Answer:
2; 3; 80; 1; -40; 1; -240 (answered from left to right then the next line)
Step-by-step explanation:
This is a question on fractions and solving algebraic equations. If you wish to venture further into it/understand this topic better, you may want to follow my Instagram account (learntionary), where I post some of my own notes on certain topics and also some tips that may be useful to you :)
I don't know. I'll have to figure it out.
Probability =
(number of successful possible results) / (total possible results) .
Total possible results for the spinner . . . 8
Successful ones (getting a 1, 2, 3, 4, or 5) . . . 5
Theoretical probability = 5/8 .
So you expect (5/8 of 150) spins to be successful.
(5/8 times 150) = 93.75
Yes !
93 or 94 is a good answer.
First it is reflected in the x axis (beacuse the x value becomes negative but the y values stays the same)
second its dilated by a factor of a half ( the sides of the figure are reduced by a half)
then its translated 2 units to the left and 2 units upwards
Answer:
x = -3
Step-by-step explanation:
y = -x + 2
7x + 4y = -1
Subsitution method: (Substitute y)
7x + 4(-x+2) = -1
Expand.
7x + (-4x + 8) = -1
One plus and one minus make one minus. Two plus makes a plus.
7x -4x + 8 = -1
Simplify.
3x + 8 = -1
Isolate 3x.
3x = -1-8
= -9
Find x.
x = -9 ÷ 3
= -3
