First you graph the y-intercept which is 3. so you put a dot on 3 on the y axis. then you graph the slope. you go up one and then to the left 3 from the y- intercept. or you can go down one and then right 3 from the y- intercept. and you can do that for however many dots you need. just start from the y-intercept and continue from each dot

8x + 34. What does X equal

rosijanka [135]

Answer: $x=-4.25$

Step-by-step explanation:

First you put it in to y= mx+b form.

$0=8x+34$

Then you subtract 34 from both sides

$-34=8x$

Then you divide 8 from both sides

Leaving you with

$x=-4.25$

If mZMNO = 95°, mZADC = 101°, and mZMLO = 80°, then what is m/ABC, in degrees?

dem82 [27]

Answer:

This is your answer.

Step-by-step explanation:

There are different kinds of angles:

Angles below 90= Acute

90= Right

91–179= Obtuse

180= Straight Angle

181–359= Reflex Angle

360= Complete Angle or Circle.

Because 80 degrees is less than 90 degrees, Angle ABC is an acute angle.

(a) Suppose you have 9 gold coins that look identical, but you also know one (and only one) of them is counterfeit. The counterf

alisha [4.7K]

Answer:

Step-by-step explanation:

You can split the coins into 3 groups, each of them has 3 coins. Weigh group 1 vs group 2, if one is lighter, that group has the fake coin. If both groups weigh the same, then group 3 has the fake coin.

Continue to split the group that has the fake coin into 3 groups, each group has 1 coin. Now apply the same procedure and we can identify the fake coin.

Total of scale usage is 2

b) if you have $3^n$ coins then you can apply the same approach and find the fake coin with just n steps. By splitting up to 3 groups each step, after each step you should be able to narrow down your suspected coin by 3 times.

Step 1: you narrow down to group of $\frac{3^n}{3} = 3^{n-1}$ coins

Step 2: you narrow down to group of $\frac{3^{n-1}}{3} = 3^{n-2}$ coins

Step 3: you narrow down to group of $\frac{3^{n-2}}{3} = 3^{n-3}$ coins

...

Step n: Step 1: you narrow down to group of $3^{n-n} = 3^0 = 1$ coin

That's how scales work. They show your weight which is actually your downward pull by the force of gravity.
