The numerical length of ST is 8

<h3>How to determine the numerical length of ST?</h3>

The given parameters are:

ST = 5x - 7

RT = 4x + 9

RS = 2x + 7

To calculate the length ST, we use the following equation

RT = RS + ST

Substitute the known values in the above equation

4x + 9 = 5x - 7 + 2x + 7

This gives

4x + 9 = 7x

Evaluate the  like terms

x = 3

Substitute x = 3 in ST = 5x - 7

ST = 5 * 3 - 7

This gives

ST = 8

Hence, the numerical length of ST is 8

Solve for x in each of the equations or inequalities below, and name the property and/or properties used:
nordsb [41]

Answer

a) 3/4 x = 9

    x = \dfrac{9\times 4}{3}

    x = 12

b)  10+ 3x = 5x

     2 x = 10

        x = 5

c) a + x = b

       x = b - a

d) c x = d

      x =  \dfrac{d}{c}

e)  \dfrac{1}{2} x - g < m

     \dfrac{1}{2} x< m + g

              x  < 2( m + g)

f) q + 5 x = 7 x - r

   q + r = 2 x

      x = \dfrac{q + r}{2}

Given the equation y=2x+3 and the values for x: -1, 0, 1 and 2. what are the corresponding y values?
rewona [7]

Answer:

The y's are 1, 3, 5, 7

Step-by-step explanation:

You have equation y = 2x + 3

You can think of this as a "rule" So whenever you're given a number (a value for x) you put the number in place of the x and times by two then add three.

you were given a list of numbers. They will go one at a time and have a turn being acted on by the rule.

It looks like this: first when x is -1.

take the -1 times by 2 >>>> that's -2 and then add 3 >>>> so you get 1.

y = 2x +3, x= -1

y = 2(-1) + 3

y = 1

You might have a column to write the answers in like next to their x's. Or sometimes we write them in pairs (-1 , 1)

y = 2x + 3; x = 0

y = 2(0) + 3

y = 3

(0, 3)

y = 2x + 3; x = 1

y = 2(1) + 3

y = 5

(1, 5)

y = 2x + 3; x = 2

y = 2(2) + 3

y = 7

(2, 7)

How do I use the cosine rule for these problems?
Elenna [48]

Answer:

see explanation

Step-by-step explanation:

Using the Cosine rule

a² = b² + c² - 2abcosA ← Rearranging for cosA gives

cosA = \frac{b^2+c^2-a^2}{2ab}

(a)

let a = 10, b = 7, c = 8 and A = α, then

cosα = \frac{7^2+8^2-10^2}{2(7)(8)} = \frac{49+64-100}{112} = \frac{13}{112}, thus

α = cos^{-1}( \frac{13}{112} ) ≈ 83° ( to the nearest degree )

(b)

let the angle opposite side 7 be x

Using the Sine rule

\frac{10}{sin83} = \frac{7}{sinx} ( cross- multiply )

10sinx = 7sin83 ( divide both sides by 10 )

sinx = \frac{7sin83}{10} , thus

x = sin^{-1} ( \frac{7sin83}{10} ) = 44°

The third angle can be found using the sum of angles in a triangle

third angle = 180° - (83 + 44)° = 180° - 127° = 53°

The 3 angles are 83°, 44°, 53°
