How do you solve 1/2(4b-6)=20

Mathematics

Alexxandr [17]4 years ago

Answer:

b = 23/2 or b = 11.5

Step-by-step explanation:

STEP 1: Simplify both sides of the equation.

1/2(4b - 6) = 20

(1/2)(4b) + (1/2)(- 6) = 20   (DISTRIBUTE)

2b + - 3 = 20

2b - 3 = 20

STEP 2: Add 3 to both sides.

2b - 3 + 3 = 20 + 3

2b = 23

STEP 3: Divide both sides by 2.

2b/2 = 23/2

b = 23/2

To solve you move the variables to the side and divide both sides by the factor number that doesnt have the variables your answer would be b=23/2 as a decimal is 11.5

Review the meaning of "straight angles."

Here 110 and A are "straight angles," and so 110 + A = 180   (degrees).

Then A = 70 degrees.

Answer:

For Triangle 1

a. Hypothenus = 4

b. Adjacent = 2√3

For Triangle 2:

a. Hypothenus = 2√2

b. Adjacent = 2

Step-by-step explanation:

For Triangle 1

NOTE: We shall be using angle 30°.

a. Determination of the Hypothenus.

Opposite = 2

Angle (θ) = 30°

Hypothenus =?

Sine θ = Opposite /Hypothenus

Sine 30 = 2 / Hypo

0.5 = 2 / Hypo

Cross multiply

0.5 × Hypo = 2

Divide both side by 0.5

Hypo = 2 / 0.5

Hypothenus = 4

b. Determination of the Adjacent

NOTE: We shall be using angle 30°.

Opposite = 2

Angle (θ) = 30°

Adjacent =?

Tan θ = Opposite / Adjacent

Tan 30 = 2 / Adj

1 / √3 = 2 / Adj

Cross multiply

1 × Adj = 2 × √3

Adjacent = 2√3

For Triangle 2:

a. Determination of the Hypothenus.

Opposite = 2

Angle (θ) = 45°

Hypothenus =?

Sine θ = Opposite /Hypothenus

Sine 45 = 2 / Hypo

1 / √2 = 2 / Hypo

Cross multiply

1 × Hypo = 2 × √2

Hypothenus = 2√2

b. Determination of the Adjacent

Opposite = 2

Angle (θ) = 45°

Adjacent =?

Tan θ = Opposite / Adjacent

Tan 45 = 2 / Adj

1 = 2 / Adj

Cross multiply

1 × Adj = 2

Adjacent = 2

Select the correct answer. If the zeros of a quadratic function are 3 and 8, what are the factors of the function? A. (x + 8) an
almond37 [142]

Answer:

C. (x-8) and (x-3)

Step-by-step explanation:

When we calculate the zeros of a function, we are calculating the points where that function crosses the x axis, and to do so we have to equal the function to zero and isolate X.

(x - 3) . (x-8) = 0

The only way a multiplication can have a result of 0, is that any of it's factors were equal to zero. So we can take both factors and equal them to zero and isolate x to know the function's zeros.

(x - 3) = 0\\x = 3

(x-8) = 0\\x = 8

Find the equation of line (use exact numbers)​
maw [93]

Answer:

y=3x+3

Step-by-step explanation:

Use the slope-intercept form:

y=mx+b

m is the slope and b is the y-intercept. The y-intercept is the place where x is equal to 0, and the slope is the change in the y-axis over the change in the x-axis, otherwise known as rise over run ( \frac{rise}{run} ).

If you study the graph, you can see that the line crosses the y-axis at (0,3), so 3 is the y-intercept. Insert into the formula:

y=mx+3

Now find the slope. Use the slope formula:

\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=\frac{rise}{run}

You need two points first. You can use the y-intercept (0,3) and another even point, like (1,6). Insert the values:

(0_{x1},3_{y1})\\(1_{x2},6_{y2})\\\\\frac{6-3}{1-0}=\frac{3}{1}=3

The slope is 3. Insert this value:

y=3x+3

:Done
