answer pls : y- (-3y)

Answers

Answer:

4y

Step-by-step explanation:

When you subtract an already negative number then the two "minus signs" will become one addition sign and it just becomes y + 3y which is 4y

(Just for example: x- (-8x) would turn into x + 8x and the answer would be 9x)

Answer: 4y

Explanation: This is a little tricky, but since it is subtracting a negative, it is just adding 3y to y, which gives you 4y

Step-by-step explanation:

Step 1: Define

Set up equation.

mAB + mBC = mAC

x + 4 + 4 = 3x + 2

Step 2: Solve for x

Combine like terms:                     x + 8 = 3x + 2Isolate x terms:                             8 = 2x + 2Isolate x term:                               6 = 2xIsolate x:                                        3 = xRewrite:                                         x = 3

Step 3: Find AB

Define:                              mAB = x + 4Substitute in x:                 mAB = 3 + 4Add:                                  mAB = 7

Please help!! Why is sin(20) = sin(160) = -sin(200) = -sin(340)?

Answers

These relations all follow from the identity,

sin(x - y) = sin(x) cos(y) - cos(x) sin(y)

Notice that 160° = 180° - 20°, so if x = 180° and y = 20° above, we get

sin(160°) = sin(180°) cos(20°) - cos(180°) sin(20°)

We know sin(180°) = 0 and cos(180°) = -1, so we end up with

sin(160°) = sin(20°)

For the other, notice that 200° = 360° - 160°, and 340° = 360° - 20°.

Answer:

Step-by-step explanation:

sin 20 is the same as sin 60 because 180-60=20. sin 20 is the same as -sin200 because 200-180=20

sin 340 is the same as sin 20 because 360-340=20. So all four of these connect and they all equal 20. Also, they all equal .3420 (rounded)

Solve for the length of the hypotenuse

Answers

Answer:

5000

Step-by-step explanation:

In a right triangle ,

[tex] {c}^{2} = {a}^{2} + {b}^{2} [/tex]

[tex] = > c = \sqrt{ {a}^{2} + {b}^{2} } [/tex]

where -

c = hypotenusea & b = the other two sides of the triangle

According to the question , let the hypotenuse of the triangle be 'c' . So ,

[tex]c = \sqrt{ {3000}^{2} + {4000}^{2} } [/tex]

[tex] = > c = \sqrt{9000000 + 16000000} [/tex]

[tex] = > c = \sqrt{25000000} = 5000[/tex]

Hence , c = 5000

Answer:

5000

Step-by-step explanation:

[tex]3000^{2}[/tex] + [tex]4000^{2}[/tex] = 25000000

[tex]\sqrt{25000000}[/tex] = 5000

Can someone help me with this please

Answers

Answer:

Step-by-step explanation:

4) the first thing to notice is that the sides a and c are the same.. that's what the small marks are telling  you...  that are the same length. and since they are.. this is an isosceles triangle and the two angle at the base  .. along the b side will be the same.. so solving y is just the same as  A or 52°

then to solve for x we also need to use that the triangle add up to 180° on those inside angles..

180= 52+52+14x+6

maybe you can solve it from here.. but i'll do it quickly

70 = 14x

5=x

5) the exterior angle at C is 146 the total angle is 180 so the angle inside the triangle is 180=146+x      x= 34°

then use that the interior of the triangle add up to 180 again

180 = 34 + 5y+3 + 4y + 8

180 = 45 +9y

135 =9y

15 = y

If the zeros of a quadratic function are 3 and 8, what are the factors of the function?

O C.
(X + 8) and (x + 3)
OD.
(x - 8) and (x-3)

Answers

Answer:

OD

Step-by-step explanation:

The zero x=8 will make the factor (x-8) = 0 and the zero x=3 will make the factor (x-3) = 0.

so it's (x-8) and (x-3)
