Y-5=-1/2(X-2)
the simplified version of this equation (so you can plug into a calculator) is
Y=-1/2x+6
X=-6
you could either multiply 9 on both sides or distribute the 9 and isolate the variable
Answer:
you have to make x-3 and x-7 equal to zero...
x = 3 or x=7
"A"
Step-by-step explanation:
If Mallory makes $42.50 per hour and she works 20 hours a week, we multiple those two and we get:
42.5 * 20 = 850
So she earns $850 per week.
Mallory saves half of that amount she would have $425 per week.
In 4 weeks she would have:
425 * 4 = 1700
Mallory will save $1,700 in four weeks.
The first one is the second one. t(n)=20n+480
Question 4: is the first one t(n)=8n+15
