How many solutions does the system of linear equations represented in the graph below have?

A) No solution
B) one solution
C) infinity many solutions
D) none of the above

Answer:

Step-by-step explanation:

Because in equation x-9y=12

If we put x=12 and y=0 then it satisfy equation. (12)-9(0)=12

So, (12,0) make equation

(3,-1) also make equation

(3)-9(-1)=12

(0,-4/3) also make equation

Because

0-9(-4/3)=12

Only (0,12) is not making

Beacuse

(0)-9(12) is not equal to 12

Answer:

1.The formula to convert Celsius to Fahrenheit is:

F = 1.8 C + 32

Multiply the Celsius temperature by 1.8.

Add 32 to this number.

Report the answer in degrees Fahrenheit.

Example: Convert 20°C to Fahrenheit.

F = 1.8 C + 32

F = 1.8 (20) + 32

1.8 x 20 = 36 so F = 36 + 32

36 + 32 = 68 so F = 68°F

20°C = 68°F

Answer:

Lateral surface area = 280 square inches

Step-by-step explanation:

Lateral surface area of a prism = (Perimeter of the base) × height of the prism

Perimeter of the base = 8 + 15 + 17

                                     = 40"

Height of the prism = 7"

Therefore, Lateral surface area of the prism = 40 × 7

                                                                         = 280 square inches

Step-by-step explanation:

There are 24 students in total. Total will also be the denominator. Add 6 + 7 to find the amount that play the sports. Insert the number (13) as the numerator. Divide 13 by 24 if you need to find the percent!

Answer: 11/24

Step-by-step explanation:

2+5+4 =11

Expect the 13 person/students didn't play

Total people 24

24-13=11

Answer:

Step-by-step explanation:

Triangles EFG and FGH are similar.

x/15 = 36/39

x/15 = 12/13

x = 15*12/13 = 180/13 ≈ 13.8 units

The required measure of x is given as 5.8 in the given triangle.

The triangle is a geometric shape that includes 3 sides and the sum of the interior angle should not be greater than 180°.

Similar triangles are triangle that has a relationship as of some scale factor.

here,
From the figure,
From triangle GHF and triangle EGF
x / 15 = 15 / 39
x = 225 / 39
x = 5.8

Thus, the required measure of x is given as 5.8 in the given triangle.

Answer:

C

Step-by-step explanation:

Remark

The easiest way to do this is to add the two givens together and then multiply by two. Why 2?  Because the formula is P = 2(L + W)

Givens

L = 8x - 2

W = 4x - 4

Solution

P = 2*(8x - 2 + 4x - 4)

P = 2*(12x - 6)

P = 24x - 12

Answer:

The answer is (-2,3)

Step-by-step explanation:

If you look at the coordinate plane, you'll notice that the x -values are negative and the y-values are positive. So, if you look at where the two lines meet, they meet at the point (-2,3).

Answer:

the discount is 43.35 or the final price $7.65

Step-by-step explanation:

Discount = Original Price x Discount %/100

Discount = 51 × 85/100

Discount = 51 x 0.85

You save = $43.35

Final Price = Original Price - Discount

Final Price = 51 - 43.35

Final Price = $7.65
