Answer: 3 equations
Step-by-step explanation:
The 4th one doesn’t work for both pairs.
1st : 3 - 7 = -4 | 5 x 2 = 10 5 x 4 = 20
10 - 20 = -10.
-4 does not equal -10
2nd equation : -7 - 7 = -14
5 x 4 = 20| 5 x 4 = 20 20 - 20 = 0
-14 does not equal 0
The only one equation that represents the line passing through both points is y = -x + 5. which is the correct answer that would be an option (D).
What is an equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
To determine the number of the given equations representing the line passing through the points (2,3) and (4,-7), you can substitute the coordinates of these points into the equations and see if they are satisfied.
If an equation is satisfied by both points, then the line described by that equation passes through both points.
Here are the given equations:
A. y = 3x + 5
B. y = -7x + 1
C. y = x + 1
D. y = -x + 5
E. y = -1/3x + 1
Substituting the coordinates of the point (2,3) into each of these equations, we find that equations A, C, and D are satisfied by this point.
Substituting the coordinates of the point (4,-7) into each of these equations, we find that equations B and D are satisfied by this point.
Therefore, the only one equation that represents the line passing through both points is D. Thus, the answer is 1.

Abag of peanuts is 5 times as heavy as a bag of sunflower seeds. The bag of peanuts
also weights 920 grams more than the bag of sunflower seeds. What is the total weight
in grams for the bag of peanuts and the bag of sunflower seeds?
Answer:
5s=p
s+920=p
5s=s+920
*subtract s from both sides*
4s=920
*divide 4 from both sides*
s=230
230*5=1150
The bag of sunflower seeds weighs 230 grams and the bag of peanuts weighs 1150 grams.
9514 1404 393
Answer:
1380 grams
Step-by-step explanation:
The ratio of weights is ...
peanuts : sunflower seeds = 5 : 1
Then the difference in weights is ...
5 - 1 = 4 . . . . ratio units
The sum of weights is ...
5 + 1 = 6 . . . . ratio units
That is the sum of the weights related to the difference of weights is ...
sum : difference = 6 : 4 = 3 : 2
So, the total weight of the two bags is 3/2 times the difference in their weights:
total weight = (3/2)(920 grams) = 1380 grams
You are building a model of a mall. The scale factor is 6:24. The model is 9 inches tall. How tall is the actual statue?
Answer: 36 inches
Step-by-step explanation:
height of the building = 9inches.
scale factor of the building = 6:24.
solution
since a scale of 6:24, was used to scale down the original model, the initial or actual height of the statue would be.
[tex]= 9 * \frac{24}{6} \\\\= 9 * 4\\\\= 36 inches[/tex]

Find the lengths of the diagonals of rectangle QRST, if QS=14x+10 and RT=11x+22.
Answer:4
Step-by-step explanation:
diagonals of a rectangle are equal therefore QS=RT, 14x+10=11x+22, and solve for x to get 3x=12, so x equals 4
List the sides in order from the smallest to the largest
Answer:
The answer would be A, or line LJ, line KL, and line JK.
Step-by-step explanation:
You can tell which lines are smaller by using the angle measurements. The direction from which the angle is shown points to their respected line.
So, angle K goes with line LJ
Angle J goes with line LK
And angle L goes with line JK.
The size of the angle determines the size (not actual size) of the line.

Write two expressions with unlike denominators whose sum is x-3/x+2, I need help it is confusing for me.
Answer:
[tex]\displaystyle A=\frac{x-2}{x+3}[/tex]
[tex]\displaystyle B=\frac{-5}{(x+3)(x+2)}[/tex]
Step-by-step explanation:
We need to find two expressions with unlike denominators what sum
[tex]\displaystyle S=\frac{x-3}{x+2}[/tex]
Let's suppose one of the expressions is:
[tex]\displaystyle A=\frac{x-2}{x+3}[/tex]
Now we subtract S minus A to find the other expression B:
[tex]\displaystyle B=S-A=\frac{x-3}{x+2}-\frac{x-2}{x+3}[/tex]
Multiply the first fraction by x+3 and the second by x+2;
[tex]\displaystyle B=(x+3)\frac{x-3}{(x+3)(x+2)}-(x+2)\frac{x-2}{(x+3)(x+2)}[/tex]
Operating:
[tex]\displaystyle B=\frac{x^2-9}{(x+3)(x+2)}-\frac{x^2-4}{(x+3)(x+2)}[/tex]
Subtracting both fractions with like denominators:
[tex]\displaystyle B=\frac{x^2-9-(x^2-4)}{(x+3)(x+2)}[/tex]
Simplifying:
[tex]\displaystyle B=\frac{-5}{(x+3)(x+2)}[/tex]
Thus the two expressions are:
[tex]\displaystyle A=\frac{x-2}{x+3}[/tex]
And
[tex]\displaystyle B=\frac{-5}{(x+3)(x+2)}[/tex]

A triangle is inscribed in a rectangle if each vertex of the triangle lies on a side of or at a vertex of the rectangle. This diagram shows shaded triangle ACE inscribed in rectangle ABDE. Find the number of square units in the area of shaded triangle ACE, if the area of the rectangle is 13.5 square units. NEED QUICKLY
Answer:
6.75
Step-by-step explanation:
So basicly we know the area of the rectangle which really helpful.
So lets take the formula of the are for the triangle, which is b*h*1/2
So we know that the height and bass of the triangle is the same as the rectangle's legnth and width.
Meaning that we can replace b*h with 13.5.
So plug that into the quation.
13.5*1/h= Area of ACE
6.75= Area of ACE
hence, 6.75 is your answer
The area of the triangle ACE is; 6.75 square units.
According to the question; a triangle is inscribed in a rectangle with each vertex of the triangle lieing on a side of or at a vertex of the rectangle.
From the statement above, it is evident that the triangle in question covers half the area occupied by the rectangle.In essence, to find the number of square units in the area of shaded triangle ACE,
We have to divide the area of the rectangle by 2.
Therefore, the area of the triangle ACE is;
6.75 square units.

Martin bought a new carpet to cover a room. The carpet is in the shape of a square and it covers an area of 200 ft2. How long is the side length of the carpet?
Answer:
14.14 ft long
Step-by-step explanation:
Martin bought a new carpet to cover a room. The carpet is in the shape of a square and it covers an area of 200 ft². How long is the side length of the carpet?
The Area the carpet covers is a square.
Hence, the Area of a square = (Side length)²
From the question, we are given the Area of the square = 200 ft²
Hence:
200 ft² = (Side length)²
We square root both sides.
√200 ft² = √(Side length)²
Side length = 14.142135624 ft
Approximately = 14.14 ft
The side length of the carpet is 14.14 ft long
Is 14/950 more or less than 1/2 and why!
A store is having a Back To School Sale.The total for a skirt,a pair of shoes,and a pair of socks is $32.35 before tax.The pair of socks costs $3.75.The original prices of the skirt and shoes were the same.What was the sales price of the skirt
Answer:
The sales price of the skirt was $14.3.
Step-by-step explanation:
From the information given, you know that the total for the three items is $32.35 which is:
x+y+z=32.35
x is a skirt
y is a pair of shoes
z is a pair of socks
Also, you know that the pair of socks costs $3.75, so you can replace the value of z and subtract this from the total amount to have the price of the skirt plus the pair of shoes:
x+y+3.75=32.35
x+y=32.35-3.75
x+y=28.6
Now, as the original prices of the skirt and shoes were the same and you know that the sum of the two items is equal to $28.6, you can divide this by 2:
$28.6/2=$14.3
According to this, the answer is that the sales price of the skirt was $14.3.

Answer:
343 cubic feet
Step-by-step explanation:
A company rents a storage unit. The unit is in the shape of a cube.
The formula V=s^3 can be used to find the volume of a cube.
Using the formula, determine the volume of the storage unit if the side length (s) is 7 feet.
From the above question
Side length (s) = 7 feet
Formula for the cube = V = s³
Volume of the cube(storage unit) = (7 feet)³
= 343 cubic feet
