Answer:

a=6

Step-by-step explanation:

We are given that an equation

[tex]14a=84[/tex]

We have to solve the equation

To solve the equation we will use division property of equality

By using division property of equality

We get

[tex]a=\frac{84}{14}[/tex]

[tex]a=\frac{14\times 6}{14}[/tex]

[tex]a=6[/tex]

Hence, a=6

Answer: D. (2,0) and (2,5) have the same x-value by different y-values

In other words, the input x = 2 leads to multiple outputs y = 0 and y = 5 at the same time. A function is where any input leads to exactly one output only (assuming that input is in the domain). So whenever x repeats itself like this is when we don't have a function.

Answer:

since,

y = 2x and y = –2x + 15

then,

2x = –2x + 15

or, 4x = 15

or, x = 15/4

or, x = 3.75

Also,

y= 2x

= 2*3.75

= 7.5

Hope it helped

All the best!!

Answer:

Step-by-step explanation:

[tex]x^{2} = -2x^{2} +15[/tex]

add [tex]2x^{2}[/tex] to both sides

[tex]3x^{2} = 15[/tex]

divide each side by 3

[tex]x^{2} =5[/tex]

square root each side [tex]\sqrt{x^2} =\sqrt{5}[/tex]

[tex]x= 2.23606794[/tex] or rounded to the nearest hundredth [tex]x=2.24[/tex] or x = ±[tex]\sqrt{5}[/tex]

Answer:

No solution

Step-by-step explanation:

There are no values of x that make the equation true; hence making it have no solution.

Step-by-step explanation:

Any number squared will be a positive number.

-9 or 9 squared will equal 81.

81 + C = 103

C = 103 - 81

Answer:

sodas = 135 hot dogs = 45

Step-by-step explanation:

(S stands for sodas and H stands for hot dogs)

S + H = 180

3H+H = 180

4H = 180

H = 45

S = 45*3

S = 135

Answer: Jane needs 1 11/ 12 cups of flour more to make the cookie dough

Step-by-step explanation:

Recipe for cookie dough= 3 2/3cups of flour

Amount of flour available for Jane = 1 3/4 cups of flour

Amount of flour Jane needs to add to make cookie dough

=3 2/3 - 1 3/4

changing to improper fraction to make it easier to subtract

11/3 -7/4 = (44- 21)/12 = 23/12  =  1  11/12  cups of flour

Answer:

the proportion answer is 50

Step-by-step explanation:

Answer:

v= 13

w= -32

Step-by-step explanation:

2v+6w=-36

5v+2w=1

2w= 1-5v

2v+ (3)(1-5v)= -36

2v+3-15v= -36

3-13v =-36

3--36= 13v

39= 13v

13 = V

5×13+2w=1

65+2w=1

1-65= 2w

-64=2w

-32=w

Answer:

Step-by-step explanation:

If sum of two angles are  90, then they are complementary angles

x = 90 - 51 = 39

Answer:

The value of "X" would be 2.

To solve for x, you'd have to get it by itself. To do so, you'd simplify both sides by solv8ng the exonents of each side (2^2 = 4) and (2^3 = 8). This leaves you with 4x = 8, which you'd then divide both sides by 4. Thus getting 2 as a final answer.

I hope this helps!

If on khan

the graph is pasted

A graph is a structure that resembles a set of items in mathematics, more specifically in graph theory, in which some pairings of the objects are conceptually "connected." The items are represented by mathematical abstractions known as vertices, and each pair of connected vertices is referred to as an edge.

Step-by-step explanation:

Answer:

The graph of g(x) is a vertical translation of f(x). Although both have the same x coordinates but different y coordinates.

The graph of g is a vertical translation of the graph of f 12 units downward.

Step-by-step explanation:

The equation y=f(x)+k represents that when k is negative, the graph moves downward.

The  complete the sentence is The graph of g is a vertical translation of the graph of f 12 units downward.

Translation is the act of moving a shape or a figure from one location to another. A figure can move in translation up, down, right, left, or anywhere else in the coordinate system. Only the object's position changes during translation; its size stays the same.

Given:

f(x) = 6x

and, g(x) = 6x – 12.

As, -12 shows the vertical translation of 12 units.

Also, The graph of g(x) is a vertical translation of f(x).

Despite having distinct y coordinates, both objects have the same x coordinates.

So, The graph of g is a vertical translation of the graph of 12 units downward.

Answer is 98 because i love cheese

Answer:

She earned $20 in tips.

Step-by-step explanation:

First, you need to work out how much pay she'd get for 12 hours work:

12 x $11.25 = $135 for 12 hours work

Then, find out 2/5 of $11.25 to find out how much she would get for the 2/5 of an hour she worked:

2/5 of $11.25 = $4.50

Add both these sums together to get her total pay for hours worked:

$135 + $4.50 = $139.50

Subtract that sum from her total pay to find out how much money she earned in tips:

$159.50 - $139.50 = $20

There are 380 students and 20 teachers.

Answer:

380

Step-by-step explanation:

Let 19x =  no. of students

        x =  no. of teachers

Then,  x + 19x = 400

20x = 400

x = 20

19x = 19(20) = 380
