In PEMDAS we do Multiplication and Addition in the same step ?

No

Step-by-step explanation:

Multiplication comes before addition and each letter of PEMDAS represents a step. Multiplication and addition are their own steps.

P-Parenthesis

E-Exponents

M-Multiplication

D-Division

A-Addition

S-Subtraction

y -5 = (-1/4)(x + 8)

step-by-step explanation:

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.
