Write the slope-intercept form of the equation of the line (1,-4) with a slope of -2
Answers
Answer:
B
Step-by-step explanation:
General equation
y = mx + b
m = the slope
b = the y intercept
Slope
y = -2x + b
y intercept
use the point to get the y intercept.
x = 1
y = - 4
Subsitute these values into the incomplete equation under slope
-4 = -2(1) + b
-4 = - 2 + b Add 2 to both sides
-4+2 = b
b = - 2
Answer
y = -2x - 2
Answer:
y = -2x - 2
Step-by-step explanation:
When given a point and a slope, we use slope-intercept formula:
y - y1 = m (x - x1)
m = slope point: (1,-4)
y - y1 = m (x - x1)
y - (-4) = -2 (x - 1)
y + 4 = -2x + 2
- 4 - 4
y = -2x - 2

The amount of money in a saving account increase from $250 to $270 what is the precent increase of the money in the savings account
Answers
Answer:
8%
Step-by-step explanation:
percent increase = [ (difference between initial value and final value) ÷ initial value] x 100
⇒ percent increase = [ (270 - 250) ÷ 250] x 100 = 8%
Answer:
12.5
Step-by-step explanation
270 - 250 = 20
250 divided by 20 = 12.5
So therefore the percentage in the increase is 12.5

A parallelogram is cut out of a 12-inch by 8-inch sheet of paper. There are four right triangle remnants. Two have the dimensions 2 inches by 9 inches, and the other two have the dimensions 3 inches by 6 inches.
A parallelogram is shown. An altitude is drawn from one point to the opposite side to form a right angle. The length of the base is 9.22 inches.
The resulting parallelogram has a base of approximately 9.22 inches.
Complete the following steps to calculate the altitude of the parallelogram using area methods.
The area of the sheet of paper is
square inches.
The combined area of the triangle cutouts is
square inches.
The area of the parallelogram is
square inches.
The altitude of the parallelogram rounded to two decimals is
square inches.

The area of a shape is the amount of space it occupies.
The area of the paper is 96 square inchesThe combined area of the triangle cutouts is 36 square inchesThe area of the parallelogram is 60 square inchesThe altitude of the parallelogram is 6.51 inchesThe area of the paperThe dimension of the paper is given as: 12-inch by 8-inch
So, its area is:
[tex]Area = 12 * 8[/tex]
[tex]Area = 96[/tex]
Hence, the area of the paper is 96 square inches
The area of the trianglesThe dimensions of the 4 right triangles are: Two 2 inches by 9 inches, and two 3 inches by 6 inches
So, the combined area is:
[tex]Area = 0.5(2 * 2 * 9 + 2 * 3 * 6)[/tex]
[tex]Area = 36[/tex]
Hence, the combined area of the triangle cutouts is 36 square inches
The area of the parallelogramThe area of the parallelogram is the difference between the areas of the paper and the four right triangles.
So, we have:
[tex]Area = 96 - 36[/tex]
[tex]Area = 60[/tex]
Hence, the area of the parallelogram is 60 square inches
The altitude of the parallelogramThe base is given as 9.22
So, we have:
[tex]Area = Base * Altitude[/tex]
This gives
[tex]60 = 9.22* Altitude[/tex]
Divide both sides by 9.22
[tex]Altitude = 6.51[/tex]
Hence, the altitude of the parallelogram is 6.51 inches

A. 7
B. 3
C. 3.5
D. 1.5
Answers
Answer: 3.5
Step-by-step explanation:
It is an intersection of a tangent and a secant.
122=9(9+2a)
144=81+18a63= 18a3.5=a
Took test as well!
The numerical value of 'a' in the secant segment of the circle is 3.5.
What is the numerical value of 'a'?The secant-tangent power theorem states that "if a tangent and a secant are drawn from a common external point to a circle, then the product of the length of the secant segment and its external part is equal to the square of the length of the tangent segment."
It is expressed as:
( tangent segment )² = External part of the secant segment × Secant segment.
From the diagram:
tangent segment = 12 ft
The external part of the secant-segment = 9 ft
Secant segment = ( a + a + 9 ) = 2a + 9
To determine the value of 'a', we use the secant-tangent power theorem.
12² = 9 × ( 2a + 9 )
Solve for 'a':
144 = 18a + 81
144 - 81 = 18a
63 = 18a
a = 63/18
a = 3.5
Therefore, 'a' has a value of 3.5.
Option C) 3.5 is the correct answer.

6x - 3(2x) -3(4) = - 12 Distributive property
6x - 6x - 12 = - 12
(6x - 6x) -12 = - 12 like terms together
