ANTONII [103]2 years ago
3 0

Answer:

y=75x+25

Step-by-step explanation:

We know that rowan opens the savings account with $25, so the y-intercept (or b) is 25 as this is what he starts with at 0 months. For each additional month, he saves $75, so we can set the slope to $75 and let x be the number of months. This linear equation will find the balance in Rowan's savings account

9. Determine whether (-3,2) is a solution of<br> Y = 2x +8<br> Y= -X+1
miss Akunina [59]
2 = 2(-3) + 8
2 = -6 + 8
2 = 2

true.

2 = 3 + 1
2 = 4

false.

this is not a solution because both equations have to be true.

in chemical formulas, there are often subscript numbers (such as the 2 in h2o, or the 6, 12, and 6 in c6h12o6). what do these su
Gnesinka [82]

In a Chemical formula,  Subscript figures tell us how numerous of the element to their upper-left there are in the patch.

What is a chemical formula?

  • In chemistry, a chemical formula is a way of presenting information about the chemical proportions of titles that constitute a particular chemical emulsion or patch, using chemical element symbols, figures, and occasionally also other symbols, similar as hiatuses, dashes, classes, commas, and plus() and disadvantage( −) signs.
  • These are limited to a single typographic line of symbols, which may include subscripts and subtitles.
  • A chemical formula may indicate certain simple chemical structures, it isn't the same as a full chemical structural formula.

The subscript number indicates the total number of titles of an element present in a patch.

While witting a chemical formula, first we've to write the symbol of an element and also write the number at the bottom of the symbol.

For illustration,

C_6H_{12}O_6 is the chemical formula of the glucose patch. The glucose patch is made up of six carbon titles, twelve hydrogen titles, and 6 oxygen titles.

The number 6 of the carbon snippet is written after and at the bottom ( lower- right) of the symbol of carbon element (C). also, the number 12 is written lower-right of the symbol of hydrogen element (H), and the number 6 is written lower-right of the symbol of oxygen element( O).

thus, the subscript figures tell us how numerous of the element to their upper-left there are in the patch.

If f(x) and r1(x) are inverse functions of each other and f(x)=2x+5 , what is f^-1(8) ?
GenaCL600 [577]

Answer:

3/2

Step-by-step explanation:

Given y = 2x + 5, let's rewrite the equation in terms of x;

y = 2x + 5 => Bring 5 to the other side

2x = y - 5 => Divide either side by 2

x = (y - 5)/2

If we want to take the inverse, simply swap the variable's positions...

We have y = (x - 5)/2

Now let's determine f^-1(8), substituting for "y" provided y is our inverse, f^-1

f^-1(8) = (8 - 5)/2 = 3/2

Solution: 3/2
