Since b = 3 the equation changes
5a - 10(3) = 45
5a - 30 = 45
(Add 30 to both sides)
5a = 75
Divide 5 to both sides
a = 15
Answer:
d = distance
r = rate (speed)
t = time
Step-by-step explanation:
Answer:
Range: -8 ≤ y ≤ 7.
Step-by-step explanation:
The range is the possible set of all the y-values of the function represented on the graph.
To get the set of all y-values, find the least possible y-value of the function represented on the graph on the y-axis, and the highest y-value on the y-axis.
Taking a look at the given graph, the least possible value of y is equal to or less than -8, while the highest possible y-value is equal to or less than 7.
Therefore, range is [-8, 7]. This can be represented also as: -8 ≤ y ≤ 7.
Answer:
Step-by-step explanation:
you can eliminate the radical by squaring both sides of the equation
1) expand the brackets
6(-3 - x) - 2x = 14
-18 - 6x - 2x = 14
simplify
-18 - 8x = 14
then add 18 to both sides to get the x's on there own
-8x = 32
then divide by -8
x = 32/-8
x = -4
2) multiply everything by 7x
2 + (6 x 7x) + ( 17x × 7x) = 18 x 7x
2 + 42x + 119x^2 = 126x
put everything on one side
119x^2 - 84x + 2 = 0
then use quadratic equation to solve
x = 0.024671849 or 0.6812105039
