It can be helpful to graph the system. The appropriate choice is ...
... (0, 2) and approximately (1.91, 0.09)
Such a system of equations has no algebraic solution. Some graphing calculators will identify the points of intersection of the graphs to full calculator precision. Others can help you iterate a solution, if you need better accuracy.
Answer:
20 servings
Step-by-step explanation:
Four quarters per pound
5(4)=20
Slope intercept form is y = mx + b.....so lets solve for y
9x - 7y = -7 .....subtract 9x from both sides
-7y = -9x - 7...now we divide both sides by -7
y = 9/7x + 1 <==
Answer:
Mr. Miles’s statement is NOT reasonable
Explanation:
If Mr. Miles uses 2 1/10 pounds of clay for each model, Mr. Miles will have used a total of 6.3 pounds of clay.
The decimal form of 7 7/8 is 7.875, so 7.875 minus 6.3 will give you the amount of clay Mr. Miles has left over.
7.875 - 6.3 = 1.575
This means that Mr. Miles statement is not reasonable, as he only has about 1.6 pounds of clay left, not 3.
Answer:
u = -2, -3/5
General Formulas and Concepts:
<u>Algebra I</u>
- Standard Form: ax² + bx + c = 0
- Factoring
- Finding roots
Step-by-step explanation:
<u>Step 1: Define equation</u>
5u² + 6 = -13u
<u>Step 2: Solve for </u><em><u>u</u></em>
- Rewrite: 5u² + 13u + 6 = 0
- Factor: (u + 2)(5u + 3) = 0
- Find roots: u = -2, -3/5
