Answer:
.70 8.40 divided by 12 because a dozen is equal to 12
Rearrange the equation so the left side starts out as y =
5x + 3y = -4
3y = -5x - 4
y = (-5/3)x - (4/3)
the slope is in front of the x and the y-intercept iis the other number
slope is -5/3
y-interxept = -4/3
For the 1st pattern is adding 5 to each number. for 2nd pattern it is adding 8 to each number.
Answer:
17.861 feet or 17.9 feet (3 sf)
Step-by-step explanation:
180 - 36 - 87 = 57
X/sin(87) = 15/sin(57)
X = 17.861 feet
Option 1: Graph both equations to see where they intersect. If they do not intersect at lattice points, then use the substitution method.
Option 2: Use substitution method of system of equations
Equation of a circle: (x-h)² + (y-k)² = r²
Choose one of the equations and solve for one of the variables
(I am choosing to solve for y)::
(y-k)² = r² - (x-h)²
|y - k| = √(r² - (x-h)²)
y - k = +/- √(r² - (x-h)²)
y = k +/- √(r² - (x-h)²)
Now, substitute k +/- √(r² - (x-h)²) for y into the other equation to solve for x.
Substitute those x values into y = k +/- √(r² - (x-h)²) to solve for y.
Hope this makes sense!
