Find slope(m) and Y-intercept(b)
Make sure to write in standard form, y = mx + b for each
problem
1. y = 7x + 9
2. y=-5x-2
3. y = 3x + 1

Answers

Answer 1

Answer:

1. slope is 7 and y-intercept is 9

2.slope is -5 and y-intercept is -2

3. slope is 3 and y-intercept is 1

Step-by-step explanation:

The standard equation of a line in slope form is;

y=mx + b where m is the slope and b is the y intercept.

In question 1.

y=7x + 9

slope is 7 and y-intercept is 9

In question 2

y= -5x - 2

slope is -5 and y-intercept is -2

In question 3

y= 3x + 1

slope is 3 and y-intercept is 1

Write an absolute value inequality that represents the situation. Then solve the inequality the difference between the areas of the figure is less than 2.



The absolute value inequality is________<2


The solution of inequality is_______.

Answers

Answer:

Absolute value inequality is |(2x + 12) - 12| < 2

Solution of the inequality is -1 < x < 1 (x = -1 or x = 1)

Step-by-step explanation:

Area of triangle = ½*base*height = ½*4*(x + 6) = 2(x + 6) = 2x + 12

Area of rectangle = length * width = 6*2 = 12

Given that the difference their areas is less than two, therefore, an absolute value inequality can be written as follows:

|(2x + 12) - 12| < 2

Find the solution by splitting the inequality into two:

(2x + 12) - 12 < 2 OR (2x + 12) - 12 > -2

Solve each

2x + 12 - 12 < 2

2x < 2

2x/2 < 2/2

x < 1

OR

2x + 12 - 12 > -2

2x > -2

2x/2 > -2/2

x > -1

Solution would be -1 < x < 1 (x = -1 or x = 1)

The first question is the numbers 16 and above.

Number line!

using a number line you can go from -15 to then go to the right until you get to +1.

Count the spaces.

(You can also think of this as debt which I find much easier.)

The second question would be 14 and under.

Any answer from 14 and under will lead to a negative answer, which is less than 0.

You can use a number line to help you with this one as well,

Start from -15 then go the right until you reach -1.

count the spaces.

The last one is 15.

Number line, once again.

start at -15 then go to the right until you reach 0.

count the spaces.

Answers

Answer:

f(x)=|1/2x|

Step-by-step explanation:

Answer:

y=l(1/4)x + (1/2)l

Step-by-step explanation:

When shifting non-linear functions to the left or right, you must put the opposite operation inside the parenthesis. This means when you move to the left, your number must be positive. If you move to the right, your number must be negative. In this scenario, we want to shift the graph to the left 2 units. However, because our m value is a fraction, the shifting vale must also be a fraction. So instead of 2, the value becomes (1/2). Putting this all together, your answer is y=l(1/4)x + (1/2)l

What is Fraction?

The fractional bar is a horizontal bar that divides the numerator and denominator of every fraction into these two halves.

The number of parts into which the whole has been divided is shown by the denominator. It is positioned in the fraction's lower portion, below the fractional bar.How many sections of the fraction are displayed or chosen is shown in the numerator. It is positioned above the fractional bar in the upper portion of the fraction.

Given:

3/4x+1/4y=5

Now, solve for y

1/4 y= 5 - 3/4x

y = 4( 5 -3/4x)

y = 20- 3x

Hence, the value of y is 20- 3x.

Food storage contains labeled with a 1.5 quart capacity must have an acutal capacity within 0.02 quarts of the capacity stated on the label. Select the equation that represnets the minimum actual capacity and maximum actual capacity allowed for products labeled as 1.5 quart food storage containers.

Answers

Answer:

Kindly check explanation

Step-by-step explanation:

Given that:

If Capacity on label = 1.5 quarts

Actual capacity will be within 0.02 quartz of the capacity stated on label

The actual capacity of the container labeled 1.5 quarts will hence equal:

Let actual capacity = a

| a - capacity in label | = 0.02

| a - 1.5 | = ± 0.02

a - 1.5 = ± 0.02

Hence,

Minimum actual capacity :

a = - 0.02 + 1.5 = 1.48

Maximum actual capacity :

a = 0.02 + 1.5 = 1.52

You created a new playlist and 100 of your friends listened to it and shared it if they liked the new playlist or not Keyshaun said the ratio of the number of people who did not like the playlist is 75:25 Maddox said that for every three people who liked the playlist one person did not Do Keyshaun and Maddox agree

Answers

Answer:

No

Step-by-step explanation:

From the information provided, we can say that both Keyshaun and Maddox have the same ratio since 25 goes into 75 three times which means that Keyshauns 75:25 ratio is the same as Maddox's 3:1 ratio. Although, even though both ratios are the same, Keyshaun and Maddox do not agree since Keyshaun believes that there is a 3:1 ratio favoring people that do not like the playlist, while Maddox believes there is a 3:1 ratio favoring people who do like the playlist. Therefore they have opposite beliefs.

What is the slope of a line perpendicular to a line with slope –9?

Answers

Answer:

The answer is 1/9.

Step-by-step explanation:

When solving for the slope of a perpendicular line to a given, you have to flip the opposite reciprocal.

First take the number and flip the reciprocal, in this case -9 turns into -1/9.

Then flip the sign, like making a negative to a positive or a positive to a negative. In this case make -1/9 into 1/9

Therefore the answer is 1/9.

Answer:

The general equation following the pattern becomes is 7 + (n - 1)×2

Where, n = The figure number - 1

Step-by-step explanation:

The pattern in the question can be described as follows;

Figure 2 = (5 + 2) squares boxes = 7 squares boxes

Figure 3 = (5 + 2 + 2) squares boxes

Figure 4 = (5 + 2 + 2 + 2) squares boxes

Therefore, the number of squares boxes per figure, form an arithmetic progression (a + (n - 1)d) with the first term a = 7, the common difference d = 2, and the n = the nth term of the series, such that the general equation following the pattern becomes;
