Answer:
x=0, y = 3/2
Step-by-step explanation:
Ok, for substitution, you need to solve for y in terms of x, I'll do this for the first eqyation
8y=-7x+12
y=-7/8x+3/2, now plug in y in the second equation
-4x+2(-7/8x+3/2)=3, solve for x now
-4x-7/4x+3=3,
-4x-7/4x=0, x=0 now plug in 0 for either equation to solve for y
-4(0)+2y=3
2y=3, y=3/2
Answer:
f(-3)=3
Step-by-step explanation:
We know that f(x)=-2x-3. In order to find f(-3), we simply need to substitute x with -3.
Thus, we have:
=-2(-3)-3
=6-3
=3
Answer:
4,415.1515...
Step-by-step explanation:
To find the value of the number that 1457 is 33% of, we can change the percentage into a decimal then divide.
33% = 0.33
1457 / 0.33 = 4,415.1515...
Best of Luck!
