Please help! tell whether x and y are proportional. if so, identify the constant of proportionality
sesenic [268]

Answer:

y = (1/2)x is proportional; (1/2)

Step-by-step explanation:

1. y= 1/2x   Proportional; constant of proportionality is 1/2.

2. y=2x + 7   Not proportional because of the non-zero y-intercept.

3. x= y + 2    Not proportional (same a reason as for #2)

For this question you can say:
5/9( °F - 32) = -10 °C
so now you should solve the equation:
5F/9 - 160/9 = -10 
⇒ 5F/9 = -10 + 160/9 ⇒ 5F/9 = -90/9 + 160/9 ⇒ 5F/9 = 70/9 ⇒ now you can multiply both sides of the equation by 9 so you will have:
5F = 70 ⇒ F = 14 ° F :)))

Plllllllease helpppppp

Answer:

Step-by-step explanation:

b/c we know that these triangles both have equal sides... that is given that <u>ab</u> and<u> be</u> are the same length.   and that <u>be </u>and <u>cd</u> are parallel , we know that they both are isosceles triangles and that the base angles are the same.  The side on <u> ad </u>and<u> ae</u>  have equal angles.

so we can make the equation

2a +56 = 180  (b/c we know that around a triangle it's 180°

2 a = 124

a = 62

so ∠ BAE = 62°
