Answer:
(0, 3) lies on the line joining (2, -2) and (-4, 13).
Step-by-step explanation:
The equation of the line joining the points (2, -2) and (-4, 13) is:
-2(y + 2) = 5(x - 2)
-2y - 4 = 5x - 10
5x + 2y - 6 = 0
When we substitute x = 0 and y = 3,
5(0) + 2(3) = 0 + 6 = 6
So, (0, 3) lies on the line joining (2, -2) and (-4, 13).
Answer:
16
Step-by-step explanation:
100/6.25=16
Answer:
y = 41°
Step-by-step explanation:
∡ y and 139° are adjacent angles and sum to 180° , that is
∠ 1 + 139° = 180° ( subtract 139° from both sides )
∠ 1 = 41°
To find the perimeter of the triangle you need to add up all the side lengths
Now move like terms, the ones with x and ones without, next to each other.
(You can skip this step, but I think it makes it easier to understand.)
Now just add like terms to get your answer.
Answer:
c
Step-by-step explanation:
the equation would be C because
A would end up with a negative amount
B is more than she originally has to paint and
D has the wrong coefficient for <em> t</em>.
