Answer:

See below.

Step-by-step explanation:

[tex]h(x)=-1/2(x - 4)^2 + 3[/tex]

The domain is all real numbers.

The range is all real numbers [tex]\leq 3[/tex].

The domain of the function will be all real numbers and the range of the function will be (-∞, 3].

Let the point (h, k) be the vertex of the parabola and a be the leading coefficient. Then the equation of the parabola will be given as,

y = a(x - h)² + k

The domain means all the possible values of x and the range means all the possible values of y.

The equation of the parabola is given below.

h(x) = – 1/2(x – 4)² + 3

The vertex of the parabola is at (4, 3). The parabola is a downward parabola.

The domain of the function will be all real numbers and the range of the function will be (-∞, 3].

Answer: see explanation

Step-by-step explanation: To determine which ordered pairs satisfy the equation substitute the x coordinate of the point into the right side and if the value obtained equals the y coordinate of the point then it satisfies the equation

(- 1, - 1)

x = - 1 : y = - 4 + 3 = - 1 ⇒ (- 1, - 1) satisfies the equation

(2, 11)

x = 2 : y = 8 + 3 = 11 ⇒ (2, 11) satisfies the equation

(4, 7)

x = 4 : y = 16 + 3 = 19 ≠ 7 ⇒ (4, 7) does not satisfy the equation

(7, 1)

x = 7 : y = 28 + 3 = 31 ≠ 1 ⇒ (7, 1) does not satisfy the equation

Answer: below(=

Step-by-step explanation: Given that,

dimensions of wall = 8.3ft by 7.5ft

height of wall = 8.3

width of wall = 7.5

there are total 3 walls in a bedroom to be painted blue.

Formula to calculate area of one wall

Height x Width

Formula to calculate area of four walls

3 (Height x Width)

= 3( 8.3ft x 7.5ft)

= 3 (62.25 ft²)

= 186.75 ft²

So area Alyssa will paint = 186.75 ft²

The expression equivalent to [tex]5x\sqrt{28x^{5} } + 8x^{3} \sqrt{7x}[/tex]  is  [tex]18x^{3}\sqrt{7x}[/tex].

In order to simplify an expression, multiple processes must be used to reduce it to a simpler form.

[tex]\sqrt[n]{ab} =\sqrt[n]{a} .\sqrt[n]{b}[/tex]

= [tex]5x\sqrt{28x^{5} } + 8x^{3} \sqrt{7x}[/tex]

= [tex]5x\sqrt{4*7x^{5} } + 8x^{3} \sqrt{7x}[/tex]

= [tex]5x\sqrt{2^{2} *7x^{4}x } + 8x^{3} \sqrt{7x}[/tex]

Apply the simplification formula

= [tex]5x\sqrt{2^{2}} \sqrt{x^{4} } \sqrt{7x} + 8x^{3} \sqrt{7x}[/tex]

= [tex]5x*2x^{2} \sqrt{7x} + 8x^{3} \sqrt{7x}[/tex]

Further solve,

= [tex]10x^{3} \sqrt{7x} + 8x^{3} \sqrt{7x}[/tex]

= [tex]18x^{3} \sqrt{7x}[/tex]

The expression equivalent to [tex]5x\sqrt{28x^{5} } + 8x^{3} \sqrt{7x}[/tex]  is  [tex]18x^{3}\sqrt{7x}[/tex].

Hi there!

[tex]\large\boxed{\left \{ {{y=3x + 1} \atop {y = 3x - 1}} \right}[/tex]

From the graph, we can see that both lines are parallel. We can determine the slope of one line to find the slope of the other.

Use the slope formula to determine the slope of a line. In this case, I am using the blue line as a reference:

[tex]\text{Slope } = \frac{ y_2 - y_1 } { x_2 - x_1 }[/tex]

[tex]m = \frac{ 3 - 1 } { 1 - 0 } = 3[/tex]

The slope of both lines is 3.

Let's find the equation of the blue line by finding its y-intercept to solve for the "b" value in the equation y= mx + b:

y-intercept is when x = 0, or at (0, 1). Therefore:

Blue line equation: y = 3x + 1

The red line intersects the y-axis at (0, -1), therefore:

Red line equation: y = 3x - 1

The systems of equations is:

y = 3x + 1

y = 3x - 1

Answer:

y = 2x + 1

y= 2x - 1

Step-by-step explanation:

I just took the test and got it correct :)

Answer:

y=5x+20

Step-by-step explanation:

The slope equation is usually in the form

y= mx+b

Where "y" is intercept

m= slope

b= constant= 20$ start up fee

Then writing the equation of slope for the question we have y=5x+20 which represent the slope equation.

Answer: One hosta= $8

One shrub = $10

Step-by-step explanation:

Let the cost of one hostas be h

Let th cost of one shrub be s.

The question can be rewritten into am equation as:

2h + 7s = 86 .......... equation i

8h + 4s = 104 ........ equation ii

Multiply equation i by 8

Multiply equation ii by 2

16h + 56s = 688 ...... equation iii

16h + 8s = 208 ........ equation iv

Subtract equation iv from iii

48s = 480

s = 480/48

s = 10

One shrub cost $10

Put the value of one shrub into equation ii

8h + 4s = 104

8h + 4(10) = 104

8h + 40 = 104

8h = 104 - 40

8h = 64

h = 64/8

h = $8

One hostas cost $8

Answer:

The second statement is the contrapositive of the first.

Step-by-step explanation:

We know that x → y is a conditional statement read as 'if x then q'.

The converse EXCHANGES the hypothesis and conclusion such as:

y → x

The 'contrapositive' statement basically NEGATES the converse of the conditional such as:

¬y → ¬x

Coming back towards the question,

Given

x ⇒ y

¬y ⇒ ¬x

Therefore, the second statement is the contrapositive of the first.
