Answer:
Y = -4.5x
Step-by-step explanation:
First evaluate: -16x to the second power = -256x
Then add like terms: -256x + 238x = -18x
Then divide both sides by -18: -18x divided by -18/ 81 divided by -18
Which leaves you with y = -4.5x
Answer:
−1.13348172≤x≤1.13348172
Step-by-step explanation:
For this problem
Add −5x2 to both sides of the inequality.
−x16 + 1 + 5x2≥0
Convert inequality to an equation.
−x16 + 1 + 5x2 = 0
Factor −x16 + 1 + 5x2
Set the factor equal to 00.
x16−5x2−1 = 0
x≈ − 1.13348172,1.13348172
so,
x≤ − 1,13348172
−1.13348172≤x≤1.13348172
x≥1.13348172
−1.13348172≤x≤1.13348172
Answer:
<h2>From our analysis stores B has the better buy </h2>
Step-by-step explanation:
Hey there!!!
In this problem, to know actually the store that has the better buy we need to solve for the cost of 1 foot of sandwich from individual stores.
Stores A
if 5 foot cost $42.50
1 foot will cost x
cross multiplying
x= x= $42.50/5
x= $8.5
Stores B
if 6 foot cost $49.50
1 foot will cost x
cross multiplying
x= x= $49.50/6
x= $8.24
<em>From our analysis stores B has the better buy</em>
