The slope-intercept form:

$y=mx+b$

m - slope

b - y-intercept → (0, b).

Read two points from the graph.

y-intercept = (0, 2) → b = 2

x-intercept = (-5, 0)

The formula of a slope:

$m=(y_2-y_1)/(x_2-x_1)$

Substitute:

$m=(0-2)/(-5-0)=(-2)/(-5)=(2)/(5)$

Therefore your answer is

$\boxed{C.\ y=(2)/(5)x+2}$

Answer:

The best answer is C. y = 2/5x + 2

A researcher found that 55% of families in the United States have one child under the age of 21, 22% have two children under the age of 21, 15% have three children under the age of 21, 5% have 4 children under the age of 21and 3% have 5 or more children under the age of 21. If a family is selected at random, what is the probability the family has 1 or 3 children under the age of 21?

Answers

Answer:

67% or 0.67

Step-by-step explanation:

Given that:

P(1 child under age 21) = 55%

P(2 children under age 21) = 22%

P(3 children under age 21) = 15%

P(4 children under age 21) = 5%

P(5 or more children under age 21) = 3%

If a family is selected at random, what is the probability the family has 1 or 3 children under the age of 21?

P(1 or 3 children under age 21):

Either the selected family has 1 child under 21 years of age OR the selected family has 3 children under 21 years of age ;

P(1 child under age 21) + P(3 children under age 21)

= 55% + 15%

= 67% = 0.67

Rewrite the following linear equation in slope-intercept form. Write your answer with no spaces. y+2=4(x-3)

Answers

Answer: The required slope-intercept form of the given linear equation is

$y=4x-14.$

Step-by-step explanation: We are given to write the following linear equation in slope-intercept form :

$y+2=4(x-3)~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)$

We know that

the slope-intercept form of a straight line is written as

$y=mx+c,$

where 'm' is the slope and 'c' is the y-intercept of the line.

From equation (i), we have

$y+2=4(x-3)\n\n\Rightarrow y+2=4x-12\n\n\Rightarrow y=4x-12-2\n\n\Rightarrow y=4x-14.$

Thus, the required slope-intercept form of the given linear equation is

$y=4x-14,$ where slope, m = 4 and y-intercept, c = -14.

it would be y=4x-14.

Subtract 3/y-2 - 1/y+3

Answers

to subtract fractions, we need a common denominator.

$(3)/(y-2)$ - $(1)/(y+3)$

the common denominator will be (y-2)(y+3)

$(3(y+3)-1(y-2))/((y-2)(y+3))$
$(3y + 9 - y + 2)/((y-2)(y+3))$
$(2y + 11)/((y-2)(y+3))$

The answer above will be the simplified form.

Use the zeros of the following quadratic to find the x-value of the vertex.y = x2 – 4x – 5
A.5
B.2
C.–2
D.–5

Answers

1. y = x^2 - 4x - 5
= x^2 - 4x + 4 - 4 - 5
= (x^2 - 4x + 4) -4 - 5
y = (x-2)^2 - 9 Here, the vertex is at (2, -9)

2. x = 2 (the vertical line that goes through the vertex)
3. The graph of this function is called a parabola. To graph a parabola, use
its vertex (in this case, (2, -9) ) and y-intercept (y = -5). The y-intercept is the constant in the given equation. Use the fact that the vertical line through the vertex is a line of symmetry. Plot the point corresponding to the y-intercept that lies on the other side of the vertical line x = 2.

4. The graph is translated 2 units to the right and 9 units down.

The answer is B.) 2
