Find the rate of change from the given table.

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.

the area of one cookie slice is 7

Ste p-by-step explanation:

We know that 4 times 64 equals 256, so know we need to figure out what 64/4 is. 16. Now, 16/4, which is 4. 4 to the power of 4 equals 256.

Answer: 4

Answer:

Step-by-step explanation:

You must first know that 1 week = 7days

If Sophie practices the piano 105 minutes in 1 week, this can be expressed as;

105 minutes = 7days

to calculate the total time t that she practices for any number of days, d, we will say;

t minutes = d days.

Solving both expression;

105 minutes = 7days

t minutes = d days.

Cross multiply;

7 * t = 105 * d

7t = 105d

Divide both sides by 7;

7t/7 = 105d/7

t = 15d

Hence a proportional equation for t in terms of d that matches the context is expressed as t = 15d

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].

Answer:

The lesson activity requires students to use up to four fours and any operation to make the numbers from 0 to 100. For example, 4 + 4 + 4 + 4 = 16.

Initially, students will use the more familiar operations, +, −, ×, ÷, along with brackets to create their equations.  For example, (4 × 4 + 4) ÷ 4 = 5. Gradually, finding solutions for the remaining numbers in the list becomes more challenging. Here, it is a good opportunity to introduce some other operations to the students, including √4 = 2 and 4! = 24. In my experience, at least one student in the class will be familiar with the square root operation √n, which will make it easier to introduce. The other operation n!, known as factorial, will be less familiar to students.

n! is the product of all positive integers less than or equal to n; for example, 4! = 4 × 3 × 2 × 1 = 24, or 3! = 3 × 2 × 1 = 6

With the introduction of these two less familiar operations, the number of solutions that students can find to the initial problem increases.

[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].

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

since RT is a bisector or AC and AR=5 then RC=5

Circumcenter is equidistant from the vercices of the triangle so

AT≅BT≅CT

Answer:

Undefined.

Step-by-step explanation:

m = y2-y1 / x2-x1

m = 3 - 2 / 1 - 1

m = 1/0, which is undefined.

You can also tell because (1,2) and (1,3) is a vertical line, which means the slope is undefined.

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.

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: 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
