Lets first number is x, so second number is (x+32).
The sum of these numbers is 186 so
x+(x+32)=186
2x+32=186
2x=154
x=77
second number is x+32=77+32=109
Answer: numbers are 77 and 109
Answer:
y = 11x
Step-by-step explanation:
We have two points so we can find the slope
(1,11) and (2,22)
m = (y2-y1)/ (x2-x1)
= (22-11)/(2-1)
= 11/1
The slope is 11
We can use the point slope form to get an equation
y-y1 = m(x-x1)
y-11 = 11(x-1)
Distribute the 11
y-11=11x -11
Add 11 to each side
y-11+11 = 11x-11+11
y = 11x
Answer:
x=√65 and x=-√65
Step-by-step explanation:
Givn the expression 2x^2 - 9 = 121
Add 9 to both sides
2x^2 - 9 + 9 = 121 + 9
2x^2 = 130
Divide both sides b 2
2x^2/2 = 130/2
x^2 = 65
x = ±√65
x=√65 and x=-√65
Answer:y
=
−
x
+
3
Explanation:
Slope intercept form can be represented as
y
=
m
x
+
b
To get an equation into this form, we should try to get
y
all alone.
From
y
+
x
=
3
we can subtract
x
from both sides
to get
⇒
y
=
−
x
+
3
which is now in slope intercept form :)
Step-by-step explanation:
Answer:
P = 4x - 2
Step-by-step explanation:
Perimeter is all the side lengths added together.
Step 1: Set up expression
P = 2x - 5 + 5 - x + 3x - 2
Step 2: Combine like terms
P = 4x - 2
