The answer is c because you have to divide first and round the decimal by one place to the left or right
Answer:
x = -1.75 , +/- 1.1892i.
Step-by-step explanation:
4x5 + 7x4 + 36x + 63) = (4x + 7)
4x^5 + 7x^4 + 32x + 56 = 0
x^4(4x + 7) + 8(4x + 7) = 0
(x^4 + 8) = 0 or 4x + 7 = 0
4x + 7 = 0
x = -1.75.
4x^4 = -8
x^4 = -2
x = +/- ⁴√-2
x = +/- 1.1892 i.
It’s only 5 points but I’ll answer the first one he makes 10$ an hour so if they want you to Wright it in a equation it’s would be y=10x+0
The equation that could be used to find how many gallons Erin would need to drive 92 miles is 92 = 23g (option c)
<h3>How many gallons is needed to drive 92 miles?</h3>
The first step is to determine the gallons needed to drive 1 mile. To do this, divide the 6 gallons by 138 miles. Division is the process of grouping a number into equal parts using another number. The sign used to denote division is ÷.
Gallons needed for 1 mile = 6/138
In order to determine the gallons needed for 92 miles, multiply the ratio gotten in the previous step by 92
(6/138) x 92 = 4 gallons
The option that gives 4 gallons is : 92 = 23g
g = 92 / 32 = 4
