Answer:
y= 2x + (-2)
Step-by-step explanation:
The algebraic formula y=mx+b can be broken down into mx, equaling slope +x, and b, which is the y intercept. Taking two points from the slope, you can see that the slope is 2, as the line moves up 2 on the y axis for every 1 move horizontally on the x axis. Additionally, we see that this particular line crosses the y axis at the point (-2), meaning that is the y intercept. Hope this can offer some assistance.
First problem: draw a line segment through the vertex R and a point C on PQ such that the segment is perpendicular to PQ, thus forming an altitude of the triangle. This new segment CR, the new segment CP, and PR form a 30-60-90 right triangle, where the measure of angle PCR is 90 degrees. CR then occurs with PR in a ratio of
to 2, so
and this can be considered the height of a triangle whose base is PQ. The area is then
Second problem: the sum of the interior angles of any triangle is 180, so the measure of the missing angle must be 180 - 20 - 35 = 125 degrees. By the law of sines, the length of the missing side (call it
) satisfies
Use Heron's formula to find the area of the triangle:
where
is the area,
are the lengths of the sides, and
is the half the perimeter of the triangle. Then the area is about
square feet. Convert to square yards:
then round up to 7 square yards. At a price of $12.50 per square yard, the total price will be $87.50.
We are given function: f(x) = 12x+3.
Generally we start x from 0 and we can take any number for x to get some real number of f(x).
Therefore, domain of the function start from 0.
And we can take any number 0 or greater than 0 to get some value of f(x).
So, we can say that domain of the function is " All real numbers greater than or equal to 0".
<h3>Therefore, Prectical domain : All real numbers greater than or equal to 0.</h3>

Given that cost of each sandwich is AED 22 .50 .Also there is a delivery charge of AED 10 .
Also , it is given that total cost should be represented by t and sandwiches by s .
So , if one sandwich costs AED 22.50 .
Then , s sandwich will cost 22.50 × s = AED 22.50s.
Now , there is a delivery charge of AED 10 .
So , the total cost will be AED ( 22.50s + 10 ) .
And as per Question , it equals to t .
Hence the required equⁿ will be ,
2) If one sandwich costs AED 22.50 then 10 will cost 22.50 × 10 = AED225
