I got the question.
give the equation of the line that passes through (1,5) and (-2,3)
Answer:
The equation in point slope form is y= 2/3x+13/3
Step-by-step explanation:
In order to find the equation you need to find the slope, to find the slope you need to graph the two points and use the rise over run method, after using this you can conclude that the slope (m) is 2/3.
To find the y intercept you should plug in one of the points into the point slope formula which is y=mx+b.
Using the first point I get the equation 5=2/3(1)+b, next you isolate the b to get the equation, -b=2/3-5
Then write all the numerators above the common denominator getting 2-15/3
With this you get -b=-13/3 and then you can divide both sides by -1 to get a positive b.
Plug all of these into y=mx+b getting y=2/3x+13/3

Which value is the solution to the equation? -3(t-7) = 24
Answer:
-3(t - 7) = 24
t - 7 = -8
t = -1
Final answer:
The correct solution to the equation -3(t-7) = 24 is t = -1, which contradicts the reference indicating solutions for a different quadratic equation.
Explanation:
The equation presented, -3(t-7) = 24, does not yield the solutions t = 3.96 and t = -1.03 as the provided reference indicates. Instead, those solutions seem to be related to a different quadratic equation. To solve the given linear equation for t, you need to perform the following steps:
Distribute the -3 across the parenthesis: -3t + 21 = 24.Subtract 21 from both sides of the equation: -3t = 3.Divide both sides of the equation by -3: t = -1.Therefore, the solution to the equation -3(t-7) = 24 is t = -1.

A fruit company delivers its fruit in two types of boxes: large and small. A delivery of 2 large boxes and 5 small boxes has a total weight of 57 kilograms. A delivery of 8 large boxes and 3 small boxes has a total weight of 126 kilograms. How much does each type of box weigh?
Final answer:
The large box weighs 13.5 kilograms and the small box weighs 6 kilograms.
Explanation:
To solve this problem, we can assign variables to represent the weight of each type of box. Let's say the weight of a large box is L and the weight of a small box is S.
From the given information, we can set up a system of equations:
2L + 5S = 57 (Equation 1)
8L + 3S = 126 (Equation 2)
We can solve this system of equations using the method of substitution or elimination. Let's use elimination:
Multiply Equation 1 by 8 and Equation 2 by 2 to eliminate the S variable:
16L + 40S = 456 (Equation 3)
16L + 6S = 252 (Equation 4)
Subtract Equation 4 from Equation 3:
34S = 204
Solve for S: S = 6
Substitute the value of S into Equation 1:
2L + 5(6) = 57
2L + 30 = 57
2L = 27
Solve for L: L = 13.5
Therefore, the large box weighs 13.5 kilograms and the small box weighs 6 kilograms.

A woodland jumping mouse hops along the ground along a parabolic path that can be modeled by the following equation: y = −0.2x2+1.3x (where x is the horizontal position in feet and y is the height in feet). What is the maximum height the mouse can jump?
Answer:
2.1125 feet
Step-by-step explanation:
the vertex will be the maximum value of this parabola.
the general form for a quadratic equation is: ax² + bx + c, for this equation,
a = -0.2, b = 1.3, and c = 0
find the vertex by first using the formula x = -b/(2a)
x = -1.3/(2*-0.2)
x = -1.3/-0.4
x = 3.25
Now plug in that x value to find the actual maximum height
y = -0.2(3.25)² + 1.3(3.25)
y = -0.2(10.5625) + 4.225
y = -2.1125 + 4.225
y = 2.1125 feet
The maximum height the mouse can jump is approximately 2.1125 feet.
To find the maximum height the mouse can jump, you need to determine the vertex of the parabolic path because the vertex represents the highest point on the path. The equation of the path is given as:
y = -0.2x^2 + 1.3x
To find the vertex, you can use the formula:
x_vertex = -b / (2a)
Where "a" is the coefficient of the x^2 term, and "b" is the coefficient of the x term in the equation.
In your equation, a = -0.2 and b = 1.3. Plug these values into the formula:
x_vertex = -1.3 / (2 * (-0.2))
x_vertex = -1.3 / (-0.4)
x_vertex = 3.25
Now that you have the x-coordinate of the vertex, you can find the corresponding y-coordinate by plugging it back into the equation:
y = -0.2x^2 + 1.3x
y_vertex = -0.2(3.25)^2 + 1.3(3.25)
Calculate:
y_vertex = -0.2(10.5625) + 4.225
y_vertex = -2.1125 + 4.225
y_vertex = 2.1125

250 people were asked to name their favorite fruit.
Berries/ 44%
Peaches 32%
Cherries 24%
A: Of those surveyed, how many people prefer peaches?
B: Which type of fruit did more than 100 people prefer
Answer:
Step-by-step explanation:
A. 250 x .32 = 80
B. 250 x .44 = 110 So, the answer is berries.
Final answer:
Out of 250 surveyed individuals, 80 people prefer peaches. Berries are the preferred choice of more than 100 people.
Explanation:
A total of 250 people were surveyed about their favorite fruit. To find out how many people prefer peaches, we calculate 32% of 250 people. This calculation is done by multiplying the total number of people by the percentage of those who prefer peaches:
250 people x 32% = 250 x 0.32 = 80 people
Therefore, 80 people prefer peaches.
To determine which type of fruit more than 100 people prefer, we apply the same calculation method. Here are the calculations:
Berries: 250 x 44% = 110 people
Peaches: 250 x 32% = 80 people
Cherries: 250 x 24% = 60 people
More than 100 people prefer berries.

Which description can represent the surface area of this trunk
Answer:
It's B.
Step-by-step explanation:
A trunk has six faces . The total surface area will be the sum of the areas of these faces.
The surface area of a rectangular prism (like a trunk) is the total area of the surface of the object and can be found using the formula A = 2lw + 2lh + 2wh, where 'l' represents length, 'w' represents width and 'h' represents height.
Explanation:The surface area of a trunk, or any three-dimensional object, refers to the total area that the surface of the object occupies. In the case of a trunk, if we consider it as a rectangular prism (a box shape), that surface area can be found by adding the areas of all six faces of the prism. The formula to calculate the surface area (A) of a rectangular prism is A = 2lw + 2lh + 2wh where l denotes length, w width, and h height. Let's say, for example, that your trunk has a length of 3 units, a width of 4 units, and a height of 2 units. The surface area would then be 2*(3*4) + 2*(3*2) + 2*(4*2) = 24 + 12 + 16 = 52 square units.

A) x > 3 4
B) x < 3 4
C) x > - 4 3
D) x < - 3 4
Answer:
A: x > 3/4
Step-by-step explanation:
First you simplify the equation.
Simplify 1/3x
Then Simplify the left side.
1/2-x/3<x/3
Move x/3 to the left side of the equation by subtracting it from both sides.
1/2-x/3-x/3<0
Now simplify the left side.
1/2-2x/3<0
Find the LCD of the terms of the equation. In this case it's 6.
Multiply each term by 6 and simply.
3-2x<2x
Move all terms that contain a x to the left side of the inequality.
3-4x<0
Subtract 3 from both sides.
-4x<-3
Now divide each term by -4 and simplify.
This gives us our answer of x > 3/4.

Rounded to the nearest whole number, how many 2ft by 2 ft squares will fit into circle that has a diameter of 20 feet
Answer:
79
Step-by-step explanation:
A square that has side length [tex]l=2 ft[/tex] has area [tex]2^2=4ft^2[/tex].
A circle that has a diameter 20 feet has area [tex]A=\frac{\pi d^2}{4}[/tex]
We substitute the diameter into the formula to obtain;
[tex]A=\frac{\pi \times 20^2}{4}=100\pi ft^2[/tex]
The number of squares that has area 4 feet square that can fit into a circle with area [tex]100\pi ft^2[/tex] is
[tex]=\frac{100\pi}{4}=25\pi=78.5398[/tex]
When we round to the nearest whole number; we have 79 squares.
Approximately 79 squares of size 2 ft by 2 ft can fit into a circle with a diameter of 20 feet.
To accurately determine how many 2ft by 2ft squares can fit into a circle with a diameter of 20 feet, let's perform a step-by-step calculation:
1. Calculate the area of the circle:
[tex]\[ \text{Area of the circle} = \pi r^2 \][/tex]
Given the diameter is 20 feet, the radius r is 10 feet:
[tex]\[ \text{Area of the circle} = \pi \times 10^2 = 100\pi \approx 314.16 \text{ square feet} \][/tex]
2. Calculate the area of one 2ft by 2ft square:
[tex]\[ \text{Area of one square} = 2 \times 2 = 4 \text{ square feet} \][/tex]
3. Calculate the theoretical maximum number of squares that can fit into the circle by dividing the area of the circle by the area of one square:
[tex]\[ \text{Theoretical number of squares} = \frac{\text{Area of the circle}}{\text{Area of one square}} = \frac{314.16}{4} \approx 78.54 \][/tex]
4. Round to the nearest whole number:
