Answer:
p=9 m=21 x= - 30
Step-by-step explanation:
p=9
m=21
x= - 30
Step-by-step explanation:
1) 3p + 5 = 14
3p = 14 - 5
3p = 9
p = 9/3
⇢ p = 3
2)
m/7 - 3 = 0
m/7 = 3
m = 3 × 7
⇢ m = 21
3) 8 + x/2 = -7
x/2 = -7 - 8
x/2 = - 15
⇢ x = -30

Rewrite the equation 2y - 4x = 10 in function notation where f(x)= y.
f(x)=
Answers
Answer:
Answer:
f(x) = 5 + 2x
y+4x^2-1 is the same as y=-4x^2+1, then replace y with f(x); f(x)=-4x^2+1. After you do that, replace x with 2; f(2)=-4(2)^2+1. 2^2=4, 4 times -4=-16, -16+1=-15. So f(2)=-15.
Answer:
f(x) = 5 + 2x
Step-by-step explanation:
2y - 4x = 10
+4x +4x
2y = 10 + 4x
Now we have a new equation but we have to isolate the variable y.
[tex]\frac{2y}{2}[/tex] = [tex]\frac{10 + 4x}{2}[/tex] Then divide to solve for y.
y = 5 + 2x
Since f(x) is the same thing/equal to y we can just replace that.
f(x) = 5 + 2x

Can someone explain this to me!!! Will give the brainliest!!!!
Answers
Answer:
88 degrees
Step-by-step explanation:
First, notice that when you rotate a point 272 degrees clockwise, there will be 88 more degrees before it returns to its original point (since a 360 turn is equivalent to not moving, and 360-272=88).
Because of that, we can deduce that rotating a point 88 degrees counterclockwise will be equivalent to rotating it 272 degrees clockwise.
We can know that that's the smallest possible positive answer, because any angle smaller than 360 will be the smallest possible way to express it.
2) Ruth borrows $440 at 0.6% simple interest per month. When
Ruth pays the loan back 4 years later, how much interest does
Ruth pay?
Answers
Answer:
$10.56
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 0.6%/100 = 0.006 per year,
then, solving our equation
I = 440 × 0.006 × 4 = 10.56
I = $ 10.56
The simple interest accumulated
on a principal of $ 440.00
at a rate of 0.6% per year
for 4 years is $ 10.56.
Answer:
450.56
Step-by-step
440 x 0.006 x 4 + 440 =450.56
