write an equations in slope-intercept form of the line that passes through the point(5,9) with slope 7

vovangra [49]

Answer:

$y=7x-26$

Step-by-step explanation:

1) Write it in the slope-intercept form of $y=mx+b$ , where m is the slope and b is the y-intercept.

$y=7x +c$

2) Substitute the given coordinates into $y=7x +b$ , and then solve for c.

$9=7(5) +b\\9=35+b\\9-35=b\\b= -26$

3) Substitute c into $y=7x +b$

$y=7x-26$

Therefore, the answer is $y=7x-26$ .

A chef uses 3 3/4 pounds of semolina flour and 1 5/8 pounds whole wheat flour for each batch of pasta she makes. One week she us

atroni [7]

One batch = 3 3/4 + 1 5/8
one batch = 3 6/8 + 1 5/8
one batch = 4 11/8
one batch = 5 3/8 pound of flour

One week = 86 pound
86 ÷  5 3/8 = 86 ÷   43/8
86 ÷  5 3/8 = 86 x   8/43
86 ÷  5 3/8 =16

She makes 16 batches of pasta
