(x2+3x+2)+(3x2–x+1) Use algebra to find the sum

Answers

Answer: -2x²+2x+3

Step-by-step explanation:

Factoring -2x2+2x+3

The first term is, -2x2 its coefficient is -2 .

The middle term is, +2x its coefficient is 2 .

The last term, "the constant", is +3

Step-1 : Multiply the coefficient of the first term by the constant -2 • 3 = -6

Step-2 : Find two factors of -6 whose sum equals the coefficient of the middle term, which is 2 .

-6 + 1 = -5

-3 + 2 = -1

-2 + 3 = 1

-1 + 6 = 5

Observation : No two such factors can be found !!

Conclusion : Trinomial can not be factored

d. y<3x-9

Answers

Answer:

simplify within parenthesis ​

Answers

Answer:

First Space: 49

Second Space: 33

Third Space:-99

Fourth Space: -99

Fifth Space: 10

Sixth Space: -89

Step-by-step explanation:

First Space: for the first space you would do -7 times -7 because it is squared so you would get 49 because a negative and a negative and a negative make a positive.

Second Space: For the second space you have to do 49-16 because you already found the first space and the answer would be 33.

Third Space: For the third space you would do the answer you got from the second space which is 33 and multiply by -3 because -3 is outside the brackets. The answer would be -99.

Fourth Space: You would just put the same thing as the third space and put -99.

Fifth space: To find the fifth space you have to do 4 ÷ 2/5. To find this part you have to do 4 times the reciprocal (when you flip the fraction) and you would get 4 times 5/2. Then you can cross the denominator (bottom of the fraction) and make the 4 a 2 because 4 ÷ 2=2. Next you do 2 times 5 and get 10 as a answer.

Sixth Space: For the final answer you would use the fourth and fifth space. You would do -99+10 which is -89.

Hopefully this helps :)

5. Michel wants to buy his mother handmade chocolates for Mother’s Day. He has $15.00 to spend. The price of each type of chocolate is given below.
Fudge centres: $0.60 Nut clusters: $0.75 Truffles: $0.80

Michel has $15.00. How many of each type of chocolate can he buy if buys only one type? Show your work. *Hint: create an equation for each type*

Fudge centres: Nut clusters: Truffles:

Michel decides to buy all three types of chocolates, instead of choosing just one type. If Michel buys the same number of all three types, how many can he buy and stay within his budget? Show your work

Answers

Answer:

25 fudge centres, 20 nut clusters, 18 truffles, 6 of each type of chocolate

Step-by-step explanation:

Michel has a total of $15.00

So, if he only has to buy one type, we just divide the total amount by the price, like this:

[tex]\frac{15.00}{0.60}[/tex] = 25 fudge centres

[tex]\frac{15.00}{0.75}[/tex] = 20 nut clusters

[tex]\frac{15.00}{0.80}[/tex] = 18.75, so we round down = 18 truffles

If he buys the same of number of each type, we know that:

0.60x + 0.75x + 0.80x ≤ $15.00

2.15x ≤ 15.00

x ≤ 6.977...

This means that Michel can only buy 6 of each type of chocolate.

Answer:

If he buys only one type, he can buy 25 fudge centers OR 20 nut clusters OR 18 truffles.

The equations you can write to solve those are:

0.6f = 15

0.75n = 15

0.8t = 15

If he buys an equal number of each then

0.6f + 0.75n + 0.8t = 15

and

f = n = t

He can buy 6 of each without going over his budget.

In the diagram, DEC is a
of ABC across line m.

A. rotation
B. glide reflection
C. translation
D. reflection

Answers

Step-by-step explanation:

This is a reflection. A reflection is a transformation involving two shapes looking the same by "bouncing it off a line without coming back.( meaning a reflection goes some where else not to it original poistion.)

Others reason why Why?

Line m is perpendicular to Line c.

B and E are equidistant from c that BC=CE.

Why the others are wrong.

While you could rotate this triangle 180 degrees, the transformation occurs about a line not a point. So using a rotation is wrong.

A translation doesnt occur about a line.

A guide reflection doesnt work since the transformations are already mapped correctly if you do the reflection. It doesnt need a translation.

Answers

Answer:

The answer should be 75 if i did the math right

Answer:

Step-by-step explanation:

You have to add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.

So in this case it would be:

46+56+64+64+72+76+77+82+94+96+99.

And the answer for the first step is: 826.

Next Step!

826 will have to be divided by 11.

Because there are 11 numbers that had to be added.

So 826÷11=75.
