Answer:

Look at the attachment below :)

Step-by-step explanation:

When we are given just a X or a Y coordinate, we just graph that. In this example, y will always be -3 and x will be anything so its a straight line.

Answer:

x = - 1 and x = - 7

Step-by-step explanation:

Given

x² + 8x + 7 = 0 ← in standard form

(x + 1)(x + 7) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 1 = 0 ⇒ x = - 1

x + 7 = 0 ⇒ x = - 7

Answer:

Weight of each large box [tex]x=15.75kg[/tex]

Weight of each small box [tex]y=13.75kg[/tex]

Step-by-step explanation:

Given:- Two equations are given,

Equation 1 :- [tex]7x+9y=234[/tex]

Equation 2:- [tex]5x+3y=120[/tex]

let,

x=weight of large box in Kilogram.

y=weight of small box in Kilogram.

Now,

multiply Equation 1 by 2 and Equation 2 by 6,

So we get 2 new equations,

Equation 3:- [tex]14x+18y=468[/tex]

Equation 4:- [tex]30x+18y=720[/tex]

Now after subtracting Equation 3 from Equation 4 we will get a new equation,

i.e. Equation 5:- [tex]16x=252[/tex]

therefore [tex]x=15.75[/tex]

now, put the value of x in Equation 1, so we will get

[tex](7x15.75)+9y=234[/tex]

[tex]110.75+9y=234[/tex]

[tex]9y=234-110.75[/tex]

[tex]9y=123.75[/tex]

[tex]y=123.75/9[/tex]

[tex]y=13.75[/tex]

So, weight of each large box i.e. [tex]x=15.75 kilogram[/tex]

and weight of each small box i.e. [tex]y=13.75 kilogram[/tex]

The solution set graphic is C - Points on negative x-axis.

Explanation:

The correct solution set graphic for this question is C - Points on negative x-axis.

To determine the solution set graphically, you would need to plot all the possible values of the equation or inequality on a coordinate plane. Option A - Infinite set of points on the line would represent a linear equation or inequality with multiple solutions. Option B - Empty set would mean that there are no solutions to the equation or inequality. Option C - Points on negative x-axis would indicate that the equation or inequality has solutions only on the negative x-axis.

Answer:

He have 32 quarters and 15 dimes.

Step-by-step explanation:

Given:

Asa saves dimes and quarters so that he will have exact change for the bus.

He has 47 coins that are worth $9.50.

Now, to find the number of coin each he have.

Let the number of quarters be [tex]x.[/tex]

And the number of dimes be [tex]y.[/tex]

So, the total number of coins are:

[tex]x+y=47.[/tex]

[tex]y=47-x.[/tex].........(1)

As given the total worth of coins = $9.50

And the value of a quarter = $0.25 and the value of a dime = $0.10.

Now, the total worth of coins are:

[tex]0.25x+0.10y=9.50[/tex]

Putting the equation (1) in the place of [tex]y[/tex] we get:

[tex]0.25x+0.10(47-x)=9.50[/tex]

[tex]0.25x+4.7-0.10x=9.50[/tex]

[tex]0.15x+4.7=9.50[/tex]

Subtracting both sides by 4.7 we get:

[tex]0.15x=4.80[/tex]

Dividing both sides by 0.15 we get:

[tex]x=32.[/tex]

The number of quarters = 32.

Now, putting the value of [tex]x[/tex] in equation (1) we get:

[tex]y=47-32.[/tex]

[tex]y=15.[/tex]

The number of dimes = 15.

Therefore, he have 32 quarters and 15 dimes.

30 = 2 × 3 × 5

45 = 3 × 3 × 5

The prime factor '5' is common in the factorisation of 10, 30 and 45

So, the greatest common factor of 10, 30 and 45 is 5.

Answer:

Second table

Step-by-step explanation:

Proportional relationships between x and y satisfied the following equation y = k*x, where k is some constant. Rearranging we get: k = y/x. So, if we take every pair y-x and divided them, we have to find the same k.

- Division y/x for the first table:

2/1 = 2

5/3

8/4 = 2

14/7 = 2       It is not a proportional relationship

- Division y/x for the second table:

1/7

2/14 = 1/7

4/28 = 1/7

5/35 = 1/7       It is a proportional relationship

- Division y/x for the third table:

4/1 = 4

10/2 = 5

12/3 = 4

16/4 = 4        It is not a proportional relationship

- Division y/x for the fourth table:

5/2.5 = 2

6/3 = 2

10/5 = 2

15/6 = 5/2        It is not a proportional relationship

Answer:

Measurement of JL=8

Step-by-step explanation:

Given:-

[tex]\triangle JKL\ is\ right\ angle\ triangle[/tex]

[tex]m\angle J=62\ degree[/tex]

JK=17

[tex]sin\ 62\ degree= 0.88[/tex]

[tex]cos\ 62\ degree= 0.47[/tex]

[tex]tan\ 62\ degree= 1.88[/tex]

To find measurement of JL=?

Now,

[tex]cos\theta=\frac{adjacent\ side}{hypotenuse}[/tex]

[tex]cos\ 62\ degree=\frac{JL}{17}[/tex]

[tex]0.47=\frac{JL}{17}[/tex]

[tex]JL=0.47\times 17[/tex]

[tex]JL=7.99[/tex]

[tex]JL=8[/tex]

Therefore measurement of JL=8

Answer:

x = 11, y = 3

Step-by-step explanation:

9x + 25 and 13x - 19 are corresponding angles and congruent, thus

13x - 19 = 9x + 25 ( subtract 9x from both sides )

4x - 19 = 25 ( add 19 to both sides )

4x = 44 ( divide both sides by 4 )

x = 11

Thus

13x - 19 = (13 × 11) - 19 = 143 - 19 = 124°

13x- 19 and 17y + 5 form a straight angle and are supplementary, thus

13x - 19 + 17y + 5 = 180, that is

124 + 17y + 5 = 180

129 + 17y = 180 ( subtract 129 from both sides )

17y = 51 ( divide both sides by 17 )

y = 3

Answer:

x=6

Step-by-step explanation:

16x-8+2x=100

18x-8=100

18x=100+8

18x=108

x=108/18

x=6

14x=108 is the equivalent equation of the equation 16x – 8 + 2x = 100.

Two or more expressions with an Equal sign is called as Equation.

The given equation is 16x – 8 + 2x = 100.

Sixteen times of x minus eight plus two times of x equal to hundred.

16x – 8 + 2x = 100.

We need to add the variable terms to get the equivalent equation.

Equivalent equation is an equation which looks different but the result will be same.

14x-8 = 100.

Add 8 on both sides.

14x=100+8

14x=108.

Hence, 14x=108 is the equivalent equation of the equation 16x – 8 + 2x = 100.

[tex]x=-\frac{261}{46}[/tex]

Step-by-step explanation:

we have the expression

[tex]\frac{3x+2y-5z}{y-4z}=\frac{x}{3y}[/tex]

we have

[tex]y=6,z=-\frac{1}{2}[/tex]

To find the value of x, substitute the given values of y and z in the expression

[tex]\frac{25}{48}[/tex] represents repeating decimal

Solution:

We are asked to find the rational number that represents repeating decimal

A repeating decimal, also called a recurring decimal, is a number whose decimal representation eventually becomes periodic (i.e., the same sequence of digits repeats indefinitely)

Option 1

[tex]\frac{11}{40} = 0.275[/tex]

So here the decimal part is not repeating. So [tex]\frac{11}{40}[/tex] does not represent repeating decimal

Option 2

[tex]\frac{3}{25} =0.12[/tex]

So here the decimal part is not repeating. So [tex]\frac{3}{25}[/tex] does not represent repeating decimal

Option 3

[tex]\frac{25}{48} = 0.52083333333[/tex]

So here in decimal part "3" is repeating and goes on forever

So [tex]\frac{25}{48}[/tex] represents repeating decimal

Option 4

[tex]\frac{7}{32} = 0.21875[/tex]

So here the decimal part is not repeating. So [tex]\frac{7}{32}[/tex] does not represent repeating decimal

Answer:

White.

Step-by-step explanation:

Theoretical probabilities are:

Red: 5 / ( 5 + 6 + 5) = 5/16

White: 6/16 = 3/8.

Blue:  5/16.

The answer is white because it is drawn 12 times which equals its  theoretical probability: 12/32 = 3/8.

The probability of drawing the color the same as the theoretical probability is 3/8.

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

Given:

A bag contains 5 red, 6 white, and 5 blue marbles.

Theoretical probabilities for the colors are:

Red:

= 5 / ( 5 + 6 + 5)

= 5/16

White:

= 6/16

= 3/8.

Blue:  5/16.

So, the probability of drawing the color the same as the theoretical probability  is white because the theoretical probability is 3/8.
