Answer:
x = 1.2
y = 6.6
Step-by-step explanation:
1) y= -2x+9
2) 8x-3=y
Substitute y in equation 1 using y in equation 2.
8x - 3 = -2x + 9
+ 3 on both sides
8x = -2x + 12
+ 2x on both sides
10x = 12
x = 1.2
To find y, plug in x
8x - 3 = y
9.6 - 3 = y
6.6 = y
Hope this helps :)
Answer:
It takes 3.5 seconds for the ball to hit the ground
Step-by-step explanation:
By finding the x intercepts you can determine when the ball hits the ground.
the second x intercept is (3.5,0), which means the ball hits the ground at 3.5 seconds
Step-by-step explanation:
Step 1: 25*x-((1/125)^(4*x-5))=0
step 2: simplify 1/125
step 3: 25x-(1/125)(4x-5)=0
pls i need one more brainly
5(x^2 - 14x + 258/5)
= 5((x-7)^2 -49+258/5)
= 5((x-7)^2 + 13/5)
= 5(x-7)^2 + 13
I belive this is how it should be done
