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 =
= - 
y = -
x ← equation of proportionality
when y = 4, then
4 = -
x (multiply both sides by - 4 )
x = - 16
Answer:
B' (2, 5 )
Step-by-step explanation:
Under a counterclockwise rotation about the origin of 270°
a point (x, y ) → (y, - x ) , then
B(- 5, 2 ) → B' (2, 5 )
For this case we must find the value of the following expression:

When:

Substituting the given values we have:

Finally, the value of the expression is 394.
Answer:
The value of the expression is 394.
Answer:
96 + 150 + 2x + x = 360⁰
240 + 3x = 360⁰
3x = 120
x = 40⁰ hope it's help you
189.
3*1=34 --> split this into two parts. 3*1 is 3 and 3+1 is 4 so put them together and you get 34.
