solve the following y=x-5 and y=5x-13

a) (-4,5)
b) (-3,2)
c) (2,-3)
d) (2,3)

Answer: 17/21

Step-by-step explanation:

Number of cities = 42

Fraction of cities that has lake = 5/42

Fraction of cities that have rivers = 29/42

The fraction of these 42 cities that have a lake or river running through them will then be:

= 5/42 + 29/42

= 34/42

= 17/21

Answer: y = 800

Step-by-step explanation:

3(y + 200) = 3000

3y + 3(200) = 3000

   3y + 600 = 3000

              3y  = 2400     [Subtract 600 from both side]

                y   = 800      [Divide 3 in both side to solve for y]  

Answer:

grape juice, orange juice, then apple juice

or the obvious choice

none of them are the best because none of them are good

Answer: b =50°

Step-by-step explanation:

The angles on a straight line =180°

180° = 50°+90°+b

180°-50°-90°=b

50° = b

Answer:

Step-by-step explanation:

∠b + ∠a + 50° = 180°

∠b + ∠90 + 50° = 180°

∠b = 180° - 90° - 50° = 40°

Answer:

14 marble

Step-by-step explanation:

here's your solution

=> Total number of marble = 35

=> ratio of David and Jason = 2 : 3

=> let the ratio be in x

=> now, 2x + 3x = 35

=> 5x = 35

=> x = 35/5

=> x = 7

=> number of marble with David = 7*2 = 14

=> number of marble with Jason = 7*3 = 21

hope it helps

Answer:

number of marbles that David had=

[tex]35 \times \frac{2}{5} \\ 14marbles[/tex]

Answer:

13

Step-by-step explanation:

here's your solution

=> base = 12

=> perpendicular = 5

=> we need to find hypotenuse = ?

=> we know , h^2 = p^2 + b^2

=> h^2 = 12^2 + 5^2

=> h^2 = 144 + 25

=> h^2 = 169

=> h= √169

=> h= 13

Answer:

Hidden question 1: How much change did Joshua get back after paying for his supplies.

Hidden question 2: How many puppies have spots?

(I hope this is what you meant by hidden questions. If you meant something like rearranging the words I am so sorry.)

Answer:

True.

Step-by-step explanation:

It is given that, a regular hexagon is dilated by a scale factor of 0.4 to make image.

It means, the perimeter of image is 0.4 times the perimeter of the original hexagon.

For example,

Let's take the rectangle with length of 12 and width of 4, it's perimeter is 12+12+4+4 =32

Let's find image using scale factor 0.4, we get

length =0.4(12)= 4.8

width =0.4(4)=1.6

So, perimeter of image = 4.8+4.8+1.6+1.6=12.8

If we compare the perimeters

0.4(32)=12.8.

So, it is true.

Answer:

(x - 1)² + 16

Step-by-step explanation:

Subtract 17 from both sides of the equation.

Use the formula (b/2)² to see which number you have to add to both sides.

Add 1 to both sides of the equation.

Factor the left side of the equation into a perfect square.

Add 16 to both sides of the equation.

(x - 1)² + 16 is the equation in standard form (x² - 2x + 17) rewritten by completing the square.

Answer:

1/2 or .5

Step-by-step explanation:

Hey There!

So the first step of this problem is to get y on one side and everything else on the other side

to do so we use inverse operations

so to get rid of the 2x we subtract 2x from each side

we would end up with -4y=5-2x

now want to get rid of the -4 on the y

to do so we would divide each side by -4

we would end up with

[tex]y=\frac{1}{2}x -\frac{4}{5}[/tex]

so we can conclude that the slope is 1/2 or .5

Answer:

Acute triangle

Step-by-step explanation:

All the three angles of the triangle is less than 90, all angles are acute. So, it is acute triangle.

If any one of the three angles is 90, then it is right triangle.

If any one of the three angle is more than 90, then it is obtuse triangle.
