equation of line passing through (1,-7)( -4,8)
First let's find slope (m)
m = (8+7)/(-4-1)
= 15/-5 = -3
(x1,y1) = (1,-7)
Plugging above value in
y - y1 = m( x-x1)
y+7 = -3( x-1)
y+7 = -3x +3
y+3x +4=0
Answer:
6:5
Step-by-step explanation:
I am thinking it would be 6:5 because you have 6 dogs, and 5 cats. So, you could think of it as for every 6 dogs you have 5 cats at the kennel.
Answer:
A triangle's exterior angle is the angle established by one of the triangle's sides and the extension of one of the triangle's adjacent sides.
Step-by-step explanation:
FACTS:
Each vertex of a triangle has two exterior angles.
It's worth noting that the "outside" angles that are "vertical" to the angles inside the triangle aren't called to as triangle exterior angles.
1. The given triangle's angles are 1, 5, and 6.
2. Angle 3 is perpendicular to angle 5 on the inside.
3. The triangle's outside angles are 2 and 4.
The correct answers are A and B.
A triangle's exterior angle is the angle created by one of the triangle's sides and the extension of one of the triangle's adjacent sides.
Answer:
<u>There were 257 children and 365 adults at the public pool.</u>
Step-by-step explanation:
Let the number of children and adult be x and y respectively,
x+y = 622
1.5x+2y = 1115
Now,
x+y = 622
or, x = 622 - y
Now,
1.5x + 2y= 1115
or, 1.5(622-y) + 2y = 1115
or, 933 - 1.5y + 2y = 1115
or, 933 + 0.5y = 1115
or, 0.5y = 1115-933
or, 0.5y = 182
so, y = 182/0.5
so, y = 365
Now,
x+y = 622
or, x + 365 = 622
so, x = 257
