Answer:

No solution

Step-by-step explanation:

One solution is when two lines intercept

Infinite solutions is when two lines are on top of each other

No solution is when two lines are parallel

12 percent

Step-by-step explanation:

well because if you divide 840 by 36 you get 23.33 if you divide 840 by 3 its 280, if you divide that by 23.33 you get 12 percent.

Step-by-step explanation:

n

Answer:

k

Step-by-step explanation:

don't know

Answer:

n = 9

Step-by-step explanation:

Here we have the table:

X     Y

4     3

6    5

7     6

10   n

First, we want to find the rule.

in the first pair we have:

x = 4

y = 3

We can see that the y-value is one smaller than the x-value

y = 3 = 4 - 1 = x - 1

For the second pair we have:

x = 6, y = 5

We again can see that the y-value is one smaller than the x-value

y = 5 = 6 - 1 = x - 1

For the third pair we have:

x = 7, y = 6

Again, can see that the y-value is one smaller than the x-value.

y = 6 = 7 - 1 = x - 1

We can conclude that the rule is:

y = x - 1

For the last pair, we have:

x = 10, y = n

Then:

n = 10 - 1 = 9

n = 9

Then the table is:

X     Y

4     3

6    5

7     6

10   9

Step-by-step explanation:

Answer:

12.5

Step-by-step explanation:

y= 2/3x+4 and y=2/3x-1 1 are parallel: slope 1 = 2/3 = slope 2

the distance of line 1 and line 2 is the segment length of perpendicular line intercept two parallel lines. In other words, the distance between two parallel lines in the plane is the minimum distance between any two points lying on the lines. It equals the perpendicular distance from any point on one line to the other line.

equation of the perpendicular line pass the y intercept of line 1: y=2/3x+4  (0,4) is y = -3/2x + 4, which intercept with line 1 at (0,4)

solve the intercept of perpendicular line with line 2: get (6.9 , -6.4)

    y=-3/2x + 4 and y=2/3x-1 1 (you should be able to solve this part by self)

distance of (0,4) and (6.9,-6.4): √(6.9-0)²+(-6.4-4)² = √155.77 = 12.48 ≈ 12.5

Answer: This is true

Step-by-step explanation:

Answer:

Trinomial.

Step-by-step explanation:

A monomial has one term. A binomial has two terms. A trinomial has 3 terms.

x + y + z has 3 terms; x, y, z. So it is considered a trinomial.

Answer:

It is a function

Domain: -8, -6, -4, -3

Range: -6, -4, -3, 4

Step-by-step explanation:

Yes it is a function since there are no multiple x values

Domain are the x-values:

-8, -6, -4, -3

Range are the y-values:

-6, -4, -3, 4

Step-by-step explanation:

1. 1.643

2. -0.03

Answer:

27.7m

Step-by-step explanation:

Step 1

We find the Circumference of the nylon thread.

The formula = 2πr

The diameter of the thread = 0.88m

Radius = Diameter/2

= 0.88m/2

= 0.44m

Circumference = 2 × π × 0.44m

= 2.7646015352m

Approximately = 2.765m

Step 2

We calculate the distance

Number of revolutions = 10

Therefore, the Distance or how far the metal weight can travel =

Circumference of the wheel × Number of revolutions

= 2.765m × 10

= 27.65m

Approximately to 1 decimal place = 27.7m

Weakest to strongest data sets:

K, M, J, L

Answer:

0

Step-by-step explanation:

the x-intercept is 0 because the line intercepts the x axis at the point (0,0) so the x-intercept is 0.

Answer:

-23

Step-by-step explanation:

Given 4v-3

evaluate when v = -5

So basically we want to find the value of the expression when the variable (v) equals -5

so

* plug in -5 for v*

4(-5)-3

4*-5=-20

-20-3=-23

So we can conclude that when v = -5 the value of the expression is -23

Answer:

Explanation:

given the expression: 4v-3

if  v = -5

4v-3 (let's subsitute v)

4v-3 = 4×(-5)-3

4v-3 = -20 - 3

4v-3 = -23

delta math

Answer:

y = (x + 1)(x - 0.586) ( x - 3.414)

Step-by-step explanation:

I sure wouldn't recommend doing this by trial and error.

I made a graph of which you can see. Every time this monster touches the x axis and speeds away upward is two equal roots of y. So the square root would be one of each of them.

y = (x + 1)^2 (x - 0.586)^2 (x - 3.414)^2

are the listed roots.

The square root is

y = (x + 1)(x - 0.586) ( x - 3.414)

Do I know that this is right? I don't. But I can tell you this: if you multiply 1^2 * (-0.586)^2 * (- 3.414)^2

you get 4 just as you should. Amazing that we have tools that do that sort of thing.

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

To find the y- intercept let x = 0

From the table for f(x)

When x = 0 → f(x) = - 4

That is the y- intercept = - 4

Given

g(x) = 3 [tex](2)^{x}[/tex]

let x = 0 , then

g(0) = 3 [tex](2)^{0}[/tex] [ [tex]2^{0}[/tex] = 1 ]

       = 3 × 1

       = 3

That is the y- intercept = 3

Thus the y- intercept of g(x) is greater → B

Step by step:

 25/30 = 83.333

.30x83 = 24.9

.60 x 24.9 = 14.94

Answer:

50

Step-by-step explanation:

Let's set the number as "x". So, 30% of x is 25. We can then write this equation.

30% * x = 25

Change 30% to a decimal

0.3 * x = 25

Divide both sides by 0.3

x = 83 and 1/3

Then, to find 60% of this number, write this equation.

60% * 83 1/3 =

0.6 * 83 1/3 =

Answer:

2x + 7 > 25 ; 9

Step-by-step explanation:

Total worth of Jacob's cards = $25

Number of Bonita's card = x

Worth of Bonita's card = $2 each

Worth of Madison card = $7

Bonita and Madison cards are worth more than Jacob's card

The inequality

Bonita = 2x ; Madison = 7

2x + 7 > 25

Solving for x

2x > 25 - 7

2x > 18

x > 18 /2

x > 9

Answer:

A

Step-by-step explanation:

You need a value that keeps 79% of the previous value. 79% is 0.79 as a decimal.

You get that by taking 100% of the value and subtracting 21% of the value. Said easier (100% x - 21%x = 79% of x.

r = 0.79
