Answer:
Washer $735
Dryer $245
Step-by-step explanation:
If x is the cost of the washer, and y is the cost of the dryer, then:
x + y = 980
x = 3y
Solve with substitution.
3y + y = 980
4y = 980
y = 245
x = 735
Given:
The inequality is
To find:
The value of x and then graph on the number line.
Solution:
We have,
Subtracting 19 from both sides, we get
It means all the real values of x which are less than or equal to 4 are in the solution set. So, an arrow approaches towards left from x=4 as shown in the below figure.
Answer:
let t be tickets and b be beverages
Step-by-step explanation:
16t + 3b = 1900
1 Subtract <span>11</span> from both sides
<span>y-1={3}^{x}<span>y−1=<span>3<span><span>x</span><span></span></span></span></span></span>
2 Use Definition of Common Logarithm: <span>{b}^{a}=x<span><span>b<span><span>a</span><span></span></span></span>=x</span></span> if and only if <span>log_b(x)=a<span>lo<span>g<span><span>b</span><span></span></span></span>(x)=a</span></span>
<span>\log_{3}{(y-1)}=x<span><span><span>log</span><span><span>3</span><span></span></span></span><span>(y−1)</span>=x</span></span>
3 Switch sides
<span><span>x=\log_{3}{(y-1)}<span>x=<span><span>log</span><span><span>3</span><span></span></span></span><span>(y−1)
