Parallel lines have the same slop, but different y-intercepts.
The new equation is y = 4/3 x + b
Now substitute x and y for the point's coordinates...
-4 = 4/3 (3) + b
(solve for b)
-4 = 12/3 + b
-4 = 4 + b
b = -8
The final equation is:
y = 4/3 x - 8
In point-slope form, this is B

The radius of the base of the cylinder is 2x cm and the height of the cylinder is h cm.
The radius of the sphere is 3x cm.
The volume of the cylinder is equal to the volume of the sphere.
Express h in terms of x. Give your answer in its simplest form.
Answers
Answer:
h = 9x
Step-by-step explanation:
Given: i. for the cylinder, base radius = 2x cm, height = h cm
ii. for the sphere, radius = 3x cm
iii. volume of the cylinder = volume of the sphere
volume of a cylinder is given as;
volume = [tex]\frac{1}{3}[/tex][tex]\pi[/tex][tex]r^{2}[/tex]h
where: r is its base radius and h the height
volume of the given cylinder = [tex]\frac{1}{3}[/tex][tex]\pi[/tex] x [tex](2x)^{2}[/tex] x h
= [tex]\frac{1}{3}[/tex][tex]\pi[/tex] x 4[tex]x^{2}[/tex] x h
= [tex]\frac{4}{3}[/tex][tex]\pi[/tex][tex]x^{2}[/tex] h
volume of a sphere = [tex]\frac{4}{3}[/tex][tex]\pi[/tex][tex]r^{3}[/tex]
where r is the radius.
volume of the given sphere = [tex]\frac{4}{3}[/tex][tex]\pi[/tex] x [tex](3x)^{3}[/tex]
= [tex]\frac{4}{3}[/tex][tex]\pi[/tex] x 9 [tex]x^{3}[/tex]
= 12[tex]\pi[/tex][tex]x^{3}[/tex]
Since,
volume of the cylinder = volume of the sphere
Then we have;
[tex]\frac{4}{3}[/tex][tex]\pi[/tex][tex]x^{2}[/tex] h = 12[tex]\pi[/tex][tex]x^{3}[/tex]
4[tex]\pi[/tex][tex]x^{2}[/tex] h = 36[tex]\pi[/tex][tex]x^{3}[/tex]
subtract [tex]x^{2}[/tex] from both sides
4[tex]\pi[/tex]h = 36[tex]\pi[/tex]x
divide both sides by 4[tex]\pi[/tex]
h = [tex]\frac{36\pi x}{4\pi }[/tex]
= 9x
h = 9x

Nick and June win some money and share it in the ratio 5:3. Nick gets £26 more than June.
How much did June get?
Answers
Answer:
£39
Step-by-step explanation:
Nick and June wins some money and share in the ratio 5:3
The difference = 5-3
= 2
Since Nicki receives £26 and his shares is 2
= 26/2
= 13
Therefore June shares can be calculated as follows
= 3×13
= 39
Hence June shares is £39

Step 1: Define
16 < -2(x + 4)
Step 2: Solve for x
Distribute -2: 16 < -2x - 8Add 8 to both sides: 24 < -2xDivide -2 on both sides: -12 > xRewrite: x < -12Here we see that any number x smaller than -12 would work as a solution to the inequality.
The speed of a boat in still water is 40 mph. If it takes the same time for the boat to travel 8 miles upstream as it does to travel 24 miles downstream, then what is the speed of the current? Brainly
Answers
Answer:
Current speed is 40mph
Step-by-step explanation:
We firstly need to know what is intended by upstream and downstream. When the boat travels in the direction of the current (horizontal movement of the water), we say it is moving downstream otherwise it is moving upstream.
Let's assume the speed of the boat is A and that of the current is B, then the speed when it moves dowstream would be A + B and the speed if it moves upstream would be A – B.
In this question, we know that the speed of the boat is 40mph. Given that it takes the same time to travel 8miles upstream as it does to travel 24miles downstream, we have
Speed upstream = 8/t
Speed downstream = 24/t
Respectively.
Let speed of current be X, then
Speed downstream = 40 + X
Speed upstream = 40 – X
From the question we have:
(40 + x)/24 = (40 – X)/8
(40 + x)/3 = (40 – x)/1
3(40 – x) = 40 + X
120 – 3x = 40 – X
120 – 40 = 3x – X
2x = 80
X = 40.
Therefore, current speed is 40mph
