Answer:

Step-by-step explanation:

A. Both of the y intercepts are y=-3 which isn’t very helpful but if you use the formula gradient = change in y ÷ change in x, then you get gradient = 6÷5

C and D are definately not the correct answer because the y-intercept in the graphs are not -3. the answer is A because notice that the line is on the y-intercept -3. the formula to find the slope is y2 - y1/x2 -x1. pick any two points in the graph and they should give you the answer you're looking for. (x, y)

(0, -3) (5, 3)

3 - (-3) / 5 - 0

18/5

y= 6/5x-3 is the same thing as y=18/5x-3

I really hope this helps! Good luck!

Movies at the rental store are $3.75 each. Snacks and drinks are $1.89 each. Round each amount to the nearest dollar to estimate

hodyreva [135]

Answer:

$14.00

Step-by-step explanation:

First you round 3.75 to 4.00 because 7 is greater than 5 so it would turn the 3 to 4 than add the zeros it's 4.00. Second You multiply by three so 4.00 × 3 you will get 12.00. Than you round 1.89 to 2.00 because 8 is greater than 5 so it would turn to the 1 to the 2 than add the zeros it's 2.00. Finally you add them together and get $14.00

Find the coordinates of point B along a directed line segment from A(3,4) and

andreev551 [17]

We have been given two points. $A(3,4)$ and $C(3,9)$ . We are asked to find the point B such that it divides line segment AC so that the ratio of AB to BC is 4:1.

We will use segment formula to solve our given problem.

When a point P divides segment any segment internally in the ratio $m:n$ , then coordinates of point P are:

$[\right x=\frac{mx_2+nx_1}{m+n},y=\frac{my_2+ny_1}{m+n}\left]$

$(x_1,y_1)=(3,4)$ and $(x_2,y_2)=(3,9)$ .

$m=4,n=1$

Upon substituting our given information in above formula, we will get:

$[\right x=\frac{4(3)+1(3)}{4+1},y=\frac{4(9)+1(4)}{4+1}\left]$

$[\right x=\frac{12+3}{5},y=\frac{36+4}{5}\left]$

$[\right x=\frac{15}{5},y=\frac{40}{5}\left]$

$[\right x=3,y=8\left]$

Therefore, the coordinates of point B would be $(3,8)$ .

Radius is between 7 inches and 14 inches. ⇒ A) 7 < r < 14

√18 + √2 = √9 *2 + √2 = 3√2 + √2 = (3+1) √2 = 4√2

D) It is irrational and equal to 4 multiplied by the square root of 2.

Find the sum. Express your answer in simplest form.

Marina86 [1]

Answer:

$\frac{10x^2+3}{y^2+4}$

Step-by-step explanation:

When adding rational numbers, if the denominator is the same you simply keep the denominator (bottom of fraction) as it is and apply the operation given to the numerator ( top of fraction )

So we have $\frac{6x^2+5}{y^2+4} +\frac{4x^2-2}{y^2+4} =\frac{(6x^2+5)+(4x^2-2)}{y^2+4}$
