P = 2L + 2w
344 = 2L + 2·74
344 - 148 = 2L
2L = 196
L = 196 : 2
L = 98 yards
y = 40 + 90x. Which statement represents the meaning of each part
of the function?
(1) y is the total cost, x is the number of months of service,
$90 is the installation fee, and $40 is the service charge per
month.
(2) y is the total cost, x is the number of months of service,
$40 is the installation fee, and $90 is the service charge per
month.
(3) x is the total cost, y is the number of months of service,
$40 is the installation fee, and $90 is the service charge per
month.
(4) x is the total cost, y is the number of months of service,
$90 is the installation fee, and $40 is the service charge per
month.
Answer:
Option (2).
Step-by-step explanation:
A satellite T.V. company charges one time installation fees along with monthly service charge.
Total cost is modeled by the function y = 40 + 90x
Here y = Total cost charged by the company
A one time installation charges = $40
Service charge for a month = $90
and number of months for which service was used = x months
Therefore, Option (2) explains the function well.
(8 ∙ 4) - One-half (10 + 12 + 16)
(8 ∙ 4) - (10 + 12 + 16)
(8 ∙ 4) - One-half (5 + 6 + 8)
(8 ∙ 4) - (5 - 6 - 8)
Based on the coordinate plane, a mathematical expression which can be used to find the area of triangle RST is: A. [(8 × 4) - 1/2 × (10 + 12 + 16)].
A triangle can be defined as a two-dimensional geometric shape that comprises three (3) sides, three (3) vertices and three (3) angles only.
Mathematically, the area of the triangle is given by the formula:
In this scenario, the mathematical expressions that would be used to find the area of triangle RST with points (-5, 6), (3, 4) and (-2, 2) are given by:
Area of rectangle = LW = 8 × 4
Area of triangle 1 = 1/2 × (2 × 5) = 1/2 × 10
Area of triangle 2 = 1/2 × (3 × 4) = 1/2 × 12
Area of triangle 3 = 1/2 × (2 × 8) = 1/2 × 16
The area of triangle RST = [(Area of rectangle) - 1/2 × (Area of triangle 1 + Area of triangle 2 + Area of triangle 3)].
Substituting the parameters into the formula, we have;
The area of triangle RST = [(8 × 4) - 1/2 × (10 + 12 + 16)]

Help me please
Answer: z=56
Step-by-step explanation:
Based on the figure, we can determine that 3y+8=68 and 4x=2z. With the knowledge that a trapezoid has 360°, we can first find the value of y to get the angle measures of the top angles. We can then subtract that from 360°.
3y+8=68 [subtract both sides by 8]
3y=60 [divide both sides by 3]
y=20
We now know the value of y is 20, but that is not relevant to solving this problem because we already know that the top angles are 68° each. So, we can subtract that from 360.
360-68-68=224
Now, we know that the bottom 2 angles have to add up to 224. Therefore, we can come up with 2 equations.
Equation 1: 4x=2z
Equation 2: 4x+2z=224
We can manipulate Equation 1 to be . Once we plug that into Equation 2, we can find the value of z.
[multiply]
[add]
[divide both sides by 4]
Now, we know that z=56.
