0[/tex]:

[tex]0=500-25t[/tex]

[tex]25t=500[/tex]

[tex]t=20[/tex]

∴ It takes 20 seconds for the bird to reach the ground.

Answer:

d

Step-by-step explanation:

Answer:

D. 104º

Step-by-step explanation:

So the inside of a triangle is equal to 180º and we already know two of the angles.

D = 47º

C = 57º

47 + 57 = 104

To solve angles A and B, we know that a straight line is 180º and we can figure out the angle of B because now all we have to do is subtract 104 from 180.

180 - 104 = 76, B = 76º

Because we know that a straight line is 180º and we already have the measure of angle B, all we have to do now is subtract 76 from 180.

180 - 76 = 104º

Answer:

Option B is correct option.

Step-by-step explanation:

We need to identify equations written in factored form.

Factored form: A factored form of expression is an expression broken down into a product of its factors.

In the given options A, C and D we don't have product of factors.

Only option B consists of product of factors.

So, Option B is correct option.

Answer:

  1 < 15 -2a < 7

Step-by-step explanation:

There are a couple of ways you can do this.

1) Put the minimum and maximum values of a into the expression to see what its corresponding values are:

  15-2a for a=4:

     15-2(4) = 7

  15-2a for a=7:

     15-2(7) = 1

Then ...

  1 < 15-2a < 7

__

2) Solve for a in terms of the value of 15-2a, then impose the limits on a.

  x = 15 -2a

  2a = 15 -x

  a = (15 -x)/2

Now, impose the given limits:

  4 < (15 -x)/2 < 7

  8 < 15 -x < 14 . . . multiply by 2

  -7 < -x < -1 . . . . . . subtract 15

  7 > x > 1 . . . . . . . . multiply by -1

  1 < 15-2a < 7 . . . . . use x=15-2a

_____

The vertical extent of the attached graph is the range of possible values of 15-2a. It goes from 1 to 7.
