Part F Think about graphing the relationship between the length of the TV screen and the price. What do you predict the graph will look like?
Answer:
The ratios are not equivalent, so the relationship is not proportional. Therefore, the graph will not be a straight line passing through the origin.
Step-by-step explanation:
Since the ratios of the relationship between length of TV screen and price are not proportional, the graph would not be a proportional graph.
What is a Proportional Graph?A proportional graph is a straight line graph that passes through the origin (0, 0).
If a relationship has a proportional ratio, then the graph that represents the relationship would be a proportional graph.
Therefore, since the ratios of the relationship between length of TV screen and price are not proportional, the graph would not be a proportional graph.

Taxi ride expression
Answer:
Let’s just hail a taxi.
Step-by-step explanation:
An unknown polynomial is added to the expression -3x³ + 2x – 5 and the resulting sum is 4x³ + 7x² – 3. What is the unknown polynomial?
The first polynomial is:
-3x³ + 2x – 5
Then we add a polynomial p(x) and we get:
-3x³ + 2x – 5 + p(x) = 4x³ + 7x² – 3
We will find that p(x) = 7x³ + 7x² - 2x + 2
Now let's see how we got it:
Notice that the degree of the polynomial does not change, so p(x) is a polynomial of degree 3.
Then we can write:
p(x) = ax³ + bx² + cx + d
Then we have:
-3x³ + 2x – 5 + ( ax³ + bx² + cx + d) = 4x³ + 7x² – 3
(-3 + a)x³ + bx² + (2 + c)x + (-5 + d) = 4x³ + 7x² – 3
Notice that the above inequality should work for every value of x, so the terms with the same exponent must be equal between them:
(-3 + a)x³ = 4x³
bx² = 7x²
(2 + c)x = 0
(-5 + d) = – 3
Now we can remove the variables in all of these equations to get:
(-3 + a) = 4
b = 7
(2 + c) = 0
(-5 + d) = – 3
Now we can solve all of these and find the coefficients of our polynomial p(x).
-3 + a = 4
a = 4 + 3 = 7
a = 7
b = 7
2 + c = 0
c = -2
-5 + d = -3
d = -3 + 5 = 2
d = 2
Then we have:
p(x) = 7x³ + 7x² - 2x + 2

A pair of shoes that
originally cost $45 is
30% off. What is the
selling price?
Work Shown:
30% of 45 = 0.30*45 = 13.50
You save $13.50 and the sale price is 45 - 13.50 = 31.50 dollars
An alternative is to compute
0.70*45 = 31.50
This works because if you save 30%, then you have to pay the remaining 70%

how would I graph this correctly?
Answer:
You would shade the fourth quadrant (bottom right).
Step-by-step explanation:
Due to the domain and range sets, you're given the facts that x must be greater than or equal to 0, but y is less than or equal to zero. This gives you what quadrant the graph should be in. Since you're not given an equation to follow like y=ax+b, then I can not say that this will give you a line.

Suppose u and v are orthogonal vectors with ||u|| =5. ||u||= 1/2 ||v||, find ||u+v||.
Answer:
[tex]5\sqrt{5}[/tex]
Step-by-step explanation:
See attached image.
The vectors u and v are orthogonal, so the angle between them measures [tex]90^\circ[/tex]. [tex]||u||=5[/tex] and [tex]||u||=\frac{1}{2}||v|| \Rightarrow ||v||=10[/tex]

A shirt and pants have a combined cost of 78 dollars. The shirt costs 15 dollars less then the pants. How much does each item cost
Answer:
The shirt is $31.50 and the pants are $46.50
Step-by-step explanation:
Let x represent the cost of the pants.
If the shirt is 15 dollars less than the pants, its cost can be represented by x - 15.
Create an equation, and solve for x:
(x) + (x - 15) = 78
2x - 15 = 78
2x = 93
x = 46.5
So, the pants are $46.50.
Subtract 15 from this to find the cost of the shirt:
46.50 - 15
= 31.50
The shirt is $31.50 and the pants are $46.50
The sum of the angle measures of a quadrilateral is 360 degree . Write and solve an equation to find the value of x .
A quadrilateral with interior angles marked as x degrees, 150 degrees, 77 degrees, and 48 degrees.
The equation is
360= .
x=
Answer:
Step-by-step explanation:
The value of the angle x is 85°
The sum of angles of a quadrilateral = 360°
This means that given a quadrilateral with angles, A, B, C, D ;
(A + B + C + D) = 360°
Given the angles of a quadrilateral : (x°, 150°, 77°, 48°)
The value of x will be obtained thus :
(x + 150 + 77 + 48) = 360
150 + 77 + 48 + x = 360
275 + x = 360
x = 360 - 275
x = 85°
Hence, the value of x is 85°
