Britney is passionate about movies and dreams of going to film school. Her goal for the next
year is to watch every movie that won the Academy Award for Best Picture. She's already
seen some of them and now plans to watch one per week until she's seen them all. After
following her plan for 2 weeks, Britney has seen 15 of the Best Picture winners. After 7
weeks, she has seen 20 of them.
In this relationship, x represents how long (in weeks) Britney has followed her plan, and y
represents the number of Best Picture winners she has watched.
Graph two points for this relationship and the line passing through them.

y = 9x + 14
y = 4x + 49
Answers
Answer:
x = 7; y = 77
Step-by-step explanation:
y = 9x + 14
y = 4x + 49
Since both equations are solved for y, set the two right sides equal and solve for x.
9x + 14 = 4x + 49
5x = 35
x = 7
Sow substitute 7 for x in the first equation and solve for y.
y = 9x + 14
y = 9(7) + 14
y = 63 + 14
y = 77
Answer: x = 7; y = 77
Answer:
x=7 y=77
Step-by-step explanation:
Subtract 4x from 9x you get 5x
subtract 14 from 49 you get 35
5x=35
9*7=63+14=77
4*7=28+49=77

Calculate the area
Answers
Answer:
140 feet squared
Step-by-step explanation:
Let's do this step by step. First, let's find the area of the rectangle, which is 8 times 10. It equals 80. Next, do the trangle. 6 times 10 is 60. So, 60 plus 80 equals 140.
Answer:
area of rectangle =L*B
8*10=80ft^2
area of triangle=1/2b*h
h is 8 ft
1/2*6*8
3*8
24ft^2
total area is 80+24
104ft^2
nearest tenth = 100 ft^2
Compare the graph of y = 4x and y = 4x + 1.
how are they the same how are they different
Answers
Answer:
Step-by-step explanation:
Notice that the difference is in the y-intercept. The first equation has a y-intercept of 0 since y = 4x + 0, the second has a y-intercept of 1 since
y = 4x + 1. In other words, the graph is translated up 1 unit to cross at (0,1) instead of (0,0)

What is an equation of the line that passes through the point ( − 1 , − 3 ) and is perpendicular to the line x − 2 y = 14? pls answer will mark you as brainiest
Answers
Answer:
y = -2x - 5
Step-by-step explanation:
First rewrite the second equation into y = mx + b format:
x - 2y = 14
2y = x - 14
y = x/2 - 14/2 (Divide both sides by 2)
y = 1/2x - 7
A line perpendicular to another has the negative reciprocal slope
So the slope of our first equation is -2. (Flip 1/2 = 2, then take the opposite)
Plug in the points (-1, -3) for the x and y coordinates.
x (x coordinate) = -1
y (y coordinate) = -3
slope (m) = -2
-3 = -1(-2) + b
-3 = 2 + b
-3 - 2 = b
b = -5
The equation of the line is y = -2x - 5. Hope this helps! :)
Answer:
y = -2x - 5 or 2x + y = -5
Step-by-step explanation:
Let's find the slope of the given line.
-2y = -x + 14
y = 1/2(x) -7
m = 1/2
The slope of a line perpendicular is the negative reciprocal of 1/2, which is -2
Now use the point-slope form of a line
y + 3 = -2(x + 1)
y + 3 = -2x - 2
y = -2x - 5 or 2x + y = -5
find the value of x?
Answers
Answer:
135
Step-by-step explanation:
Hello There!
Remember the exterior angle of a triangle rule:
An exterior angle of a triangle is equal to the sum of its opposite interior angles
so x = the sum of its opposite interior angles (58 and 77)
58 + 77=135
so x = 135
Answer: x=135°
Step-by-step explanation:
Angles in a triangle always add up to 180° so to find the corner of the missing side next to x you need to do 58+77=135 then do 180-135=45°
So then, now we have the angle inside the triangle, we can now work out what x is.
Angles on a straight line always add up to 180° so you do 180-45=135° so x=135°.
Hope this helps :)
Which shows the factored form of x2 – 12x – 45?
Answers
Answer:
(x - 15) ( x + 3)
Step-by-step explanation:
x² - 12x - 45
= x² - (15 - 3)x - 45
= x² - 15x + 3x - 45
= x(x - 15) + 3(x - 15)
= (x - 15) ( x + 3)

Find x and y with ray theorem
Answers
Answer:
x = 2
y = 5
Step-by-step explanation:
We can say:
7 corresponds to y
(3 + 7.5) corresponds to 7.5
Plus, we can write a ratio
[tex] \frac{7}{y} = \frac{3 + 7.5}{7.5} [/tex]
[tex] \frac{7}{y} = \frac{10.5}{7.5} [/tex]
Cross multiplying, we can solve for "y",
[tex] \frac{7}{y} = \frac{10.5}{7.5} [/tex]
[tex] \frac{7}{y} = 7 \times 7.5[/tex]
y = 5
Again, using similarly, we can say:
(x + 5) corresponds to 5
(3 + 7.5 = 10.5) corresponds to 7.5
We can write a ratio:
[tex] \frac{x + 5}{5} = \frac{10.5}{7.5} [/tex]
Cross multiplying and with the help of a but algebra, we can solve for "x", shown below:
7.5( x + 5) = 5 x 10.5
7.5x + 37.5 = 52.5
7.5x = 15
x = 2
