Answer:

2(x+4) + 2(2x-7) = 42 ( If this is wrong simplify this)

Step-by-step explanation:

The formula for perimeter is (2 x length) + (2 x width), so our equation would be 2(x+4) + 2(2x-7) = 42

Answer:

The answer is below

Step-by-step explanation:

From the image of the leaning tower of Pisa, we can see that it passes through the point (7.75, 0) and (10.75, 42).

a) The equation of a line in slope intercept form is given by y = mx + b, where m is the slope and b is the intercept. Also, the equation of line passing through

[tex](x_1,y_1)\ and\ (x_2,y_2)\ is:\\\\y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)[/tex]

Hence since it passes through  (7.75, 0) and (10.75, 42), the equation is:

[tex]y-0=\frac{42-0}{10.75-7.75} (x-7.75)\\\\y=14(x-7.75)\\\\y=14x-108.5[/tex]

b) When the tower is 56 meters tall, i.e. y = 56, we need to find the value of x:

y = 14x - 108.5

56 = 14x - 108.5

56 + 108.5 = 14x

164.5=14x

x = 164.5/14

x = 11.75

When the tower is 56 meters tall, the top of the tower is 11.75 m off center

Answer: They should be blocked by activity level so the subjects are as similar as possible.

Step-by-step explanation:

Blocking is used to account for suspected differences in experimental units or subjects. In this case, the study wanted to take into account the difference in activity levels, which can affect the diaper's capacity as described in the paragraph.

Answer:

function is a parabola, with a lowest point of -4

Step-by-step explanation:

g(x)=x^-4

g(-3)= -3^2-4 = 9-4 = 5

g(-2)= -2^2-4 = 4-4 = 0

g(-1)= -1^2-4 = 1-4 = -3

g(0)= 0^2-4 = 0-4 = -4

g(1)= 1^2-4 = 1-4 = -3

g(2)= 2^2-4 = 4-4 = 0

g(3)= 3^2-4 = 9-4 = 5

Answer:

remainder = 0

Step-by-step explanation:

Using the remainder theorem

If f(x) is divided by (x - h) then the remainder is f(h)

Here f(x) = x³ - x² - 17x - 15 and h = 5 , thus

f(5) = 5³ - 5² - 17(5) - 15 = 125 - 25 - 85 - 15 = 0 ← remainder

Since remainder is zero then (x - 5) is a factor of f(x)

Answer:

k = 9

Step-by-step explanation:

For this, we can factor the top expression to look like the bottom expression.

So, first we have to find the gcf of 18 and [tex]x^{2}[/tex] and add up to 11x.

18[tex]x^{2}[/tex]            11x

1 and 18       19   - No

2 and 9       11    - Yes

3 and 6       9    - No

So, the numbers are 2 and 9. The expression should now look like this:

[tex]x^{2}[/tex] + 2x + 9x + 18

Now, undistribute the terms.

x(x + 2) + 9(x + 2)

(x+2)(x+9)

This matches up with the bottom expression.

The value of k is 9.

Answer:

Kindly check explanation

Step-by-step explanation:

Given that:

Cost per ticket = $3.25

Number of ride tickets purchased (x) = 8

Total amount spent at the fair (y) = $39.50

Henry's spending was only on ticket rides and fair admission

a) Find the cost of admission to the fair. Explain how you found the cost of admission.

Total spending = amount spent on ticket rides + cost of admission to fair

$39.50 = 8(3.25) + cost of admission

39.50 = 26 + cost of admission

Cost of admission = (39.50 - 26) = $13.50

(b) Write a linear equation that can be used to determine the cost for anyone who pays for ride tickets and fair admission.

Since cost of admission is the same for everyone :

Total cost = 3.25x + 13.50

y = 3.25x + 13.50

(c) Explain what the coefficient on x and the constant of your linear equation represent.

3.25 = cost per ride ticket

13.50 = cost of admission to fair

Answer:

x must be a negative to cancel out the negative sign and must be greater than 15 unless it is supposed to equal 5 then a is correct

Answer:

A isn't parallel but B is

Step-by-step explanation:

I believe A isn't parallel because it's supposed to have the same number but they're one off from each other

B is parallel because when you add the numbers they equal 180 and since they're opposite they'd have to equal 180 in order to be parallel

I hope this made sense :) if it didn't I can try to explain it again

Answer:

5:  a) No  b)Yes

Step-by-step explanation:

5a. You can know by the alternate interior angle converse thm.

The theorem says that if two interior alternate angle are the same then the lines are parallel.

5b.  You can know by the consecutive interior angles thm and the DLD thm.

First use the DLD thm to find the interior angles then use the connsectutive interior angles thm.

Answer:

the slope should be 4/2

Step-by-step explanation:

Answer:

4

Step-by-step explanation:

Slope (m) =  

ΔY

ΔX

=  

4

1

= 4

θ =  

arctan( ΔY )

ΔX

= 75.963756532074°

ΔX = 4 – 2 = 2

ΔY = 16 – 8 = 8

Distance (d) = √ΔX2 + ΔY2 = √68 = 8.2462112512353

Equation of the line:

y = 4x

When x=0, y = 0

When y=0, x = 0
