If you arrange this properly in the slope intercept form (y=mx+b) so just make it arranged in this format.
4x-7y=-28
Subtract 4x
-7y=-28-4x
Rearrange.
-7y=-4x-28
Divide by -7
y=4/7x+28
The number next to x is your slope and the other number is your y-intercept.
Answer:
44.7 degrees
I took a quiz with this question and that was the correct answer.
Factorising is when you put the equation in expandable brackets.
Using decimal multipliers, it is found that the value of x is of 16.67.
<h3>What is a decimal multiplier?</h3>
Increases of a% or decreases of a% re represented by decimal values, as follows:
- The equivalent multiplier for an increase of a% is given by:

- The equivalent multiplier for an decrease of a% is given by:

In this problem:
- The price at the beginning of January was of a.
- Increase of 20% in January, hence
.
- Decrease of 20% in February, hence
.
- Increase of 25% in March, hence
.
- Decrease of x% in April, hence

The price of gasoline at the end of April was the same as it had been at the beginning of January, hence:






The value of x is of 16.67.

Answer:
One of the hardest math problems ever.
Step-by-step explanation:
In mathematics, the Riemann hypothesis is a conjecture that the Riemann zeta function has its zeros only at the negative even integers and complex numbers with real part. Many consider it to be the most important unsolved problem in pure mathematics.
