Answer:

Step-by-step explanation:

Answer:

x=9

y=6

Step-by-step explanation:

x+y=15 .............(i)

x-y=3...........(ii)

Subtracting equation (ii) from equation (i)

or,  x+y -(x-y)=15-3

or,  x+y-x+y=12

or,  2y=12

or,  y=12/2

∴y=6

Now,

       Putting the value of y on equation (i),

or,  x+6=15

or,  x=15-6

∴x=9

C 315

Step-by-step explanation:

(12 + 30) * 15/2 = 315

The area of the trapezoidal patio is 252 ft².

A trapezoid is a polygon that has only one pair of parallel sides. These parallel sides are also called parallel bases of trapezoid. The other two sides of trapezoids are non-parallel and called legs of trapezoids.

Given that, Mr. Kramer's patio is in the shape of a trapezoid, we need to find its area,

So, the area of the trapezoid is = sum of the parallel sides × height/2

= 12 + 30 × 12/2

= 42 × 6

= 252

Hence the area of the trapezoidal patio is 252 ft².

Answer:

4180 AED

Step-by-step explanation:

Given data

Principal= 4000

Time= 3 years

Rate= 1.5%

The compound interest expression is given as

A= P(1+r)^t

substitute

A=4000(1+0.015)^3

A= 4000(1.015)^3

A= 4000*1.045

A= 4180

Answer:

[tex]y=\frac{0}{-1} -4[/tex]

Step-by-step explanation:

first, you have to find the slope, and to do that you use this equation [tex]\frac{y2-y1}{x2-x1}[/tex]

     so, now to insert your points (0,-4), (-1,4)

                                                      (x1,y1)  (x2,y2)

[tex]\frac{4-4}{-1-0} = \frac{0}{-1}[/tex]

now that you have the slope you can find the y-intercept of the slope-intercept form by looking at your first point (0,-4) and get -4

- if you were to look at this point on a graph it would be on the y-axis therefore, -4 is the y-intercept [if you don't have a point like this one then you can look at a graph with one of your points and make a slope until you are on the y-axis :)]

therefore, the slope-intercept form is y=[tex]\frac{0}{-1}[/tex] -4

[ps, your slope is a zero slope :)]

Answer:

y = - 8x - 4

Step-by-step explanation:

y = mx + b

"m" is slope, "b" is y-intercept.

( [tex]x_{1}[/tex] , [tex]y_{1}[/tex] )

( [tex]x_{2}[/tex] , [tex]y_{2}[/tex] )

m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

~~~~~~~~~~~~~~~

(0, - 4) are coordinates of y-intercept.

( - 1, 4)

m = [tex]\frac{4 + 4}{-1-0}[/tex] = - 8

y = - 8x - 4

Answer:

8 38/45 inches

Step-by-step explanation:

A regular size chocolate bar is 5 and 4/9 inches long. If the king size bar is 3 and 2/5 inches longer, what is the length of the king size bar?

Let us represent:

Length of regular size chocolate bar = x

Length of king size chocolate bar = y

A regular size chocolate bar is 5 and 4/9 inches long.

x = 5 4/9 inches

If the king size bar is 3 and 2/5 inches longer,

Hence:

y = x + 3 2/5 inches

The length of the king size bar is calculated as:

5 4/9 inches + 3 2/5 inches

(5 + 3) + ( 4/9 + 2/5)

Lowest common denominator = 45

8 + (20 + 18/45)

8 38/45 inches

Answer:

[tex] - 32[/tex]

Step-by-step explanation:

1) Simplify

[tex] \sqrt{32} \: to \: 4 \sqrt{2} [/tex]

[tex] - 8 \sqrt{2} \times \frac{1}{2} \times 4 \sqrt{2} [/tex]

2) Use this formula: a/b × c/d = ac/bd.

[tex] - \frac{8 \sqrt{2} \times 1 \times 4 \sqrt{2} }{2} [/tex]

3) Simplify.

[tex] - \frac{32 \sqrt{2 \sqrt{2} } }{2} [/tex]

4)

[tex]simplify \: 32 \sqrt{2 } \sqrt{2} \: to \: 32 \sqrt{4} [/tex]

5) Since 2 × 2 = 4, the square root of 4 is 2.

[tex] - \frac{32 \times 2}{2} [/tex]

6) Simplify 32 × 2 to 64.

[tex] - \frac{64}{2} [/tex]

7) Simplify 64/2 to 32.

[tex] - 32[/tex]

Therefor, the answer is option three -32

Answer:

5/6

Step-by-step explanation:

There is a 1 out of 2 chance that you will roll tails, so the probability is 1/2.

A number less than three is a 2 and 1, so the probability is 2/6.

Add 1/2 + 2/6. (Change 1/2 to 3/6 so you can add.)

3/6 + 2/6 = 5/6

I hope this is correct and helps you!

Answer:

14/5

Step-by-step explanation:

Given data

We have the function

f(x)= (3x+2)/5

We want to find  f(4)

Hence, let us place x= 4 in the function

f(4)= (3(4)+2)/5

f(4)= (12+2)/5

f(4)= (14)/5

f(4)=14/5

Hence f(4)=  14/5
