My teacher said to do an number line with it :(

Answer:

7

Step-by-step explanation:

We have that x1=−1, y1=5, x2=3, y2=7.

Plug the given values into the formula for a slope: m=7−(5)3−(−1)=12.

Now, the y-intercept is b=y1−mx1 (or b=y2−mx2, the result is the same).

b=5−(12)(−1)=112

Finally, the equation of the line can be written in the form y=b+mx:

y=112+x2

Answer:

X=6

Step-by-step explanation:

5(x-1)+3x=7(x+1)

5x-5+3x=7x+1

8x-5=7x+1

8x-7x=1+5

X=6

So the answer is X=6

Answer: 17/18

Step-by-step explanation: Multiply the amount of containers and the amount of cups in each container. Subtract 3. This is 51 out of 54, simplify this and get 17 out of 18.

Answer:

the answer is 1/18

Step-by-step explanation:

6×9=54-3=51.

One third and two thirds are too large for the amount he ate, so is 17/18s.

Answer:

Step-by-step explanation:

Answer:

a=$10

c=$3

Step-by-step explanation:

Step one:

given data

let adults tickets be a

and child tickets be c

so

Roy's purchase

6a+2c=66------1

Elisa's purchase

5a+4c=62-------2

Hence,  the system of equations

6a+2c=66------1

5a+4c=62-------2

solving simultaneously

6a+2c=66------1 x2

5a+4c=62-------2 x1

  12a+4c=132

 -5a+4c=62

   7a=70

divide both sides by 7

a=$10

put  a=70 in 1

6(10)+2c=66------1

60+2c=66

2c=66-60

2c=6

c=$3

Answer:

Fraction: [tex]\frac{27}{8}[/tex]

Mixed Number: [tex]3\frac{3}{8}[/tex]

Step-by-step explanation:

We know how much strawberry jam there is, which is 3/4 of a jar. But we need to find how many jars the raspberry jam can fill. We are told that it is      4 1/2 times as much as the strawberry jam. So, you mulitly 3/4 and 4 1/2 to get [tex]\frac{27}{8}[/tex] or [tex]3\frac{3}{8}[/tex].

ANSWER: [tex]\frac{27}{8}[/tex] or [tex]3\frac{3}{8}[/tex].

Answer:

b

Step-by-step explanation:

Answer:

B. [tex] n = 16p [/tex]

Step-by-step explanation:

number of ounces = n

number of pounds = p

There are 16 ounces in 1 pounds (unite rate: 1 pounds = 16 ounces)

Therefore, there would be n ounces in p pounds

Set a proportion to find n.

16 : 1 = n : p

[tex] \frac{16}{1} = \frac{n}{p} [/tex]

Multiply both sides by p

[tex] \frac{16}{1} \times p = \frac{n}{p} \times p [/tex]

[tex] \frac{16 \times p}{1} = n [/tex]

[tex] 16p = n [/tex]

[tex] n = 16p [/tex]

Answer:

The correct approach is "a simple random sample".

Step-by-step explanation:

Some other four approaches do never use any of certain characteristics. So that is indeed the best decision.

Answer:

x=5

Step-by-step explanation:

5x + 36  = 2x + 51

5x -2x  =  -36 + 51

  3x     =        15

         15/3

x = 5

Answer:

  (x, y) = (1, -1)

Step-by-step explanation:

The augmented matrix of coefficients for these equations is ...

  [tex]\left[\begin{array}{cc|c}2&-5&7\\-2&4&-6\end{array}\right][/tex]

The row-reduction function of your calculator can find the solution to the system of equations. The result of using that function is ...

  [tex]\left[\begin{array}{cc|c}1&0&1\\0&1&-1\end{array}\right][/tex]

This tells you the solution is (x, y) = (1, -1).

Answer:

3 cm²

Step-by-step explanation:

Given that:

5/8 of rectangle = red

Let area of rectangle = x

Each piece = 1/16 of whole rectangle

Area of whole rectangle = 48 cm²

Area of each piece = 1/16 of 48

1/16 * 48cm²

= 48 / 16 cm²

= 3 cm²

Hence area of each piece = 3cm²

Answer:

6x+10-3x=55

6x-3x=10+55

3x=65

65÷3=21.6

Answer:

5/4

Step-by-step explanation:

First plot any2 points. Next count how many units it is High and Left/Right to get to the second point!

(Added your graph for further explaination :)

First, determine 2 points on the graph. I'd recommend to choose 2 points that are next to each other to make it easier.

Second, see how many units higher the first point you chose (on the left) is than the second point you chose (on the right). Say it is 3 units, then you mark a points 3 units above the first point.

Third, see how many units to the right the second point is to the first. If it is 5 units, you would go to the point you marked on the previous step, and move 5 units to the right. If you did it correctly, it should end up on the second point you chose. The segment you drew should kind of look like a box.

Now, make a proportion. Put how many units you rose in the second step at the top, and how many you ran at the bottom. Treat this like a fraction and simplify. You have your slope!

Going higher and to the right is the formula rise/run. How many units do you rise, how many do you go right? I recommend doing this when finding slope on a graph

Hope I helped!!!!!!!!!!!!! :)

Answer: Maybe you're internet is slow or something.

Step-by-step explanation:

Answer:

x = 17

Step-by-step explanation:

For the lines to be parallel, then

(8x - 31) and (6x + 3) are alternate angles and congruent, then

8x - 31 = 6x + 3 ( subtract 6x from both sides )

2x - 31 = 3 ( add 31 to both sides )

2x = 34 ( divide both sides by 2 )

x = 17

Answer:

Remove parentheses.

y-10=-3\times -2y−10=−3×−2

2 Simplify 3\times -23×−2 to -6−6.

y-10=-(-6)y−10=−(−6)

3 Remove parentheses.

y-10=6y−10=6

4 Add 1010 to both sides.

y=6+10y=6+10

5 Simplify 6+106+10 to 1616.

y=16y=16

Answer:

B

Step-by-step explanation:

The options in the question and the number line are shown in the image attached.

From the options, it is clear that the difference between the temperatures at 7:00 a.M. and 1:00 p.M is;

Temperature at 7:00 a.M - Temperature at 1:00 p.M

We can see from the number line that the temperature at 7:00 a.M = -4

Temperature at 1:00 p.M = 16

difference between the two temperatures = ∣(-4) - 16∣ = 20

x = 8

Step-by-step explanation:

Angle sum property of triangle states that the sum of interior angles of a triangle is 180°.

So,

[tex] \rm \longrightarrow 45 \degree + 80 \degree + (9x - 17) \degree = 180 \degree \\ \\ \rm \longrightarrow 125 + 9x - 17 = 180 \\ \\ \rm \longrightarrow 108 + 9x = 180 \\ \\ \rm \longrightarrow (108 - 108) + 9x = 180 - 108 \\ \\ \rm \longrightarrow 9x = 72 \\ \\ \rm \longrightarrow \dfrac{9}{9} x = \dfrac{72}{9} \\ \\ \rm \longrightarrow x = 8[/tex]
