Step-by-step explanation:
Use PEMDAS to solve all
1.
8^2 - 6*2
8*8 - 6*2
64 - 12 = 52
2.
4^2 * 3 + 4 * 2
4 * 4 * 3 + 4 * 2
16 * 3 + 8
48 + 8 = 56
3.
9^2 - 2(5+3)
9 * 9 - 2(8)
81 - 16 =65
Answer:
Step-by-step explanation:
-7x + 12 + (-8x + 48) = 180
-15x + 60 = 180
-15x = 120
x = -8
m<BDC= -7(-8)+ 12 = 56 + 12 = 68
m<CBA = -8(-8)+48 = 64+48 = 112
Hello,
Equation is y=k(x-1)²-9
and when x=0,y=-6==>-6=k*1²-9==>k=3
y=3(x-1)²-9
when y=0, 3(x-1)²-9=0
==>(x-1-√3)(x-1+√3)=0
x-intercepts are (1+√3,0) and (1-√3,0)
Answer B.
Answer:
25
Step-by-step explanation:
If it gives a result of -4 then our equation will have .... = -4
If we subtract 9 from the quotient of a number and 5 we have x/5 - 9
Our equation is:
x/5 - 9 = -4 add 9 to both sides
x/5 = -4 + 9
x/5 = 5 multiply both sides by 5
x = 5(5)
x = 25
Check: 25/5 - 9 = 5-9 = -4
Answer checks as correct from information given
All of the above are true
