Answer:
this is the correct answer
Step-by-step explanation:
y-7=4(x-2)
we need to simplify the y to het a
y-7=4x-8 (i did 4x-8 because of 4(x-2)
now y= 4x-8+(-7)
after calculating -8+(-7) IT becomes
y=4x-15
okay we have the guide Line
y=4x-15
the a is 4
because
a = {y=a.x+b}
now we need to find the points using this guide Line
y=4x-15
x= 2(you can add any number here ,we Just need to know where the point is )
y= 4(2)-15
y=8-15
y= -7
points are (2,7)
Answer:
A) ![g(x)=\sqrt[3]{x+4}+3](https://tex.z-dn.net/?f=g%28x%29%3D%5Csqrt%5B3%5D%7Bx%2B4%7D%2B3)
Step-by-step explanation:
The transformation that occured in the graph is that the function went up 3 and left 4. Algebraically, this would be ![g(x)=\sqrt[3]{x+4}+3](https://tex.z-dn.net/?f=g%28x%29%3D%5Csqrt%5B3%5D%7Bx%2B4%7D%2B3)
Answer:
A) x=9, x=-2, x=2
Step-by-step explanation:
(x-9)(x+2)(x-2)=0
x-9=0
x+2=0
x-2=0
x=9, x=-2, x=2
Answer:
y = -
x + 9
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 2x - 3 ← is in slope- intercept form
with slope m = 2
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
, thus
y = -
x + c ← is the partial equation
To find c substitute (8, 5) into the partial equation
5 = - 4 + c ⇒ c = 5 + 4 = 9
y = -
x + 9 ← equation of line
