If the coordinates of point E are (-4, y), what is the value of<br> у?

BlackZzzverrR [31]

Answer:

-8

Step-by-step explanation:

First we need to find the slope of CD.

We know C is (-10, -2)

and we know D is (10,6)

If we use the slope formula, we can see the slope is $m=\frac{6-(-2)}{10-(-10)}$

$m = \frac{8}{20} \\m=\frac{2}{5}$

We can see point F is at (6,-4)

We can find the equation of this line by using point slope form, and plugging in F as our point.

$y-(-4)=\frac{2}{5}(x-6)\\y=\frac{2}{5}x-\frac{32}{5}$

To find where E, we need to find the y value when x = -4

$y=\frac{2}{5}(-4)-\frac{32}{5}\\y =-8$

In the diagram below, value of x is: <br><br> A. 11 <br><br> B. 55<br><br> C. 5<br><br> D. 35

koban [17]

Sum of complementary angles = 90
so
5x + 35 = 90
5x = 90 -35
5x = 55
x = 11

answer is A.
x = 11

Lori buys a $586 certificate of deposit (CD) that earns 6.6% interest that compounds monthly. How much will the CD be worth in 1

Alex777 [14]

Answer:

Step-by-step explanation:

This problem can be solved using the compound interest formula

$A= P(1+r)^t$

Given data

A, final amount =?

P, principal = $586

rate, r= 6.6% = 0.066

Time, t= 13 years

Substituting our values into the expression we have

$A= 586(1+0.066)^1^3\\\ A= 586*(1.066)^13\\\ A= 586*2.295\\\ A= 1344.87$

To the nearest cent the in 13 years the CD will be worth $1344.9

a person walks 80 feet in 40 seconds. what equation represents this relationship. how many feet will the person walk in 10 secon

larisa [96]

Answer:

20 feet

Step-by-step explanation:

$\frac{80 feet}{40 seconds}$ = $\frac{x feet}{10 seconds}$

Simplify $\frac{80}{40}$

$\frac{80}{40}$ = $\frac{2}{1}$

Every 1 second, a person will walk 2 feet.

$\frac{x}{10}$ = $\frac{20}{10}$

X = 20 feet
