Find the slope <br> (-6,2) (4,5)

Misha Larkins [42]

Slope: $3/10$

<u>Use the slope formula</u>

$y_{2}-y_{1}/x_{2}-x_{1}\\5-2/4--6\\=3/10$

<u>Note</u>

<u></u> $(x_{1},y_{1})=(-6,2)\\(x_{2},y_{1}=(4,5)$ <u></u>

Which facts could be applied to simplify this expression? Check all that apply.

kykrilka [37]

The answer is B, C, and D. Like terms are terms with all the same variable, so 5x and -x are like terms.

C is correct. If we add -x to 5x, we get 4x. The other numbers remain unchanged because they have no like terms.

D is correct. Applying the rule of like terms, which is that like terms are numbers with the same variable, only add together numbers with the same variable.

Hope this helps!

How to solve 10 + (2 × 3)^2 ÷ 4 × (1/2)^3

BlackZzzverrR [31]

Answer:

<h2>11.125</h2>

Step-by-step explanation:

$10 + {(2 \times 3)}^{2} \div 4 \times {( \frac{1}{2}) }^{3}$

To raise a product to a power, raise each factor to that power

$= 10 + 4 \times 9 \div 4 \times {( \frac{1}{2} )}^{3}$

To raise a fraction to a power, raise the numerator and denominator to that power

$= 10 + 4 \times 9 \div 4 \times \frac{1}{8}$

Any expression divided by itself equals 1

$= 10 + 1 \times 9 \times \frac{1}{8}$

Any expression multiplied by 1 remains the same

$= 10 + 9 \times \frac{1}{8}$

Calculate the product

$= 10 + \frac{9}{8}$

Write all numerators above the common denominator

$= \frac{80 + 9}{8}$

Add the numbers

$= \frac{89}{8}$

Divide

$= 11.125$

Hope this helps..

Best regards!!
