How many solutions does this system have?

Mathematics
1 answer:
Savatey [412]3 years ago
4 0

Answer:

B. One

Step-by-step explanation:

Multiply the first equation by 2 and then add both equations to get rid of x:

\begin{cases}2x+8y=18,\\-2x+y=0\end{cases}

Adding both equations:

8x+y=18,\\9y=18,\\y=2

Substituting y=2:

-2x+2=0,\\-2x-2,\\x=1

Therefore the only solution to the system of equations is (1, 2) and the system has one solution.

Find the length of the longest side of the rectangle whose vertices are given. a(2, 1), b(5, 4), c(0, 3), d(3, 6)
aleksandr82 [10.1K]
First, you plot the coordinates to visualize the problem clearly. As you can see in the picture, the longest sides could either be one of those marked in red. This could be initially determined when you use visual estimation. We measure this using the distance formula: d = √[(x2-x1)^2 + (y2-y1)^2)]

Between coordinates (0,3) and (3,6)
d = √[(3-0)^2 + (6-3)^2)]
d= 4.24 units

Between coordinates (2,1) and (5,4)
d = √[(5-2)^2 + (4-1)^2)]
d= 4.24 units

They are of equal length. Both are the longest sides which measures 4.24 units.

Housing costs are what percentage of monthly net income? Use the budget sheet to calculate. Round your answer to the nearest who
schepotkina [342]

Answer:

See below  

Step-by-step explanation:

The formula for calculating percent is

% = (cost of item/total cost) × 100 %

% = (cost of item/1875) × 100 %

% = (cost of item/18.75) %  

You can use the same formula to calculate the percent for each item in the budget. For example,

Housing: % = 420/18.75 = 22 %

You can do this for each budget item and get the table below.

\begin{array}{lrr}\text{Expense} & \text{Cost} & \%\\\text{Housing} & 430 & 22\\\text{Food} & 300 & 16\\\text{Utilities} & 125 & 7\\\text{Transportation} & 320 & 17\\\text{Savings} & 500 & 27\\\text{Other} & 200 & 11\\\text{TOTAL} & 1875 & 100\\\end{array}
