First, change one of the equations to an y=x form I'll use the top one for example.
3x-2y=14
-2y=14-3x
y=-7+(3/2)x
Not that you can show what y is in terms of x, plug in the x side of the equation into the other equation, for y.
x+2(-7+(3/2)x)=10
Now, you can solve for x
x-14+3x=10
4x-14=10
4x=24
x=6
Using this value of x, we can now solve for y using one of the original equations.
(6)+2y=10
2y=4
y=2
Answer:
Step-by-step explanation:
We have been given that the vertices of a triangle are A (5, 0), B (x, y) and C (25, 0). We are asked to find the area of the given triangle.
We will use area formula for triangle with vertices A, B and C as given below:
Upon substituting the given coordinates of points A, B and C in above formula, we will get:
Therefore, the area of the given triangle would be .
Answer:
Distance = 4 miles
Displacement = 0
Step-by-step explanation:
Given that :
Speed of honey bee = 4mph
Total travel time = 1 hour
Distance traveled by the honey bee:
Distance traveled = speed * time
Distance traveled = 4mph * 1 hour
Distance traveled = 4 miles
Displacement = 0 miles ; change in distance from initial position.
Since initial position of the honeybee is the beehive and its final position is the beehive. Hence, the change from its initial position is zero
Yes use that example and it will help!
Answer:
7 1/5 cm
Step-by-step explanation:
45/27 = 12/x
x = 12*27 / 45
x = 324/45
x = 7 9/45
= 7 1/5
