Answer:

The slope would be -x

Step-by-step explanation:

The second number in the equations y=mx+b is always the slope unless you have to plug in number and do all kinds of stuff but that's not whats in the problem now.

Answer:
-1

Explanation:
This question is written in slope-intercept form, which is this equation: y=mx+b. Here’s what each of the variables mean:

Y=the y axis
M=the slope
X=the x axis
B=the point on the line that intercepts the y axis (the y-intercept)

And we can compare y=mx+b to y=-x-1 to see what value is in place of the “m” variable to find the slope.

y=mx+b
y=-x-1

It’s not really clear until we rewrite y=-x-1 to y=-1x-1:

y=mx+b
y=-1x-1

We can see that -1 is in place of the m variable, concluding that the slope is equal to -1.

I hope this helps! Please comment if you have any questions.

A chemist wants to mix a 66% alcohol solution with eight liters of 54% alcohol solution to produce a solution that is 65% alcoho

Rzqust [24]

Answer:

We have 8 liters of 54% alcohol.

We will add "x" liters of 66% alcohol to make "8 +x" liters of 65% alcohol.

54 * 8 + 66 x = 65 (8 + x)

432 + 66x = 520 + 65x

x = 88 liters

The minute hand of a clock is 1.4 centimeters long. How far does the tip of the minute hand travel in 40 minutes? (Round your an

ozzi

Answer:

2.93cm

Step-by-step explanation:

I have to admit, this stumped me but I got o work and here's what I have for you. Hope this helps. TIP: remember it is the minute hand not any other hand.

For this one you will have to find the circumference of the clock because as the min hand goes round and round, it will act as a radius and it will go in a circular motion.

Formula will be π2r= 3.l4 * 2 * 1.4cm=8.792cm per every one revolution of the minute hand. Remembering that for the minute hand to revolve round the clock it has to cover 1 hr = 60min. For you to get the total circumference,

you'll have to take 8.792cm but since it is per every one revolution of the minute hand, multiply it by 40/60min. The answer will be 2.93066cm before rounding off. After rounding off you will have 2.93cm. Quite lengthy but I assure you after practicing you'll have at your fingertips.

Answer:

c = 160 - 3(45)

Step-by-step explanation:

if c = the number of characters left;

160 = maximum number of characters that can be used in a text

3*45 = number of characters in sentences already used. (There are 3 sentences of 45 characters.)

(# of char left) = (max # char) - (# char already used) so:

c = 160 - 3*(45)

c = 160 - 135

c = 25
