Answer:
Intergers
Step-by-step explanation:
A subset is a part of a whole math concept, idea, or sample space.
We need to find what math concept -5 is apart of.
-5 is part of the All Real Numbers section.
-5 is also part of integers as well.
Answer:
m = 2.25
Step-by-step explanation:
In a standard equation of y = mx + b, m is the slope. In this situation, the slope is the price paid per mile.
To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁). I will use the points (3, 8.25) & (11, 26.25)
Plug in these values:
(26.25 - 8.25) / (11 - 3)
Simplify the parentheses.
= (18) / (8)
Simplify the fraction.
18/8
= 9/4
This is your slope.
In a dollar value, it is 9/4 of a dollar, or $2.25 per mile.
Answer:
x = 2
Step-by-step explanation:
How to find "x"
3x = 4 + 2(3 - x) *Remove the parentheses*
3x = 4 + 6 - 2x *Calculate*
3x = 10 - 2x *Move the variable to the left*
3x + 2x = 10 *Collect the terms*
5x = 10 *Divide both sides*
x = 2
I hope the helped!!!
Answer:
(x, y) = (-4, -15)
Step-by-step explanation:
You can equate the expressions for y and solve for x.
3/4x -12 = -4x -31
Adding 4x+12 gives ...
(4 3/4)x = -19
(19/4)x = -19
Multiplying by 4/19, we find ...
x = -4
Substituting that into the first equation, we can find y:
y = (3/4)(-4) -12 = -15
The solution is (x, y) = (-4, -15).
2l+2w=perimeter <= equation for perimeter
<span>w+4=l <=length is 4 greater than width </span>
<span>2w+2(w+4)=24 <= plug in the l in the first equation with the second equation </span>
<span>2w+2w+8=24 <= solve the equation </span>
<span>4w=16 </span>
<span>w=4 </span>
<span>and, since </span>
