Answer:
A real solution in algebra is simply a solution to an equation that is a real number.
for example
If y>0, then x2 = y has two real solution or roots. x = ±√y
If y=0, then x2 = y has one real solution.
Answer:
what
Step-by-step explanation:
Y=1-2x
-4x+3y=-17
Plug in y into -4x+3y=-17
-4x+3 (1-2x)=-17
-4x+3-6x=-17
-10x+3=-17
-3 both sides
-10x=-20
÷-10 both sides
x=2
plug in x to find y
y=1-2 (2)
y=1-4
y=-3
x+3y=9
2x+3y=15
make first equation into x= form
-3y both sides
x=-3y+9
2x+3y=15
plug in x into 2x+3y=15
2 (-3y+9)+3y=15
-6y+18+3y=15
-3y+18=15
-18 both sides
-3y=-3
÷-3 both sides
y=1
plug in y
x+3 (1)=9
x+3=9
-3 both sides
x=6
Answer:
Step-by-step explanation:
Given
Required
Determine the function
From the question, we have:
This is represented as:
or
If he spends 20 minutes on 1 figurine;
Multiply both sides by 3
This means that, he spends 60 minutes on 3
<em>plus he still has 9 left</em>
So, the initial figurines is:
or
So, we have:
and
Calculate the slope (m)
The equation is then calculated as;
To solve for c, we have:
So, we have:
Add 3 toboth sides
Hence, the equation is:
Answer:
1200
Step-by-step explanation:
If 24 is 2%, 100% would be 1200 because if you multiply 2 by 50 you get 100% so you multiply 24 by 50 which is 1200
