Jim went to the store and bought 2 pencils, 4 erasers, a binder, and 3 packs of paper for school. He paid $1.50 for each pencil, $0.75 for each erasers, $5 for each binder, and $4 for every pack of paper. If he paid with a $50 bill, how much change did he get?

The gradient of the blue line given in the graph is 4 and this can be determined by using the slope intercept form and point slope form of the line.

Given :

The graph of the line is given.

The following steps can be used to determine the equation of a line given in the graph:

Step 1 - First determine the points through which the line passes through that is:

Points - (4,0) and (6,8)

Step 2 - Use the point-slope form of the line which is given by the equation:

[tex]\dfrac{y-y_1}{x-x_1}=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

where [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are the point on the line.

Step 3 - Substitute the value of the points in the above equation.

[tex]\dfrac{y-0}{x-4}=\dfrac{8-0}{6-4}[/tex]

Cross multiply in the above equation.

2y = 8(x - 4)

y = 4x - 16

Step 4 - Now, compare the above equation with slope-intercept form.

m = 4

Answer:

Cost of medium iced caramel latte = $3.59

Step-by-step explanation:

Assume;

Cost of medium iced caramel latte = x

Cost of blueberry muffin = y

So,

On Thursday

x + y = 5.18......eq1

On Friday

2x + 3y = 11.95.....eq2

Eq1 × 3

3x + 3y = 15.54......eq3

eq3 - eq2

x = 3.59

Cost of medium iced caramel latte = $3.59

Answer:

Hi...

2x+4+2x-9+x=180

5x-5=180

5x=185

X=185/5=37....so

A=2*37-9=65

B=2*37-4=70

Answer: see explanation

Step-by-step explanation:

Sum of all angles in a triangle is 180

So add all those angles together equals 180.

2x + 4 + 2x -9 + x = 180

Combine like terms.

5x -5 = 180

5x = 185

X = 37

Now plug x in for the angles

A = 2x -9

A = 2(37) - 9

A= 74 - 9 = 65

B = 2x + 4

B = 2(37) + 4

B = 74 + 4

B = 78

Answer:

Meghan cannot claim any amount as a medical deduction.

Step-by-step explanation:

Given that:

Amount paid by Meghan for insurance = $9212

Meghan's medical expenses = $5700

Her medical insurance covers 80% of these expenses

Meghan's adjusted gross income = $65,432

Her medical expenses that are not covered under medical insurance is:

[tex]= 5700 \times (1- \dfrac{80}{100})[/tex]

[tex]= 5700 \times (0.2)[/tex]

= $1140

Similarly, 7.5% of her gross income is;

= 65,432 × (7.5/100)

=$4907.4

Since $1140 < $4907.4

The amount of $1140 does not  exceed $4907.4

Thus, Meghan cannot claim any amount as a medical deduction.
