Answer:
<em>THE ANSWER IS </em>6
Step-by-step explanation:
7 divide by 14 is 1/2, and 7 is basically a half of 14
so it's just similar here!
6 is a half of 12, so the answer is 6!
hope this helps!
I say the answer is d let me know if im wrong
Answer: The equations of the tangents that pass through
y = -x- 1 and
y = 11x -25
Step-by-step explanation: The gradient of the tangent to a curve at any particular point is given by the derivative of the curve at that point. So for our curve (the parabola) we have
y= x^2 +x
Differentiating wrt x we get:
dy/dx = 2x +1
Let P (a, B) be any generic point on the curve. Then the gradient of the tangent at P is given by:
Answer:
x= 11
Step-by-step explanation:
4x+5/7 =2x-1/3
multiply both of the equation by 7 first
4x+5/7 times 7 = 2x-1/3 times 7
4x+5= (2x-1)7/3
now multiply 3 to both sides
3(4x+5)= (2x-1)7/3 times 3
3(4x+5)= (2x-1)7
now you should distribute on both sides
(4x times 3)+(5 times 3)= (2x times 7)-( 1 times 7)
12x+15= 14x-7
subtract 12x from both sides
12x-12x+15= 14x-12x-7
15= 2x-7
add 7 to both sides
15+7= 2x-7+7
22= 2x
divided both sides by 2
22/2 = 2x/2
11=x
