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

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

A store is going out of business. Everything is marked down 40%. How much do you pay now for an item that used to cost $150? Explain how you got your answer.

Answers

Answer:

You would pay $90 now for an item that used to cost $150.

Step-by-step explanation:

Here's how I thought of it. There are two ways to solve this problem.

Because we know that the item is discounted by 40%, that leaves 60% of its price left. (100% price - 40% price = 60% price).

Thus, you would multiply $150 by 0.6 (or, 60% in decimal form), which equals $90.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Alternatively, you could also multiply $150 by 0.4 and just subtract what you get from the total. That number is 60, and $150 - $60 = $90.

Use whichever way makes more sense to you!

What degree of rotation about the origin will cause the triangle below to map
onto itself?

A. 360°
B.90
C.180
D.270

Answers

A is the answer as it will go in a full circle in order to map onto itself

The degree of rotation about the origin will cause the triangle below to map onto itself is 360 degree.

Option A is correct.

What is Transformation?

A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object. Pre-Image refers to the object's initial shape, and Image, after transformation, refers to the object's ultimate shape and location.

In the figure ABCD, is transformed to figure A'B'C'D'.

A figure will be mapped onto itself if it circles the graph 360 degrees.

As there are 360 degrees in a circle, the figure has just completed a full circle and returned to where it was before rotating.

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
