Which system of equations has no solutions?


— Please help :(

Answer:

$36 for the jacket

Answer:

C y= 2x +2

Step-by-step explanation:

Look at the graph and look at the dots. For example if you look at negative 1 on the x-axis there is a dot there. so it now you count up to where you see the next dot on the y-axis. Which it goes up 2, then count to the right towards the Y-Axis which is one. now you left with 2/1. since it is going up 2 it will be positive and 2 over 1 is simplified so you are left with 2x and the B will be 2 because the line goes through 2 on the y-axis. This equation should help you y=mx+b m is the slope and B is the y axis

Answer:

they are both correct, all sides are equal to eachother yknow?

Step-by-step explanation:

Answer:

R (27, 8)

Step-by-step explanation:

The coordinate plane is a two-dimensional plane consisting of the y axis (vertical line) and x-axis (horizontal line). The origin is known as the zero point (reference point) is the intersection of the x axis and y axis.

A point on the coordinate plane is represented by (x, y) where x is the x coordinate and y the y coordinate.

Given point Q = (18, 5), the x coordinate is 18 and the y coordinate is 5.

Let the location of point R = (a, b)

a = x-coordinate of point Q + 1/2 of x-coordinate of point Q = 18 + (1/2)*18 = 27

b = y-coordinate of point Q + 3 = 5 + 3 = 8

Therefore R = (27, 8)

Answer:

I put B and A= 25

I got it on another website but I'm not entirely sure.

The square is asymmetrical quadrilateral, which implies it has 4 equal sides and angles. This can also be described as a rectangle having two neighboring sides that are both the same length.

It ensures that the elements are perpendicular, either at right angles to one another.

The length of the square pen is [tex]\sqrt{A}[/tex], and the perimeter should be no more than 100  then the perimeter of a square is 4a the over is [tex]a^2[/tex]  So, the equation :

[tex]\to 4\sqrt{A}=100\\\\ \to \sqrt{A}=\frac{100}{4}\\\\\to \sqrt{A}=25[/tex]

Therefore, the final answer is "25".

Answer:

60 students 140 adults

Step-by-step explanation:

so 200 into 3 : 7

first we just do this: 200 ÷ (3+7) = 200 ÷ 10 = 20

so a 1 in the ratio is 20 people

and theres 3 : 7

so 3 * 20 = 60

7 * 20 = 140

60 kids to 140 adults

Answer:

140 are students

Step-by-step explanation:

let k = number of kids

set up proportion based on 7 out of 10 are kids

7/10 = k/200

cross-multiply: 10K = 1400

Answer:

The member of the art museum can visit 22 times

Step-by-step explanation:

BC= 12cm

AC = 5cm

According to Pythagoras theorem ,

12^2 + 5^2 = AB^2

144+25 =169 ..

so AB^2 = 169

AB=√169 ..

Therefore, AB= 13cm ..

Answer:

15 rentals

Step-by-step explanation:

Latest Releases Depot

rent = $3 per DVD

membership= free

let the number of DVD be x

let the expression for the total be

y= 3x----------------1

Video for You

rent= $2  per DVD

membership= $15

let the number of DVD be x

let the expression for the total be

y= 15+2x----------------2

equate 1 and 2

3x=15+2x

collect like terms

3x-2x=15

x= 15

Hence the number of DVDs needed for the two rentals to have the same amount is at least 15 rentals

Answer:

6.7234724... ; ✓7

Step-by-step explanation:

In the most simplest of terms, we can explain irrational numbers as numbers which cannot be expressed as a ratio of two integers usually because they cannot give an exact value when evaluated.

Using the values given :

6.7234724... - - >This is an irrational number because the '...' depicts that the values are unending and as such an exact expression in the form of a ratio (p/q) cannot be determined.

315, 26, 17, 8 - - - > Is a rational number, it could be express in ratio form as : 315/1. 315 is an integer and all integers are rational.

-0.25 - - > it could be expressed as - 1 /4. Hence it is a rational number.

✓7 - irrational as the simplification gives : 2.6457513...

Answer:

x°=48°

Step-by-step explanation:

angle Y=x°

angle Z= angle y, because equal side of the angles are equal.

so, angle X +angleY+ angle Z=180° ( angle sum property of triangles)

therefore 84°+x°+x°=180°

2x°=180° -84°

2x°=96°

x°=48°

Answer:

Step-by-step explanation:

1. X + y

Putting values of x and y

-7 + (-3)

= - 10

2. xy

Putting values of x and y

(-7)(-3)

= 21

3. x2 + y2

Putting values of x and y

= (-7)2 + (-3)2

= 49 + 9

= 58

Answer: x= 18

Step-by-step explanation:

3x - 16 = 38

38 + 16 = 54

3x/3 = 54/3

X= 18

Step-by-step explanation:

[tex] \tt{3x - 16 = 38}[/tex]

We want to remove the 16 first. So , Since the original equation is - 16 , we are going to use the oppsite operation and add 16 to both sides.

⟶ [tex] \tt{3x - 16 + 16 = 38 + 16}[/tex]

Simplify ! - 16 + 16 = 0 on the left. 38 + 16 = 54 on the right.

⟶ [tex] \tt{3x = 54}[/tex]

Now , we need to think how to remove the coefficient 3. Since the opposite of multiplication is division , we are going to divide both sides by 3.

⟶ [tex] \tt{ \frac{3x}{3} = \frac{54}{3}} [/tex]

Simplify ! 3 / 3 = 1 on the left and 54/3 = 18 on the right . So, our answer is 18.

[tex] \pink{ \boxed{ \boxed{ \tt{Our \: final \: answer : \boxed{ \underline{ \tt{x = 18}}}}}}}[/tex]

Hope I helped ! ♡

Have a wonderful day / night ! ツ
