write the equation in slope-intercept form with y intercept of −3 and an x intercept of −4.5. Plz tell me how you got it so i no

erastovalidia [21]

The equation of the line is y = -2/3x - 3.

To find this, we first need to turn the intercepts into ordered pairs.

x intercept: (-4.5, 0)

y intercept: (0, -3)

Now we can use these two points and the slope equation to find slope.

m = (y2 - y1)/(x2 - x1)

m = (0 - -3)/(-4.5 - 0)

m = 3/-4.5

m = -2/3

Now that we have the slope, we can use slope intercept form to find the intercept.

y = mx + b

-3 = 2/3(0) + b

-3 = 0 + b

-3 = b

Which allows us to model the equation as y = -2/3x - 3

Answer:

not possible

Step-by-step explanation:

Among the first 20 natural numbers, the numbers 10, 11, 13, 14, 18, 19 are not possible to make using four 4s and the four basic arithmetic operations.

Below are listed the numbers that can be made and one possible way to do it.

{1, ((4*4)/4)/4}, {2, (4/(4+4))*4}, {3, ((4*4)-4)/4}, {4, ((4-4)*4)+4},

{5, ((4*4)+4)/4}, {6, ((4+4)/4)+4}, {7, (4-(4/4))+4}, {8, ((4*4)-4)-4},

{9, ((4/4)+4)+4}, {12, (4-(4/4))*4}, {15, (4*4)-(4/4)}, {16, ((4*4)*4)/4},

{17, (4*4)+(4/4)}, {20, ((4/4)+4)*4}

I need 20 but if you want you can answer the other questions. It would help if you numbered them if you did some of the other qu

Aleksandr-060686 [28]

Answer:

The rule for number 20 is plus 1/6, and the unknown term is 5/6.

Step-by-step explanation:1. If you skip the first two fractions and move to 1, 1/6 you will notice that it has an increase of 1/6.

2. Now, to make sure that 1/6 is the correct rule, we do have to go back to the first two fractions and give them common denominators: 1/2 turns into 3/6, and 2/3 turns into 4/6.

3. No once you look at your fractions, you can see that 1/6 is the true rule.

4. Now that we know t he rule we can turn to completing the unknown term. Since we are only moving by 1/6 it makes it very easy to add that 1/6 to your 4/6 to get 5/6. You can't simplify 5/6, so your final answer for the unknown term is 5/6.

Hope this helps :)

Can ratios have decimals in them or do all the numbers have to be integers? E.g. is 7.8:1.3:6.5 a valid ratio?

nadezda [96]

What you have is a valid ratio in theory, but it might be easier to understand if it were simplified to integers:

78:13:65

It also depends on what your teacher is asking of you.
