Answer:
Option B
Step-by-step explanation:
→ Find 2 coordinates through which the line passes through
( -2 , -5 ) and ( 0 , -1 )
→ Work out the gradient
[tex]\frac{-1--5}{0--2} =2[/tex]
→ Write into y = mx + c
y = 2x + c
→ Substitute in the coordinates ( 0 , -1 )
-1 = 0 + c so c = -1
→ Write equation
y = 2x - 1
→ Expand out all the equations and simply to see which gives y = 2x - 1
Option B

Suppose that y varies directly with x and y = 3 when x = 9. What is y when x = 18?
Answer:
y = 6
Step-by-step explanation:
Use the direct variation equation, y = kx
Plug in y = 3 and x = 9, and solve for k
y = kx
3 = k(9)
1/3 = k
So, the equation is y = 1/3x
Plug in 18 as x and solve for y
y = 1/3x
y = 1/3(18)
y = 6
So, when x = 18, y = 6

A water park charges an entrance fee of $15 and $3 for each ride. Select the function that models the relationship between the total amount spent (A) and the number of rides purchased (n).
A. A= 15n+ 18
B. A= 15n+3
C. A= 3n+18
D. A=3n+ 15 X
Answer:
D. A = 3n + 15
Step-by-step explanation:
3 should be beside the n variable because n represents each ride that was purchased.
As 15 represents the fee
The A variable represents the total amount spent
Therefore your answer is D.

[x-2]/4=[3x-7]/10 its x-2 dived by 4 not 2/4 same with other side
Answer:
x = 4
Step-by-step explanation:
Given
[tex]\frac{x-2}{4}[/tex] = [tex]\frac{3x-7}{10}[/tex] ( cross- multiply )
4(3x - 7) = 10(x - 2) ← distribute parenthesis on both sides )
12x - 28 = 10x - 20 ( subtract 10x from both sides )
2x - 28 = - 20 ( add 28 to both sides )
2x = 8 ( divide both sides by 2 )
x = 4
A wallet costs $50 to produce. If the manufacturer wants a 70% markup based on cost, what should be the selling price of the wallet?
I need help pls and no files ok pls no files
Answer:
$2,725
Step-by-step explanation:
The maximum number of days is 7.
The cost per days is $375.
The cost for 7 days is 7 * $375 = $2,625.
The owner applies a $100 fee for cleaning which must be added to the cost of the days.
$2,625 + $100 = $2,725
The greatest value for the range is the greatest cost there can be which is $2,725.

Answer:
3x-13+2x+4=116( the sum of two interior angle is epual to the sum of exterior angle )
5x =116-9
5x=107
x=21.4 degree
then
angle a= 3*21.4-13
a=51.2degree
angle b=2*21.4+2
b =44.8degree

20 POINTS HELPIf these two rectangles are similar, what is the measure of the missing length d ?
Answer:
d (or V in the picture) = 16
Step-by-step explanation:
Because the two triangle are similar, the ratios of each of the side lengths should be equal. Therefore, 8/1 should be equal to d/2.
1.) Set up equality of ratios: 8/1 = d/2
2.) Cross multiply: 8*2 = d*1
3.) 16 = d
What is the surface area of a fear with a diameter of 2.7 inches? Use 3.14 for π
Answer:

Step-by-step explanation:
SA of a sphere = 4 π [tex]r^{2}[/tex]
r = 2.7 / 2 = 1.35
4 x 3.14 x [tex]1.35^{2}[/tex] = 22.8906
PLS HELP WITH THIS ONE if a radius of a cake is 13 and the ribbon of the cake is 36 cm will the ribbon be long enough to go around the edge of the cake?
Answer:
No, the ribbon would not be long enough to go around the edge of the cake.
Circumference ≈ 81.7 cm
Step-by-step explanation:
1) Calculate the circumference of the cake
Circumference - the length around a circle
[tex]C=2\pi r[/tex] where r is the radius
Plug 13 in as the radius
[tex]C=2\pi (13)\\C=26\pi\\C= 81.7[/tex]
Therefore, the circumference of the cake is approximately 81.7 cm.
Because the ribbon is only 36 cm long, it would not be enough to go around the edge of the cake.
I hope this helps!
