-3x+y=7


A. (–2, 2)


B. (–5, –8)


C. (5, 2)


D. (0, 7)

Answer:

12 cm

Step-by-step explanation:

OP = √(15² - (18/2)²)

=√(225- 9²)

=√(225-81)

=√144

= 12

Answer:

Point-slope form: y + 3= -1(x + 4)

Slope-intercept form: y = -1x - 7

y = m * x + b,

where:

m is the slope; and

b is the intercept of the y-axis.

Answer:

[tex]y=\frac{-2}{3}x+8[/tex]

Step-by-step explanation:

Hi there!

Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)

1) Determine the slope (m)

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] where the given points [tex](x_1,y_1)[/tex] are [tex](x_2,y_2)[/tex]

Plug in the given points (0,8) and (3,6)

[tex]m=\frac{6-8}{3-0}\\m=\frac{-2}{3}[/tex]

Therefore the slope of the line is [tex]\frac{-2}{3}[/tex]. Plug this into [tex]y=mx+b[/tex]:

[tex]y=\frac{-2}{3}x+b[/tex]

2) Determine the y-intercept (b)

[tex]y=\frac{-2}{3}x+b[/tex]

The y-intercept occurs when x=0. One of the given points is (0,8), so therefore, the y-intercept is 8. Plug this into [tex]y=\frac{-2}{3}x+b[/tex]:

[tex]y=\frac{-2}{3}x+8[/tex]

I hope this helps!

Answer:

Answer B.

x² + 1

Step-by-step explanation:

x=1

Input x= 1 into x²+1 to get y

(1)²+1 = 2

when x=2

(2)²+1 = 5

when x = 3

(3)² + 1 = 10.

when x=4

(4)² + 1 = 17

Hence Option B

Answer:

40.81 centimeters is the corrects answer. use addition to add them all together

Answer and Step-by-step explanation:

Here is the equation for finding the sides (just to show):

68 = (2L + 2W)

We multiply L and W by 2 because there are two of the lengths and 2 of the widths.

Now, we add the scale factor to the outside, but on both sides of the equation.

68 × 1.5 = 1.5(2L + 2W)

Multiply 68 by 1.5.

102 = 1.5(2L + 2W)

The answer is 102.

The perimeter of the resulting rectangle is 102 ft.

Answer:

Surface area?

4 x 3.5 x 1/2 (basically just dividing by 2) = 7

11.1 x 4 x 1/2(basically just dividing by 2) = 22.2,                                              22.2 x 3(three triangles on the sides) = 66.6

Now let's add all the given areas:

7 + 66.6 = 73.6 m^2 is your answer.

[tex]3^{3} + 5[/tex]

27 + 5

Answer:

32

Step-by-step explanation:

x^3+5

Answer:

Discriminant= b²-4ac

a = 9 b = -3 and c = -2

Discriminant = (-3)² - 4(9)(-2)

= 9+72

Discriminant = 81

Ans = 81

Answer:

20/t members are on the team

Step-by-step explanation:

From the question, we want to get the number of people on the team

20 T-shirts were bought

each of the team members got t T-shirts

To know the number of people on the team, we have to divide the number of shirts bought by the number of shirts gotten by each team member

We simply have this as 20/t

Answer:

b

Step-by-step explanation:

because 1/2 (13f+5)=9f and

6.5f+5=11.5 so tha's not rightt

6.5f+2.5=9f right

36f=not right

9f=not right

Answer: x = 24 & x = 96

Step-by-step explanation:

Answer: Every option given is a solution

Any value larger than 18 is a solution. So we can say x > 18.

============================================================

Explanation:

To isolate x, we multiply both sides by 6 like so

3 < x/6

3*6 < x

18 < x

x > 18

In the last step, I swapped the left and right sides. This swap meant that I had to flip the inequality sign as well. Saying x > 18 means we can pick anything larger than 18 to have it as a solution. Something like x = 5 is too small, but values like x = 24 and x = 96 will work. In fact, all of the answer choices given are larger than 18. So you'll check each answer box.

---------

As a way to confirm a potential answer, we plug it back into the original inequality. Let's say we wanted to check x = 90

So,

3 < x/6

3 < 90/6 ... replace every x with 90

3 < 15

The last inequality is true, because 3 is indeed smaller than 15. Therefore, the original inequality is true when x = 90. We confirm that x = 90 is a solution.

The steps to confirm x = 114, x = 96, and x = 24 will follow the same idea. I'll let you do those confirmations.

Answer:

option 3

Step-by-step explanation:

divide the diameter by 2 to get the radius.

pi×r^2

3.14×42^2=5538.96 km^2

Answer:

The period of the tangent function is π because the graph repeats itself on intervals of kπ where k is a constant. If we graph the tangent function on −π2 to π2 , we can see the behavior of the graph on one complete cycle.

The tangent function does not have an amplitude because it has no maximum or minimum value. The period of a tangent function, y=atan(bx) , is the distance between any two consecutive vertical asymptotes..

so its not 1 but 2.

hope its right.

Answer:

A is equal to 20.

Step-by-step explanation:

To find the missing side we have to square both 21 and 29.

 Because 21 x 21 = 441, and 29 x 29 = 841, all we have to do is subtract 841 from 441 and we have 400.

 Now we have to find the square root of 400, since 20 x 20 = 400, that means 20 is our answer.

Answer:

negative value for r

Step-by-step explanation:

Given data

Given the exponential function A(x)= P (1+r)^x

A negative value for r will make the function a decay

Hence the decay function will look like

A(x)= P (1-r)^x

Answer:

$8835.75

Step-by-step explanation:

The equation to use for this is for the area of a circle which is:

π r^2

So by plugging in 15 feet:

π 15^2,

π 225,

~706.86 ft^2.

Next, multiply this by the $12.50 per square foot.

706.86 * 12.50 = $8835.75

All done!

Answer:

min 1

Q1 = 6

med = 12.5

Q3 = 14

Max = 19

Step-by-step explanation:

Min simply refers to the smallest value and that is 1

Q1 is the first quartile and the formula is;

Q1 = (n+ 1)/4

where n is the number of terms which is 10

Q1 = (10 + 1)/4 = 2.75

This is approximately 3 and the 3rd term is 6

med is the median value and that is 12 + 13 = 25/2 = 12.5

Q3 is the third quartile

Q3 = 3(n+ 1)/4 = 8.25 and that is the 8th term which is 14

Max is simply the highest in value and that is 19

Answer:

B. The point (17, 12) could cause the description of the data set to be understated.

Step-by-step explanation:

All other points on the scatter plot except point (17, 12), all follow a similar trend showing the negative relation between height of plants and darkness. If we are to consider just point (17, 12) alone when describing the data set, we might likely understate the relation between both variables.

Therefore, the statement that is true about the scatter plot is "B. The point (17, 12) could cause the description of the data set to be understated."
