x + y = -3
y = 2x
Answer:
x = -1
y = -2
Step-by-step explanation:
You can use the method of substitution to solve this equation. Since you know that y= 2x, you can substitute that value into x + y = -3:
x + (2x) = -3
Combine like terms:
3x = -3
x = -3/3
x = -1
Now that you know the value of x, you can substitute it into any of the two equations (I'll be choosing y = 2x)
y = 2x
y = 2 (-1)
y = -2
So your solution is x = -1, y = -2
Point form: (-1, -2)

Given w = −168i −160j, what are the magnitude and direction of −4w? Round the answers to the nearest whole number.
232; 224°
232; 44°
928; 224°
928; 44°
Answer:
Magnitude and Direction is 928 and 44
Step-by-step explanation:
For a Vector w = (x)i+(y)j
The Magnitude of w [tex]=\sqrt{x^{2} +y^{2} }[/tex]
and the Direction of w [tex]=tan^{-1}(\frac{y}{x} )[/tex]
So for our Question , w = - 168i - 160j
Then -4w = -4 (- 168i - 160j) = (-4*-168)i +(-4*-160)j = 672i + 640j
Then the Magnitude of -4w = [tex]\sqrt{672^{2} +640^{2} } =928[/tex]
and the Direction of -4w = [tex]tan^{-1}(\frac{640}{672} )=tan^{-1}(\frac{20}{21} )=44[/tex] ( to the nearest whole number)

Ms. wilkinson's fifth-grade class is running a canned food drive. the students filled two boxes of food. there are thirty 300-gram cans of soup in one box. there are eighteen 400-gram cans of vegetables in the other box. how many kilograms of food did the students collect in all?
Answer:
16.2 kilograms
Step-by-step explanation:
30 300-gram cans = 9000 grams of soup
18 400-gram cans = 7200 grams of vegetables
9000 + 7200 = 16200 grams
1000 grams = 1 kilogram
16200 / 1000 = 16.2 kilograms
The total amount of food students collect in kilograms will be equal to 16.2 kilograms food.
What is algebra ?
Algebra is a branch of mathematics that deals with various symbols and the arithmetic operations such as division , multiplication , etc.
The number of cans of soup in one box = 30 cans
And each can has 300 grams of soup.
So , the total amount of soup in one box is :
= 30 × 300
= 9000 grams of soup
Now , in the other box there are 18 cans of vegetables and each can has 400 grams of vegetable.
So , the total amount of vegetable in the other box is :
= 18 × 400
= 7200 grams
Total food students collect is :
= 9000 grams soup + 7200 grams vegetables
= 16200 grams food
We know that :
1000 grams = 1 kilogram
So , converting grams into kilograms we get :
16200 / 1000 = 16.2 kilograms food
Therefore , the total amount of food students collect in kilograms will be equal to 16.2 kilograms food.

2.) h(-3) = -1
Since the range is from 1 to 25. Therefore, this is not the correct option.

? Question
Segment FG is on a number line with point F at 1.2. Point H lies on FGat 3.15. Point H is the length of FGfrom point G. What
are the location of G and the length of FG?
Type the correct answer in each box. Use numerals instead of words.
The location of G is?
The length of FG is?
A number line is a line that shows the locations of all directed numbers. The answers required to the question are:
i. The location of G is 2.18.
ii. The length of FG is 0.98.
A number system is a system that can be used to locate the position of directed numbers on a number line. A number line has two ends: positive and negative ends. This starts from negative infinity to positive infinity. Thus all numbers can be located on a number line.
Directed numbers are numbers that have either a positive sign or a negative sign. Thus all numbers are directed numbers.
From the given question, let the distance between FG and GH be represented by x (since Point H is the length of FG from point G).
Thus,
Point FH = 3.15 - 1.20
= 1.95
x = [tex]\frac{FH}{2}[/tex]
= [tex]\frac{1.95}{2}[/tex]
x = 0.975
So that,
Location of point G = 1.200 + 0.975
= 2.175
Therefore, the location of G is 2.175 (2.18). And the length of FG is 0.975 (0.98).

Answer:
The second graph
Step-by-step explanation:
Well you're given the equation in slope-intercept form, which looks like: y=mx+b, where m is the slope, and b is the y-intercept. This is because the y-intercept is when x=0, so mx will becomes 0, thus leaving b alone, and making it the y-intercept. m is the slope because as x increases by 1, the y-value goes up by m, so the "rise" is m and the "run" is 1. The definition of the slope is rise/run so the slope would be m/1 or just m.
So let's analyze the equation: y=25x+40. the slope will be 25, and the y-intercept will be 40 (this is important for easily filtering very obviously wrong answer). So the linear equation will intersect the y-axis at (0, 40). Only one of the graphs intersects the y-axis at (0, 40) which is the second graph.

The difference in the height of the two rectangles is 7 feet.
One rectangle has a height of 6.2 feet and another has a height of y feet.
What is the value of y?
Answer:
y = 13.2ft
Step-by-step explanation:
This is a bit of trial and error.
We know that the height of one rectangle is 6.2ft, which means we cannot subtract 7 from 6.2 to find the height of the other rectangle as it will give us a negative value and it will not make sense.
Therefore the height of the other rectangle has to be 7ft higher.
