Answer:

Kayla wants to find the width, ab, of a river. she walks along the edge of the river 65 ft and marks point c. then she walks 25 ft further and marks point d. she turns 90° and walks until her location, point a, and point c are collinear. she marks point e at this location, as shown. (a) can kayla conclude that δ and δ are similar? why or why not? (b) suppose de = 15 ft. what can kayla conclude about the width of the river?

When you are given an equation or an expression and told the values for the variables, you can just substitute them into the equation to solve:

8b^2 - 5m + 12
8(6)^2 - 5(8) + 12
8(36) - 40 + 12
288 - 40 + 12
248 + 12

Find the y-intercept of the following function: <img src="https://tex.z-dn.net/?f=2x%20-%204y%20%3D%209" id="TexFormula1

fomenos

Hi there!

$\large\boxed{0, -\frac{9}{4} }$

2x - 4y = 9

Begin by isolating the y variable by moving 2x to the right-hand side of the equation. (Subtract 2x from both sides):

2x - 2x - 4y = 9 - 2x

-4y = 9 - 2x

Further isolate by dividing both sides by -4:

-4y / (-4) = (9 - 2x) / (-4)

y = -9/4 - 2x/(-4)

Simplify further:

y = -9/4 + 1/2x

y = 1/2x - 9/4

The "b" value is the y-intercept, therefore:

x = 0 at y = -9/4

Answer:

Total interest to be paid: $210

Total amount to be repaid: $3,710

Step-by-step explanation:

You can ignore the monthly payment for this problem.

For simple interest, the formula is I = PRT where I = interest earned, P = principal amount borrowed/deposited, R = rate as a decimal, and T = time in years.

I = (3,500)(0.06)(1)

I = 210

Then add that to the amount borrowed ($3,500) and you're done.

3,500 + 210 = $3,710

Please let me know if you have questions.
