Answer: No

Step-by-step explanation:

The c kind of cut off, but you can use slopes to figure it out. The rule for a perpendicular slope is the opposite reciprocal. Assuming that C is the right angle, since right triangles typically work that way, we can figure out the slopes for ac and bc. The slopes are not reciprocals:

AC= -5/2

BC=  -1/3

This isn't a right triangle because the lines are not perpendicular.

The width of a rectangle is 3 cm less than twice its length. If the perimeter of the
rectangle is 18 cm, find its dimensions.

Answers

Answer:

length=4

Width=2×4-3=5

Step-by-step explanation:

Let length =X

Width =2x-3

Perimeter=18

2(length+width)=18

2(X+2x-3)=18

3x-3=9

3x=12

X=12/3

X=4

So length=4

Width=2×4-3=5

Answer:

[tex] \huge{ \boxed{ \bold{ \sf{Length \: = \: 4 \: cm}}}}[/tex]

[tex] \huge{ \boxed{ \bold{ \sf{Width = 5 \: cm}}}}[/tex]

▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁

Question :

The width of a rectangle is 3 cm less than twice its length. If the perimeter of the rectangle is 18 cm, find its dimensions.

Step - by - step explanation :

✒ First, Let length of a rectangle be ' L '.

✑ Given :

Width of a rectangle = 3 cm less than twice its length ( i.e W = 2L - 3 )Perimeter of a rectangle ( P ) = 18 cm

Finding value of length of a rectangle :

[tex] \boxed{ \sf{Perimeter \: of \: a \: rectangle = 2(L + W)}}[/tex]

Plug the values and solve for L

➺ [tex] \sf{18 = 2(L+ 2L - 3)}[/tex]

➺ [tex] \sf{18 = 2(3L - 3)}[/tex] { Add : 2L and L )

➺ [tex] \sf{18 = 6L - 6}[/tex] { Distribute 2 through the parentheses )

➺ [tex] \sf{6L - 6 = 18}[/tex] { Swipe the sides of the equation }

➺ [tex] \sf{6L = 18 + 6}[/tex] { Move 6 to right hand side and change it's sign )

➺ [tex] \sf{6L = 24}[/tex] { Add the numbers : 18 and 6 }

➺ [tex] \sf{ \frac{6L}{6} = \frac{24}{6}} [/tex] { Divide both sides by 6 }

➺ [tex] \boxed{ \sf{length \: ( \: L\: ) \: = \: 4 \: cm}}[/tex]

☞ Now , Evaluating 2L - 3 when L = 4 cm in order to find the value of width of a rectangle : [tex] \sf{2l - 3}[/tex]

➺ [tex] \sf{2 \times 4 - 3}[/tex] { Plug the value of length }

➺ [tex] \sf{8 - 3}[/tex] { Multiply 2 by 4 }

➺ [tex] \boxed{ \sf{Width \: ( \: W \: ) \: = \: 5 \: cm}}[/tex]

Hence ,

Length of a rectangle ( L ) = 4 cmWidth of a rectangle ( W ) = 5 cm

Answers

Answer:

[tex]\mathrm{Factor}\:x^2+5x+6:\quad \left(x+2\right)\left(x+3\right)[/tex]

Step-by-step explanation:

Let us assume the trinomial of the form [tex]x^2+bx+c[/tex]

[tex]x^2+5x+6[/tex]

Break the expression into the groups

[tex]=\left(x^2+2x\right)+\left(3x+6\right)[/tex]

Factor out 'x' from [tex]x^2+2x[/tex]

i.e.

[tex]\:x^2+2x=x\left(x+2\right)[/tex]

Factor out '3' from 3x+6

i.e.

3x+6 = 3(x+2)

so the expression becomes

greatest common factor of 24, 36, and 50

Answers

Answer:

The greatest common factor of 24, 36, and 50 is 2.

Step-by-step explanation:

Factors of 24 are 1, 2, 3, 4, 6, 8, 12, 24

Factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, 36

Factors of 50 are 1, 2, 5, 10, 25, 50

Therefore the GCF is 2.

We can see that 2 is the only common factor, hence the greatest common factor of 24, 36, and 50 is 2

For us to get the greatest common factor of 24, 36, and 50, we need to get their individual factor first as shown:

24 = 2 * 12

36 = 2 * 18

50 = 2 * 25

From all the factors, we can see that 2 is the only common factor, hence the greatest common factor of 24, 36, and 50 is 2

A company has a $150 budget to provide lunch for its 20 employees. The options are to provide either roast beef sandwiches, which cost $5 apiece, or tuna sandwiches, which also cost $5 apiece. The company also wants to use the entire budget. Suppose r represents the number of roast beef sandwiches it provides and t represents the number of tuna sandwiches. Which statement is correct?
The company can provide lunch for all 20 employees and use the entire budget because there is a solution to the system of equations r minus t = 20 and 5 r + 5 t = 150.
The company can provide lunch for all 20 employees and use the entire budget because there is a solution to the system of equations r + t = 20 and 5 r + 5 t = 150.
The company cannot provide lunch for all 20 employees and use the entire budget because there is no solution to the system of equations r minus t = 20 and 5 r + 5 t = 150.
The company cannot provide lunch for all 20 employees and use the entire budget because there is no solution to the system of equations r + t = 20 and 5 r + 5 t = 150.

Answers

Answer:

D.) The company cannot provide lunch for all 20 employees and use the entire budget because there is no solution to the system of equations r+t=20 and 5r+5t=150

Step-by-step explanation:

The given information says that the total amount of lunch bought should equal $150 when both options cost $5:

[tex]5r+5t=150[/tex]

It also says that the food should feed all 20 employees:

[tex]r+t=20[/tex]

This is now a system. Solve by substitution.

Solve the second equation for r. Use inverse operations to isolate the variable by subtracting t from both sides:

[tex]r+t-t=20-t\\\\r=20-t[/tex]

Now insert this value of r into the first equation:

[tex]5(20-t)+5t=150[/tex]

Simplify the equation. Use the distributive property:

[tex]5(20)+5(-t)+5t=150\\\\100-5t+5t=150[/tex]

Cancel the terms:

[tex]100\neq 150[/tex]

100 does not equal 150, so there is no solution to the system.

Determine whether a quadratic model exists for each set of values. If so, write the model.
f(-2)=16, f(0)=0, f(1)=4

Answers

Answer:

[tex]f(x)=4x^2[/tex]

Step-by-step explanation:

Quadratic Model

The quadratic function can be expressed in the form:

[tex]f(x)=ax^2+bx+c[/tex]

Where a,b, and c are constants to be determined using the points through which the function passes.

We have the points (-2,16) (0,0) (1,4). To find the values of a,b,c we just substitute the values of x and y and solve the system of equations.

Point (0,0):

[tex]f(0)=a*0^2+b*0+c=0[/tex]

It follows that

c=0

Point (-2,16):

[tex]f(0)=a*(-2)^2+b*(-2)+c=16[/tex]

Operating:

[tex]a*(4)+b*(-2)+c=16[/tex]

Since c=0:

[tex]4a-2b=16[/tex]

Divide by 2:

[tex]2a-b=8\qquad\qquad [1][/tex]

Point (1,4):

[tex]f(1)=a*(1)^2+b*(1)+c=4[/tex]

[tex]a*(1)+b*(1)+c=4[/tex]

Since c=0:

[tex]a+b=4\qquad\qquad [2][/tex]

Adding [1] + [2]:

2a+a=12

3a=12

a=12/3=4

a=4

From [2]

b=4-a

b=4-4=0

b=0

The model is:
