Answer:

x = -1

Step-by-step explanation:

x - 9.5 = -10.5

x = -10.5 + 9.5

x = -1

Answer:

-1/3 is the slope of the line

Step-by-step explanation:

Answer:

[tex]-\frac{1}{3}[/tex]

Step-by-step explanation:

y = mx + b

m is the slope and b is the y-intercept.

Subtract x from both sides of the equation.

x - x + 3y = 10 - x

3y = 10 - x

Divide each term by 3.

[tex]\frac{3y}3y} = \frac{10}{3} + \frac{-x}{3}[/tex]

[tex]y = \frac{-x}{3} + \frac{10}{3}[/tex]

Rewrite in slope intercept form.

[tex]y = -\frac{1}{3}x + \frac{10}{3}[/tex]

Answer:

x=-10, y=-20

Step-by-step explanation:

first you substiture the y in the second equation with the first

x-2x=10

then solve

1x-2x=-1

-x=10

multiply both sides by a negative to make the varible a

positive

x=-10

now we substitue the x in the first equation with -10

y=2(-10)

y=-20

Answer:

D

Step-by-step explanation:

7x - 4 = -18            (add 4 to both sides)

7x = -14                  (divide both sides by 7)

x = -2

the answer is D

Answer:

Step-by-step explanation:

Check by direct substitution.  If we begin by checking x = 3/2, we substitute 3/2 for x in (3x - 2)(x + 5), obtaining (9/2 - 2)(3/2 + 5), which is NOT zero.  Therefore x = 3/2 is not a solution.

(3*5−2)(5+5)=0  False.  x = 5 is not a solution.

(3*[-5]−2)([-5+5)=0  True.  x = -5 is a solution

x = 2/3:  (3*2/3 - 2)( ) = 0.  True  x = 2/3 is a solution

x = -2/3:  ( )( ) = -17 1/3;  so x = -2/3 is not a solution

x = -3/2:  ( ) ( ) = -22 3/4; so x = -3/2 is not a soution

Answer:

It's Balanced

Step-by-step explanation:

A simple word equation that can be used to describe the process of photosynthesis is carbon dioxide + water —> glucose + oxygen + water.  So it's a balanced chemical equation for the process can be written as 6CO2 + 6H2O —> C6H12O6 + 6O2

Answer:

The average rate of change of the function is: 0

Step-by-step explanation:

The function y = f(x) is graphed below.

From the graph it is clear that:

at x = -8, the value of f(-8) = -10

at x = -1, the value of f(-1) = -10

We have to determine the average rate of change of the function f(x) on the interval -8 ≤ x ≤ -1.

so

at x₁ = -8, f(x₁) = f(-8) = -10

at x₂ = -1, f(x₂) = f(-1) = -10

Using the formula to determine the average rate of change of the function f(x) on the interval -8 ≤ x ≤ -1.

Average rate = [f(x₂) - f(x₁)] / [ x₂ - x₁]  

                      = [f(-1) - f(-8) ] / [-1-(-8)]

                      = [-10 - (-10)] / [-1+8]

                      = [-10 + 10] / 7

                      = 0 / 7

                      = 0

Therefore, the average rate of change of the function is: 0

Answer:

3(3x + 2y) and 9x + 6y

Step-by-step explanation:

3(x + 3y + 2x - y)

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

= 3 (3x + 2y)

= (3 • 3x) + ( 3 • 2y)

= 9x + 6y

Answer:

The graph is not a function.

Step-by-step explanation:

Using the "vertical line test" to attach a vertical line to each of the points on the graph, we will find that the vertical line that passes through (0,0) has ot one, but two points on it. Remember, if the vertical line passes through more than one points, the graph is not a function. As we know, the vertical line passes through two points, those being (0, -4) and (0, -3). So, we can conclude that the graph is not a function.

Answer:

y=2x+1

Step-by-step explanation:

Answer:

34

Step-by-step explanation:

40 * .15= 6

40-6 = 34

okkk so you do 40 * .15 because you just put a decimal point before all percentages to convert it into number

40*.15= 6

then subtract 6 to the original amount

40-6=34

Answer:

1/3

Step-by-step explanation:

(2-(-1))/(6-(-3)) = 3/9 = 1/3

Answer:

y=1/3x

Step-by-step explanation:

Find the slope:  2-(-1)

                          6-(-3)

slope = 1/3

Point Slope Form: y-2= 1/3 (x-6)  plug one of the coordinates into the equation

                              y-2= 1/3x -2

                                  y=1/3x
