Answer:

Question 3

C. y-9 =1/2(x-1)

Question 4

D. y+5 =3(x+2)

Step-by-step explanation:

Question 3:

Equation of line in point slope form is given as:

y-y_1 =m(x-x_1)

Plug m = 1/2, x_1 = 1, \:y_1 = 9 in the above equation, we find:

y-9 =1/2(x-1)

This is the required equation of the line.

Question 4:

Equation of line in point slope form is given as:

y-y_1 =m(x-x_1)

Plug m = 3, x_1 = - 2, \:y_1 = - 5 in the above equation, we find:

y-(-5) =3[x-(-2)]

y+5 =3(x+2)

This is the required equation of the line.

F(x) = 4x - 1
Natasha2012 [34]

Answer:

D

Step-by-step explanation:

Find (f + g)(x) then evaluate (f + g)(9)

(f + g)(x) = f(x) + g(x)

= 4x - 1 + x² - 2 = x² + 4x - 3

Now substitute x = 9 into the expression

(f + g)(9) = 9² + 4(9) - 3 = 81 + 36 - 3 = 114 → D

Step-by-step explanation:

43. P, U

44. 7

53. Airplanes can be traveling on different planes, one plane above the other. Cars on the same intersection are on the same plane.

55

a. You can choose (4 * 3 * 2)/(3 * 2) = 4 groups of 3 points in which order does not matter.

One of those combinations does not have K, so 3 combinations of the 4 have K.

p = 3/4

b. p = 1 since any three points are always coplanar.

Elina [12.6K]

Answer:

<u>30 gallons solution 4% and 10 gallons solution 8%</u>

Step-by-step explanation:

<h3>x•4%+y•8%=40•5% </h3>

<em><u>4x+8y=40•5 and x+y=40</u></em>

x=40-y

4(40-y)+8y=200

160-4y+8y=200

4y=200-160

4y=40 => y=10 (gallons solution 8%)

=> x=40-10=30 (gallons solution 4%)

30 gallons solution 4% and 10 gallons solution 8%
