Icould really use some with this yall

1. when six is added to four times a number the result is 50. find the number.

2. the sum of a number and nine is multiplied by -2 and the answer is -8. find the number.

3. if four is subtracted from twice a number the result is 10 less than the number. find the number.

4. three times a number divided by two is a number divided by 4. find the number.

5. a number is added to two and the sum is that multiplied by three. that result is five less than the original integer. find the number.

1: 11

2: 13

Step-by-step explanation:

For 1

reverse the questions

50-6= 44

44 divided by 4 is 11

For 2

again, reverse

-8 divided by -2 is 4

4 + 9 is 13

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
