Answer:

± 7

Step-by-step explanation:

Given

d = \sqrt{49}, then

d = 7 or - 7, that is ± 7

Since 7 × 7 = 49 and - 7 × - 7 = 49

Answer:

7 is the square root of 49

Step-by-step explanation:

we can find it by using lcm method

or

we know 7*7 is 49

so

49/7 - 7

therefore square root of 49 - 7

Alright, to start, slope-intercept form is y=mx+b, where m is the rate is it going up/down by, and b is the starting point.

With this, the question says that Coraz started with 0 naxvips then purchased 10 each month afterwards.

From this, we can fill in the equation, using m as the rate it is going up/down and b as the starting point:

<h3>The Equation: </h3>

y=10x+0

Next, it wants a table, so let's use the equation created to do this. X is the amount of months that have gone by, deciding how many naxvips Coraz has purchased.

So, to start, lets plug in 0 months into the equation into x:

y=10(0)+0

y=0+0

y=0

The answer resulted in 0 for month 0, understandably. Month 0 was when it said Coraz had 0 naxvips on his farms. With this, it would be (0,0) for this part.

For the next month, same thing, just plug it in:

y=10(1)+0

y=10+0

y=10

The answer resulted in 10 for month 1. Month 1 was when it said Coraz purchased his first batch of 10 naxvips. With this, it would be (1,10) for this part.

Again, with 2 months

y=10(2)+0

y=10+0

y=20

The answer resulted in 20 for month 2. Month 2 was when he got another 10 naxvips. With this, it would be (2,10) for this part. However, see the pattern? For every month, there will be 10 more naxvips added. With this, we can write out the table for it as well:

<h3>The Table:</h3>

(X, Y)

0, 0

1, 10

2, 20

3, 30

4, 40

etc..

1/2y+2/5=4 2/5 how do I solve this matter
Inessa [10]

Answer:

y =8

Step-by-step explanation:

1/2y+2/5=4 2/5

Subtract 2/5 from each side

1/2y+2/5-2/5=4 2/5-2/5

1/2 y = 4

Multiply each side by 2

1/2y *2 = 4*2

y = 8

3.8*10 to the 9th power divided by 4*10 to the 2nd power
user100 [1]

Answer:

9.5\times 10^{6}

Step-by-step explanation:

1. Divide the coefficients and the exponentials separately

\dfrac{3.8 \times 10^{9}}{4 \times 10^{2}} = \dfrac{3.8}{4} \times \dfrac{10^{9}}{10^{2}}

2. Divide the coefficients

\dfrac{3.8}{4} = 0.95

3. Divide the exponentials

Subtract the exponent in the denominator from the exponent in the numerator.

\dfrac{10^{9}}{10^{2}} = 10^{(9 - 2)} = 10 ^{7}

4. Re-join the new coefficient and the new exponential

\dfrac{3.8 \times 10^{9}}{4 \times 10^{2}} = 0.95 \times 10^{7}

5. Put the new number into standard form

The number before the power of 10 must be greater than or equal to one and less than 10.

Multiply the answer by 10/10.

(0.95 \times 10^{7}) \times \dfrac{10}{10} = (0.95\times10) \times \dfrac{10^{7}}{10} = \mathbf{9.5\times 10^{6}}

Prove that for a,b,c E ℤ, if a ❘ ( ab + c ), then a I c.
zhenek [66]

Answer:

True.

Step-by-step explanation:

Let a,b,c integers  and a | (ab+c), that is to say that there exist a integer k such that ab+c = ka. Then:

ab+c = ka

c = ka-ab

c = a(k-b). So, c is a multiple of a, that is a | c.
