Answer:

The ladder meets the wall at 17.29 feet from the ground.

Step-by-step explanation:

Pythagorean Theorem ⇒ a^2 + b^2 = c^2

5^2 + b^2 = 18^2

25 + b^2 = 324

b^2 = 299

b = 17.291616

When solving a system of two equations via substitution, there will always be only one answer.
sertanlavr [38]
No false.
Remember the solution(s) to a system of equations is where the graphs all intersect if at all.
For the case of say a system of 2 lines, you can see the different possible outcomes..
  -- If the two lines intersect at some point (x,y), that is one unique solution
  -- If the two lines are parallel to each other, you see there are no intersection points and therefore this system of two parallel lines has no solutuion.
  -- If the two lines overlap, really the same line written as a multiple of the other line, then you see they intersect at all points along the line, here there are infinite solutions.

Ann increased the quantities of all the ingredients in a recipe by 60% 60, percent. She used 808080 grams (g) of cheese. How muc
Alexus [3.1K]

Answer:

50 gram

Step-by-step explanation:

The actual percentage recipe = 100%

Percentage Increase in recipe = 60%

Recipe used as a result of increment = 80 gram

Hence,

100% + 60% = 80

160% = 80g

If :

160% = 80

100% = x

Cross multiply

1.6x = 80 * 1

1.6x = 80

x = 80 / 1.6

x = 50

Recipe required 50 gram

Identify an equation in point-slope form for the line perpendicular to y =3/4x -4 that passes through (-1, 7).
PilotLPTM [1.2K]

Answer:

y - 7 = -4/3(x + 1)

Step-by-step explanation:

<u>Given</u>

  • y =3/4x -4
  • (-1, 7)

<u>Convert to point slope form</u>

y - y1 = m(x - x1)

m: represents what the slope is

y - 7 = -4/3(x + 1)

<u>Distribute -4/3</u>

-4/3 * x = -4/3x

-4/3 * 1 = -4/3

y - 7 = -4/3x - 4/3

<u>Add seven in both sides</u>

21/3 -4/3 = 17/3

y = -4/3x + 17/2

<u>Answer</u>

linear equation: y = -4/3x + 17/2

point-slope form: y - 7 = -4/3(x + 1)
