36/9+2/9 fraction adding!!!

Mathematics

Answer: 38/9

Step-by-step explanation: Because the fractions presented already have common denominators, the only thing you need to do in order to solve the problem is add the numerators. 36+2= 38, and you keep your denominator the same when adding fractions (when they are the same).

Alchen [17]

Answer:

64.9  billions

Step-by-step explanation:

Change the points to match the definition given for the representation of the years, the first point (1994,51.7) becomes (0,51.7) and the second (1998,60.5) now is (4,60.5).

Find the slope m of the linear function using the two points and the formula:

m=\frac{y_2-y_1}{x_2-x_1} \\m=\frac{60.5-51.7}{4-0} \\m=\frac{8.8}{4} =2.2

Use the point-slope form of the linear equation to find the slope-intercept form:

y-y_1=m(x-x_1) point-slope form

y=mx+b slope-intercept form

y-y_1=m(x-x_1)\\y-51.7=2.2(x-0)\\y-51.7=2.2x\\y=2.2x+51.7

2000 is represented by x=6, using the slope-intercept form solve for y (egg production in billions):

y=2.2x+51.7\\y=2.2(6)+51.7\\y=13.2+51.7\\y=64.9 billions

Find (−3d2+10d−8)−(7d2−d−6). The difference is .
katovenus [111]

-10d^2 + 11d - 2

To find this, distribute the - to 7d^2 - d - 6.

This will give you a new equation of:

-3d^2 + 10d - 8 -7d^2 + d + 6

Combine like terms to get the answer above.

Hope this helps!

Factor the binomial.<br> 9x^4-64
kap26 [50]

Answer:

The answer is the first one

Step-by-step explanation:

This is a difference of squares, meaning the first term is a perfect square, and the second term would be a perfect square if it were not negative. To factor it, find the square root of both the first an second term, the square root of 9x^4 is 3x^2 and the square root of 64 is 8. Put both of those numbers into 2 separate sets of parenthesis and one set will have + in between and the other will have -. It will look like the first option
