Solve for x.

​4(5x−20)=−20​

Enter your answer in the box.

x =?

Answers

Answer 1

Answer:

4(5x-20)=-20 should be x=3

Answer 2

Answer:

x = 3

Step-by-step explanation:

4(5x−20)=−20 | Given

20x - 80 = -20 | Distribute the number on the outside (multiply all numbers on the inside by the number on the outside, 4×5x and 4×-20)

20x = 60 | Add 80 to both sides (do the opposite operation, if its a negative number add it to both sides)

x = 3 | Divide both sides by 20x (20x turns into x and 60 turns into 3 via 60÷20)

Step-by-step explanation:

In a parallelogram, opposite sides are congruent and therefore have the same length. Thus, [tex]ST=RV=3[/tex] and [tex]VT=RS=10[/tex].

Similarly, opposite angles in a parallelogram are congruent and therefore have the same measure. Thus, [tex]m[/tex]∠[tex]V=m[/tex]∠[tex]S=48[/tex]° and [tex]m[/tex]∠[tex]T=m[/tex]∠[tex]R=132[/tex]°. Hope this helps!

Answers

Answer:

A. 6 feet

B. 38 feet of fencing total

Step-by-step explanation:

a. We are given 78 square feet as the total area that the fence encloses. Given this, we can use the A=l*w to solve for the side lengths.

A=l*w

Plug in known variables and simplify...

Step 1: Subtract 78 from both sides.

x^2+7x−78=78−78

x^2+7x−78=0

Step 2: Factor left side of equation.

(x−6)(x+13)=0

Step 3: Set factors equal to 0.

x−6=0 or x+13=0

x=6 or x=−13

For this case we will need to use the positive value.

so to check the answer, we can plug in 6 for x and check if it will equal 78.

(6+7)(6)

13*6

78

b. now given the value of x, we need to solve for the total amount of fencing by finding the perimeter.

We already know that one side is 6+7 or 13, and the other side is 6, so to find perimeter we use the formula 2l+2w

and solve...

2*13+2*6

26+12

A dolphin jumps out of the water with an initial velocity of 20 feet per
second (assume its starting height is O feet). Use the vertical motion
model, h = - 16t2 + vt +8, where v is the initial velocity in feet per
second and s is the height in feet, to calculate the amount of time the
dolphin is in the air before it hits the water again. Round your answer
to the nearest tenth if necessary.
Time in air: seconds

Answers

Answer:

1.6 Seconds

Step-by-step explanation:

The equation would be h(t)=-16t^2+20t+8 since 20 is the velocity, and once you input that onto a graph the answer of when it hits the ground is 1.569 seconds, so rounded is 1.6 seconds.

The Slope Is 12

Step-by-step explanation:

Below are the steps to follow to find the slope of any line.

First you need to pick two points. I chose (2,24) and (4,48). (It does not mater what points you chose.)

Now follow the equation

Slope (m) = ΔY/ΔX

ΔY = 48 – 24 = 24

ΔX = 4 – 2 = 2

24/2 = 12

Then no mater what points you chose, 12 should be your final answer

The exact perimeter of the quadrilateral ABCD plotted is 5 + √85 + 2√65.

What is the distance between two points ( p,q) and (x,y)?

The shortest distance (length of the straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:

[tex]D = \sqrt{(x-p)^2 + (y-q)^2} \: \rm units.[/tex]

The perimeter of the quadrilateral ABCD is plotted. These are the points:

A(-5,-2)

B(1,5)

C(5,-2)

D(2,-6)

The distance of AB

[tex]D = \sqrt{(x-p)^2 + (y-q)^2} \: \rm units.\\\\D = \sqrt{(1-(-5))^2 + (5-(-2))^2} \: \rm units.\\\\D = \sqrt{85}[/tex]

The distance of BC

[tex]D = \sqrt{(x-p)^2 + (y-q)^2} \: \rm units.\\\\D = \sqrt{(5-(1))^2 + (-2-(5))^2} \: \rm units.\\\\D = \sqrt{65}[/tex]

The distance of CD

[tex]D = \sqrt{(x-p)^2 + (y-q)^2} \: \rm units.\\\\D = \sqrt{(2-(5))^2 + (-6-(-2))^2} \: \rm units.\\\\D = \sqrt{65}[/tex]

The distance of AD

[tex]D = \sqrt{(x-p)^2 + (y-q)^2} \: \rm units.\\\\D = \sqrt{(2-(-5))^2 + (-6-(-2))^2} \: \rm units.\\\\D = 5[/tex]

Therefore, The perimeter of the quadrilateral ABCD is 5 + √85 + 2√65.

Find the value of r so the line that passes through each pair of points has the given slope.
(1, r), (7, 5), m = 2/3

Answers

Answer:

r = 1

Step-by-step explanation:

slope = change in y / change in x, so:

change in y / change in x  = 2/3

5 - r / 7 - 1 = 2/3

5 - r / 6 = 2/3

[tex]\frac{5-r}{6}=\frac{2}{3}[/tex]

now solve this equation.

first, multiply both sides by 6 to get rid of the fraction:

[tex]5 - r = 4[/tex]

subtract 5 from both sides

[tex]-r=-1[/tex]

multiply both sides by -1

[tex]r=1[/tex]

Solve the equation

My steps:

First thing we do is: Rearrange terms

15−4x=2(3x+1)−4x+15=2(3x+1)

Second thing we do is: Distribute

−4x+15=2(3+1)−4x+15=6x+2

Third thing we do is : Subtract  15 from both sides of the equation

−4x+15=6x+2−4x+15−15=6x+2−15

Then you carry on and find solution:

x=13/10
