First step
Using substitution you can fill 2x + 11 in for the y part of the first equation
This will look like: 2x + 11 = -x^2 -2x + 8
Second step
Now we need to solve for the variable by combining like terms you can start by adding x^2 + 2x -8 to both sides
You get 0 = x^2 +4x +3
Third step
Factor
(X+3)(x+1)=0
If you need the y values you can fill in x= -3 to the second equation y= 2(-3) + 11 and y=5
First point is (-3,5)
The other point is found by filling x=-1 into the second equation: y= 2(-1) +11 and y = 9
Second point is (-1,9)
Answer:
A
Step-by-step explanation:
Answer:
$1.54
Step-by-step explanation:
18% of $15.85 is 2.853, so your total is $18.703
20% of $14.30 is 2.86, so their total is $17.16
So the difference is $1.543, rounded (since your dealing with money) would be $1.54
Answer:
Mass=1068gr
Step-by-step explanation:
Volume= 7.5 cm x 2.53 cm x 7.15 cm=135.7cm^3
Density=7.87gr/cm^3
Mass=Density*Volume=135.7*7.87=1068gr
