Answer:
y=8/5x-4
Step-by-step explanation:
1:find the slope
[tex]\frac{4+4}{5-0} =\frac{8}{5}[/tex]
slope/m=8/5
2: solve for b using Y=mx+b
plug in the numbers to find b (the x and y get from one set of the points your given and the m is the slope)
Y=mx+b
y=4
m=8/5
x=5
4=8/5(5)+b
4=8+b
-4=b
than to put all the in y=mx+b form just plug in the b and m
Bridget, Brian & Caroline share some money in the ratio 4 : 9 : 4.In total, Bridget and Caroline receive £48.How much does Brian get?
Answer:
£54
Step-by-step explanation:
According to the ratio:
Bridget = 4/17
Brian = 9/17
Caroline = 4/17
____
So if Bridget and Caroline receive £48, that would mean £48 is 8/17 of the total amount. We can find 1/17 of the money by dividing £48 by 8.
48 / 8 = 6
And then multiply that by 9 to find 9/17 of the money (the amount Brian has).
6 x 9 = 54

Line K has a slope of -5. Line j is perpendicular to line k and passes through the point (5, 9). Create the equation for line j. (Please help me)
Answer:
y = 1/5 x + 8
Step-by-step explanation:
slope of line j: m = -(1/-5) = 1/5
j pass (5,9): (y-9)/(x-5) = 1/5
y-9 = 1/5(x-5) = 1/5 x - 1
y = 1/5 x + 8

The dataset is given as:

Find the perimeter and area of the shape based on the information provided.
Answer:
Area of the shape=241.2cm^2
Perimeter of the shape=76.08cm
Step-by-step explanation:
Find the base for the first triangle = tan(75°)=O/A
= A=30/tan(75°)
=A = 8.04cm (2decimal place)
Area of first triangle= 1/2×Base×height

3y + 15 = 2x + 15 =
Answer:
x = 3/2y
y = 2/3x
Step-by-step explanation:
x = 3/2y
Swap sides so that all variable terms are on the left hand side
2x + 15 = 3y + 15
Subtract 15 from both sides
2x = 3y + 15 - 15
Subtract 15 from 15 to get 0
2x = 3y
Divide both sides by 2
2x/2= 3y/2
Dividing by 2 undoes the multiplication by 2
X = 3y/2
Y = 2/3x
Subtract 15 from both sides
3y = 2x + 15 - 15
Subtract 15 from 15 to get 0
3y = 2x
Divide both sides by 3
3/3y = 2/3x
Dividing by 3 undoes the multiplication by 3
y = 2/3x

Nancy has 3 necklaces of different lengths. When placed in a stretched out line, they are 445
mm long. Necklace A is 45 mm longer than Necklace B, and Necklace B is half as long as
Necklace C. How long is Necklace A?
The given relationships is that Necklace B is the shortest of the 3
necklaces and Necklace C would be the longest.
Necklace A is 145 mm longReasons:
The number of necklaces = 3
Sum of the lengths of the necklaces = 445 mm
Length of Necklace A = 45 mm + Length of Necklace B
[tex]\displaystyle Length \ of \ Necklace \ B = \mathbf{\frac{Length \ of \ Necklace \ C}{2}}[/tex]
Required:
The length of Necklace A
Solution:
Let A represent Necklace A, B represent Necklace B, and C represent
Necklace C, we have;
A + B + C = 445
A = B + 45
[tex]\displaystyle B = \frac{C}{2}[/tex]
Therefore;
B = A - 45
2×B = C
2 × (A - 45) = C
Which gives;
A + A - 45 + 2 × (A - 45) = 445
4·A - 135 = 445
[tex]\displaystyle A = \frac{445 + 135}{4} = \mathbf{145}[/tex]
The length of Necklace A = 145 mm

Roberto works in a home appliance store she is paid $195 per week and 3% on all sales over $1000 during one year her average weekly sales were $7800 about how much did she earned weekly? about how much did she earned during the year?
Step-by-step explanation:
she gets $195 per week plus 3% on sale OVER $1000.
ok. so, her weekly sales were $7800.
that means we need to calculate 3% of ... $6800 !
as she gets the commission only on sales that are over $1000.
6800 = 100%
1% = 100%/100 = 6800/100 = 68
3% = 1%×3 = 68×3 = $204
so, she earned $195 + $204 = $399 per week
and as there are 52 weeks per year, she then earned
399×52 = $20,748 per year.
Which rational number equals 0 point 6 with bar over 6? (5 points) a 2 over 3 b 6 over 10 c 4 over 5 d 6 over 5

Answer:
a. 2/3
Step-by-step explanation:
The bar over the 6 means the digit is repeated indefinitely. A bit of algebra can turn a repeating decimal into a fraction. Let x represent the value of the repeating decimal.
[tex]x=0.6\overline{6}\\\\10x=6.6\overline{6}\\\\10x-x=6.6\overline{6}-0.6\overline{6}\\\\9x=6\\\\x=\dfrac{6}{9}=\boxed{\dfrac{2}{3}}[/tex]

The attachment shows the long division of 2/3 gives a repeating decimal with a repeating digit of 6. You can tell the quotient repeats when the new dividend (after subtraction) is equal to a dividend you have seen before. In this case, the dividend is repeatedly 20, and the quotient digit is repeatedly 6.
The point of the long division is to show you that 2/3 is the correct answer choice for a rational number equivalent to 0.666...(repeating).

Step-by-step explanation:
y directly proportional to X
y=kx
when k is constant
y is 25 and X is 120
25=k120
divide both sides by 120
25/120
k=25/120
there fore the law connecting is 25/120
what is the value of y when x = 72? 25/120*72=3
