The x-coordinate in the solution of the system of equations  y = -2/3x and 4x - 9y = -40 is -4

<h3><u>Solution:</u></h3>

<em><u>Given that system of equations are:</u></em>

y = \frac{-2}{3}x  ------- eqn 1

4x - 9y=-40 ------ eqn 2

We have to solve the above given system of equations and find the x - coordinate

<em><u>Substitute eqn 1 in eqn 2 and solve for "x"</u></em>

4x - 9(\frac{-2}{3}x) = -40\\\\4x + \frac{18x}{3} = -40\\\\12x + 18x = -120\\\\30x = -120\\\\x = \frac{-120}{30} = -4

x = -4

Thus the x-coordinate in the solution of the system of equations is -4

Last week, it rained g inches. This week, the amount of rain decreased by 5%. Which expressions represent the amount of rain tha
dybincka [34]

Answer:

The correct answers are:

0.95g

g - 0.05g

(1 - 0.05)g

Step-by-step explanation:

Amount of last week's rain = g inches

this week = 5% decrease on last week's amount

5% of last week's amount = 5/100 × g = 0.05g

∴ This week's amount of rain = 0.05g decrease

∴ Amount of rain this week = (Amount of rain last week) - 0.05g

∴ Amount of rain this week = g - 0.05g

This can be simplified by factorizing the common term "g"

g - 0.05g = g(1 - 0.05) = 0.95g

Can someone please help me Please I'm desperate
Yuri [45]

Answer:

James is 37, Rob is 44, and Kate is 35

Step-by-step explanation:

Set up an equation where x is James' age:

Rob's age can be represented by x + 7, since he is 7 years older than James

Kate's age can be represented by x - 2, since she is 2 years younger than James

Add these together in the equation and set it equal to 116:

(x + 7) + (x - 2) + (x) = 116

Add like terms and solve for x:

(x + 7) + (x - 2) + (x) = 116

3x + 5 = 116

3x = 111

x = 37

So, James is 37.

Find Rob's age by adding 7 to this:

37 + 7

= 44

Find Kate's age by subtracting 2:

37 - 2

= 35

So, James is 37, Rob is 44, and Kate is 35

The midpoint of FG is (6-4) and the coordinates of point Fare (-3, 6) What are the coordinates of point G?​
lora16 [44]

Answer:

(15,-14)

Step-by-step explanation:

Given that,

The midpoint of FG is (6-4) and the corrdinates of F are (-3,6).

Let (x,y) be the coordinates of point G. Using mid point formula,

\dfrac{x+(-3)}{2}=6\ \text{and}\ \dfrac{y+6}{2}=-4\\\\x-3=12\ \text{and}\ y+6=-8\\\\x=15,\ \text{and}\ y=-14

So, the coordinates of G are (15,-14).
