5(2x + 6) = -4(-5 - 2x) + 3x

Distribute: 10x + 30 = 20 + 8x + 3x

Combine like terms: 10x + 30 = 20 + 11x

Simplify: 10x + 30 - 20 = 20 - 20 + 11x

Simplify: 10x - 10x + 10 = 11x - 10x

Divide for x: 10/1 = 1x/1

x = 10

10x+30=20+11x

10x=20+11x-30

10x-11x=-10

-1x=-10

X=10

70=(4x+36)/2 figure this out please

adell [148]

Answer:

$\boxed{\bold{\huge{\boxed{x = 26}}}}$

Step-by-step explanation:

$70 = \frac{4x+36}{2}$

Multiplying both sides by 2

$70 * 2 = 4x+36$

$140 = 4x+36$

Subtracting 36 to both sides

$140 - 36 = 4x$

$104 = 4x$

Dividing both sides by 4

$26 = x$

$x = 26$

Look at the following graph of the given equation. Determine whether the equation is a function. Explain why or why not.

Vadim26 [7]

The equation $y=2x+2$ is a function

Explanation:

Given that the graph contains the coordinates $(-1,0)$ , $(0,2)$ , $(1,4)$ and $(2,6)$

We need to determine whether the equation $y=2x+2$ is a function.

To determine the equation is a function, let us substitute the coordinates in the equation and check whether it satisfies the equation.

Let us substitute the coordinate $(-1,0)$ in the equation $y=2x+2$

Thus, we have,

$0=2(-1)+2$

$0=-2+2$

$0=0$

Thus, the coordinate $(-1,0)$ satisfies the equation $y=2x+2$

Substituting the coordinate $(0,2)$ in the equation, we have,

$2=2(0)+2$

$2=2$

Thus, the coordinate $(0,2)$ satisfies the equation $y=2x+2$

Substituting the coordinate $(1,4)$ in the equation $y=2x+2$

$4=2(1)+2$

$4=4$

Thus, the coordinate $(1,4)$ satisfies the equation $y=2x+2$

Substituting the coordinate $(2,6)$ in the equation, we get,

$6=2(2)+2$

$6=6$

Thus, the coordinate $(2,6)$ satisfies the equation $y=2x+2$

Hence, the coordinates $(-1,0)$ , $(0,2)$ , $(1,4)$ and $(2,6)$ satisfies the equation $y=2x+2$

Thus, the equation $y=2x+2$ is a function.

If the tip varies directly with the number of guest,which equation represents the relationshipbbetween the tip,t,and the number

sergejj [24]

If the tip, t, varies directly with the number of guests, g, then it means that any change in tip there is a corresponding change in the number of guests. When the tip increases the number of guests increases as well. Therefore,

t α g

To change the it to equal sign, we incorporate a proportionality constant, k.

t = kg

This equation will represent the relation of t to g.

Tomas drew a rectangle with an area of 6 square centimeters. What is the greatest possible perimeter for this rectangle.

Delvig [45]

6 by 1.

This is the greatest because it makes 14 (6+6+1+1), which is greater than 3 by 2, which is only 10. (3+3+2+2)

Hope this helps!
