The Answer is C since Y is for the miles and X for hours, we need to substitute the miles in the y variable and solve for X !!

Given is a table of Time(hours)-Distance(miles).

We have points (4, 208), (6, 312), (8, 416), (10, 520).

<u>Finding slope of given points:-</u>

m_1=\frac{312-208}{6-4}= \frac{104}{2}=52 \\m_2=\frac{416-312}{8-6}= \frac{104}{2}=52 \\m_3=\frac{520-416}{10-8}= \frac{104}{2}=52

We know general equation of the line is given by y = mx+b.

<u>Using point (4, 208) and slope m = 52 in the equation y = mx+b.</u>

208 = (52)(4) + b

208 = 208 + b

b = 0.

So, the equation is y = 52x.

What is the difference between lcm and gcf and all of that help im doing it on my home work pls help i hate this stuff best answ
raketka [301]

greatest common factor=gcf

least common multule=lcm

with 12 and 16

factors of 12=2 times 2 times 3

factors of 16=2 times 2 times 2 times 2

greates common factor is 2 times 2=4

least common multiple means all factors combined minus repeats or 2 times 2 times 2 times 2 time 3=48

Area of a triangle is given by the formula A=1/2 bh. The area of the triangle shown to the right is 56 sq. units. Find its base
Westkost [7]
Given

base=2x+6
height=x+4

and
area=56 square units

56=1/2 times (2x+6) times (x+4)
times bot sides by 2
112=(2x+6)(x+4)
expand
112=2x²+14x+24
divide both sides by 2
56=x²+7x+12
minus 56 both sides
0=x²+7x-44
factor
waht 2 numbers mulitply to get -44 and add to get 7
11 and -4
0=(x-4)(x+11)
set to 0

x-4=0
x=4

x+11=0
x=-11
false, measures can't be negative

x=4


height=x+4
height=4+4=8


base=2x+6
base=2(4)+6=8+6=14



x=4 and base=14 and height=8

A+44=B<br> A=1x+76<br> B=-6x+134 <br> What is the value of A?
Rashid [163]
Hi there! A = 78

A + 44 = B
We can plug in the values of A and B into the equation. We then get an equation with only one variable (x), which we can solve.

1x + 76 + 44 = - 6x + 134
Collect terms.

1x + 120 = - 6x + 134
Add 6x to both sides.

7x + 120 = 134
Subtract 120 from both sides

7x = 14
Divide both sides by 7

x = 14 / 7 = 2

A = 1x + 76
Now plug in the value of x we just found

A = 2 + 76 = 78
