Answer:
x=33
y=134
z=46
Step-by-step explanation:
Lets solve for Z first. It is in a triangle with 2 angles already known: 84 and 50. Because the 3 angles in all triangles add to 180...
z+50+84=180
z=180-50-84
z=46
Angles z and y are supplementary, because they exist on the same line and are cut off by one line segment. This means that their angles add to 180.
180=y+z
we already know that z=46
180=y+46
y=180-46
y=134
Now we can use the same rule we used to find z, to find x.
x+y+13=180
we just found that y=134
x+134+13=180
x=180-134-13
x=33

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
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.

The number of cups of dog food a dog eats varies directly with the number of cups of eater it drinks. In a certain period, the dog eats 16 cups of dog food and drinks 6 cups of water. How many cups of dog food will a dog eat if it drank 15 cups of water?
I really need help
Answer:
40 cups of foodStep-by-step explanation:
Equation of direct variation:
y = kx, where k is the coefficient of variationWe have:
16 = 6kFind the value of k:
k = 16/6 = 8/3Now the equation is:
y = 8/3xWe have x = 15, find the value of y:
y = 8/3*15 = 8*5 = 40find the value of X in the triangle shown below

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.
Write this equation in slope intercept form.
What is the slope and y-intercept?
3y + 3x = 15
Answer: the slope is -1, and the y-intercept is 5.
Step-by-step explanation:
To find the slope and y-intercept, we change the equation to y = mx + b form, where m is the slope and b is the y-intercept.
3y + 3x = 15 (Minus 3x to both side)
3y = -3x + 15 (Divide 3 from the both side, to get in term of y)
y = - x + 5
Using y = mx + b form, in this case, the slope is -1, and the y-intercept is 5.

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
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
Today, the price of a new cellphone is $380. In 2010,
the price of a similar cellphone was $240. What is the
percent of change in the price of a cellphone from 2010
to today? Round your answer to the nearest hundredths
place.
The percent of change in the price of a cellphone from 2010
to today is 58.33%
The price of cellphone was $240 in 2010.
While the price of cellphone presently is $380.
The percent of change in the price of a cellphone from 2010 to today is:
Percent change in price = [(380 - 240)/240] * 100%
Percent change in price = 58.33%
Hence, The percent of change in the price of a cellphone from 2010
to today is 58.33%

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]

What type of angle is 45 degrees???
Answer:
Acute angle
Step-by-step explanation:
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.

0.5 x 30 = 15 and 0.5 x 20 = 10
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
