Answer:
-4
Step-by-step explanation:
-36v+42=186
-36v=144
v=-4
Answer:
b) -10
Step-by-step explanation:
x^2 + 3x + k = (x - 2)(x - a)
(x - 2)(x - a) = x^2 - 2x - ax + 2a = x^2 + [-2 - a)x] + 2a
-2 - a = 3
2a = k
a = -5
k = 2(-5) = -10
Answer: b) -10
So we see our equation, clear:
y=8^x
Let's just plug in values of x from 1-4.
y= 8^1=8; So, it would be (1,8).
y= 8^2=64; So, it would be (2, 64).
y = 8^3= 512; So, it would be (3,512).
y= 8^4 = 4096; So, it would be (4, 4096).
Answer: y=5+4/5
Step-by-step explanation:
1) Move all terms to the left:
y-(29/5)=0
2) Add all the numbers together, and all the variables
y-(+29/5)=0
3) Get rid of parentheses
y-29/5=0
4) Multiply all the terms by the denominator
y*5-29=0
5) Multiply elements
5y-29=0
6) Move all terms containing y to the left, all other terms to the right
5y=29
y=29/5
y=5+4/5
