Answer:
x=20. y=15
Step-by-step explanation:
in similar triangles the sides are all in proportion. this means:
so:
x=5×4
x=20
and...
y=3×5
y=15
Divide distance walked by time:
2 1/4 miles / 2/3 hours = 3 3/8 miles per hour
REMEMBER: A rotation of 180 degrees means you flip both x and y numbers
E(-4,3)
F(7,-5)
G(-2,-8)
Answer:
9.2
Step-by-step explanation:
we can use the pythagorean theorem to find the hypotenuse between the centre of the circle and the midpoint of the line segment.
hence,
x = sqrt(36 + 49)
x = 9.21
<h2>
x = 2 and y = - 3</h2>
Step-by-step explanation:
The given system of linear equations:
x - 2y = 8 ........ (1)
and 4x + y = 5 ........ (2)
To find, the values of x and y = ?
Multiplying equation (2) by 2, we get
2(4x + y) = 5 × 2
⇒ 8x + 2y = 10 ........ (3)
Adding equations (1) and (3), we get
x - 2y + (8x + 2y) = 8 + 10
⇒ x - 2y + 8x + 2y = 8 + 10
⇒ 9x = 18
⇒ x = 2
Put x = 2 in (1), we get
2 - 2y = 8
⇒ 2y =2 - 8
⇒ 2y = - 6
⇒ y = - 3
∴ x = 2 and y = - 3
