PLEASE HELP I NEED HELP ALSO I WILL MARK BRAINLIEST

Mathematics
1 answer:
BartSMP [9]3 years ago
7 0

Answer:

see below

Step-by-step explanation:

Let C be at (0,0)

D is at (7,12)

The slope is

m = (y2-y1)/(x2-x1)

    = (12-0)/(7-0)

   = 12/7

The equation of the line is y = mx+b where m is the slope and b is the y intercept

y = 12/7x +b

The y intercept is (0,0)

y = 12/7x +0

y = 12/7x

The domain is the input values or the values that x can take

X goes from 0 to 7

Domain: {0≤x≤7}

The range is the output values or the values that y can take

y goes from 0 to 12

Range: {0≤y≤12}

erik drove 439.92 miles on 15.6 gallons of gas. To the nearest hundredth, how many miles could he drive on 39.7 gallons of gas?
Thepotemich [5.8K]
In the question it is already given that Eric drove for 439.92 miles on 15.6 gallons. It is required to find the distance traveled on 39.7 gallons of gas. Also we have to find the answer to the nearest hundredth.
Then,
In 15.6 gallons Eric can drive for a distance = 439.92 miles
In 39.7 gallons Eric can drive for a distance = [(439.92/15.6) * 39.7] miles
                                                                       = 1119.54 miles
So the total distance traveled by Eric is 1120 miles with 39.7 gallons of gas. The answer has been calculated to the nearest hundredth.

Find the area of the figure. please help my teacher is waiting.......
katrin [286]

Answer:

The area of the shape is 89m²

Step-by-step explanation:

You need to subtract the area of the empty triangle from the area of the rectangle.

The rectangle's area is 13m × 8m = 104m²

The triangle's area is (6m × (13 - 8)m) / 2 = (6 × 5) / 2 m² = 15m²

Subtract the triangle's area from the rectangle:

104m² - 15m²

= 89m²

Akayo claims that there are centers of dialstiond through ehich a dialation of line n by a factor of 1.5 leaves line n unchanged
mars1129 [50]

Answer:

See Explanation

Step-by-step explanation:

This question requires further details. In absence of the details, I will answer on a general term.

When a line is dilated (whether expanded or compressed), the new line will be on the same line with the dilated line; however, the length of both lines will be different

Take for instance:

<em>Line AB of coordinate (1,3) is horizontally dilated by 2, </em>

<em>Horizontal dilation rule is: y = f(cx) where c is the dilation factor</em>

<em />

<em>So, the new point will be </em>

<em>A'B' = (1, 3 * 2)</em>

<em>A'B' = (1,6)</em>

<em />

<em>When you compare the x coordinate of both line, you will observe that they have the same x coordinate of 1. </em>

<em>This implies that they are on the same level but different length</em>

<em />

The same is applicable to vertical dilation

<em />

<em>the new point will be:</em>

<em />
