Answer:

ans: D

Step-by-step explanation:

suppose

y = 3x +1 be equation••••••1

and

y = -2x - 4

-y= 2x + 4 be equation ••••••2

add equation 1 and 2 as

y = 3x + 1

-y = 2x + 4

0 = 5x + 5

so ,

5x = - 5

x = - 1

put x In either equation 1 or 2 to get y= - 2

OR,

since given equation intersects each other ,

use substitution method ,

Answer:

Step-by-step explanation:

Step 1: Find the total fraction of raisins he gave to his brothers

Step 2: Find the lowest common multiple(Lcm) of 6 and 4

Lcm of 6 and 4 = 12

Step 3: Add the fractions

= $\frac{2+ 3}{12}$

= $\frac{5}{12}$

Step 4: To find the fraction that he kept, you will subtract the total fractions he gave his brothers from 1.

$1 - \frac{5}{12} \\= \frac{12-5}{12} \\= \frac{7}{12}$

Final answer

The fraction that he kept = $\frac{7}{12}$

Estimate the answer by rounding each fraction to the nearest whole number and then adding.

Natasha_Volkova [10]

Answer:

Step-by-step explanation:

First, we round the fractions.

If a fraction is half or more it rounds up, and if the fraction is less than half it rounds down.

7/10 is greater than half so it rounds up and we add 1 to 13 to get 14.

1/8 is less than half so we round down and remove the fraction so we are left with 10.

Then we add.

14+10=24

Answer:

3¼

Step-by-step explanation:

$formula \frac{{y}^{2} - {y}^{1} }{ {x}^{2} - {x}^{1} }$

We take any of the two points shown in the question. I will take (-3, 1) and (1, 14).

x¹ = -3

y¹ = 1

x² = 1

y² = 14

Now, we sub these figures into the formula.

$\frac{14 - 1}{1 - ( - 3)}$

This leaves us with 14-1/1+3, which we can make into 13/4

13/4 = 3¼

Disclaimer: It is not actually x (or y) in the power of two, but a way to distinguish one x (or y) from the other. It is a label of sorts.

Does anyone know how to do this?

Mnenie [13.5K]

Answer:

Step-by-step explanation:

The question:

10^4= 10000

4^10=1048576

1048576x10000= 10485760000

4^5= 1024

10485760000/1024= 10240000

A. 262144 (NO)

B. 2.62144e+14 (NO)

C. 10000x1073741824= 1.0737418e+13 (NO)

D. 10000x1024= 10240000 (YES)

Hope this helps ^^
