A. First you must start by plugging in your equation solve Y = 2(5) + 1 then you must simplify by solving your 2×5+ 1 and then you end up with Y equals 11

B. Again plug in your equation Y = 2(-5) + 1 then you must simplify by solving your 2×-5+ 1 and then you end up with Y equals -10+ one which simplifies to y = -9

I hope this helps

Here the equation given to us is,

${\blue{\boxed{\pink{y = 2x + 1}}}}$

Now what we have to do is, we have to put the value of x in brackets () in both the equations . Why we have to put value of x in a bracket?

This is because 2 is being multiplied by the variable x. So let's solve the equations

a) When x = 5, what is the value of y?

Put the value of x here

y = 2x + 1

y = 2(5) + 1

y = 10 + 1

y = 11

b) When x = -5, what is the value of y?

y = 2x + 1

y = 2(-5) + 1

y = -10 + 1

y = -9

ANSWERS :-

a) y = 11

b) y = -9

Tangent WZ and secant WV intersect at point W. Find the value of X. If necessary, round to the hundredths place.

alexira [117]

For the above figure, the formula is,

x² = WY (YV + WY)

WY = 5
YV = 12

Substituting in the above formula,

x² = 5 x (12 + 5)
x² = 5 x 17 = 85
x² = 85
⇒ x = √85 = 9.21954 = 9.220

6 A U 3 3 1 2 3 What is the equation of the line in slope-intercept form? The equation of the line is

AleksandrR [38]

Answer:

$y = -\frac{5}{4} x+5$

Step-by-step explanation:

1) First, find the slope of the line by using two points on the graph. We can see that (0,5) and (4,0) are clearly marked on the line, so let's use those points. Use the slope formula $m = \frac{y_2-y_1}{x_2-x_1}$ and substitute the x and y values of those points into it, then simplify:

$m =\frac{0-5}{4-0} \\m = \frac{-5}{4}$

So, the slope is $-\frac{5}{4}$ .

2) Now, identify the y-intercept on the graph. The y-intercept is the point at which the line intersects the y-axis. By reading the graph, we can see that the line intersects the y-axis at (0,5), so that must be the y-intercept.

3) Substitute values for $m$ and $b$ in the slope-intercept formula, $y = mx + b$ , to write the equation of the line. Since $m$ represents the slope, substitute $-\frac{5}{4}$ for it. Since $b$ represents the y-intercept, substitute 5 in its place. This gives the following answer and equation in slope-intercept form:

$y = -\frac{5}{4} x+5$

Absolute value of (0, -4/5)

Crazy boy [7]

To answer this question, we need to know what absolute value is in the first place. ANSWERS ARE AT THE BOTTOM.

Absolute value represents how far something is from 0 in a number line.

For example, lets take 4.

4 is 4 units away from 0 on the number line, so the absolute value of 4 is 4.

Now lets look at another example, -4. -4 is also 4 units away from 0, just in the other direction. However, when calculating absolute value, we do not care about the direction. Therfore, the absolute value of -4 is also 4.

Now let's look at your problem.

You want the absolute value of 0 and -4/5

Following the same principle above about the distance from 0, here are your answers:

Absolute value of 0: 0

Absolute value of -4/5: 4/5
