Two numbers multiply to be -40 and add to be 3. What are the numbers?

Answers

Answer:

The numbers are (x,y)=(-5,8) or (8,-5)

Step-by-step explanation:

Let two numbers be x and y,

We have,

x+y=3

x=3-y---(i)

Now,

xy=-40

(3-y)y=-40 [From (i)]

3y-y^2=-40

y^2-3y-40=0

Factoring,

(y + 5) (y - 8)=0

Either,

y+5=0        or,      y-8=0

y=-5                      y=8

When y=-5,

x=3-y

3--5

3+5

8

When y=8,

x=3-y

Carina drinks 96 ounces of water in an 8-hour workday. Which expression can be used to calculate the number of ounces of water that Carina drinks each hour?

Answers

Divide 96 by 8 = 12
12 x 8 = 96
per hour she drinks 12 ounces of water
divide 96 by 8, then you get 12, but it would be 12oz, so on average, she consumes about 1.5 cups of water each hour of an 8-hour workday.

Answer:

1) [tex]y-6=-\frac{2}{3} (x-1)[/tex] and 2) [tex]y=-\frac{2}{3} x+\frac{20}{3}[/tex]

Step-by-step explanation:

Ikr the bots are annoying.

Point-slope form is written as: [tex]y-y_1=m(x-x_1)[/tex]

Slope intercept form is written as: [tex]y=mx+b[/tex]

We also need to find the slope before putting it in this form, which can be done by [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

1) Points given are (1,6) and (-2,8)

Slope: [tex]m=\frac{8-6}{-2-1} =-\frac{2}{3}[/tex]

You can choose either of the two points to put into the formula. I just chose (1,6)

Answer: [tex]y-6=-\frac{2}{3} (x-1)[/tex]

2) Same points as before and we have the same slope as before. All we need is to find the y intercept which is our b in the equation. You can easily do this by plugging in a point and solving for b. I will choose point (1,6) again.

[tex]6=-\frac{2}{3} (1)+b[/tex]

[tex]6=-\frac{2}{3} +b[/tex]

[tex]6+\frac{2}{3}=-\frac{2}{3} +\frac{2}{3} +b[/tex]

[tex]b=6+\frac{2}{3}=\frac{20}{3}[/tex]

Answer: [tex]y=-\frac{2}{3} x+\frac{20}{3}[/tex]

0=4a+2b+c

subtract

Find a, R, and T.

Answers

a = 4, R = 147, T = 33

Step-by-step explanation:

find a

a/(a + 7) = (16/3)/(44/3)

a/(a + 7) = 16/44

44a = 16a + 112

44a - 16a = 112

28a = 112

a = 112/28

a = 4

find R

2x + 5 = 3x - 9

5 + 9 = 3x - 2x

14 = x

m ∠R = 180° - (2x + 5)

= 180 - (28 + 5)

= 180 - 33

= 147°

find T

m ∠T = 3x - 9

= 3(14) - 9

= 42 - 9

= 33°
