So given x=-1, you can substitute it for x in the second equation.
-8(-1)+y=14
y+8=14
y=6
So the solution is (-1,6)
Answer:
45 cm^2
Step-by-step explanation:
The area of a triangle can be found using:
a= (b*h)/2
We know the base is 18 cm and the height is 5 cm. Therefore, we can substitute 18 in for b, and 5 in for h.
a=(18*5)/2
Multiply 18 and 5 first
a=90/2
Divide 90 by 2
a=45
So, the area is 45 cm^2
<u>Answer:</u>
The correct answer option is C. 12/13.
<u>Step-by-step explanation:</u>
We are given a right angled triangle with two known sides and we are to find the measure of the angle O.
For finding the measure of O, we will use sine for which we need to find the value of the value of the hypotenuse (MO).

Now that we know the length of the hypotenuse, we can find sin (O).

Therefore, the correct answer option is C. 12/13.
