Y - y1 = m(x - x1)
slope(m) = 1...because a parallel line will have the same slope
(1,-5)...x1 = 1 and y1 = -5
now we sub
y - (-5) = 1(x - 1) =
y + 5 = 1(x - 1) <== u could leave that first " one " out if u want...
Answer:
Step-by-step explanation:
y - 3x = 18
To find the y- intercept let x = 0 in the equation and solve for y
y - 3(0) = 18
y - 0 = 18
y = 18 ⇒ (0,18 ) ← y - intercept
To find the x- intercept let y = 0 in the equation and solve for x
0 - 3x = 18
- 3x = 18 ( divide both sides by - 3 )
x = - 6 ⇒ (- 6, 0 ) ← x- intercept
Answer:
B=95°
E=95°
D=20°
C=65°
BC=7cm
Step-by-step explanation:
the triangles look like they are identical, just different in size only. Since DE= 15 and AB=10 that may mean that they have a 5cm difference making side BC= 7cm since EF= 12 minus 5 equals 7cm. Now for the other angles, a triangle no matter what,if we put all their angles together equal 180°. We already know angle A= 20 so the same applies to angle D. We also know that angle F=65 degrees, that makes angle C the same. The only thing that's left are angles B and E that can be found by adding our other angles. So if A+C(20+65)=85 then 180-85=95 degrees is angle B and since the triangles are identical the same goes to E.
Answer: (A) 2(x + 4)
Step-by-step explanation: We know that the measure of one side of the square is (x + 4). But, we first will need to find the total area and perimeter of the square in order to find the difference between them.
The area is length x width, so multiply 2(x + 4) Since all the sides are the same.
2(x + 4) = 2x + 8. The area is 2x + 8.
To find the perimeter simply add x + 4, four times. 4(x + 4).
4(x + 4) = 4x + 16 as the total perimeter of the square.
Now subtract the area from the perimeter.
4x + 16 - (2x + 8) --Distribute negative sign.
4x + 16 - 2x - 8 --Combine like terms
4x - 2x + 16 - 8
2x + 8.
2(x + 4) is equivalent to 2x + 8 and is therefore the answer.
Answer:
Shape 1 = l×b
= (6x²y) × (4y²)
Shape 2 = l×b
= (6x²y+2x²y)×(y²)
= (8x²y) × y²
