Answer:

4n+13.

Step-by-step explanation:

n is how many weeks, he plants 4 bushes each week you multiply 4 by how many weeks pass and then add how many he already has

Write an inequality to represent the graph.
lakkis [162]

Answer:

y \leq -\frac{3}{4}x+2

y is less than or equal to negative three fourths times x plus 2

Step-by-step explanation:

step 1

Find the slope of the solid line

we have the ordered pairs

(0,2) and (4,-1)

<em>Find the slope m</em>

m=(-1-2)/(4-0)

m=-\frac{3}{4}

step 2

<em>Find the linear equation of the solid line in slope intercept form</em><em> </em>

y=mx+b

we have

m=-\frac{3}{4}

b=2 ---> the y-intercept is given

substitute

y=-\frac{3}{4}x+2

step 3

Find the inequality

Remember that the solution is the shaded area below the solid line

therefore

The inequality is

y \leq -\frac{3}{4}x+2

y is less than or equal to negative three fourths times x plus 2

Suppose measure of angle ABC equals 110, what is the measure of angle DBC?
shtirl [24]
There is no way of solving that unless we are given more information. Are ABC and DBC supplementary angles? If so, then m<DBC equals 70.

Lexi made 14 sandwiches for a group picnic. The number of ham sandwiches she made was 4 less than the twice the number of turkey
shutvik [7]

x = # of ham sandwiches

14-x = # of turkey sandwiches ( as Lexi made 14 sandwiches)


as the question said that the number of ha sandwiches are 4 less than twice number of turkey sandwiches,

x = 2 * (14-x) - 4 = 24 - 2x

3x=24

x = 8


the number of ham sandwiches is 8, and the number of turkey sandwiches is 14-8=6

Part I
We have the size of the sheet of cardboard and we'll use the variable "x" to represent the length of the cuts. For any given cut, the available distance is reduced by twice the length of the cut. So we can create the following equations for length, width, and height.
width:  w = 12 - 2x
length: l = 18 - 2x
height: h = x

Part II
v = l * w * h
v = (18 - 2x)(12 - 2x)x
v = (216 - 36x - 24x + 4x^2)x
v = (216 - 60x + 4x^2)x
v = 216x - 60x^2 + 4x^3
v = 4x^3 - 60x^2 + 216x

Part III
The length of the cut has to be greater than 0 and less than half the length of the smallest dimension of the cardboard (after all, there has to be something left over after cutting out the corners). So 0 < x < 6

Let's try to figure out an x that gives a volume of 224 in^3. Since this is high school math, it's unlikely that you've been taught how to handle cubic equations, so let's instead look at integer values of x. If we use a value of 1, we get a volume of:
v = 4x^3 - 60x^2 + 216x
v = 4*1^3 - 60*1^2 + 216*1
v = 4*1 - 60*1 + 216
v = 4 - 60 + 216
v = 160

Too small, so let's try 2.
v = 4x^3 - 60x^2 + 216x
v = 4*2^3 - 60*2^2 + 216*2
v = 4*8 - 60*4 + 216*2
v = 32 - 240 + 432
v = 224

And that's the desired volume.
So let's choose a value of x=2.
Reason?
It meets the inequality of 0 < x < 6 and it also gives the desired volume of 224 cubic inches.
