Answer:
1.y=3x+1
2.y=1/3x+2
3.y=-2x+5
4.y=4x
5.y=4x-4
6.y=-2x-5
Step-by-step explanation:
(i)
y=mx+c
10=(m)3+1
10=3m+1
10-1=3m
m =3
y=3x+1
And so on...
Answer:
Step-by-step explanation:
(x - 5)(x-4)
= x(x) - 4(x) - 5(x) - 4(-5)
= x^2 - 4x - 5x + 20
= x^2 - 9x + 20
Answer:
255
Step-by-step explanation:
254.95
.95 is closest to 255.
254.95...255.
Answer:
y = 
x + 2
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 )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (0, 2) and (x₂, y₂ ) = (3, 4)
m = 
=
The line crosses the y- axis at (0, 2) ⇒ c = 2
y = x + 2 ← equation of line
Answer:
-1, -12
Step-by-step explanation:
you take b which is 6 and make it negative, then you take a and multiply it by 2, which is 6. you then take the 2 numbers and put the -b over 2a in this formula -b/2a giving you -1 as your x value
after you do that, you input the -1 into the equation as x and the value you get out of that (-12) is the y value of the vertex
