Answer: (EF) ax+by+c=0

do you know normal vector? vector EF=(7;3) --> normal vector (-3;7)

---> (EF)-3x+7y+c=0. because (EF) passes through E(1;-3) so -3.1+7.(-3)+c=0 ---> c=24

(EF) -3x+7y+24=0

Answer:

Step-by-step explanation:

Let's start with an equation:

y=k*x+b

k=(-3-0)/(1-8)=3/7

Now I'm going to plug in E:

-3=3/7*1+b

so b=-24/7

so the equation is:

y=3/7*x-24/7

Let's multiply each term in this equation by seven.

The standard form is:

3x-7y=24

Find the equation in slope-intercept form that describes a line through (2, 4) with slope 0
True [87]

Since we already know that the slope is 0, x cancels out in the equation.

y = mx + b → y = b

We just need to find the y-intercept. Using the coordinate (2, 4) we can substitute with y.

4 = b

Hence, the answer is b) y = 4

Hope This Helped! Good Luck!

54 thousands 6 hundreds 12 tens – 15 thousands 8 hundreds 26 tens = ________(1 Point)
Afina-wow [57]

Answer:

38,660

Step-by-step explanation:

54 thousands 6 hundreds 12 tens – 15 thousands 8 hundreds 26 tens

54 thousands = 54000

6 hundreds = 600

12 ten = 12*10 = 120

54 thousands 6 hundreds 12 tens = 54000+600+120 = 54720

15 thousands = 15000

8 hundreds = 800

26 tens = 26*10 = 260

15 thousands 8 hundreds 26 tens = 15000+800+260 = 16060

Thus,

54 thousands 6 hundreds 12 tens – 15 thousands 8 hundreds 26 tens

= 54720- 16060 = 38,660 (Answer)
