Answer:
y – 21 = 5.2(x – 4)
Step-by-step explanation:
Since y is the distance and 21 is how many miles Izzy runs, then you subtract it with ...
I don't know I just figured it out.
Answer:
<h2>B and D</h2>
Step-by-step explanation:
This equation is true in either case, because the expression is equivalent to itself, that means the equation is true for all positive real numbers including the zero.
Therefore, the right answers are B and D, both numbers are true solutions of the expression.
The answer is 3/8 hope this helped
Answer:
x= 8 and x=-9
Step-by-step explanation:
The x intercepts are found when we set y = 0
0 = (x-8) (x+9)
Using the zero product property
x-8 =0 and x+9=0
x= 8 and x=-9
It looks like you are trying to factor a quadratic. So you are looking for the numbers that when you multiply them, you get the top number (100), but when you add them you get the bottom number (-20).
Those two numbers are -10 and -10.
Hope that helps!
