-2(4x-1)=5+7
(4x-1)=12/-2
4x=-6+1
x=-5/4
Answer:
Written out the equation would look like f(x) = 55(1.06)^x
The graph would look something like the attached picture. (It intercepts with the y-axis at 55).
Answer:
No, it's not
Step-by-step explanation:
2x3=6. So the Greatest Common Factor (GCF) is 6
0.19 for one cookie and 0.59 for one doughnut
x for how much one cookie costs and y for how much one doughnut costs
6x+4y=3.5
12x+5y=5.23
solve by substitution: (elimination would work too)
4y=3.5-6x
y=0.875-1.5x
12x+5(0.875-1.5x)=5.23
12x+4.375x-7.5x=5.23
4.5x=0.855
x=0.19
now use x to solve for y:
6(0.19)+4y=3.5
1.14+4y=3.5
2.36=4y
y=0.59
Check the work: 6(0.19)+4(0.59)=3.5
