Steps for graphing -x^2-4x-3

Mathematics
1 answer:
sdas [7]3 years ago
3 0

Answer:

:)

Step-by-step explanation:

There are several ways to do this. The first, which I personally think is the quickest way without having to do too much math or rearranging the equation is to simply pick random points for x and solve for y.

For instance, you might try -2 for x.

- ( - 2)^2 - 4 ( - 2) - 3

= - 4 + 8 - 3

= 1

So one of your points would be (-2, 1)

Then you might choose, say, -3 for x. And after that, -1 for x. If you want to graph even more points after those (the more points, the more accurate your graph), choose -4 and 0 for x. Simply put it into the equation and find y. Then graph.

Evaluate the following log32-log64+log16
gogolik [260]
Using properties of logarithms:

log(m+n) = log(m.n)

log(m-n) = log (m/n)

we get,

log(32x16/64)

On simplifying:

log(8)

and 8= 2^3

therefore,

log(2^3)

again using another property for exponents in logarithms we get:

The first week at Javier's new job he spent $12.48, $9.50, $10.25, $4.99, and $8.59 on lunch. In the second week, he spent $3 mo
Jlenok [28]

Answer:

$0.60

Step-by-step explanation:

The mean is the average. We add up all the numbers and divide by the number of numbers.

The total for 1st week is  $12.48+$9.50+$10.25+$4.99+$8.59 = $45.81

Now, the mean:

Mean = 45.81/5 = $9.162

2nd week's total is 3 more than last week's total, so 2nd week's total is:

45.81 + 3 = $48.81

Now, Mean:

Mean = 48.81/5 = $9.762

The increase is  9.762 - 9.162 = $0.60

ACCTUALLY HELP ME??!!!!!!! NEEDED FOR TOMORROW AND 50 POINTS! will award brainliest for first answer!!
drek231 [11]

Answer:

a:c = 35:24

a:c = 20:27

a:c = 35:22

a:c = 28:27

Step-by-step explanation:

a:b = 7:3

Using cross products

3a = 7b

Divide by 7

3a/7 = b

Now we want

8b = 5c

Substitute in 3a/7 for b

8 (3a/7) = 5c

24/7a = 5c

Multiply by 7

24/7a *7 = 5*7c

24a = 35c

Divide by c

24 a/c = 35

Divide by 24

a/c = 35/24

a:c = 35:24

a:b = 4:9

Using cross products

9a = 4b

Divide by 4

9a/4 = b

Now we want

3b = 5c

Substitute in 9a/4 for b

3 (9a/4) = 5c

27/4a = 5c

Multiply by 4

27/4a *4 = 5*4c

27a = 20c

Divide by c

27 a/c = 20

Divide by 27

a/c = 20/27

a:c = 20:27

b:c = 5:11

Using cross products

11b = 5c

Divide by 11

b = 5c/11

Now we want

2a = 7b

Substitute in 5c/11 for b

2a = 7(5c/11)

2a = 35c/11

Multiply by 11

2a*11 = 35c

22a = 35c

Divide by c

22 a/c = 35

Divide by 22

a/c = 35/22

a:c = 35:22

b:c = 14:3

Using cross products

3b = 14c

Divide by 3

b = 14c/3

Now we want

9a = 2b

Substitute in 14c/3 for b

9a = 2(14c/3)

9a = 28c/3

Multiply by 3

9a*3 = 28c

27a = 28c

Divide by c

27 a/c = 28

Divide by 27

a/c = 28/27

a:c = 28:27
