Answers

Answer:

Step-by-step explanation:

(-4 , -7) ; slope = (2/3)

y -y1 =m(x-x1)

[tex]y -[-7]=\frac{2}{3}(x-[4])\\\\y+7 = \frac{2}{3}(x+4)\\\\y+7=\frac{2}{3}x+4*\frac{2}{3}\\\\y +7 = \frac{2}{3}x+\frac{8}{3}\\\\y=\frac{2}{3}x+\frac{8}{3}-7\\\\y=\frac{2}{3}x+\frac{8}{3}-\frac{7*3}{1*3}\\\\y=\frac{2}{3}x+\frac{8}{3}-\frac{21}{3}\\\\y=\frac{2}{3}x-\frac{13}{3}[/tex]

— 3х + 9y = — 21
— 3х +8y = -18
find the solution by system of equations

Answers

Answer:

x=-2,y=-3

Step-by-step explanation:

x=7+3x

-3x+8y=-18

-21-y=-18

x=7+3x

y=-3

x=7+3x

x=-2

y=-3

Answer:

x = -2

y = -3

Step-by-step explanation:

There are three methods for solving system of equations: elimination, substitution, and graphing. In this case elimination would be the best method since you have -3x for both equations. When solving by elimination, your goal is to eliminate one of the variables, in this case we will eliminate x. Subtract the bottom equation from the top (it is important to remember here that the negative will distribute to the entire equation).

-3х + 9y = -21

- (- 3х +8y = -18)

_____________

y = -3

Now plug this y-value in to either equation and solve for x

-3х + 9y = -21

-3х + 9(-3) = -21

-3x - 27 = -21

-3x = 6

x = -2

Check your answer by plugging both values in to the second equation

- 3х +8y = -18

- 3(-2) +8(-3) = -18

6 - 24 = -18

-18 = -18

Step-by-step explanation:

To find the volume, you have to solve the width x length x height.

So, 1 of the containers is 20(W) x 15(L) x 10(H) which equals to a volume of 3,000.Then we have another container with the same dimensions. That means we will add 3,000 because it's the same. 3,000 + 3,000 = 6,000

find angle at bottom corner

arctan(20/80) = about 14.04624 degrees

cos(14.04624) = 20(sqrt17) / (80+a)

solve for a: --> a = 5 units

[tex]3h+\sqrt{2}=\sqrt{5}\\ \\ 3h=\sqrt{5}-\sqrt{2}\\ \\ h=\frac{\sqrt{5}-\sqrt{2}}{3}[/tex]

Question:

3h+sqrt.2=sqrt.5

Answer:

h=sqrt.5-sqrt.2/3 (the very last option)

Method:

You have to get h on its own so you start by subtracting sqrt.2 on both sides, you subtract because you have to reverse the original symbol (+ becomes -, ^2 becomes sqrt., * becomes /, and the other way around, etc.), once you do that you have to divide by 3 on both sides and you get your answer.

Visual:

1. 3h+sqrt.2=sqrt.5
-sqrt.2 -sqrt.2

A girl weight increased by 12% between her tenth and four teen birthdays . If she weighed 45kg on her tenth birthday. What did she weigh on her fourteenth birthday

Answers

Ok so the first thing you are going to do is chang the percentage into a decimal. 12 percent would change into 0.12, because in order to change a percentage into a decimal you move the decimal two places to the left. Next you would multiply 0.12 by 45 which gives you 5.4. But we are not done yet. By multiplying 0.12 x 45 we find how much weight she has gained. So our next and final step should be add 5.4 to 45 which gives us 50.4. Therefore your answer should be 50.4kg
