Number line , if the points match up with the real number system it’ll be number line, it wouldn’t be a fraction, because a fraction is part of a number, it wouldn’t be a numerator because the numerator is part of a fraction, it would not be reciprocal

Ms. Stone decided to purchase 2 reusable bottles instead. When she got to the counter, she realized she had $10.15, only ⅝ of th
Bumek [7]

Answer:

The price of one reusable bottle is $8.12

Step-by-steetp explanation:

Ms stone wanted to purchase two reusable bottles but discovered she had only ⅝of the Mone and that ⅝ is equal to $ 10.15.

So the cost of what she wants to purchase will be called x.

Mathematically

⅝ * x = 10.15

X = (10.15*8)/5

X = 81.2/5

X= 16.24

The price of the two bottles is $16.24

So the price if one bottle will be calculated as follows.

2 bottles=$ 16.24

One bottle= $16.24/2

One bottle= $8.12

The price of one reusable bottle is $8.12

Creat an equation for a cubic function, in standard form, that has x- intercept given by the set {-3,1,7} and which passes throu
prohojiy [21]

Given :

Set of x-intercepts {-3,1,7},

point through which it passes (-2,54)

Now,

Step 1: Substitute value of x intercepts in equation, y=a(x-p)(x-q)(x-r), we get,

y=a(x-(-3))(x-1)(x-7)

y= a(x+3)(x-1)(x-7)               ... equation (1)

Step 2: substitute x an y with the point through which it passes,

54=a((-2)+3)((-2)-1)((-2)-7)

54 = 27a

∴ a=2

Step 3: Now, substituting value of a in equation (1), we have

y=(2x+6)(x^{2} -8x+7)

y=2x^{3}-10x^{2}  -34x +42   (Requited cubic equation)

Write an equation of the line that passes through point p and is perpendicular to the line with the given equation
goldenfox [79]
Do you have the specific point??

Remember, if 2 lines are perpendicular, their slopes are opposite reciprocals. So if one line has a slope of 4, the other line should have a slope of -1/4.

Hopefully your equation is in y=mx+b form. If so,

make sure you know slope (m) and the y-intercept. After this is done, plug in the points from p for y and x, and make sure to turn m into -1/m. Solve for b, and your new equation should be y=(new slope)x+(new y-intercept)
