Answer:

(37 + x) km

Step-by-step explanation:

To know the number of kilometers biked by Annika today, we need to add what she biked in the morning to what she biked in the evening.

From the question, she biked 37 km in the morning and x km in the evening

So the total distance biked by Annika today will be (37 + x) km

How many solutions 2x+3y=-3 and 3x + 5y = -9
Sunny_sXe [5.5K]
Since the slopes of the two lines are the not equal, they will have only one solution. The solution will be a point and can be found using the method given below.

We can find the solutions by simultaneously solving the two equations.

From first equation, the value of y comes out to be:

2x+3y=-3 \\  \\ 
3y=-3-2x \\  \\ 
y= \frac{-3-2x}{3}

Using this value of y in second equation, we get:

3x+5( \frac{-3-2x}{3} )=-9 \\  \\ 
9x-15-10x=-27 \\  \\ 
-x=-27+15 \\  \\ 
-x=-12 \\  \\ 
x=12

Using this value of x, we can find y:

y= \frac{-3-2x}{3}= \frac{-3-24}{3} =-9

Therefore, there is only one solution to the given equations is which is (12, -9)

x=50  

Step-by-step explanation:

angle 1 and 3 are corresponding angles that menas they equal the same

so set it up like this 2x+10=110 solve for x

move over the 10, subtract 10 from 110 you get 100 and divide by 2

you get 50.

Solve the equation: k^2+5k+13=0
mr_godi [17]

Step-by-step explanation:

k² + 5k + 13 = 0

Using the quadratic formula which is

x =  \frac{ - b \pm \sqrt{ {b}^{2} - 4ac } }{2a}  \\

From the question

a = 1 , b = 5 , c = 13

So we have

k =  \frac{ - 5 \pm \sqrt{ {5}^{2} - 4(1)(13) } }{2(1)}  \\  =  \frac{ - 5 \pm \sqrt{25 - 52} }{2}  \\  =  \frac{ - 5 \pm \sqrt{ - 27} }{2}  \:  \:  \:  \:  \:  \:  \\  =  \frac{ - 5  \pm3 \sqrt{3}  \: i}{2}  \:  \:  \:  \:  \:  \:

<u>Separate the solutions</u>

k_1 =  \frac{ - 5 + 3 \sqrt{3} \: i }{2}  \:  \:  \:  \: or \\ k_2 =  \frac{ - 5 - 3 \sqrt{3}  \: i}{2}

The equation has complex roots

<u>Separate the real and imaginary parts</u>

We have the final answer as

k_1 =  -  \frac{5}{2}  +  \frac{3 \sqrt{3} }{2}  \: i \:  \:  \:  \: or \\ k_2 =  -  \frac{5}{2}  -  \frac{3 \sqrt{3} }{2}  \: i

Hope this helps you
