Answer:
C) y = 7 x minus 3
Step-by-step explanation:
Function A has a slope of -8
Function B has a slope of -2
Function C has a slope of 7
Function D has a slope of 6
The function with the steepest slope is function C.
Answer:
Let p be the amount invested at 8%. Then the amount invested at 5% would be 30,000-p. So:
.08p+.05(30,000-p)=2100
.03p+1500=2100
.03p=600
p=20,000
$20,000 was invested at 8%; $10,000 was invested at 5%

Yes because 4x3^x =12^x since the coefficient is added to the answer because it is in the 3.
Answer:
The answer is-8 (A.)
Step-by-step explanation:
Answer:
Step-by-step explanation:
Multiply the first equation by 4,and multiply the second equation by 1.
4(x−3y=−6)
1(−4x+9y=9)
Becomes:
4x−12y=−24
−4x+9y=9
Add these equations to eliminate x:
−3y=−15
Then solve−3y=−15for y:
−3y=−15 (Divide both sides by -3)
y=5
Now that we've found y let's plug it back in to solve for x.
Write down an original equation:
x−3y=−6
Substitute5foryinx−3y=−6:
x−(3)(5)=−6
x−15=−6(Simplify both sides of the equation)
x−15+15=−6+15(Add 15 to both sides)
x=9
