Answer:
D
Step-by-step explanation:
since it tells you y is=1 plug that into the top equation
-1=5x+4
-1=x
and you already have y=-1
so its(-1,-1)
Answer:
7 is median, 1 is minimum, 12 is maximum, 11 is upper quartile, 2 is lower quartile
Answer:
So the value of x=3 and y =3
Step-by-step explanation:
5x + 3i = 15 + yi
To find out x , set the constant terms equal to each other and solve for x
5x= 15
Divide by 5 on both sides
x= 3
To find out y , set the ';i' terms equal to each other and solve for y
3= y
So the value of x=3 and y =3
Answer:
11.1 =x
Step-by-step explanation:
Since we have a right triangle, we can use trig functions
cos theta = adjacent side/ hypotenuse
cos 42 = x/15
Multiply each side by 15
15 cos 42 = x
11.14717238 =x
Rounding to the nearest tenth
11.1 =x
