Describe how you know whether an equation will be true for all values of x or true for no values of x.

Answers

Answer 1

Answer:

Substitute your answer for the variable x. If the equation looks accurate or is correct, then the value of x is the right answer. Not sure if this makes sense

Answer 2

Determining whether an equation is true for all values of x or true for no values of x requires simplifying the equation, determining its domain, checking for variable restrictions, and evaluating the equation for different values of x.

What is an equation?

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

Simplify the equation as much as possible using algebraic manipulations such as combining like terms, factoring, and expanding.

Evaluate the equation for a few different values of x to see if it holds true. If the equation is true for all values of x within the domain, then it will be true for all values of x. If there are any values of x within the domain that make the equation false, then it will be false for no values of x.

If the equation cannot be simplified or the domain cannot be determined, then it may require further analysis, such as graphing or using calculus techniques to determine its behavior.

Thus, determining whether an equation is true for all values of x or true for no values of x requires simplifying the equation, determining its domain, checking for variable restrictions, and evaluating the equation for different values of x.

The price of a pair of Jordans was reduced from $200 to $160. By percentage was the price reduced

help me

Answers

Answer:

20%

Step-by-step explanation:

The Jordans was reduced by 20% from $200 to $160.

1. Subtract 160 from 200 to find out the difference:

200 - 160 = $40

2. Since $40 was the difference. Divide 40 by 200 to find out the percentage:

40/200 = .2 = 20%

3. You can check this answer: 200 x .2 = 40.

Cubed-shaped boxes of candy are shipped in larger boxes. The larger boxes are six feet long, one foot wide, and two feet high. How many one cubic foot boxes of candy will the large box hold? Describe how you will solve the problem. Type in your answer.

Answers

Answer:

Step-by-step explanation:

The boxes of candy have a volume of 1 cubic foot.

We need to find the volume of the large shipping box in cubic feet, to see how many of the boxes of candy will fit inside.

The shipping box has the shape of a rectangular prism.

volume = length * width * height

volume = 6 ft * 1 ft * 2 ft

volume = 12 cubic ft

The shipping box has a volume of 12 cubic feet.

Since each box of candy has a volume of 1 cubic foot, we noww divide the volumes.

(12 cubic feet)/(1 cubic foot) = 12

Suppose you have a right triangle area marked in the ground with a base (8-h) meters long and a height h meters long. the hypotenuse is 6 meters long.

part a: what is the length of the height of the right triangle

Answers

Answer:

5.415m and 2.585m long

Step-by-step explanation:

For a right triangle

hyp^2 = opp^2 + adj^2 (Pythagoras theorem)

Given

hypotenuse = 6m

height(opposite) = h meters

Adjacent = (8-h)m

Substitute into the expression above;

6² = h²+(8-h)²

36 = h²+64-16h+h²

36 = 2h²-16h+64

2h²-16h+64-36 = 0

2h²-16h+28= 0

Divide through by 2

h²-8h+14 = 0

Using the general formula

h = 8±√8²-4(14)/2

h = 8±√64-56/2

h = 8±√8/2

h = 8±2.83/2

h = 8+2.83/2 and 8-2.83/2

h = 10.83/2 and 5.17/2

h = 5.415 and 2.585

hence the length of the height of the right triangle are 5.415m and 2.585m long

Find the volume of triangular prism with the following dimensions. Round to the nearest whole number.
Triangle base= 7 ft.
triangle height= 4 ft
prism height: 8.5 ft

Answers

Answer:

124.0 ft^2

Step-by-step explanation:

let b = base of triangle = 7ft

h = height of triangle = 4ft

and

l = height of prism. = 8.5ft

We know,

volume of prism = area of triangular face of prizm × height of prizm

= 1/2 × b × h × l

= 1/2 × 7 × 4 × 8.5

= 7 × 2 × 8.5

= 14 × 8.5

= 124.0 ft^2

Together, teammates Pedro and Ricky got 2680 base hits last season. Pedro had 276 more hits than Ricky. How many hits did each player have?

Answers

Answer:

Ricky it is 1,202

And for Pedro = 1,202 + 276 = 1,478

Step-by-step explanation:

The computation is shown below:

Let us assume the ricky be x

So pedro be x + 276

Now the equation is

x + x + 276 = 2680

2x + 276 = 2680

2x = 2680 - 276

2x = 2404

x = 1,202

For Ricky it is 1,202

And for Pedro = 1,202 + 276 = 1,478
