Answer:

-2

Step-by-step explanation:

The answer is -2

Explanation:

First of all we need to identify the problem.

Y= -X-4

We can tell already from this that the X is going to be negative.

If X=-2

Now we can change the problem to:

Y= -2-4

And can even change it to

-2-4

Well the way I learned it

A negative number minus a negative number is a negative number

A positive number minus a positive number is a positive number

Simple Right?

So what's a negative number minus a positive number?

Its a negative number!

So the answer is -6

Answer:

x1= -6 and x2= 5/3

good luck

Answer:

9

Step-by-step explanation:

final score = total points for correct answer - total points for wrong answer

total points for correct answer = 5 x 6 = 30

total points for wrong answer = 7 x 3 = 21

30 - 21 = 9 points

Answer:

x = twelve

Answer:

12

Step-by-step explanation:

(3x + 3)° + (4x + 3)° = 90°

3x + 4x + 3 + 3 = 90°

7x = 90° - 6°

x = 84/7

x = 12

Answer:

  2y

Step-by-step explanation:

Eliminating parentheses, we have ...

  30x +30y -30x -28y

Grouping like terms gives ...

  (30x -30x) +(30y -28y)

Simplifying leaves ...

  0x +2y

  2y

Answer:

No

Step-by-step explanation:

No because if a = 21, then 7 * 21 = 147 and 147 is not 28.

Answer:

288cm²

Step-by-step explanation:

The volume of a rectangular prism can be easily calculated by multiplying the height by the width by the length

Assuming that the lengths given ( 6cm, 4cm and 12cm )  are the width, height and length

If so then the volume is equal to 6 * 4 * 12

6 * 4 = 24

24 * 12 = 288

volume = 288cm²

Answer:

The answer is 288

Step-by-step explanation:

I don't want to go into detail because the first guy already did., but check your formulas and what you are given and find the answers

The equation of the function is y = 4x + 5. Find the value of y when

x = 3

x = -2

y = 4x + 5 [Equation]

The value of y when x = 3 , x = -2

y = 4x + 5 [Given equation]

[tex] \therefore [/tex] When x = 3 ,

y = 4 × 3 + 5 [Value of x is 3]

y = 12 + 5

Again, when x = -2 ,

y = 4 × (-2) + 5 [Value of x is -2]

y = -8 + 5

Answer:

Step-by-step explanation:

a line perpendicular to the give formula has a reciprocal slope and it's sign is changed also.

then m = -1/3 for our perpendicular line

y - 1 = -1/3(x -6)

y -1 = -1/3x + 2

y = -1/3x +3

there you go  :)

Answer:

Step-by-step explanation:

12(4 + 8x) + 12​=0

48+96x+12=0

96x+60=0

96x=-60

x=-60/96

x=-0.625 or -5/8

Answer:

45.5

Step-by-step explanation:

First you would find 1/3 third of 10.50 and it is 3.5, you would then do 10.50 x 4 since it said 10.50 per half a yard, so you would do times 4 and you would get 42, you would then add 42 + 3.5 which equals 45.5.

Answer:

$24.50

Step-by-step explanation:

10.50 * 2 1/3 = 24.50

Answer:

-4,1

Step-by-step explanation:

Y is at -1,1

X is at -5,0

subracting we get -4,1

since it’s rise over run

-4,1

so -4

Step-by-step explanation:

Given:

A diagram of Aram's observations.

To find:

The measure of the missing angle.

Solution:

From the given figure it is clear that the three angles [tex]52^\circ,x^\circ,68^\circ[/tex] lie on a single point and right side of a straight line.

So, the sum of angle [tex]52^\circ,x^\circ,68^\circ[/tex] must be [tex]180^\circ[/tex].

[tex]52^\circ+x^\circ+68^\circ=180^\circ[/tex]

[tex]x^\circ+120^\circ=180^\circ[/tex]

[tex]x^\circ=180^\circ-120^\circ[/tex]

[tex]x^\circ=60^\circ[/tex]

Therefore, the measure of the missing angle is [tex]x^\circ=60^\circ[/tex].
