Answer:

If the slopes are different, there is one solution.

If the slopes the same but the y intercepts different, there is no solution.

If the slopes and y intercepts are the same, there are infinitely many solutions.

2x + y = 4

2y = 6 - 2x

Solve for y on both

y = 4 - 2x

y = 3 - x

They are both different, so there is one solution

Step-by-step explanation:

What is the function to 5c+4=2 (c-5)
Vinvika [58]
To solve the function we proceed as follows:
5c+4=2(c-5)
opening the parentheses we get:
5c+4=2c-10
putting like terms together we get
5c-2c=-10-4
3c=-14
c=-14/3

If a = 7 - 4√3, find the value of a + 1/a​
irga5000 [103]

Answer:

Step-by-step explanation:

To calculate a+1/a, we first need to calculate for a.

a = 7 - 4 * \sqrt[2]{3}

square root of 3 = 1.73

a = 7 - 4 * 1.73

a = 7 - 6.9

a = 0.1

0.1 + 1 / 0.1 = 0.1 + 10 = 10.1

Now, in case 4 wasn't being multiplied with the square root of 3, and instead, it was four root of 3, I am gonna do the calculations again:

a = 7 - \sqrt[4]{3}

a = 7 - 1.31

a = 5.69

5.69 + 1 / 5.69 = 5.69 + 0.17 = 5.86

Hope I Helped!

The length of a rectangle is five more than the width. The perimeter is 130cm. What is the area?
Evgen [1.6K]
<h2>Greetings!</h2>

Answer:

≅ 586.8

Step-by-step explanation:

Take x to be the width, if the length is 5x bigger than the width, then this can be shown by 5x.

The total perimeter is:

(2 * x) + (2 * 5x) because each side has another parallel one.

This means that 2x + 10x = 130

12x = 130

Divide both sides by 12:

\frac{12x}{12} = \frac{130}{12}

x = \frac{65}{6}

So the area = length * width

x * 5x = area

Substitute the values in:

\frac{65}{6} * (5*\frac{65}{6}) = 586.8055... ≅ 586.8

So the approximate area is 586.8
