Answer:
(6,-34)
Step-by-step explanation:
You can use the vertex formula to find the x of the vertex and then plugin the x value into the formula to find the y value.




Now plugin 6 into y=x²-12x+2
y=x²-12x+2
y=6²-12(6)+2
y=36-72+2
y=36-72+2
y = -34
Vertex = (6,-34)
Answer:
Let n and n+4 be the numbers. Then:
n² + 3(n+4)=66
n²+3n-54=0
(n+9)(n-6)=0
n=6 or -9
n+4=10
Assuming positive integers only, the numbers are 6 and 10…..
Step-by-step explanation:
100% right
If you subtract 14 from the total of 96, then you get 82. Take half of 82, and you get the number of cars washed in spring: 41!
Answer:
x = -1/7 Or 0.143 (3 dec)
Step-by-step explanation:
6(4x + 5) = 3(x + 8) + 3
= 24x + 30 = 3x + 24 + 3
24x + 30 = 3x + 27
21x + 30 = 27
21x = -3
21x/21 = -3/21
x = -1/7
Or 0.143 (3 dec)
