Answer:

x=40

Step-by-step explanation:

<h3> firstly 180 -110 = 70 (sumnof angle of a straight line ) </h3><h3>180 -110 = 70 (sumnof angle of a straight line ) also the triangle is an isocelels triangle of which the two sides have equal angle </h3><h3>180 -110 = 70 (sumnof angle of a straight line ) also the triangle is an isocelels triangle of which the two sides have equal angle there fore 70 +70 +x= 180 </h3><h3>180 -110 = 70 (sumnof angle of a straight line ) also the triangle is an isocelels triangle of which the two sides have equal angle there fore 70 +70 +x= 180 140+x=180 sum of angles of a triangle </h3><h3>180 -110 = 70 (sumnof angle of a straight line ) also the triangle is an isocelels triangle of which the two sides have equal angle there fore 70 +70 +x= 180 140+x=180 sum of angles of a triangle x=180 -140 = 40 </h3>

The scatter plot shows the profit by the month for a new company during its first year of operation. Which equation most closely

kondor19780726 [428]

The equation most closely models the line of best fit for the scatter plot is y = 2.5x

<h3>Equation of a line</h3>

A line is the distance between two points. The equation of a line in point-slope form is given as y =mx + b

m is the slope
b is the intercept

Using the coordinate points on the line (3, 5000) and (9, 20000)

Get the slope

Slope = 20000-5000/9-3
Slope = 15000/6 = 2500

Determine the y-intercept

5000 = 2500(3) + b

b = 5000 - 7500
b = -2500

Determine the equation

y = 2.5x - 2.5

Hence the equation most closely models the line of best fit for the scatter plot is y = 2.5x

Step-by-step explanation:

i'm assuming you copied the question wrong and that the right metals are, copper, nickel* and zinc.

here's an explanation~

copper ; 12 x 1/4 = 3 kg

nickel ; 5 x 1/4 = 1.25 kg

zinc ; 3 x 1/4 = 0.75 kg
