The line y=kx+4 goes through the point (2,-2)
Sketch the graph the line
Please write it step by step
Answers
The line of the graph y= kx +4 goes through the point (2,-2) is given by
y = -3x +4.
As given in the question,
Equation of the line is given by y = kx + 4
Passing through the point (2, -2)
Substitute the value in equation we get,
-2= k(2) + 4
⇒2k = -2 -4
⇒k =-6 /2
⇒k =-3
Equation of the line y= -3x + 4 sketched on graph passing through (2,-2).
Therefore, the line of the graph y = kx +4 goes through the point (2,-2) is given by y = -3x +4.

Explanation:
Start at -4 on the x axis.
Draw a vertical line until reaching the curve.
Then draw a horizontal line until reaching the y axis.
You should arrive at y = -5. This tells us f(-4) = -5
The input x = -4 leads to the output y = -5

How many times larger is (1.092 × 101) than (7 × 10−1)?
Answers
The number 1.092 × 10¹ is 15.6 times larger than 7 × 10⁻¹ .
A number is said to be in standard form if it can be written in a decimal number between 1.0 and 10.0 multiplied with power of 10.
For Example: 1.8x10² is a standard form .
In the given question
1.092×10¹ and 7×10⁻¹
both the numbers are in a standard form
For comparison we need to convert them in decimal form
1.092 × 10¹ = 1.092 x 10 = 10.92
7 × 10⁻¹ = 7/10 = 0.7
So , According to the question
Let 10.92 be x times larger than 0.7
which means
(0.7)*x=10.92
x=10.92/0.7
x=15.6
Therefore , 1.092 × 10¹ is 15.6 times larger than 7 × 10⁻¹ .

Three lakes lost water during a drought. lake jensen lost one sixth of its water, lake parlow lost 26% of its water, and lake stockton lost thirty three two hundredths of its water. which lake lost the least amount of water?
Answers
If three lakes lost water during a drought, lake Jensen lost one-sixth of its water, lake Parlow lost 26% of its water, and lake Stockton lost thirty-three two-hundredths of its water, then the lake that lost the least amount of water is lake Stockton.
The lake that lost the least amount of water can be determined by converting the amounts lost by each of the lakes into percentage form.
As lake Jensen lost one-sixth of its water, it can be written in percentage form as,
Lake Jensen = 1/6 × 100 = 100/6 = 16.67 %
As given, Lake Parlow lost 26%
Lake Parlow = 26%
As Lake Stockton lost thirty-three two-hundredths, it can be written in percentage form as,
Lake Stockton = 33/200 × 100 = 0.165 × 100 = 16.5 %
Thus, the least percentage of water lost is 16.5% by lake Stockton.

From the given statements, g(-13) = 20, that is option B, is true for g.

Further, g(0) = -2 and g(-9) = 6
Let us evaluate each option one by one-
A. g(7) = -1
As we can see x can take values only from -20 to 5. And 7 is greater than 5. This means that the function us not defined at g(7) and hence, option A is not the correct option.
B. g(-13) = 20
Here, x=-13 is in our domain and y = 20 also lies within our range. Hence, this is the correct option.
C. g(0) = 2
We are already given that g(0) = -2. y can take only one unique value for every value of x and hence, g(0) cannot be equal to 2.
D. g(-4) = -11
As we can see y can take values only from -5 to 45. And -11 is smaller than 5. This means that the function us not defined at g(-4) and hence, option D is not the correct option.

The dimensions of a basketball court are shown below. Suppose a player throws the ball from a corner to a teammate standing at the center of the court. a. If center court is located at the origin, find the ordered pair that represents the location of the player in the bottom right corner b. find the distance that the ball travels
Answers
The 94 ft. by 50 ft dimensions of the court obtained from a similar question posted online, gives;
a. The ordered pair representing the location of the player in the bottom right corner is (47, -25)
b. The distance traveled by the ball obtained using Pythagorean theorem, is approximately 53.2 feet.
How can Pythagorean theorem be used to find the distance the ball travels?The possible dimensions of a rectangular court obtained from a similar question posted online are;
Length of the basketball court = 94ft.
Width of the basketball court = 50 ft.
From the question, we have;
Location of the court center = The origin of a coordinate plane
a. The ordered pair that represent the location of a player in the bottom right corner is found as follows;
Let (x, y) represent the coordinates of the bottom right corner of the court, we have;
Horizontal distance from the center of the court (the origin) to the right boundary of the court, x = (94 ft.)/2 = 47 ft.
Vertical distance from the center to bottom of the court, y = (50 ft.)/2 = 25 ft.
Following the convention of points to the right and above the origin being positive, while points below the origin are negative, we have;
The ordered pair (the coordinates of the player) that represents the location of the player in the bottom right corner is therefore;
(x, y) = (47, -25)b. The distance, d, that the ball travels is given by Pythagorean theorem as follows;
d = √((47 - 0)² + ((-25) - 0)²) = √(2834) ≈ 53.2

the system of inequalities that represents the possible length in meters, l, and the possible width in meters, w, of the pool is given as w ≤ l - 10 and 2 l + 2 w > 62.

x - 10 ≥ width
w ≤ x - 10
w ≤ l - 10
Also, it is given that, the perimeter of the pool is more than 62 m
So, we get that:
P > 62
Also, we know that:
P = 2 l + 2 w

By using the property of vertically opposite angles the value x= 4 and the angle z = 78°
What are vertically opposite angles?
Vertical opposite angles are angles made at the intersection of two lines, these are non adjacent angles that are opposite to each other.
Vertical opposite angles are equal to each other.
In the given figure (5x + 82)° and (11x + 58)° are vertically opposite angles.
(5x + 82)° = (11x + 58)°
5x + 82 = 11 x + 58
82- 58 = 11x - 5x
24 = 6x
x = 24 /6 = 4
Then (5x+82) = (5(4) +82)= 102
(5x + 82)° and z° both are angles on same line therefore their sum will be 180°
(5x+82) +z =180
102+z=180
z= 180-102 = 78
Therefore, the value x= 4 and the angle z = 78°.
