It’s 14

3(4) + 2
12+2 = 14

You have to substitute x by 4

It would be 14 because you are multiplying 3•4 percent high is 12 and then adding 2 which would make it 14

Y = x² + 4x + 8 Sketch the graph of each function be sure to show your table of values

kherson [118]

Answer:

see attachment

Step-by-step explanation:

We want to sketch the graph of

$y = {x}^{2} + 4x + 8$

We want to use tables so we choose some few points and plot.

When x=-6,

y=(-6)²+4(-6)+8=20

When x=-4,

y=(-4)²+4(-4)+8=8

When x=0,

y=(-2)²+4(-2)+8=4

When x=0,

y=(0)²+4(0)+8=8

When x=2,

y=(2)²+4(2)+8=20

The table and graph are shown in attachment.

If angle ABC is one degree less than three times angle ABD and angle DBC=47 find each measure

Contact [7]

It has not been indicated whether the figure in the questions is a triangle or a quadrilateral. Irrespective of the shape, this can be solved. The two possible shapes and angles have been indicated in the attached image.

Now, from the information given we can infer that there is a line BD that cuts angle ABC in two parts: angle ABD and angle DBC

⇒ Angle ABC = Angle ABD + Angle DBC

Also, we know that angle ABC is 1 degree less than 3 times the angle ABD, and that angle DBC is 47 degree

Let angle ABD be x

⇒ Angle ABC = 3x-1

Also, Angle ABC = Angle ABD + Angle DBC

Substituting the values in the above equations

⇒ 3x-1 = x+47

⇒ 2x = 48

⇒ x = 24

So angle ABD = 24 degree, and angle ABC = 3(24)-1 = 71-1 = 71 degree

George has 36 cupcakes he has eight friends coming over to the party if he shares the cupcakes evenly with himself and all the g

Bogdan [553]

Answer:

Each person would get 4 cup cakes if all 8 friends attend the party.

Each person would get 12 cup cakes when 6 friends not attended the party.

Step-by-step explanation:

Given:

Total Number of cup cakes = 36

Number of friends coming to party = 8

Total number of people cakes need to distributed including George = 9

We need to find the number of cup cakes each person would get;

Solution:

Now we can say that;

number of cup cakes each person would get is equal to Total Number of cup cakes divided by Total number of people cakes need to distributed including George.

framing in equation form we get;

number of cup cakes each person would get = $\frac{36}{9}=4$

Hence Each person would get 4 cup cakes if all 8 friends attend the party.

Now Given:

Number of friends not attended the party = 6

So we can say that;

Total number of people cakes need to distributed including George = 9 - 6 = 3

So we can say that;

number of cup cakes each person would get = $\frac{36}{3} =12$

Hence Each person would get 12 cup cakes when 6 friends not attended the party.
