K - ( -3 ) = 12 how to solve⬆

K - (-3) = 12   When you subtract a negative number, it's the same as adding that                      number. So, your first step will be to cancel out the double                                    negative.
  k + 3 = 12   Next, subtract 3 from both sides of the equation to isolate k.
        k = 9

What is the solution of the linear system?
lozanna [386]

Answer:

(3,-4)

Step-by-step explanation:

Given

-7x - 2y = -13

x = 2y + 11

Required

Find the solution

Substitute 2y + 11 for x in the first equation

-7(2y + 11) - 2y = -13

Open bracket

-14y -77 - 2y = -13

Collect Like Terms

-14y - 2y = -13+77

-16y = 64

Solve for y

y = \frac{64}{-16}

y = -4

Substitute -4 for y in x = 2y + 11

x = 2(-4) + 11

x = -8 +11

x = 3

Hence, the solution is (3,-4)

Can anyone help me with this problem ? I would appreciate it a lot !
Scorpion4ik [409]

Answer:

D - 192

Step-by-step explanation:

So the solve this, lets use the formula for area of a triangle:

b*h / 2 = A

b is the base, h is the height.

In this case, our base is 32, and our height is unknown.

To find it we must use pythagreons theorm:

a^2+b^2=C^2

a is half of the base in this case, since tecnically this iscoceles traingle(2 same sides) cut in half is 2 right triangles.

32/2 = 16

b is the unknown, and C is the hypotenuse(longest length) which is 20:

16^2+b^2=20^2

256*b^2=400

b^2=144

b=12

So we know b, whihc is our height, is 12.

Plugging this in:

32*12 / 2 = A

384 / 2 = A

192 = A

So the area of the triangle is 192.

Hope this helps!

What is the value of 1I2L3F4
sp2606 [1]

Answer:

The next Value is E

Step-by-step explanation:

The general pattern is number-letter-number-letter and so on. Hence, the next character in the given sequence is a letter. Looking at the design of the letters, "I" is made up of 1 line, "L" is made up of 2 lines, and "F" is made up of 3 lines. Following this pattern, the next letter would consist of 4 lines. Hence the next value is "E", which is made up of 4 lines.
