Answer:
-2
Step-by-step explanation:
You can see that when x goes up by 1, y goes down by 2. This means the rate of change is -2
Answer:
The rate of change is -2
Step-by-step explanation:
Take any two points from the graph. (0,-4) and (-2,0). Plug them into the equation y2-y1/x2-x1. In this case the equation would be 0--4/-2-0. Simplify this and get 0+4/-2-0. Simplify again and get 4/-2 which is -2
Therefore the rate of change is -2
Hope this helps

Are these triangles similar? Why?
A. Yes, SSS~ Postulate
B. Yes, SAS~ Postulate
C. Yes, AA~ Postulate
D. No, they are not similar.
Answer:
Step-by-step explanation:
<Q is common to both triangles.
130 / 40 = 3.25
Call DQ = x
40/130 = x / (x + 72) Cross multiply
40*(x + 72) = 130*x
40x + 2880 = 130x Subtract 40 x from both sides
2880 = 90 x Divide by 90
x = 32
(72 + 32)/32 = 104/32 = 3,25
The ratios are the same.
Therefore the triangles are similar by SAS

An arithmetic sequence has a 2nd term equal to 3 and 10th term equal to -13.
Find the term of the sequence that has value -93?
Answer:
n = 50
Step-by-step explanation:
Let a be the first term and d be the common difference.
An arithmetic sequence has a 2nd term equal to 3 and 10th term equal to -13.
[tex]a_n=a+(n-1)d[/tex]
According to the given condition,
[tex]a_2=3\\\\a_{10}=-13[/tex]
or
[tex]a+(2-1)d=3\\\\a+d=3\ ...(1)\\\\a+(10-1)d=-13\\\\a+9d=-13\ ...(2)[/tex]
Subtract equation (1) from (2).
a+9d-(a+d) = -13-3
8d = -16
d = -2
Put the value of d in equation (1).
a+(-2) = 3
a = 3+2
a = 5
Now,
[tex]a+(n-1)d = -93\\\\5+(n-1)(-2)=-93\\\\5-2n+2=-93\\\\7+93=2n\\\\2n=100\\\\n=50[/tex]
So, 50th term has the value of -93.

A taxi company charges passengers $1.75 for a ride, no matter how long the ride is, and an additional $0.40 for each mile traveled. The rule c = 0.40m + 1.75 describes the relationship between the number of miles m and the total cost of the ride c.
a. What is the charge for a 1-mile ride?
b. What is the charge for a 2.7-mile ride?
A. $2.15; $2.83
B. $0.40; $5.13
C. $0.40; $1.08
D. $1.75; $2.15
Answer:
A. $2.15; $2.83
Step-by-step explanation:
2.83
c = 0.4. * 2.7 + 1.75
=> c = 2.83
4(2.7)+1.75
1.08+1.75=2.83
$2.83 is correct.
c=0.40(2.7)+1.75
c=1.08+1.75
c=2.83
Answer:
2.83 dollars
Step-by-step explanation:
Fixed charges made by the taxi company for a ride =
Additional charge for each mile travelled =
Hence equation for cost is given by
where m is thenumber of miles travelled.
To find out the charge for a 2.7 mile ride substitute m = 2.7
Total cost for 2.7 mile ride is 2.83 dollars

The perimeter of the triangular park shown on the right is 11x - 7. What is the missing length?
Answer:
6x-4
Step-by-step explanation:
the perimeter is the distance around the shape, we get this by adding all the sides, call the missing side y and set up an equation for the perimeter
11x-7 = 4x+2 + x-5 + y
solve for y
11x-7 = 5x -3 + y
11x-4 = 5x + y
6x-4 = y

Given the equation of a line: y = (2/3)x + 1. Select the equation of the line PARALLEL to this line
Answer:
y = (2/3)x + K, where K is any number except 1
Step-by-step explanation:
In the slope-intercept form of the linear equation, y = mx +b, the 'm' is for the slope, m = 2/3.
Any line that also has a slope of 2/3 will be parallel.
y = (2/3)x - 10 will be parallel
y = (2/3)x + 12 will be parallel
y = (2/3)x - (1/2) will be parallel
y = (2/3)x + 5,391 will be parallel
Maybe this is a multiple choice question?
Because there is not really just one unique answer to the question as you have presented it.

Help I’m confused big points to who can solve this
Answer:
n = 2
Step-by-step explanation:
Given nx + y = 4, if we rearrange in slope-intercept form: y = -nx + 4
This means that the y-intercept is 4. Point "A" is the y-intercept, which would make OA = 4, and OB = 1/2(4) = 2.
We can now solve for n. The slope here is "-n", also represented by rise/run or OA/-OB = 4/-2 = -2.
-n = -2,
n = 2
