Answer:

AB≅AC  (two legs of isosceles triangles are always equal)

6x-14 = 4x+20

2x-14 = 20

2x = 34

x = 17

Base ⇒ 7x-12

           = 7(17)-12

           = 119-12

           = 107

Answer:

x=17, 107

Step-by-step explanation:

Since it is given that the triangle is isosceles, we can make the following equation:

6x-14=4x+20

x=17

To find the base (7x-12), all you have to do is plug in the value of x

7x-12

7*12-12

107

A. x = 3
B. x = -3
C. x = -9
D. x = -11/3

Correct answer will get brainiest!

Answers

Answer:

C

Step-by-step explanation:

Given

6x + 8 = 3x - 19 ( subtract 3x from both sides )

3x + 8 = - 19 ( subtract 8 from both sides )

3x = - 27 ( divide both sides by 3 )

Absolute value equations are equations where the variable is within an absolute value operator, like |x-5|=9. The challenge is that the absolute value of a number depends on the number's sign: if it's positive, it's equal to the number: |9|=9. If the number is negative, then the absolute value is its opposite: |-9|=9.

If –y + 2x^2 – x = -5y^3 then find dy / dx in terms of x and y.

Answers

Answer:

dy/dx = [tex]\frac{4x-1}{1-15y^{2} }[/tex]

Step-by-step explanation:

-y + 2x²- x = -5y³

2x² - x = y - 5y³

4x - 1 = dy/dx - 15y².dy/dx

dy/dx(1 - 15y²) = 4x - 1

dy/dx = [tex]\frac{4x-1}{1-15y^{2} }[/tex]

To change Celsius temperatures to Fahrenheit temperatures, you can use the formula F = 95C + 32. Which answer is the best first step to solve the equation for C?

Answers

Answer: I think that the guy above is right just subtract 32.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

The first step in solving the equation for C is

Subtract 32 on both sides.

F - 32 = 95C + 32 - 32

F - 32 = 95C

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example:

2 + 3x + 4y = 7 is an expression.

We have,

To change Celsius temperatures to Fahrenheit temperatures, you can use the formula F = 95C + 32.

Solve for C.

F = 95C + 32

Step 1:

Subtract 32 on both sides.

F - 32 = 95C + 32 - 32

F - 32 = 95C

Divide both sides by 95.

(F - 32)/95 = C

C = (F - 32) / 95

Thus,

The first step in solving the equation for C is

Subtract 32 on both sides.

F - 32 = 95C + 32 - 32

F - 32 = 95C

Find the midpoint of the line segment joining the points (9,2) and (-3,-2)

Answers

Answer:

(3,0)

Step-by-step explanation:

The midpoint formula is as follows:

[tex]( (x1+x2) /2, (y1 + y2) /2 )[/tex]

x1 would be 9, x2 would be -3, y1 would be 2, y2 would be -2. When plugged in, you should get 6/2, and 0/2 for y. When simplified, x would be 3 and y would be 0. This means that the midpoint of the line segment is (3,0)

Which of the following is equivalent to -(7/4) ?

A. 7/-4



B. -7/-4



C. 4/-7



D. 7/4

Answers

Answer:

A

Step-by-step explanation:

-(7/4) equals -7/4 or negative seven forths. Its doesn't matter where the negative sign is as long there's only 1 of them and that its still 7/4.

So through process of elimination, we take out B because theres 2 negative, which make a positive, our answer is negative

C is wrong because its 4/7, not 7/4

D is wrong because it's positive, leaving us with A

What is Trigonometry?

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

The given triangle is ABC which is right angle triangle

AB=c

BC=14 and AC=48

We have to find the value of c

By Pythagoras theorem, in a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides

AB²=AC²+BC²

c²=48²+14²

c²=2304+196

c²=2500

Take square root on both sides

c=√2500

c=50

Hence, the length of c using the Pythagorean theorem is 50 units.

We know that all angles of a triangle equal 180 when added together. We have two angle measures which are 3/2x and 1/2x
***3/2x + 1/2x + x = 180 degrees***
For the other way you can switch around the positions of the angles in the equation as long as the = stays 180 so like
X + 3/2x + 1/2x = 180
180 + x + 1/2x + 3/2x
Or maybe change the 3/2x to 1 1/2x
