Answer:
y = 2.5x - 8
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 2.5 and c = - 8 , then
y = 2.5x - 8 ← equation of line

A smartphone has a screen that has a width of x and a height that is 1.8 times the width. The outer dimensions of the phone are shown.
Write an expression for the portion of the phone that is not occupied by the screen. Assume that the phone is rectangular.
Answer: 4.8x+3
Step-by-step explanation:
The portion of the phone that is not occupied by the screen is 4.9x + 3 cm².
What is Surface Area?For each three-dimensional geometrical shape, surface area and volume are determined. The area or region that an object's surface occupies is known as its surface area. Volume, on the other hand, refers to how much room an object has. There are numerous shapes and dimensions in geometry, including sphere, cube, cuboid, cone, cylinder, etc. Each form has its own volume and surface area. Nevertheless, we can only estimate the area that two-dimensional figures like a square, circle, rectangle, triangle, etc. cover; there is no volume available.
As per the given data:
The width of the screen = x cm
Height of the screen = 1.9 times the width = 1.9x
Dimensions of the phone are given in the diagram.
The area of the screen = height × width
= 1.9x × x = 1.9x² cm²
The area of the phone = (1.9x + 3)(x + 1)
= 1.9x² + 1.9x + 3x + 3
= 1.9x² + 4.9x + 3 cm²
Area of the phone not occupied by screen:
= area of the phone - area of the screen
= 1.9x² + 4.9x + 3 - 1.9x²
= 4.9x + 3 cm²
Hence, the portion of the phone that is not occupied by the screen is 4.9x + 3 cm².

(9x + 5)
(12x - 19)
Answer: x=8 angle BDC=77
Step-by-step explanation:
9x-12x=-19-5
-3x=-24
x=8
12x(8)-19
=77
(9x + 5) and (12x - 19) are one angle split equally.
(9x + 5) = (12x - 19)
The value of m∠BDC is 65°
What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles are equal to 180 degrees.
We have,
(9x + 5) and (12x - 19) are one angle split equally.
So,
9x + 5 = 12x - 19
We will solve for x.
9x + 5 = 12x - 19
Add 19 on both sides.
9x + 5 + 19 = 12x
Subtract 9x on both sides.
24 = 12x - 9x
24 = 3x
Divide both sides by 3.
24/3 = x
x = 7
Now,
The value of m∠BDC.
= 12x - 19
= 12 x 7 - 19
= 84 - 19
= 65°
Thus,
The value of m∠BDC is 65°

A cell phone provider offers a plan that costs $20 per month plus $0.20 per text message sent or received. A comparable plan costs
$30 per month but offers unlimited text messaging. Complete parts a. and b. below.
a. How many text messages would have to be sent or received in order for the plans to cost the same each month?
In order for the plans to cost the same.
text messages would have to be sent or received
b. If you send or receive an average of 200 text messages each month which plan would you choose and why?
Answer:
Step-by-step explanation:
a)
30=20+0.2m
10=0.2m
50=m
So after sending 20 messages the plans would cost the same.
b)
Obviously from the first part that the unlimited plan is cheaper when sending 200 messages, but the costs numerically would be.
Unlimited plan costs $30 while the other plan costs
20+0.2(200)=$60

How would you express the area of the rectangle using the Distributive Property?
Answer:
C
Step-by-step explanation:
Step 1: Find your legth and width
Length = x + 5
Width = 3
Step 2: Use area formula to find area
l x w = A
(x + 5) x 3 = A
A = 3(x+5)
Step 3: Therefore Statement
Thereforethe answer to the question is C. 3(x+5)
Answer:
C. 3(x + 5)
Step-by-step explanation:
area of rectangle = length * width = width * length
A = area of largest rectangle
a1 = area of left rectangle
a2 = area of right triangle
The largest rectangle is made up of the the two smaller rectangles.
A = a1 + a2
Left rectangle: a1 = WL = 3x
Right rectangle: a2 = WL = 3 * 5
Total area of the two small rectangles:
A = a1 + a2 = 3x + 3 * 5
Apply the distributive property in reverse to 3x + 3 * 5 by factoring out a 3:
A = 3x + 3 * 5 = 3(x + 5)
The area of the largest rectangle is 3(x + 5)
We can also find an expression for the area of the largest rectangle directly by looking at its length and width.
The length of the largest rectangle is x + 5.
The width of the largest rectangle is 3.
A = WL
Substitute 3 for W, the width.
Substitute x + 5 for L, the length.
A = 3(x + 5)
Answer: C. 3(x + 5)

An irrational number cannot be written as a simple fraction and the decimals would keep on going without a pattern (if it was repeating, it would be rational).
Answer:
If the legs are equal to 4 cm and 5 cm, respectively we can rewrite the equation 42+52=c2 -> 16+25=41=c^2 so then, c= the square root of 41, which is an irrational number.

Wind farms are a source of renewable energy found around the world. The power P (in kilowatts) generated by a wind turbine varies directly as the cube of the wind speed v (in meters per second). If a turbine generates 700 kW in a 12 m/s wind, how much power does it generate in a 6 m/s wind?
(The formula for P as a power function of v is P = a ⋅ v3.
A. 88 kW
B. 175 kW
C. 125 kW
D. 1050 kW
Answer:
New power = 88 Kw (Approx.)
Step-by-step explanation:
Given:
P = a(v³)
Old power p = 700 Kw
Old wind speed v = 12 m/s
Find:
New power when v = 6m/s
Computation:
P = a(v³)
700 = a(12³)
a = 0.4050 m²
New power = a(v³)
New power = (0.4050)(6³)
New power = 87.48
New power = 88 Kw (Approx.)
