we can do this by 2 ways
1- by plotting the points on graph and then tracing the points to get shape,
for linear, we will get straight line
for quadratic, we will get parabola
in this case, it is linear as we get a straight line
2- by solving for values of x and y
consider standard linear equation y = mx +c where m is slope and c is constant
by putting given values of x and y we get
y + 2x = 4(answer)
if we consider standard parabola equation
y^2 = 4ax
this equation is not true for given points
Answer: 7.2$
hope it helps :)
step-by-step explanation:
Cost of each box = 3$
Cost of 3 boxes without 20% coupon = 9$
With 20% off Coupon = 9 by 100 multiplied by 20
(the zero's cut with each other leaving)
= 9 by 10 multiplied by 2
(9 multiplied by 2 = 18)
= 18 by 10
(18 divided by 10 = 1.8)
= the 20% of 9$ is equal to 1.8
when subtracted with the total cost leaves 7.2$
Step-by-step explanation:
Y varies directly as cube root of x is written as
y = k³√x
where k is the constant of proportionality
<h2>A).</h2>
when y = 3
x = 27
We have
![3 = k \sqrt[3]{27}](https://tex.z-dn.net/?f=3%20%3D%20k%20%5Csqrt%5B3%5D%7B27%7D%20)
But ³√27 = 3
That's
3 = 3k
Divide both sides by 3
k = 1
<h3>The value of the constant is 1</h3>
<h2>B).</h2>
The value of the relationship is
<h2>
![y = \sqrt[3]{x}](https://tex.z-dn.net/?f=y%20%3D%20%20%5Csqrt%5B3%5D%7Bx%7D%20)
</h2>
<h2>C).</h2>
When x = 8
We have
<h2>
![y = \sqrt[3]{8}](https://tex.z-dn.net/?f=y%20%3D%20%20%5Csqrt%5B3%5D%7B8%7D%20)
</h2>
<h3>y = 2</h3>

Answer:
1.5
Step-by-step explanation:
An equation 10(23+7)=100ℓ+100ℓ is given and we are asked to find the value of ℓ.
To solve the equation, we have to move all the values containing ℓ on one side and other values on other side of equality.
10(23+7)=100ℓ+100ℓ
Multiply 10 with 23 and 7 which gives
(10 * 23 ) + ( 10 * 7) = 200 ℓ
Solving the above equation,
230 + 70 = 200 ℓ
300 = 200 ℓ
=> ℓ = 300 / 200
=> ℓ = 3/2
=> ℓ = 1.5
