Step-by-step explanation:
Work out the differences between the terms of the sequence:
[tex]1 \underset{+2}{\longrightarrow} 3 \underset{+4}{\longrightarrow} 7 \underset{+6}{\longrightarrow} 13 \underset{+8}{\longrightarrow} 21[/tex]
The differences between terms increase by 2 each time.
Therefore, from inspection of the pattern, the next three terms in the sequence are:

If xx and y vary directly and y is 21 when x is 7, find y when x is 5
Answer:
y = 15
Step-by-step explanation:
We need to solve for k
y = x
21 = 7k Divide both sides by 7 to solve for k
3 = k
y = xk
y = 5(3)
y = 15
Answer: y = 15

. If Ashley pays $6, what was the original price?
Answer:
$8
Was the original price.
Step-by-step explanation:
100% - 25% = 75%
$6 ⇒ 75%
$A ⇒ 100%
A = $6* 100% / 75%
A = 8
Draw a right-angled isosceles triangle and write its measures.
Answer:
45 ∘,45 ∘ ,90 ∘
Step-by-step explanation:
Since, the angle is right angled isosceles triangle. One of the angles will be 90 ∘
. let the other two angles be x
Thus, sum of angles = 180
90+x+x=180
2x=90
x = 45 ∘
The measure of each angle is: 45 ∘ ,45 ∘ ,90 ∘

If x and y are in direct proportion and y is 80 when x is 10, find y when xx is 15.
Answer:
y = 120
Step-by-step explanation:
If x = y, they can be written as a fraction to show their proportionality as [tex]\frac{10}{80}[/tex]. This is equal to [tex]\frac{1}{8}[/tex], so when x = 1, y = 8. To find when y is equal to x when x = 15, just multiply y by 15. 15(8) = 120, so y = 120 when x = 15.
Answer:
120
Step-by-step explanation:
set up a proportion: 80/10=y/15
solve: 80*15=10y
1200=10y
y=120

The speed limit on an interstate highway is 65 miles per hour.
Which cars are driving at or below the speed limit?
Answer:
There are 5,280 feet in a mile.
There are 60 minutes in an hour.
As a quick check, does this answer look correct? If you were travelling 5 miles per hour slower, at a steady 60 mph, you would be driving 60 miles every 60 minutes, or a mile a minute. If you're driving 65 miles per hour, then, you ought to be going just over a mile a minute — specifically, 1 mile and 440 feet.
While it's common knowledge that an hour contains 60 minutes.
Step-by-step explanation:
If your car is traveling 65 miles per hour, then it is also going 343,200 feet (65 × 5,280 = 343,200) per hour. Then, you can divide the total feet per hour by 60, and you know that your car is traveling 5,720 feet per minute.

The table shows a proportional relationship between x and y.
x 12 18 30
y 4 6 10
Describe the graph of the proportional relationship, in words.
A line beginning at point (12, 4) and continuing through the point (10, 30).
A line beginning at point (12, 4) and continuing through the point (6, 18).
A line beginning at point (0, 0) and continuing through the point (30, 10).
A line beginning at point (0, 0) and continuing through the point (4, 12).
A line beginning at point (0,0) and continuing to (30,10)
A proportional relationship will always go through the origin so you can eliminate the first two. In the last one the second coordinate is (4,12) which is wrong because the x is 12 and the y is 4. So that is how you know the 3rd option is correct :)

Which is an equation of a direct proportion?
The correct answer is y = -2x.
Direct proportion can also be known as Direct variation. When the ratio of two quantities equals constant, we call it Direct Proportion. Direct Proportion is denoted by [tex]\alpha[/tex] .
Let us consider two quantities a and b, then the direct proportion between a and b can be expressed as,
a [tex]\alpha[/tex] b
=> [tex]a/b = k[/tex] ( where k is constant)
=> [tex]a = kb[/tex] [tex]--- >[/tex] 1
Substitute a=x and b=y in 1, and then we get
[tex]x = ky[/tex]
Therefore, the general form of an equation which satisfies direct proportion is x = ky.
[tex]y=1/2x-2, y=-2x+3,y=4/x[/tex] are not in the form of [tex]x = ky[/tex].
So, The equation of direct proportion is y = -2x.
