Answer:
The first one is 75 and the second one is 81
Step-by-step explanation:
put 187.5 into calculator then divide it by the bottom number/denominator in this case 2.5 and then you get 75
put 303.75 into calculator then divide it by the denominator or 3.75 and you get an answer of 81
so 81 miles per hour
I really hope this helps!
Answer:
120 different outcomes, D. (PLZ GIVE BRANLIEST)
Step-by-step explanation:
The slope of this line is
-5 - 3 -8
m = ----------- = ----------
4-(-1) 5
Then use the point-slope format to find the equation of this line.
y-3 = (-8/5)(x-(-1)), or y - 3 = (-8/5)( x + 1) (answer)
This could be re-written in other forms, such as the slope-intercept form.
Answer:
x = 1 and vertex = (1, - 7 )
Step-by-step explanation:
Given a quadratic function in standard form
y = ax² + bx + c ( a ≠ 0 )
The the equation of the axis of symmetry which is also the x- coordinate of the vertex is
x = - 
y = 4x² - 8x - 3 ← is in standard form
with a = 4, b = - 8 , then
x = - 
= 1
That is equation of axis of symmetry is x = 1
Substitute x = 1 into the function for y- coordinate of vertex
y = 4(1)² - 8(1) - 3 = 4 - 8 - 3 = - 7
vertex = (1, - 7 )
That is very easy. 900 x 5. If you were rounding.
