Answer:

  B

Step-by-step explanation:

The given equation is in slope-intercept form:

  y = mx + b

where the slope is m = -3 and the y-intercept is b = +2.

So, the graph will have a slope of ...

  "rise"/"run" = -3 = -3/1

and will cross the y-axis at y=2.

Graphs A and B cross the y-axis in the right place, but only Graph B has a negative "rise" a x increases.

harkovskaia [24]
The corresponding line segment is B. because the slope does not change. A dilation will always have the effect of shrinking or even stretching the line segment by the factor of n. That is why the length will nx and the slope is m.

Hope this helped.

Which expression represents the fourth term in the binomial expansion of (e + 2f)10?
yan [13]

The fourth term of the binomial expansion (e+2f)^{10} can be calculated using the formula for (i+1)-th term of the binomial expansion:

T_{i+1}=C_{10}^i\cdot e^{10-i}\cdot (2f)^i.

In order to find term T_4, determine that

i+1=4\Rightarrow i=3.

Now

T_4=C_{10}^3\cdot e^{10-3}\cdot (2f)^3=C_{10}^3\cdot e^7\cdot (2f)^3.

Answer: correct choice is A

Find the domain of the following graph:
sukhopar [10]

Answer:

-7

Step-by-step explanation:

The domain is the set of all x-values. We can find the domain by finding the left boundary of the graph (the furthest left x-value) and then the right boundary (the furthest right x value).

The furthest left x-value is -7. Notice it has a large open circle here that is not filled in. This means the function does not include -7 but includes numbers very close to it like-6.999999..... We sue use an inequality sign without an equal to to write -7. x >-7.

The furthest right x value is 9. It has a closed circle or "filled in" circle so we write with an equal to sign. x\leq 9.

We combine the two into -7.

What should your units on your base area calculations be, and why? How is this different from the units on your volume calculati
horsena [70]

Answer:

For area, square unit is used as the area is calculated using two dimensions length and breadth.

For volume, cubic unit is used as the volume is calculated using three dimensions length, breadth and height.

Step-by-step explanation:

Area refers to the space occupied by a two dimensional flat object in a plane. For area, square unit is used as the area is calculated using two dimensions length and breadth.

Volume is defined as the space occupied by the three-dimensional object. For volume, cubic unit is used as the volume is calculated using three dimensions length, breadth and height.
