Answer:
x = 9
Step-by-step explanation:
3x = 27
3/3x = 27/3
x = 9

Answer: A) linear function</h3>
Each time x goes up by 2, y decreases by 4
This indicates we have a linear function. The slope in this case would be
m = rise/run = (change in y)/(change in x) = -4/2 = -2
The y intercept can be found by following these steps
y = mx+b
0 = -2(5)+b
0 = -10+b
10 = b
b = 10
Therefore, the equation of this line is y = -2x+10. Plug in something like x = 1 and it should lead to y = 8. The same applies for any other column of x,y values.
Answer:
C
Step-by-step explanation:
Expand the factors and compare the coefficients of like terms.
Given
(mx + 2)(3x - 5) ← expand using FOIL
= 3mx² - 5mx + 6x - 10
Compare to 12x² - 14x - 10
For the 2 to be equal, then the coefficients of like terms must be equal.
Compare coefficients of x² terms
3m = 12 ( divide both sides by 3 )
m = 4 → C
Answer: Step 3
Step-by-step explanation:
I just took the test
Answer:
Jaquan can text 300 words in five minutes and he can text 720 words in twelve minutes.
Step-by-step explanation:
If Jaquan can answer 60 words per minute, all you have to do is multiply 60 times 5 to get the answer to your first question (300), and multiply 60 and 12 to get the answer to your second question (720).
I hope this helps :D
