5w=30
5w/5=30/5
w=6
Therefore w is equal to 6
1) question 18 of 20
-7x/5-(4y)=7
4y=-7x/5-(7)
y=-7x/20-(7/4).
if x=0 ⇒y=-7*0/20-7/4=-7/4 ⇒y-intercept is-7/4
fi y=0 ⇒ -7x/20-(7/4)=0
-7x/20=7/4
x=(7*20) / [4*-(7)]=-5 ⇒x-intercept is -5
Solution: D) x-intercept is -5 ; y-intercept is -7/4
Question 19 of 20
P₁=(x₁,y₁)
P₂=(x₂,y₂)
m=slope
m=(y₂-y₁) / (x₂-x₁)
Then:
A(1,7)
B(10,1)
m=(1-7) / (10-1)=-6/9=-2/3.
Solution: B)-2/3
Question 20 of 20:
y-y₀=m.(x-x₀)
A(4,3)
B(-4,-2)
m=(-2-3) / (-4-4)=-5/-8=5/8
y-3=(5/8).(x-4)
y=5x/8-(20/8)+3
y=5x/8-(20/8)+24/8
y=5x/8+(4/8)
y=5x/8+1/2
solution: B) y=5x/8+1/2
This is the Communative property of multiplication
Answer:
$ 75,673.89
Step-by-step explanation:
The formula for compounded interest is:

here A = total value in future
P= principal amount
r= annual interest rate
n= number of times interest is compounded
t= time (in years) the interest is compounded for
Plugging in values from the question we get:
250,000 = P * (1 + 0.1/12)^(12*12)
Solving for the principal amount (P) we get $ 75,673.89
