Answer:
Step-by-step explanation:
Quadratic function is a function that can be described by an equation of the form fx = ax2 + bx + c, where a ≠ 0.
Example:
1. Use the graph of y = x2 + x - 6 to solve x2 + x - 6 = 0.
2. Use the graph of y = -x2 + 4 to solve -x2 + 4 = 0.
3. Use the graph of y = x2 -2x + 1 to solve x2 -2x + 1.

The graph intercepts y at -3 and the slope is -1
Answer:
It's the 3rd answer. y = -x - 3
Step-by-step explanation:
Which of the lines below is parallel to a line with a slope of 3 and a y-intercept at (0, 3)?
line AB
line CD
line FG
line HJ
Answer:
[tex]\displaystyle line\:HJ[/tex]
Step-by-step explanation:
[tex]\displaystyle y = 3x + 3[/tex]
The descryption gives you the above Slope-Intercept Equation. Parallel equations have SIMILAR RATE OF CHANGES [SLOPES], therefore [tex]\displaystyle 3[/tex] remains as is, and perfourming [tex]\displaystyle \frac{rise}{run},[/tex] will give you that answer.
I am joyous to assist you at any time.

Need answer simplify -2/5+4/3=
Answer:
The answer should be 14/15.
Step-by-step explanation:
The answer is 14/15 because -2/5 and 4/3 with a common denominator turns into -6/15 and 20/15.
Then you add both of them together.
-6/15 + 20/15 = 14/15

the difference of 2x and 15 is less than or equal to the sum of 4x and 17
Step-by-step explanation:
the difference of 2x and 15 is less than or equal to the
sum of 4x and 17
i.e.,
2x - 15 < 4x + 17
if you want to find ahead then
2x - 15 = 4x + 17
2x - 4x = 17 + 15
- 2x = 32
x = - 32/2
x = - 2

Answer:
[tex]\huge\boxed{\sf 6.25 \ g}[/tex]
Step-by-step explanation:
After every Half life , Half of the mass is left.
After 1st Half life = 100 g / 2 = 50 g
After 2nd Half life = 50 / 2 = 25 g
After 3rd Half life = 25 / 2 = 12.5 g

A cyclist travels 4miles in 15 minutes. What is her average speed in mph?
Answer:
5
Step-by-step explanation:
Hence, the average speed to the cyclist is 16mph.
What is speed?Speed is defined as the rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude.
How to solve?We know,
distance covered = 4 miles
time taken = 15 minutes = [tex]\frac{1}{4}[/tex]hours
speed = [tex]\frac{4}{\frac{1}{4} }[/tex] = 16
Hence, speed is 16.
