Answer:
Step-by-step explanation:
Depends on what you mean by multiplying by - 1. I assume you are not going to multiply the y or f(x) term by - 1.
If that is so, take an example. Suppose you have a graph that is y=x^2
That's a parabola that opens upwards and it has a line going through its focus which is a point on the +y axis.
When you multiply the right hand side by - 1, the graph you get will be y = - x^2.
That opens downward and the focus is on the - y axis.
That means that the effect of the graph is that it flips over the x axis, which I think is the third answer.
Answer:
Given the ratio for dinosaur stamps to airplane stamp, the correct ratio is 18 : 12
Step-by-step explanation:
Dinosaur stamps = 18
Airplane stamps = 12

ratio of dinosaur stamps to airplane stamps = 12 to 18
Correct ratio:
ratio of dinosaur stamps to airplane stamps = 18 : 12
= 18/12
Answer:
infinite solutions
Step-by-step explanation:
4x+4(3x+7) = 8(2x-3) +52
Distribute
4x+12x+28 = 16x-24+52
Combine like terms
16x+28 = 16x +28
Subtract 16x from each side
16x-16x+28 = 16x-16x +28
28=28
This is true, so there are infinite solutions
Answer:
B) Brand 2
Step-by-step explanation:
Brand 1: $10.68 ÷ 12 = 0.89
Brand 2: $9.44 ÷ 16 = 0.59
Brand 3: $15.30 ÷ 18 = 0.85
Brand 4: $21.84 ÷ 24 = 0.91
Brand 5: $20.40 ÷ 30 = 0.68
Least cost per packet is of Brand 2
Answer:
Step-by-step explanation:
According to the remainder theorem, if a function f(x) is divided by (x-a), then the remainder is defined by f(a).
It is given that 
has a remainder of 14.
Here, the function f(x) is divided by (x+6). So, on comparing (x+6) and (x-a), we get
So, by remainder theorem, remainder of is f(-6).
Since the remainder is 14, therefore
Therefore, the answer for first blank is -6 and for second blank is 14, i.e., .
