Answer:
83
Step-by-step explanation:
Start by finding the first number on the Y axis,
then find the next number on the x axis, you can move up OR down if you have to
Make sure if your number is a - for instance, (-5, 1) you plot it on the negative 5 one, not the positive five.
Answer:
-30
Step-by-step explanation:
x*3y=(-2)*3(5)=-2*15=-30. Hope this helps!
Answer: x = 0, and y = -2
Step-by-step explanation:
-5x + y = -2 .........(1)
-3x + 6y = -12 ......(2)
From equation (1)
-5x +y = -2 .........(1)
y = 5x - 2 .............(3)
Now substitute for y in equation (2)
-3x + 6 (5x -2 ) = -12
Make use of 6 to open the bracket ,we now have
-3x + 30x - 12 = -12
= 27x - 12 = -12
Collect the like terms
27x = -12 + 12
27x = 0
Divide through by 27 to get the value of x
x = 0/27
x = 0
To determine y, substitute for x in equation (3)
y = 5x - 2
y = 5(0) - 2
y = 0 - 2
y = -2
Check : Substitute for x and y in equation (1)
-5x + y = -2
-5(0) + (-2) = -2
0 -2 = -2
0 - 2 = -2
Side-angle-side similarity means that when two triangles have corresponding angles that are congruent and corresponding sides with identical ratios we can say that the triangles are similar. So UV/XY and WV/ZY are equivalent and therefore, angle V equals angle Y is the correct answer.
