Y = 3
y = - 2x + 3
sub in 1 y for another
3 = -2x + 3
3 - 3 = -2x
0 = -2x
0 = x....solution is (0,3)
===================
y = 3x + 2
y = -3x - 4
sub in 1 y for another
3x + 2 = -3x - 4
3x + 3x = -4 - 2
6x = -6
x = -6/6
x = -1
now sub in -1 for x in either of the original equations to find y
y = 3x + 2
y = 3(-1) + 2
y = -3 + 2
y = -1
solution is (-1,-1)

Ratio Ralph can ride his bike 5 miles in 20 minutes. How many miles can he ride in
Virty [35]

Answer:

22.5 miles

Step-by-step explanation:

There are 3, 20 minute increments in an hour, and 1 and a half 20 minute increments in half an hour, so, you simply add 3 + 1.5 which equals 4.5.

Then, multiply 5 (miles) by 4.5 to get 22.5 (miles).

the ratio of the heights of two similar triangles is 6:5 if the perimeter of the larger triangle is 49.2 feet. find the perimite
Mademuasel [1]

Answer:

41 feet

Step-by-step explanation:

We apply the theorem below:

If two similar triangles have a scale factor of a : b, then the ratio of their perimeters is a : b.

Let x be the perimeter of the smaller triangle

If the ratio of their heights is 6:5 and the perimeter of the larger triangle is 49.2 feet,

6:5=49.2:x

6/5=49.2/x

Cross multiplying

6x=49.2 X 5

6x=246

x=246/6=41

The perimeter of the smaller triangle is 41 feet
