The slope of the line below is -2. Use the cordinates of the labeled point to find a point-slope equation of the line

Answers

Answer 1

Answer:

We can not see the image, so i will answer this in a general way.

We know that a linear equation can be written as:

y = a*x + b

Where a is the slope, and b is the y-intercept.

In this case, we know that this line has a slope equal to -2, then the line is:

y = -2*x + b

Now, suppose that in the image we can see that this line passes through the point (j, k)

Then we can replace x by j, and y by k in the line equation, to get:

k = -2*j + b

Now we can solve this for b:

b = k + 2*j

Then we can conclude that a line with a slope equal to -2, that passes through the point (j, k) is:

y = -2*x + (k + 2*j)

y/8 = 40, y = 5

is this correct? yes or no

Answers

Answer: No, the correct answer is 320.

Step-by-step explanation: To solve for Y, simplify both sides of the equation, then isolate the variable.

Step 1: Multiply both sides by 8.

[tex](\frac{y}{8} )\times(8)=(40)\times(8)=320[/tex]

Therefore, your answer is incorrect, the correct answer is 320.

Bryans gocket team is purchasing jersys. The company charges $250 for the onetime set-up fee and $23 for each printed jersey which expression repressents the total cost of x number for the team

Answers

Given:

The company charges $250 for the onetime set-up fee and $23 for each printed jersey.

To find:

The expression that represents the total cost of x number for the team.

Solution:

We have,

Fixed charges = $250

Additional charges = $23 per printed jersey

Let x be the number of printed jersey. Then,

Additional charges = $23x

Total chargers = Fixed charges + Additional charges

                        = $(250 + 23x)

Therefore, the expression for the total charges is $(250 + 23x).

50.7 is what percent of 32? Round to the nearest tenth.

Answers

Question: 50 is what percent of 32?

Answer:156.25 or 156.3

Step 1: We make the assumption that 32 is 100% since it is our output value.

Step 2: We next represent the value we seek with x

Step 3:100%=32

Step 4:x%=50

Step 5:100%=32 x%=50(2)

Step 6:100%/x%=32/50

Step 7:x%/100=50/32 will give u 156.25% or round to the nearest tenth 156.3%

Answer:

56.3%

Step-by-step explanation:

0.5625×100= 56.25%

round to the nearest tenth.. which is 56.3%

The transformation from the function g(x)=x²-5 to h(x)=x²-1 is translation 4 units up. Therefore, option A is the correct answer.

What is a transformation?

A transformation is a general term for four specific ways to manipulate the shape and/or position of a point, a line, or geometric figure. The original shape of the object is called the Pre-Image and the final shape and position of the object is the Image under the transformation.

The given functions are g(x)=x²-5 and h(x)=x²-1.

From the function g(x)=x²-5 to h(x)=x²-1, the translation by 4 units up.

Now, g(x)=x²-5+4

So, h(x)=x²-1

Therefore, option A is the correct answer.

Answers

so convert them all to percentages

Anna: 19%
Laura: 17/20 then times by 5 to get 85%
therefore she saves 15%
David: 2:8 = 2/10 saved = 20%

so david saves the most

Switch Sides

mx + b = y

Subtract 'b' From Both Sides

mx + b - b = y - b

After 14 years, I shall be three times as old as I was 4 years ago. What is my present age?

Answers

Answer:

Present age = 13 years

Step-by-step explanation:

Let the present age be x years.

14 years after age = (x + 14) years

4 years ago age = (x - 4)

According to the given information:

14 years after age = 3 times 4 years ago age

x + 14 = 3(x - 4)

x + 14 = 3x - 12

14 + 12 = 3x - x

26 = 2x

x = 26/2

x = 13 years

Thus, the present age is 13 years
