Answer:

110cm²

Step-by-step explanation:

*Diagram is ALSO not accurately drawn

18cm-6cm-5cm=7cm

11cm-9cm=2cm

Area:

11cm×6cm=66cm²

7cm×2cm=14cm²

6cm×5cm=30cm²

Area of the shape:

66cm²+14cm²+30cm²=110cm²

Answer:

Not a quadratic function.

Step-by-step explanation:

A function is a relation wherein each input or x-value corresponds exactly to an output or y-value.  In other words, a relation is a function if there are no repeating x-values.  

A way to determine whether a given graph represents a function is to perform the Vertical Line Test.  Using the Vertical Line Test, we must draw vertical lines across the graph.  If each of the vertical lines drawn intersects the graph at exactly one point, then the relation is a function.  

⇒  The attached screenshot shows that the given graph fails the Vertical Line Test, as each vertical line drawn intersects the graph more than once. This means that those x-values correspond to more than one y-value. Specifically, x = 1 corresponds to the following y-values: y = -1 and y = 1.   Hence, the given horizontal parabola is not a quadratic function.

The given graph represents a horizontal (or sideways) parabola.

The vertex form of the horizontal parabola is: x = a(y - k)² + h.  

where:

a = Determines the direction of the graph's opening.

y = k is the horizontal axis of symmetry

k = determines the vertical translation of the graph

h = determines the horizontal translation of the graph

The vertex of the given graph occurs at the point of origin, (0, 0).

Let's use one of the given points on the graph, (1, 1), and substitute these values into the vertex form to solve for a :

x = a(y - k)² + h

1 = a(1 - 0)² + 0

1 = a( 1 )²

1 = a

Equation of the given horizontal parabola in vertex form:  

      ⇒     x = (y - 0)² + 0  or  x = y²

It is evident that in the vertex form of a horizontal parabola, the variable, y, is squared.

                          x = 1 has two y-values: y = -1, and y = 1.

                           x = 4 has two y-values: y = -2, and y = 2.

Thus, by definition of function, the given horizontal parabola is not a quadratic function, as it fails the vertical line test.

Answer:

x = 4

y = 2

Step-by-step explanation:

1) y = 5x - 6

2) y = 4x - 2

sub 1 into 2

5x - 6 = 4x - 2

5x - 4x = 6 - 2

x = 4 ---> (3)

sub 3 into 2

y = (4 * 1) - 2

y = 4 - 2

y = 2

Answer:

Step-by-step explanation:

Since they both equal y, they are both equivinlent

Step-by-step explanation:

r=10

π=3

[tex]a = \pi{r}^{2} [/tex]

[tex]a = (3) {(10)}^{2} [/tex]

[tex]a = 300[/tex]

Answer:

A = 300 ft^2

Step-by-step explanation:

First we need to  find the radius

r = 1/2 d

The diameter is 20

r = 1/2(20) = 10

A =pi r^2

We are using 3 for pi

A = 3( 10)^2

A = 3 * 100

A = 300 ft^2

Step-by-step explanation:

[tex](3r + 4) + (8r - 2) = 90[/tex]

[tex]3r + 4 + 8r - 2= 90[/tex]

[tex]11r = 88[/tex]

[tex]r = \frac{88}{11} \\ [/tex]

[tex]r = 8[/tex]

5(4x + 3y) = $7.43 × 5

or, 20x + 15y = $37.15 ...(3)

4(5x + 2y) = $7.03 × 4

or, 20x + 8y = $28.12 ...(4)

20x + 15y-(20x + 8y) = $37.15 - $28.12

or, 7y = $9.03

or, y = $1.29

or, 4x + 3($1.29) = $7.43

or, 4x + $3.87 = $7.43

or, 4x = $7.43 - $3.87

or, 4x = $3.56

or, x = $0.89

Answer:

A) $0.89

I feel as though there is a formula for this but I cannot remember at the moment so I am gonna do it the long way!

2(-8) + 6(7) =26

-16 + 42 + 26

26 = 26 Yes

____________

2(-1) + 6(4) =26

-2 + 24 =26

22 = 26 No

____________

2(2) + 6(5) =26

4+30 = 26

34 =26 No

____________

2(4) + 6(3) =26

8+18

26 = 26 Yes

____________

2(16) +6(-1) =26

Step-by-step explanation:

The number of calories in 14 brownies is 233 calories.

In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.

here, we have,

given that,

A nutrition company is marketing a low-calorie snack brownie. A serving size of the snack is 3 brownies and has a total of 50 calories.

The first step is to determine the average calorie in 1 brownie.

Average calorie = 50 calories / 3 = 16.667 calories

In order to determine the number of calories in 14 brownies, multiply the average calorie by 14 brownies.

Total calories = 16.67 x 14 = 233 calories

Hence, The number of calories in 14 brownies is 233 calories.

Answer:

You would pay $30.6, and the discount would be $3.4

Step-by-step explanation:

Because it is a 10% discount, you will only have to pay 90%. So: 0.9*34=30.6

Another way to solve it would be to calculate 10%, which would be 3.4, so 34-3.4=30.6

Answer:

y = - 2x - 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

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

with (x₁, y₁ ) = (- 4, 4) and (x₂, y₂ ) = (2, - 8) ← 2 points on the line

m = [tex]\frac{-8-4}{2-(-4)}[/tex] = [tex]\frac{-12}{2+4}[/tex] = [tex]\frac{-12}{6}[/tex] = - 2

The line crosses the y- axis at (0, - 4 ) ⇒ c = - 4

y = - 2x - 4 ← equation of line

Answer:

f(-9) = 135

Step-by-step explanation:

Replace x with -9, and evaluate the expression.

f(x) = 2x² + 3x

f(-9) = 2(-9)² + 3(-9)

f(-9) = 2(81) - 27

f(-9) = 162 - 27
