Thereisalinethatincludesthepoint(0, 19)andhasaslopeof 10/9 . What isitsequationin slope-intercept form?
Answer: y=(10/9)x+19
Step-by-step explanation:
The slope intercept form is y=mx+b, where m is the slope and b is the y-intercept (the value of y when x=0).
We are given the slope, m:
y=(10/9)x+b
To find b, enter the given point (0,19) and solve for b:
y=(10/9)x+b
19=(10/9)*(0)+b
b = 19
So we have y=(10/9)x+19

Find f ◦ g, g ◦ f, and g ◦ g.
f(x) = x + 2, g(x) = x - 5
Answer:
fg(x)=f(g(x)
=f(x-5)
But ;f(x)=x+2
f(x-5)=(x-5)+2
=x-5+2
fg =x-3
gf(x)=g(f(x))
=g(x+2)
But ;
g(x)=x-5
g(x+2)=(x+2)-5
=x+2-5
=x-3
g(g)=g(x-5)
g(x-5)=(x-5)-5
=x-5-5
=x-1

45°= Acute Angle
‘Cause It's less than 90°
Answer:
Step-by-step explanation:
It's an acute angle. Acute, in this case, means anything between 0 and 90 written 0<x<90. Notice that you are using < and not ≤. The endpoints are not included. They have their own names. 90 is a right angle. 0 is called a zero degree angle.

A rectangular table is measured to be 264 centimetres long and 1.55 metres wide.Convert the length of the rectangular table to metres. Write your answer as a decimal.
Answer:
2.64m
Step-by-step explanation:
A rectangular table is measured to be 264 centimetres long and 1.55 metres wide.Convert the length of the rectangular table to metres. Write your answer as a decimal.
100cm = 1m
so
264cm = 2.64m
Write the equation of the line in fully simplified slope-intercept form.
Answer:
you can write the equation of any line in the form of y = mx + b .
Step-by-step explanation:
Answer:
[tex]y = - \frac{1}{6} x + 2[/tex]
Step-by-step explanation:
Slope-intercept form
y= mx +c, where m is the slope and c is the y-intercept.
Let's first identify the coordinates of two points on the graph:
(-6, 3) and (6, 1)
[tex]\boxed{slope = \frac{y1 - y2}{x1 - x2} }[/tex]
Slope
[tex] = \frac{3 - 1}{ - 6 - 6} [/tex]
[tex] = \frac{2}{ - 12} [/tex]
[tex] = - \frac{1}{6} [/tex]
Substitute the value of the slope into m in the equation:
[tex]y = - \frac{1}{6} x + c[/tex]
To find the value of c, substitute a pair of coordinates into the equation.
When x= 6, y= 1,
[tex]1 = - \frac{1}{ 6} (6) + c[/tex]
1= -1 +c
c= 1 +1
c= 2
Thus, the equation of the line is y= -⅙x +2.
The y-intercept can also be derived from the graph as we can see that the line passes through the y- axis at (0, 2). This point can also be used to find the slope of the line too.

If y varies directly with x and y=12 when x=3, find y when x=1.
Answer:
y = 4
Step-by-step explanation:
y ∝ x
y = kx (k is constant)
when y = 12 and x = 3
y = kx
=> 12 = k*3
∴ k = 4
when x = 1 and k = 4
y = kx
= 4*1
= 4

Step-by-step explanation:
Distance formula: (see attached file) pythogorean rule
is the squared coordinates x added to squared coordinates of y
X- coordinates: -5 & -9
Y- coordinates: -5 & -2
Substitute into equation:
[tex]distance = \sqrt{ ( - 5- - 9)^{2} + ( - 5 - - 2)^{2} } = 5[/tex]
How do I factor an equation in the Ax^2+Bx+C form, if A= 2, B= 15, and C= -27. I tried using the x method but I don't think it's the right way.
Answer:
(2x - 3)(x + 9)
Step-by-step explanation:
A = 2
B = 15
C = -27
when we plug these numbers into the equation (Ax^2 + Bx + C) we get
2x^2 + 15x - 27
using the "X" method we have to multiply the A term and C term together
so -27 x 2 = -54
so we have to find factors of -54 that also add to the middle term, 15
- 3 and 18 add to 15 but also multiply to -54 so we can add these numbers into the X (refer to drawing)

A Web music store offers two versions of a popular song. The size of the standard version is 2.9 megabytes (MB). The size of the high-quality version is 4.6 MB. Yesterday, the high-quality version was downloaded three times as often as the standard version. The total size downloaded for the two versions was 4342 MB. How many downloads of the standard version were there?
Answer:
260 Downloads
Step-by-step explanation:
s = number of standard downloads
3s = number of high-quality downloads
2.9s + 4.6(3s) = 4342
2.9s + 13.8s = 4342
16.7s = 4342
s = 260
The standard version was downloaded 260 times and the high-quality version was downloaded 780 times.
What do I do with the “y = -f(x) +6” given to find the Domain and Range?
Answer:
Step-by-step explanation:
a.Changing f with -f does not change its domain, it just flips the image across the x axis. Adding 6 to the result, just shifts everything towards the positive y by 6 units. Domains stays the same, from -4 to +8. Range instead goes up, the lowest value is -2+6 = 4 and the highest value is 2+6 = 8.
So domain remains the same [-4; 8] and range goes to [4;8]
a. This time we're shifting everything on the horizontal axis, one unit to the left (the way to remember it is that f(x) has a minimum at x=4, while after the shift the new value happens at x=3) multiplying the value by 3 means that every value gets scaled up. It means the minimum becomes -2*3= -6 and the maximum happens at 2*3= 6. The shift brings the domain to [-5;7] and the range to [-6,6]

Three friends attended a game together.
The cost of one ticket was $50.
The cost of parking, p, was shared equally.
Write an expression to represent the dollar amount it cost each friend to attend the game?
Answer:
50+p/3
Step-by-step explanation:
Each friend has a 50 flat fee = 50
Parking is divided between 3 people so each person pays 1/3 of the parking fee
if p = price of parking 50 + p/3
The table above gives population and employment numbers for a hypothetical country. What is the unemployment rate in this country? Round your answer to the nearest whole percent if necessary
WHAT IS THE ANSWER HELP lol
Answer:B. 17%
A.83%
B.17%
C.20%
D.10%
The unemployment rate in this hypothetical country is equal to 17%.
How to calculate unmployment rate.First of all, we would determine the percentage of people that are employed and then subtract this percentage from the total percentage of 100%.
The table below gives the complete information about the population and employment numbers for a hypothetical country:
Total population = 1,000Total population over 16 years of age = 800Total labor force = 600Total employment = 500Mathematically, employment rate can be calculated by using this formula:
[tex]Employment\;rate = \frac{Employed}{Labor\;force} \times 100\\\\Employment\;rate =\frac{500}{600} \times 100\\\\[/tex]
Employment rate = 83.3 ≈ 83%.
For the unemployment rate, we have:
Unemployment rate = 100 - 83
Unemployment rate = 17%.

Certain drug is used to treat asthma in a clinical trial of the drug 24 of 282 treated subject experienced headaches based on the data from the manufacturer the accompany calculator display results from a test of the claim that less than 11%
Answer:
See below
Step-by-step explanation:
The test is one-tailed (left-tailed in this case) because you are trying to prove that the true proportion is less than the proposed proportion of 11%
The test statistic, z, is given to us as z=-1.34 when rounded to 2 decimal places.
The p-value, p, is given to us as p=0.0908 when rounded to 4 decimal places.
The null hypothesis is [tex]H_o:p<0.11[/tex] because the original claim was that the proportion was less than 11%.
Hope this helped! It's been a while since I've done Statistics, but I believe this is all correct.
