(Hope this helps can I pls have brainlist (crown)☺️)
Step-by-step explanation:
For how to graph this, best to look at the guidelines for graphing a break-even formula.
What we do want to know is where these two values equal each other.
So, set: 400 + 0.20X = 800 + 0.10X
Subtract 400 from both sides; also subtract 0.10X from both sides, to get:
0.10X = 400
To solve for "X", divide out both sides by: 0.10, to get:
X = 4,000
What can can glean from this, is that:
(1) The sales person is better off accepting the higher base salary, up to the point of sales being no more than $4,000;
(2) The sales person is better off accepting the lower base salary, if their sales are normally expected to exceed $4,000.

What does x equal
Answers
+ 15 +15
3x = 54 (divide by 3 on each side)
X = 18
Answer:
X=18
Step-by-step explanation:
To isolate X you need to get rid of the -15 to do that you can add 15 on both sides of the equation resulting in 3x=54 now you need to divide both sides by 3 to get x on its own which is X=18.

Answers
Answer:
steps below
Step-by-step explanation:
From the graph: parabola pass (0,4) (3,4) (1,2)
equation: y = ax² + bx + c
(0,4): c = 4
(3,4): 9a + 3b + 4 = 4 9a+3b = 0 3a + b = 0 ... (1)
(1,2): a + b + 4 = 2 a+b = -2 ... (2)
(1)-(2): 2a = 2 a = 1
(2): b = -3
parabola equation: f(x) = x² - 3x +4
(a) f(3) = 3² - 3*3 + 4 = 4
(b) normal line: parallel to tangent line y = 3x -5 at (3,4)
slope of line N: -1/3 pass (3,4)

Students deliver newspapers and magazines to houses.
One day, they have to deliver 850 newspapers and 1440 magazines.
Each student can deliver either 25 newspapers or 60 magazines in 1 hour.
Each student can only work for 6 hours.
Work out the minimum number of students needed.
Answers
Answer:
4 students to deliver magazines and 6 students to deliver newspaper
Step-by-step explanation:
magazine [tex] = 60 \times6 = 360 \\ 850 \div 360 = 4[/tex]newspaper [tex] = 25 \times 6 = 150 \\ 850 \div 150 = 5.6[/tex]The minimum number of students needed is 6.
Given that, in one day students can deliver 850 newspapers and 1440 magazines. Each student can deliver either 25 newspapers or 60 magazines in 1 hour.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Now, in 1 hour a student can deliver 25 newspapers, so in 6 hours a student can deliver 25 × 6 =150
So, number of students = 850/150 = 5.66
≈ 6
Now, 60 × 6 =360
So, number of students = 1440/360 = 4
Therefore, the minimum number of students needed is 6.

If x = a sin α, cos β, y = b sin α.sin β and z = c cos α then (x²/a²) + (y²/b²) + (z²/c²) = ?

[tex]\large\underline{\sf{Solution-}}[/tex]
Given:
[tex] \rm \longmapsto x = a \sin \alpha \cos \beta [/tex]
[tex] \rm \longmapsto y = b \sin \alpha \sin \beta [/tex]
[tex] \rm \longmapsto z = c\cos \alpha[/tex]
Therefore:
[tex] \rm \longmapsto \dfrac{x}{a} = \sin \alpha \cos \beta [/tex]
[tex] \rm \longmapsto \dfrac{y}{b} = \sin \alpha \sin \beta [/tex]
[tex] \rm \longmapsto \dfrac{z}{c} = \cos \alpha[/tex]
Now:
[tex] \rm = \dfrac{ {x}^{2} }{ {a}^{2}} + \dfrac{ {y}^{2} }{ {b}^{2} } + \dfrac{ {z}^{2} }{ {c}^{2} } [/tex]
[tex] \rm = { \sin}^{2} \alpha \cos^{2} \beta + { \sin}^{2} \alpha \sin^{2} \beta + { \cos}^{2} \alpha [/tex]
[tex] \rm = { \sin}^{2} \alpha (\cos^{2} \beta + \sin^{2} \beta )+ { \cos}^{2} \alpha [/tex]
[tex] \rm = { \sin}^{2} \alpha \cdot1+ { \cos}^{2} \alpha [/tex]
[tex] \rm = { \sin}^{2} \alpha + { \cos}^{2} \alpha [/tex]
[tex] \rm = 1[/tex]
Therefore:

x=19
To find y, input the value of x into the equation 4x-11 since this equation is equal to 2y+19
4(19)-11 = 65
