X + 8y = 18 and — 5x + 3y = -4

atroni [7]

X+8y=18
-5x+3y=-4

Multiply the first equation by 5
Add the two equations together

5x+40y=90
-5x+3y=-4
43y=86
Y=2

Plug y into one equation to find x
X+16=18
X=2

Help me this is hard

Following PEMDAS is crucial to solving these. Please Excuse My Dear Aunt Sally

P - Parenthesis

E - Exponents

M - Multiplication

D - Division

A - Addition

S - Subtraction

Multiplication/Division and Addition/Subtraction are interchangeable.

Now then, number 1 has the following:

$4-2*409-8*96$

There are no parenthesis or exponents, but there is multiplication, so we will start with multiplying. There are two multiplication expressions in the problem.

$-2 * 409 = -818$

$-8 * 96 = -768$

Since you did that, your answer has been simplified to:

$4-818-768$

Now, all you have to do is combine your like terms. Since every term is alike, you can combine the whole expression.

$4-818-768 = -1582$

So, your final answer would be:

$4-2*409-8*96 = -1582$

Hopefully with this information, you can solve the rest. If you have any questions, let me know.

What is the solution of log4(2x-6)=2

Flauer [41]

Answer: $x=11$

Step-by-step explanation:

Remembert that, by definition:

$log_b(x)=y$ → $b^y=x$

Then, you can rewrite $log_4(2x-6)=2$ in exponential form:

$4^2=2x-6$

Now you can solve for the variable "x":

Add 6 to both sides of the equation:

$4^2+6=2x-6+6$

$22=2x$

And finally you must divide both sides of the equation by 2, then:

$\frac{22}{2}=\frac{2x}{2}\\\\x=11$

A ball is thrown into the air with an initial velocity of 22 meters per second. The quadratic function h(x)= -4.9t square +22t+5

MrRa [10]

Answer:

Height of the ball after 3 seconds = 27.4 feet.

Step-by-step explanation:

h(t) = -4.9t^2 + 22t + 5.5

h(3) means the height of the ball at time 3 seconds after the ball was thrown.

h(3) = -4.9(3)^2 + 22(3) + 5.5

= 27.4 feet

I need help with this, can someone help me?

Alinara [238K]

The answer is C cause if you rotate it the shape looks different but if it had rotational symmetry it could be rotated less than 360 degrees and still look the same
