7
Step-by-step explanation:
Answer:
She didn't put the sign's in the proper place, it should be ( x + 3 ) ( x - 7 )
Step-by-step explanation:
( x - 3 ) ( x + 7 ) = x² + 7x - 3x - 21 = x² + 4x - 21
( x + 3 ) ( x - 7 ) = x² - 7x + 3x - 21 = x² - 4x - 21
Answer:
Step-by-step explanation:
Lets pick to columns in the table
Lets so (6,228) and (7,266)
To find the slope you need to do y1-y2/x1-x2
7-6/266-228=1/38.
1/38 is the slope.
y=1/38x+b
to find B you have to plug any of the y with the corresponding x values back in and solve for b.
Lets choose 228.
228=1/38(6)+b
228=6/28+b
(28/6)(228)=b
b=1064
the equation will be y=1/38x+1064
He spends $625. 25 percent equals 1/4. If you divide 2500 divided by 4 is 625.
