I think you meant simplify
Remove parentheses
5x*2+3x+4-2x*2+5x-1
Multiply the variables
10x+3x+4-4x+5x-1
Combine the variables
14x+4-1
Subtract
14x+3
2y = 8x + 6
y = 4x + 3
The graph is a straight line passing through points (0, 3) and (-3/4, 0) with slope = 4.
Point R is the midpoint of FE¯¯¯¯¯ , so the coordinates of point R are (3a, b).
In △DEF , the length of the base, DF¯¯¯¯¯ , is
4a, and the height is 2b, so its area is
1/2×4a×2b = 4ab.
In △QRP , the length of the base, QR¯¯¯¯¯ , is
3a-a = 2a, and the height is b, so its area is 1/2×2a×b = ab .
Comparing the expressions for the areas proves that the area of the triangle created by joining the midpoints of an isosceles triangle is one-fourth the area of the larger isosceles triangle.
Answer:
p - 0.05p
Step-by-step explanation:
The price of the car is p.
You must subtract from p the amount of 5% of p.
5% of p = 5% * p = 0.05p
5% of p is the same as 0.05p.
Now we subtract 0.05p from p.
p - 0.05p
Answer:
x-intercept: x = -4/3
Step-by-step explanation:
x-intercept when y = 0
-6x + 0 = 8
so
-6x = 8
x = 8/-6
x = -4/3
