What is the y-intercept of the line connecting (1,5) and (4,14)?

1 answer:

7 0

The answer is C. b=2.
I found the answer by first finding the slope. To find the slope i found the difference of the y values and divided that by the difference of the x values.
14-5/4-1
This simplifies down to:
9/3 which equals 3.
I then plugged this into the slope intercept form: y=mx+b to get y=3x+b
The next step would be to plug in the values of one of the points to solve for b. The point I choose was (1,5). By plugging this point into the equation i got 5=3(1)+b which simplifies to 5=3+b which means that b=2

Can you solve number 7, number 8, and number 9

Hello!

To solve each expression, you need to substitute the given value for each given variable. If there is an x in the expression, then you substitute 5.07. If there's a y, then you substitute 1.5, and if there's a z, then you substitute 0.403.

7. 3.2x + y (substitute x = 5.07 and y = 1.5)

3.2(5.07) + (1.5)

16.224 + 1.5

17.724

8. yz + x (substitute y = 1.5, z = 0.403, and x = 5.07)

(1.5)(0.403) + (5.07)

0.6045 + 5.07

5.6745

9. z × 7.06 - y (substitute z = 0.403 and y = 1.5)

(0.403) × 7.06 - (1.5)

2.84519 - 1.5

1.34518

Final answers:

Number 7: 17.724
Number 8: 5.6745
Number 9: 1.34518

Answer:

$\%Tip = 13.04\%$

Step-by-step explanation:

Given

$Tip= \$31.29$

$Bill = \$208.60$

Required

Determine the percentage of the tip

First, we calculate the amount paid

$Amount = Tip + Bill$

$Amount = \$31.29 + \$208.60$

$Amount = \$239.89$

The percentage of the tip is then calculated using:

$\%Tip = \frac{Tip}{Amount} * 100\%$

$\%Tip = \frac{31.29}{239.89} * 100\%$

$\%Tip = \frac{31.29* 100}{239.89} \%$

$\%Tip = \frac{3129}{239.89} \%$

$\%Tip = 13.04\%$

max2010maxim [7]

Answer:

$5.40

Step-by-step explanation:

First, figure out the cost of the items with tax; for Tommy we have 20*0.08 = 1.6, add that 1.6 to the 20 and his purchase is $21.6, for John we have 25*0.08 = 2, add 2 to his 25 and his purchase is $27. To find the difference we subtract 27-21.6 = 5.4 or $5.40
