Answer: 0 < x < 5.6
Step-by-step explanation:
The sides of triangle:
Any two sides added together have to be larger than the third side
So:
2.8 - 2.8 < x < 2.8 + 2.8
0 < x < 5.6
Answer:
Option C is correct.
Bobby has $300 in the yearbook fund and earns $13.50 for each yearbook sold.
Step-by-step explanation:
Slope intercept form: An equation of line is given by:
......[1] where m is the slope and b is the y-intercept
Given the linear equation: 
Here, x represents the yearbook sold.
On comparing with the equation [1] we have;
m = $13.50
b =300
therefore, the best scenario best matches the linear relationship is:
Bobby has $300 in the yearbook fund and earns $13.50 for each yearbook sold.
Each numbers (except 0) to zero power are equal 1. So

assuming
Answer:
Step-by-step explanation:
The usual equation used for the vertical component of ballistic motion is ...
h(t) = -16t² +v₀t +h₀
where v₀ is the initial upward velocity, and h₀ is the initial height. Units of distance are feet, and units of time are seconds.
Your problem statement gives ...
v₀ = 64 ft/s
h₀ = 8 ft
so the equation of height is ...
h(t) = -16t² +64t +8
__
For quadratic ax² +bx +c, the axis of symmetry is x=-b/(2a). Then the axis of symmetry of the height equation is ...
t = -64/(2(-16)) = 2
The object will reach its maximum height after 2 seconds.
The height at that time will be ...
h(2) = -16(2²) +64(2) +8 = 72
The maximum height will be 72 feet.
Answer:
y=-3x-2
Step-by-step explanation:
step 1- find the slope
parallel to means same slope, so look at y+3x=4, its not in the correct slope form so we subtract both sides by 3x to get y=-3x+4, the slope is the coefficient of x which is -3. Slope equals 3
step 2- use the point slope form which is y-y1=m(x-x1)
and substitute in the numbers (only substitute y1,x1, and m)
m is the slope which we found to equal -3
x1 and y1 are the points that they gave us (-2,4) are (x1,y1)
x1=-2
y1=4
step 3- substitute
y-y1=m(x-x1)
y-4=-3(x-(-2))
simplifies to y-4=-3x-6
add 4 to both sides to get y=-3x-2
