Which equation has infinitely many solutions?

A. -5(x + 2) = -4x − 12 − x + 2


B. 3x − 4 + 2x = 5(x − 4)


C. 5(x + 7) = -5(x − 7)


D. 6x + 2 − x = -2x − 2 + 7x

Answers

Answer 1

9514 1404 393

Answer:

  A

Step-by-step explanation:

We can eliminate parentheses, collect terms, and subtract the right-side expression from both sides to put these equations in general form. Then it is very easy to tell how many solutions there are .

A. -5x -10 = -5x -10

  0 = 0 . . . . . true for all values of x; infinite solutions

B. 5x -4 = 5x -20

  16 = 0 . . . . . not true for any value of x; no solutions

C. 5x +35 = -5x +35

  10x = 0 . . . . . true for x=0; one solution

D. 5x +2 = 5x -2

  4 = 0 . . . . . not true for any value of x; no solutions

Answer:

Let the chord- part of VC inside smaller circle be a, and same of CU be b.

According to intersecting secants theorem we have:

CI * (CI + a) = CJ * (CJ + b)

and

VC *(CI + a) = CU * (CJ + b)

From the second equation we get:

CU = VC * (CI + a) / (CJ + b)

From the first equation we get:

CI + a = CJ * (CJ + b) / CI,

substitute this into the second equation:

CU = VC * CJ * (CJ + b) / CI * 1/ (CJ + b)CU = VC * CJ / CICU * CI = VC * CJ

There are 4 triangles with base of 5 and height of 8.4

Area of triangle = 1/2 x base x height

Area of triangle = 1/2 x 5 x 8.4 = 21 m^2

Multiply by 4 = 21 x 4 = 84 m^2

Area of the base = length x width = 5 x 5 = 25 m^2

Total area = 84 + 25 = 109 m^2

You work as an assistant to a carpenter who designed the tabletop below. He tells you that each shape is a right triangle, and each is the same size. You now need to calculate the area of one triangle so that you can begin building the tabletop. What is the area of each triangle in square inches? 28 1/4" and 20"

Answers

Answer:

282.5 inches squared

Step-by-step explanation:

A triangle is half the area of a square.

So we will solve the area as if we were finding the area for a square, and then we halve the result.

Length multiply by height to get the area:

28.25 × 20 = 565 inches squared

Now, half the answer to get the area of the triangle:

565/2=282.5 inches squared

If why varies with the square of x and Y equals 24 when x equals 10 then the constant of proportionality is ____, and the value of y when x equals 20 is ____. Assume x is greater than or equal to 0. Select two answers

Answers

Answer:

Step-by-step explanation:

y varies with the square of x:

y = kx²

y equals 24 when x equals 10

24 = k·10²

constant of proportionality k = 0.24

when x = 20, y = 0.24·20² = 96

Help

Answers

Answer:

The width is 36 feet

Step-by-step explanation:

If the width of the fence is x then its length is x+3.

The perimeter is 150 feet, so we have the equation:

6

= 2 · 6 + 5/

6

6

= 17/

6

To find new numerator:

a) Multiply the whole number 2 by the denominator 6. Whole number 2 equally 2 * 6/

6

= 12/

6

b) Add the answer from previous step 12 to the numerator 5. New numerator is 12 + 5 = 17

c) Write a previous answer (new numerator 17) over the denominator 6.

To find new numerator:

a) Multiply the whole number 5 by the denominator 4. Whole number 5 equally 5 * 4/

4

b) Add the answer from previous step 20 to the numerator 1. New numerator is 20 + 1 = 21

c) Write a previous answer (new numerator 21) over the denominator 4.

8 · 21

= -28/

168

= 28 · (-1)/

28 · 6

= -1/

6

Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 21/

4

is 4/

21

) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the next intermediate step, the fraction result cannot be further simplified by canceling.

In words - minus seven eighths divided by twenty-one quarters = minus one sixth.

Add: the result of step No. 2 + the result of step No. 4 = -17/

6

+ (-1/

6

) = -17 + (-1)/

6

= -18/

6

= 6 · -3/

6 · 1

= -3

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(6, 6) = 6. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 6 × 6 = 36.

In words - minus seventeen sixths plus minus one sixth = minus three.

So a total of 15 + 22 + 17 = 54.

Rachelle:

24 on Monday, 18 on Tuesday, 11 on Wednesday.

So a total of 24 + 18 + 11 = 53.

Who has processed the most accounts this week, and by how many?

54 - 53 = 1, so Luisa processed the most accounts this week, by 1.
