What we are going to do with this problem is combine all the like terms. 
so to begin, we notice that there are two numbers with a^2 involved, and two numbers with an a.

thus:
8a^{2}+(-3a^{2} is going to equal 5a^{2} because adding a negative is just like subtracting.

then we move on to (6a)-(2a) giving us 4a
5 is the only term that stays the same because there are no other similar terms.
last but not least, put the equation together!

answer: 5a^{2}+4a+5

I need help plsssssssss
liq [111]

Answer:

A

Step-by-step explanation:

If you follow the dotted lines and bring all the lines together,

angle8 = angle4 (corresponding angles)

angle8 = angle5 (vertically opposite angles)

angle5 = angle1 (corresponding angles)

Therefore, angle8 is basically the same as angles 1 and 4

Thus,

127+127=254

What is the equation that represents the line that passes through the point (2,6) and has a slope of -5?
tiny-mole [99]

Answer:

y = - 5x + 16

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 5, thus

y = - 5x + c ← is the partial equation of the line

To find c substitute (2, 6) into the partial equation

6 = - 10 + c ⇒ c = 6 + 10 = 16

y = - 5x + 16 ← equation of line

Approximately 32,400 citizens of the country died in 2015. Express the toll in deaths per day
Zigmanuir [339]

There is 90 deaths per day.

First it tells us 32,400 people died in 2015, which also mean that many people died that year.

We have to find the number of people died each month first.

32,400÷12 because 12 is the total number of months in a year.

2700 people died in a month, not we need to find how many people died each day so we divided it by 30 and we get

90 deaths per day.

A quadratic equation is shown:
insens350 [35]

Answer:

<em>The correct answer is the first option</em>

Step-by-step explanation:

<u>Quadratic Equation</u>

The standard form of a quadratic equation is

ax^2+bx+c=0

Sometimes we need to change the expression of the same equation to the form

(x-p)^2=q

To accomplish that change, we usually modify the left-hand expression to make it look like the square of a binomial.

The given quadratic equation is

x^2-14x+41=0

Recall the square of a binomial is

(x-p)^2=x^2-2px+p^2

The first term is already present. The second term gives us the value of p:

-2px=-14x

Solving

p=7

Now we need to produce the third term p^2=49. We only have 41, thus we need to add 8 to both sides of the equation:

x^2-14x+41+8=0+8

The correct answer is the first option
