Answer  :C

Step-by-step explanation:  For any given function, all first input values (x-values/coordinates) in the relation are considered as the domain values. While the output values (y-values/coordinates) make up the range of the given function.

The mapped relation that has a domain of {1,2,3}, is the mapped relation that has 1, 2, and 3 on the input side on our left.

Therefore, the mapped relation in option C is the answer.

Answer:

the answer is letter A.

Step-by-step explanation:

m=y²-y¹/x²-x¹

m=(-6)-16/(-19)-15

m=-22/-34

m=11/17

I'm guessing you mean to say that sum of 5 consecutive odd numbers is 135. In that case, let x be the first number. Then

x + (x + 2) + (x + 4) + (x + 6) + (x + 8) = 135

5x + 20 = 135

5x = 115

x = 23

So the numbers are 23, 25, 27, 29, and 31.

If you really did mean 555 consecutive odd numbers summing to 135,135,135, the process is the same, but you would find a non-integer solution so that wouldn't be possible.

Answer:

68 sandwiches

Step-by-step explanation:

Given that,

A shop sells 15 sandwiches in 10 minutes.

10 minutes = (10/60) hour = (1/6) hour

In (1/6) hour shop sells 15 sandwiches

In 1 hour = 90 sandwiches

To find, no of sandwiches in 3/4 hours, multiply 3/4 by 90. So,

In 3/4 hour = [tex]90\times \dfrac{3}{4}=67.5[/tex] sandwiches

or

≅ 68 sandwiches

So, 68 sandwiches can be made in 3/4 hour.

Given:

Base pay = $100 per day

Commission = 1% of the dollar amount of all sales that she makes

To find:

The equation representing Harper's total pay on a day.

Solution:

Let P be the Harper's total pay on a day if she sells x dollars worth of computers.

Commission on x dollars sales = 1% of x = 0.01x

Total pay = Base pay + Commission

[tex]P=100+0.01x[/tex]

Therefore, the required equation is [tex]P=100+0.01x[/tex].

Answer:-0.75x+8.1

Step-by-step explanation:

Use a coordinate proof to prove that mid segment mn of triangle pqr is parallel to pr and half the length of pr. which is the first best step? a. place the triangle on a coordinate grid such that vertex p is at the origin, and pr lies on x-axis. b. place the triangle on a coordinate grid such that vertex p is on y-axis and vertex r us on the x-axis

Please consider marking brainliest! :)

Place the triangle on a coordinate grid such that QR lies on the x-axis and PQ lies in the y-axis. Therefore, option D is the correct answer.

If we start with Step A, we are unknown about points Q and R and these two points need to be located somewhere.

If we start with step B, we are unknown about point Q and it needs to be located.

If we start with step C, we are unknown about points P and R, and these two points need to be located.

Let us start with step D,

It is given that,

In triangle PQR, QR lies on the x-axis while PQ lies on the y-axis means Q will be at the origin

Coordinates of Q will be (0, 0)

Let us take coordinates of R (4, 0) and P as (0, 4)

Let us take the midpoints of PQ &PR as ‘S’ & ‘T’ respectively.

Now, coordinates of S and T can be found using the Mid-Point formula

Coordinates of mid-point = (x₁+x₂)/2, (y₁+y₂)/2

Coordinates of S= (2, 0)

Coordinates of T= (2, 2)

Here,

We have to prove ST= QR/2 and ST Parallel to QR.

(1) Now, using distance formula,

ST = √([(0-2)²+(2-2)²])

ST = 2 (1/2 ×QR)

(2) Now, in order to prove ST is parallel to QR, we need to prove that the slope of ST is equal to the slope of QR.

Using slope formulae

Slope of ST = (2-2)/(2-0) = 0

Slope of QR = 0, as we know slope of x-axis is 0.

So, the value of ST is half of QR as well as it is parallel to QR.

Therefore, step D is the best option to start with.

Answer:

[tex]x=\frac{30}{7}[/tex]

Step-by-step explanation:

Step 1: Subtract 10 from both sides.

−7x=−30

Step 2: Divide both sides by -7.

−7x /−7  =  −30 /−7

x= 30 /7

Step-by-step explanation:

-4 +5 is 1 not -1 lol

The incorrect step where Kelcy did mistake is given by: Option A: She added ⟨–4, 3⟩ and ⟨5, 1⟩ incorrectly.

Suppose that two vectors are given as:

[tex]x = \: < a,b > \\y= \: < c,d >[/tex]

Then, their addition is given as:

[tex]x + y = \: < a +c , b + d >[/tex]

For this case, we can see that when Kelcy added <-4,3 > and <5,1>, she didn't add -4 and 5 correctly, as it results in +1, and not -1,

Thus, <-4,3> + <5,1> = <1,4>

Thus, wrong addition caused error in the solution.

Thus, the incorrect step where Kelcy did mistake is given by: Option A: She added ⟨–4, 3⟩ and ⟨5, 1⟩ incorrectly.

17.5

Step-by-step explanation:

175% is written as 175/100. If you move the decimal at the end over twice you get 1.75/1 which is just 1.75. You then multiple 10 by 1.75 and you get 17.5

Answer:

6.75

Step-by-step explanation:

A of rectangle = 2*1.5=3

A or triangle= (7-2)*1.5/2 = 5*1.5/2 =3.75

Area trapezoid =A rectangle +Atriangle = 3+3.75=6.75

Answer:

C : 6.75 yd.

Step-by-step explanation:

first, you divide the trapezoid into two shapes, a square, and a triangle. For the square's area, you multiply 2yd and 1,5 yd to get 3 yd. Then for the triangle's area, since the bottom side of the trapezoid is a side for both the triangle and the square, the square already took 2yd if that makes sense. You multiply 5yd and 1.5 yd to get 7.5 yd. Since its a triangle, you divide the area of the triangle by 2, which is 3.75 yd. To get the total area of the trapezoid, you then add 3yd plus 3.75 yd to get 6.75 yd. ²

Let's solve your equation step-by-step.

43x−4=5−x

Step 1: Simplify both sides of the equation.

43x−4=5−x

43x+−4=5+−x

43x−4=−x+5

Step 2: Add x to both sides.

43x−4+x=−x+5+x

73x−4=5

Step 3: Add 4 to both sides.

73x−4+4=5+4

73x=9

Step 4: Multiply both sides by 3/7.

(37)*(73x)=(37)*(9)

The product [tex](2x + 3)(x + k)[/tex] is [tex]2x^2+13x+15[/tex].

To find:

The value of k.

Solution:

According to the question,

[tex](2x + 3)(x + k)=2x^2+13x+15[/tex]

Using distributive property, we get

[tex]2x^2+2xk+3x+3k=2x^2+13x+15[/tex]

[tex]2x^2+(2k+3)x+3k=2x^2+13x+15[/tex]

On comparing both sides, we get

[tex]3k=15\text{ and }2k+3=13[/tex]

[tex]k=\dfrac{15}{3}\text{ and }2k=13-3[/tex]

[tex]k=5\text{ and }2k=10[/tex]

[tex]k=5\text{ and }k=5[/tex]

Both value of k are same, i.e., 5.

Therefore, the value of k is 5.
