If we expand bx to jx and kx we have:
5y^2-2y-7
5y^2-7y+5y-7 then factor...
y(5y-7)+1(5y-7)
(y+1)(5y-7)
So the other factor is:
(y+1)
310-95 is 215. You start with what you know, the starting expenses. If you spend x amount of money, you are left with 95 dollars. 310-95 is 215
Answer:
C. (3, -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>
7x + 3y = 12
7x - 3y = 30
<u>Step 2: Solve for </u><em><u>x</u></em>
- Eliminate <em>y</em>: 14x = 42
- Isolate <em>x</em>: x = 3
<u>Step 3: Solve for </u><em><u>y</u></em>
- Substitute in <em>x</em>: 7(3) + 3y = 12
- Multiply: 21 + 3y = 12
- Isolate <em>y</em> term: 3y = -9
- Isolate <em>y</em>: y = -3
And we have our final answer!
Answer:
height is 5 units
Step-by-step explanation:
We are required to determine the height of a triangle that has an area of 30 square units and a base measuring 12 units.
The formula for the area of a triangle is given as;
We plug in the given values and solve for the height;
I believe the answer is D. 150 per hour
hope this helps!!
