Answer:
(0, -3)
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
<u>Algebra I</u>
- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define systems</u>
x - 4y = 12
x - 5y = 15
<u>Step 2: Solve for </u><em><u>y</u></em>
<em>Elimination</em>
- Subtract 2 equations: y = -3
<u>Step 3: Solve for </u><em><u>x</u></em>
- Define original equation: x - 4y = 12
- Substitute in <em>y</em>: x - 4(-3) = 12
- Multiply: x + 12 = 12
- Subtract 12 on both sides: x = 0
Answer:
=615.44 m^2
Step-by-step explanation:
The area of the circle is given by
A = pi r^2
= pi (14)^2
= (3.14) 14^2
=615.44 m^2
20 ribbons
Explanation:
1st day— 5 ribbons
2nd day—2 x 5 = 10 ribbbns
3rd day— 2 x 10 = 20
Hope this helps
M<1 = M<3
these 2 angles are equal for parallel lines
6x=120
X=120/6=20
Answer:
y=2x+5
Step-by-step explanation:
y=2x+4 means that the slope is m1=2
A parallel line shall have the same slope so
m2=m1=2
Therefore, the equation of the new line will be
y=2x+q
where q is the y-intercept, that is 5 because the line must pass in (0,5), so
q=5
and
y=2x+5
