y=3

Step-by-step explanation:

2x-y=1

if x=2 then

2(2)-y=1

4-y=1

y= 4-1

y=3.

Answer:

y = 3

Step-by-step explanation:

2x - y = 1 ← substitute x = 2 into the equation

2(2) - y = 1

4 - y = 1 ( subtract 4 from both sides )

- y = - 3 ( multiply both sides by - 1 )

y = 3

Answer: y = [tex]\frac{1}{2}[/tex]x + 4

Step-by-step explanation:

       First, let us graph the points to see patterns. See attached.

     This function is linear, so we can write an equation in slope-intercept form. m is the slope and b is the intercept.

      We can find the slope with rise over run. Starting at point (0, 4) and counting up one and over 2 to (2, 5).

y = mx + b

y = [tex]\frac{1}{2}[/tex]x + 4

Answer:

B) [tex] \frac{z}{y}= x[/tex]

Step-by-step explanation:

Let's solve for x.

xy=z

Step 1: Divide both sides by y.

xy/y = z/y

x = z/y

-----------------------

Let's solve for y.

xy=z

Step 1: Divide both sides by x.

xy/x = z/x

y= z/x

-----------------------

Let's solve for z.

xy=z

Step 1: Flip the equation.

If we look through the options we see only option b is correct, therefore option B is the answer.

Correct answer is B. The value of tan²(e)+1 is sec²(e).

Triangle side length ratios are known as trigonometric ratios. In trigonometry, these ratios show how the ratio of a right triangle's sides to each angle. Sine, cosine, and tangent ratios are the three fundamental trigonometric ratios.

In geometric figures, unknown angles and distances are derived from known or measured angles using trigonometric functions. The necessity to calculate angles and distances in disciplines like astronomy, mapmaking, surveying, and artillery range finding led to the development of trigonometry.

Answer:

The second one is correct.

Step-by-step explanation:

The second one is correct.

The three identities which connect the squares of the trig ratios are

sin^2 x + cos^2 x = 1

sec^2 x = 1 + tan^2 x     ( the second one in the question is rearranged)

cosec^2 x = 1 + cot^2 x

An aid to remembering the last 2 is:

the left side ratio comes before the right in alphabetical order.

The power of quotients will be the law that would be used to simplify the expression. The correct option is B.

It should be noted that this is a mathematical rule that states that the power of a quotient is the same thing as the quotient that is gotten.

Given that the numerator p and the denominator q are raised to to the power expressed in the question separately.

The division will be:

(p/q)³

= p³ / q³

Therefore, the power of quotients will be the law that would be used to simplify the expression.

The equation of the parabola is y = (x + 3)^2 - 1

Parabolic equations are second-order polynomial equations and they have the form y = ax^2 + bx + c or y = a(x - h)^2 + k

The given parameters are

Vertex = (-3, -1)

X-intercept = (-4, 0)

A parabolic equation has the form y = a(x - h)^2 + k

Where the vertex is (h, k)

This means that, (h, k) is given as

(h, k) = (-3, -1)

Substitute (h, k) = (-3, -1) in the equation y = a(x - h)^2 + k

So, we have

y = a(x + 3)^2 - 1

Next, we substitute (-4, 0) for (x, y) in y = a(x + 3)^2 - 1

So, we have

0 = a(-4 + 3)^2 - 1

This gives

0 = a - 1

Solve for a

a = 1

Substitute a = 1 in y = a(x + 3)^2 - 1

y = (x + 3)^2 - 1

So, the required equation of the parabola is y = (x + 3)^2 - 1

Hence, the equation of the parabola is y = (x + 3)^2 - 1

If the distribution is skewed right, the mean is greater than the median.

A distribution is said to be skewed right if more than half the area under the distribution curve is to the right of the mode of the distribution. Also the tail of the distribution will be longer on the right side. In this case, the distribution is said to be positively skewed.

Then the mean of the distribution will be greater than the median of the distribution.
