Write the equation of the line in slope-intercept that has passes through the points (2,-5) and (8, 13).
Answer:
The equation of the straight line in Slope- intercept form
y = 3 x - 11
Step-by-step explanation:
Explanation:-
Given points are (2,-5) and (8, 13)
The Slope of the line
[tex]m = \frac{y_{2} -y_{1} }{x_{2} -x_{1} } = \frac{13-(-5)}{8-2} = \frac{18}{6} =3[/tex]
Equation of the line having slope 'm' and given point
[tex]y - y_{1} = m (x - x_{1} )[/tex]
(x₁ , y₁) = ( 2, -5 )
[tex]y - (-5) = 3 (x - 2 )[/tex]
y + 5 = 3x - 6
The equation of the straight line in slope intercept form
y = m x + c
y = 3 x - 6-5
y = 3 x - 11
Final answer:-
The equation of the straight line in Slope- intercept form
y = 3 x - 11

Answer:
120; 643 units squared
Step-by-step explanation:
Perimeter: Add all the sides, so 120 units
_________________________________
Area: First multiply 19 by 24 for the first shape within this other shape, so That equals 456 units squared. Since we know that one whole side is 36 we can subtract 19 from it to get the lower side of the smaller shape and then multiply that by 11. So the smaller side ends up being 17. So 17 times 11 equals: 187 units squared. Then just add the areas together 187+456=643 units squared.

Write an equation in slope-intercept form for the line that passes through the given point and is parallel to the following equation. Point: (5,4) Equation: y = 2/5x - 2
Answer:
y = (2/5)x + 2
Step-by-step explanation:
The given equation y = (2/5)x - 2 is already in slope-intercept form. The equation of the new line has precisely that form, except that the constant is different. To find the new constant (which is the y-intercept), replace x with 5 and y with 4 in y = (2/5)x + C:
4 = (2/5)(5) + C, or
4 = 2 + C. Therefore, C = 2 and the equation of the new line is y = (2/5)x + 2.

solve the inequality
please .. if you can show your work i dont understand it
Answer:
X ≥ 3
Step-by-step explanation:
First you simplify, as if the ≤ is an = (just don't multiply with a negative number)
27 = 7X + 6
27 - 6 = 7X
21 = 7X
3 = X
Then you put the ≤ back in
3 ≤ X
and put the X up front. The ≤ then swaps into a ≥
Finally, you can do a test with X = 2 (should be false) and X=4 (should be true), to check wether you made any mistakes.

Answer: x = 29
Step-by-step explanation:
The four angles of a Parallelogram equal to 360. Its name is derived from the fact that its made up of two sets of parallel lines which means that its opposite angles are equivalent. Fortunately, you are given the values for the angles that are not equivalent which means you can create an equation and solve for x.
5x - 23 + 5x - 23 + 2x + 2x = 360
14x - 46 = 360
14x = 406
x = 29

Walter took a total of 16 quizzes over the course of 2 weeks. After attending 4 weeks of school this quarter, how many quizzes will Walter have taken in total?
Answer:
32 quizzes
Step-by-step explanation:
It is given that,
Walter took a total of 16 quizzes over the course of 2 weeks.
16 quizzes = 2 weeks
⇒ 1 weeks = 8 quizzes
We need to find attending 4 weeks of school this quarter, how many quizzes will Walter have taken in total.
⇒ 4 weeks = 4 × 8 quizzes
= 32 quizzes
So, 32 quizzes will Walter have taken in total.
Mrs. Larson, the science teacher, collected 18 sedimentary rocks and 12 metamorphic ones. Now she wants to create some identical kits for studying rocks, without having any rocks left over. What is the greatest number of kits she can create?
Answer:
The greatest number of kits she can create is 6 kits
Step-by-step explanation:
We can solve the above question using the greatest common factor method.
We have to find the factors of 18 and 12
The factors of 12 are: 1, 2, 3, 4, 6, 12
The factors of 18 are: 1, 2, 3, 6, 9, 18
Then the greatest common factor is 6.
Therefore, greatest number of kits that she can create is 6 kits
The number of sedimentary rocks in each kit
18 sedimentary rocks /6 kits = 3 sedimentary rocks
The number of Metamorphic rocks in each kit =
12 metamorphic ones/ 6 kits = 2 metamorphic rocks

Options A, B, and C are the correct answer.
What is a cube?It is a polygon having six faces.
The volume of a cube is side³.
We have,
A regular polygon is a polygon where all the sides are equal and the interior angles are equal.
Now,
Figure 1 is a triangle.
Figure 2 is a parallelogram.
Figure 3 is a square.
Figure 4 does not have the same side and the same interior angles.
Thus,
Figure 4 is not a regular polygon.

If the manufacturer gains 6 %, the wholesale dealer 8% and the retailer 10 %. Then what
is the production cost of geyser whose retail price is Rs. 15741?
Answer:
The production cost is Rs 12,500
Step-by-step explanation:
Let the production cost be $x
At any point in time
sales price = cost price +( profit percentage* cost price)
Manufacturer gaining 6%
That would be;
x + 6% of x
x + 0.06x
= 1.06x
Wholesaler gaining 8%
= 1.06x + 8% of 1.06x
1.06x + 0.08(1.06x)
= 1.06x + 0.0848x
= 1.1448x
The for the retailer
= 1.1448x + 10% of 1.1448x
= 1.1448x + 0.11448x
= 1.25928x
1.25928x = 15,741
x = 15,741/1.25928
x = 12,500

On Tuesday, the ratio of the number of cakes sold to the number of scones sold was
5:2
On Tuesday, the cafe sold 80 scones.
How many cakes were sold on Tuesday?
Answer:
200 cakes
Step-by-step explanation:
1) divide 80 by 2 to get 40
2) times 40 by 5 50 get 200
answer is 200 cakes sold on Tuesday
On Tuesday, the cafe sold 200 cakes which is the ratio of the number of cakes sold to the number of scones sold was 5:2.
What is the proportion?A mathematical assessment of two numbers is called a proportion. If two sets of provided numbers rise or fall in the same relation, then the ratios are said to be directly proportional to each other. Proportions are represented by the symbols "::" or "=".
We have been given that the ratio of the number of cakes sold to the number of scones sold was 5:2, on Tuesday.
On Tuesday, the cafe sold 80 scones.
Let's assume that x number of cakes sold on Tuesday
According to the given condition, the proportion would be
5 cakes : 2 scones = x cakes : 80 scones
⇒ 5/2 = x /80
Apply the cross multiplication,
⇒ 5 × 80 = 2x
⇒ 400 = 2x
⇒ 2x = 400
⇒ x = 400/2
⇒ x = 200
Therefore, on Tuesday, the cafe sold 200 cakes.

The rate of change in y = 24x
Answer:
24
Step-by-step explanation:
Using the formula y = mx + b we can find the slope or rate of change. First we must convert it into the formula or equation we currently have which is y = 24x + 0.
24 = m
x = x
0 = b
m is always the rate of change or slope so by finding m we find the slope or rate of change.
