Answer:
slope= 3/2
Step-by-step explanation:
First, isolate y in 7x-y=29 because 1 is y's coefficient.
7x-y=29
-y=29-7x
y=7x-29
Now, substitute 7x-29 for y in 7x+8y=20.
7x+8y=20
7x+8(7x-29)=20
7x+56x-232=20
Add all coefficients.
63x-232=20
Isolate x by adding 232 to both sides.
63x-232=20
63x=252
x=4
Now, substitute 4 for x in your first equation.
y=7x-29
y=7(4)-29
y=28-29
y=-1
Your answer would be (4,-1).

Answer:
1×10^8
Step-by-step explanation:
First, multiply 1 million by 100 because 1 dollar is worth one hundred pennies. In total, it takes 100000000 pennies for 1 million dollars. Then, because there are 8 zeros, it would be 1 times 10 to the 8th power.
