Isosceles triangle= 2 concurrent sides
Right angle= 90°
So which one has two concurrent sides and a right angle? A. The right angle is marked as well as the sides.
C has 2 concurrent sides, but it's not marked as a right angle. Option B has neither of these.
6 and a 4 on the top beside it
The green and the red are similar because the angel measurements are the same and the sides on the green triangle are 1/2 of the red triangle
Answer:
y = (-1)*2^(x + 1)
Step-by-step explanation:
This one is not a line. It is something raised to a power. In addition, there is an ugly minus sign somewhere.
First of all, every answer is some sort of power of 2. All of them are 2^x but we don't exactly know how x words. It is not a simple y = 2^x because the first one is - 4 not - 2.
So there is an extra power somehow.
Try
y = 2^(x + 1) That looks promising
x = 1
y = 2^(1 + 1)
y = 2^2
y = 4
===============
Try another one
x = 2
y = 2^(2 + 1)
y = 2^3
y = 8
==============
I think you'll find that the other two are well behaved. and come to the answer (except for the minus) as they should.
What about that minus.
y = (-1)*2^(x + 1) should give a minus y value for any term.
Answer:
Look at image
Step-by-step explanation:
well y-4=3(x+5)
distribute the 3 to x and 5 --> y-4 = 3x+15
now add 4 to both sides --> y-4+4 = 3x + 15 +4
y= 3x + 19
