Find the slope of the line.
Answer:
The slope is y = x
Step-by-step explanation:
You can find the slope by using the rise over run method with two points.Let's take (1,1) and (2,2). From the first point to the second point, (1,1) goes up one unit and to the right one unit.So the rise over run is 1/1, or 1, which means the slope is 1.
Answer:
m = 1x
Step-by-step explanation:
This is the easiest slope you'll ever have to calculate - if you even need to as it's self explanatory looking at it! Slope = rise/run, thus slope = 1/1 = 1.

the circumcenter of a triangle is equidistant from the
Answer:
The circumcenter of a triangle is a point that is equidistant from all three vertices. The circumscribed circle is a circle whose center is the circumcenter and whose circumference passes through all three vertices.
Step-by-step explanation:
We can conclude that the circumcenter of a triangle is equidistant from the three vertices of the triangle.
What is the Circumcenter of a Triangle?The circumcenter of a triangle can be said to be a point where all three perpendicular bisectors of the sides of the triangle intersect. At this point, all three vertices of the triangle are equidistant.
This means that, each vertices are far from the circumcenter at equal distance.
Therefore, we can conclude that the circumcenter of a triangle is equidistant from the three vertices of the triangle.

the ratio of a shorter walkway to a longer walkway is 3 to 5. the lenght of the sorter walkway is 45 meters. what is the lenght of the longer walkway
Answer:
75 mStep-by-step explanation:
Let s- shorter walkway, l- longer walkway.
Given:
s/l = 3/5s = 45 mFind the length of l:
45/l = 3/5l = 45*5/3l = 75 mAnswer:
[tex]\sf\longmapsto \: length = 75 \: metres[/tex]
Step-by-step explanation:
Now let's find out what's the length of the long walkway–
[tex]\sf\longmapsto \: \frac{3}{5} = \frac{45}{\: length\: of \:longer\: walkway} [/tex]
[tex]\sf\longmapsto \: \: length\: of \:longer\: walkway= \frac{45 \times \: 5 }{3} [/tex]

Finn is walking on a treadmill at a constant pace for 30 minutes. She has programmed the treadmill for a 2-mile walk. The display counts backward to show the distance remaining. Enter and graph the equation that gives the distance f(x) left in miles as a function of the number x of minutes she has been walking. Then, find and compete the interpretation of the x- and y-intercepts. The equation is f(x) =
30*2=15miles per min. x*y=d.
Answer:
The equation is
[tex]f(x) = - \frac{2}{30} x + 2[/tex]
Step-by-step explanation:
since the function is
[tex]f(x) = - \frac{2}{30} x + 2[/tex]
The y-intercept is 2 and the x-intercept is 30.
since the treadmill is counting down the slope of the function would be negative. she set the treadmill for 2 minute walk so at 0 minutes she has 2 minutes left. as the treadmill counts down at the 30-minute mark she will have zero minutes left.

Answer: 3.5 years
Step-by-step explanation: Let A be the salaries earned from company A for x years and B for company B for the same years.
A = 31000 + n*3000
B = 38000 + n*1000
To find the case where A = b, set them to each other and solve for n, the number of years.
31000 + n*3000 = 38000 + n*1000
2000n = 7000
n = (7000/2000) = 3.5 years.

find three consecutive even integers whose sum 72
22, 24, 26
Step-by-step explanation:
2n - 2 + 2n + 2n + 2 = 72
6n = 72
n = 72/6
n = 12
∴ so three consecutive even integers whose sum is 72 :
2n - 2
= 2(12) - 2
= 24 - 2
= 22
2n
= 2(12)
= 24
2n + 2
= 2(12) + 2
= 24 + 2
= 26
verification
22 + 24 + 26
= 46 + 26
= 72 ✓✓

Answer:
y = 1.5x + 9
(y = height; x = number of cups)
Step-by-step explanation:
let x = number of cups
let y = height of the stack
the first cup will add 9 to the height (7.5 + 1.5)
so 9 is the y-intercept
for each additional cup, 1.5 will be added
so y = 1.5x + 9
is 9:2 equivalent to 18:4
Answer:
That is true
Step-by-step explanation:
9:2 = 18:4
9x2=18
2x2=4
Thus, this answer is true.
Answer:
Yes, because if you simplify 18:4, it would simplify to 9/2. Both ratios are equivalent.
