PLEASE HELP!!!!!! PLEASE WILL MARK BRAIN FOR FIRST AND RIGHT ANSWER!!!
Answers
Answer:
yes
Step-by-step explanation:
Answer:
No
Step-by-step explanation:
All you need to do is solve for x and y because the intersection of both lines will only have one intersection.
since both equations are equal to y then you can set them equal to each other:
7x+8=x+1
6x=-7
x=-7/6
then inset back into y=x+1
y=-7/6+1
y=1/6
so that is the only point of intersection of the lines and it cannot be (3,8)

proportions in triangles. solve for x
Answers
x / 3 = x + 4 / x + 2
Cross multiply
x * x + 2 = 3 * x + 4
Distribute
x^2 + 2x = 3x + 12
Set equal to zero
x^2 - x - 12 = 0
Factor
(x - 4)(x +3) = 0
Solve
x = 4 or x = -3
Length can’t be negative so x = 4
Check:
x / 3 = x + 4 / x + 2
4 / 3 = 4 + 4 / 4 + 2
4 / 3 = 8 / 6
4 / 3 = 4 / 3 :)

The mass of Parcel A was 0.7 kg. Parcel B was heavier than Parcel A.
Parcel C had the same mass as Parcel B. The total mass of the three
parcels was 2.5 kg. What was the mass of Parcel C?
Answers
Answer: 0.9kg
Step-by-step explanation:
Since we are informed that Parcel C had the same mass as Parcel B, let their mass be represented by x.
Therefore,
Parcel A + Parcel B + Parcel C = 2.5
0.7 + x + x = 2.5
0.7 + 2x = 2.5
2x = 2.5 - 0.7
2x = 1.8
x = 1.8/2
x = 0.9
The mass of parcel C is 0.9kg

Amelia runs a catering business. Based on her records, her weekly profit can be modeled by P=-2x^2+152x-150P=−2x 2 +152x−150, where xx is the number of meals she caters and PP is her profit.
Answers
Answer:
The least number of meals Amelia needs to cater in order to begin making profit = 38 meals.
Step-by-step explanation:
Given - Amelia runs a catering business. Based on her records, her weekly
profit can be modeled by P= -2x² + 152x - 150, where x is the
number of meals she caters and P is her profit. When P is negative,
Amelia losses money.
To find - What is the least number of meals Amelia needs to cater in order
to begin making profit.
Proof -
As given, P = -2x² + 152x - 150
Now,
Above the break-even point, she only get profit
The break -even point is a point where there is no profit, and no loss.
Now,
For break-even point,
[tex]\frac{dP}{dx} = 0[/tex]
⇒[tex]\frac{d}{dx}( -2x^{2} + 152x - 150) = 0[/tex]
⇒-4x + 152 = 0
⇒- 4x = - 152
⇒4x = 152
⇒x = [tex]\frac{152}{4}[/tex] = 38
∴ we get
If Amelia caters at least 38 meals , then she makes Profit.
