The answer is b, or 84ft squared. To find the area of a rectangle, you multiple the length by the width. So you multiply 10.5 by 8, which equals 84.
Yo sup??
4x+5y=-9
y=(-4x)/5-9/5
we see that this is of the form y=mx+c
where m is the slope
therefore the slope of the line is -4/5
To find y intercept, put x=0
y=-4*0/5-9/5
y=-9/5
Therefore y intercept is -9/5
Hope this helps.
Answer:
first you would find the sum of all the people who DONT have grey hair (15)
5:15 or if simplified it would be 1:3 pls mark brainliest if correct :D
Answer:
Step-by-step explanation:
6root = 6^2= 6 x 6
= 36
6root7 = 36 x 7 = 252
Also,
5xroot7 = 5 x 7^7
= 5 x 49
= 245
Therefore,
6root7 - 5xroot7 - Xroot7 = 0
252 - 245 - 7x^2
= 7- 7x^2
5x - 20y = 60...reduce by dividing by 5
x - 4y = 12
this is the same as the other equation....therefore, it is the same line...meaning infinite solutions
=============
y - 7x = -14
y = 7x - 14.....slope = 7, y int = -14
7y - 49x = -2
7y = 49x - 2
y = 7x - 2/7.....slope is 7, y int is -2/7
if the slopes are the same, but the y int are different, then u have a parallel lines with no solutions
