Is the relation a function?

Answer:

C

Step-by-step explanation:

24 + 2 = 26 ---> x = 26, y = 11

Answer:

the answer is c.) x = 26, y = 11

Answer: 1/27 is greater than 1 7/20 I believe.

Answer:

c because 5×4=20 and 3×5÷2=7.5= 27.5

y= -1 x + 4

found the slope and then rearranged y=mx+b to find b

lmk if you need any other help :)

Answer:

x=2

Step-by-step explanation:

Answer:

x = 1

Step-by-step explanation:

Plan A: 20 + 10x

Where, x = fee per lesson

Plan B: $3 × 10 lessons = $30

Equate plan A and plan B

Plan A = Plan B

20 + 10x = 30

10x = 30 - 20

10x = 10

x = 10/10

= 1

x = 1

Answer:

104

Step-by-step explanation:

156 divided by 6. 156-26=130. now 20 percent of 130 =26. 130-26 = 104

Answer:

C  [tex]\frac{48}{70}[/tex]

Step-by-step explanation:

Option C - [tex]\frac{48}{70}[/tex] is incorrect because when multiplying the numerator and denominator of the fraction [tex]\frac{7}{10}[/tex] by 7, you’re suppose to get [tex]\frac{49}{70}[/tex].

Answer:

$187.5

Step-by-step explanation:

25% of $750 = $187.5!

All I had to do was divide 750 by 4 and got my answer. You can also double check by multiplying 187.5 by 4 and you'll get the same answer.

Answer:

1)b

2)d)80/360×36π≈25.12cm²

4)d)32.5

5)c)135°

6)d)4π/3

Step-by-step explanation:

1) because as we know

Circle equation

=(x-a)²+(y-b)²=r²

=(x-5)²+(y+1)²=36 (given)

=(x-(+5))²+(y-(-1))²=6²

So

C(5,-1)and r=6

2)as we know area of sector

=Theta/360×πr²

=80/360×6²π

80/360×36×3.14

80/10×3.14

=25.12

4)to figure out 4 we have to separate the shape into 2 parts

First  semi-circul

Second rectangle

So the parameter of the shape

=Circumference of semi-circul + the parameter of the rectangle

=[10π×½+2(10+3.4)]-10 (as the dashed line is not a part of parameter)

=[15.7+26.8]-10

=32.5

5)3π/4

3×180/4

540/4

135

6)240°

240°×π/180°

4π/3

Answer:

linear

Step-by-step explanation:

If it is linear, for each unit increase in x, there should be a constant change in y.

x=1, y=5

in x=2, we expect y to increase by 5 units, so 5+5 = 10, which is right.

x=3, expect 5 units increase, and we do see that as 10+5 = 15.

x=4, expect 5 unit increase, and 15+5 =20 so we see that

this is linear function, if nonlinear then we would see different changes of y for each unit increase of x.

Answer:

D.Lindsay makes 480 candles. She divides 480 by 15 to get 32. She does not make enough candles.

Step-by-step explanation:

The explanation of the sufficient candles that are required to check whether she reach her goal or not is as follows:

She makes 480 candles that come from

= 24 candles each days × 20 days

= 480 candles

Now if we divide the 480 candles from 15 so we get 32

This is less than the minimum candles required i.e. 35

So, the option D is correct

Answer:

b // f

c // e

Step-by-step explanation:

b // f

89.5 = 180 - 90.5

89.5 = 89.5       {corresponding angles are congruent.So b // f}

c//e

91.5 = 180 - 88.5

91.5 = 91.5    {corresponding angles are congruent.So b // f}

Answer:

What is (2+0.4+0.6)

First we have to arrange the numbers in sequence...

[tex]2.0 \: + \: 0.4 \: + 0.6 \\ 3.0 \: or \: 3[/tex]

Here I have taken this 0 after the point ..as the rest of the digit are in tenths place or after the point...

The answer is 3.

We will not calculate the 0 as it does not have any value.

Ans) 3

Step-by-step explanation:

Step-by-step explanation:

Let x is the number of type 1 cabinets produced and y is the number of type 2 cabinets produced.

The total no of cabinets are 100

Equation will be : x+y = 110

We can write it as : y = 110-x ...(1)

Last week, the number of type 2 cabinets produced exceeded twice the number of type 1 cabinets produced by 20.

Equation will be : y = 2x + 20 ...(2)

Put the value of y from equation (1) into equation (2).

110-x = 2x + 20

Combining like terms,

110-20 = 2x+x

90 = 3x

x = 30

Put the value of x in equation (1) :

y = 110-30

y = 80

Hence, there are 30 cabinets of type 1 and 80 cabinets of type 2.

a = [tex]\frac{b-bc}{d}[/tex]

Step-by-step explanation:

Given

bc + ad = b ( subtract bc from both sides )

ad = b - bc ( isolate a by dividing both sides by d )

a = [tex]\frac{b-bc}{d}[/tex]
