Answer:
x=14 , y = 21
Step-by-step explanation:
y=x-7...............1
5x+2y=7......2
reset eqn .....2
2y=-5x+7
so; y=-x-7 ×5
2y=-5x+7 ×1
5y = -5x -35
2y = -5x +7
5y-2y = -5 + 5 -35-7
<u>3y</u> = - <u>42</u>
3 3
y = 14
sub y=14 into eqn ...........1
y = -x -7
14 = - x -7
14 +7 = - x
-21 = x
x = 14 , y =-21
90 km/h is your constant.
1h 40m - 1h since we have 90 km/h.
2/3 of 90 is what we need to find for the 40 min, since 40m/60m = 2/3.
60 is 2/3 of 90.
90 + 60 = 150.
Your distance traveled is 150km.
7/12 14/24 21/36 28/48 35/60
Each answer possibility is a coordinate and represents a variety of an (x,y) point. The equation states that y = 32x + 27, so to find the correct answer, u must find the (x,y) coordinate that makes each side equal to the other. Plug in each number accordingly...
(y) = 32(x) + 27
a. (248) = 32(8) + 27
b. (379) = 32(11) + 27
c. (354) = 32(6) + 27
d. (288) = 32(9) + 27
now it’s just a matter of simplifying to see which equation is true.
a. 248 =/ 283
b. 379 = 379
c. 354 =/ 219
d. 288 =/ 315
The only equation that is true is B.
Answer:
3√265
Step-by-step explanation:
The distance between the given points is √265. If all the side are the same length on an equilateral triangle, then the perimeter is 3 times as long.
