What is a slope?
The slope or gradient of a line is a number that describes both the direction and the steepness of the line. It is denoted my letter 'm'
y = m x + c
m is the slope
Given data ,
Let the point be P ( x , y ) = P ( 0 , 7 )
Slope m of line = 1 / 6
The equation of line where the point P ( 0 , 7 ) and slope 1/6 is calculated by
y = m x + c
Substitute the values of x and y in the equation , we get
7 = ( 1/6 ) × 0 + c
So , c = 7
Therefore , the equation becomes y = ( 1 / 6 ) x + 7
Hence , the graph of the equation can be described

Which is the equation of the graphed line written in standard form?
A. y=x
B. x-1/2y=0
C. x-y=0
D. y=1/2x
Answer:
The standard for of this equation is x – y = 0
Firstly, options A and D are not in standard form, so they are not options.
To decided between B and C, we choose a point on the line and see if it works. For example, we'll use (2, 2).
x – y = 0
2 - 2 = 0
0 = 0
This is true for option C. Therefore, it is correct.
hope this helps

Which of the following exponential functions represents the graph below?
Answer:
C
Step-by-step explanation:
So you should be looking for the right function.
Remember that any number to the power of 0 is by definition 1.
3 * 1 = 3
In the graph you see point (0,3), so what you do is to check for each function if f(0)=3.
So if you substitute x= 0 the result should be 3.
3 * 1 = 3
The two functions that comply with that, are the ones in answers B or C.
In the graph you can also see point (1,6). So if you substitute x= 1 the result should be 6.
The only function that complies with that is in answer C.

Answer:
$997
Step-by-step explanation:
Base Salary: $150 (given)
Additional information on everything he sells: 14%
He sells $6050.00 last week, so then his commision would be 14% of the $6050.
x = 150 + ( 0.14 x 6050 )
OR
14/100 x 6050
would equal: $847
Total pay for last week would equal base salary and the additional pay.
$150 + $847
= $997
His total pay for last week would equal $997.

Answer:
17.7 and 4.09
Step-by-step explanation:
Using the sine ratio in both right triangles
(49)
sin43° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{a}{26}[/tex] ( multiply both sides by 26 )
26 × sin43° = a, thus
a ≈ 17.7 ( to 1 dec. place )
----------------------------------------
(50)
sin43° = [tex]\frac{a}{6}[/tex] ( multiply both sides by 6 )
6 × sin43° = a , thus
a ≈ 4.09 ( to 2 dec. places )

Consider the table showing the given, predicted, and residual values for a data set.
A 4-column table with 4 rows. The first column is labeled x with entries 1, 2, 3, 4. The second column is labeled given with entries negative 1.6, 2.2, 4.5, 6.1. The third column is labeled predicted value with entries negative 1.2, 1.5, 4.7, 6.7. The fourth column is labeled residual value with entries negative 0.4, 0.7, negative 0.2, negative 0.6.
Which point would be on the residual plot of the data?
Answer:
(4, -0.6)
Step-by-step explanation:
The table is:
x Given Predicted Residual value
1 -1.6 -1.2 0.4
2 2.2 1.5 0.7
3 4.5 4.7 -0.2
4 6.1 6.7 -0.6
The points on the residual plot must be the pairs (x, residual value). This is:
(1, 0.4)
(2, 0.7)
(3, -0.2)
(4, -0.6)
Thus, the correct choice is the last one: (4, -0.6)
The point that would be on the residual plot of the data is (4, -0.6). See the explanation below.
What is a residual plot?A residual plot is a graph in which the residuals are displayed on the vertical axis and the explanatory variables is displayed on the horizontal axis.
From the analysis of the table attached, we have the following points on the residual plot:
(1, 0.4)
(2, 0.7)
(3, -0.2)
(4, -0.6)
Point on the residual plot must include the point on x and a residual value, hence, the correct answer is (4, -0.6).

Answer:
x = 51
Step-by-step explanation:
2x + 4 + x + 23 = 180
3x + 27 = 180
3x = 153
x = 51
Answer:
Step-by-step explanation:
Because the lines are intersecting they are equal to 180. Therefore...
(x+23) + (2x+4) = 180
3x + 27 = 180
3x = 153
x = 51

What is the y-intercept of the equation 4x + 5y = 20?
(0,4)
(0,5)
(4,0)
(5,0)
Answer:
(0,4)
Step-by-step explanation:
4x+5y=20
5y=20-4x
y=4-4/5x
y-intercept means a point on the y-axis(x=0)
y=4-4/5x
y=4-4/5(0)
y=4
Therefore, y-intercept is at (0,4)
The length of a rectangle is 9 inches longer than the width. If the area is 205 square inches, find the
rectangle's dimensions. Round your answers to the nearest tenth of an inch.
Answer:
L=19.5in w=10.5in
Step-by-step explanation:
Draw a rectangle. If the length is 9 inches longer than its width, we can write the width as "w" and the length as the width + 9
Area is (width)(Length) = (width)(width+9)
W
----------
| |
| |
| | L = w+9
| |
| |
-----------
A = (w+3)(w)
A = w2 + 9w = 205.
(Problem states that area is 205 sq in)
Need to solve this quadratic equation
w2 + 9y - 205 = 0
Factor:
(w - 10.51) (w + 19.51) = 0
So
w - 10.51 = 0. or. w + 19.51 = 0
Solve these and get
w = 10.51. or. w = -19.51
Only one that makes sense in real life is the positive one.
So the dimensions are
Width = 10.51 inches
Length = 19.51 inches
