The width of a triangle is represented by 5 +2y. The length is twice as long as the width. What is the perimeter of the rectangle? Select all correct expressions.

Answer:

C. 6√55

Step-by-step explanation:

The triangle given is an isosceles triangle that is divided into two equal parts by a segment.

Thus, we can apply pythagorean theorem to find x.

x = 2 × √(24² - 9²)

x = 2 × √495

x = 2 × √(9 × 55)

x = 2 × 3√55

x = 6√55

Answer:

y= -5x+8

Step-by-step explanation:

So frstt you gotta know the form

y= mx+b

y= random Y-coordinate (not useful in this situation)

m= slope

x= random X coordinate (not useful in this situation)

b= y-intercept (the first point of the line that hits the y axis)

So first lets find the slope

sure we can use the slope formula between 2 points but I just did rise over run since this is an easy graph

Rise 5 and go Left 1 so the slope is -5/1 or -5 (negative due to the run going left instead of right plus the line is negative since its falling from left to right)

The y intercept is 8 becuase its the first point where the line crosses the Y axis

ANd thats it!

Plug it in

y= -5x+8

Answer:

x = -2

Step-by-step explanation:

3x - 8  = 6x - 2

Isolate x.

3x = 6x - 2 + 8

3x - 6x = 6

-3x = 6

x = 6 ÷ -3

x = -2

Answer: 5,120

Step-by-step explanation:

Your equation is:

v(t) = 320 • 4^t

You are trying to find v(2) so:

t = 2

Plug in 2 for t:

v(2) = 320 • 4²

Solve:

v(2) = 5,120 views

Answer:

264/8 = 33

33 X 4 = 132

$132

The amount fruit seller collects would be equal to $132

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

We are given that  fruit seller has 264 oranges packed in bags, with 8 oranges in each bag. She sells each bag of oranges for $4.

264/8 = 33

Now for 33 bag of oranges are;

33 X 4 = 132

He fruit seller collects $132

Answer:

1. m = 1

2. m = 0

Step-by-step explanation:

[tex]m = \frac{y \frac{}{2} - y \frac{}{1} }{x \frac{}{2} - x \frac{}{1} } [/tex]

m = slope

To know the slope you need only 2 points of the line.

1.-

[tex]m = \frac{4 - ( - 1)}{2 - ( - 3)} \\ m = \frac{4 + 1}{2 + 3} \\ m = \frac{5}{5} \\ m = 1[/tex]

2.-

[tex]m = \frac{3 - 3}{2 - 0} \\ m = \frac{0}{2} \\ m = 0[/tex]

Answer:

the present age of the old ship is 8 years

The present age of the new ship is 4 years

Step-by-step explanation:

Let the age of the older ship be x

Let the age of newer ship be y

If the sum of ages of two ship 12years old, then;

x + y = 12 .... 1

Two years ago;

Older ship age = x - 2

New ship age = y - 2

If two years ago, the age of the older ship was three times the age of the newer ship, then;

x - 2 = 3(y-2)

x-2 = 3y - 6

x = 3y - 4 ....2

Substitute equation 2 into 1;

From 1; x+ y = 12

3y-4+y = 12

4y = 12 + 4

4y = 16

y = 4

Since x+y = 12

x = 12-y

x= 12-4

x = 8

Hence the present age of the old ship is 8 years

The present age of the new ship is 4 years

Answer:

Step-by-step explanation:

a.  the question can be factored as (x-5)(x-1) so the 2 x intercepts are 5 and 1

b. yes the function has a line of symmetry every parabola does and it is at  when x is 3

x. the function has a minimum value because the equation has x^2  which is 1x^2 1 is a positive meaning that the function opens upward which means it has a minimum value

Answer:

A)

(1, 0) and (5, 0)

B)

Yes.

The equation is x = 3.

C)

Yes.

In this case, we have a minimum.

Step-by-step explanation:

We are given the function:

[tex]f(x)=x^2-6x+5[/tex]

Since the highest degree is two, we can immediately determine this to be a quadratic.

A)

The x-intercepts of a function are whenever the function equates to 0. Hence:

[tex]0=x^2-6x+5[/tex]

We can factor:

[tex](x-1)(x-5)=0[/tex]

Zero Product Property:

[tex]x-1=0\text{ or } x-5=0[/tex]

Solving yields:

[tex]x=1 \text{ and } x=5[/tex]

So, our x-intercepts are at (1, 0) and (5, 0).

B)

Since this is a quadratic, it indeed has a line of symmetry.

Recall that the line of symmetry for a quadratic equivalent to the x-coordinate of the vertex.

In the given function, a = 1, b = -6, and c= 5.

Hence, the x-coordinate of the vertex is:

[tex]\displaystyle x=-\frac{b}{2a}=-\frac{(-6)}{2(1)}=\frac{6}{2}=3[/tex]

So, the line of symmetry is x = 3.

C)

Every parabola has a minimum/maximum value.

This depends on the sign of the leading coefficient.

If the leading coefficient is positive, then we have a minimum since our parabola will be curving upwards.

And if the leading coefficient is negative, then we have a maximum since our parabola will be curving downwards.

Since our leading coefficient here is 1, hence positive, we have a minimum value.

Answer:

  3) ? = 21

  4) ? = 6

Step-by-step explanation:

3) The given ratio is ...

  A : B = 2 : 7

You want to find ? such that ...

  2 : 7 = 6 : ?

The ratio is equivalent when both numbers are multiplied by the same value.

From your knowledge of multiplication tables, you know that 2×3 = 6. then 7×3 = ? = 21.

__

4) For this one, you need to recognize that the given number corresponds to B.

  A : B = 2 : 3

  2 : 3 = ? : 9

Again, you know that 3×3 = 9, so 3×2 = ? = 6.
