Step-by-step explanation:
calc
Answer:
17.5Step-by-step explanation:First multiply 7 (seven) and 15 (fifteen) and once you get your answer for that (which is 105) then you divide 6 by that number. which is when you will get your answer, which is 15.5.
7(15)= 105
105/6= 17.5
Which representation does NOT show Y as a function of X?
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)

What is the simplest form of the expression (14.2a + 9.8b) – (13.1b – 0.2a) – (3.7a + 4.8b)?
A. 10.7a – 8.1b
B. 10.7a + 27.7b
C. 18.1a - 8.1b
D. 18.1a + 27.7b
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

Which equation combines with the given equation solution x = 3 and y = 9? X + 2y = 21 A. 4x + 6y = 64 B. 2x + y = 36 C. 4x + y = 21 D. -3x + 4y = 33 E. 3x + 2y = 28
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

Pls help I will give brainliest . The answer choices are
x=45, y=90
x=45, y=25
x=57, y=25
x=57, y=90
Answer:
The answer is B
Step-by-step explanation:
Answer:
C. x = 57, y = 25Step-by-step explanation:
∠LKU = 1/2∠EKU ⇒ ∠LKU = 1/2(90°) = 45°
(x - 12)° = 45°x = 57°∠KCE = 90° as diagonals of a square are perpendicular
(4y - 10)° = 90°4y = 100°y = 100°/4y = 25°Correct option is C. x = 57, y = 25

Estimate.Show how you estimated
219÷2=
can you guys plz help me I need to find the estimate.
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: [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]

two customers went to a dry cleaners to get clean their shirts and pants. Each shirt cleaning costs the same amount, and each pants cleaning costs the same amount. The first customer paid $30.00 for 5 shirt cleanings and 3 pants cleaning. The second customer paid $29.00 for 3 shirt cleanings and 4 pants cleaning. What was the cost, in dollars, of each shirt cleaning?
Answer:
$3.00
Step-by-step explanation:
5x + 3y = 30 - - - - - 1 x 4
3x + 4y =29 - - - - - -2 x 3
--------------------------------------------
20x +12y = 120 - - - - 3
9x + 12y = 87 - - - - - 4
--------------------------------------------
3-4
20x - 9x= 120 - 87
11x = 33
X= 33
11
X = 3
The cost of cleaning each shirt is 3 dollars.
What is a linear equation?A linear equation is an algebraic equation of degree one. In general, the variable or the variables(in the case of a linear equation in two variables) the variables are x and y.
Assuming the cost of cleaning 1 shirt is x and the cost of cleaning 1 pant is y.
The first customer paid $30.00 for 5 shirt cleanings and 3 pants cleaning.
∴ 5x + 3y = 30...(i)
The second customer paid $29.00 for 3 shirt cleanings and 4 pants cleaning.
∴ 3x + 4y = 29...(ii)
Now to cancel out 'x' in both equations we multiply eqn(i) by 3 and eqn(ii) by 5.
So, 15x + 9y = 90...(iii) and 15x + 20y = 145...(iv)
Now subtracting (iii) from (iv) we get 11y = 55 ⇒ y = 5 and substituting the value of y in eqn(iv) we get x = 3.
The cost of cleaning each shirt is 3 dollars.

What is the vertex for the equation f (x) = 6(x – 10)2 – 4?
Answer:
(10, -4)Step-by-step explanation:
The vertex form of the equation of quadratic function with vertex (h, k) is:
f(x) = a(x - h)² + q
f(x) = 6(x - 10)² - 4 - given function
so:
a = 6, h = 10, q = -4

PLZ PLZ PLZ HELP I WILL GIVE BRAINLIEST PLZ HELP AND READ ALL QUESTIONS REMEMBER GOD IS GOOD.
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.
A graphic artist created the design for a rectangular poster. The design is 12 inches by 9 inches. The poster is 48 inches by 36 inches
What scale factor did the graphic artist use to create the design?
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
