F(x) = 3x-6
add 6 to each side
6=3x
dived each side by 3
2=x
Answer:
z = - .5
Step-by-step explanation:
z = (x - μ)/ σ
z = 56 - 60/8 = -.5
The answer to that equation is that it has 8 sides
We need to do a system of equations here.
x + y = 275 (if you travel <em>x</em> km by bike and <em>y </em>km by bus, then you travel 275 km as given in the problem)
y = x + 55 (the problem stated that they were bussed (y) the amount they biked plus 55 more km (x + 55))
The second equation is already solved for y. So, we can plug it in to the first equation.
x + (x + 55) = 275
2x + 55 = 275 [combine x terms]
2x = 220 [subtract 55 from both sides]
x = 110 [divide by 2 to isolate x and solve for it]
Now we know that x is 110, the distance they traveled by bike.
And that's what we needed to answer the problem!
Answer:
(B)Enlarge by scale factor of 3 about the origin. Then translate 1 right.
Step-by-step explanation:
For the end point (3,4)
- If we enlarge (3,4) by a scale factor of 3 about the origin, we have: (9,12)
- If we then translate 1 right, we have :(10,12)
Similarly for the end point (4,5):
- If we enlarge (4,5) by a scale factor of 3 about the origin, we have: (12,15)
- If we then translate 1 right, we have :(13,15)
The correct option is B.
