Right now the equations are in standard form, which is ax+by=c. You need to put them in the form y=x and then divide the equations by 3 since y itself is being multiplied by 3. And then graph them as you normally would
Hope this helps!
Step-by-step explanation:
4x+5y=4 (equation 1)
2x-y=9 (equation2)
solving equation 1 and 2 and multiplying equation 2 by 2
4x+5y=4
4x-2y=18
- + -
________
7y= -14
y= -2
putting the value of y in equation 2
2x-y=9
2x+2=9
2x=7
x=3.5
Answer:
Hi, this question is a little unclear. If you want to know what percentage he saved, it would be 30%, and to convert that percentage into a decimal would be a decimal of 0.30
F(-4)=G(-4) because when the two lines cross over the f line is at the -4 and same with G
