Answer:

y-4=\frac{1}{5}(x-7)

Step-by-step explanation:

The point-slope form of a line is given by:

y-y_1=m(x-x_1)

Where

(x_1,y_1) is the coordinate pair (any of the points given)

m is the slope. The ratio of change in y coordinates by x coordinates

Let's calculate the slope:

m=\frac{4-3}{7-2}\\m=\frac{1}{5}

Now, it is given "y - 4", so y_1 is 4, so they are using the coordinate pair (7,4). So we can say x_1 = 7

Now we have all the values, lets write the equation:

y-y_1=m(x-x_1)\\y-4=\frac{1}{5}(x-7)

This is the point-slope form.

how many pounds of coffee worth $10 a pound should be added to 20 pounds of coffee worth $4 a pound to get a mixture worth $5 a
Solnce55 [7]

Answer:

4

Step-by-step explanation:

1. if the mass of coffee worth $10 is 'x', then its worth is 10x, and the worth of the mixture is 5(x+20);

2. using the previous item it is possible to write the next equation:

5(x+20)=4*20+10*x; ⇒ x=4.

3. the required mass is 4 pounds.

Refer to the figure below. If m<60 degrees l, find the measure of the other angles. Show your work(or explain) to receive ful
gladu [14]
All of the angles combined =360 degrees

Vertical angles are congruent, so if angle 1 = 60, so does angle 3

Logically we have to find the measure of angle 4 and angle 2 combined and divide by 2

60 + 60 = 120

360 - 120 = 240

240 / 2 = 120

angle 4 = 120
angle 2= 120

angle 3 = 60
