In a proportional relationship, where k=1, what does y equal when x=5?
A. 5
B. 1/5
C. 0.5
D. 0.2
Answer:
5
Step-by-step explanation:
The question says a proportional relationship, of not stated otherwise, this means a directly proportional relationship, where,
y=kx
Now if, k=1, substituting in the equation would give,
y=x,
Therefore, whatever the value of x is, so is that the value of y,
thus, if x=5,
y=5

If a ballpoint pens sell for 3 for 65 cents how many pens may be brought for $9.75?
PLZ HELP THIS ASSIGNMENT IS DUE IN 2 HOURS I WILL GIVE BRAINLIEST!!
Answer:
About 45 pens would be bought
GIVEN,
3 pens can be bought for 65 cents
☞TO FIND
The number of pens that can be bought for $9.75
ANSWER
$9.75 = 975 cents
Therefore the number of pens that can be bought for $9.75 is,
[tex] \frac{975}{65} \times 3 \\ = 15 \times 3 \\ = 45[/tex]
So 45 pens can be bought

Which value of x will make the inequality true?
12 > x - 7
a. x 19
d. x > 5
Answer:
Step-by-step explanation:
I am going to solve solve your inequality step-by-step.
12>x−7
Step 1: Flip the equation.
x−7<12
Step 2: Add 7 to both sides.
x−7+7<12+7
Which gives the answer
x<19
he graph below represents the price of sending video messages using the services of a phone company. What is the constant of proportionality? A graph is shown. The values on the x axis are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10. The values on the y axis are 0, 24, 48, 72, 96, 120, 144, 168, 192, 216, 240. Points are shown on ordered pairs 0, 0 and 2, 48 and 4, 96 and 6, 144 and 8, 192. These points are connected by a line. The label on the x axis is Video Messages Sent. The label on the y axis is Price in cents. 12 24 46 48
Answer:
24.
Step-by-step explanation:
Basically constant of proportionality is a ratio.
We take two points, we'll take the order pair (2,48)
It will always be y/x so y is 48 and x is 2
48/2 - now we simplify
answer: 24

\sqrt{53+20\sqrt{7}} can be written in the form a+b\sqrt{c}, where a, b, and c are integers and c has no factors which is a perfect square of any positive integer other than 1. Find a+b+c.
=====================================================
Explanation:
Since the range of [tex]y = \sqrt{x}[/tex] is [tex]y \ge 0[/tex], this means that [tex]\sqrt{53+20\sqrt{7}}[/tex] cannot be negative.
-----------------------------------
Let's set the given nested radical expression equal to the form a+b*sqrt(c), and then square both sides to see what happens
[tex]\sqrt{53+20\sqrt{7}} = a+b\sqrt{c}\\\\\left(\sqrt{53+20\sqrt{7}}\right)^2 = \left(a+b\sqrt{c}\right)^2\\\\53+20\sqrt{7} = a^2+2ab\sqrt{c}+b^2c\\\\53+20\sqrt{7} = (a^2+b^2c)+2ab\sqrt{c}\\\\[/tex]
Equating the corresponding parts shows that
[tex]53=a^2+b^2c \text{ and } 20\sqrt{7} = 2ab\sqrt{c}\\\\[/tex]
Therefore c = 7 must be the case to allow the radicands to match up.
-----------------------------------
Since c = 7, we can update the first equation like so
[tex]53=a^2+b^2c\\\\53=a^2+b^2*7\\\\53=a^2+7b^2\\\\[/tex]
We'll come back to this later.
-----------------------------------
Focus on [tex]20 = 2ab\sqrt{7}[/tex]
Note how 20 and 2ab are coefficients outside the root. So 20 = 2ab leads to ab = 10.
Here are all the ways to multiply to 10 where a,b are integers
1*10 = 10-1*(-10) = 102*5 = 10-2*(-5) = 10So we could have these possibilities.
a = 1, b = 10a = 10, b = 1a = -10, b = -1a = -1, b = -10a = 2, b = 5a = 5, b = 2a = -5, b = -2a = -2, b = -5If you try all of those a,b combinations with [tex]53 = a^2 + 7b^2[/tex], then you should find that a = 5 and b = 2 works. I'm skipping a bunch of steps here. All you basically do is plug and chug.
Due to symmetry, we could have a = -5 and b = -2 as another solution to [tex]53 = a^2 + 7b^2[/tex]. However, if a < 0 and b < 0, then [tex]a+b\sqrt{c}[/tex] would be negative which contradicts the fact that [tex]\sqrt{53+20\sqrt{7}}[/tex] is positive. So we'll ignore any case where a,b are negative.
Therefore, the only combination that works is a = 5 and b = 2
-----------------------------------
Overall, we found that
a = 5b = 2c = 7And therefore,
[tex]\sqrt{53+20\sqrt{7}} = a+b\sqrt{c}\\\\\sqrt{53+20\sqrt{7}} = 5+2\sqrt{7}\\\\[/tex]
You can confirm this with your calculator by taking advantage of the idea "If x = y, then x-y = 0". In other words, if you subtract the left and right sides, you should get 0 as a result (the order of subtraction doesn't matter in this case). Don't forget to use parenthesis correctly, or you may not get 0. It might help to think of it as the form (x) - (y) = 0.
After we confirmed we have the correct a,b,c values, we simply add them up to get a+b+c = 5+2+7 = 14.
