Jaxon was asked 40 questions on a test he answered 80% incorrectly how many did he get correct

Answers

Answer:

8 correct.

Step-by-step explanation:

80 / 100 = x / 40    (Since he got 80% INCORRECT you will subtract the value of x from 40)

100x = 80 x 40

x = 3200 / 100

x = 32

40 - 32 = 8

-6 - 2 (4x - 7) = -32

Answers

Answer:

x=5

Step-by-step explanation:

-6 - 2(4x - 7) = -32

Distribute -2

-6 - 8x +14 = 32

Combine Like Terms

-8x + 8 = -32

Subtract 8 from both sides

-8x = -40

Divide each side by -8

- x - = +

Diego measured the length of a pen to be 22 cm. The actual length of the pen is 23 cm. Which of these is closest to the percent error for Diego’s measurement. Explain your choice. [3 point]
4.3%
4.5%
95.7%
104.5%

Answers

Answer: its either a or b

Error is the difference between the actual length of an object and its measured length.

The closest to the percent error for Diego's measurement is 4.3%

Step 1: Find the error

Error = Actual length - Measured length

= 23cm - 22cm

= 1 cm

Step 2: Find the percent error

Formula = Error/ Actual length × 100

= 1 /23 × 10

= 4.35%

Therefore, the closest to the percent error for Diego's measurement is 4.3%

Answers

Answer:

Use synthetic division to solve

Step-by-step explanation:

When dividing a polynomial by a zero, you first want to find the zero to divide by. Solving the zero (x+2) will give us the value of x to divide by. Subtracting 2 from each side gives us x=-2. Then, we write out the full polynomial. Since the only degrees that have numerical values are x^5 and 32, we substitute zero for the values in between (0x^4, 0x^3, 0x^2, and 0x). Then we follow the steps of synthetic division (as seen in the photo) to find our new values for our new equation.

Answer:C

Step-by-step explanation:

The derivation of the quadratic function is true

What is Quadratic Equation?

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

The roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

where ( b² - 4ac ) is the discriminant

when ( b² - 4ac ) is positive, we get two real solutions

when discriminant is zero we get just one real solution (both answers are the same)

when discriminant is negative we get a pair of complex solutions

Given data ,

Let the quadratic equation be represented as A

Now , the value of A is

ax² + bx + c = 0

Step 1 :

ax² + bx + c = 0

Step 2 : Subtracting c on both sides , we get

ax² + bx = -c

Step 3 : Divide by x on both sides , we get

ax + b = -c/x

Hence , the steps are true in solving the quadratic equation

what is the perpendicular slope intercept form?​

Answers

Answer:

y = -1/2x + 2.5

Step-by-step explanation:

- slope of a perpendicular line is the negative reciprocal of the original slope (2 in this case) so y = -1/2 x + c

- to find c we substitute the values from the given point into the equation

(0) = -1/2*(5) + c

- rearrange and calculate and you'll get c = 5/2 or 2.5

- replace the value of c and now you've got y = -1/2x + 2.5

Given:

Number of  blue marbles, twice as many red marbles as blue, and 8 yellow marbles.

She has a total of 32 marbles.

To find:

The number of red marbles.

Solution:

Let number of blue marbles be x.

Then, number of red marbles = 2x

Number of yellow marbles = 8

Total number of marbles = 32

[tex]x+2x+8=32[/tex]

[tex]3x=32-8[/tex]

Now,

Number of red marbles [tex]=2(8)=16[/tex]

Therefore, there are 16 red marbles.

1.Two cyclists are 7 miles apart when they begin biking away from each other in opposite directions. The speed of the first cyclist is 12 miles per hour. The speed of the second cyclist is b miles per hour greater than the speed of the first cyclist.

How many miles does the first cyclist bike in 45 minutes?

Answers

Answer:

9 miles

Step-by-step explanation:

If 1 hour is 12 miles, then 30 mins is 6 miles, then 15 minutes is 3 miles.

30+15=45

6+3=9

The first cyclist bikes 9 miles in 45 minutes.

Since two cyclists are 7 miles apart when they begin biking away from each other in opposite directions, and the speed of the first cyclist is 12 miles per hour, to determine how many miles does the first cyclist bike in 45 minutes the following calculation must be done:

60 = 12 45 = X 45 x 12/60 = X 540/60 = X 9 = X

Therefore, the first cyclist bikes 9 miles in 45 minutes.
