Answer:
24.24
Step-by-step explanation:
brainlist plzzzzzzzzzzz
Given : y = -25 and x = -5
We can notice that if we Multiply 'x' with 5 we get 'y'
That is (-5) × 5 = -25
⇒ x multiplied by 5 = y
(a) The Equation that relates x and y is 5x = y
(b) We found that the Equation of this Direct variation is : 5x = y
The Question is to find the value of y when x = 3
The Value of y at x = 3 can be found by simply substituting x = 3 in the equation we found.
⇒ y = 5x
⇒ y = 5 × 3
⇒ y = 15
So, the Value of y when x = 3 is 15
So basycilly slope intercept form is y=mx+b where m=slope and b=y intercept
slope=-1
subsiute
y=-1x+b
y=-x+b
so we are given the point (-3,2)
x=-3 and y=2 is one solution
subsitue and solve for b
2=-(-3)+b
2=3+b
subtract 3 from both sides
-1=b
the slopt inercetp form is y=-x-1
Answer:
6.3
Step-by-step explanation: Divide 7 by 10 and get .7 then you would multiply that by 9 and youll get 6.3
