Answer:
Step-by-step explanation:
Notice that the y-component is the same, -2, in these two points. That means y does not change as x changes, and therefore we conclude that the slope of the line connecting the two points is m = rise / run = 0.
-2 - (-2)
Alternatively, use m = -------------- = 0
3 - 13
The value of the slope in question is zero: m = 0
Answer:
k = 13The smallest zero or root is x = -10
===============================
note: you can write "x^2" to mean "x squared"
f(x) = x^2+3x-10
f(x+5) = (x+5)^2+3(x+5)-10 ... replace every x with x+5
f(x+5) = (x^2+10x+25)+3(x+5)-10
f(x+5) = x^2+10x+25+3x+15-10
f(x+5) = x^2+13x+30
Compare this with x^2+kx+30 and we see that k = 13
x^2+13x+30 = 0
(x+10)(x+3) = 0
x+10 = 0 or x+3 = 0
x = -10 or x = -3
The smallest zero is x = -10 as its the left-most value on a number line.
Step-by-step explanation: Hope this helps kind of.

Answer:
5f+10x+35
Step-by-step explanation:
5(7+f+2x)
=(5)(7+f+2x)
=(5)(7)+(5)(f)+(5)(2x)
=35+5f+10x
=5f+10x+35
lol college stuff looks hard:o
X = 2y + 8
x - y = 25
2y + 8 - y = 25
y = 25 - 8
y = 17
x = 2y + 8
x = 2(17) + 8
x = 34 + 8
x = 42
the larger number (x) = 42...and the smaller number (y) = 17
