The slope is 3 true or false?

Answers

Answer:

The slope IS NOT 3.

So the statement is FALSE.

Step-by-step explanation:

y = mx + b

If we change the graph shown into the format shown above it would be:

y = 1x - 3

mx = slope

Slope = 1x

b = y-intercept

b = -3

To find the slope you must do:

[tex]\frac{y}{x} =\frac{RISE}{RUN}[/tex]

y = rise

x = run

In the graph shown, the points are going up and shift to the right 1 unit.

So the slope is: 1x

Therefore, the statement, "The slope is 3" is actually false.

Answers

Answer:

1

Step-by-step explanation:

Characters are developed in the passage through their actions. Therefore, option A is correct.

What are the characters in a passage?

Characters are the people, animals, or entities portrayed in a literary work such as a passage, story, or novel. They are often the main focus of the narrative and drive the plot forward.

A character can be developed through various literary techniques such as actions. Their traits, motivations, and relationships with other characters help to create a deeper understanding of the story and its themes.

Well-developed characters often feel like real people, with complex personalities, histories, and emotions, which helps to engage the reader and create a sense of empathy or connection. Therefore, option A is correct.

Victoria filled up her car with gas before embarking on a road trip across the country. The car uses 1.75 gallons of gas for every hour driven, and after driving for 4 hours, there were 7 gallons of gas left in the tank. Write an equation for G,G, in terms of t,t, representing the number of gallons of gas remaining in Victoria's gas tank after tt hours of driving.

Answers

Answer:

G = 14 - 1.75(t)

Where G is the number of gallons of gas remaining;

14 represents the amount of gas in gallons in the full gas tank of the vehicle

t is the number of hours

Step-by-step explanation:

Here, we want to write an equation.

We are told that the car uses 1.75 gallons of gas every hour and after 4 hours 7 gallons were left

In the 4 hours, the amount of fuel used will be 1.75 * 4 = 7 gallons

So therefore since we have 7 gallons left, the amount of gallons in the full tank of the vehicle will be 7 + 7 = 14 gallons

Hence, the equation we want to write will be;

G = 14 - 1.75(t)

Use the substitution method to solve the system of equations. Choose the
correct ordered pair.
3x - y = 7

Answers

3x - y = 7
-> y = 3x - 7
2x - 2y = 2
Use the substitution method
2x - 2 ( 3x - 7 )=2
2x - 6x + 14 =2
-4x = 2-14
X = -12/-4
X = 3
Sub x = 3 into the eq y= 3x - 7
Y= 3*3-7
Y = 2 so the answer is D

5. Use the two given points and calculate the slope.
(3, 4), (5,9)

Answers

Answer:

[tex]\frac{5}{2}[/tex]

Step-by-step explanation:

For this situation we have the equation [tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex], where each variable represents a coordinate (e.g. in this case 4 could be [tex]y_{1}[/tex]). So first, let's define which coordinates will be the values of these variables:

(3,4): [tex]x_{1}, y_{1}[/tex]

(5,9): [tex]x_{2}, y_{2}[/tex]

Now we need to replace each variable with its given value: [tex]m = \frac{9-4}{5-3}[/tex]

And then do the subtraction to simplify: [tex]m=\frac{5}{2}[/tex]

Therefore, the slope of the line that passes through the points (3,4) and (5,9) is [tex]\frac{5}{2}[/tex].

The answer is 5/2. Cause of the slopes points so it would be 5/2.

Solve for x using the
distributive property.
9(5 - x) = 81
x = [?]

Answers

Answer:

[tex]\boxed {x = -4}[/tex]

Step-by-step explanation:

Solve for the value of [tex]x[/tex]:

[tex]9(5 - x) = 81[/tex]

-Use Distributive Property:

[tex]9(5 - x) = 81[/tex]

[tex]45 - 9x = 81[/tex]

-Subtract [tex]45[/tex] to both sides:

[tex]45 - 45 - 9x = 81 - 45[/tex]

[tex]-9x = 36[/tex]

-Divide both sides by:

[tex]\frac{-9x}{-9} = \frac{36}{-9}[/tex]

[tex]\boxed {x = -4}[/tex]

So, the value of [tex]x[/tex] is [tex]-4[/tex].

a rectangular tank is 76cm long, 50cm wide and 40cm high, how many litres of water can it hold?​

Answers

Answer:

Volume of a cuboid or rectangular tank = side × side × side

or

volume of a cuboid or rectangular tank = length× width × height

volume of the rectangular tank = 76 × 50 × 40

volume of the rectangular tank = 152000cm³

Therefore the rectangular tank can hold 152000cm³ litres of water

No. 5, Given BCM=ZYR, find each missing measure. Will mark brainliest!

Answers

Answer:

Step-by-step explanation:

Since, ΔBCM ≅ ΔZYR,

∠B ≅ ∠Z

∠C ≅ ∠Y

∠M ≅ ∠R

And BC ≅ ZY

CM ≅ YR

BM ≅ ZR

a). CM = YR = 11 m

b). BM = RZ = 15 m

c). YZ = BC = 8 m

d). m∠B = m∠Z = 45°

e). m∠M = 180° - [m(∠B) + m(∠C)]

              = 180° - (45 + 103)°

              = 180° - 148°

              = 32°

f). m∠Y = m∠C = 103°

Congruent triangles have equal corresponding sides and angles

The measure of the side lengths are:[tex]YZ =8[/tex], [tex]BM =15[/tex] and [tex]CM = 11[/tex]The measure of the angles are [tex]\angle B =45[/tex], [tex]\angle Y =103[/tex] and [tex]\angle M = 32[/tex]

The given parameter is:

[tex]\triangle BCM \cong \triangle ZYR[/tex]

This means that triangle BCM and ZYR are congruent.

So, we have the following congruent sides

[tex]YZ =CB[/tex]

[tex]BM =ZR[/tex]

[tex]CM =YR[/tex]

So, the measure of the side lengths are:

[tex]YZ =8[/tex]

[tex]BM =15[/tex]

[tex]CM = 11[/tex]

Also, we have the following congruent angles

[tex]\angle B = \angle Z[/tex]

[tex]\angle C = \angle Y[/tex]

[tex]\angle M = \angle R[/tex]

So, the measure of the angles are

[tex]\angle B =45[/tex]

[tex]\angle Y =103[/tex]

The measure of angle M is calculated using:

[tex]\angle M + \angle C + \angle B = 180[/tex]

So, we have:

[tex]\angle M + 103 + 45= 180[/tex]

[tex]\angle M + 148= 180[/tex]

Subtract 148 from both sides

[tex]\angle M = 32[/tex]

−6=3/8x−2+

1/8x

Step 1: Simplify both sides of the equation.

−6=3/8x−2+1/8x

−6=3/8x+−2+1/8x

−6=(3/8x+1/8x)+(−2)

(Combine Like Terms)

−6=1/2x+−2

−6=1/2x−2

Step 2: Flip the equation.

1/2x−2=−6

Step 3: Add 2 to both sides.

1/2x−2+2=−6+2

1/2x=−4

Step 4: Multiply both sides by 2.

2*(1/2x)=(2)*(−4)
