Answer:

y = 0.75x + 9

Step-by-step explanation:

Given:

A mother gives birth to a 9 pound baby. Every 4 months, the baby gains 3 pounds. If x is the age of the baby in months, then y is the weight of the baby in pounds. Find an equation of a line in the form y = mx + b that describes the baby's weight.

y = ________________

Solve:

For the equation of the line of the form y = mx + b:

'm' which is the slope of the line

' b' which is the y-intercept and that is the value of y when x is equal to zero.

The slope is the rate of change of y per change in x.

"y" would represent the dependent variable which is the weight of the baby and "x" represents the independent variable which is the number of months or the age of the baby in months.

At birth represents the beginning of time for the baby. Lets call this month zero. Hence,

x = 0 y = 9 ⇒ at birth

x = 4 y = 12

x = 8 y = 15

x = 12 y = 18

Now we find the slope between each point. Since the common difference of y is 3 and the common difference in x is 4, the slope will be

Slope = y/x = 3/4

Therefore, the equation of the line that represents this relationship is

y = (3 / 4)x + 9

y = 0.75x + 9

The measure of an angle is 131°. What is the measure of its supplementary angle?

sp2606 [1]

Answer:

the supplementary angle to 313 would be 49.

Step-by-step explanation:

the supplement of an angle is when tow angles add up to equal 180 degrees. therefore, if you subtract 131 from 180, you would get the answer of 49 degrees.

WHAT WOULD THIS BE!?!!!!!

Answer:

B 9

Step-by-step explanation:

Use the rule of exponents for a division. To divide two powers with the same base, write the same base and subtract the exponents.

$\dfrac{a^m}{a^n} = a^{m - n}$

Now do it with your numbers.

$\dfrac{3^4}{3^2} = 3^{4 - 2} = 3^2 = 3 \times 3 = 9$

Which number line best shows how to solve −8 − (−2)? (5 points)

aliya0001 [1]

A number line from negative 10 to 10 is shown, with numbers labelled at intervals of 2. An arrow is shown from point 0 to negative 8. Another arrow points from negative 8 to negative 6. Therefore, option C is the correct answer.

<h3>What is a number line?</h3>

A number line is a straight line with numbers placed at equal intervals. Positive numbers are placed to the right of 0 and negative numbers are placed to the left of zero.

When a number (x) is added x unit is moved to the right while if a number (x) is subtracted x unit is moved to the left.

Now, solve -8 - (-2)

= -8 + 2=-6

So, a number line from negative 10 to 10 with numbers labelled at intervals of 2. An arrow is shown from point 0 to negative 8 then since 2 is added, we move 2 units right from negative 8 to negative 6.

Therefore, option C is the correct answer.
