A hardware store sells 2 gallons of paint and a paintbrush for a total of 845. Last year, Katy bought 4 gallons of paint and a paintbrush in order to paint her porch and paid a total of $85. The system of equations below represents this relationship,

2xy-45

try-95

This year, Katy needs to paint a shed, so she buys more paint and paintbrushes. She replaces the equation Ary-85 with the equation 6x +2y-130, which is the sum of Ary-85 and 2x + y - 45.

Determine whether each statement below is true. Select Yes or No for each statement

True False

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3

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.

just pick what you think i need more time let me know if this
