Answer:

X=3

Step-by-step explanation:

Equation 1:

7×3=21

21+18=39

Equation 2:

10×3=30

30+9=39

If you replace x with 3 on both equations then you get 39 and if you get 39 on both equations that means it is equal.

Length: 16.5 in

Width: 6.6 in

Area: 108.9 in

Perimeter: 23.1 in

Step-by-step explanation:

Length: 7.5 • 2.2 = 16.5

Width: 3 • 2.2 = 6.6

Area: 16.5 • 6.6 = 108.9

Perimeter: 16.6 + 6.6 = 23.1

Answer:

20x - 21y + 14

Step-by-step explanation:

1/5(150x - 80y + 50 - 50x- 25y + 20)

Step 1 - Distribute

1/5 • 150x = 30x

1/5 • (-80y) = -16y

1/5 • 50 = 10

1/5 • (-50x) = -10x

1/5 • (-25y) = -5y

1/5 • 20 = 4

Step 2 - Combine Variables

30x - 10x = 20x

-16y - 5y = -21y

10 + 4 = 14

Step 3 - Arrange the Set of Numbers

20x - 21y + 14

This is the simplified expression, I know it is correct, I doubled checked on my expression calculator.

Answer:

i know its late but its -2.25 if you still need it

Step-by-step explanation:

just did it on edge

The rate of change for the relationship, given the data, is -2.25 gallon/min

Velocity is simply defined as the rate of change of displacement with time. Mathematically, it can be expressed as:

Velocity = displacement / time

With the above idea in mind, we can obtain the rate of change for the given relationship.

Column 1 i.e time (min) = 7, 8, 9, 10.

Column 2 i.e Water (gallons) = 38.5, 36.25, 34, 31.75.

Rate = Change in gallon/change in time

Rate = (36.25 - 38.5) / (8 -7)

Rate = -2.25 / 1

Rate of change = -2.25 gallon/min

Answer:

y = 2x + 10

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - [tex]\frac{1}{2}[/tex] x + 7 ← is in slope- intercept form

with slope m = - [tex]\frac{1}{2}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{1}{2} }[/tex] = 2 , thus

y = 2x + c ← is the partial equation

To find c substitute (- 2, 6) into the partial equation

6 = - 4 + c ⇒ c = 6 + 4 = 10

y = 2x + 10 ← equation of perpendicular line

Answer:

[tex]f(-1)=0[/tex]

Step-by-step explanation:

You are given the set [tex]f(x) = {(-1,0),(-2,2),(-3,-1)}[/tex].

All [tex]f(-1)[/tex] means is to find the y value when x is at -1.

Look at your first set of parenthesis. Your very first x term is -1, and it has a y output of 0.

There's your answer.

Answer:

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

Finding the y-intercept:

Look where the line touches the y-axis then that point is the y-intercept....in this case it's -3

Finding the Slope:

Look for a perfect point on the line then count how many places down you have to go and how many places right you have to go till you reach the next perfect point, this is called rise over run....so in this case it will go down 2 and right 1. So basically it's like this...

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

So that will simplify to -2

Finding the answer:

Once we plug everything in this formula...

[tex]y=mx+b[/tex]

We should get...

[tex]y=-2x-3[/tex]

Which is Choice D

Answer: y = -2x + 3.

Step-by-step explanation:

Answer:

x = 3.

Step-by-step explanation:

log4 (3x - 1) = log4 (x + 5)  Since they are both logs to the base 4:

3x - 1 = x + 5

2x = 6

x = 3.

On solving the logarithmic equation, we find that x = 3.

A logarithmic equation is an equation that involves the logarithm of an expression containing a variable.

[tex]log_{4}(3x-1) = log_{4}(x+5)\\\\3x-1 = x+5\\\\3x-x=5+1\\\\ 2x=6\\\\x=3[/tex]

Answer:

x=21

Step-by-step explanation:

supplementary angles add up to 180°

7x-3+2x-6=180

collect like terms

9x-9=180

add 9 to both sides

9x=189

divide both sides by 9

x=21

Answer:

see explanation

Step-by-step explanation:

The perimeter is the sum of the measures of the 3 sides.

Sum the sides and equate to 75, that is

2x - 9 + 3x + 4 + 2x + 3 = 75, that is

7x - 2 = 75 ( add 2 to both sides )

7x = 77 ( divide both sides by 7 )

x = 11

Thus

AB = 2x - 9 = 2(11) - 9 = 22 - 9 = 13 m

BC = 3x + 4 = 3(11) + 4 = 33 + 4 = 37 m

AC = 2x + 3 = 2(11) + 3 = 22 + 3 = 25 m

Answer:

x=11

Side lengths:

AB=13

AC=25

BC=37

Step-by-step explanation:

We can create an equation based off of the given information. Then, we simplify the equation to solve.

[tex](2x+3)+(3x+4)+(2x-9)=75\\(2x+3x)+(3+4)+(2x-9)=75\\(5x+7)+(2x-9)=75\\(5x+2x)+(7-9)=75\\7x-2=75\\7x=77\\x=11[/tex]

Then, we insert 11 for x, and evaluate the expressions for the side lengths.

[tex]AB=2x-9=2*11-9=22-9=13[/tex]

[tex]AC=2x+3=2*11+3=22+3=25[/tex]

[tex]BC=3x+4=3*11+4=33+4=37[/tex]

Finally, we check.

13+25+37 is 75, so this should be correct.
