A proportional relationship is formed when y=1 and x=-4 what is the value of x when y=4

Mathematics

Answer:

x = - 16

Step-by-step explanation:

The equation relating two proportional quantities is

y = kx ← k is the constant of proportionality

To find k use the condition when y = 1, x = - 4

k = \frac{y}{x} = - \frac{1}{4}

y = - \frac{1}{4} x ← equation of proportionality

when y = 4, then

4 = - \frac{1}{4} x (multiply both sides by - 4 )

x = - 16

The point D(2, -5) is rotated 90° counterclockwise around the origin. What are the coordinates of the resulting point, D′?
jeyben [28]

Answer:

D' = (5, 2)

Step-by-step explanation:

Try to join D and the origin using a line. Counterclockwise means in an opposite direction of rotation of the clock hands. So draw another line towards the right which is perpendicular to the previous line to fine the answer. Remember the length of the lines should be equal.

What is the value of x ?
valina [46]

Answer:

The value of x = 9

Step-by-step explanation:

∵ The figure has right angle and a line ⊥ from the right angle to the hypotenuse

∴ There is a relation between the ⊥ line and the two parts of the hypotenuse

∴ (⊥)² = multiplication of the two parts of the hypotenuse

∴ (6)²= 4 × x

∴ 36 = 4 × x

∴ x = 36/4 = 9
