4 0

Answer:

slope = -3, y-intercept y = -2

Step-by-step explanation:

  • Make y the subject of the line 2y + 4 = - 6x
  • Divide throughout by two to get the slope of the graph as -3.
  • Substitute x = 0 to get the y - intercept as y = -2

What’s the length of the hypotenuse in inches?
natta225 [31]

Answer:

The hypotenuse is 25 inches.

Step-by-step explanation:

This is a right triangle, so the Pythagorean Theorem applies.

I will assume you know about the Pythagorean Theorem, therefore I will not define it.

Here, I am solving for the hypotenuse.

a^2+b^2=c^2

24^2+7^2=c^2

576+49=c^2

625 = c^2

25=c

You buy 4 breakfast sandwiches at $2.59 each, 4
Paha777 [63]

Answer:

all 4 meals equal $20.95

Step-by-step explanation:

4 sandwiches = $2.59 each

4 hashbrowns = $1.10 each

4 orange juice = $1.25 each

sales tax = 6%

now you have two options you could either add all of the one meal prices together or you could do how much it would cost for the each individually

adding one meal

2.59 + 1.10 + 1.25 = 4.94

4.94 x 4 = 19.76

adding all the items individually

2.59 x 4 = 10.36

1.10 x 4 = 4.40

1.25 x 4 = 5.00

10.36 + 4.40 + 5.00 = 19.76

now if the sales taxes

19.76 x 0.06 = 1.19

now sales taxes plus all the items

19.76 + 1.19 = 20.95

Find the measure of A.18<br> B.54<br> C.36
prisoha [69]

Answer:

[A] 18

Explanation:

[I'm assuming you want us to find the measure of ∠ABC]

∠ABC is a right angle, meaning ∠ABD and ∠DBC added together must equal 90°

2x° + 3x° = 90

2x + 3x = 5x

5x = 90

5x / 5 = 90 / 5

x = 18
