Answer:
Step-by-step explanation:
First we need to rewrite 3x-5y=8 in slope-intercept form.
The slope of this line is
The line perpendicular to this line will have a slope that is the negative reciprocal of 3/5, which is
This line passes through (3,7).
The equation is given by:
We substitute the point and slope to get:
We multiply through by 3 to get:
Expand to obtain:
The equation is $130 + $31.67x = 500
Subtract 130 from both sides $31.67x = $370
Divide $31.67 from both sides
X=11.68
BUT
you can’t have .68 of a day so the answer is 11 days.
Answer: The square root of 8 is expressed as √8 in the radical form and as (8)½ or (8)0.5 in the exponent form. The square root of 8 rounded up to 8 decimal places is 2.82842712. It is the positive solution of the equation x2 = 8.

Answer:
Step-by-step explanation:
She has 50$. A jacket is on for 48.20$. The tax is 6% of the product you buy.
6% = 0.06
To find 6% you do:
0.06*48.20
Which is 2.892.
You ADD 2.892 to the price.
48.20+2.892=
51.092. Round it:
51.09 > 50.00
No, she does not have enough.
Answer:
59 yards
Step-by-step explanation:
