A crayon has a mass of 30 grams. How many crayons can be made with 30 kilograms of colored wax

1 answer:

5 0

The conversion factor between kilo and base unit which is grams in this question is 1000 so there is 1000 grams in 1 kilogram so first we need to convert kilograms to grams so we multiply by 1000 so 30kgx1000= 30000 grams so to find the number of crayons then we divide by 30 which is the mass of one crayon to find out how many we need so 30000/30= 1000 so you would need 1000 crayons

The graph of a linear system is shown

nirvana33 [79]

Answer:

The coordinates of the point of intersection is (2, 7)

Step-by-step explanation:

From the graph, we have the two intersecting straight lines each described as follows;

The first straight line graph from the left, we have;

y-intercept = (0, 5), x-intercept = (-5, 0) therefore, the slope, m = (0 - 5)/(-5 - 0) = 1

The equation of the graph is slope-intercept form is y - 5 = 1×(x - 0)

Which gives;

y = x + 5.........................(1)

The second lie graph has y-intercept = (0, 9), x-intercept = (9, 0) therefore, the slope, m = (0 - 9)/(9 - 0) = -1

The equation of the graph in slope-intercept form is y - 9 = -1×(x - 0)

Which gives;

y = -x + 9.......................(2)

To find the point of intersection, we equate equation (1) to equation (2), which are the y-value function of x, we have;

x + 5 = -x + 9

x + x = 9 - 5

2·x = 4

x = 4/2 = 2

x = 2

From either equation (1) or equation (2), we can find the value of y as follows;

y = -x + 9, where x = 2 gives;

y = -2 + 9 = 9 - 2 = 7

y = 7

The coordinates of the point of intersection is (2, 7).

What form of a linear equation is y - 6 = -4(x + 2) ?

Softa [21]

Answer:

Point slope form

Step-by-step explanation:

Given

$y - 6 = -4(x + 2)$

Required

Determine the form of linear equation

A linear has just three forms:

1. The slope intercept form.: This is always in form of $y = mx + b$

2. The point slope form: This is always in form of $y - y_1 = m(x - cx_1($

2. The standard form: This is always in form of $Ax + Bxx = c$

<em>By comparison, the three forms with the question, we can see that option B answers the question.</em>
