Answer:

1.2×10¹² grains

Step-by-step explanation:

1 grain = 6×10⁻⁶ g

7200 kg =
7200000 g =
7.2×10⁶ g =
7.2×10⁶ ÷ 6×10⁻⁶ =
(7.2÷6)×10⁶⁻ ⁽⁻⁶⁾ =
1.2×10¹² grains

V125BC [204]

Answer:

B and E

Step-by-step explanation:

A. 8x = 2

8(4) = 2

32 = 2

B. 19 + x = 23

19 + 4 = 23

23 = 23

C. 40/x = 5

40/4 = 5

10 = 5

D. -3x = 12

-3(4) = 12

-12 = 12

E. x - x - x - x = -8

4 - 4 - 4 - 4 = -8

0 - 4 - 4 = -8

-4 - 4 = -8

-4 + (-4) = -8

-8 = -8

It would be y=4x-3 because -11 show that it went down 11 units. So if it is going to go up 8 units, -11+8 is -3.

What is the y-intercept of the function, represented by the table of values

AleksandrR [38]

Answer:

Step-by-step explanation:

The table is given below

$\left|\begin{array}{c|cc}x&y\\--&--\\-2&15\\1&6\\2&3\\4&-3\\7&-12\end{array}\right|$

We can see that the table represents a linear function since by checking its slope.

Using:

Points (-2,15) and (1,6)
Points (1,6) and (2,3)

$Slope =\dfrac{6-15}{1-(-2)} =\dfrac{3-6}{2-1}=-3$

Therefore, the values represent a linear function.

A linear equation is of the form y=mx+b

Therefore:

y=-3x+b

Using the points (7,-12)

$-12=-3(7)+b\\-12=-21+b\\b=-12+21\\b=9$

Therefore, the y-intercept of the function, represented by the table of values is 9.
