I NEED HELP WITH THESE QUADRATIC FUNCTIONS PLEASE !!
Answer: Hey, I can help. Which problem?
Step-by-step explanation:
The monthly cost (in dollars) of water use is a linear function of the amount of water used (in hundreds of cubic feet, HCF). The cost for using 14 HCF of water is $33.79, and the cost for using 27 HCF is $55.24. What is the cost for using 18 HCF of water?
Answer:
The cost of using 18 HCF = $40.39
Step-by-step explanation:
A linear function is one that has a constant rate of change for all the values within the distribution. For a linear function, there is a constant, and that constant is known as the slope or gradient of the linear function.
Let us first calculate this constant (slope).
Let:
X₁ = 14 HCF, Y₁ = $33.79, X₂ = 27 HCF, Y₂ = $55.24, m = slope
[tex]m = \frac{Y_2-Y_1}{X_2 - X_1} \\m = \frac{55.24 - 33.79}{27-14} \\m = \frac{21.45}{13} \\m = 1.65[/tex]
at any two points on the linear function, the rate of change of the cost to HCF = 1.65
Now, Let X₃ = 18 HCF, Y₃ = cost for using 18 HCF
[tex]m = \frac{Y_3 - Y_1}{X_3-X_1} \\where\ m= 1.65\\1.65 = \frac{Y_3-33.79}{18-14}\\1.65 = \frac{Y_3 - 33.79}{4} \\6.6 = Y_3 - 33.79\\Y_3 =6.6+33.79\\Y_3 = 40.39[/tex]
Therefore, the cost of using 18 HCF = $40.39
N:B X₂ and Y₂ can also be used with X₃ and Y₃ to find Y₃. You can try it out, you should get the same result
find the slope please :)

What are the cordinates of the image of the point (11,1)after a translation 10 units down followed by a reflection over the y-axis
Answer:
(-11,-9)
Step-by-step explanation:
translate 10 units down: y value: 1-10=-9
reflect over y-axis: x-value becomes opposite: 11 becomes -11

The local newspaper has letters to the editor from 70 people. If this number represents 4% of all of the newspapers readers, how many readers does the newspaper
Answer:
1750
Step-by-step explanation:
We first find the rate
70/4
= 17.5
We know 17.5 is 1% of the people that read newspaper, we will multiply 17.5 by 100 as it would represent 100% of the people
17.5 * 100
= 1750
Which quadrilateral(s) fit the description: "The Diagonals are congruent". Check all that apply. *
1 point
Parallelogram
Rhombus
Square
Rectangle
Kite
Trapezoid
Isosceles Trapezoid
Answer:
Rhombus
Step-by-step explanation:
Another quadrilateral that you might see is called a rhombus. All four sides of a rhombus are congruent. Its properties include that each pair of opposite sides is parallel, also making it a parallelogram. In summary, all squares are rectangles, but not all rectangles are squares.

Which inequality describes all the solutions to 5(3-x)<-2x+6
Answer:
x < 3
Step-by-step explanation:
5(3 - x) < -2x + 6
Distribute;
15 - 5x < -2x + 6
Add 2x to both sides;
15 - 3x < 6
Subtract 15 from both sides;
-3x < -9
Divide both sides by -3
x < 3

What is the scale factor of triangle A to triangle D.
Answer:
the correct answer is isosceles
Answer:
When two shapes are similar, their corresponding angles will be the same. The angles are the same because the shape is still the same. You can tell from the order of the similarity statement which angles match up. In the example, angles A and D are the same (both letters are in written first), angles B and E are the same (both letters are written in the middle), and C and F are the same
Step-by-step explanation:
Similar triangles can be different sizes, so the lengths of the corresponding sides are not necessarily the same, but they are proportional. This means that the ratios of the corresponding sides are equal.
