pls answer this....................................................................................................................................................................................................................................................................................................................................................................................is -5x+10 proportional and if it has a positive y intercept

Answer:

The value of "X" would be 2.

To solve for x, you'd have to get it by itself. To do so, you'd simplify both sides by solv8ng the exonents of each side (2^2 = 4) and (2^3 = 8). This leaves you with 4x = 8, which you'd then divide both sides by 4. Thus getting 2 as a final answer.

I hope this helps!

Answer:

√308 or 17.5

Step-by-step explanation:

c^2=a^2+b^2

c^2-a^2=b^2

Substitute

18^2-4^2=b^2

324-16=b^2

b^2=308

b=√308 or b=17.5

Answer:

​

65,536−1,024

which = 64,512 m^3

​

Step-by-step explanation:

I took the test!

The volume of the building shaped like a pyramid that's cut off in a plane parallel to its base is  64512 m³

volume of a pyramid = 1 / 3 Bh

where

Therefore,

volume of the building = volume of the whole figure - volume of the cut part

volume of the whole figure = 1 / 3 × (64 × 64) × (12 + 36)

volume of the whole figure = 65536 m³

volume of the cut part = 1 / 3 × (16 × 16) × (12)

volume of the cut part = 1024 m³

Therefore,

volume of the building = 65536 - 1024 = 64512 m³

Answer:

[tex]f^{-1}(x)=\sqrt{x}+2[/tex]

Step-by-step explanation:

Given function is,

f(x) = (x - 2)²

Step - 1

Rewrite the function in the form of a equation.

y = (x - 2)²

Step - 2

Interchange the variables 'x' and 'y',

x = (y - 2)²

Step - 3

Solve the equation for y,

x = (y - 2)²

y - 2 = √x

y = 2 + √x

Step - 4

Rewrite the equation in the form of a function,

[tex]f^{-1}(x)=\sqrt{x}+2[/tex]

Answer:

911.0145

Step-by-step explanation:

60,000 is the initial cost to repay and you add 49,321.74 because of interest

60,000+49,321.74= 109321.74 this is the final cost with interest

you divide by ten because there are ten years and you want it to equal 1 year

109321.74/10= 10932.174 this is the cost per year

last you divide by 12 because thats how many months there are per year

10932.174/12= 911.0145 this is the cost per month

Answer:

13:6 D

Step-by-step explanation:

A ratio is just a comparison between two numbers. its asking for pizza students first so you enter that number first then it asks for the number of mac and cheese so you input that number.

The ratio of students who ate pizza to students who ate mac and cheese is 13:6.

From the given table we need to find the ratio of students who ate pizza to students who ate mac and cheese.

In mathematics, a ratio indicates how many times one number contains another.

Now, pizza: mac and cheese=13:6

Therefore, the ratio of students who ate pizza to students who ate mac and cheese is 13:6.

Answer: ( x -2 ) inches

Step-by-step explanation:

Let x  = length of skirt.

Given: Christi first cuts 7 inches off the bottom of the skirt and then adds a 5-inch ruffle to the skirt's remaining bottom edge.

Cutting of length will be represented by a negative integer.

The expression best represents the final length of the skirt = x-7+5 inches

= x -2 inches

Hence, the expression best represents the final length of the skirt = ( x -2 ) inches

So, blue cubes be 2x

And, green cubes be 2x (4) 8x

Now the ratio is

Yellow: Blue: green

x:2x:8x

Answer:

x = 24 , y = 10, z = 17

Step-by-step explanation:

Given

6x - 29 = 115

6x = 115 + 29

6x = 144

x = 144 / 6

x = 24

3y - 1 = 29

3y = 29 + 1

3y = 30

y = 30 / 3

y = 10

4z - 32 = 36

4z = 36 + 32

4z = 68

z = 68 / 4

z = 17
