Answer: Option D) 3 x 5 + 4 x 2
Step-by-step explanation:
- Since a dozen muffins costs $5.
Buying 3 dozen muffins means (3 x $5)
- Since Large bottles of juice cost $2.
The cost of 4 large bottles of juice is (4 x $2)
Hence, the total cost is (3 x $5) + (4 x $2)
= $15 + $8
= $23
Now, you'll notice that "3 x 5 + 4 x 2" gives 23.
Thus, it is the only expression that could be used to find the total cost.
$20090
because, in three years it would have depreciated by 18% (9%*3=18) so you would subtract 18% off of $24500
Answer/Step-by-step explanation:
✔️Slope (m) using the two points (2, 4.58) and (5, 4.28):

Slope (m) = -0.1
✔️Initial Value = y-intercept = b
To find b, substitute x = 2, y = 4.58, and m = -0.1 into y = mx + b.
(Note: y is P(t) and x is t).
Thus:
4.58 = (-0.1)(2) + b
4.58 = -0.2 + b
Add 0.2 to both sides
4.58 + 0.2 = b
4.78 = b
b = 4.78
Initial value = 4.78
✔️Equation for the linear function:
Substitute b = 4.78, and m = -0.1 into P(t) = mt + b
Thus the equation would be:
P(t) = -0.1t + 4.78
✔️The y-intercept = initial value = 4.78
✔️The x-intercept = the value of t when P(t) = 0.
To get this, substitute P(t) = 0 into P(t) = -0.1t + 4.78.
Thus:
0 = -0.1t + 4.78
Add 0.1t to each side
0.1t = 4.78
Divide both sides by 0.1
t = 47.8
x-intercept = 47.8
Answer:
length = 18 mt
Width = 10 mt
Step-by-step explanation:
Let the length of the field be x
width of the field be y
Hence
P=2(x+y)
P=56 (given)
56=2(x+y)
Dividing both sides by 2 we get
x+y=28 ---(A)
Also given that width of the parallelogram is 8 meters less than its length
Hence
y=x-8
or x-y=8 ---(B)
Adding A and B
2x=36
x=18
y=x-8
y=18-8=10
Hence length = 18 mt
Width = 10 mt
Answer:
y=32
Step-by-step explanation:
y=3(8)+8
y=24+8
24+8=32
y=32
