What is the slope of the line parallel to the line 4y - 7x = -4?
2 answers:
Answer:
Step-by-step explanation:
The slope of the line parallel to the line given will be the same. Parallel lines NEVER tough and cross each other. Therefore, the slope will be the same.
[add both sides by 7x]
[divide both sides by 4]
[*Remember, you are dividing both 7x and -4 by 4]
Therefore, the slope is .

Answer:
Step-by-step explanation:
Distribute.
Add 5x and subtract 15 on both sides.
Multiply -1 on both sides.
The value of the expression is 0.0265. Using exponents and power rules, the required value is calculated.
<h3>What are the exponent and power rules?</h3>The important exponent and power rules are:
- a⁻ⁿ = 1/aⁿ; negative exponent
- (ab)ⁿ = aⁿ × bⁿ; power of a product rule
- aⁿ × aˣ = aⁿ⁺ˣ; multiplication rule
- aⁿ/aˣ = aⁿ⁻ˣ; division rule
; fractional exponent
The given expression is
Using calculator: = 0.0265
Applying the exponent rule for evaluating the given expression:
Applying the negative power rule;
I.e., a⁻ⁿ = 1/aⁿ
⇒
Applying fractional exponent rule;
I.e.,
⇒
⇒ 1/
⇒ 1/37.6077
⇒ 0.0265
Therefore, the value of the given expression is 0.0265.
