Answer:
it is 1
Step-by-step explanation:
17) you need to use the distance formula. the answer would be 146 (under a radical) or approximately 12.083
18) i’m pretty sure you’d use the side angle side (SAS) rule.
Answer:
-27
Step-by-step explanation:
Number be x
Eight added to number: x+8
sum is doubled: 2*(x + 8)
-11 less than number: x -11
2*(x + 8) = x -11
2*x + 2*8 = x - 11
2x + 16 = x - 11
2x - x = -11 -16
x = -27
The x-intercept also known as the root of a quadratic can be found by solving the equation with respect to x.
III is the most useful for finding the roots
you would simply equate each term to
So y= x + 6 AND y= x - 8
0= x + 6 0= x - 8
x= -6 x= 8
: . x-intercepts are x= -6 & x= 8
Answer:
2x+7y>=10
Replace x and y with 2 and 1
2*2+7*1>=10
2*2=4
7*1=7
4+7>=10
7+4=11
2x+7y>=10 is a true statement
Because 11 is greater than 10 and it doesnt have to be equal to 10 as long as its greater.
