Step-by-step explanation:

(0,4) shows the y-intercept of +4

Use slope formula to find slope:

7-4/2-1 = 3/1 = 3

M (slope)= 3x

Answer:

y=3x+1

Since we know that the line is increasing by 3 and since when x is equal to zero, and y is equal to 1 we know that we will need to add 1.

So Y=3x+1

Answers

Answer:

x=30

Step-by-step explanation:

You have to isolate for x. This means you need to somehow get x on one side of the equation all alone. In this case it is x-9=21 which means some unknown number x with 9 subtracted from it is equal to 21. When we bring the -9 over to the other side to get the x all alone, we have to switch the sign of the -9 so it becomes +9. This means x=21+9, and if you add that you'll get 30!

Answer:

7.5

Step-by-step explanation:

The square has 4 equal sides, so you take the p,(30) and divide it. 30/4 = 7.5

To check your answer add 7.5 four times since the square has 4 equal sides.

7.5 + 7.5 = 15

15 + 7.5 = 22.5

22.5 + 7.5 = 30

11x - 16 = -49

x = _____

Answers

Answer:

x = -3

Step-by-step explanation:

Given,

11x - 16 = -49

=> 11x = - 49 + 16

=> 11x = -33

[tex] = > x = \frac{ - 33}{11} [/tex]

=> x = -3 (Ans)

Answer:

x=-3

Step-by-step explanation:

1. Add 16 to both sides of the equation

11−16=−49

11−16+16=−49+16

2. Simplify.

IF you add the numbers you will get:

11x=-33

3. Divide both sides of the equation by the same term

11=−33

11/11=−33/11

4. Simplify.

x=-3

Which choice shows the corresponding sides as equal ratios?

Answers

The first one

Because you are dividing the second triangle by the first one

Option A,  DE/AB=EF/BC=DF/AC shows the  corresponding sides as equal ratios

What is Triangle?

A triangle is a three-sided polygon that consists of three edges and three vertices.

Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion .

From the given triangles

In triangle ABC, the lengths AB is 3, BC is 4 and CA is 5.

In triangle DEF, the lengths DE is 6, EF is 8 and DF is 10.

As the two triangles are similar.

DE/AB=6/3=2

EF/BC=8/4=2

DF/AC=10/5=2

So DE/AB=EF/BC=DF/AC=2

Hence, Option A DE/AB=EF/BC=DF/AC shows the  corresponding sides as equal ratios

Answers

Answer:

Red, orange, yellow, green, cyan, blue and purple.

Step-by-step explanation:

The rainbow is a colorful visual and meteorological phenomenon, in which the range of colors that compose the visible light in the sky appears. The phenomenon occurs when the sun's rays fall on raindrops in the Earth's atmosphere and is an example of refraction, after reflection. Each color is refracted at a different angle inside the droplets (which act like small prisms), it undergoes a different deflection and so the visible white light is analyzed in the different colors that compose it.

Point D is in the interior of ∠ABC. What is m∠DBC?

Answers

37.5 degrees

we know angled like this always have 180 degrees total between the 2. which means we can set up a little equation to solve for x. The equation is (3x+22)+(x-4)= 180. Initially we can take the solid numbers (22 and -4) and get rid of them by taking them to the 180. 180- 22 is 158. 158 + 4 is 162. now we have 3x + x = 162. we combine like terms. means we end up with 4x =162. We now divide by 4 which means we get 40.5. Now we know x is 40.5. Now dbc is just 40.5- 4 which is 37.5.

The measure of angle ∠DBC is,

⇒ ∠DBC = 35.5°

What is mean by Angle?

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.

Given that;

Point D is in the interior of ∠ABC.

And, ∠ABD = (3x + 22)°

⇒ ∠DBC = (x - 4)°

Clearly, Both angle make a linear pair.

Hence, We get;

⇒ ∠ ABD + ∠DBC = 180°

⇒ (3x + 22) + (x - 4) = 180°

⇒ 3x + 22 + x - 4 = 180

⇒ 4x + 18 = 180

⇒ 4x = 180 - 18

⇒ 4x = 162

⇒ x = 162/4

⇒ x = 40.5

Hence, The measure of angle ∠DBC is,

⇒ ∠DBC = (x - 4)°

⇒ ∠DBC = (40.5 - 4)°

⇒ ∠DBC = 35.5°
