Answer:
At x=3 the value of the function is 4
Step-by-step explanation:
we have the points
(-2,3) and (3,4)
That means
(-2,3)
For x=-2
The value of the function y is equal to 3
(3,4)
For x=3
The value of the function y is equal to 4
therefore
At x=3 the value of the function is 4
Answer:
Step-by-step explanation: Step 1: Simplify both sides of the equation.
3(y+8)=36
(3)(y)+(3)(8)=36(Distribute)
3y+24=36
Step 2: Subtract 24 from both sides.
3y+24−24=36−24
3y=12
Step 3: Divide both sides by 3.
3y/3=12/3
y=4
Answer:
10.8 or 10 4/5
Step-by-step explanation:
4 1/2 * 2/25 = 10 4.5
The equation would be y=0.45x.
Let x be the number of cookies Matt made. Since Phil made 25% more, and 100%+25%=125%=125/100=1.25, the number of cookies Phil made can be represented by 1.25x.
Together the cookies they made are represented by x+1.25x=2.25x
Since there were 20% of the cookies remaining, this means they sold 100%-20%=80%=80/100=0.8 of the cookies:
0.8(2.25x) = 1.8x
Each cookie sold for 0.25, so we have
0.25(1.8x) = 0.45x
Letting y be the money they make, we have
0.45x=y
