Answer:
d) not proportional
Step-by-step explanation:
the rate of change between the first two pairs of x-and-y values is 12/3, between the second pair it is 21/3, and 15/3 between the last pair
4, 7, and 5 are all different values so there is not one constant of proportionality
Answer:
y = 126.43
Step-by-step explanation:
Essentially what you have is the Cosine(50)
Cos(50) = adjacent / hypotenuse
adjacent = 122
hypotenuse = ?? = y
Solve
Cos(50) = 122/y Multiply both sides by y
y*cos(50) = 122 Divide by cos(50)
y = 122 / cos(50) Find the value of cos(50)
y = 122 / 0.96497 Divide
y = 126.43
The following statements is true:
C. 0 ÷ 15 = 0
A, B, and D are not true because:
15 - 0 = 15
15 + 0 = 15
15 ÷ 0 = undefined.
Your final answer is C. 0 ÷ 15 = 0.
For this i will not give the answer but i will guide you one how to do it
first of all if the line is perependicular to -1/5x-1/8 that mean its the opposite and swicht signs. so since jt only effects the slope the slpoe for the other equation will be from -1/5 to 5 since we flipped the fraction and flipped the sign. next it also says that the new line k has to pass through (0,0) that would mean since (x,y) equals (0,0) we would have to plug the x and y which is the two zeros giving us and equation like this
0=5(0)+b
if we make in it slope intercept form it would have to be y=mx+b
then if you slove for b you will put it into the equation
y=5x+b
text/chat me if you dont understand or you need the answer.
hope this helps
