Answer:
Step-by-step explanation:
6)Let the number be x
Product of a number and -4 = x * -4 = -4x
Product of a number and -4 increase by 3 : -4x + 3
-4x +3 = 9
Subtract 3 from both sides
-4x + 3 - 3 = 9 - 3
-4x = 6
Divide both sides by (-4)
-4x/-4 = 6/-4
x = -3/2
x = -1 1/2
7)Let the number be x
Add 9 to both sides
Multiply both sides with 6
x = 120
Answer:
Piyush walks faster than Laura
Step-by-step explanation:
we know that
The rate or speed is equal to the slope of the linear equation
<em>Laura</em>
y=3.5x
The slope is
<em>Piyush</em>
Determine the slope of the line
we have the points
(0,0) and (4,18)
The line represent a direct variation (because passes through the origin)
so
For x=4 h, y=18 mi
substitute
Compare the slopes
therefore
Piyush walks faster than Laura
All the points The point (-3.2), The point (-7.5), Point (2.-5), and The point (-14,6) is located in the solution region.
<h3>What is a graph?</h3>A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.
When we plot all the points on the graph we can see that all the points The point (-3.2), The point (-7.5), Point (2.-5), and The point (-14,6) are located in the solution region.
Therefore all the points The point (-3.2), The point (-7.5), Point (2.-5), and The point (-14,6) is located in the solution region.
