Answer:
<h2>2.) When dividing by −2, he did not change the direction of the sign. </h2>
Step-by-step explanation:
-4(x + 8) ≤ -2x + 50 <em>use the distributive property: a(b + c) = ab + ac</em>
-4x - 32 ≤ -2x + 50 <em>add 2x to both sides</em>
-4x + 2x - 32 ≤ -2x + 2x + 50
-2x - 32 ≤ 50 <em>add 32 to both sides</em>
-2x - 32 + 32 ≤ +50 + 32
-2x ≤ 82 <em>divide both sides by (-2) / </em><em>flip the inequality sign</em><em>/</em>
x ≥ -41
Andrew's mistake:
2.) When dividing by −2, he did not change the direction of the sign.
Answer:
225
Step-by-step explanation:
the person chages 40 per hour with a one time service charge of 65. our equation is 40h+65 where h equal hours. the person spend 4 hour so the equation is (40x4)+65. 40x4 is 160. 160 + 65 is 225
Answer:
R = 0.8333%/month
(R = 9.9996%/year)
Equation:
r = (1/t)(A/P - 1)
Calculation:
Solving your equation:
r = (1/4)((8267.7/8001) - 1) = 0.00833333
r = 0.00833333
Converting r decimal to R a percentage
R = 0.00833333 * 100 = 0.8333%/month
Calculating the annual rate
0.8333%/month × 12 months/year = 9.9996%/year.
The interest rate required to get a total amount, principal plus interest, of $8,267.70 from simple interest on a principal of $8,001.00 over 0.333333 years (4 months) is 0.8333% per month.
Answer:
The distance from one base to the next is 90 ft. You can make a right triangle with two sides being 90 ft and the long side being the distance between home and second. Then you use the pythagorean theorem to find that distance.
90^2 + 90^2 = d^2
d = sqrt (16200) = 127.28 ft
Answer: g(x) -1/2fx-1
Step-by-step explanation: Pretty much you distribute the 1/2f to the x and the 2 then you got you function.
