Mathematics
1 answer:
damaskus [11]3 years ago
8 0

Answer:

The required inequality is: 20\leq E or E\geq 20E

The graph is shown in figure.

Step-by-step explanation:

Consider the provided information.

Edith must read for a minimum of 20 minutes.

Let the number of minutes is represented by x.

Edith must read minimum of 20 minutes that the value of x can be 20 or greater than it.

Thus, the required inequality is:

20\leq E or E\geq 20E

Now draw the graph of the inequality.

Use a dot or close circle to represents ≤ or ≥.

The value of E is greater than or equal to 20 and the required graph is shown in figure.

Imagine a world in which only decimal,not fractions,are used.how would your life be different
Firdavs [7]
This answer depends a bit on your age, the types of activities you partake in and the kind of work you do/are planning to do but here goes:

I am thinking of some uses of fractions where decimals are not typically used. One might be cooking. Often the ingredients (1/2 cup of four and so on) are measured using fractions. If you were in a world with decimals you might need to make (1/3) the servings of a recipe that calls for 1/4 of a cup of some ingredient and instead of 1/12 have to deal with a long repeating decimal that probably would need to be approximated so would not be precise.

While on the subject of food ordering pizza (1/2 with pepperoni, 1/4 mushrooms and 1/4 plain) would be doable after you got used to it but probably not as comfortable. Dividing up slices of pizza among friends (one slice is usually 1/8 of a pie) might be awkward though eventually doable.

Estimation - the biggest issue is exactitude versus estimation. When we use a fraction like 1/3 that is an exact value, but when we use .333 or .3333333 no matter how many 3s we use we are only estimating because the 3s go on forever and we can't write them forever. Yes, we can use .3 (with a bar over the 3, but now try to multiply that with .456565656 with a bar over the 56. This becomes practically impossible unless we estimate ... so the biggest issue would be that you would lose precision in many calculations and measurements and have to deal with answers that are good enough (but not exact).

Now say you work on some major car company or you design bridges or you are a scientist developing medicine that cures diseases, would not you want the ability to measure and compute precisely? If I split the pizza up wrong it is not a big deal. If I use a little more flour or a little less than I should in the recipe it might not make much of a difference in the end but if I am doing something that impacts the health, safety or well being of another human being, I would not want to live in a world where I have to estimate and can't count on having the exact, precise value.

What is the equation of a line with a slope of -2 that passes through the point (6,8)
kakasveta [241]

Answer:

Step-by-step explanation:

hello :

the point-slope formula is :  

y - y_1 = m(x - x_1) the point is A(x_1 , y_1 ) , m : the slope

in this exercice :  x_1 = 6            y_1 = 8             m = -2  

so : y - 8 = -2(x - 6)   ...an equation for this line .

If m=8, how many solutions are there for the expression m-8?
ss7ja [257]

Answer:

1 solution, 0

Step-by-step explanation:

In algebra, a variable can be equal to any amount of numbers depending on how it is used. In this case, m is only equal to the one value of 8, and therefore only has <u>one solution.</u>

m - 8

(8) - 8
