Answer:

Option C is correct

(-8, 0)

Step-by-step explanation:

x-intercept:

The point where function cuts x-axis that is point where y = 0.

Given that:

A graph with equation of line.

we have to find the find the x-intercept of the function graphed.

By definition of x-intercept.

From the given graph,

it can be seen clearly that the given line crosses that x-axis at (-8, 0)

⇒x-intercept = (-8, 0)

Therefore, the x-intercept of the function graphed is, (-8, 0)

Write an equation of the line that passes through (2,7) and is parallel to the line shown ( please help !! )

Anna007 [38]

Answer:

$y=2x+3$

Step-by-step explanation:

We will first need to determine the slope of the line shown.

We know that it passes through the two points (-2, -2) and (1, 4).

Thus, we can use the slope formula to find the slope between the two points:

$\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Let (-2, -2) be (x₁, y₁) and let (1, 4) be (x₂, y₂). Substitute:

$\displaystyle m=\frac{4-(-2)}{1-(-2)}=\frac{6}{3}=2$

Hence, the slope of the original line was 2.

Since we want the new line to be parallel, the slope of the new line must also be 2.

We know that the slope is 2 and it passes through the point (2, 7).

So, we can use the point-slope form:

$y-y_1=m(x-x_1)$

We will substitute 2 for m. We will also let (2, 7) be (x₁, y₁). Substitute:

$y-7=2(x-2)$

Solve for y. Distribute the right:

$y-7=2x-4$

Add 7 to both sides. Hence, our equation is:

$y=2x+3$

How do you write 5.6 as a mixed number as a decimal?

Mama L [17]

5.6 in a fraction is 5 and 6/10, or 5 3/5. To get the mixed fraction, multiply the whole number (to the left) by the denominator (bottom of fraction), and add to the numerator (top of fraction). So 5 × 5 = 25 + 3 = 28. So it'd be 28/5.

Paraphin [41]

The first one is the last answer because you subtract 18 and when you divide you change the inequality symbol

the second one is the last answer for the same reason

the 3rd one is x<-1.25

the 4th one is x<8/15

Jose can read 7 pages of his book in5 minutes. at this rate, how long will it take him to read the entire 175-page book?

Lera25 [3.4K]

Since 7 pages could be in 5 min.
So time required by 1 page 5/7 min.
So time required by 175 pages =175×5/7=125 min.
= 2 hours and 5minutes
