Step-by-step explanation:
it kinda like subtracting to get your answer
Answer:
X=-1
Y=-8
Step-by-step explanation:
8x+y=-16
3x-y=5
11x=-11
x=-1
8x+y=-16
8(-1)+y=-16
-8+y=-16
y=-16+8
y=-8

<em><u>Or</u></em> </h2>
3x-y=5
3(-1)-y=5
-3-y=5
-y=5+3
-y=8
y=-8
Answer:
a number between −1 and +1 calculated so as to represent the linear dependence of two variables or sets of data.
Answer:
x = 25, The angles of the triangle are 60*, 45*, and 75*.
Step-by-step explanation:
The sum of the angle measure is 180 so we can form this equation:
60 + (x + 20) + 3x = 180
Now isolate the variable to find x.
(x + 20) + 3x = 120
4x + 20 = 120
4x = 100
x = 25
Now solve for the angles of the triangle.
3(25) = 75
(25 + 20) = 45
Answer:
x = 6
Step-by-step explanation:
The isosceles triangle is divided into two forming two right triangles
in right triangles the square value of hypotenuse is equal to sum of other two side lengths
x^2 + 4^2 = 52
x^2 + 16 = 52 subtract 16 from both sides
x^2 = 36 find the root for both sides
x = 6
