What is the equation of the graphed line in slope intercept form?
(Graph is in the picture)
Answer:
y = 3x + 4
Step-by-step explanation:
y = mx + c where m is the slope and c is the y intercept.
Slope = [tex]\frac{rise}{run}[/tex]
Slope (taken from points (0, 4) and (1, 7)) = [tex]\frac{7-4}{1-0}[/tex]
= 3
y-intercept = 4
Equation: y = 3x + 4
Find the equation of the line in slope intercept form that is perpendicular to the line y= 2x -3 and that contains the point (1,-2)
Answer:
[tex]y=-\frac{1}{2} x-\frac{3}{2}[/tex]

find the value of this expression if x= -7
x^2+5/x+1
Answer:
-9
Step-by-step explanation:
Replace x with -7 in the expression:
x^2 + 5 / x + 1
-7^2 + 5 / -7 + 1
49 + 5 / -6
54/-6
simplify the fraction
9/-1 = -9

Write the point-slope form of the equation of the line through the given points.
3) through: (4,5) and (0,2)
Answer:
y - 5 = 3/4 (x - 4) so A
Step-by-step explanation:
It's would be A because the original equation is Y - Y1 = m (X - X1)
Since a coordinate is (x, y) the Y1 = 5 and the X1 = 4
If you plug those in the equation, it will give you y - 5 = m(x - 4)
Now, to figure out the slope, you have to know how you get can to the points (4, 5) from (0, 2). Slope is change in y / change in x. so to get from 0 to 4 for x, you add 4, and 2 to 5 for y, you add 3. Meaning the slope is 3/4. The m in the equation is the slope, so if you plugin the slope, the equation would be
y - 5 = 3/4 (x - 4)

What is the range of the function
f(x) = = 3x + 2 in the domain -2
Answer:
The range is:
{-4, 1, 2, 5, 8}
Step-by-step explanation:
Given the function
[tex]f(x)=3x+2[/tex]
We know that the domain of a function is the set of input or argument values for which the function is real and defined.As the domain interval -2 ≤ x ≤ 2
i.e. the values in the domain = {-2, -1, 0, 1, 2}
We also know that the range of a function is the set of values of the dependent variable for which a function is defined.As the domain interval -2 ≤ x ≤ 2
Putting all the x-values in the domain interval in the function
so
putting x=-2 in the function
[tex]f(x)=3x+2[/tex]
[tex]f(-2)=3(-2)+2=-6+2=-4[/tex]
putting x=-1 in the function
[tex]f(x)=3x+2[/tex]
[tex]f(-1)=3(-1)+2=-3+2=1[/tex]
putting x=0 in the function
[tex]f(x)=3x+2[/tex]
[tex]f(0)=3(0)+2=0+2=2[/tex]
putting x=1 in the function
[tex]f(x)=3x+2[/tex]
[tex]f(1)=3(1)+2=3+2=5[/tex]
putting x=2 in the function
[tex]f(x)=3x+2[/tex]
[tex]f(2)=3(2)+2=6+2=8[/tex]
Thus, when we put the domain values, the corresponding range values are:
x y
-2 -4
-1 1
0 2
1 5
2 8
Therefore, the range is:
{-4, 1, 2, 5, 8}

4.8x - 4.6 + 3.9x
Answer:
8.7x - 4.6
Step-by-step explanation:
4.8x - 4.6 + 3.9x
Group like terms
4.8x + 3.9x - 4.6
Add similar elements: 4.8x + 3.9x = 8.7x
Then you get your answer:

19. PLEASE HELPP !!Mel cleans houses.
She earns $7.50 every hour that she dusts.
She earns $10.00 every hour that she scrubs floors.
She scrubbed floors for 1 42 hours and dusted for 2 hours.
How much money did Mel earn?
PLEASE HELP !!
Answer:
1435.00
Step-by-step explanation:
dusted 2 hours. 15.00
Scrubbed floors 142 hours= 1420.00
Answer:
$30
Step-by-step explanation:
10$ x 1.5 (hours) = 15$ (the reason i did 1.5 is because she scrubbed for 1 and a half hours)
$7.50 x 2 (hours) = $15
$ 15 + $15 = 30
she earned $30 dollars

Answer:
B
Step-by-step explanation:
A line contains two distinct points, C and D. Select each correct statement,
Points C and D determine one unique line,
There are infinitely many points between points C and D.
The distance from C to D is equal to the distance from D to C.
O Any line segment that contains point C must also contain point D.
Answer:
We have a line that passes through points C and D.
a) Points C and D determine one unique line
This is true, there is only one line that passes through a given pair of points, then we can call this line as "Line CD".
b) There are infinitely many points between points C and D.
This is also true, if we define the points with real numbers in R^2, we will have a dense set, which means that between C and D we can find infinite points.
c) The distance from C to D is equal to the distance from D to C.
Also true, the distance between two points C = (cx, cy) and D = (dx, dy) is defined as:
D = √( (cx - dx)^2 + (cy - dy)^2)
And because we have squares, this will be exactly the same as:
D = √( (dx - cx)^2 + (dy - cy)^2)
Then the distance from C to D, is exactly the same as the distanco from D to C.
d) Any line segment that contains point C must also contain point D.
This is false, we can define infinite segments where the endpoint is C, and does not pass through point D (some examples are given in the image below) So this is the only false option.

Answer:
John's and Amber's wages are proportional to time. John's unit rate it $9 per hour. Amber's unit rate is $8 per hour
Step-by-step explanation:
The table(johns) shows this because he earns $9 more for every extra hour he works. this makes the unit rate $9 an hour.
The graph(ambers) shows that her pay increases at a steady rate, hitting a multiple of 8 every hour. This makes the unit rate $8 an hour.

Answer:
80 mStep-by-step explanation:
The described points form two right triangles which share same horizontal leg a.
The bottom triangle has 60 m vertical length and 60° opposite angle.
The triangle on the top has unknown (x) vertical length and 30° opposite angle.
We are looking for the distance x + 60 m
On the top triangle we have:
tan 30° = x/a ⇒ a = tan 30° / xOn the bottom triangle we have:
tan 60° = 60/a ⇒ a = tan 60° / 60Comparing we get:
tan 30° / x = tan 60° / 60 x = 60 tan 30° / tan 60°x = 20 mSo the distance is:
60 m + 20 m = 80 mTwo planes travel at a constant speed. Plane A travels 2,700 miles in 5 hours. Plane B travels 3,815 miles in 7 hours. Which plane is faster?
