y = 4x + 11
y = -2x - 1

4x + 11 = -2x - 1
4x + 2x = -1 - 11
6x = -12
x = -12/6
x = -2

y = 4x + 11
y = 4(-2) + 11
y = -8 + 11
y=3

Answer:

Option A. (-2, 3)

Step-by-step explanation:

The given equations graphed are Y = 4x + 11 and Y = -2x - 1

Now for the solution to the system of equations graphed Y values will be the same or a point where these lines intersect will be the solution.

Y = 4x + 11 = -2x - 1

4x + 2x = -1 - 11

6x = -12

x = -2

Now by putting x = -2 in the first equation.

Y = 4.(-2) + 11 = -8 + 11 = 3

The common point will be (-2, 3)

Therefore option A. (-2, 3) will be the answer.

Help picture below problem 13

kirza4 [7]

The Pythagorean theorem is the idea that the sum of the two legs which are both squared is equal to the hypotenuse's length squared.

*look at the image I attached for a better explanation

By looking at the picture, we are missing the leg's length, and by using the Pythagorean theorem, we get the equation

$?^2+5^2 = 13^2\\?^2 + 25 = 169\\?^2 = 144\\? = 12$

Thus the missing side length is 12 cm

Hope that helps!

Perform the following calculations without rewriting the numbers in decimal form.

RSB [31]

Answer:

Answer will be $140\times 10^{13}$

Step-by-step explanation:

We have to perform the calculation $(1.42\times 10^{15}-2\times 10^{13})$ without changing into decimal

$1.42\times 10^{15}$ can be written as $142\times 10^{13}$

So $1.42\times 10^{15}-2\times 10^{13}=(142\times 10^{13}-2\times 10^{13})$

Now taking $10^{13}$ common

$10^{13}(142-23)=140\times 10^{13}$

Do you solve math in parentheses last or first

Flura [38]

It has to be solved first.

Step-by-step explanation:

Parentheses has to be solved first according to the BODMAS Principle which is Brackets Open Division Multiplication Addition and Subtraction
If this is not followed, the answers will be different and will not get the right answer.

It is the same as PEDMAS which is Parenthesis Exponents Division Multiplication Addition and Subtraction
