y = -4x + 3
8x + 2y = 8
Solve by using elimination.
Answer:
The equations are not compatible
Step-by-step explanation:
y = -4x + 3
8x + 2y = 8
substitute for y:
8x + 2(-4x + 3) = 8
simplify:
8x - 8x + 6 = 8
6 ≠ 8

what is -1/6 to the fifth power in fraction form
Answer:
The answer is 12860082/100000000000
The fraction form of the expression is -1/7776.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
[tex](-1/6)^5[/tex]
This can be simplified as,
= [tex]\frac{(-1)^5}{6^5}[/tex]
= -1/7776
Thus,
The fraction form of the expression is -1/7776.

Jasmine uses 14.24 pounds of fruit for 16 servings of fruit salad. If each serving contains the same amount of fruit, how much fruit is in each serving?
Help please
1/4x - 5 = 10 - x
1/4x - 5 = 10 -x
Add 5 to both sides:
1/4x = 15 -x
Add x to both sides:
1 1/4x = 15
Divide both sides by 1 1/4:
x = 12
(1/4)x - 5 = 10 - x
x/4 - 5 = 10 - x
(x/4)(4) - 5(4) = 10(4) - 4x
x - 20 = 40 - 4x
x + 4x = 40 + 20
5x = 60
x = 60/5
x = 12
Why is a coordinate plane called a coordinate plane?

A carpenter bought 5 identical boxes of nails. She used 25 nails fir a project and now has 435 nails left. Which equation can be solved to find the number of nails in each box.
Answer:
The equation that can be solved to find the number of nails in each box =
5x = 460
The number of nails in each box = 92 nails
Step-by-step explanation:
A carpenter bought 5 identical boxes of nails. She used 25 nails for a project and now has 435 nails left. Which equation can be solved to find the number of nails in each box.
Let the number of nails in each box be represented by x
Therefore our Equation =
5x = 25 + 435
5x = 460
Solving for x
5x/5 = 460/5
x = 92 nails
Therefore, the number of nails in each box = 92 nails

Rani deposited AED 12000 for 3 years at the rate of 5 percent per annum. Calculate the simple interest and amount at the end of the 3rd year
Answer:
the principal and the amount is 1,800 and 13,800 respectively
Step-by-step explanation:
The computation of the simple interest and amount for the end of the 3rd year is shown below:
Simple interest is
= Principal × rate of interest × time period
= 12,000 × 5% × 3 years
= 1,800
Now the amount is
= 12,000 + 1,800
= 13,800
hence, the principal and the amount is 1,800 and 13,800 respectively
