Answer:
it will 16y-8x and common 8 is so 2y-x
Can you reformat the question?
Answer:
y=x+1
Step-by-step explanation:
first find the slope using the two coordinates:
use the slope formula- m=y^2-y^1/x^2-x^1
6-2/5-1
=4/4
=1
y=mx+b
now plug in one of the coordinates, and the slope we just found into the slope intercept formula
2=1(1)+b
2=1+b
subtract 1 from both sides
1=b
1=b; m=1,
y=x+1
Answer:
Question #3: Answer = 31
Step-by-step explanation
• Plug in 3 for x
• Plug in -4 for y
| -3(3)² + 2(-4) | -(3)(-4)
From here, simplify. Don't forget to use PEMDAS!
| -27 +8 | + 12
| -19 | + 12
19 + 12
31
Use this same method to solve for Question #2!
Let X = the number of pennies.
The number of nickels would be 2X
A penny is 0.01 and a nickel is 0.05
Now you have:
0.01x + 2(0.05x) = 8.80
Simplify:
0.01x + 0.10x = 8.80
Combine like terms:
0.11x = 8.80
Divide both sides by 0.11:
x = 8.80 / 0.11
x = 80
Pennies = X = 80 total pennies.
Nickels = 2x = 2 *80 = 160 nickels.
