PLEASE HELLP ME! I would appreciate if you can!!

8ºC below 0 is -8ºC (negative eight degrees celsius).

Below means subtract. 0 - 8 = -8.

Answer:

C. 4x + y = 21

Step-by-step explanation:

X + 2y = 21

A. 4x + 6y = 64

B. 2x + y = 36

C. 4x + y = 21

D. -3x + 4y = 33

E. 3x + 2y = 28

x = 3

y = 9

X + 2y = 21

3 + 2(9) = 21

3 + 18 = 21

21 = 21

A. 4x + 6y = 64

4(3) + 6(9) = 64

12 + 54 = 64

66 is not = 64

B. 2x + y = 36

2(3) + 9 = 36

6 + 9 = 36

15 is not = 36

C. 4x + y = 21

4(3) + 9 = 21

12 + 9 = 21

21 = 21

Answer:

110

Step-by-step explanation:

219 divided by 2 equals 109.5, so you basically just round to the nearest whole number. You should get 110, thus, your answer. Of course, you could just leave it as 109.5, but if you want it estimated, or simplified, the information above should help.

Hope this helps!

Answer:

D

Step-by-step explanation:

A function is valid if each x input has a different y counterpart

In picture D both 3 and 5 repeat --> (3,2)(2,6) and (5,6)(5,8)

This would create an undefined line that would fail the vertical line test (multiple x values on one y value)

Answer:

The answer is B

Answer:

Step-by-step explanation:

∠LKU = 1/2∠EKU ⇒ ∠LKU = 1/2(90°) = 45°

∠KCE = 90° as diagonals of a square are perpendicular

Correct option is C. x = 57, y = 25

Answer:

The answer is x=-7

Step-by-step explanation:

To find the x divide both side by -4

-4x = 28

-4x/-4=28/-4

x= -7

Answer:

perpendicular line: y = -[tex]\frac{1}{4}[/tex]x - [tex]\frac{9}{4}[/tex]

parallel line: y = 4x - 15

Step-by-step explanation:

Perpendicular line:

A perpendicular line to y = 4x-3 would have a slope that is the negative reciprocal (flip the fraction and add a negative sign). The negative reciprocal of 4 is - [tex]\frac{1}{4}[/tex].

Now that we have our slope, we can plug the given point of (3, -3) into the slope-intercept equation to find b.

-3 = - [tex]\frac{1}{4}[/tex](3) + b

-3 = - [tex]\frac{3}{4}[/tex] + b

Add [tex]\frac{3}{4}[/tex] to each side of the equation to isolate b.

-[tex]\frac{9}{4}[/tex] = b

Now we can write our equation, y = -[tex]\frac{1}{4}[/tex]x - [tex]\frac{9}{4}[/tex]

Parallel Line:

A parallel line to y = 4x-3 has the same slope. To find the equation, plug the slope and given point (3, -3) into the slope intercept equation and solve for b.

-3 = 4(3) + b

-15 = b

Now you can write the equation, y= 4x -15

Answer: 6/7 is the slope

Answer: Let's solve your equation step-by-step.

yy=59(45)

Answer:

y=5 or y=−5

Answer:

y = 25

Step-by-step explanation:

y = 5/9 x, x = 45

y = 5/9 × 45

y = 5 × 5

y = 25

Answer:

-4.5

Step-by-step explanation:

-9/2= -4.5

Answer:

B. y = -4. Slope is 0

Answer: [tex]y=\frac{1}{2} x+2[/tex]

Step-by-step explanation:

The format for these equations are y=mx+b. Find the slope, which is the change in y over the change in x. When you apply this formula, you get 1/2. To find the y-intercept, just count from the origin to the place the line meets the y-axis, which is 2. Putting it together, you get the equation [tex]y= \frac{1}{2}x+2[/tex]

Answer:

A) 10.7a - 8.1b

Step-by-step explanation:

(14.2a + 9.8b) - (13.1b - 0.2a) - (3.7a + 4.8b)

Combine like terms.

(14.2a + 0.2a - 3.7a) = 10.7a

(9.8b - 13.1b - 4.8b) = -8.1b

Answer:

10.7a – 8.1b

Step-by-step explanation:

Answer:

1) The amount the family spent on pizza is $300

2) The amount the family spent on soda is $43.2

3) The amount the family spent in all is $343.2

Step-by-step explanation:

The number of pizzas bought by the family = 24

The price of each pizza = $12.50

The number of bottles of soda the family bought = 36

The price of each bottles of soda = $1.20

1) The amount the family spent on pizza = 24 × $12.50 = $300

2) The amount the family spent on soda = 36 × $1.20 = $43.2

3) The amount the family spent in all = The amount the family spent on pizza + The amount the family spent on soda

∴ The amount the family spent on soda = $300 +$43.2 = $343.2.

Answer:

4

Step-by-step explanation:

Step one:

given data

The design is 12 inches by 9 inches.

[tex]length = 12 in\\\\width = 9 in[/tex]

The poster is 48 inches by 36 inches

[tex]length = 48in\\\\width = 36 in[/tex]

Step two:

divide the dimension of the poster by the dimension of the design to get the scale factor

[tex]L= 48/12= 4\\\\W= 36/9= 4[/tex]

Hence the scale factor is 4
