Answer:

x [tex]\leq[/tex] 3

Step-by-step explanation:

[tex]\frac{1}{2}[/tex] - [tex]\frac{1}{4}[/tex]x [tex]\geq[/tex] - [tex]\frac{1}{4}[/tex]

the first step is to subtract [tex]\frac{1}{2}[/tex] from both sides of the equation.

[tex]\frac{1}{2}[/tex] - [tex]\frac{1}{4}[/tex]x [tex]\geq[/tex] - [tex]\frac{1}{4}[/tex]

-[tex]\frac{1}{2}[/tex]         - [tex]\frac{1}{2}[/tex]

----------------

-[tex]\frac{1}{4}[/tex]x [tex]\geq[/tex] - [tex]\frac{3}{4}[/tex]

then, divide both sides of the equation by - [tex]\frac{1}{4}[/tex].

x [tex]\leq[/tex] 3

(since we divided both sides by a negative number, to isolate x, the [tex]\geq[/tex] changed to [tex]\leq[/tex].)

Answer:

1/2 - 1/4x ≥ -1/4

multiply both sides by the l.c.m of the both sides(4)

4(1/2 - 1/4x )≥ -1/4 ×4

2 - x ≥ -1

Collect the like terms

-x ≥ -3

Divide both sides by -1

x ≤ 3(when you divide by a negative number the equality changes)

The fomula is y=mx+b

The number before x is the slope! Rise over run.

The + __ number is the y-intersect. use this number to place a point on the Y line.

Step-by-step explanation:

[tex]\sf \leadsto \dfrac{5y - 2}{4(y + 2)} = \dfrac{1}{3}[/tex]

Answer:

[tex]\huge\boxed{\sf x\° = 31.8\°}[/tex]

Step-by-step explanation:

Using one of the trigonometric ratios.

sin x° = opposite / hypotenuse

Where: opposite = 39, hypotenuse = 74

sin x° = 39/74

x° = sin⁻¹ 39 / 74

x° = 31.8°

17/1=17

90+17=107

Step-by-step explanation:

Answer:

wouldn't it be 17 meters?

=========================================================

Explanation:

Draw a right triangle. The horizontal leg is 8 meters. The hypotenuse is 9 meters. The vertical height is unknown, so we'll call it x.

Apply the pythagorean theorem to solve for x

[tex]a^2 + b^2 = c^2\\\\8^2 + x^2 = 9^2\\\\64 + x^2 = 81\\\\x^2 = 81-64\\\\x^2 = 17\\\\x = \sqrt{17}\\\\x \approx 4.1231056\\\\x \approx 4.12\\\\[/tex]

Answer:

The answer should be 22.6, 33.9, 56.5, and 90.4

Step-by-step explanation:

The 11.3 stands for the time it takes to make one burger. The h stands for how many burgers. So for every burger you make, you simply multiply by 11.3

Range: lowest possible y-value to the highest possible y-value

In this case, the graph spans from -4 to 1, taking on all of the y-values between those two points. But, the graph also has a straight line at y=3.

Range: -4 < y <= 1 or {3}

The amount of money Calvin and Sasha have, is an illustration of equivalent expressions.

Calvin has exactly 13 quarters

From the question, we have:

[tex]\mathbf{Calvin = 0.25Q}[/tex]

[tex]\mathbf{Sasha = 0.05N + 0.01P + 0.10D}[/tex]

Calvin has the same number of quarters as Sasha has dimes.

So, we have:

[tex]\mathbf{Q = D}[/tex]

Sasha has $1.95 in coins that are not dimes.

So, we have

[tex]\mathbf{0.05N +0.01P = 1.95}[/tex]

They have the same amount of money i.e.

[tex]\mathbf{Calvin = Sasha}[/tex]

This gives

[tex]\mathbf{0.25Q = 0.05N + 0.01P + 0.10D }[/tex]

Substitute [tex]\mathbf{0.05N +0.01P = 1.95}[/tex]

[tex]\mathbf{0.25Q = 1.95 + 0.10D }[/tex]

Substitute [tex]\mathbf{Q = D}[/tex]

[tex]\mathbf{0.25Q = 1.95 + 0.10Q }[/tex]

Collect like terms

[tex]\mathbf{0.25Q -0.10Q= 1.95 }\\[/tex]

[tex]\mathbf{0.15Q= 1.95 }[/tex]

Divide both sides by 0.15

[tex]\mathbf{Q= 13 }[/tex]

Hence, Calvin has exactly 13 quarters

Answer:

C, 10^3

Step-by-step explanation:

To get from 22 to 22000, you need to times by 1000. The power in this case represents the amount of zeros added to a number. Hope this helped!

10³ multiply 22 by to get an answer of 22,000.

The correct option is (D)

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

We have to multiply 22 such that it gives 22, 000.

let the number that being multiplied be x.

So, 22x = 22000

x= 22000/22

x= 1000

x= 10³

Hence, 10³ multiply 22 by to get an answer of 22,000.
