Answer:
x = 5/2 y = 3/2
Step-by-step explanation:
You need to write what the question is besides the information in the problem. I assume the question is to find the values of x and y.
Going on that premise, Let equation (1) be -5x + 3y = -8 and
equation (2) be 3x - 7y = -3
Lets multiply (1) by 3 and (2) by 5 and we get equations (4) and (5)
(4) -15x + 9y = -24 and (5) 15x - 35y = -15 Now add (4) and (5)
-15x + 9y = -24
<u> 15x - 35y = -15</u>
-26y = - 39
y = 3/2 Now substitute y = 3/2 in equation (1). -5x + 3)(3/2) = -8
-5x + 9/2 = -8
-10x + 9 = -16
-10x = -25
x = -25/-10 = 5/2
x = 5/2 y = 3/2
Check: Substitute your answers into equation (2) and see if they work.
3(5/2) -7(3/2) = 15/2 - 21/2 = -6/2 = -3 Hooray! We have the correct values for x and y that makes each equation true
Answer:
4 feet wide because to find the perimeter you add all the numbers around

slope=y2-y1/x2-x1
y1=4 y2=16
x1=3 x2=5
slope=16-4/5-3
slope=12/2
slope =6
Answer:
64°; no
Step-by-step explanation:
Since XW bisects angle X, we have ...
angle YXZ = 2(angle WXY)
(4x +6) = 2(3x -5)
4x +6 = 6x -10 . . . eliminate parentheses
16 = 2x . . . . . . . . add 10-4x
8 = x
Then angle XZY = 8x° = 8·8° = 64°. The angle WXZ is (3x-5)° = (3·8-5)° = 19°, an angle that is not complementary to 64°. XW cannot form a right angle with YZ, so it is not an altitude.
Angle XZY is 64°, and XW is not an altitude.

➷ Split 84 into two numbers that can be multiplied to give 84
42 x 2 = 84
2 is a prime number so we don't need to simplify it further, however, 42 isn't a prime number.
42 can be split into :
21 x 2 = 21
So far, we have 21 x 2 x 2 = 84
The 21 can be split further:
7 x 3 = 21
Therefore, the answer is 7 x 3 x 2^2
