Answer:
step 1
Step-by-step explanation:
step 1 he made the mistake
should have been:
h - 2 = 20
#2.
a) 1/4m + 3 = 2
1/4m = -1
m = -4
b) 4y - 3(y + 8) = 12
4y - 3y + 24 = 12
y = -12
For #10, letter b. Do the same thing you did with letter a.
The equation is already given.
You have your y-intercept: -8, and your slope: 3/1.
These two create two different points you can add to your data table.
(0, -8) and (1, 3)
y:-8, 3
x: 0, 1
Answer:
Step-by-step explanation:
3z + 9 + 142 = 4z + 5
3z + 151 = 4z + 5
-z + 151 = 5
-z = -146
z = 146
answer is B
exactly one solution
Answer:
Why the rest of the answers or bubbles are hidden???
Step-by-step explanation:
Your answer is 6% of x.
We can write the given information as equations to find the answer:
Another way to write "20% of x" is to write 0.2x, so therefore 0.2x = y
You can also write "30% of y" as 0.3y, so 0.3y = z
Now we can substitute in the first equation to the second equation, as we know what y equals in terms of x:
0.3(0.2x) = z
Multiplying out we get:
0.06x = z, and 0.06 as a percentage is 6%
I hope this helps!
