Does the equation y = 4.2x represent a proportional relationship? Choose the correct response.
A. Yes. The constant of proportionality is 4.2.
B. Yes. The equation is linear.
C. No. The equation is linear.
D. No. There is a rate of change of 4.2.
Answers
Answer:
A .The constant of proportionality is 4.2
Step-by-step explanation:
The reason its a is because the rate of increase is always going to be be multiplied by 4.2 to stay increasing on a graph. So the constant change is always going to have to do something with 4.2

show that the (5,5),(5,0),and (0,0) are the vertices of an isosceles triangle.
Answers
An isosceles triangle has 2 sides that are equal.
I plotted these points. See attached screenshot.
The first side's distance is 5. You can just count those units along the x axis. (0,0) and (5,0) share the same y coordinate, so the difference in x coordinates is 5-0 = 5.
The next sides's distance is also 5. You can count that distance on the coordinate plane. (5,5) and (5,0) share the same x coordinate, so the difference in y coordinates is 5-0 = 5.
These two sides make a right triangle and are equal length. This is an isosceles right triangle.

The length of the wing on the model:
9 m * 1/30 = 900 cm * 1/30 = 30 cmb)
The area of the tail section of the plane:
80 cm² : (1/30)² = 80 cm² * 900 = 72000 cm² = 72000 * (1/100)² m² = 7.2 m²Answer:
The real plane's tail section is 2400 cm^2
Step-by-step explanation:
Well since the model is 1/30 of the real planes size
By multiplying the area of the tail section by 30 we should get the area of the real tail section in the plane
80*30= 2400 cm^2
The real plane's tail section is 2400 cm^2

Answer:
2x+5, 4x+11-2x-6 and 2x-x+3+x-3+5
Step-by-step explanation:
those three answers add up to 2x+5
Answer:
Option (A), (D), (F)
Step-by-step explanation:
Option (A) = 2x + 5
Option (D) = 4x + 11 - 2x - 6
Option (F) = 2x - x + 3 + x - 3 + 5
Now let’s Prove this statement.
(A) = 2x + 5
= 2x + 5
(D) = 4x + 11 - 2x - 6
= 4x - 2x + 11 - 6
= 2x + 5
(F) = 2x - x + 3 + x - 3 + 5
= 2x - x + x + 3 - 3 + 5
= x + x + 5
= 2x + 5
As we can see that all the 3 equations give the same result as 2x + 5
Hence we can prove that Option (A), (D), (F) are all equal.

Sheldon needs to buy 8 gallons of ice cream,
Prices of small size Price of large size
Cold farms $2.50 for 1 pint $4.50 for 1 quart.
Sweet dreams $4.25 for 1 quart $9.50 for one gallon.
Which size and brand of ice cream is the best deal?
Answers
Answer:
The larger size container and the Cold farms is the better deal for Sheldon.
Step-by-step explanation:
Given:
1 gallon = 8 pints
\(2.50 \times 8 =20\)
Multiply the gallons to 20
8 × 20 = 160
Then, the large size is 18.
4.50 ×4 =18 (1 Gallon= 4 quartz)
Therefore, the larger size container and the Cold farms is the better deal for Sheldon.
Answer:
Sweet Dreams Large Size (aka 9.50 for one gallon)
Step-by-step explanation:
8 gallons = 32 quarts = 64 pints
Cold farms pint
2.50 x 64 = $160
Cold farms quart
4.50 x 32 = $144
Sweet dreams quart
4.25 x 32 = $136
Sweet dreams gallons
9.50 x 8 = $76
$76 dollars is the least out of them all, so that is the answer.

a. PossibilitiesAs the tree diagram shows, the number of possible meals is ...
(possible meats)×(possible fruits)×(possible desserts)
= 3×2×2 = 12
There are 12 possible lunch options.
b. CookiesHalf the possible dessert choices have no cookie. That is the probability that a lunch will have no cookie:
P(no cookie) = 1/2
