Answer:
(- 4, - 10 )
Step-by-step explanation:
y = 5x + 10 → (1)
y = 4x + 6 → (2)
Substitute y = 5x + 10 into (2)
5x + 10 = 4x + 6 ( subtract 4x from both sides )
x + 10 = 6 ( subtract 10 from both sides )
x = - 4
Substitute x = - 4 into either of the 2 equations and evaluate for y
Substituting into (1)
y = 5(- 5) + 10 = - 20 + 10 = - 10
solution is (- 4, - 10 )
In order to develop an equation, let's use the slope-intercept form of the linear equation:
Using the points (3, 13.5) and (5, 18.5) from the table, we have:
Subtracting the second and the first equation:
Now, finding the value of b:
So the equation that represents this table is y = 2.5x + 6
Looking at the options, the correct one is E (none of the above).
We know that for all B:
So the answer is 0,5 (b.)
The factors are: (x+2) and (x-3).
Your answer is n>17 hope this helps
