Answer:
y = 3x - 10
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 3 , thus
y = 3x + c ← is the partial equation
To find c substitute (1, - 7) into the partial equation
- 7 = 3 + c ⇒ c = - 7 - 3 = - 10
y = 3x - 10 ← equation of line

and B has coordinates (8,9).
Answer:
(5,6)
Step-by-step explanation:
Midpoint formula: (x1+x2/2 , y1+y2/2)
So you plug it in
your x's: 2 and 8
your y's: 3 and 12
(2+8/2 , 3+9/2)
(10/2 , 12/2)

Please help me Find X:
Answer:
x=50
Step-by-step explanation:
since all the angles of a triangle when added equal 180 we are going to have an equation like this:
180=102+28+x
180=130+x
so to find the value of x we have to subtract the final number by the value already given to us so something like:
180-130
which equals 50

Answer:
7 + 4[tex]\sqrt{3}[/tex]
Step-by-step explanation:
note that [tex]\sqrt{a}[/tex] × [tex]\sqrt{a}[/tex] = a
Given
(2 + [tex]\sqrt{3}[/tex] )² = (2 + [tex]\sqrt{3}[/tex] )(2 + [tex]\sqrt{3}[/tex] )
Each term in the second factor is multiplied by each term in the first factor, that is
2(2 + [tex]\sqrt{3}[/tex] ) + [tex]\sqrt{3}[/tex](2 + [tex]\sqrt{3}[/tex] ) ← distribute both parenthesis
= 4 + 2[tex]\sqrt{3}[/tex] + 2[tex]\sqrt{3}[/tex] + 3 ← collect like terms
= 7 + 4[tex]\sqrt{3}[/tex]

An object travels along a horizontal straight path at a constant rate. The object travels 1 20 20 1 of the length of the path in 3 4 4 3 second. At that rate, how many seconds does it take the object to travel the entire length of the path?
Answer:
the number of seconds that needed for the overall path length is 15 seconds
Step-by-step explanation:
The computation of the number of seconds that needed for the overall path length is shown below:
The tiny portion is 1 ÷ 20
And, the entire length is 20 ÷ 20
Now if 1 ÷ 20 is travelled in 3 ÷ 4 path so the time needed is
= 20 × 3 ÷ 4
= 15 seconds
Hence, the number of seconds that needed for the overall path length is 15 seconds

what is the answer for 96+2w = 2(80 - 3w) and whyy???
Answer:
w = 8
Step-by-step explanation:
96 + 2w = 160 - 6w
2w + 6w = 160 - 96
8w = 64
w= [tex]\frac{64}{8}[/tex] = 8
STE{ Answer:
w=
Step-by-step explanation:
96+2w=2(80-3w)
STEP 1 remove perentheses
96+2w=160-6w
STEP 2 take away the ws from one of the sides.
96+8w=160
STEP 3 subtract 96
8w=64
Step 4 divide
64/8
Step 5 get the answer
w=8

A set of speakers costs $22 and songs cost $1.25 each. The sales tax rate is 7.5%. The expression 0.075(22 + 1.25s) can be used to determine the amount of sales tax due on the entire purchase. Expand the expression and round to the nearest hundredth.
Answer:
1.65 + 0.09s
Step-by-step explanation:
Cost of speaker = 22
Cost per song = $1.25
Sales tax = 7.5%
Sales tax due on entire purchase :
0.075(22 + 1.25s)
1.65 + 0.09375s
To the nearest hundredth :
1.65 + 0.09s
