Answer:
we have two solution x = 5 and x = 11
but in given problem x = 5 and x = –11
thus, only one of his solution x = 5 is correct
Step-by-step explanation:
Given
–2|8 – x| – 6 = –12
adding 6 both sides
–2|8 – x| – 6 +6= –12 +6
–2|8 – x| = –6
dividing both side by -2
–2|8 – x| /-2 = –6/-2
=>|8 – x| = 3
we know that
in modulus function |Y| = -y or y
Thus
|8 – x| = 3
can be written as
8-x = 3 or 8- x = -3
8-x-3 = 0 or 8-x+3 = 0
5-x = 0 or 11 -x = 0
x = 5 or x = 11
thus, we have two solution x = 5 and x = 11
but in given problem x = 5 and x = –11
thus, only one of his solution x = 5 is correct

First we need to find the slope:
Slope formula=

Plug in your given values from the coordinate
Slope =

When we have 2 "-"'s together they turn into a + sign so we add.
Slope =

Slope =

Simplify (in this case divide) the slope:
Slope =

slope-intercept form is:
y=mx+b
Where m=slope
b=y-intercept
So far we have:
y=2x+b
To find b all we have to do is pick any given coordinate and plug it in:
I chose (3,1)
so we plug that in the equation
1=6+b
Now solve for b:
1=6+b
subtract 6 from both sides
b=-5
Final answer:
y=2x-5 (D)
Answer:
3/4=0.75
4/5=0.8
7/10=0.7
0.75+0.8=1.55
1.55-0.7=0.85
Step-by-step explanation:
Answer:
a is greater than or equal to 140
Step-by-step explanation:
Multiply both sides by 7, which cancels out the 7 and turns 20 into 140
