Answer:
y = -1
Step-by-step explanation:
Details have been given in the question, we need to break them apart and create our equations accordingly.
"the sum of two times x and 3 times y is 5"
2x + 3y = 5
"the sum of two times x and 3 times y is 5"
x - y = 5
So, our two equations are:
2x + 3y = 5
x - y = 5
Solve using substitution method, by moving y to the other side.
x = y + 5
2(y + 5) + 3y = 5
2y + 10 + 3y = 5
Combine like terms
5y + 10 = 5
Subtract 10 from both sides
5y = -5
y = -1
Relection ( it was relected over the y axis )
Translation ( it was slide one unit down )
Answer:
Step-by-step explanation:
If we have 3 red spaces, 5 white spaces, and one blank space, there are a total of 9 spaces.
Since there are 3 red spaces, there is a chance of getting a red. However, the question asks the probability of not getting a red, so the chances of not getting a red are .
Hope this helped!
Answer:
-13
Step-by-step explanation:
Replacing x with -3 results in f(-3) = -(-3)^2 - 4, or
f(-3) = -9 - 4 = -13
