Answer 1

Answer:

[tex]x = 1[/tex]

[tex]y = -2[/tex]

Step-by-step explanation:

Given

[tex]2x - 3y = 8[/tex]

[tex]4x + 3y =-2[/tex]

Required

x and y

Add both equations to eliminate y

[tex]2x + 4x - 3y + 3y = 8 - 2[/tex]

[tex]6x = 6[/tex]

Divide both sides by 6

[tex]x = 1[/tex]

Substitute [tex]x = 1[/tex] in the first equation

[tex]2x - 3y = 8[/tex]

[tex]2 * 1 - 3y = 8[/tex]

[tex]2 - 3y = 8[/tex]

[tex]-3y = 8 - 2[/tex]

[tex]-3y = 6[/tex]

Divide by -3

[tex]y = -2[/tex]

That is a right triangle. So I think it’s a2+b2=c2. So it will be 7 the power of 2 plus the 10 the power of 2. So, it will be 49 plus 100, and that will be 149. Then it’s gonna be c2=149. How you gonna remove the 2, using square root. So square root of 149 is 12.2. So your final answer is 12.2. Check the calculator if I am right.

Answers

Answer:

Option B

83°

Step-by-step explanation:

Since,

To prove it as a kite then according it,

Ac should be a perpendicular bisector of BD

Hence,

<APB = 90°

Also given,

<APB = (x + 7)°

Therefore, by the problem,

=> x + 7 = 90

=> x = 90 - 7

=> x = 83°(Ans)

Answers

Answer:

[tex]f(3) = \frac{11}{2}[/tex]

[tex]f(5) = \frac{15}{2}[/tex]

[tex]f(17) =\frac{39}{2}[/tex]

Step-by-step explanation:

Given

[tex]f(n) = 3 + n - \frac{1}{2}[/tex]

Solving (a): The 3rd term

This implies that n = 3

So:

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

Take LCM

[tex]f(3) = \frac{6 + 6 -1}{2}[/tex]

[tex]f(3) = \frac{11}{2}[/tex]

Solving (b): The 5th term

This implies that n = 5.

So:

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

Take LCM

[tex]f(5) = \frac{6 + 10 - 1}{2}[/tex]

[tex]f(5) = \frac{15}{2}[/tex]

Solving (c): The 17th term

This implies that n = 17

So:

[tex]f(17) = 3 + 17 - \frac{1}{2}[/tex]

Take LCM

[tex]f(17) =\frac{6 + 34 - 1}{2}[/tex]

[tex]f(17) =\frac{39}{2}[/tex]

why is it so important to check the accreditation of a private higher learning institution? explain two reasons​

Answers

Answer:

Helps determine if an institution meets or exceeds minimum quality standards. Helps students determine acceptable institutions for enrollment. Assists institutions in determining acceptability of transfer credits.

Step-by-step explanation:

The reasons why checking accreditation of a private higher learning institution includes:

It helps to access the quality of education at the institution.

It helps student determine which institutions to enrol in.

Accreditation of Higher learning institutions

Checking the accreditation status of institutions is not only limited to private higher learning institutions, but includes public ones too.

It is therefore important to access the accreditation status of an institution in order to have a feel of what to expect regarding the quality of education in such institution.

Consequently, students have first hand information as to what school to apply to depending on the intended course of study.

Step-by-step explanation:

oh law of sines   soo  sin(A) / a = Sin(B) / b

2a)

here DE = side f   then let's find that side with law of sines and plug side f in as 'a' in law of sines , so

Sin(28) / a = Sin(54) / 31  ( where a = f = DE )

can you do the algebra here Emily?  or do you want me to show that?

Sin(28) *31 / Sin(54) = a

17.989 =a

18.0 =a       (rounded to nearest 10th)

DE = 18.0 m

2b)

find RT  where RT = side a

since they give use 2 of the other sides of the triangle we can quickly figure out the S angle.   180 = 71+62+S   so  S = 47°  ( I'm going kinda fast b/c I don't know how much time you have  :? )

then Sin(A) /a = Sin(B) / b

Sin(47) / a = Sin(62) / 29

Sin(47) *29 / Sin(62) = a

24.020 = a

RT = 24.0 meters  ( rounded to nearest 10th )

2c)

they want us to find ∠X with law of sines soo

I'll just use the letter they give us for variables

Sin(X) / x  = Sin(Y ) / y

Sin(X) = x* Sin(y) / y

X = arcSin [ 14 * Sin(108) / 34 ]

X = arcSin [ 0.3916115]

X = 23.0548°

X= 23°  ( rounded to nearest degree )

2d)

they ask us to find ∠E

I'll , again, use the letter they give us for variables

Sin(E) / e = Sin( F ) / f

Sin(E) / 18 = Sin(78) / 30

E = arcSin[ 18 * Sin(78) / 30 ]

E = arcSin [ 0.5868856 ]

E = 35.936 °

E = 36 °    ( rounded to nearest degree )

Answer:

The Answer is A

Step-by-step explanation:

Trust me I just did the Assignment.

The correct function which has a constant additive rate of change of -1/4 is shown in figure 1.

What is mean by Function?

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable.

Given that;

To find the correct function which has a constant additive rate of change of -1/4.

Now, From figure 1;

Two points are (2,1) and (- 2, 2).

Hence, We get;

Rate of change = (2 - 1) / (- 2 - 2)

                        = - 1/4

Thus, The correct function which has a constant additive rate of change of -1/4 is shown in figure 1.
