Answer:
y = -2x+7
Step-by-step explanation:
The slope intercept form of a line is
y = mx+b where m is the slope and b is the y intercept
y = -2x+b
Using the point
3 = -2(2)+b
3 = -4+b
3+4 = b
7=b
y = -2x+7
Answer:
The coefficient of x² in the expression is 2
x/3(6x-1/2) = 6x²/3 - x/6
= 2x² - x/6

Answer:
Both Tom and Jerry will apart 176 miles in 2 hours .
Step-by-step explanation:
Given as:
Tom and Jerry moves in opposite direction
The speed of Tom = 38 mph
The speed of Jerry = 50 mph
Let The distance cover by Tom = x mile
The distance cover by Tom = ( 176 - x ) miles
Time taken by both are same = T hour
![\textrm(Time) = \dfrac{\textrm(Distance)}{\textrm(Speed)}](https://tex.z-dn.net/?f=%5Ctextrm%28Time%29%20%3D%20%5Cdfrac%7B%5Ctextrm%28Distance%29%7D%7B%5Ctextrm%28Speed%29%7D)
Or, Time taken by Tom
T =
... 1
∴ x = 38 T
And Time taken by Jerry
![\textrm(T) = \dfrac{\textrm(Distance)}{\textrm(Speed)}](https://tex.z-dn.net/?f=%5Ctextrm%28T%29%20%3D%20%5Cdfrac%7B%5Ctextrm%28Distance%29%7D%7B%5Ctextrm%28Speed%29%7D)
Or, T =
So , put the value of T from 1
=
Or, 50 × x = ( 176 - x ) × 38
So 50 x + 38 x = 6688
Or, 88 x = 6688
∴ x =
= 76 mile
So, From, eq 1
T =
or, T =
= 2 hours
Hence both Tom and Jerry will apart 176 miles in 2 hours . Answer
A triangle has angles of 3x, 7x, and 8x that add up to 180
3x + 7x + 8x = 180
combine like terms
18x = 180
Divide both sides by 18
x = 10
Angle 3x = 3(10) = 30
Angle 7x = 7(10) = 70
Angle 8x = 8(10) = 80
Follow PEMDAS
5^3 = 5 x 5 x 5
5 x 5 x 5 = 125
125^3 = 125 x 125 x 125
125 x 125 x 125 = 1,953,125
1,953,125 is your answer
