Answer 1
since x can cancel out u are left with 3y=-3 which means y prolly equals 1

plug it in

2x+(1)=5 & 2(1)=2x-8

then u will find x which is 2

x=2, y=1

line a passes through the points (3,4) and (-1,2). line b passes through the points (-12,0) and (-6,-4). at what point do the lines intersect

Answers

Answer:

The point of intersection of the two lines is;

(-9,-2)

Step-by-step explanation:

What we have to here is to get the equation of both lines, solve simultaneously and get the intersection points

For the first line;

The general form is

y = mx + b

formula for the slope is;

m = (y2-y1)/(x2-x1)

The points (3,4) and (-1,2)

m = (2-4)/(-1-3) = -2/-4 = 1/2

So the equation is;

y = 1/2x + b

To get b, let us substitute coordinates of the first point;

4 = 1/2 * 3 + b

4 = 3/2 + b

b = 4 - 3/2

b = (8-3)/2 = 5/2

So the equation is;

y = 1/2x + 5/2

For the second line;

Slope;

m = (-4-0)/(-6+12) = -4/6 = -2/3

The equation is;

y = -2x/3 + b

Let us substitute the first

0 = -2/3(-12) + b

0 = 8 + b

b = -8

The equation is;

y = -2x/3 - 8

Now , we want to get the intersection point

To do this, we have to solve both equations simultaneously;

Since we have an expression for y in both cases, let us equate both y

-2x/3-8 = 1/2x + 5/2

Multiply through by 6

-4x - 48 = 3x + 15

-4x-3x = 15 + 48

-7x = 63

x = 63/-7

x = -9

To get x;

Recall;

y = -2x/3 - 8

y = -2/3(-9) - 8

y = 6 - 8

y = -2

I need help on this and the first person who answer correctly gets a BRANLIST​

Answers

Answer:

7 lbs. or option B.

Step-by-step explanation:

To figure out how much the chairs weigh to then divide them, you first need to subtract 36 from 92.

92 - 36 = 56

Now, we have to divide 56 by the number of chairs we have because we need to find out how much a single chair weighs.

56 ÷ 8 = 7

So, each chair weighs 7 lbs.

Answer:

B) 7 lbs

Step-by-step explanation:

To find how much the chairs weigh, you must subtract 36 from 92.

92 - 36 = 56

We have to divide 56 by 8 or the number of chairs.

56 ÷ 8 = 7

B) 7 lbs

A remote control airplane with an original price of $85 is on sale for $76.50. What is the percent of the discount?

Answers

Answer:

10% dicount

Step-by-step explanation:

76.50 / 85.00 = .9

The airplane cost 90% of its original value, meaning you have a 10% discount

10% of 85 =  .1 x 85 = 8.50

85.00 - 8.50 = 76.50

10% that is the answer

If m = 110°, then m =

70
80
110

Answers

Answer:

70

Step-by-step explanation:

Given

∠PDB = 110°

PDis the tangent to the circle whose centre is E

Construction

Join points D and E.

∠DPE= 90° [Since angle in a semi circle is 90°]

Also ∠PDE = 90° [Since radius ⊥ tangent]

From the figure we have,

∠PDB=∠PDE + ∠DBE

i.e. 110° = 90° + ∠DBE

Therefore, ∠DBE =20°

Now in ΔBED, BE = ED [Radii]

So, ∠EDB = ∠EBD =20°

In ΔBPD, we have

∠DPE = 90° & ∠DBE = 20°

Therefore, ∠DPB = 70°

Answer:

70 is the correct answer

Answers

the stick is 6 inches. if the stick is 6 and the string is 3 then the stick is double the string. if you multiply them both by ten because there is 10 each, you get 60 and 30. if you add them together you get 90 inches so the stick is 6 in. :))

Five friends want to travel on a trip. The bus ticket price is $50 for each friend, and the rooms and meals for everyone will cost $850.

To pay for the trip, friends work in the local shop. Each of them is paid $5 per hour. If each friend works the same number of hours, how many hours must each friend work so that there will be enough money to pay for the entire cost of the trip?

Answer this pls I'm this accounts cousin help me

Answers

Answer:

Step-by-step explanation:

Okay so first you need to find out how much money it will cost in total.

$50*5

=$250

$250+$850=

$1,100

Now, $1,100 divided by 5

1,100/5

=220 hours

And there are 5 friends so divide the total amount hours by 5.

220/5

=44 hours

So you see, each friend will need to work 44 hours.

I hope this helped :)

what does this equal y >4x - 5

Answers

Answer:

This represents the graph area above the line y = 4x - 5 shaded.

Step-by-step explanation:

y > 4x - 5 is an inequality.  First we graph y = 4x - 5, which has y-intercept (0, -5) and slope 4.  Next, we shade all of the area above this line (because the inequality y > 4x - 5 says that all y values are above 4x - 5).
