Answer: b. 160

Step-by-step explanation: just took the test

There are 160 minutes would the water level be less than or equal to 64 cups.

A relation by which we can compare two or more mathematical expression is called an inequality.

Here, The equation we're given is,

W = -0.414t + 129.549,

which an be written as,

-0.414t + 129.549 = W.

Now, We are asked to find the amount of time it would take for the water level to be less than or equal to 64 cups.  

Plugging this information in, we have:

-0.414t + 129.549 ≤ 64

To solve this, we first cancel 129.549 by subtracting from both sides:

-0.414t + 129.549 - 129.549 ≤ 64 - 129.549

-0.414t ≤ -65.549

Now divide both sides by -0.414:

-0.414t/-0.414 ≤ -65.549/-0.414

t ≥ 158.33

(When we multiply or divide both sides of an inequality by a negative number, we must flip the inequality symbol.)

t ≥ 160 minutes

Thus, There are 160 minutes would the water level be less than or equal to 64 cups.

Answer:

let x be the length of the shorter piece.

4x + x= 210

x= 42.

4x= 168

The shorter piece is 42in and the long piece is 168 in.

The length of the shorter piece will be;

⇒ x = 44 inch

What is linear expression?

A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.

Given that;

A 220-inch pipe is cut into two pieces.

And, One piece is four times the length of the other.

Now,

Since,  One piece is four times the length of the other.

Let height of shorter piece = x

Then, The height of longer piece = 4x

Hence, We can formulate;

⇒ x + 4x = 220

Solve for x as;

⇒ 5x = 220

⇒ x = 220 / 5

⇒ x = 44

Thus, The length of the shorter piece will be;

⇒ x = 44 inch

Answer:

The equation in point-slope is [tex]\mathbf{y+5=3(x-6)}[/tex]

Step-by-step explanation:

We need to write the point-slope form of the equation of the line passing through the point (6,-5) and perpendicular to the line [tex]y=-\frac{1}{3}x+4[/tex]

The general form of point-slope is; [tex]y-y_1=m(x-x_1)[/tex]

where m is slope and [tex](x_1,y_1)[/tex] is the point

We need to calculate slope.

We are given equation of line [tex]y=-\frac{1}{3}x+4[/tex] that is perpendicular to the required line.

The equation is given in slope-intercept form [tex]y=mx+b[/tex] where m is slope.

Comparing both equations we get m= -1/3

But we know that when lines are perpendicular their slopes are opposite reciprocal of each other i.e [tex]m=-\frac{1}{m}[/tex]

So, slope of required line is m = 3 (opposite reciprocal of -1/3)

Now, the equation in point-slope form having slope m=3 and point (6,-5) is

[tex]y-y_1=m(x-x_1)\\y-(-5)=3(x-6)\\y+5=3(x-6)[/tex]

So, The equation in point-slope is [tex]\mathbf{y+5=3(x-6)}[/tex]

Answer:

D. f(x) = 8x

Step-by-step explanation:

At each increasing x point, the y point increases by 8, this means that for each x increasing by 1, y increases by 8, which means y = 8x

Answer:

Fourth choice, f(x) = 8x

Step-by-step explanation:

y is going up or down and x is left or right, u riht the slope like y/x

so it's going up 8 units every 1 unit it goes to the right so it's 8/1 which is 8 so 8 is ur slope

Answer:

We conclude that the equation of this line in the slope-intercept form will be:

Step-by-step explanation:

We know that the slope-intercept form of the line equation is

[tex]y=mx+b[/tex]

where m is the slope and b is the y-intercept.

Given the equation

[tex]3z +y=2[/tex]

Writing the equation in the slope-intercept form of the line equation by simplifying it

subtracting 3z from both sides

[tex]3z+y-3z = -3z+2[/tex]

[tex]y = -3z+2[/tex]

Therefore, we conclude that the equation of this line in the slope-intercept form will be:

System A.

x-y=3

-2x+4y=-2

Solution: (5,2)

Complete the sentences to explain what steps were followed to option the system of equations below.

System B

x-y=3

2x=10

To get to system B the (first/second) equation in system A was replaced by the sum of that equation and the (first/second) equation multiplied by (4....2.....-3) . The solution to system B (is/ is not) the same as the solution to system A.

Solution:

To get system B:

First write the first equation in system A. x - y = 3

Multiply the second equation in system A by 4 and add to the first equation in system A to get:

2x = 10

x = 10/2 = 5

Put x = 5 in x - y = 3

5 - y = 3

y = 5 - 3 =2

The solution to system B is the sam as that of system A

To get to system B the second equation in system A was replaced by the sum of that equation and the first equation multiplied by 4. The solution to system B is the same as the solution to system A.

Answer:

x=47

Step-by-step explanation:

Let's solve your equation step-by-step.

180=x+3x−8

Step 1: Simplify both sides of the equation.

180=x+3x−8

180=x+3x+−8

180=(x+3x)+(−8)(Combine Like Terms)

180=4x+−8

180=4x−8

Step 2: Flip the equation.

4x−8=180

Step 3: Add 8 to both sides.

4x−8+8=180+8

4x=188

Step 4: Divide both sides by 4.

4x4=1884
