The substitution method means you replace the variable in one equation with the other equation, so your new equation is x+4x-8=10. Add 10 to both sides to get 5x=18. Divide both sides by 5 to get x=3.6. This is a weird equation, but then to get y, work backwords. 3.6 times 2=7.2. 7.2-4=3.2 y=3.2. Finally to finish checking solve the equation as normal. 3.6+6.4=10. I hope this helped! Please give brainliest!
Your final answer is x=3.6 y=3.2
Answer:
Step-by-step explanation:
A(1,2) ---->(x1,y1)
B(8,16) ----->(x2,y2)
m:n = 5:2
Answer:
c. y = x - 6.
Step-by-step explanation:
It's a straight line whose general form is y = mx + c.
The slope is (0, -6) / (6, 0)
= -6 / -6
= 1 so the coefficient of x , (m) is 1.
The value of c ( the y-intercept) is -6.
Answer:
It’s not allowing me to place done the work but the answer is 8 sorry!
Angle B = 54°
Step-by-step explanation:
complimentary means they add up to 90
54 + 36 (angle A) = 90
also x= 51
