Find x in the given figure. answers: A) 120° B) 60° C) 72° D) 168°

Answer:

Consider the point (0,3) as point A.

Consider the point (7,0) as point B.

Plot both point on the graph.

Graph a line which passed through both the lines.

There are two conditions given to us in the question.

First condition is the we have to shade the graph below the given line.

The blue region in the graph satisfies this condition.

Second condition is that we have to shade the first and fourth quadrant, which means than the value of x is equal to or greater than zero. Red region satisfies this condition.

As the solution is represented by Both the conditions combined.  The purple area satisfies both the conditions, hence solution is given by the Purple Region

The solution is given by the Black Region.

We have two points (0,3) and (7,0)

Plot both point on the graph.  

The line passes through two points (0,3) and (7,0)  

We have two condition

Blue region satisfies this condition.

The solution is represented by Both the conditions combined.  

The Black region satisfies both the conditions.

Therefore, the solution is given by the Black Region.

Answer:

The area of the rectangle would be 20 square units.

Step-by-step explanation:

The distance between the points (-8, -2) and (-3,-2) is 5. This is the length of the rectangle.  The distance between (-3,-6) and (-3,-2) is 4. This is the width of the rectangle. To find the area, multiply the length and the width to get the 20 square units as the area.

Answer:

Area = 20

As B = -4

Where -3-1 = -4

We look at x for first measure = -8 -3 = 5

We look at y first sequence change for second measure = -B

x/y = -3-8 /-8 + B

= -3-8 = -8(-8)+B

B = -3+B = -3+1

B= -3+1 = -4

Second measure = -8-4 = 4

Therefore, using both measures in bold : the Area = 4 x 5  = 20

Answer:

[tex]1 \times 10^{10}[/tex] more pieces of mail were handled in 1995 than in 2010.

Step-by-step explanation:

We are given that in 1995, the USPS approximated that they handled  [tex]1.8 \times 10^{11}[/tex] pieces of mail and in 2010, the USPS reported that they handled [tex]1.7 \times 10^{11}[/tex]  pieces.

To find how many more pieces of mail were handled in 1995 than in 2010, we do subtraction of the pieces of mail that were handled in both the years.

Pieces of mail handled in 1995 = [tex]1.8 \times 10^{11}[/tex]

Pieces of mail handled in 2010 = [tex]1.7 \times 10^{11}[/tex]  

As it is clear that more pieces of mail were handled in 1995.

So, Pieces of mail handled in 1995 - Pieces of mail handled in 2010 = [tex](1.8 \times 10^{11}) -(1.7 \times 10^{11})[/tex]

=  [tex]10^{11} \times (1.8 -1.7)[/tex]

=  [tex]10^{11} \times 0.1[/tex] = [tex]1 \times 10^{10}[/tex]

Hence, [tex]1 \times 10^{10}[/tex] more pieces of mail were handled in 1995 than in 2010.

Answer:

x = 85 Degrees

y = 85 Degrees

Step-by-step explanation:

20 Degrees + 90 Degrees -->

90 and 20 are given => 110 Degrees

e triangle angles sum = 180 Degrees

180 - 110 = 70 Degrees

=> Vertical angles so 25 + x + 70 = 180

x = 85

x + (z) = 180 e sum of half 360

85 + z = 180

z = 95 Degrees

--> z + (y) = 180 e same as above (sum of interior angles)

95 + y = 180

y = 85

Answer:

[tex] x=\frac{8}{3}\: \: y=\frac{7}{3}[/tex]

Step-by-step explanation:

Add the two equations:

$ x+y +(2x-y)=5+3$

$\implies 3x=8$

$\implies x=\frac{8}{3}$

Use this value in the first equation:

$\frac{8}{3}+y=5$

$\implies y=\frac{15-8}{3}=\frac{7}{3}$

Answer:

x + y = 5 Equation 1

2x-y = 3 Equation 2

Add both Equations

y will be eliminated so it will be

3x = 8

x = 8/3

Substitute x into equation 1

8/3 + y = 5

y = 5 - 8/3

y= 7/3

x = 8/3 y = 7/3

Answer:

This is not an answer, just my though process:

Step-by-step explanation:

The fastest method would use all white squares:

96 white squares would take 13.7 days to complete and cost $115.20.

The cheapest method would use all blue squares:

96 blue squares would take 24 days to complete and cost $76.80.

As we can see, time is not the limiting step, the maximum of 96 squares is limiting.

An inequality equation should use the limiting step for it to be useful. Therefore, a, is most likely the answer.

Answer:

Please see attached image

Step-by-step explanation:

We start by finding the actual algebraic expression for g(x):

g(x) = f(x+1) = 4(x+1) - 2 = 4 x + 4 - 2 = 4 x + 2

Then we plot this function on the x-y plane using two or three pairs solution to the equation, like:

for  x = 0  g(x) = 2

for x = 1   g(x) = 6

for x = -1  g(x) = -2

and joining them with a line.

Answer:

4000 N

Step-by-step explanation:

this question should be in physics actually

m = 1200 kg

initial velocity = vo = 15 m/s

final velocity = vt = 0 because it stops

time needed = t = 4.5

so we can find the Force F by these step

first find deacceleration

vt = vo + at

0 = 15 + a(4.5)

15 = -4.5a

a = - 15/4.5 = - 10/3 = - 3.33 m/s²

F = m.a = 1200 . 10/3 = 4000 N

Answer:

3 (x - 5.50) = 111.75

Step-by-step explanation:

They paid $111.75 for three months,  that means they minus $5.50 every month which means a total of $16.5 for three months.

So you need use $111.75 plus the credit $16.5 for three months

111.75 + 16.5 = 128.25

Then use divide them by 3, (three months)

128.25 / 3 = 42.75

So they pay $42.75 per month before the credit.

I wish this could help you.

Answer:

[tex]A = 20,000(0.85)^t[/tex]

Step-by-step explanation:

We will use the formula for compound interest here

where [tex]A = p( 1 + r)^t[/tex]

   A=future value  for any sum

   P=present value of the sum

   r= yearly interest rate, it should be expressed in  decimal

   t=time period , it should be in years

______________________________

given in the problem

p = $20,000

r = 15% (in decimal 15/100 = 0.15)

t is the time for which equation is to be model to find future value p

since, rate is for depreciation we need to take negative value of rate as value for computer will decrease

thus

r = -0.15

using the above values in formula  [tex]A = p( 1 + r)^t[/tex]

[tex]A = p( 1 + r)^t\\A = 20,000(1 - 0.15)^t\\A = 20,000(0.85)^t[/tex]

Thus, model  equation for the value of the computer is [tex]A = 20,000(0.85)^t[/tex]

Answer:

B. x = 3

Step-by-step explanation:

You really don't need to quadratic formula for this. It would take too much time. Instead, factor out the equation:

(x -3)(x - 3) = 0

Once you found that, you should see that your roots will equal to 3.

Answer:

solution,

Rewrite x^2-6x+9 in the form a^2-2ab+b^2 where a=X and b=3.

[tex] {x}^{2} - 2(x)(3) + {3}^{2} = 0[/tex]

Use square of difference,

[tex] {(a - b)}^{2} = {a}^{2} - 2ab + {b}^{2} \\ {(x - 3)}^{2} = 0[/tex]

Take the square root of both sides

[tex]x - 3 = 0[/tex]

Add 2 to both sides,

[tex]x - 3 + 3 = 0 + 3 \\ x = 3[/tex]

hope this helps..

LET ORANGES=X

PEARS ARE 3 TIMES =3X

LET CHILDREN=Y

IF WE GIVE 5 ORANGES PER CHILD WE NEED 5Y ORANGES.SO THIS =X

X=5Y........................I

IF WE GIVE 8 PEARS PER CHILD WE NEED 8Y PERARS...THERE ARE STILL 21 PEARS LEFT OUT AFTER THIS THAT IS

8Y+21=3X....................II

SUBSTITUTING FOR X FROM EQN.I..

8Y+21=3*5Y

15Y-8Y=21

7Y=21

Y=3

X==5Y=5*3=15..

SO CHILDREN =3

ORANGES=15

PEARS=3*15=45
