Answer 2

Answer:

12°

Step-by-step explanation:

Sum of interior angles of the triangle is 180°:

m∠A + m∠B + m∠C = 180°3x + 28° + 5x + 52° + 2x - 10° = 180°10x + 70° = 180°10x = 110°x = 11°

Find the measure of angle C:

m∠C = 2x - 10° = 2(11°) - 10° = 22° - 10° = 12°

Rewrite the following equation in slope-intercept form.
17x - 20y = -14

Answers

Answer:

17/20x + 7/10 = y

Step-by-step explanation:

You can solve this equation by moving values until they fit the form y=mx+b (slope-intercept form).

17x - 20y =  -1417x + 14 = 20y17/20x + 14/20 = y17/20x + 7/10 = y

Hope this helps!!

Answer:

Step-by-step explanation:

Slope intercept form y=mx+b

-20y = -14 -17x

Y = 14/20 + 17/20x

Y = 17/20x + 14/20

what happens to a compass when it is near a wire with insulation

Answers

Answer:

Every electric current produces magnetism. ... Since the compass needle is also a magnet, the magnetic field around the wire attracted and repelled the ends of the compass magnet and caused it to move.

Step-by-step explanation:

The temperature at 5:30 a.M. Was –4° Fahrenheit (F). Eight hours later, at 2:30 p.M., the temperature is the opposite of –4 °F. What is the temperature at 2:30?

Answers

Answer: 4°F

Step-by-step explanation:

From the question, we are informed that temperature at 5:30 a.m was –4°F and that eight hours later, at 2:30 p.m, the temperature is the opposite of –4°F.

The temperature at 2:30 will be 4°F since the opposite of -4 is +4. Also since there's an interval of 8 hours, it's likely that the temperature increased by 1° for every hour. In 8 hours, it'll have increased by 8°, therefore the temperature will then be:

= -4 + 8

= 4°F

X^3 - 100

Answers

Answer:

(x-10)(x²+10x+100)

Step-by-step explanation:

Given the expression

X^3 - 100

This ca also be expressed as;

X^3 - 100 = X³ - 10³

a³-b³ = (a-b)(a²+b²+ab)

Substitute a = x and b = 10

X³ - 10³ = (x-10)(x²+10²+10x)

X³ - 10³ = (x-10)(x²+10x+100)

Hence the factored form is (x-10)(x²+10x+100)

You have written equation for Main Street and Elm street. Since both equations are start with y=, how can you combine these two equations to write a new equation that involves only x?

Answers

Answer:

The two equations (representing value of variable Y) can be equated and converted into one single equation with X variable only

Step-by-step explanation:

If the starting of both the equation is from "Y=" then it means that whatever equation (having x variable) they are representing will be equal to each other as both the equation on one side are ultimately equal to Y

For example

Y = 3X + 5 ---- Eq (1)

Y = 7X +6  ---- Eq (2)

So both are equal

3X + 5 = 7X + 6

4X + 1 = 0

In this way the two equations (representing value of variable Y) can be equated and converted into one single equation with X variable only

An average person can type 2,4002,400 words per hour. Trista types at the same rate as the average person and made the double number line below to estimate how long it will take her to type her research paper. ​​Using Trista's double number line, estimate how long it will take her to type her 1,400-word research paper.

Answers

Answer:

35 minutes

Step-by-step explanation:

Given that:

Trista:

Average word type per hour = 2400 words /hr

For Trista to type her 1400 word research paper ;

It will take 'h' hour

If

2400 words = 1 hour

1400 words = h

Cross multiply :

2400h = 1400

h = 1400 / 2400

h = 0.5833333 hr

To minutes, it will take :

0.5833333 * 60 = 35 minutes

Hence, it will take Trista 35 minutes or 0.5833333 to type her 1400 words research paper.

Need an image

Step-by-step explanation:

Sketch the image of A (-3,5) after the described glide reflection.
Translation: (x, y)=(x - 2, y + 5)
Reflection: in y =4



Plz HELP me out I really don’t understand this!

Answers

Answer:

Translation (x, y) = (x - 2, y + 5)

(x, y) = (x - 2, y + 5)

(-3, 5) = (-3 - 2, 5 + 5)

(-3, 5) = (-5, 10)

So this means that point A' (-5, 10) is your translation of point A (-3, 5) .

Now let us look at the reflection. It says to reflect across the y = 4. Basically you will draw a horizontal straight line on 4. Count how many units is point A (-3, 5) is. Then do it on the other side of the line. Point A' (-3, 3) is reflected across y = 4 of point A (-3, 5).

Hope this helps, thank you !!

If -6x+12=0 and 4y + 5=9, what is the value of ×+y​

Answers

Answer:

-9p²+6p+2/4p²

Step-by-step explanation:

Given the expression

(p ^ 2 + 6p + 2)/(4p ^ 2) - (10p ^ 2)/(4p ^ 2)

Find the LCM

The LCM = 4p²

[p²+6p+2 - (10p²)]/4p²

Expand

p²-10p²+6p+2/4p²

-9p²+6p+2/4p²

hence the required expression is -9p²+6p+2/4p²
