answer
x=6, y=-2
explanation
-2x + 8 = y -------equ 1
3x - y = 22 -------equ 2
u can use any of the simultaneous equation method
using elimination method
rearrange first from -------equ 1
-2x+8=y
-y-2x=-8
multiple through by -1
y+2x=8 -------equ 3
rearrange first from -------equ 2
3x-y=22
-y+3=22 ------equ 4
equate 3 and 4, adding them together
y+2x=8 -------equ 3
-y+3=22 ------equ 4
0+5x=30
5x=30
x=6------equ 5
replace 6 for x in any equation
using -------equ 3
y+2x=8
y+2(5)=8
y+10=8
y=8-10
y=-2
Answer:
(x, y)=(6, -4)
Step-by-step explanation:
-2x+8=y
3x-y=22
Substitute the given value of y into the equation 3x-y=22
3x-(-2x=8)=22
Solve the equation for x
x=6
Substitute the given value of x into the equation 3x-y=22
3x6-y=22
Solve the equation for y
y=-4
The possible solution of the system is the ordered pair (x, y)
(x, y)=(6, -4)
Check if the given ordered pair is the solution of the system of equations
-2x6+8=-4
3x6-(-4)=22
Simplify the equalities
-4=-4
22=22
Since all of the equalities are true, the ordered pair is the solution of the system
(x, y)=(6, -4)

What's the slope of -1,0 and 3,-2
Answer:
-2/4
Step-by-step explanation:
What's the slope of -1,0 and 3,-2
Answer:
-0.5
Step-by-step explanation:
PLEASE, PLEASE HELP D:
write the linear equation given :
1. slope = 1/4; y-intercept =7
2. slope = -3; y-intercept = 2/3
3. slope = 2/3; y-intercept = 2/3
4. slope = -2; y-intercept = -1/2
5. slope = -3/4; y-intercept = -3
Answer:
1. y =1/4x + 7
2.y =-3x + 2/3
3. y =2/3x + 2/3
4.y =-2x - 1/2
5.y =-3/4x -3
Step-by-step explanation:
By using the slope- intercept form of the equation, y=mx + b, where m=slope and b=y-intercept, you can substitute the values of slope and the y-intercepts into the formula y=mx + b
How is (5,9) different than (-5,9)
Answer:
(5,9) is a reflection of (-5,9). One of the x values are positive while the other is negative.
The triangles are congruent. Find the measure of x.
Match up the sides for each triangle using the little marks through the sides
1 to 1, 2 to 2 and 3 to 3
When you do this you see that x corresponds to c on the first triangle.
The 3 angles in a triangle = 180.
Find c by subtracting A and B from 180
C = 180- 29-63 = 88
Now x = c so x = 88
The answer is C. 88

what does the a in y=a(1+r)x represent?
Answer:
The function is of the form y = a(1 − r)t, where 1 − r < 1, so it represents exponential decay. Use the decay factor 1 − r to find the rate of decay. Write an equation. Solve for r.
The "a" in the expression y = a (1+r)ˣ represents the initial amount.
What is the expression?An expression in math is a sentence with a minimum of two numbers or variables and at least one math operation. This math operation can be addition, subtraction, multiplication, or division.
Given, a exponential expression y = a (1+r)ˣ
The exponential growth can alternatively be calculated using the formula f(x) = a(1 + r)ˣ, where the function is denoted by the f(x) term. The initial value of your data is represented by the variable. The growth rate is represented by the r variable.
Therefore, the initial amount is been represented by "a" in the given expression.
