Answer:
The value of X is always 1
Answer:
D) 5
Step-by-step explanation:
Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Divide 2 from all terms within the equation:
(2y)/2 = (10x - 8)/2
y = (10x)/2 - (8)/2
y = 5x - 4
Note the slope-intercept form:
y = mx + b
y = y
x = x
m = slope
b = y-intercept.
In this case, 5 is in place of m, or your slope.
D) 5 is your answer.

Answer:
Alrighty! So this is what we know:
Slope (m) = (-4)
Co-ordinate (0,3)
Co-ordinate 2 (6,t)
t = ?
Let's find our equation...
y=mx+b <-- just plug what we know in...
3=(-4)0+b
3=0+b
b=3
We just found b! woohoo
Now what is t? t is a value we need to know WHICH IS the y value of a co-ordinate that corresponds to when x is 6, as we know a co-ordinate is expressed as --> (x value, y value).
SO-
t=y
plug it in our equation...
y=mx+b
t=(-4)x+3
t=(-4)(6)+3
t=(-24)+3
t=(-21)
SOOOOOOOO WE HAVE OUR T!! just write a therefore statement like "therefore the value of t is -21." and you're set! hope this helped, any questions? ask in the comment section. :)
Step-by-step explanation:
Answer:
17.
Step-by-step explanation:
f(x) = 2x^2 - 1
f(-3) = 2(-3)^2 - 1
= 2 * 9 - 1
= 18 - 1
= 17
Hope this helps!
