Answer:

y=2.5x - Proportional  

y= x - 4 - Not Proportional  

Step-by-step explanation:

A linear function that is proportional is in the form y =kx (k is the constant of variation) and passes the origin.

The first equation given is in this form (2.5 is the constant) and it passes through the origin. It is proportional.

However, the second one is not proportional is it does not pass the orgin and it's not in y=kx form.

Hope this helps.

Answer:

okay for the buying vegetables problem. It wants us to write an equation in ST that gives us enough. The amount of pounds of cauliflower Capital C is our first very bold and broccoli bee is our second variable. So Capital C that says Karl Power costs $2 per pound so we can write to see and then broccoli is a dollar 25 per pound. So plus a dollar 25 times being is equal to the total cost that we spent. And the total we spent was $10. Okay, so there's our equation and standard corn. Thank you.

Answer:

Step-by-step explanation:

Actually, it would be (x+8,y-2) but the written part already has a + soo...

However, if you wish to complete problems like this in the future, pick one corner of the polygon and count how many places you mover right or left (x-axis. Right is going to be addition and left is going to be subtraction) and how many you move down or up (y-axis. up being addition and down being subtraction).

The statement that is true about the graph as it relates the unit rate is:

d. The unit rate is $22.50 per hour

Unit rate of a relationship between two variables, x and y, that are proportionally related can be found using k = y/x, where k is the unit rate.

Given that:

x = hours he worked

y = his total earnings

We are told that (4, 90) is a point on the graph.

Using the point, (4, 90), we can find the unit rate as shown below:

k = y/x = 90/4

k = 22.5

Therefore, the statement that is true about the graph as it relates the unit rate is:

d. The unit rate is $22.50 per hour

Answer:

B and E are the only correct answers.

Step-by-step explanation:

The top can's diameter is 2 inches, so the radius is 1. First find the area of the circular end, pi * r^2, 3.14 * 1^2 = 3.14

Then multiply by the height  3.14 * 5 = 15.7 cubic inches

The middle can's diameter is 5 inches so the radius is 2.5.

3.14 * 2.5^2 = 3.14 x 6.25 = 19.625

Multiply by the height 19.625 * 3 = 58.875 cubic inches

The bottom can's diameter is 6 inches, so the radius is 3. 3.14 * 9 = 28.26

Multiply by the height 28.26 * 2 = 56.52 cubic inches

15.7 + 58.875 + 56.52 = 131.095

B and E are the only correct answers.

Step-by-step explanation:

First, let’s flip the first term.

2^-x = 8^2-x

we can take ^3 out of the 8 to simplify

2^-x = 2^3(2-x)

-x = 3(2-x)

Now we solve for x.

x = 6

Step-by-step explanation:

1/36a^4b^10

Hope this is right!

The expression equivalent to the given expression is 1/36a⁴b¹⁰. Therefore, option C is the correct answer.

Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable.

The given expression is ((2a⁻³b⁴)²/(3a⁵b)⁻²)⁻¹.

Now, ((2²a⁻⁶b⁸)/(3⁻²a⁻¹⁰b⁻²))⁻¹

= (2⁻²a⁶b⁻⁸)/(3²a¹⁰b²)

= (a⁶)/(3²2²a¹⁰b²b⁸)

= 1/36a⁴b¹⁰

Therefore, option C is the correct answer.

Step-by-step explanation:

21^2+28^2=35^2

The third number of the Pythagorean triplet as c = 40.82.

Given is that 21 and 35 are two members of a Pythagorean triplet.

We can write the Pythagorean triplet as -

a² + b² = c²

c² = a² + b²

c² = (21 x 21) + (35 x 35)

c² = 441 + 1225

c² = 1666

c = √1666

c = 40.82

Therefore, the third number of the Pythagorean triplet as c = 40.82.

Answer:

x+y = 112 ........ (1)

x-y = 62............ (2)

from (1) and (2)

2x = 174

x = 174/2

x = 87

sub x = 87 in (1)

x+y = 112

87+y = 112

y = 112 - 87

y = 25

so the numbers are 87 and 25

The cost of 35 pounds of oolong tea is $84.

An equation is used to show the relationship between two or more variables or numbers.

Given that oolong tea sells for $2.40 per pound.

There are 35 pounds of oolong tea available. Hence:

Cost of 35 pounds of oolong tea = $2.40 per pound * 35 pound

Cost = $84

Hence, the cost of 35 pounds of oolong tea is $84.

Answer:

35 LB (THIS IS ACTUALLY CORRECT)

Step-by-step explanation:

First, you lay it down like this:

Since you're selling 35 pounds of oolong tea that sells for $2.40, you multiply both

2.4*35

=84

However, since you don't know how many pounds of black tea, you use x

Multiply like above

1.8*x

=1.8x

The total mixture is selling for $2.10

Total pounds: 35 + x (given above, or black + oolong tea

equation:

84 + 1.8x = 2.1(35+x)

84 + 1.8x = 73.5 + 2.1x (distributive property)

    - 1.8x             - 1.8x

84 + 0 = 73.5 + 0.3x

-73.5             -73.5

10.5 = 0.3x

3.5 = 0.1x

35 = x

Answer:

y=3x+1

Step-by-step explanation:

To figure out equations of tile patterns simply count the initial value and the rate of change, then convert it into (slope intercept form) which is

y = mx+b

In this case in figure 2 we see that there are 4 blocks, in figure 3 we see there are now 7 blocks.

7 - 4 = 3.

If we try again and see figure 3 has 7 blocks and figure 4 has 10 blocks we can do this to double check.

10 - 7 = 3. (This now verifies our rate of change to be 3)

We now see that the rate of change or slope (same thing) is 3 or put into the equation (3x).

Off this information we can also predict the original value of figure 1 (the figure we must calculate ourselves to create the equation).

Simply take figure 2 (4 blocks) and subtract by the rate of change which is (3 blocks) to get figure 1 which will be 1 block.

With all this information we can create the equation with the information we now have.

y = mx+b

y = what you are calculating for

m = 3

x = (the value you fill in when you are calculating for x) [we are not filling this in for this question so you will leave it as simply x]

b = 1        (the constant / y intercept / or simply put as the value we solved when calculating figure 1)

Final Result = [ y = 3x + 1]

Answer:

14%

Step-by-step explanation:

So if we have 4 Year 11 pupils out of a total of 29 pupils at a football club, the fraction for that would be 4/29, if we convert 4/29 into a decimal number we get 0.13793103448, so we round this number up to the nearest 1 decimal place, and that would be 0.14 which equals 14%. Hope this helps.
