U(x)=-2-2x+7 please help

1 answer:

4 0

<span>Simplifying u(x) = -2 + -2x + 7 Multiply u * x ux = -2 + -2x + 7 Reorder the terms: ux = -2 + 7 + -2x Combine like terms: -2 + 7 = 5 ux = 5 + -2x Solving ux = 5 + -2x Solving for variable 'u'. Move all terms containing u to the left, all other terms to the right. Divide each side by 'x'. u = 5x-1 + -2 Simplifying u = 5x-1 + -2 Reorder the terms: u = -2 + 5x-1</span>

Evaluate quantity the square root of 36 times 3 squared minus the cube root of negative 64 end quantity divided by 2 squared.

abruzzese [7]

$\cfrac{\sqrt{36}\cdot 3^2-\sqrt[3]{-64}}{2^2}\implies \cfrac{\sqrt{6^2}\cdot 3^2-\sqrt[3]{(-4)^3}}{2^2}\implies \cfrac{6\cdot 3^2-(-4)}{2^2} \\\\\\ \cfrac{6\cdot 9-(-4)}{4}\implies \cfrac{54-(-4)}{4}\implies \cfrac{54+4}{4}\implies \cfrac{58}{4}$

notice, PEMDAS

groups first, then Exponents, then Multiplication and Division from left-to-right, then Addition and Subtraction from left-to-right last.

Two factors are multiplied and their product it 34.44. One factor is a whole number. What is the least number of decimal places

Tanya [424]

The answer is 2, because if a number is a whole number, for example 2, you must multiply it by a number with 2 decimals, in this case 17.77, to get 34.44 based on this example.

*There are some cases where this doesn't apply, I think, but it does apply for your question.
