Answer: 1/2a-4b
Step-by-step explanation:
When combining like terms you can only combine numbers with the same variables.
So we subtract 3/4a-1/4a=1/2a
And then we subtract the b values
2b-6b=-4b
1/2a-4b
Answer:
If the lines BC and DE are parallel, the value of c is c=-2
Step-by-step explanation:
We are given line segment BC with end points B(2, 2) and C(9,6) and line segment DE with endpoints D(c, -7) and E(5, -3).
Using slope formula: we can find point c
When 2 lines are parallel there slope is same.
So, Slope of line BC =Slope of Line DE
We have:
Putting values and finding c
So, If the lines BC and DE are parallel, the value of c is c=-2

Answer:
A Juan le quedan 45 empanadas.
Step-by-step explanation:
Dado que Juan vende 180 empanadas al día, y por la mañana vende las dos terceras partes y por la tarde la cuarta parte de lo que queda, para determinar cuántas empanadas le queda por vender en la noche se debe realizar el siguiente cálculo:
180 x 2 / 3 = 120
180 - 120 = 60
60 x 1/4 = 15
60 - 15 = 45
Por lo tanto, a Juan le quedan 45 empanadas.
D) y + 3 = -6(x + 9)
The equation for point-slope form is y - y1 = m(x - x1) where (x1, y1) is a point and m is the slope.
Substitute the values in to get y - (-3) = -6(x - (-9)).
Now, simplify a little bit.
y + 3 = -6(x + 9)
There’s the answer.
