Question 2 :
[tex]\boxed{-35}[/tex]
Question 3:
[tex]\boxed{7}[/tex]
Question 4:
[tex]\boxed{-5}[/tex]
Question 5:
[tex]\boxed{-5}[/tex]
Step-by-step explanation:
The easiest points to take on the line are those where x =0, y = 35 (0,35) and x = 7, y =0 (7,0)
Question 2.
We can see that between these two points, the y value decreases linearly from 35 to 0. So the rise between (0, 35) and (7,0) = [tex]0 -35 = -35[/tex]
Question 3
[tex]\textrm{Between (0, 35) and (7,0) the x value increases from 0 to 7 so the run is 7}[/tex]
Question 4
[tex]\dfrac{rise}{run}= \dfrac{-35}{7}= -5}[/tex]
Question 5
Slope is the same as rise over run
We can also write this as
[tex]\dfrac{0-35}{7-0} = \dfrac{-35}{7} = -5[/tex]
Though not asked for, the equation of the line is
[tex]y = -5x + 35[/tex]

-6x+3y-15z=9
Answers
Therefore , the solution of the given problem of equation comes out to be x = 73/19 , y = 5/19 and z = 18/19.
Equation: What is it?In a mathematical formula, the equal symbol (=) is used to denote that the statements are equivalent. It is demonstrated that many numerical variables are comparable using mathematical equations, which are statements of reality. The equal sign, for instance, separates the numbers 12 or b + 6 split separate halves of the equation y + 6 = 12. It is possible to calculate how many words each sides of a symbol represents. The meaning of a symbol usually contradicts itself.
Here,
Given :
=> x-3y+z=4....... (1)
=>2x-8y+8z=-2 ........ (2)
=> -6x+3y-15z=9 ......... (3)
Multiply eq (1) by 2 and subtract from eq (2)
=> 2x - 6y + 2z -2x +8y +8z = 8 +2
=> 2y +10z =10
=> y + 5z =5 ..... (4)
and
Multiply eq (2) by 3 and add to eq (3)
=> 6x - 24y +24z -6x + 3y -15z =-6 +9
=> -21y + 9z = 3
=> -7y + 3z =1 ..... (5)
So ,
from eq (4) and (5)
=> y = 5 -5z
=> -7(5-5z) + 3z = 1
=> -35 + 35z + 3z =1
=> 38z = 36
=> z = 36/38
=> z = 18/19
and
=> y = 5 - 5 (18/19)
=> y = 95 -90/19
=> y = 5/19
and
=> x = 4 -z +3y
=> x = 4 - 18/19 +15/19
=> x = 76 -3 /19
=> x = 73/19
Therefore , the solution of the given problem of equation comes out to be x = 73/19 , y = 5/19 and z = 18/19.

A tring i placed on the outide of a clock going clockwie from 12to 9. The clock ha a radiu of 6 inche. What i the length of the tring
Answers
The length of the string is 37.7 inches string is placed on the outside of a clock going clockwise from 12 to 9.
To calculate the length of the string, first, start with the fact that the circumference of a circle is equal to pi multiplied by the diameter. The diameter of the clock is 12 inches, so then the circumference is 12π or 37.7 inches.
Since the string is going around the outside of the circle, the length of the string is equal to the circumference which is 37.7 inches. To get this answer, take the radius (6 inches) of the clock and double it to get the diameter (12 inches).
Multiply the diameter by pi (3.14) to get the circumference (37.7 inches) and then the length of the string is the same as the circumference.

Answers
The correct option is (iii) Isosceles triangle is the one which has only 2 equal sides.
Every triangle is made up of three sides and three angles. A side is opposing an angle or a vertex if none of its ends is at the given angle's vertex. An angle is included between two sides if their common terminus is the angle's vertex.
Triangles are divided into one of three types based on the lengths of its sides: scalene, isosceles, or equilateral. A triangle is scalene if none of its sides are equal (of equal length). The triangle is isosceles if two or more of its sides are equal. A triangle is equilateral if all three of its sides are equal. By definition, all equilateral triangles are also isosceles.

What is the area in square units of triangle def?
Answers
Triangle DEF is an isosceles triangle, with two sides of length 8 and one side of length 10.

The semiperimeter of triangle DEF is (8+8+10)/2 = 16. Substituting these values into Heron's formula yields A = √(16(16-8)(16-8)(16-10)) = √(256(8)(8)(6)) = √11520 = 107.3.

What is the rule of the sequence 2 4 6?
Answers
The rule of the sequence 2 4 6 is that each term is obtained by adding 2 to the previous term.
In an arithmetic sequence, the rule is that each term is obtained by adding a fixed value (common difference) to the previous term. In this case, the common difference of the sequence 2 4 6 is 2. So, 2 is added to the first term (2) to get the second term (4), and 2 is added to the second term (4) to get the third term (6).
It is also possible to express the rule of the sequence by using the formula of an arithmetic sequence, which is a_n = a_1 + (n-1)d, where a_1 is the first term, d is the common difference, and n is the number of the term.
In this case, a_1 = 2, d = 2, so the rule of the sequence is a_n = 2 + (n-1)2 = 2n, where n is the number of the term.
