Solve the equation using the quadratic formula. 262 – 3b+85=-5

Answers

Answer 1

Answer:

b= 352/3

or b= 117.33

Step-by-step explanation:

262-3x+85=-5

-3x+(262+85)=-5

simplify the arithmetic

-3x+347=-5

Group all constants on the right side of the equation

-3x+347=-5

Subtract  from both sides:

-3x+347-347=-5-347

Simplify the arithmetic:

-3x=-5-347

-3x=-352

isolate the x

-3x=-352

Divide both sides by -3

-3x/-3}=-352/-3}

Cancel out the negatives

3x/3}=-352/-3

Simplify the fraction

x= -352/-3

Cancel out the negatives

x=352/3

Answers

Answer:

x= 10, y= 6

Step-by-step explanation:

2x -3y= 2 -----(1)

-2x -y= -26 -----(2)

(1) +(2):

2x -3y -2x -y= 2 -26

-4y= -24

y= -24 ÷(-4)

y= 6

Substitute y= 6 into (1):

2x -3(6)= 2

2x -18= 2

2x= 18 +2

2x= 20

Divide both sides by 2:

x= 20 ÷2

Thaddeus shakes his head as he pays $12.37 to the clerk for lunch. Complaining to a friend, Thaddeus says, “Do you realize that is 0.2% of my monthly income?” His friend replies, “I think you made a mistake. That should be 2%. You messed up on the decimal point.” (a) Assuming Thaddeus is not wrong, what is his monthly income? (b) If Thaddeus’ friend is correct, what is Thaddeus’ monthly income?

Answers

Answer:

a) If Thaddeus is not wrong, his monthly income is $6,185.

x/12.37 = 100/0.2

0.2x = 1237

x = 1237/0.2x

x = 6,185

b) If Thaddeus's friend is correct, Thaddeus's monthly income is $618.5

x/12.37 = 100/2

2x = 1237

x = 1237/2x

x = 618.5

If Thaddeus is not wrong, his monthly income is $6,185.

If Thaddeus's friend is correct, Thaddeus's monthly income is $618.5.

What is Algebra?

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:

Thaddeus shakes his head as he pays $12.37 to the clerk for lunch.

a) If Thaddeus is not wrong then let his income be x.

So, x/12.37 = 100/0.2

0.2x = 1237

x = 1237/0.2x

x = 6,185

b) If Thaddeus's friend is correct

x/12.37 = 100/2

2x = 1237

x = 1237/2x

x = 618.5

Part II: Find the slope of line p. (Write the negative reciprocal of the slope you found
in Part I.)

y = 3x + 5 ← is in slope- intercept form

with m = 3

What is the y-intercept of the line shown below?
A. 5
B. -5
C. 2
D. -2

Answers

Answer: -2

Step-by-step explanation: The y-intercept of a line is the point where the graph crosses or intersects the y-axis.

In this case, the line crosses the y-axis 2 units down from the

origin and we can write the coordinates of the point as (0, -2).

So the answer is -2.

-2 because that is where the line crosses the y axis


What is the slope of the line that passes through the points (6,2) and (-18. 2)?

Answers

Answer:

undefined

Step-by-step explanation:

slope of a line = m

m = (y1-y2) / (x1-x2)

m = (2-2) / (6 - -18)

m = 0 / (6+24)

m = 0/30

m = undefined

The slope of the line that passes through these two points is 0.

What is the slope of the line?

If we know that a line passes through two points (a, b) and (c, d), then the slope is given by the following expression:

slope = (d - b)/(c - a)

Here the two points are (6, 2) and (-18, 2)

Then the slope is:

slope = (2 - 2)/(-18 - 6) = 0/-24 = 0

The slope is 0, so this is a horizontal line.

The height of a ball in meters is modeled by fx 5x 2 50x, where x is the time in seconds after it is hit. How long is the ball in the air

Answers

Answer:

Equation is incorrect

Step-by-step explanation:

The equation is not written correctly.  It is written with no arithmetic signs linking the expressions.  One might assume it is f(x) = 5x^2 + 50x, but even so, something is still wrong.  

The equation tells us that the ball will never return to the ground after it is hit.   There are no nonzero positive values of time, x in seconds) for which this equation will produce the "0" for the height at ground level.

Answers

The  actual degree measure of arc KJ is 99 degrees

Circle geometry

From the given informtion

arc KL = 12x+4

arc KJ = 8x-6

<E = 99 degrees

The equation required to get the value of "x" is given as:

12x + 4 + 8x - 6 + 99 = 360

20x + 97 = 360

20x = 360 - 97

20x = 263

x = 13.15

For the arcKL

arcKJ = 8(13.15) -  6

arcKJ = 99degrees

HEnce the  actual degree measure of arc KJ is 99 degrees
