What is the function of the line?
Answer:
It is a linear function.
Step-by-step explanation:
The graph shows a straight line. Therefore the function must be linear. Unless you were asking about the equation of the line? Let me know.
To find the equation of this line, you would take the two points it passes through, (-3, 0) and (0, -2), and plug it into the slope formula, (y2-y1)/(x2-x1).
This would get you (-2 - 0)/ (0 - (-3)), which is -2/3.
Then, you can use slope intercept form to write the equation, since you have the y intercept already, (0, -2). Slope intercept is y=mx+b.
The line of the equation would then be y = -2/3x -2

solve for p
19/20=3p/18
Answer:
p=5.7
Step-by-step explanation:
Cross multiply.
Answer:
p = 5.7
Step-by-step explanation:
Given
[tex]\frac{19}{20}[/tex] = [tex]\frac{3p}{18}[/tex] ( cross- multiply )
60p = 19 × 18 = 342 ( divide both sides by 60 )
p = [tex]\frac{342}{60}[/tex] = [tex]\frac{57}{10}[/tex] = 5.7

Step-by-step explanation:
hi! to find f(-3) on this graph, go to the x-value -3 and find the y-value there. when we look at -3 on the x-axis, we go down and see that there is a point at (-3,-2). therefore, f(-3)=-2.

Answer:
54w-9
Step-by-step explanation:
the box to the right is -1 because you are multiplying 6w-1 by 9 (the box next to the blank one on the bottom). the other blank box below the 6w is going to be 54w since you multiply 6w and 9 to get that. therefore, 9(6w-1) is 54w-9.
x2y4(x2 - 16) - 9y4(x4 - 16)
simplify
Step-by-step explanation:
given the expression
[tex]x^22y^4(x^2 - 16) - 9y^4(x^4 - 16)[/tex]
we proceed by opening the brackets
[tex]x^2y^4(x^2 - 16) - 9y^4(x^4 - 16) \\\\x^4y^4-16x^2y^4-9x^4y^4+144y^4\\\\[/tex]
collet like terms we have
[tex]x^4y^4-16x^2y^4-9x^4y^4+144y^4 \\\\x^4y^4-9x^4y^4-16x^2y^4+144y^4 \\\\8x^4y^4-16x^2y^4+144y^4[/tex]
factoring we have
[tex]8x^4y^4-16x^2y^4+144y^4\\\\8y^4(x^4-2x^2)+144y^4[/tex]

Noah is buying a pair of jeans and using a coupon for 10%off. The total price is $56.70 which includes $2.70 in sales tax. Noah’s purchase can be modelled by the equation
x-0.1x+2.70=56.70
what does the solution to the equation mean in this situation?
How can you verify that 70 is not a solution but 60 is the solution?
Answer:
See below.
Step-by-step explanation:
So, we know that Noah's purchase can be modeled by the equation:
[tex]x-0.1x+2.70=56.70[/tex]
Part 1)
The solution to the equation will be the value of x.
In this case, x will represent the original price of the jeans.
We know that Noah has a coupon for 10% off the original price of the jeans.
So, 0.1x will represent how much of the original price Noah gets a a discount on.
Therefore, (x - 0.1x) represents the total cost of the jeans after the coupon.
So, x is our original price of the jeans.
Part 2)
To verify that 70 is not a solution, we can simply substitute 70 for x and check whether or not the equation is true. So:
[tex](70)-0.1(70)+2.7\stackrel{?}{=}56.70[/tex]
Multiply:
[tex]70-7+2.7\stackrel{?}{=}56.7[/tex]
Subtract:
[tex]63+2.7\stackrel{?}{=}56.7[/tex]
Add:
[tex]65.7\neq56.7[/tex]
However, we can verify that 60 is the solution by substituting. So, substitute 60 for every x:
[tex](60)-0.1(60)+2.7\stackrel{?}{=}5.7[/tex]
Multiply:
[tex]60-6+2.7\stackrel{?}{=}56.7[/tex]
Subtract:
[tex]54+2.7\stackrel{?}{=}56.7[/tex]
Add:
[tex]56.7\stackrel{\checkmark}{=}56.7[/tex]
So, 60 is indeed the solution and is the value of x.
So, this means that $60 was the original price of the jeans.
Answer:
$60

What are the solution(s) of x2-4-0?
X=-4 or X-4
X=-2 or X= 2
X=2
X=4
Answer:
X = - 2 or X = 2
Step-by-step explanation:
*completing the square*
X^2 - 4 = 0
X^2 = 4
X = +-√4
x = +-2
x= -2, 2
*factoring*
X^2 - 4 = 0
(x-2)(x+2) = 0
|. |
x = 2, x = -2
________________________________
(x-2)(x+2) = x(x+2) - 2(x+2) = x^2 + 2x - 2x - 4 = x^2-4
