Step-by-step explanation:
First thing first, let find the x value of where P and Q both meet y=5, we know that y=5, and y=2x^2+7x-4, so using transitive law,
Now, to find the gradient of the curve let take the derivative of both sides
Plug in -9/2, let call that point P
Plug in 1, let call that point Q
So the gradient of the curve at point P (-9/2,5) is -11
The gradient of the curve at point Q (1,5) is 11.
Answer:
The solution is the area x < 67/5
Step-by-step explanation:
Perform the indicated multiplication. We get:
9x - 27 < 4x + 40
Combining like terms results in:
5x < 67
Then the solution is the area x < 67/5
There are 14 erasers in the jar all together, and 10 of them are not pink.
The probability of picking a not-pink one is
10/14 or 5/7 or 0.0.7143... or 71.43% .
Answer:
<A =21
<B = 84
<c = 75
Step-by-step explanation:
<A =x
<B = 4x
<C =5x-30
The sum of A+B+C = 180
x+ 4x + 5x-30 = 180
Combine like terms
10x -30 = 180
Add 30 to each side
10x-30+30 = 180+30
10x = 210
Divide by 10
10x/10 = 210/10
x= 21
Since x =21 we can find the value of the angles
Substituting x into the equations for angles A, B and C
<A =21
<B = 4x = 4*21 = 84
<C = 5x-30 = 5*21-30 = 105-30 = 75
Answer:
find out how many units higher g(x) is compared to f(x).
g(x) is 3 units higher than f(x)
Since the graph is 3 units higher, the value of k must be 3.
