Um, can you add the picture of the number line?

Given:

The given system of equations is:

[tex]2x+y=1[/tex]

[tex]x-2y=8[/tex]

To find:

The solution to this system of equations by graphing.

Solution:

We have,

[tex]2x+y=1[/tex]

[tex]x-2y=8[/tex]

The table of values for first equation is:

x       y

0      1

1      -1

Plot the points (0,1) and (1,-1) on a coordinate plane and connect them a straight line.

The table of values for second equation is:

x       y

0      -4

2      -3

Plot the points (0,-4) and (2,-3) on a coordinate plane and connect them a straight line.

The graphs of given equations are shown in the below figure.

From the below figure, it is clear that the lines intersect each other at point (2,-3). So, the solution of the given system of equations is (2,-3).

Therefore, the solution to this system of equations is:

x-coordinate: 2

y-coordinate: -3

Answer:

Mean: 17.6 Median: 18 Mode: N/A Range: 27

Step-by-step explanation:

To solve for m, divide both sides by 5/6

M = 85/ 5/6

When dividing by a fraction flip the fraction over and multiply

M = 85 x 6/5 = (85 x 6)/5 = 510/5 = 102

Answer:

6.50 + 5.75n

Step-by-step explanation:

6.50 for the first hour only being charged once and the 5.75 being for the number of hours (n) she works after the first hour

Answer:

B

Step-by-step explanation:

n is how many additional hours after the first hour she babysits. She charges $5.75 for each additional hour. So, that would be:

5.75n

But for the first hour, she charges 6.50. So that would be:

6.50+5.75n

Step-by-step explanation:

Given

w(x) = - 3x - 4

Now

w(7) = - 3 * 7 - 4

Answer:

The number is -3.

Step-by-step explanation:

Set up an equation:

Variable n = number

12 + 7n = n - 6

Assuming the question is solve for n, isolate the variable:

Subtract n from both sides:

12 + 6n = -6

Subtract 12 from both sides:

6n = -18

Divide by 6 on both sides:

n = -3

Check your work:

12 + 7(-3) = -3 - 6

12 - 21 = -3 - 6

-9 = -9

Correct

Answer:

176.4

Step-by-step explanation:

1.) 7/5 = surface area/90 = (7/5)^2 = 49/25

2.) sa/90 = 49/25

3.) 4,410/25a

Surface area is 176.4

Answer:

52

Step-by-step explanation:

Total Number of students :

Stage 3 : 380

Stage 4 : 240

Stage 5 : 110

Total = (380 + 240 + 110) = 730

Number of samples required = 100

Number of key stage 3 students required :

(Key stage 3 / total) * number of samples

(380 / 730) * 100

= 0.5205479 * 100

= 52.0547

= 52

Answer:

B': (-12,15)

Step-by-step explanation:

Answer:

circumference=πd

3.142×(7.5+7.5)

3.142× 15

47.13

Answer:

C. the lines will be intersecting but neither parallel nor perpendicular

Step-by-step explanation:

changing the x coeficient means you're changing the gradien/ slope. so it will intersecting in one point of y if the x = 0

y = 2x + 4

y = 2(0) + 4 = 4

y = 3x + 4

y = 3(0) + 4 = 4

Answer:

Step-by-step explanation:

If you type this equation onto the graphing calculator you can clearly tell the lines intersect therefore the right answer is the last one.

Answer:

h=8

Step-by-step explanation:

a²+b²=c²

a=A

b=12

c=13

therefore substitute

A²+(12)²=(13)²

A²=13²-12²

A²=25

A=5

h=3+A

h=3+5

h=8

Answer:

8 ft

Step-by-step explanation:

since it is a right angled triangle and you have 2 side lengths, we use the pythagoras theorem here.

a² + b² = c²

the c² is always your hypotenuse (longest side of the triangle, also opposite to the right angles)

*the b and a doesnt matter which order you put it in*

so; (sub in the numbers to the formula)

a² + 12² = 13²

(rearrange - like terms together)

a² = 13² - 12²

(calculate it)

a² = 25

(simplify it - get rid of the ² on the a)

a = √25

(solve)

a = 5

so, we know that a = 5 and we know that we have an additional 3

5 + 3 = 8
