Answer:
1. y = 0, b/a
2. y = 0, a/b
3. y =0, c/b
4. y =0, c/a
Step-by-step explanation:
The slope formula for y = mx + b which is known as standard form is Ax + By ≥ C
slope = A/B
x-intercept = C/A
y-intercept = C/B
and now we are dueling with y, so we will use y-intercept
1. cx + ay = b
where c is x, a = y and b=c
Y-int = C/B
y = 0, b/a
2. cx + by = a
y = 0, a/b
3. ax + by = c
y =0, c/b
4. bx+ ay = c
y =0, c/a
Hope this helps
Answer: 8.55 feet
Step-by-step explanation:
We should equal the average depth to 1, so if it raises 3%, it raises 0.03. Simply add the original (1) plus what it rose (0.03) and multiply the original by that, so 8.3 × 1.03 = new depth. The result is 8.549 feets.
All angles are congruent.
The sum of the measures of the interior angles of a quadrilateral is 360.
Since all angles are congruent, then each angle must measure 360/4 = 90.
Every angle measures 90 degrees.
The quadrilateral must be a rectangle.
Is the quadrilateral also a square?
We are told "<span>opposite sides that are congruent." Since only opposites sides are congruent, and not all sides are congruent, then it is a rectangle, but not necessarily a square.
Answer: B. rectangle

2 times the cube root of 8x+9=5
divide both sides by 2
cube root of 8x+9=2.5
cube everybody (put to 3rd power)
8x+9=2.5^3
8x+9=15.625
minus 9 both sides
8x=6.625
divie both sides by 8
x=0.828125
