Answer:
Step-by-step explanation:
Given that:
Let x represent the number of pumpkins that can be purchased for $25
The cost of a particular pumpkin to decorate a porch = $3.50
The amount to be spent on pumpkins by Jay is x < $25
Thus,
With such an amount;
Jay would be able to buy $25/$3.50 = 7 pumpkins
3a(4a²-5a+12)
12a³-15a²+36a

u need to provide some information! GjG
like side length or height
Let's start by solving the first equation.
a) -3 = 7 + 2t/3
To begin simplifying this equation, we should multiply both sides by 3 to get rid of the denominator on the right side of the equation.
-9 = 7 + 2t
Next, we should subtract 7 from both sides to cancel out the 7 on the right side.
-16 = 2t
Finally, we should divide both sides by 2.
t= -8
Now let's move on to the next equation.
b) 4(5x-2) = 7(2x+3)
Let's use the distributive property to get rid of the parentheses and their coefficients.
20x-8 = 14x + 21
Now, lets subtract 14x from both sides of the equation.
6x - 8 = 21
Next, let's add 8 to both sides of the equation.
6x = 29
And divide both sides by the coefficient of x, which is 6.
x = 29/6 or 4 5/6
Now for the last equation.
C) 2x - 6 = 20 - 2.5x
First, we should add 2.5x to both sides to cancel out the -2.5x on the right side of the equation.
4.5x - 6 = 20
Now, let's add 6 to both sides to get the variable term alone.
4.5x = 26
Finally, we should divide both sides by 4.5 to get x by itself.
x = 5 7/9

Answer:
The equation of this line is y = -3x + 7
Step-by-step explanation:
Remember that when writing an equation for a graphed linear line, we must write it in slope intercept form (y=mx+b). The m represents the slope, and the b represents the y-intercept.
<em>(</em><em>The slope determines the direction in which the line </em><em>goes</em><em>,</em><em> </em><em>and</em><em> </em><em>is</em><em> </em><em>written</em><em> </em><em>as</em><em> </em><em>rise</em><em>/</em><em>run</em><em>.</em><em>)</em>
In this case the slope is going to be negative, since the line is going downwards to the right. Additionally the slope of this line is -3/1 or just -3.
<em>(</em><em>The</em><em> </em><em>y</em><em>-</em><em>intercept</em><em> </em><em>is</em><em> </em><em>the</em><em> </em><em>point</em><em> </em><em>in</em><em> </em><em>which</em><em> </em><em>the</em><em> </em><em>line</em><em> </em><em>crosses</em><em> </em><em>the</em><em> </em><em>y</em><em>-</em><em>axis.</em><em>)</em>
In this case, since the line crosses the y-axis at positive 7, the y-intercept will be 7.
So all together we have y = -3x + 7.
Hope this helps you :)
