Answer: C) [-1,-3,-7,-19]
Step-by-step explanation:
Range = {-2(-2) - 5, -2(-1) - 5, -2(1) - 5, -2(2) - 5} = {4 - 5, 2 - 5, -2 - 5, -4 - 5} = (-1, -3, -7, -9}
Answer:
-2(-2)-5= -1 -2(-1)-5=-3 -2(1)-5=-7 -2(2)-5=-9... A. {-1, -3, 7, 9}
Step-by-step explanation:
By substituting each value of the domain of x in the function and solving it we will get the range of the function for respective domain
The given function is :
f(x) = -2x - 5
For x = -2 , f(x) is:
f(-2) = (-2*-2) - 5 = 4 - 5 = -1
For x = -1, f(x) is :
f(-1) = (-2*-1) - 5 = 2 - 5 = -3
For x = 1 , f(x) is
f(1) = (-2*1) - 5 = -2 -5 = -7
For x = 2, f(x) is
f(2) = (-2*2) - 5 = -4 -5 = -9
The range is -1 , -3 , -7 , -9

Here is a list of numbers.
32 29 30 37 34
34 33 31
Tanya thinks that to work out the median, she simply needs to find
the middle number. So she says that “37" is the median for this list of numbers.
Tanya's answer is not correct.
a) Describe what is wrong with her method.
b) Work out the median of the numbers in the list.
Step-by-step explanation:
32 29 30 37 34 34 33 31
a) Describe what is wrong with her method.
There two likely reasons why her answer is not correct;
- She did not arrange the numbers in order.
- The middle position belongs to two numbers, instead of finding the average she picked only one
b) Work out the median of the numbers in the list.
Arranging the numbers in ascending order;
29, 30, 31, 32, 33, 34, 34, 37
32 and 33 are both in the middle. The average of both numbers is the median
Median = (32 + 33) / 2 = 65 / 2 = 32.5

2(3w+w) = 40
2*4w = 40
8w =40
w = 5
l = 3*5 = 15

A membership to a movie night club costs $10 plus $2 per movie. Write the equation in slope intercept form to represent the situation
The equation in slope-intercept form is y = 2x + 10.
Option A is the correct answer.
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
Cost of membership = $10
Cost per movie = $2
The total cost for x movie.
= 10 + 2x
This can be written as,
y = 2x + 10
This is a slope-intercept form.
Where 2 is the slope.
Thus,
The equation is y = 2x + 10.

A car dealership buys a car for $12,500. They sell the car for $15,750. What is the percent markup?
Answer: 26%
Step-by-step explanation:
The formula to calculate the percentage markup is given as:
= Selling price - Cost / Cost price × 100
where selling price = $15750
Cost price = $12500
Percentage markup = ($15750 - $12500) / $12500 × 100
= $3250/$12500 × 100
= 26%
Answer: 26
Step-by-step explanation:
12,500 - 15,750= 3250
solve by substitution y - 3x = 2, x - 2y = -6
y=2+3x
putting value on second equation we get..
x-2(2+3x)=-6
x-4+6x=-6
7x=-2
×=-2/7
& y=2+3(2/7)
y=2+0.87
y=2.87..Ans..
Answer:
x= 2/5
y= 3.2
Step-by-step explanation:
y-3x=2
y=3x+2
replace y with 3x+2 in second equation;
x-2(3x+2)= -6
x- (6x+4)= -6
x-6x-4= -6
-5x-4+4=-6+4
-5x= -2
x= 2/5
y=3x+2
y=(3×2/5) +2
y= 3.2

Noticed how it forms a supplementary angle.
A supplmentary angle is basically two angles that added up to 180 degrees.
So we have:
64 + x = 180
Then we solve for "x", so "x" = 116.
Hope that makes sense :)

Write the equation of the line in slope-intercept form that goes through the points: (0, 5) and (4, 5)
Answer:
Step-by-step explanation:
The equation of a line written in slope-intercept form should be written as : y = mx + b
where m is the slope and b is the y-intercept.
We can find the slope, m, using the 2 points given:
(y2 - y1) / (x2 - x1) = (-12 -6) / (5- -4)
m= -18/9
m = -2
Then we can use this slope and one of the two points to find the intercept. Either point is fine but let's use (-4 , 6):
y = -2x + b
6 = -2 * -4 + b
6 = 8 + b
6-8 = 8 + b -8
-2 = b
The final equation of the line is: y = -2x -2
If the base angles of a triangle are congruent, use the Law of Sines to show the triangle is isosceles.
Answer:
The Isosceles Triangle Theorem States that if a triangle contains 2 congruent sides, then the angles opposite those sides are congruent. This theorem can be proved using the Law of Sines: The Law of Sines states that: asinA=bsinB=csinC If a=c, making △ABC an isosceles triangle, then asinA=asinC!

can someone explain to me how you figure out if a triangle is obtuse, acute or a right angle? i will give 20 points
Answer:
Right angle is 90 degrees, belowe 90 degrees is acute, and above 90 degrees is obtuse
Step-by-step explanation:
Right angle = 90degrees
Acute angle = <90degrees
Obtuse angle = >90degrees
Answer:
To figure out if a triangle is obtuse, There would be one angle that is over 90 degrees. If it is an acute triangle, all of the angles would be smaller than 90 degrees. If it is a right triangle, there would be one angle that is 90 degrees and the other 2 angles would be acute.

the length of a rectangle is 6 inches less than 4 times the width of the rectangle , write an expression to find the perimeter of the rectangle.
Answer:
x + (4x-6) • 2
Step-by-step explanation:
First, let's start by calling the width of the rectangle x
Because the length is 4 times the width minus 6, the equation for length will be 4x-6
The width and length together will be x + (4x-6)
You then have to times it by 2 to find the whole perimiter.
