Step-by-step explanation:

1.)

3x=3

x=1

2+y=0

y=-2

solution: (1,-2)

2.)

6y = -36

y = -6

-4x+12 = -12

-4x=-24

x = 6

solution: (6,-6)

Answer:

Top: x=1, y= -2

Bottom: x= 6, y= -6

Step-by-step explanation:

Top:

Isolate x for y: 2(3+y) + y = 0

Simplify: 6+3y=0

Isolate y for 6+3y=0: y = -2

For x= 3 + y: x = 1

Bottom:

Isolate x for : -4x - 2y= -12: x= $\frac{-6 + y}{2}$

Simplify: 6y+ 12 = -24

Isolate y for 6y+ 12 = -24: y = -6

For x= $-\frac{-6 -6 }{2} = 6$ : x = 6

1.Arsenic-74 is used to locate brain tumors. It has a half-life of 17.5 days. 90 mg wereused in a procedure. Write an equation t

Sophie [7]

$1)\text{ }N_t\text{ = 90\lparen}\frac{1}{2})^{\frac{t}{17.5}}$

2) 5.625 mg will be left

Explanation:

1) Half-life = 17.5 days

initial amount of Arsenic-74 = 90 mg

To get the equation, we will use the equation of half-life:

$\begin{gathered} N_t\text{ = N}_0(\frac{1}{2})^{\frac{t}{t_{\frac{1}{2}}}} \\ where\text{ N}_t\text{ = amount remaining} \\ N_0\text{ = initial amount} \\ t_{\frac{1}{2}\text{ }}\text{ = half-life} \end{gathered}$ $N_t\text{ = 90\lparen}\frac{1}{2})^{\frac{t}{17.5}}$

2) we need to find the remaining amount of Arsenic-74 after 70 days

t = 70

$\begin{gathered} N_t=\text{ 90\lparen}\frac{1}{2})^{\frac{70}{17.5}} \\ N_t\text{ = 5.625 mg} \end{gathered}$

So after 70 days, 5.625 mg will be left

A school cafeteria uses 10

gladu [14]

Using proportions, it is found that there are 5 cups of milk in each bowl of chocolate pudding.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

The cafeteria used 10 quarts for 8 bowls, hence the number of quarts per bowl is:

10/8 = 1.25

Each quart has 4 cups, hence the number of cups is:

4 x 1.25 = 5 cups.

These dot plots show the ages (in years) for a sample of two types of fish.

drek231 [11]

*Select two choices: one for the centers and one for the spreads.

A. Centers: The sharks have a lower median age than the koi

B. Spreads: The ages of the koi are more spread out.

C. Centers: The sharks have a greater median age than the koi.

D. Spreads: The ages of the sharks are more spread out

(See attachement for diagram)

Answer:

A. and B.

Step-by-step explanation:

Measure of center that can be used in stating the differences between Koi and Shark is the median.

Examining the dot plot, the median age for Sharks is 20.

The median age for Koi is the 14th data point, which is 40.

Thus, for the center, we can conclude that Sharks has a lower median age than Koi.

For the spread, the larger the range, the more spread out the data are.

Thus:

Range for Sharks = 30 - 10 = 20

Range for Koi = 70 - 25 = 45

Therefore, we can conclude that the ages of Koi are more spread out.
