Answer:
-x^2+4x+6
Step-by-step explanation:
f(x) = 4x+1
g(x) = x^2 - 5
(f-g) (x) = 4x+1 - ( x^2 - 5)
Distribute the minus sign
= 4x+1 - x^2 +5
Combine like terms
= -x^2+4x+6
Answer:
B. (3,0)(0 ,-6)
Step-by-step explanation:
What is intercept.?
Intercept are those points where a given line cuts across a given axis.
So for the equation y = 2x - 6
To find the intercept we will bear in mind that we are looking for two points.
The point where the line cuts both the x axis and the y axis .
And to determine that, we will set both x and y to be equal to zero and then solve for both.
So let x = 0
Y = 2x -6
Y = 2(0) -6
Y = -6
One point = (0 ,-6)
Let y = 0
Y = 2x -6
0 = 2x -6
6 = 2x
X = 3
One point = (3,0)
The two points are
(3,0)(0 ,-6)
Answer:
x = 20
Step-by-step explanation:
Write and solve an equation of ratios, as follows:
1 3/4 14
------------ = --------
2 1/2 x
where x is the unknown number.
Converting the mixed numbers to improper fractions, we get:
7/4 14
------ = -----
5/2 x
Here there are two numerators and two denominators. Multiplying all four quantities by 4 will remove some of the fractions:
7 56
------ = -------
10 4x
Cross multiplying, we get:
28 x = 560, or x = 20
Distribute the .15 on the right side to get:
20 + .5x + 3 + .075x
Then, combine like terms (add numbers together and add x terms together):
.575x + 23
...and that's your final answer!
