Answer:
Approximately 2 weeks
Step-by-step explanation:
Given data
Cost of bike= £250
Assuming she works for 6 days
1.Babysitting
6*2.75=£16.5 per day
for 6 days
=16.5*6
=£99
2. Saturday Job
=£27.50
Total earnings for the week
=£27.50+£99
=£126.5 weekly
Hence it will take her

Describe the graph of the solution to the inequality 8x + 17 ≥ 137
Answer:
Simplifying
8x + 17 = 137
Reorder the terms:
17 + 8x = 137
Solving
17 + 8x = 137
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-17' to each side of the equation.
17 + -17 + 8x = 137 + -17
Combine like terms: 17 + -17 = 0
0 + 8x = 137 + -17
8x = 137 + -17
Combine like terms: 137 + -17 = 120
8x = 120
Divide each side by '8'.
x = 15
Simplifying
x = 15

if you subtract 12 from my number and multiply the difference by -6 the result is -90 what is my number
Answer:
n must be 27
Step-by-step explanation:
Let this number be x. Then -6(n - 12) = -90.
Dividing both sides by -6 yields n - 12 = 15.
Add 12 to both sides.
Then n must be 27.
Check: subtract 12 from 27; this yields 15. Now multiply this result by -6. The result is -90, which was expected.

Y = 3/4x - 3
3x - 4y = 12
1) (4,0)
2) (0,-3)
3) no solution
4) infinite solution
Answer:
2) (0,-3)
Step-by-step explanation:
hello :
put x=0 and y= -3 in this system !
Y = 3/4x - 3
3x - 4y = 12
- 3 = 3/4(0) - 3 means : -3 = -3 ......true
3(0) - 4(-3) = 12 means : 12= 12 ......true

The side of polygone have length 5,7,8,11&9, the perimeter of similar polygone is 75cm ,finde the length of the side of large polygon?
Answer:
The side lengths of the larger polygon are;
15 cm
20.625 cm
16.875 cm
9.375 cm
13.125 cm
Step-by-step explanation:
Firstly, we need to calculate the perimeter of the first polygon
Mathematically, we can get this by adding the side lengths together
We have this as;
5 + 7 + 8 + 11 + 9
= 40 cm
so we have the ratio of the lengths of both as;
75 cm/40 cm = 1.875
Now, we simply will multiply the lengths of the smaller polygon by 1.875
So we have the side lengths of the bigger polygon as;
1.875 * 5 = 9.375 cm
1.875 * 7 = 13.125 cm
1.875 * 8 = 15 cm
1.875 * 9 = 16.875 cm
1.875 * 11 = 20.625 cm

determine the value of k if g(x) =4x+k is a tangent to f(x)= -x² +8x +20
Answer:
22
Step-by-step explanation:
222
The value of k in the given functions is; 24
What is the value of the function to the tangent?
We are given the functions;
g(x) = 4x + k as a tangent to f(x) = -x² +8x +20
For f(x) = -x² +8x +20
=> f'(x) = -2x + 8
Thus, slope of tangent at ( x , y) = -2x + 8
For g(x) = 4x + k
g'(x) = 4.
Thus, slope is 4
Therefore;
-2x + 8 = 4
-2x = -4
x = 2
Putting 2 for x in f(x) gives;
f(2) = -2² + 8(2) + 20
f(2) = 32
Thus, it is at (2 , 32)
Thus, (2 , 32) lies on g(x) = 4x + k
4(2) + k = 32
k = 32 - 8
k = 24

FIND Y IN XYZ, help please
Given:
In triangle [tex]XYZ,m\angle X=90^\circ, m\angle Y=45^\circ, m\angle Z=45^\circ, XZ=y,YZ=15\sqrt{2}[/tex].
To find:
The value of y.
Solution:
In a right angle triangle,

Multiply 6/5 by the reciprocal of (-3/8)
Answer:
-48/15, simplified to -16/5
Step-by-step explanation:
The reciprocal of -3/8 is -8/3. So the equation will be 6/5 x -8/3. Multiply numerators then multiply denominators to get -48/15. This can simplify to -16/5 by dividing both by 3.
Answer:

Plz help me! Before in 7mins.
9514 1404 393
Answer:
A. r = 4
Step-by-step explanation:
For common ratio r, the second term is ...
a2 = 3r
The next terms are ...
a3 = (a2)r = (3r)r = 3r²
a4 = (a3)r = (3r²)r = 3r³ = 192
Then the value of r is ...
r³ = 192/3 = 64
r = ∛64 = 4
The common ratio is r = 4.

Answer:
A
Step-by-step explanation:
a positive number times a negative number is equal to a negative number.
Because all negative numbers have a value less than 0 the inequality sign must face towards the 0
The inequality sign also must be a < or > not a ≤ or ≥ as no positive number times -11 will equal 0
so the answer would be x < 0
