Answer:

The slope of the line is 1.

Step-by-step explanation:

To solve this problem, we should use the equation for slope, which is given below:

slope = m = (y2-y1)/(x2-x1)

We can now plug in two points that are given in the table.

slope = m = (9-5)/(9-5)

We can simplify our expression for slope by first computing the subtraction inside the parentheses.

slope = m = 4/4

If we simplify the expression further by dividing the numerator by the denominator, we get:

slope = m = 1

Therefore, the correct answer is slope = 1.

Hope this helps!

Find measure of angle 1

Just look at the top triangles
Angles in a triangle add up to 180°

To find the angle next to 36°:
It shows that all together its a 90° angle so you do 90-36= 54°

To find the angle next to 88°:
Angles on a straight line add up to 180° so you do 180-88= 92°

You now have the 2 of the angles in the triangle with angle 1

You now add these 2 angles so 54+92= 146°
and as angles in a triangle add up to 180° you do 180-146= 34°

So angle 1 is 34°

Not sure if i got this right?

Answer:

The effect it will have on the volume is;

The volume will be 8 times larger

Step-by-step explanation:

The dimensions of the given prism are;

The length of the prism, l = 5 in.

The breadth of the prism, b = 5 in.

The slant height of the prism,  = 4 in. by 5 in.

The height of the prism, h = 7 in.

The shape of the prism = Parallelepiped

The volume of a parallelepiped = Area of Base × Height of the prism

The base area of the parallelepiped = The length × Breadth of the parallelepiped

∴ The base area of the given parallelepiped = 5 in. × 5 in. = 25 in.²

The volume of the given parallelepiped, V₁ is found as follows;

V₁ = 5 in. × 5 in. × 7 in. = 25 in.² × 7 in. = 175 in.³

When a scale factor of 2 in applied to the dimensions of the prism, we have;

The new volume, V₂ =  2 × 5 in. × 2 × 5 in. × 2 × 7 in.

∴ V₂ = 2 × 2 × 2 × 5 in. × 5 in. × 7 in. = 8 × 5 in. × 5 in. × 7 in. = 8 × V₁

Therefore;

V₂ = 8 × V₁

The volume of the image of the object, V₂ after applying a scale factor of 2 is 8 times larger than the volume of the object, V₁.

Julli [10]

(a). The solutions are 0 and ⁸/₃.

(b). The solutions are 1 and ¹³/₃.

(c). The equation has no solution.

(d). The only solution is ²¹/₂₀.

(e). The equation has no solution.

<h3>Further explanation</h3>

These are the problems with the absolute value of a function.

For all real numbers x,

\boxed{ \ |f(x)|=\left \{ {{f(x), for \ f(x) \geq 0} \atop {-f(x), for \ f(x) < 0}} \right. \ }

<u>Problem (a)</u>

|4 – 3x| = |-4|

|4 – 3x| = 4

<u>Case 1</u>

\boxed{ \ 4 - 3x \geq 0 \ } \rightarrow \boxed{ \ 4\geq 3x \ } \rightarrow \boxed{ \ x\leq \frac{4}{3} \ }

For 4 – 3x = 4

Subtract both sides by four.

-3x = 0

Divide both sides by -3.

x = 0

Since \boxed{ \ 0\leq \frac{4}{3} \ }, x = 0 is a solution.

<u>Case 2</u>

\boxed{ \ 4 - 3x < 0 \ } \rightarrow \boxed{ \ 4 < 3x \ } \rightarrow \boxed{ \ x > \frac{4}{3} \ }

For -(4 – 3x) = 4

-4 + 3x = 4

Add both sides by four.

3x = 8

Divide both sides by three.

x = \frac{8}{3}

Since \boxed{ \ \frac{8}{3} > \frac{4}{3} \ }, \boxed{ \ x = \frac{8}{3} \ } is a solution.

Hence, the solutions are \boxed{ \ 0 \ and \ \frac{8}{3} \ }  

————————

<u>Problem (b)</u>

2|3x - 8| = 10

Divide both sides by two.

|3x - 8| = 5  

<u>Case 1</u>

\boxed{ \ 3x - 8 \geq 0 \ } \rightarrow \boxed{ \ 3x\geq 8 \ } \rightarrow \boxed{ \ x\geq \frac{8}{3} \ }

For 3x - 8 = 5

Add both sides by eight.

3x = 13

Divide both sides by three.

x = \frac{13}{3}

Since \boxed{ \ \frac{13}{3} \geq \frac{4}{3} \ }, \boxed{ \ x = \frac{13}{3} \ } is a solution.

<u>Case 2</u>

\boxed{ \ 3x - 8 < 0 \ } \rightarrow \boxed{ \ 3x < 8 \ } \rightarrow \boxed{ \ x < \frac{8}{3} \ }

For -(3x – 8) = 5

-3x + 8 = 5

Subtract both sides by eight.

-3x = -3

Divide both sides by -3.

x = 1  

Since \boxed{ \ 1 < \frac{8}{3} \ }, \boxed{ \ x = 1 \ } is a solution.

Hence, the solutions are \boxed{ \ 1 \ and \ \frac{13}{3} \ }  

————————

<u>Problem (c)</u>

2x + |3x - 8| = -4

Subtracting both sides by 2x.

|3x - 8| = -2x – 4

<u>Case 1</u>

\boxed{ \ 3x - 8 \geq 0 \ } \rightarrow \boxed{ \ 3x\geq 8 \ } \rightarrow \boxed{ \ x\geq \frac{8}{3} \ }

For 3x – 8 = -2x – 4

3x + 2x = 8 – 4

5x = 4

x = \frac{4}{5}

Since \boxed{ \ \frac{4}{5} \ngeq \frac{8}{3} \ }, \boxed{ \ x = \frac{4}{5} \ } is not a solution.

<u>Case 2</u>

\boxed{ \ 3x - 8 < 0 \ } \rightarrow \boxed{ \ 3x < 8 \ } \rightarrow \boxed{ \ x < \frac{8}{3} \ }

For -(3x - 8) = -2x – 4

-3x + 8 = -2x – 4

2x – 3x = -8 – 4

-x = -12

x = 12

Since \boxed{ \ 12 \nless \frac{8}{3} \ }, \boxed{ \ x = 12 \ } is not a solution.

Hence, the equation has no solution.

————————

<u>Problem (d)</u>

5|2x - 3| = 2|3 - 5x|  

Let’s take the square of both sides. Then,

[5(2x - 3)]² = [2(3 - 5x)]²

(10x – 15)² = (6 – 10x)²

(10x - 15)² - (6 - 10x)² = 0

According to this formula \boxed{ \ a^2 - b^2 = (a + b)(a - b) \ }

[(10x - 15) + (6 - 10x)][(10x - 15) - (6 - 10x)]] = 0

(-9)(20x - 21) = 0

Dividing both sides by -9.

20x - 21 = 0

20x = 21

x = \frac{21}{20}

The only solution is \boxed{ \ \frac{21}{20} \ }

————————

<u>Problem (e)</u>

2x + |8 - 3x| = |x - 4|

We need to separate into four cases since we don’t know whether 8 – 3x and x – 4 are positive or negative.  We cannot square both sides because there is a function of 2x.

<u>Case 1</u>

  • 8 – 3x is positive  (or 8 - 3x > 0)
  • x – 4 is positive  (or x - 4 > 0)

2x + 8 – 3x = x – 4

8 – x = x – 4

-2x = -12

x = 6

Substitute x = 6 into 8 – 3x ⇒ 8 – 3(6) < 0, it doesn’t work, even though when we substitute x = 6 into x - 4 it does work.

<u>Case 2</u>

  • 8 – 3x is positive  (or 8 - 3x > 0)
  • x – 4 is negative  (or x - 4 < 0)

2x + 8 – 3x = -(x – 4)

8 – x = -x + 4

x – x =  = 4 - 8

It cannot be determined.

<u>Case 3</u>

  • 8 – 3x is negative (or 8  - 3x < 0)
  • x – 4 is positive. (or x - 4 > 0)

2x + (-(8 – 3x)) = x – 4

2x – 8 + 3x = x - 4

5x – x = 8 – 4

4x = 4

x = 1

Substitute x = 1 into 8 - 3x, \boxed{ \ 8 - 3(1) \nless 0 \ }, it doesn’t work. Likewise, when we substitute x = 1 into x – 4, \boxed{ \ 1 - 4 \not> 0 \ }

<u>Case 4</u>

  • 8 – 3x is negative (or 8 - 3x < 0)
  • x – 4 is negative (or x - 4 < 0)

2x + (-(8 – 3x)) = -(x – 4)

2x – 8 + 3x = -x + 4

5x + x = 8 – 4

6x = 4

\boxed{ \ x=\frac{4}{6} \rightarrow x = \frac{2}{3} \ }

Substitute x = \frac{2}{3} \ into \ 8-3x, \boxed{ \ 8 - 3 \bigg(\frac{2}{3}\bigg) \not< 0 \ }, it doesn’t work. Even though when we substitute x = \frac{2}{3} \ into \ x-4, \boxed{ \ \bigg(\frac{2}{3}\bigg) - 4 < 0 \ } it does work.

Hence, the equation has no solution.
