Answer:

-4

Step-by-step explanation:

Two legs of the triangle are congruent as shown by the tick marks. This means that this is an isosceles triangle; in an isosceles triangle, the two base angles are also congruent. Which means <A and <B are congruent.

So to solve for x, set 28 and 10x+68 equal to each other.

28=10x+68

First, subtract 68 from both sides

-40=10x

Then, divide both sides by 10

-4=x

If you want to check your answer plug -4 back into the original equation.

28=10(-4)+68

28=-40+68

28=28, which is true, therefore -4 is correct.

Answer:

-3 and -4

Step-by-step explanation:

x = 1st number

y = 2nd number

set up system of equations:

2x + 3y = -18

3x + 2y = -17

elimination method:  multiply 1st equation by -2 and second by 3

 -4x - 6y = 36

+

 9x + 6y = -51

  5x = -15

   x = -3

find y:  2(-3) + 3y = -18

           -6 + 3y = -18

            3y = -12

             y = -4

Answer:

We conclude that:

[tex]\left(\:\:\frac{x^4}{\frac{3x^2}{3}}\right)^{\frac{1}{3}}\:=\:x^{\frac{2}{3}}[/tex]        

Hence, option A i.e. [tex]x^{\frac{2}{3}}[/tex]  is true.    

Step-by-step explanation:

Given the expression

[tex]\left(\:\:\frac{x^4}{\frac{3x^2}{3}}\right)^{\frac{1}{3}}[/tex]

Apply exponent rule:   [tex]\left(\frac{a}{b}\right)^c=\frac{a^c}{b^c}[/tex]

[tex]\left(\frac{x^4}{\frac{3x^2}{3}}\right)^{\frac{1}{3}}=\frac{\left(x^4\right)^{\frac{1}{3}}}{\left(\frac{3x^2}{3}\right)^{\frac{1}{3}}}[/tex]

             [tex]=\frac{x^{\frac{4}{3}}}{\left(\frac{3x^2}{3}\right)^{\frac{1}{3}}}[/tex]        ∵ [tex]\:\:\:\left(x^4\right)^{\frac{1}{3}}=x^{\frac{4}{3}}[/tex]

             [tex]=\frac{x^{\frac{4}{3}}}{\frac{\left(3x^2\right)^{\frac{1}{3}}}{3^{\frac{1}{3}}}}[/tex]

             [tex]=\frac{x^{\frac{4}{3}}}{x^{\frac{2}{3}}}[/tex]

Apply exponent rule:    [tex]\frac{x^a}{x^b}=x^{a-b}[/tex]

             [tex]=x^{\frac{4}{3}-\frac{2}{3}}[/tex]          

             [tex]=x^{\frac{2}{3}}\\[/tex]

Therefore, we conclude that:

[tex]\left(\:\:\frac{x^4}{\frac{3x^2}{3}}\right)^{\frac{1}{3}}\:=\:x^{\frac{2}{3}}[/tex]        

Hence, option A i.e. [tex]x^{\frac{2}{3}}[/tex]  is true.

Answer:

Coordinates of point R → (c - a, b)

Step-by-step explanation:

From the picture attached,

By the property of an isosceles trapezoid,

PX = AY = a

Therefore, horizontal distance of Y from the origin PY = AP - AY

PY = c - a

Vertical distance of point R from x-axis (RY) = b

Therefore, coordinates of point R will be (c - a, b).

Answer:

The expression uses multiplication and subtraction.

Multiplication and subtraction used in the expression 2x – 4

An expression is combination of variables, numbers and operators.

We need to find which operations are used in expression

2x-4

An operation is a mathematical action. Addition, subtraction, multiplication, division, and calculating the root are all examples of a mathematical operation.

Two times of x minus four.

Two times of x means we are taking product of 2 and x. Multiplication is used

2x-4 means we are subtracting four from 2x. Subtraction is used in the expression.

Step-by-step explanation:

xy = k, where k is a real constant.

When y = -1/4, x = -8.

=> k = (-8)(-1/4) = 2.

Therefore when x = 4,

y = k/x = (2)/(4) = 0.5.

In an inverse variation the value of y is 0.5

What is the value of y ?

In an inverse variation, X = -8 wheny= - 1/4.

y= - 1/4.

the value of y when x = 4

In the equation xy = k, k is a real constant.

X equals -8 at y = 1/4.

=> k = (-8)(-1/4) = 2.

Consequently, if x = 4,

y = k/x = (2)/(4) = 0.5.

In an inverse variation the value of y is 0.5.

Answer:

5. 28.39

6. 58.18

Step-by-step explanation:

5. To find x, use tangent since you know the opposite and adjacent legs

tangent is opposite/adjacent

tan(x)=20/37

x=tan-1(20/37)

x=28.39

6. you want to find the hypotonuse of XYZ to use tangent to find angle W

Sin(25)=15/x

0.423=15/x

0.423x=15

x=35.46

this is the hypotonuse

now use tangent to find W

tan(x)= 35.46/22

x=tan-1(35.46/22)

x=58.18
