Answer:

Sample Answer: When a linear function is expressed in different forms, its slope and y-intercept remain the same. The slope from the equation is -1, and the y-intercept from the equation is 3. The slope from the table is -1, and the y-intercept from the table is −3. These are not the same functions.

Answer:

The slope formula is y2 - y1/x2 - x1.

Step-by-step explanation:

First plug in x = 1, x = 2, and x = 3 in to the equation y = 4x to find the first 3 points(Like the first three are shown for the table.) which are (1, 4), (2, 8), and (3, 12).

The slope of the table would be 9 - 3/3 - 1, after subtracting you get 6/2. You would then divide 6 by 2, which gives you 3. 3 is the slope of the table.

The slope of the equation goes through the same process. 12 - 4/3 - 1, after subtracting it's 8/2, and after dividing you get 4. The slope of the equation is 4.

This means the equation has the greater slope.

taurus [48]

2d+1/6=2d+6 (I distributed the 6 to what was in the parentheses)
2d-2d=6-1/6 (I subtracted 2d from both sides to get the variables on one side and 1/6 from both sides to get the variables by themselves)
0=35/6 (combined like terms)
0=35/6 is an untrue statement so x doesn't exist

Solve and explain <br>5s^2- 101 = 144

Reptile [31]

Answer:

S = 7

Step-by-step explanation:

Ok, so we need to find out what s is.

So let's start off with the equation:

$5s^{2} - 101 = 144\\$

So what we have to do now is add 101 on both sides:

$5s^{2} = 245$

Now we just have to isolate s and divide by 5:

$s^{2} = 49\\$

Now we just have to find the square root of 49.

This is 7.

Hope this helps :)

HURRY I NEED HELP PLS

Answer:

3,454 cm³

Step-by-step explanation:

This is a cylinder so the volume formula is $V=\pi r^{2} h$

The problem gives us the diameter (20 cm) and the height (11 cm). Since the formula uses the radius instead of the diameter, we have to divide the diameter by 2.

20 ÷ 2 = 10

The radius is 10 cm

Now, we plug our height and radius into the formula to find the volume.

$V=\pi r^{2} h\\V=(\frac{22}{7})(10)^{2}(11)\\V=(\frac{22}{7})(100)(11)\\$

V≈3,454
