Put them in y= mx+b format. .
x+y=3 ---> y= -x+3
x-y=1 ---> y= x-1
The x's are your slope and the numbers are your y-intercept.
Hope it helps!
Answer:
1,25%
Step-by-step explanation:
Aby policzyć stopę procentową należy wykorzystać podzielić otrzymany zarobek (125$) przez kwotę zainwestowaną (10.000$) a następnie pomnożyć przez 100, aby otrzymać wartość wyrażoną w procentach.
I tak mamy
x 100 [%] = 1,25%
This is the following way to solve this problem:
3x-10(x+2)=13-7x
3x-10x-20=13-7x (multiply 10 times what's in the parentheses)
-7x-20=13-7x ( subtract 3x from -10x)
-7x-20-13=-7x ( since the 13 is positive, when we move it to the other
side, we change it's sign, so now we subtract 13 from 20
-7x-7=-7x
-7=-7x+7x ( we do the same thing we did above, now with the -7x)
-7=x
x=-7
Answer: x = -7

A .32 of people who support it are Democrats and .68 of people who support it are Republicans, so of the people who support it a larger percent are Republicans
Step-by-step explanation:
step 1. what is the question? probably solve for x. okay.
step 2. 4^(2x) + 1 = 4
step 3. 4^(2x) = 3 subtract 1 from each side
step 4. ln4^(2x) = ln3 take on of each side
step 5. 2xln4 = ln3 definition of logs
step 6. 2x = ln3/ln4 divide both sides by ln4
step 7. x = ln3/2ln2^2 divide both side by 2 and replace 4 with 2^2
step 8. x = ln3/4ln2.
