Answer:

One such equation is y = -5x.

Step-by-step explanation:

Let's figure out the equation of the graph.

We see two points (1, -1) and (0, 1).

The equation is y = -2x + 1.

So an equation with a faster rate of change is y = -5x.

Answer:

-5 lol i tried srry

Answer:

5 <= y <= 85

Step-by-step explanation:

Since the lowest weight possible is 5lbs (just the barbell and no weights) the lowest point of the range is 5lbs (the y intercept when x = 0)

The highest weight possible is 85lbs since, there is only 8 pairs of weight plates (8 is the input value) and the pairs each weigh 10lbs (the slope of the graph) + 5lbs from the barbell (y-intercept).

Using the function given, if you input 8 as the x value, you get

85 = 10(8) + 5

So the highest value of the range is 85lbs, therefore the range is 5 <= y <= 85.  

Answer:

The first and last graph.

General Formulas and Concepts:

Algebra I

Step-by-step explanation:

In order for a systems of equations to have a solution set, the 2 graphs must intersect at at least 1 point. Here, we see that graphs 1 and 5 do not intersect each other at all.

Therefore, the rest of the graphs have solutions and #1 and #5 do no have any solutions.

Answer:

Adults =193

children=52

Step-by-step explanation:

Step one:

let the number of tickets adults be x

and the number of tickets children be y

x+y=245--------1

6.5x+3y=1410.5---2

Step two:

solve the system of equation using substitution

x+y=245

x=245-y

put x=245-y in equation 2 we have

6.5(245-y)+3y=1410.5

1592.5-6.5y+3y=1410.5

-6y+3y=1410.5-1592.5

-3.5y=-182

y=182/3.5

y=52

put y=52 in x=245-y

x=245-52

x=193

Answer:

x = - 1

Step-by-step explanation:

Given

f(x) = x³ + x² + x + 1

If x = 1 is a factor then f(1) = 0

f(1) = 1³ + 1² + 1 + 1 = 4 ≠ 0 , thus x = 1 is not a zero

f(- 1) = (- 1)³ + (- 1)² + (- 1) + 1 = - 1 + 1 - 1 + 1 = 0

Thus x = - 1 is the only zero

Answer:

0.91

Step-by-step explanation:

Answer: 0.91

Step-by-step explanation: 0.02+0.04+0.09+0.11+0.2+0.45

=0.06+0.09+0.11+0.2+0.45

=0.15+0.11+0.2+0.45

=0.26+0.2+0.45

=0.46+0.45

=0.91

Answer:

The coordinates of mage of L(5, 10) will be: (11, 3)

So, the 4th (last) option is correct.

Step-by-step explanation:

As we know that Translation means how much a point is moved to the left/right and up/down.

As the x-coordinate of the image point K(7, -3) is 7 which is 6 units right to the original point J(1, 4).

Also, the y-coordinate of the image point K(7, -3) is -3 which is 7 units down to the original point J(1, 4)

so it means the translation basically implies that

(x, y) → (x + 6, y - 7)

Hence, the coordinate of the image of L(5, 10) can also be determined by

using the same rule.

(x, y) → (5 + 6, 10 - 7) = (11, 3)

Therefore,  the coordinates of mage of L(5, 10) will be: (11, 3)

So, the 4th (last) option is correct.

Step-by-step explanation:

Answer:

Step-by-step explanation:

-x-3y-3z=16

x=-3y-3z-16

-6x+3y+2z=-27

6x=3y+2z+27

x=3/6 y + 2/6 z +27/6

x=1/2y+1/3z+9/2

4x+6y+4z=-22

4x=-6y-4z-22

x= -6/4y -4/4 z -22/4

x=-3/2y -z-11/2

Answer:

(x, y, z) = (2,-3,-3)

Step-by-step explanation: 4x+6y+4z = -22 Divide both sides by = 2x + 3y+2z= -11

To solve the system , rewrite it as two systems each consisting of two equations.

1) {-x-3y-3z = 16} {-6x+3y+2z = -27}

2) {-x-3y-3z=16} {2x+3y+2z=-11}

Solve the system of equations

1) -7x-z=-11

2)x-z=5

Write as a system of equations

{-7z-z=-11} {x-z=5}

Solve the system of equations

z = -3

x= 2

Substitute the given value of z, x into the equation : -x-3y-3z = 16

-2-3y-3x(-3)= 16

Solve for Y

y= -3

Answer:

y + 9 = [tex]\frac{1}{5}[/tex](x + 4)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = [tex]\frac{1}{5}[/tex] and (a, b) = (- 4, - 9) , thus

y - (- 9) = [tex]\frac{1}{5}[/tex](x - (- 4) ) , that is

y + 9 = [tex]\frac{1}{5}[/tex](x + 4)

Solve the compound interest problem. ​$3425 is invested at ​%7.5 compounded monthly for 2 years. a. Find the overall amount. b. Find the compound interest.

Answer:

$3977.425 ; $552.425

Step-by-step explanation:

Given that:

Principal (P) = $3425

Rate (r) = 7.5% = 0.075

Time(t) = 2 years

A = p(1 + r/n)^nt

r = rate

n = number of times compounded per year

t = time in years

A = final amount

A = 3425(1 + 0.075/12)^12*2

A = 3425(1 + 0.00625)^24

A = 3425(1.00625)^24

A = 3425(1.1612920)

A = $3977.4251

Hence, overall amount = $3977.425

Compound interest = $(3977.425 - 3425) = $552.425

Step-by-step explanation:

f(x)+g(x)=(2x^2 + 5x +6) + (3x^2 +4x - 10)

Combine like terms

5x^2 + 9x -4

f(x)-g(x)=(2x^2 + 5x +6) - (3x^2 +4x - 10)

Distribute the negative

(2x^2 + 5x +6) + (-3x^2 -4x + 10)

Combine like terms

-x^2 +x +16

Answer:

3.56X10^-6

Step-by-step explanation:

In converting numbers to scientific notation, simply move the decimal point of the number until the numerical coefficient is greater than 1 but less than 10. Be sure to take note of the following:

1. The numerical coefficient.

2. Number of times we move the decimal point. It will be the exponent with the base of 10.

3. The direction we take in moving the decimal point. If the direction is to the right, take the negative sign for the exponent. If the direction is to the left, take the positive sign for the exponent.

Here, we move the decimal point of 0.00000356 to the right 6 times. So, we have now 3.56X10^-6.
