Answer:
c=6
Step-by-step explanation:
first you find the total value of a and b:
a=50
b=300
then divide:
300÷50=<u>6</u>
<h2>True cause they infinitely coincide and intersect and infinitely many solutions (points)</h2>
<u>The given expressions 7+ 7x ; 7 x + 1/7 are not equivalent or equal </u>
<u>to each other </u>
<u />
<u>Step-by-step explanation:</u>
Let us firstly assume that 7 + 7x is equivalent ( to 7(x + 1/7) so that means
7 + 7x = 7(x + 1/7)
7 + 7x = 7x + 7(1/7)
7 + 7x = 7x + 1
7x + 7 = 7x + 1
Now, subtracting 7x from both sides, we get:
7x - 7x + 7 = 7x - 7x + 1
(7 - 7)x + 7 = (7 - 7)x + 1
(0)x + 7 = (0)x + 1 thus their occurs a false statement:
7 = 1 ( we know, 7 >1)
Thus we can say that
<u>7 + 7x is NOT equivalent to 7(x + 1/7)</u>
Answer:
y = (-1/4)*x+2
Step-by-step explanation:
The equation is written this way : y= mx+c
- m is the slope and c is a constant
- m = (f(4)-f(-4))/(4-(-4))= (1-3)/8 = -1/4
- y = (-1/4)*x + c
- replace x and y by the coordinates of a point to get c
- 1 = -1/4*4+c
- 1= -1+c
- c= 2
y = -1/4*x+2
Answer:
(7x^2 -1)(x - 2).
Step-by-step explanation:
7x^3 - 14x^2 - x + 2
We can factor this by grouping - that is factoring the first 2 terms and the last 2:
= 7x^2(x - 2) - 1(x - 2) <-- the x - 2 is common to both parts so we have:
(7x^2 -1)(x - 2).
