Write the equation of the line, in point-slope form. Identify (x1, y1) as the point (-2, 2). Use the box provided to submit all of your calculations and final answers.
Answer:
Slope: -1
Point-Slope Form: y - 2 = -1 (x - (-2))
Step-by-step explanation:
Answer: y-2=-1(x+2)
Step-by-step explanation: use whichever points you want I’m using (-2,2)
Find slope: y2-y1/x2-x1 so 2+2/-2-2 = 4/-4 = -1
Plug in these into y-y1= m(x-x1)
y-2= -1(x+2)

Keisha is reading a 310 page book at a rate of 23 pages per day.Use a point-slope equation to determine how many pages she will have left to read after reading the book for 10 days. She will still have [ ] pages left to read after 10 days.
Answer:
80 pages
Step-by-step explanation:
Point slope Equation is :
y = mx + c
In the above question
y = 310 pages
x = number of days = 10 days
m= 23 pages per day
c = ?? Unknown
c = y - mx
c = 310 - 23 × 10
c = 310 - 230
c = 80 pages
She will still have 80 pages left to read after 10 days

Here are two similar rectangles find the area of the largest one
Answer:
40.32 cm²
Step-by-step explanation:
The area of the small rectangle = 7 × 4 = 28 cm²
Given the ratio of the sides of similar rectangles = a : b , then
the ratio of the areas = a² : b²
Here ratio of sides = 4 : 4.8 = 1 : 1.2
ratio of areas = 1² : 1.2² = 1 : 1.44
Let x be the area of the larger rectangle then by proportion
[tex]\frac{1}{28}[/tex] = [tex]\frac{1.44}{x}[/tex] ( cross- multiply )
x = 40.32
Area of larger rectangle is 40.32 cm²

A traveler is walking on a moving walkway in an airport. The traveler must walk back on the walkway to get a bag he forgot. The traveler's ground speed is 1 fts against the walkway and 5 ft/s with the walkway. What is the traveler's speed off the walkway? What is the speed of the moving walkway? The traveler's speed off the walkway is ft/s.
Answer: here is your answer
Step-by-step explanation:
You can put this solution on YOUR website!
+t+ = traveler's speed in ft/sec
+w+ = walkway's speed in ft/sec
given:
+t+-+w+=+2+
+t+%2B+w+=+6+
-------------
Add the equations
+2t+=+8+
+t+=+4+
and
+t+%2B+w+=+6+
+4+%2B+w+=+6+
+w+=+2+
The traveler's speed off the walkway is 4 ft/sec
The speed of the moving walkway is 2 ft/sec

How many solutions are in the graph
A. One solution
B. Two solutions
C. No solutions
D. Infinitely many solutions
Answer:
Infinite Many Solutions
Step-by-step explanation:
If I am correct the two lines are overlapping each other in more than one place so that means there are infinitely many solutions. Also, there can be no " two solutions" for this type of equation. There can only be one solution, no solution, or infinitely many solutions.

Please do elimination method 2x-9y=-36
-14x+18y=-18
Answer:
The solution to the system of equations will be:
[tex]x=9,\:y=6[/tex]
Step-by-step explanation:
Given the system of equations
[tex]\begin{bmatrix}2x-9y=-36\\ -14x+18y=-18\end{bmatrix}[/tex]
Multiply 2x-9y=-36 by 7
[tex]14x-63y=-252[/tex]
so the system of equations becomes
[tex]\begin{bmatrix}14x-63y=-252\\ -14x+18y=-18\end{bmatrix}[/tex]
Adding both equations
[tex]-14x+18y=-18[/tex]
[tex]+[/tex]
[tex]\underline{14x-63y=-252}[/tex]
[tex]-45y=-270[/tex]
solve -45y = -270 for y
[tex]-45y=-270[/tex]
divide both sides by -45
[tex]\frac{-45y}{-45}=\frac{-270}{-45}[/tex]
Simplify
[tex]y=6[/tex]
For 14x-63y = -270 plug in y = 6
[tex]14x-63\cdot \:6=-252[/tex]
[tex]14x-378=-252[/tex]
Add 378 to both sides
[tex]14x-378+378=-252+378[/tex]
Simplify
[tex]14x=126[/tex]
Divide both sides by 14
[tex]\frac{14x}{14}=\frac{126}{14}[/tex]
Simplify
[tex]x=9[/tex]
Therefore, the solution to the system of equations will be:
[tex]x=9,\:y=6[/tex]

Step-by-step explanation:
Evaluate y = -4(5)* for x = 2
The value of the function at x = 2 is -100
Exponential equationThey are written in the form y = ab^x
Given the exponential function y = -4(5)^x
IF the value of x is 2, hence the expression becomes:
y = -4(5)^2
y = -4(25)
y = -100
Hence the value of the function at x = 2 is -100
