</span>(2x^2 - 5x + 4) Original Mathematical Expression
[2(7)^2 - 5(7) + 4] Plugging the value of x, 7 into expression.
There are parentheses, so that means we have to work in them.
There are exponents, so we have to do those first.
[2(49) - 5(7) +4] Exponents.
There is multiplication, that we can do, so we do that left to right.
[98 - 35 + 4] Multiplication.
There is no division.
There is addition and subtraction, so we do those left to right.
[63 + 4] Subtraction.
67 Addition.
Final Answer: 67
Answer:
4 because 5 times 4 is 20 and 3 times 4 is 12
The example of exponential growth is: <span>c. y=0.5(1.5)x </span>
The function y = ab˟ is a can only be growth function if the value b>1. And if 0<b<1 it will decay. Therefore, the only correct value that fits the definition of exponential growth is option C.
Answer:
0
Step-by-step explanation:
using the values of a,b, and c, the discriminant equals 0.
Answer:
Step-by-step explanation:
We can write the equation using the point and the slope .
Formula we need to use is the point slope formula
Which is given by
Y-y1= m(X-x1)
Here given that (x1,y1)=(1,-1) and m = -3
x1= 1
y1 = -1
so equation is
Y-(-1) = -3 (x-1)
Distribute the slope
y+1 = -3x+3
y= -3x+3-1
y = -3x + 2
So the equation is
y =-3x +2
