Yes you did great job

that’s what I thought first, but the things right. each x value IS associated with only one y value. If there was more than one arrow pointing from one x value, it wouldn’t be a function, because it would mean one x value has more than one y value. I hope that made sense!

Tyrod needs at least $820 to buy the computer he wants. He has already saved $330. He earns $50 per lawn that he cuts. What is the least number of lawns that he can cut and buy the computer? Which inequality represents the problem?​

Answers

[tex]▪▪▪▪▪▪▪▪▪▪▪▪▪  {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪[/tex]

The equation representing the given statement is ~

[tex]50x + 330 \geqslant 820[/tex]

The least number of lawns that he can cut and buy the computer is 10 lawns ~

[tex] \large \boxed{ \mathfrak{Step\:\: By\:\:Step\:\:Explanation}}[/tex]

Total savings should be greater or equal to $ 820 in order to buy the computer,

And his total savinga is equal to ~

Money he saved + money got from cutting lawns.

let's assume the lawns cut by Tyrod be x,

Money earned by cutting lawns is equal to

total number of lawns cut × $50

50x

total savings is equal to ~

330 + 50x

hence,

[tex]50x + 330 \geqslant 820[/tex]

by solving for " x (number of lawns cut) " we get ~

[tex]50x \geqslant 820 - 330[/tex]

[tex]50x \geqslant 490[/tex]

[tex]x \geqslant 490 \div 50[/tex]

[tex]x \geqslant 9.8[/tex]

Hence, the least number of lawns he has to cut is the number that is greater than 9.8, which is

Which value is equivalent to the expression 7^2 − 3^4?
A) -3^2
B) -1^9
C) 1^6
D) 3^2

Answers

Answer:

Option B

Step-by-step explanation:

Answer:

None of these are equal to the equation in question.

When solved 7^2 - 3^4 = -32

-3^2 = -9

-1^9 = -1

1^6 = 1

3^2 = 9

So none of the answer choices are equal to the equation in question.

Answers

Answer:

See below:

Step-by-step explanation:

The term [tex]f(x)[/tex] is used to show the function of x and is essentially the same as y in some cases. One being right now.

So we know the function [tex]T(n)[/tex] and we know that we want to solve for [tex]T(12)[/tex].

So what we can do, is input 12 as n in the original function.

Therefore, we get [tex]T(12)=\frac{2}{3} (12) + 3[/tex]

Using algebra, we can solve it and we get 11!

solve for x, find the measure of all angles plzzzzz!! ​

Answers

Answer:

∠ H = 22.5°, ∠ I = 45° , ∡ J = 112.5°

Step-by-step explanation:

The 3 angles in a triangle sum to 180° , then

x + 2x + 5x = 180 , that is

8x = 180 ( divide both sides by 8 )

x = 22.5

Then

∠ H = x = 22.5°

∠ I = 2x = 2 × 22.5° = 45°

∠ J = 5x = 5 × 22.5° = 112.5°

Complete the puzzle so that each row, column, and diagonal adds up to the same total.

Answers

Answer:

0 , 5

-1 , 1

-3

Step-by-step explanation:

Each row, column and diagonal adds up to 3 because of the column on the right.

The bottom row must add up to 3, so the blank there is -3.

The diagonal from the bottom left corner to the upper right corner also must add up to 3, so the blank in the middle is 1.

The column in the middle must add up to 3, so the blank at the top is 5.

The top row also must equal to 3, so the blank on the left is 0.

The left column also must equal to 3, so the last blank left is -1.

Which equation has no solution?
A.

B.

C.

D.

Answers

Answer:

  C.

Step-by-step explanation:

The equation will have no solution if it reduces to the form ...

  1 = 0

Other possible forms are ...

  0 = 0 . . . . infinite solutions

  y + c = 0 . . . . one solution

___

The given equations can be reduced to one of these forms by subtracting the right-side expression from both sides.

  A. 2.3y +2 +3.1y -(4.3y +1.6 +1.1y +0.4) = 0   ⇒   0 = 0   (infinite solutions)

Firstly observe the Digit term of the given operation under scientific notation. and now we are left with the 10th exponents which involves the basics of 10^a - 10^b = 10^a/b and so according to this rule...we have 10^2/10^4 which results in 10^-2
