Answer:

14) y = 81

15) n = 6

Step-by-step explanation:

14)

54:30 = y:45

cross multiply: 45(54) = 30y, so y = 81

15)

6:3 = 12:n

cross multiply: 12(3) =6n, so n = 6

Help please need help with this stuff thank you again for helping

Slope intercept form: y = mx + b

Where m = slope and b = y-intercept.

By looking at the graph, we can see that the line cuts at 1/2 on the y-axis, therefore eliminating option D.

So now we have: y = mx + 1/2

Next, we'll find the slope. \frac{y_2-y_1}{x_2-x_1}

Plug the coordinates into the formula.

\frac{3-(-2)}{4-(-4)}= \frac{5}{8}

So our slope is 5/8 and the y-intercept is 1/2.

Option A is the answer.

John has less than 15 video games what is the inequality?
lidiya [134]

Answer: well, we don't have another number so i'll use variables

VG < 15

An easy way to remember what is the lesser value is to think of an alligator; the alligator wants to eat the bigger prey so in your case the bigger prey would be 15.

Find the x- and y- intercepts of the equation 7x+ 14 y=28
7nadin3 [17]

Chapter : Linear equations

Lesson : Math for Junior High School

7x + 14y = 28

if want to find x and y, we must substitution value 0 to the equation x and y :

# If x = 0, then :

7x + 14y = 28

= 7(0) + 14y = 28

= 0 + 14y = 28

= 14y = 28 → y = 28/14

= y = 2

# If y = 0, then :

7x + 14y = 28

= 7x + 14(0) = 28

= 7x + 0 = 28

= 7x = 28 → x = 28 / 7

= x = 4

and that result was proven x = 4 and y = 2
