Simplifying
1.5d + 3.25 = 1 + 2.25d

Reorder the terms:
3.25 + 1.5d = 1 + 2.25d

Solving
3.25 + 1.5d = 1 + 2.25d

Solving for variable 'd'.

Move all terms containing d to the left, all other terms to the right.

Add '-2.25d' to each side of the equation.
3.25 + 1.5d + -2.25d = 1 + 2.25d + -2.25d

Combine like terms: 1.5d + -2.25d = -0.75d
3.25 + -0.75d = 1 + 2.25d + -2.25d

Combine like terms: 2.25d + -2.25d = 0.00
3.25 + -0.75d = 1 + 0.00
3.25 + -0.75d = 1

Add '-3.25' to each side of the equation.
3.25 + -3.25 + -0.75d = 1 + -3.25

Combine like terms: 3.25 + -3.25 = 0.00
0.00 + -0.75d = 1 + -3.25
-0.75d = 1 + -3.25

Combine like terms: 1 + -3.25 = -2.25
-0.75d = -2.25

Divide each side by '-0.75'.
d = 3

Simplifying
d = 3

First off you need to get all letters on on the left side of the equal sign, you will do this by subtracting 2.25 from the right and that would give you -0.75d+3.25=1 now you will subtract 3.25 from the right side and get -.75d=-2.25. And lastly you divide both sides by -0.75 and that will give you d= 3

A line which passes through at least two points of a curve
UNO [17]

Answer:

A line which passes through at least two points of a curve is called secant line.

Step-by-step explanation:

Consider the provided statement.

A secant, is a line that passes through two curve points.

It connects two points in the Cartesian plane on a curve where the curve can be describe by a function.

A secant line commonly refers to a line that intersects a circle at exactly two points.

Remember: The secant line is almost the same as a tangent line when two points are closed together.

Hence, A line which passes through at least two points of a curve is called secant line.

I need help what would be the equation for #10?
Nady [450]
Ok, so per month+comission+reimgurssement=total
we jsut want the comission

so total-permonth-reimbursement=comission=256.65-240-8.95=7.7

she made 7.7 comission

$7.70 is 5% of her salse
find 100%
remember that x%=x/100
hmm
7.7 is 5% of total sales
7.7=5/100 of total sales
tiems both sides by 100/5
770/5=total sales
154=total sales


her total sales was $154

ok, you want an equation?

256.65=240+0.05s+8.95 where s is her total sales

G(a)=a-5 <br> h(a)=2a-4 <br> find g(h(1))
suter [353]

Calculate h(1):

h(a) = 2a - 4 → h(1) = 2(1) - 4 = 2 - 4 = -2

Next calculate g(-2):

g(a) = a - 5 → g(-2) = -2 - 5 = -7

<h3>Answer: g(h(1)) = -7</h3>

For the blue picture, use Pythagorean theorem. So 8.7^2 + x^2 = 32^2. Now solve for x and that’ll give you the missing side
