Answer:
C. y=5x+14
Step-by-step explanation:
Solve using this formula: y=mx+b
4 = (5) (-2) + b
4 = -10 + b
+10 +10
14 = b
Then you will plug in what you found for b in:

© Angad and Nick win some money and share it in the ratio 5:1. Angad gets £60 more than Nick.
How much did Nick get?
Answer:
£15
Step-by-step explanation:
Angad : Nick = 5 : 1
Let
Nick share = x
Angad share = x + £60
Angad : Nick
5 : 1 = x + £60 : x
5/1 = x + 60 / x
Cross product
5 * x = 1 * x + 60
5x = x + 60
5x - x = 60
4x = 60
x = 60/4
x = 15

11 is B and 12 is B. 11 is B because perimeter means to add all the outside values of the shape. 2.5+5+4+1 and then there are two missing side values which are 1.5 and 1, add them all together and the perimeter is 15. For the area, separate the small square with the big rectangle to have two full shapes. The area of the rectangle is 4x2.5=10. Area of the small square is 1x1=1. 10+1=11.

Directed line segment overline FG has endpoints F(4, 9) and G(- 8, - 9) .On the coordinate plane below , plot a point that partitions the directed line segment in a ratio of Point 1/2 Undo Reda x Reset 10 8 7 65 443 2
Answer:
The coordinates of the point that makes the division in the given ratio is (0,3)
Step-by-step explanation:
Here, we want to find the point on the line segment that divides the line segment in the ratio 1:2
We simply use the internal division formula
That would be;
(x,y) = (nx1 + mx2)/(m + n) , (ny1 + my2)/(m + n)
m = 1 and n = 2
(x1,y1) = (4,9)
(x2,y2) = (-8,-9)
Substituting these values into the formula, we have;
2(4) + 1(-8)/(1 + 2) , 2(9) + 1(-9)/(2 + 1)
= (8-8)/3 , (18-9)/3
= (0,3)

AB is parallel to CD
Find the value of X
Find the value of Y
Answer:
∠y° = ∠69°
∠x = ∠69°
Step-by-step explanation:
1) The question relates to parallel line theorem
The given parameters are;
AB is parallel to CD
∠111° and ∠y° are consecutive interior angles
∠69° and ∠x° are alternate interior angles
When two parallel lines are crossed by a common transversal, the consecutive interior angles are supplementary (sum up to 180°), and the alternate interior angles are equal
Therefore, we have;
∠111° + ∠y° = 180°
∠y° = 180° - ∠111° = ∠69°
∠y° = ∠69°
2) For the alternate interior angles, ∠69° and ∠x°, we have;
Alternate angles are equal, therefore ∠x = ∠69°
10 boys clear a piece of land in 21 days. How many days will it take 7 boys to clear the same land at the same rate
Pls i need answer fast
Given:
10 boys clear a piece of land in 21 days.
To find:
The number of days it will take 7 boys to clear the same land at the same rate.
Solution:
We have,
10 boys clear a piece of land in 21 days.
Total work = [tex]10\times 21[/tex]
= [tex]210[/tex]
Let 7 boys clear the same piece of land in x days.
Total work = [tex]7\times x[/tex]
= [tex]7x[/tex]
Now, the total work is same.
[tex]7x=210[/tex]
Divide both sides by 7.
[tex]x=\dfrac{210}{7}[/tex]
[tex]x=30[/tex]
Therefore, 7 boys clear the same piece of land in 30 days.

Step-by-step explanation:
Here, we want to write the final formula for the equation after performing the given transformations
Reflection on the y-axis means the x-axis value will change sign
that will give:
y = -x^1/3
Transition of 3 units in the positive x axis
mathematically, we are adding 3 to x
so we have
y = -(x+3)^1/3
4 units in the negative y direction means we are subtracting 4 from the whole equation
That means;
y = -(x + 3)^1/3 - 4
This shows that the first option is right
please help me understand
Answer:
x=4
y=6
Step-by-step explanation:
We need to find value of x and y if RS bisects AB and RS = 28
We are given: RS = 28
and We can see from figure that: RT= 3y-7 and TS = 2y+5
And we can observe that RT + TS = 36
So, putting all the values, we can find value of y
[tex]3y-7+2y+5=28[/tex]
Solving this equation, will find value of y
[tex]3y+2y+5-7=28\\5y-2=28\\5y=28+2\\5y=30\\y=\frac{30}{5}\\y=6[/tex]
So, we get value of y: y=6
Now, we also know that RS bisects the line AB. It means it divides both the lines equally.
So, we can write: AT = TB
Putting values we can find value of x
We have AT = 4x-2
TB = 4y+2
and y =6
[tex]4x-2 = 4y+2\\4x-2=4(6)+2\\4x-2=12+2\\4x=14+2\\4x=16\\x=\frac{16}{4}\\x=4[/tex]
So, we get value of x: x=4
The mean of 5 numbers is 6.
The numbers are in the ratio 1 : 3 : 3 : 4 : 4.
Find the numbers.
Answer:
2, 6, 6, 8, 8
Step-by-step explanation:
First, we know that the mean is the sum of the number divided by the amount, so if we take the answer we have, 6, and multiply that by the amount of number, 5, then we get 30.
Now we add the numbers in the ratio, so 1 + 3 + 3 + 4 + 4 = 15
15 x 2 = 30
This means we need multiply the numbers in the ratio by 2 to get
2 + 6 + 6 + 8 + 8 = 30
Answer:
2, 6, 6, 8, 8
Step-by-step explanation:
The mean is calculated as
mean = [tex]\frac{sum}{count}[/tex], thus
[tex]\frac{sum}{5}[/tex] = 6 ( multiply both sides by 5 )
sum = 30
sum the parts of the ratio, 1 + 3 + 3 + 4 + 4 = 15 parts
30 ÷ 15 = 2 ← value of 1 part of the ratio, thus
3 parts = 3 × 2 = 6
4 parts = 4 × 2 = 8
Thus the 5 numbers are
2, 6, 6, 8, 8
