Answer:
A.
Step-by-step explanation:
If
AND
y = x + 7, then by the transitive property of equality:

We can solve for the values of x by getting everything on one side of the equals sign and then solving for x:

We can factor out the common x to get:
x(x + 1) = 0
which tells us by the Zero Product Property that either
x = 0 and/or x + 1 = 0 and x = -1
We are expecting 2 solutions for x since this is a second degree polynomial. We will sub both -1 and 0 into y = x + 7 to solve for the corresponding values of y
y = 0 + 7 so
y = 7 and the coordinate is (0, 7)
y = -1 + 7 so
y = 6 and the coordinate is (-1, 6)
Answer:
a) 5x=8 use a calculator and use distributive property
b) 22=3x+5 -18
22=3x-13
9=3x
x=3
distributive property
c)-48= -8x-20+5x-1
-48= -3x-21
-27= -3x
x=7
distributive property
Step-by-step explanation:
Their ratio would be: Cookie / Donut = 4/3
Let, the amount of money earned from Donut = x
It would be: 4/3 = 375 / x
x = 375/4 * 3
x = 1125/4
x = 281.25
In short, Your Answer would be $281.25
Hope this helps!
Answer:
v=520 -10t
Step-by-step explanation:
the rate of decrease is given a variable to calculate the rate of change. v is represented by 520 - the number of minutes.
In exact form it would be 15/8
