Answer:
function 2
Step-by-step explanation:
Answer:
Her conjecture is not correct
Step-by-step explanation:
Given
For
Required
Determine if the conjecture is true
implies that the values of x are:
-2, -3, -4, -5.....
Take any value of x and substitute in
<em>Let x = -3</em>
becomes
The above inequality is false;
Hence:
<em>Her conjecture is not correct</em>
Answer:
L=15 W=12 15*12 = 180
Step-by-step explanation:
W*L = area
W*(W+3) = 180
Do the distributive
W^+3 W-180=0
Find 2 numbers that when multiplied ,the result is -180
and when added the result is 3
- 12* 15 = -180
-12 +15 = 3
Answer:
1/4
Step-by-step explanation:
7x-21+12-3x=-8
4x-9=-8
4x=1
x=1/4
Answer:
Step-by-step explanation:
If BOTH equations are in slope-intercept form then the-graphing-? method would be best, but the-substitution-? method would also be effective since both y's are already by itself.
If ONE of the equations is solved for x or y and the other equation is not, then the-substitution-? method is best.
If BOTH equations are lined up in standard form & the coefficients of x or y are opposites then the BEST method is definitely the-elimination--? method.
If BOTH equations are lined up in standard form the elimination method would be best. But if the coefficient of x or y is 1, then the-substitution--? method is also effective.
