Value of x: 2.5
Value of y: -0.5
-------------------------
To find x:
x + 1 = 3x - 4
-x -x
1 = 2x - 4
+4 +4
5 = 2x
-- ---
2 2
2.5 = x
Check:
2.5 + 1 = 3(2.5) - 4
3.5 = 7.5 - 4
3.5 = 3.5
To find y:
3y = 5y + 1
-5y -5y
-2y = 1
--- ----
-2 -2
y = -0.5
Check:
3(-0.5) = 5(-0.5) + 1
-1.5 = -2.5 + 1
-1.5 = -1.5
Answer:
644 cm^2
Step-by-step explanation:
10*7*2+12*7*2+12*10=140+168+120=428
10*12-3*3=111
428+111=539
8*3*4+3*3=96+9=105
539+105=644
Answer:
- <u>200,000</u><em> 6-digit numbers can be constructed.</em>
Explanation:
Since the number is greater than 600,000, the first digit must be 6, 7, 8, or 9, so 4 different options: 4
The second, third, fourth, and fith digits can be either number 0 through 9, so 10 options for each one: 10 × 10 × 10 × 10.
Since the number must be odd and greater than 600,00, the last digit is odd, so it can be 1, 3, 5, 7, or 9, so 5 different options: 5.
Using the multiplication counting principle, you muliply the independent options to obtain the number of different combinations:
- 4 × 10 × 10 × 10 × 10 × 5 = 200,000.
The linear function that describe the situation is; 3730 = 900 + 370x.
<h3>What are independent and dependent variables?</h3>
If a variable is taking its values independently of any visible direct cause, then that variable is called independent variable.
The variables who take their values based on some other variables' values are called dependent variables.
Given; The cost of leasing a car is $900 for the down payment and processing fee plus $370 per month.
We need to find For how many months can you lease the car with $3730.
Let x be the months.
The equation for the linear function;
3730 = 900 + 370x
Therefore, the linear function that describe the situation is; 3730 = 900 + 370x.
