Which equation represents a line that passes though (5, 1) and has a slope of 1/2?

Mathematics
1 answer:
Archy [21]3 years ago
4 0

Answer:

\large\boxed{y-1=\dfrac{1}{2}(x-5)\leftarrow\text{point-slope form}}\\\boxed{y=\dfrac{1}{2}x-\dfrac{3}{2}\leftarrow\text{slope-intercept form}}\\\boxed{x-2y=3\leftarrow\text{standard form}}

Step-by-step explanation:

The point-slope of an equation of a line:

y-y_1=m(x-x_1)

We have

the point (5,\ 1)\to x_1=5,\ y_1=1

and the slope m=\dfrac{1}{2}

Substitute:

y-1=\dfrac{1}{2}(x-5)          <em>use distributive property</em>

y-1=\dfrac{1}{2}x-\dfrac{5}{2}       <em>add 1 to both sides</em>

y=\dfrac{1}{2}x-\dfrac{3}{2}        <em>multiply both sides by 2</em>

2y=x-3               <em>subtract x from both sides</em>

-x+2y=-3            <em>change the signs</em>

x-2y=3

The figure below has to be covered with multi-colored cloth. What is the area of the cloth in sq mm that is needed?
Georgia [21]

Answer:

26,250 sq mm^2

Step-by-step explanation:

First i cut the shape so its a rectangle on the top and there is a vertical rectangle. Then you find the lengths and to do that for the first rectangle(the horizontal one) you add 75, 75 and 75 to get the length. Then multiply 225(the sum of the 3 75s) by 75 (width) which gets you 16,875.

That is the area of the first rectangle

Now for the vertical rectangle you simply multiply the length and width, 75x125. That equals 9,375. Now add.

9375+16875= 26250!!!!

Oneta writes an algebraic expression with three terms. The y-term has a coefficient of -3, and the x-term has a coefficient of 1

X - 3y + z

Another term would be the 3rd term which would be working with 3d planes instead of 2d planes.

Can someone answer this question please please help me I really need it if it’s correct I will mark you brainliest .
sergey [27]

Step 1) Divide the figure into separate shapes

Long rectangle: 27 x 5

Triangle: 3 x 4

Middle rectangle: 15 x 7

Small rectangle: 6 x 3

Step 2) Find the area of each shape

Long rectangle: A = 27 x 5 = 135

Triangle: A = 1/2 x 3 x 4 = 6

Middle rectangle: A = 15 x 7 = 105

Small rectangle: 6 x 3 = 18

Step 3) Add all of the areas together

A = 135 + 6 + 105 + 18 = 264 square feet

Hope this helps! :)
