A football team gained 5 yards, lost 8 yards, lost another 2 yards, and then gained 45 yards. What were the total yards gained o

r lost? Explain your reasoning. Wouldn’t the answer be 40, because you have to subtract and add?

What's the answer to this question= 4(3x + 2) + 2(x + 3)

Serga [27]

Answer:

$\huge{ \boxed{ \bold{ \tt{14x + 14}}}}$

Option E is the best choice.

▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁

☯ Question : Simplify

4 ( 3x + 2 ) + 2 ( x + 3 )

☯ Available options :

☐ 12x + 16

☐ 24x + 48

☐ 10x + 2

☐ 14x + 48

☑ 14x + 14

☐ 9x + 5

✎ Step - by - step explanation :

$\sf{4(3x + 2) + 2(x + 3)}$

Distribute 4 through the parentheses

$\dashrightarrow{ \sf{12x + 8 + 2(x + 3)}}$

Distribute 2 through the parentheses

$\dashrightarrow{ \sf{12x + 8 + 2x + 6}}$

Combine like terms. Only coefficients of like terms can be added or subtracted

$\dashrightarrow{ \sf{12x + 2x + 8 + 6}}$

$\dashrightarrow{ \sf{14x + 8 + 6}}$

Add the numbers : 8 and 6

$\dashrightarrow{ \boxed{ \sf{14x + 14}}}$

Hope I helped!

Have a wonderful time ツ

I need help ASAP!!

Suggestion:

The width is the x value and the hight is the y value.

Plot the points on the graph as decimal if that helps.

The point at the bottom left is the origin (0,0)

I hope this helps.

Given the center and radius of a circle, write the equation of the circle.

Mashutka [201]

Answer:

(x + 2)² + (y - 1)² = 25

General Formulas and Concepts:

<u>Algebra I</u>

Coordinates (x, y)

<u>Pre-Calc</u>

Circle Center Formula: (x - h)² + (y - k)² = r²

<em>(h, k)</em> is center
<em>r</em> is radius

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify variables</em>

<em>(h, k)</em> = (-2, 1)

<em>r</em> = 5

<u>Step 2: Find Equation</u>

Substitute in variables [Circle Center Formula]: (x - -2)² + (y - 1)² = 5²
Simplify: (x + 2)² + (y - 1)² = 25

Topic: Pre-Calculus

Unit: Conics

Book: Pre-Calculus (McGraw Hill)

Answer:

$\displaystyle log_\frac{1}{2}(64)=-6$

Step-by-step explanation:

<u>Properties of Logarithms</u>

We'll recall below the basic properties of logarithms:

$log_b(1) = 0$

Logarithm of the base:

$log_b(b) = 1$

Product rule:

$log_b(xy) = log_b(x) + log_b(y)$

Division rule:

$\displaystyle log_b(\frac{x}{y}) = log_b(x) - log_b(y)$

Power rule:

$log_b(x^n) = n\cdot log_b(x)$

Change of base:

$\displaystyle log_b(x) = \frac{ log_a(x)}{log_a(b)}$

Simplifying logarithms often requires the application of one or more of the above properties.

Simplify

$\displaystyle log_\frac{1}{2}(64)$

Factoring $64=2^6$ .

$\displaystyle log_\frac{1}{2}(64)=\displaystyle log_\frac{1}{2}(2^6)$

Applying the power rule:

$\displaystyle log_\frac{1}{2}(64)=6\cdot log_\frac{1}{2}(2)$

Since

$\displaystyle 2=(1/2)^{-1}$

$\displaystyle log_\frac{1}{2}(64)=6\cdot log_\frac{1}{2}((1/2)^{-1})$

Applying the power rule:

$\displaystyle log_\frac{1}{2}(64)=-6\cdot log_\frac{1}{2}(\frac{1}{2})$

Applying the logarithm of the base:

$\mathbf{\displaystyle log_\frac{1}{2}(64)=-6}$
