3x - 4y = 8
y = mx + b ; m is the slope ; b is the y-intercept
-4y = -3x + 8
y = -3x/-4 + 8/-4
<span>y = 3/4 x - 2</span>
A short-cut to accurately evaluate the given expression above is using a scientific calculator where one can include integrals and evaluate using limits. In this case, using a calculator, the answer is equal to 0.2679. One can verify this by integrating truly letting 1-x^2 as u and use its du to be substituted in the numerator
Answer:
$75
Step-by-step explanation:
I just guessed numbers until 80% off a number hit 60 and that was 75
This is all if you don't solve as a quadratic equation.
Look at the other answer.
Answer:
<em><u>x = 9.75</u></em>
Step-by-step explanation:
Step 1. Distribute the 2(Do 2 times 2x and 2 tiems 5)
4x + 10 = 49
Step 2. Subtract 10 from both sides.
4x = 39
Step 3. Divide it all by 4 to isolate the variable.
x = 9.75
