Step-by-step explanation:
4(4)+ 2(-5) = 6
16+ (-10) = 6
Answer:
1. y= 3x+7
2.y=1/2 x -1
Step-by-step explanation:
1.
Parallel lines have the same gradient.In the equation given,
y= 3x+5 , the slope is 3
So now, you find the equation of a line passing through point (-1,4) with m=3
m=Δ y/Δx
3= y-4/ x--1
3= y-4 /x+1
3(x+1) = y-4
3x+3 =y-4
3x+3+4=y
⇒⇒ y= 3x+7 is the equation.
2.
Two lines that are perpendicular to each other have the product of their slopes to be -1
Given equation to be y= -2x +8 then, m₁ = -2
Finding m₂ will be;
m₁ *m₂ = -1
-2 * m₂ = -1
-2 m₂ = -1
m₂ = -1/-2 = 1/2
So writing the equation of the perpendicular line with m₂ =1/2 , point (-4,-3)
will be;
m=Δy/Δx
1/2=y--3/x--4
1/2 = y+3/x+4
x+4 = 2( y+3)
x+4 = 2(y+3)
x+4 =2y+6
x+4-6=2y
x-2=2y
x/2 -2/2=y
y=1/2 x -1 is the equation.
Answer:
The seventh root of a^5
Step-by-step explanation:
is equal to
![\sqrt[7]{a^5}](https://tex.z-dn.net/?f=%5Csqrt%5B7%5D%7Ba%5E5%7D)
because
![b^{1/m} = \sqrt[m]{b}](https://tex.z-dn.net/?f=b%5E%7B1%2Fm%7D%20%3D%20%5Csqrt%5Bm%5D%7Bb%7D)
hope this makes sense and helps
Answer: 37
Step-by-step explanation:
-5x - 15 = - 200
-5x = -200 + 15
-5x = -185
x = 37
