Graph #1: No
Graph #2: Yes
Graph #3: No
Graph #4: No
Graph #5: No
Graph #6: Yes

Reasoning:

The vertical line test is a test that determines wether a graph is a function or a relation. The vertical line test shows that if you construct a vertical line through any point on the graph, then the vertical line should only intercept the graph once for it to be a function.

While painting, Sam notices that 1/2 cup of paint covers 1/3 of a sign. What is the amount of paint needed to cover the entire s

Verdich [7]

To answer, determine the amount of paint that is needed in order to cover the whole of the sign. If we use the ratio and proportion and letting x be the unknown amount. The equation would be,
1/2 / 1/3 = x / 1
The value of x from the equation is equal to 1.5. Thus, the answer is letter D. 3/2 cups.

Explain why the graph of the equation g(x) = -(x + 1 ) - 3 would be a parabola opening downward.

sashaice [31]

Answer: Because the a-value is negative.

Step-by-step explanation:

The vertex form of a quadratic equation is: y = a(x - h)² + k where

"a" is the vertical stretch
-a is a reflection over the x-axis
h is the horizontal shift (positive = right, negative = left)
k is the vertical shift (positive = up, negative = down)

Given: g(x) = - (x + 1)² - 3

↓

a= -1

Since the a-value is negative, the parabola will be reflected over the x-axis which will change the curve from (U-shaped) to (∩-shaped).

What is the product of (7 x 10^-5) x (5 x 10^-8) (7 x 10^-5) x (5 x 10^-8) = ? x 10^?

arsen [322]

Answer:

$3.5\times10^-^1^2$

Step-by-step explanation:

$(7 \times 10^-5) \times (5 \times 10^-8)$

Evaluate

$(7 \times 5)\times(10^-^5\times10^-^8)$

$35\times10^-^5^-^8$

$35\times10^-^1^3$

$35\times10^1\times10^-^1^3$

$3.5\times10^1^-^1^3$

$3.5\times10^-^1^2$

Thus, the answer is $3.5\times10^-^1^2$

Square A has a side length (2x-7) and Square B has side length (-4x+18). How much bigger is the perimeter of Square B than Squar

mihalych1998 [28]

How much bigger is B than A , so Side length B- A = (-4x+18) - (2x-7) = -6x+25
So perimeter = 4x length = 4x(-6x+25) = -24x+100 = 100-24x
How much bigger? 100-24X
