Answer: x=-35/10
y=-4
Step-by-step explanation:
y = 3/2x +5/4
-2x+8y=-25
--------------------
replace y in second equation with: y = 3/2x +5/4
-2x+8(3/2x+5/4)= -25
-2x+12x+10= -25
10x=-35
x=-35/10
x=-3.5
7+8y= -25
8y=-32
y=-4
Answer:
q = 14
General Formulas and Concepts:
- Order of Operations: BPEMDAS
- Equality Properties
- Complementary Angles: Angles that add up to 90°
Step-by-step explanation:
<u>Step 1: Set up equation</u>
<em>The 2 angles must add up to 90°.</em>
(4q - 5)° + 39° = 90°
<u>Step 2: Solve for </u><u><em>q</em></u>
- Combine like terms: 4q + 34 = 90
- Subtract 34 on both sides: 4q = 56
- Divide both sides by 4: q = 14
Answer:
slope = 2/3
Step-by-step explanation:
Answer: 
Step-by-step explanation:
By definition the domain of an inverse function
is the range of f(x) and the range of the inverse function is equal to the domain of the principal function f(x).
If you have a function
, then to find the inverse function, follow these steps:
1. Make 


2. Solve for the variable "x":

3. Exchange the variable "x" with the variable "y":

4. Exchange "y" with
. Then the inverse function is:

Answer:
-1 to the nearest whole number.
Step-by-step explanation:
(-0.3) ÷ (-0.2)+(-2.56)
Order of operations - the division is done first:
= 1.5 = (-2.56)
= 1.5 - 2.56
= -1.06.
