What is the equation in point-slope form of a line that passes through the points (5, -3) and (-2, 9) ? A y+3= -2(x- 5)
B y-3 = 12/7(x + 5). C y-3=-2(x+5)
D y+3= 12/7(x-5)
Line through (5, -3) and (-2, 9)
The slope is (9 - -3) / (-2 - 5) = -12/7
Point slope form, point (a,b), slope m, is
y - b = m(x-a)
When we pick the point (a,b)=(5,-3) our answer is
y + 3 = -12/7 (x - 5)
That's almost D except for the sign on the slope. The slope is definitely negative so none of the above is correct.
Answer:
the answer is D

Answer: x is less than or equal to 35.
Step-by-step explanation:
Solve (32-5)+(3*4-2)=
Hello.
Here is the step-by-step
(32-5) + (3*4-2) ---> 27 + (3*4-2)
27 + (3*4-2) ---> 27 + (12-2)
27 + (12-2) ---> 27 + 10
27 + 10 ---> 37
You have to work inside the parenthesis, left to right, then solve.
The result of (32 - 5) + (3 * 4 - 2) is 37.
Begin by solving the operations inside each set of parentheses separately.
For the first parentheses:
32 - 5 = 27
For the second parentheses, calculate the multiplication first before the subtraction:
3 * 4 = 12
Then subtract 2:
12 - 2 = 10
Combine the results: Add the results of the two parentheses together:
27 + 10
Perform the addition:
27 + 10 = 37
what is the the reciprocal of 4/11
Answer: 11/4
Step-by-step explanation: When we are trying to find the reciprocal of a fraction, we just flip the fraction so that our numerator is on the bottom and our denominator is on the top.
In this case, we can change 4/11 to 11/4 by flipping the fraction.
Therefore, the reciprocal of 4/11 is 11/4.

A rectangular field has an area of 162 m2.
The width of the field is 6 m.
What is the length of the field?
Answer:Length: 27m
Step-by-step explanation:
the formula of area of rectangle is : width*lengthso we just replace the values in the formula162=6*LengthLength=162/6Length=27mThe length of the rectangular field is 27 m.
Area of rectangleThe area of a rectangle is the product of length and width.
[tex]\rm{ Area\ of\ rectangle = Length \times width[/tex]
Given to usA rectangular field has an area of 162 m²The width of the field is 6 m.Length of the rectangular fieldAs given to us the shape of the field is rectangular, also, the width of the field is 6 m. therefore,
[tex]\rm{Area\ of\ rectangular\ field= Length \times width[/tex]
[tex]162\ m^2 = Length \times 6\ m\\\\\dfrac{162\ m^2}{6\ m} =Length\\\\ Length=\dfrac{162\ m^2}{6\ m}\\\\Length = 27\ m[/tex]
Hence, the length of the rectangular field is 27 m.

The diagram shows triangle ABC, with AB = xcm, AC = (x+2)cm, BC = 2square root7cm and angle CAB = 60°.
(i) Find the value of x.
To determine x in triangle ABC with given side lengths and an angle, apply the Law of Cosines and solve the resultant quadratic equation.
Explanation:The question asks for the value of x in a triangle with sides AB = x cm, AC = (x+2) cm, and BC = 2√7 cm, with an angle CAB of 60°. This problem can be solved using the Law of Cosines which states that in any triangle, c² = a² + b² - 2ab×cos(C), where c is the side opposite angle C and a and b are the other two sides.
To find the value of x, we substitute the given values into the Law of Cosines formula:
[tex]BC² = AB² + AC² - 2×AB×AC×cos(CAB)(2√7)² = x² + (x+2)² - 2×x×(x+2)×cos(60°)[/tex]Solve for x paying attention to the fact that cos(60°) is 0.5. After simplifying the equation, we obtain a quadratic equation in x, which can be solved using standard algebraic methods.
Note: The provided solution excerpts are related to vector components and do not directly apply to solving this triangle problem.
Darren bought some paint. He used 2 1/4 gallons painting his living room. After that, he had 3 5/6 gallons left. How much paint did he buy?
Answer:
Step-by-step explanation:
Let's pretend this was just whole numbers. So used 2 gallons and had 3 left. Hopefully it's clear you'd have started with 5. It's basically an algebra equation. If we say x is the starting amount then
x-2 = 3
x = 5. Let me know if that doesn't make sense. Now though we can plug in the actual values.
x - 2 1/4 = 3 5/6
x = 2 1/4 + 3 5/6
x = 5 1/4 + 5/6
Now, to add fractions you need to change the denominator. You need to know you can change fractions by multiplying the numerator and denominator by a number. so 1/2 can be 2/4 because 1*2 = 2 and 2*2 = 4. So on you can make it 3/6, 4/8 and on and on and on. This is what we want to use.
We have 1/4 and 5/6. Well, you could try increasing both one by one until you get the same denominator, but a way to do it in one step is to multiply one by the other's denominator. so 1/4 = (1*6)/(4*6) = 6/24 and similarly 5/6 = (5*4)/(6*4) = 20/24. So now we are adding 6/24 + 20/24 = 26/24 or 1 2/24 = 1 1/12. ANyway, now you are adding
5 1/4 + 5/6 = 5 + 1 1/12 = 6 1/12. There is a different way to add fractions, but it's a little more involved and this way always works so that's what I use.
Answer: [tex]6\frac{1}{12}\ gallons[/tex]
Step-by-step explanation:
We can make the conversion from mixed numbers to improper fractions:
Multiply the whole number part by the denominator of the fraction.Add the numerator of the fraction and the product obtained (This sum will be the new numerator).The denominator is the same.Then:
[tex]2\frac{1}{4}=\frac{(2*4)+1}{4}=\frac{9}{4}\\\\3\frac{5}{6}=\frac{(6*3)+5}{6}=\frac{23}{6}[/tex]
We need to add the fractions in order to calculate the amount of paint Darren bought. Since the denominators are differente, we must find the Least Common Denominator (LCD):
[tex]4=2*2=2^2\\\\6=2*3\\\\\\LCD=2^2*3=12[/tex]
Then:
[tex]\frac{9}{4}+\frac{23}{6}=\frac{27+46}{12}=\frac{73}{12}\ gallons[/tex]
To convert this improper fraction to a mixed number:
When you divide 73 by 12 you get a quotient of 6. This will be the whole number.The remainder obtained is 1. This will be the numerator of the fraction. The denominator does not change.Then:
[tex]\frac{73}{12}\ gallons=6\frac{1}{12}\ gallons[/tex]

Savannah went to the grocery store and purchased cans of soup and frozen dinners. Each can of soup has 200 mg of sodium and each frozen dinner has 350 mg of sodium. Savannah purchased a total of 13 cans of soup and frozen dinners which collectively contain 3050 mg of sodium. Write a system of equations that could be used to determine the number of cans of soup purchased and the number of frozen dinners purchased. Define the variables that you use to write the system.
Answer:
65
Step-by-step explanation:
The system of equations is: [tex]\( x + y = 13 \)[/tex] and [tex]\( 200x + 350y = 3050 \)[/tex], where \( x \) represents the number of cans of soup purchased and \( y \) represents the number of frozen dinners purchased.
Let's define:
- \( x \) as the number of cans of soup purchased.
- \( y \) as the number of frozen dinners purchased.
The system of equations would be:
1.[tex]\( x + y = 13 \)[/tex] (since Savannah purchased a total of 13 cans of soup and frozen dinners)
2.[tex]\( 200x + 350y = 3050 \)[/tex] (since each can of soup has 200 mg of sodium and each frozen dinner has 350 mg of sodium, and together they contain 3050 mg of sodium).

According to the Constitution, the amount of time the president and vice president serve in office together for one term is
four years
six years.
seven years
ten years
The correct term for which the President and Vice President serve in office together is four years.
According to the 22nd Amendment to the United States Constitution, the President and Vice President are elected to serve a term of four years. This amendment, ratified in 1951, also limits the President to two terms in office, but each term is four years long. Therefore, the total amount of time a President and Vice President can serve together consecutively is eight years, assuming they are re-elected for a second term. The Constitution does not provide for terms of six, seven, or ten years for the President and Vice President.

The perimeter of a rectangle is 212. The length is 16 more than 5 times the width. Find the dimensions.
Answer:
Dimensions are
Length= 91 units
Width=15 units
Step-by-step explanation:
The formula for perimeter is 2(l+w) where l is length and w is width.
Given perimeter is 212 units
Let the width , w=x units
Length is 16 more 5 times the width= 5x+16 units
So length will be = 5x+16
and width will be= x
Perimeter = 2(l+w)
212=2( 5x+16+x)
212=10x+32+2x
212=12x+32
212-32=12x
180=12x
180/12=12x/12
15=x----------------------width
For length= 5x+16
l=(5*15) +16
l=75+16=91 units-------------length
A family is measuring its house in order to figure out how much paint will be
needed to paint the house. Which is the dependent variable in the relationship?
Answer: How much paint
The independent variable is the measuring of the house
In this context, the dependent variable is the amount of paint needed. This is dependent on the size of the house (the independent variable). As the size of the house changes, it affects the amount of paint needed.
Explanation:In this situation, where a family is trying to figure out how much paint is needed to paint their home, the dependent variable would be the amount of paint needed. This is because the amount of paint is dependent on the size of the house (the independent variable). The independent variable is the one that can be changed or manipulated, in this context it is the size of the house. The dependent variable is what is being measured and it depends on the value of the independent variable, in this case it's the amount of paint needed.
So in simple terms, as the size of the house changes (independent variable), it will affect the amount of paint the family will need (dependent variable).
