Answer:

3,4,5

Step-by-step explanation:

All you have to do is use the Triangle Inequality Theorem, which states that the sum of two side lengths of a triangle is always greater than the third side. If this is true for all three combinations of added side lengths, then you will have a triangle therefore 3,4,5 is not triangle.

Mitchell is a big coffee fan, so he always takes care of coffee brewing at the office. Normally he uses 100 grams of Robusta cof

Lubov Fominskaja [6]

he uses 100 grams for 10 cups

20% more would be 100 *1.20 = 120 grams for 10 cups

15/10 = 1.5

120*1.5 = 180

he needs 180 grams for 15 cups.

Find the equation of a line passing through a point (3,5) and perpendicular to the line joining the points (3, 7) and (7, -1)

eduard

Step-by-step explanation:

we start first by finding the gradient of the line

change in y/change in x

7-(-1)/3-7=8/-4

=-2

then for perpendicular lines m1m2=-1

therefore to find the gradient of that line

-2m2=-1

therefore m2=2

so therefore

y-5/x-3=2

so y-5=2x-6

y-2x=-1

in the form y= mx +c

then y=2x-1

Andrej [43]

Answer:

The solution is the point (3,-2) (intersection point both lines)

Step-by-step explanation:

we have

$y=-2x+4$ -----> equation A

$y=x-5$ -----> equation B

Solve the system by graphing

Remember that

The solution of the system is the intersection point both graphs

using a graphing tool

The solution is the point (3,-2)
