Answer:
Step-by-step explanation:
First, isolate the variables onto one side of the equation.
2x + 3 = x - 4
(subtract x)
x + 3 = -4
Then, remove any remaining numbers.
(subtract 3)
x = -7
I hope this helps!
5 for the first one and 7 for the second hope this helps
Answer:
Please restate your question.
It needs the y-intercept to be decipherable.
Step-by-step explanation:
A. <span>2x + 5y= 10
5y= -2x+10
</span>-> y= -2/5x+2
b. The slope is 2
c. For the y intecpet, x is always 0
y= -2/5x+2
y= -2/5(0)+2
y=0+2
y=2
(0,2) is the y-interecpt
d. Please veiw below
Surprise! It turns out that the answer is 1.
Why?!!??!
Notice this pattern when working with powers of 2:
2^0 2^1 2^2 2^3 2^4
? 2 4 8 16
Every time we increase the power we multiply by 2. Or reading the pattern backwards, every time we decrease the power we divide by 2. What is 2 divided by 2? It is 1! So 2^0 = 1 to finish the pattern:
2^0 2^1 2^2 2^3 2^4
1 2 4 8 16
Try it with 3 or with 5 or with any number! You'll see that the pattern holds!
