express the following equation in the form y=mx+c and identify the gradient:
2y=7x-5
5x-3y=4
10-2x+3y=0
Answer:
y = 7/2x - 5/2 ; gradient is 7/2
y = 5/3x - 4/3 ; gradient is 5/3
y = -2/3x - 10/3; gradient is -2/3
Step-by-step explanation:
2y = 7x-5
2y/2 = (7x - 5)/2 y = 7/2x - 5/25x - 3y=4
(5x-3y) -5x = 4 -5x -3y = -5x + 4-3y/-3 = (-5x+4)/-3 y= 5/3x - 4/310 - 2x+3y = 0
(10-2x+3y) -10 = 0 - 10-2x + 3y = -10(-2x + 3y) + 2x = -10 + 2x 3y = 2x -10 3y/3 = (2x - 10)/3 y = 2/3x -10/3NOTE: The gradient is the slope

Find the center and radius of 2x^2 + 2y^2 - 12x + 8y - 24 = 0
When the equation of the circle is [tex]2x^{2} +2y^{2}-12x+8y-24=0[/tex], then the center of the circle is (3,-2) and the radius of the circle is 6.08 units.
The equation of the circle = [tex]2x^{2} +2y^{2}-12x+8y-24=0[/tex]
The general equation of the circle is [tex]x^{2} +y^{2}+2gx+2fy+c=0[/tex]
Where (-g,-f) is the coordinates of the circle
The equation of the circle = [tex]2x^{2} +2y^{2}-12x+8y-24=0[/tex]
Divide the equation by 2
[tex]x^{2} +y^{2}-6x+4y-12=0[/tex]
Compare the equation with general form
2g= -6
g= -3
2f= 4
f= 2
The center of the circle (-g,-f) = (3,-2)
The radius of the circle = [tex]\sqrt{g^{2}+f^{2}-c }[/tex]
Substitute the values in the equation
r= [tex]\sqrt{(-3)^{2}+2^{2}- (-24) }[/tex]
[tex]=\sqrt{9+4+24} \\=\sqrt{37}[/tex]
=6.08 units
Hence, when the equation of the circle is [tex]2x^{2} +2y^{2}-12x+8y-24=0[/tex], then the center of the circle is (3,-2) and the radius of the circle is 6.08 units.

Enter your answer in the box.
The value of the expression given as −26.6/−1 is 26.6
How to evaluate the expression?The expression is given as
−26.6
-----------
−1
Rewrite the above expression properly as follows
So, we have
−26.6/−1 or −26.6 ÷ −1
This is so because the expression is a quotient expression
So, we have
−26.6/−1
Express −26.6 as -13.3 - 13.3
So, we have the following equation
−26.6/−1 = (−13.3 −13.3)/−1

Describe the graph of the Celsius-Fahrenheit relationship
Using linear function concepts, the graph of the Celsius-Fahrenheit relationship is linear with an intercept of 32 and slope of 1.8.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.From the table, we have that:
When the input is of 0, the output is of 32, hence the intercept is of 32.When the input changes by 10, the output changes by 18, hence the slope is of 18/10 = 1.8.Thus, the graph of the Celsius-Fahrenheit relationship is linear with an intercept of 32 and slope of 1.8.

A rectangular park is 15 miles long and 5 miles wide. How long is a pedestrian route that runs diagonally across the park?
The pedestrian route that runs diagonally across the park is 5√10 miles.
What is the Pythagorean theorem?It states that in a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides.
We have,
A rectangle:
Length = 15 miles
Wide = 5 miles
Diagonal length can be considered as the hypotenuse.
Applying the Pythagorean theorem.
Diagonal side² = length² + wide²
Diagonal side² = 15² + 5²
Diagonal side² = 225 + 25 = 250
Diagonal side = √250 = 5√10 miles.
Thus the pedestrian route that runs diagonally across the park is 5√10 miles.

Answer: EF = 29 units and KM = 22 units
Step-by-step explanation: For the first one, we just add EF and FG, x+14 and 14, and make it equal to EG, 2x+13. We then get x+28 = 2x+13, x = 15. EF = x + 14 and then sub in 15 for x to get 29.
For KM, same deal as the first one. KL and LM, 6 and 2x, equals to KM, 3x-2. 2x+6 = 3x - 2. x = 8. KM = 3x - 2. sub in 8 for x and then we get 22.
when $n$ is divided by 10, the remainder is $a$. when $n$ is divided by 13, the remainder is $b$. what is $n$ modulo 130, in terms of $a$ and $b$? (your answer should be in the form $ra sb$, where $r$ and $s$ are replaced by nonnegative integers less than 130.)
[tex]\bold{n\equiv 91a+40b\ mod \ 130}[/tex]
Given that a is the remainder when n is divided by 10. Then, [tex]n\equiv a\ mod 10[/tex]
Also b is the remainder when n is divided by 13 i.e., [tex]n\equiv b\ mod 13[/tex]
Then by Division algorithm, there are integers k and m such that n = a + 10k and n = b + 13m
These two equations are equivalent to
13n = 13a +130k and 10n = 10b + 130m
Adding these two equations, 23n = 13a + 10b + 130(k + m)
⇒ [tex]23n\equiv 13a+10b\ mod\ 130[/tex]
gcd (23,130) = 1
So 23 has an inverse modulo 130.
Therefore, [tex]n\equiv 23^{-1} (13a+10b) \ mod\ 130[/tex]
Applying Euclidean algorithm for 130 and 23,
130 = 23 x 5 + 15
23 = 1 x 15 +8
15 = 1 x 8 +7
8 = 1 x 7 + 1
Therefore, 1 = 8 - 7 = 8 - (15 -8 ) = 2 x 8 - 15 = 2( 23 - 15 ) - 15
= 2 x 23 -3 x 15 = 2(23) -3(130-5x23) =17(23) -3(130)
So inverse of 23 = 17
So, [tex]n\equiv 17 (13a+10b) \ mod\ 130\equiv 221a +170b \ mod \ 130 \equiv \bold{91a+40b \ mod\ 130}[/tex]

Remote Interior and Exterior Angles in Triangles
Answer:
∠ 2 = 60°
Step-by-step explanation:
the exterior angle of a triangle is equal to the sum of the 2 remote interior angles.
123° is an exterior angle of the triangle , then
∠ 2 + 63° = 123° ( subtract 63° from both sides )
∠ 2 = 60°
Answer:
60
Step-by-step explanation:
The sum of interior angles in a triangle is equal to 180° so we can write the following equation to find the value of missing angle:
∠2 + 63 + 57 = 180 add like terms
∠2 + 120 = 180 subtract 120 from both sides
