Which graph represents this system?

2 x minus 5 y = negative 5. y = two-fifths x + 1.


A) On a coordinate plane, 2 lines go through points (negative 5, negative 1) and (0, 1).

B) On a coordinate plane, a line goes through (0, 1) and (5, 3) and another goes through (0, negative 5) and (5, negative 3).

C) On a coordinate plane, a line goes through (0, 1) and (5, 3) and another goes through (0, 1) and (5, negative 1).

D) On a coordinate plane, a line goes through (0, 1) and (negative 5, negative 1) and another goes through (negative 5, negative 3) and (0, negative 5).

Answers

Answer 1

Answer:

Option A.

Step-by-step explanation:

When x = - 5, y = - 1,

lhs of (1) = - 10 + 5 = - 5

lhs of (2) = - 1 + 2 = 1

When x = 0, y = 1,

lhs of (1) = 0 - 5 = - 5

lhs of (2) = 1 - 0 = 1

Answer:

If Ali has $9 and spends $2 each week buying chips. This means that the equation is: y = 9 - 2x. This is because the equation is calling for the amount of money Ali has left, which means that you have to subtract 2 times the amount of weeks passed from 9.

Week 1 ---- y = $7

Week 2 ---- y = $5

Week 3 ---- y = $3

You can also notice that each week the amount of money Ali has left decreases by 2.

Hi there!

The | | signs mean that we must make the value positive, so:

(a)  | -5 + 9 | =

Solve for the inside:

| 4 | = 4

(b)

| -5 | + 9 =

Make the value positive:

5 + 9 = 14

A-4 b-14 this is because 9-5 is 4 and -5 is turned to 5 in b cause of the lines so 9+5 is 14

Translate the sentence into an equation. Two less than the product of 5 and a number equals 9. Use the variable c for the unknown number.

Answers

Answer:

The equation is: \(5c-2=9\)

Step-by-step explanation:

Since 2 less than the product of 5 and a number c is equal to 9, it follows:

\(5c-2=9\)

5•C-2=9 would be the equation

Use the Midpoint Rule with \(n=5\) to estimate the volume obtained by rotating about the y-axis the region under the curve \(y=\sqrt{1+x^3}\), \(0\leq x\leq 1\).

Answers

To estimate the volume using the Midpoint Rule with \(\displaystyle n=5\), we need to divide the interval \(\displaystyle 0\leq x\leq 1\) into \(\displaystyle n\) subintervals of equal width. Since \(\displaystyle n=5\), each subinterval will have a width of \(\displaystyle \Delta x=\frac{1-0}{5}=\frac{1}{5}\).

Now, let's calculate the volume using the Midpoint Rule. The formula for the volume obtained by rotating about the y-axis is:

\(\displaystyle V\approx 2\pi \sum _{i=1}^{n}y_{i}\Delta x\)

where \(\displaystyle y_{i}\) represents the value of the function \(\displaystyle y=\sqrt{1+x^{3}}\) evaluated at the midpoint of each subinterval.

First, let's find the midpoints of the subintervals. Since the width of each subinterval is \(\displaystyle \Delta x=\frac{1}{5}\), the midpoint of the \(\displaystyle i\)-th subinterval is given by:

\(\displaystyle x_{i}=\frac{\Delta x}{2}+\left( i-\frac{1}{2}\right) \Delta x=\frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\)

Substituting \(\displaystyle x_{i}\) into the function \(\displaystyle y=\sqrt{1+x^{3}}\), we obtain:

\(\displaystyle y_{i}=\sqrt{1+\left( \frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\right) ^{3}}\)

Now, we can calculate the approximate volume using the Midpoint Rule:

\(\displaystyle V\approx 2\pi \sum _{i=1}^{5}y_{i}\Delta x\)

Substituting the values of \(\displaystyle y_{i}\) and \(\displaystyle \Delta x\) into the formula, we can evaluate the sum and compute the estimated volume.

Answer:

The second graph

Step by Step

First, note down the points given.

(-2, -1) etc

Then find the points on the graphs and see if the line of the graph goes through the point.

(-2,-1): both lines go through this point

(0,0) both lines go through this point

(2,1) only the second graph goes through this point

Therefore, the second graph is the correct answer. You can check the last point if you want to double check.

The first graph is correct because it we see points are seen as (x, y). The points we see in the table are (-2,1) (0,0) (2.1) (4,2). These four points are all seen in the first graph.
