Answer:

Option 2 is correct that is NO ; The triangles are not similar.

Step-by-step explanation:

Given: Measurements of the sides of triangle.

Say sides of triangle 1 = 3 , 5 , 6

Sides of triangle 2 = 4 , 6 , 8

We have to find if triangles are similar or not and if they are similar then to find their ratio.

Since, We are given with only sides of the triangle.

Then if they are similar then they will be by Side-Side-Side similarity criteria.

Here, Two triangles are said to be similar by Side-Side-Side Criteria if ratio of their sides are equal.

But clearly from given values , all ratios are not equal.

\frac{3}{4}=\frac{6}{8}\neq\frac{5}{6}

Or

\frac{3}{6}\neq\frac{5}{8}\neq\frac{6}{4}

No possible pair give equal ratio.

Therefore, Option 2 is correct that is NO ; The triangles are not similar.

Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = 4x + 3

f(-5) is x = -5

<u>Step 2: Evaluate</u>

  1. Substitute in <em>x</em>:                    f(-5) = 4(-5) + 3
  2. Multiply:                               f(-5) = -20 + 3
  3. Add:                                     f(-5) = -17

Write the slope-intercept form of the equation of the line through the given points.
Yuri [45]
<h3>Answer:  y = 3x+4</h3>

Slope = 3

y intercept = 4

========================================================

Explanation:

Let's find the slope.

m = \text{slope}\\\\m=\frac{\text{rise}}{\text{run}}\\\\m = \frac{\text{change in y}}{\text{change in x}}\\\\m = \frac{y_2-y_1}{x_2-x_1}\\\\m = \frac{7-4}{1-0}\\\\m = \frac{3}{1}\\\\m = 3

The slope is m = 3.

The y intercept is b = 4 due to the point (0,4). The y intercept <u>always</u> occurs when x = 0.

We'll then plug those m and b values into y = mx+b to get the answer y = 3x+4

-----------

As a way to check the answer, plugging x = 0 should lead to y = 4

y = 3x+4

y = 3*0+4

y = 0+4

y = 4

So that works out. Let's try x = 1. It should produce y = 7

y = 3x+4

y = 3*1+4

y = 3+4

y = 7

That works out also. The answer is fully confirmed.

PLEASE HELP!!!!! 13. PTS+ PLEASE SUPER EASY
Brums [2.3K]

Answer:

1. A. Set the angle and arc measures equal.

2. B. major arc

3. B. Multiply the angle measure by 2.

4. A. minor arc

Step-by-step explanation:

1. If the intercepted arc is made from a central angle then angle of arc is equal to the central angle

2. 190 is a bigger angle than 170(angle of the remaining arc)

   Therefore it is a major arc.

3.If the intercepted arc is made from a inscribed angle, then the angle of arc is double of the inscribed angle.

4. 115 < 245

   Therefore it is a minor arc.

2x-4/5=4<br> plsss answer quick
nikdorinn [45]

Answer:

<h2>x = 12</h2>

Step-by-step explanation:

\frac{2x - 4}{5}  =4

First of all multiply through by 5 to eliminate the fraction

That's

5 \times  \frac{2x - 4}{5}  = 4 \times 5 \\ 2x - 4 = 20

Next using the addition property add 4 to both sides of the equation

We have

2x - 4 + 4 = 20 + 4 \\ 2x = 24

<u>Divide both sides by 2</u>

\frac{2x}{2}  =  \frac{24}{2}

We have the final answer as

<h3>x = 12</h3>

Hope this helps you
