Answer:
- Infinitely many solutions
Step-by-step explanation:
- 3(x + 10) + 6 = 3(x + 12)
- 3x + 30 + 6 = 3x + 36
- 3x - 3x = 36 - 36
- 0 = 0
This equation has infinitely many solutions as for any value of x we have same result
The graph if g(x) is vertically stretched by a factor of 3
Hope this helped :)
I’m pretty sure I did my math right, hope this helps.
Answer:
Midpoint( .5,-2.5)
Step-by-step explanation:
To find the midpoint, add the x coordinates and divide by 2 and then add the y coordinates and divide by 2
x: (-1+2)/2 = 1/2=.5
y: (-9+4)/2 = -5/2 = -2.5
Midpoint( .5,-2.5)
<u>Answer</u>:
x = 7, y = 2
<u>Explanation</u>:
equations given:
x + 7y = 21
x + 4y = 15
make "x" the subject:
x + 7y = 21
x = 21 - 7y .........equation 1
x + 4y = 15
x = 15 - 4y .......equation 2
Solving both the equations simultaneously:
15 - 4y = 21 - 7y
-4y + 7y = 21 - 15
3y = 6
y = 6 ÷ 3
y = 2
If y is 2
Then x = 21 -7y;
x = 21 - 7(2)
x = 21 - 14
x = 7
