3(-3 + 7x) ≤ -93

-3 + 7x ≤ -31

7x ≤ -28

x ≤ -4

Answer: x ≤ -4

-6(1 + 8x) ≥ 138

Multiplying or dividing both sides by a negative number flips the sense of the inequality.

1 + 8x ≤ 138/(-6) = -23

8x ≤ -24

x ≤ -24/8

Answer: x ≤ -3

7(6x - 4) ≥ 6x - 28

42x - 28 ≥ 6x - 28

36x ≥ 0

x ≥ 0

Answer: x ≥ 0

86 ≤ -4(1 - 5x) - 2x

86 ≤ -4 + 20x - 2x

90 ≤ 18x

5 ≤ x

Answer: x ≥ 5

Talja [164]

The average is found by adding all the temperatures together, then dividing by the number of days.

Since the average for five days was 63, then the total of the temperatures need to equal 63 x 5 = 315.


The total for the first four days was : 56 + 60 + 79 + 70 = 265


The fifth day is  315 - 265 = 50 degrees.

neonofarm [45]
\text{The formula of a slope:}\ m=\dfrac{y_2-y_1}{x_2-x_1}\\\\\text{We have:}\\C(3;\ -5)\to x_1=3;\ y_1=-5\\D(6;\ 0)\to x_2=6;\ y_2=0\\\\\text{substitute}\\\\m=\dfrac{0-(-5)}{6-3}=\dfrac{5}{3}\\\\\text{The point-slope formula:}\ y-y_1=m(x-x_1)\\\\\text{substitute}\\\\y-(-5)=\dfrac{5}{3}(x-3)\\\\y+5=\dfrac{5}{3}x-5\ \ \ |-5\\\\\boxed{y=\dfrac{5}{3}x-10}
