The answer to the function is 102

First you must set up the equation

$f(10)=3(10)(2)+6(10)-18$

Then you must multiply

$f(10)=60 +60-18$

Finally, you must simplify like terms

$f(10)=102$

Terrance works part time and deposits 134.12 into his checking account every week. he began with 207.43 in the account Identify

Norma-Jean [14]

The graph has the following key features:

(1) it shows the checking balance as a function of time (ie., at a given week)

(2) the graph is linear, showing a linear relationship between the balance and time. This is because the amount deposited is the same every week.

(3) the slope of the line is 134.12, since Terrance deposits $134.12 every week. The graph's y axis has different scale which makes the graph appear to have a slope close to 1, but, nevertheless, the linear function has slope of 134.12.

(4) the y-intercept is at 207.43 because at time 0 (week 0) there was a starting balance of $207.43

(5) The function in slope intercept form:

y = 134.12*x + 207.43

Mrs. Jones bought 6 kilograms of rice. After filling 10 containers with the same

9966 [12]

There are 514 gram rice in each container.

Step-by-step explanation:

Given,

Amount of rice = 6 kg

1 kg = 1000 g

6 kg = 6*1000 = 6000 g

Number of containers = 10

Rice left = 860 g

Let,

x be the amount in each container.

Total amount of rice - Number of containers*Amount in each container = Amount of rice left

$6000-10x=860\\6000-860=10x\\5140=10x\\10x=5140$

Dividing both sides by 10

$\frac{10x}{10}=\frac{5140}{10}\\x=514$

There are 514 gram rice in each container.

The sum of 42 and a number x is 51

n200080 [17]

Answer:

x = 9

Step-by-step explanation:

"The sum of 42 and a number x is 51" in "mathy" words:

42 + x = 51

Then, subtract both sides by 42:

42 + x - 42 = 51 - 42

x = 9
