Answer: The slope is 2.

Step-by-step explanation:

To get the slope, use this tip: Rise over run

Count how much it rises, which is 4, and how much it "runs' which is 2. Now put rise above run which is 4/2. This simplifies to simply 2.

Answer:

The slope is 2.

Step-by-step explanation:

The points on the line are (1, -2) which can be labeled as x1 and y1, and the other is (3,2) which can be labeled as x2 and y2. you set up the equation in the slope formula, so 2 - - 2 / 3 - 1. Since there are two negatives, the subtraction signs turn into addition signs, and you get 4/2, which simplyfied is 2. Hope this helps :)

Answer:

-5

Step-by-step explanation:

The dot means multiply: so $3 \cdot 2 = 3 \times 2 = 6$

Also: 5² = 5 x 5 = 25

Therefore,

$-6-4(3 \cdot 2)+5^2$

$\implies -6-4(6)+25$

$\implies -6-(4 \times 6)+25$

$\implies -6-24+25$

$\implies -5$

Find the compound amount of $5700.00 at 11.2% p.a. for seven years compounded

vitfil [10]

Answer:

11984.18 dollars

Step-by-step explanation:

Given that an amount of 5700 dollars is invested at 11.2% p.a. for seven years compounded.

We have compound interest formula for Principal P for n years at r% compounded annually is

Final amount = $P(1+r)^n\\=5700(1+0.112)^7\\=11984.18$

Final amount for 5700 dollars at 11.2% p.a. for 7 years would be

11984.18 dollars.

Answer is 11984.18 dollars

Plz help with math thank you

Answer:

Step-by-step explanation:

Law of Sines recall Sin(A) /a = Sin(B) /b

does the above make sense?

Next we need to find the angle of A

notice that 16+75=91 :o

so angle A is only 89° ..(b/c all the way around then inside of a triangle is 180) so this is NOT a right triangle but that's okay, b/c law of sines still works fine.

then we want to find length of line AB

and if 89 = A then a = BC

and if 75 = B the b = AB (note that in the given triangle this is angle C, i'm using B , b/c you can see the difference between capital B and lower case b much easier than you can with C, & c :/ )

capitals are the angles while lower case are the length of the sides

then

Sin(89) / 29 = Sin(75) / b

solve the parts that can be put into numbers or solve for 'b' first, that means isolate 'b' all by itself on one side of the equal sign .

0.034477 = 0.965925/ b

b = 0.965925 / 0.034477

b = 28.0165

b = 28.0 ( to the nearest 10th)

we have the parts to plug in now

Sin(75) /

What is the solution to the equation? 4x - 8 = 16 need this at least by tomorrow! thank you!

Equality Properties

Step-by-step explanation:

Step 1: Define Equation

4x - 8 = 16

Step 2: Solve for x

Add 8 to both sides: 4x = 24
Divide 4 on both sides: x = 6

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Substitute in x: 4(6) - 8 = 16
Multiply: 24 - 8 = 16
Subtract: 16 = 16

Here we see that 16 does indeed equal 16.

∴ x = 6 is the solution to the equation.
