Answer:

5 hope this helps

Step-by-step explanation:

Answer:

11. AREA=AREA 9F RECTANGLE +AREA OF SEMICIRCLE

AREA=LW+0.5pie×r²

r=18in/2=8in

Area=18in×36in+0.5×3.14×(9in)²

Area=648in²+127.17in²

Area=775.17in²

area=775.2in²

12. Area of the shaded region=Area of rectangle-area of semicircle

r=5in/2=2.5in

=LW-0.5pie×r²

=6in×5in-0.5×3.14×(2.5in²)

Step-by-step explanation:

For this type of question, it helps to draw the rectangle and label its sides. Label the length x. We are given that the width is 5 miles less than the length, which can be represented algebraically as x-5. So, if y = width, then we have y = x-5.

We are also given that the area is 84 square miles, so how do we find the area of a rectangle? The formula is Area = length * width. Substituting in what we know, we get 84 = x(x-5). We distribute on the right hand side to get 84 = x^2-5x, which is equivalent to x^2-5x-84=0. This can be factored as (x-12)(x+7)=84. The solutions are x=12 or x=-7, but we ignore x=-7 because we cannot have negative length. Thus, the length of the rectangle is 12 miles and the width is 12-5=7 miles.

a = (v-u)/t

Step-by-step explanation:

v = u + at

subtract u from both sides

v - u = at

divide each side by t

Answer: The function that represents the inequality of the given graph is;

Option A

Graph Inequalities

From the given graph, the curve with the shaded dot shows less than or equal to because the dot indicates that the maximum input value of x is at that point.

Secondly, the curve without a shaded dot shows that the input function of x is only greater than 3.

Looking at the options, option A is right and we will prove it thus;

for y = x³ - 3

At x = 2, we see that;

y = 2³ - 3

y = 5

This corresponds with the given equation

For the second curve, for y = x² + 6;

At x = 2, we have;

y = 2² + 6

y = 4 + 6

y = 10

This corresponds with what is given and is thus correct.

This, option A is the correct answer

or,47 answer

Answer:

x+6 < 19

5x < 20

x < 8

Step-by-step explanation:

To solve this problem, you have to plug in numbers for every statement to see if it is true or not. You know that x is a number less than 4, so we can use 3 as an example.

x-2 > 2 | ❌

This can be rewritten as 3-2 > 2 (since we are plugging in 3, any number less than 4 works)

That is equal to 1 > 2, which is not correct. One is not larger than two.

x+6 < 19 | ✅

This can be rewritten as 3+6 < 19 (for the same reason as above)

That is equal to 9 < 19. 19 is greater than 9, so this is correct.

x < 2 | ❌

This can be rewritten as 3-2 > 2.

That is equal to 1 > 2, which is wrong.

5x < 20 | ✅

This can be rewritten as 5 x 3 < 20

That is equal to 15 < 20, which is correct. 15 is less than 20.

x < 8 | ✅

This can be rewritten as 3 < 8.

3 is less than 8, so this is correct.

y = 4.2

Coordinate form : (0.7, 4.2)

Step-by-step explanation:

Solve:

Plug in in 6x for y in 4x + y = 7

Plug in 0.7 for x in y = 6x

x = 0.7
y = 4.2

Coordinate form : (0.7, 4.2)

-Chetan K

Answer:

x = 7/10 (fraction)

Step-by-step explanation:

Given that y = 6x, we can substitute it for y

That makes your equation:

4x + 6x = 7

Now, all we need to do is solve for x:

Step 1: Add similar elements:

4x+6x=10x, which gives you 10x=7

Divide next:

10x/10=7/10 (10/10 = 0 and 7/10 = 7/10)

x= 7/10

Step-by-step explanation:

Re-order terms so constants are on the left

(5k-10)  · -9

-9(5k-10)

Distribute

-9(5k-10)  

[-9 · 5k = -45k]                              Negative + Positive = Negative

[-9 · -10 = 90]                                Negative + Negative = Positive

-45k+90

Hence, -45k+90  is the Answer.

Answer:

18 and 24.

Step-by-step explanation:

x + (x + 6) = 42

x + x + 6 - 6 = 42 - 6

x + x = 36

2x = 36

2x/2 = 36/2

x = 18

42 - 18 = 24 The numbers are 18 and 24.

The required two numbers are 18 and 24 and number is 6 more than the the smaller number.

Given, that one number is 6 more than other.

Let the number be x.

Let the other number be x + 6 .

Rewriting in form of equation, that sum of two numbers is 42.

x + (x + 6) = 42

Subtract 6 from both sides.

x + x + 6 - 6 = 42 - 6

Combine like terms,

x + x = 36

2x = 36

Divide by 2 on both sides,

2x/2 = 36/2

x = 18

Thus one number is 18.

The other number is 6 more than 18,

18 + 6 = 24

Thus the two numbers are 18 and 24.

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

30 - 36 = -33

-3 = -33

The equation does not satisfy the ordered pair

d)

The equation is

8m = −23 + 21n

Substituting the values , we get

8 x 5 = -23 + 21 x 3

40 = -23 + 63

40 = 40

The equation satisfies for the ordered pair

e)

The equation is

4m − 3n = 11

Substituting the values , we get

4 x 5 - 3 x 3 = 11

20 - 9 = 11

11 = 11

The equation satisfies for the ordered pair

f)

The equation is

2m + 5 = 5n

Substituting the values , we get

2 x 5 + 5 = 5 x 3

10 + 5 = 15

15 = 15

The equation satisfies for the ordered pair

g)

The equation is

9m + 4n = 5

Substituting the values , we get

9 x 5 + 4 x 3 = 5

45 + 12 = 5

57 = 5

The equation does not satisfy the ordered pair

h)

The equation is

3m = 9 + 6n

Substituting the values , we get

3 x 5 = 9 + 6 x 3

15 = 9 + 18
