Solve the equation. Check your solutions.<br> |4b+4|=|2b+8|
anzhelika [568]

Answer:

<h2><u>b = 2 or b = -2</u></h2>

Explanation:

|4b + 4| = |2b + 8|

<em>Solve absolute value</em>

|4b + 4| = |2b + 8|

Either 4b + 4 = 2b + 8 or 4b + 4 = −(2b + 8)

4b + 4 = 2b + 8 <em>(Possibility 1)</em>

4b + 4 − 2b = 2b + 8 − 2b <em>(Subtract 2b from both sides)</em>

2b + 4 = 8

2b + 4 − 4 = 8 − 4 <em>(Subtract 4 from both sides)</em>

2b = 4

2b / 2 = 4 / 2 <em>(Divide both sides by 2)</em>

b = 2

4b + 4 = −(2b + 8) <em>(Possibility 2)</em>

4b + 4 = −2b − 8 <em>(Simplify both sides of the equation)</em>

4b + 4 + 2b = −2b − 8 + 2b <em>(Add 2b to both sides)</em>

6b + 4 = −8

6b + 4 − 4 = −8 − 4 <em>(Subtract 4 from both sides)</em>

6b = −12

6b / 6 = -12 / 6 <em>(Divide both sides by 6)</em>

b = -2

A service station will be built on the highway, and a road will connect it with cray. How long will the new road be?
maxonik [38]

Answer:

46.2 mi is the right answer.

Step-by-step explanation:

In this question we will follow the property of congruence of two triangles.

Here two triangles formed are triangle formed by Alba, Cray and Blare and a triangle formed by Service station, Cray and Blare.

The distance between Alba and Blare = 130 mi

The distance between Alba and Cray = 120 mi

As we know in the congruent triangles all sides are in the same ratio.

Now we apply the property of the theorem

\frac{Distance(Alba-Cray)}{Distance(Alba-Blare)}= \frac{Distance(Cray-Service station)}{Distance(Cray-Blare)}

\frac{120}{130}=\frac{x}{50}

x=50\frac{120}{130}

x = 46.2 mi

Suppose that F(x) = x2 and G(X) = 2/3 x^2. Which statement best compares the graph of G(x) with the graph of F(x)?
masha68 [24]
<h2>Answer:The graph of G(x) is the graph of F(x) compressed vertically.</h2>

Step-by-step explanation:

Given that F(x)=x^{2} and G(x)=\frac{2}{3}x^{2}

F(x) is always positive because x^{2} is always positive.

G(x) is always positive because \frac{2}{3}x^{2} is always positive.

So,both are always positive.

So,there is no flipping over x-axis.

In F(x),the height of a point at x_{0} is x_{0}^{2}

In G(x),the height of a point at x_{0} is \frac{2}{3}x_{0}^{2}

So,height of any point has less height in G(x) than F(x)

So,the graph of G(x) is the graph of F(x) compressed vertically.

According to a height and weight chart, Bruce's ideal wrestling weight is 168 pounds. Bruce
jek_recluse [69]

Super simple

So he wants to be three pounds away from his ideal weight (168)

Which means he can either be 3 pounds under or 3 pounds over

So his min is 165, his max is 171
