Given
Grant and Pedro are comparing their stocks for the week
On Monday, their results were opposite.
for Monday if Grant lost $4
Explain how you would graph their results for Monday.
To proof
let us assume that value of stocks after a week = x
As given in question
for Monday if Grant lost $4
i.e x= - $4
result were opposite for grant and pedro.
thus
for Monday if Pedro gain $4
i.e x = $4
Therefore two values are
x = -4 and x = 4 is shown in graph given below.
This shows that x = -4 lies left of 0 to x-axis and x = 4 lies right of 0 to x- axis.
Answer:
(4,-3)
Step-by-step explanation:
Easiest way to do this without any advanced methods is to use the answer choices to your advantage.
For a.) we have (1,1) meaning x = 1 and y = 1 if we get a 7 for the first equation and a -2 for the second equation then that is the correct answer.
Let x=1, y =1:
4(1)+3(1)=4+3=7 Correct so far.
1+2(1)=1+2=3 Incorrect since we should have got a -2 if this was the solution
Let (0,-1) x = 0, y = -1:
4(0) + 3(-1) = 0 -3 = - 3 Incorrect so we can stop there next answer choice.
Let (4,-3) x = 4 y = -3:
4(4)+3(-3)=16-9=7 Correct so far.
4+2(-3)=4-6=-2 Both are correct!
Therefore the solution (where the lines intersect) is (4,-3).
Answer:
12√2
Step-by-step explanation:
Use the Pythagorean Theorem here:
(12 cm)^2 + (12 cm)^2 = 288 cm^2.
The length of the hypotenuse is √288 = (√4)(√72) = 2(√36)(√2) = 12√2
