Equation of straight line is y=mx+c
choose any two points on straight line
for me I choose:(-3,11) and (3,-1)
use these two points to find gradient,m.
m= (-1-11)/(3-(-3))
m= -2
now, y=-2x+c
choose any point on the straight line
I choose point (3,-1)
sub the point into the equation to find c
-1=-2(3)+c
c=5
equation: y=-2x+5

Answer:
Ok so 25$ for an adult. there are x adults so x times 25 is equals to $25x
13 dollars per child and y children so $13y
$20 for each pensioner and p pensioners so $20p
when adding these notice that none of the variable(latters) are the same so n adding will take place leaving the answer
$25x + $13y + $20p
a) $25x
b) $13y
c) $20p
d) $25x + $13y + $20p
Answer:
a) $25x, this is because if there are x number of adults coming, and $25 is the per adult charge, then irrespective of the number of adults coming this will be the equation. Eg : x = 5 So, $25 * 5 = $125
b) $13y, this is because if there are y number of children coming, and $13 is the per child charge, then irrespective of the number of children coming this will be the equation. Eg : y = 4 So, $13 * 4 = $52
c) $20p , this is because if there are x number of pensioners coming, and $20 is the per pensioner charge, then irrespective of the number of pensioner coming this will be the equation. Eg : p = 2 So, $20 * 2 = $40
d) so, the total will be, = $25x + $13y + $20p

what number must 200 be multiplied by to make it a perfect square
Answers
Answer:
2
Step-by-step explanation:
Thus, we must multiply 200 by 2, so that the product becomes a perfect square. 400 is asquare of 20. So, the least number is 2, by which 200 must be multiplied so that the product becomes a perfect square.
Answer:
Step-by-step explanation:
200 = 2 * 2 * 2 * 5 * 5
To make it a perfect square, you need to multiply by 2
200 * 2 = 400 = 20²
2(a-c)=4a solve for a
Answers
Answer:
Here you go :)
So, you can't really answer this, but you can simplify it.
Simplifying
2(a + -1c) = 4a
(a * 2 + -1c * 2) = 4a
(2a + -2c) = 4a
Solving
2a + -2c = 4a
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-4a' to each side of the equation.
2a + -4a + -2c = 4a + -4a
Combine like terms: 2a + -4a = -2a
-2a + -2c = 4a + -4a
Combine like terms: 4a + -4a = 0
-2a + -2c = 0
Add '2c' to each side of the equation.
-2a + -2c + 2c = 0 + 2c
Combine like terms: -2c + 2c = 0
-2a + 0 = 0 + 2c
-2a = 0 + 2c
Remove the zero:
-2a = 2c
Divide each side by '-2'.
a = -1c
Simplifying
a = -1c

If f = {(0,2), (2,6), (3,15),(4,9)} and g = {(3,4), (2,1),(4,6), (5,9)},
what is (f x g)(3)?
Answers
Considering the given relations, the value of the multiplication of f(x) and g(x) at x = 3 is given by:
(f x g)(3) = 60.
What is the multiplication of f(x) and g(x) at x = 3?The multiplication is given by the multiplication of each of the numeric values at x = 3, hence:
(f x g)(3) = f(3) x g(3).
The values are found as follows:
The first relation has point (3,15), hence f(3) = 15.The second relation has point (3,4), hence g(3) = 4.Hence the multiplication is given by:
(f x g)(3) = f(3) x g(3) = 15 x 4 = 60.

What are some similarities and differences between the Third Angle Theorem and the Triangle Angle-Sum Theorem?
Answers
Answer:
The similarities are;
1) The Third Angle Theorem and the Triangle Angle-Sum Theorem are based on the sum of the angles in a triangle being equal to 180°
2) The Third Angle Theorem and the Triangle Angle-Sum Theorem are used to prove the measure of the third
3) The Third Angle Theorem and the Triangle Angle-Sum Theorem are triangle theorems
The differences are;
1) The Third Angle Theorem is mainly used to prove the similarity of two triangles, while Triangle Angle-Sum Theorem is used to find the measure of the third angle
2) The value of the third angle may not be determined when using the The Third Angle Theorem to prove the similarities between triangles while the value of the third angle is normally determined calculated when the Triangle Angle-Sum Theorem is used to find the third angle given the other two angles in the triangle

how do you decrease £56 by 14%
Answers
to do this, we have to multiply:
0.14 and 56 together.
0.14 x 56 = 7.84.
Now, we decrease £56 by 14%, which we have found is 7.84.
56 - 7.84 = 48.16.
The answer is 48.16. The process has been shown. Hopefully this helps! (:
x-14%
x=56*14/100
x=7,84£(it’s 14%)
56-7,84=48,16£ or 48 it’s (84% by 56£)

Please help me find all 3 !
Answers
Answer:
m<P = 60 degrees
Step-by-step explanation:
All sides of the triangle are equivalent to each other.
All three sides of the triangle equal 180 degrees total.
Since there are 3 sides, we divide 180 by 3 to find the measurement for all sides
180 ÷ 3 = 60
Q = 60 degrees
P = 60 degrees
R = 60 degrees
Check your work by adding all three sides together to equal 180:
60 + 60 + 60 = 180
180 = 180
Work is correct

A triangle has sides equal to 3, 4, and 5.
Which statement regarding the triangle is correct?
A. The triangle is an equilateral triangle.
B. The triangle is an isosceles triangle.
C. The triangle is an obtuse triangle.
D. The triangle is a right triangle
Answers
Answer:
D
Step-by-step explanation:3,4,5 is a pythagorean triple, making it a right triangle
Answer:
D
Step-by-step explanation:
If you use the Pathagorean theorum where [tex]A^{2}[/tex] + [tex]B^{2}[/tex] = [tex]C^{2}[/tex] and plug in the number you were given, you get [tex]3^{2}[/tex] + [tex]4^{2}[/tex] = [tex]5^{2}[/tex] or 9 + 16 = 25 which is correct.
So this has to be a right triangle.
You can also eliminate answer A because you already know none of the sides are equal so it can't be equilateral.
You can eliminate answer B because you already know that no two sides have an equal length so it can't be defined as isosceles.
You can eliminate answer C because if it were obtuse, the 3rd side (5) would have to be a lot longer.
