Answer 1

Answer:

1.)x=-5, x=3

2.)√10+4, x=√10+4

Step-by-step explanation:

1.) 2(x+1)^2=32

(x+1)^2=16

x+1=±4

x=1=-4

x=1=4

x=-5, x=3

2.)3(x-4)^2=30

(x-4)^2=10

x-4=±√10

x-4=-√10

x-4=√10

x=-√10+4, x=√10+4

Find the equation parallel to y = -x - 5 and passing through (-3, -3)

Answers

Answer:

y = -x - 6

Step-by-step explanation:

If it's parallel, then it means that the slope will remain the same. The slope is

-1.

To find the y-intercept, you need to plug the coordinates into the equation,

y = -1x + b

-3 = -1(-3) + b

-3 = 3 +b

-6 = b

The equation is y = -x - 6

graph 3x+6y=18 In the box below, enter the y value when x = 2.

Answers

Answer:

y = 2

Step-by-step explanation:

3x + 6y = 18

3(2) + 6y = 18

6 + 6y = 18

Since 18 - 6 = 12, y will equal 2.

6 + 6(2) = 18

6 + 12 = 18

The coordinates to graph the equation would be (2, 2).

Hope it helps!

A scientist planted seeds in 4 sections of soil for an experiment. Not all of the
seeds grew into plants. After 20 days, the scientist counted the number of
plants in each of the 4 sections. The results are shown in the table.
• Use the data in the table to determine approximately how many plants
grew per square foot.
• Explain or show how you determined your approximation.
• Let y be the number of plants expected to grow in x square feet. Write an
equation the scientist could use to model the relationship between y and x.

Answers

Answer:

I think you would multiply 20 × 4 and the answer would be 80 that the scientist counted the number of plants in each 4 sections after 20 days.

The number of plants per square foot will be; 48.

Given that scientist planted seeds in 4 sections of soil for an experiment. Not all of the seeds grew into plants. After 20 days, the scientist counted the number of plants in each of the 4 sections.

What is addition?

The addition is one of the mathematical operations. The addition of two numbers results in the total amount of the combined value.

The number of plants per square foot:

= (25 × 13) + (100 × 38) + (125 × 47) + (150 × 62) / (25 + 100 + 125 + 150)

= (325 + 3800 + 5875 + 9300) / 400

= 48.25

Thus, it was illustrated by the number of plants and size of sections.

Thus, the number of plants per square foot will be 48.

Answers

Answer: 9 x + 7 /2

Step-by-step explanation:

Answer:

 8 + 9x

Step-by-step explanation:

This is an algebraic expression.  Our job here is to simplify it by combining like terms:  combine the x terms and then combine the constants:

-3x + 5 ¾ + 12x - 2.25, after combining the x terms, is

       5 ¾ +    9x - 2.25

Next, combine the constants.  It's easier to convert -2.25 to -2 1/4 and then

add this 2 1/4 to 5 3/4:  

             8 + 9x

Dr. Baker, a veterinarian, recorded the weight of each newborn kitten her office saw today.
Kittens' weights (g)
100
120
140
160
180
200

Answers

Answer:

30 grams is the answer

As per the given data, the interquartile range of the kittens' weights is 60 g.

What is interquartile range?

The interquartile range (IQR) is a measure of variability, based on dividing a data set into quartiles.

The IQR is the range between the first quartile (Q1) and the third quartile (Q3). It represents the range of the middle 50% of the data set.

To find the interquartile range (IQR) of the kittens' weights, we need to first find the median and the quartiles.

Find the median (Q2):

The median is the middle value when the data is arranged in order. In this case, we have an even number of data points, so we take the average of the two middle values:

100, 120, 140, 160, 180, 200

The middle values are 140 and 160, so the median is:

(Q2) = (140 + 160) / 2 = 150

Find the first quartile (Q1):

The first quartile is the middle value of the lower half of the data. To find Q1, we take the median of the lower half:

100, 120, 140

The median is 120, so Q1 is:

Q1 = 120

Find the third quartile (Q3):

The third quartile is the middle value of the upper half of the data. To find Q3, we take the median of the upper half:

160, 180, 200

The median is 180, so Q3 is:

Q3 = 180

Calculate the interquartile range:

The interquartile range is the difference between the third and first quartiles:

IQR = Q3 - Q1 = 180 - 120 = 60

Therefore, the interquartile range of the kittens' weights is 60 g.
