Answer:
Mikhail's age is 25 years old
Step-by-step explanation:
Let's make an equation: Say Mikhail is x, so Gabby would be 2*x=2x
If the sum of their ages equals 75, then x+2x=75, and x=2x=3x, so 3x=75.
75/3=25
Answer:
y= 3x - 15
Step-by-step explanation:
parallel lines have the same slope, but different y intercepts
Answer:
-2y^2 + y +32
Step-by-step explanation:
The variable with the highest exponent is y^2
If y = 6 when x = 8, then value of "x" when y = 9 is equal to 12
<u>Solution:</u>
Given that , In a certain function, y varies directly with x
And x = 8 when y = 6,
We have to find what will be the value of x when y = 9
Now, from the given information,

where c is the proportionality constant

Hence, x value is 12 when y value is 9
Answer:
Diego: y = 11 + 5 x
Emilia: y = 60 - 2 x
Step-by-step explanation:
y for saving and x for weeks
Diego: y = 11 + 5 x
Emilia: y = 60 - 2 x
