Answer:
Step-by-step explanation:
13
For one and only 1 real solution, the discriminant = 0 (see chart attached)
<span>So we know b^2-4ac=0 when the equation is in the format of ax^2+bx-c=0. Make sure your equation is in the right format first!</span>
<span>Given kx^2+12x-4=0 </span>
<span>b=12 </span>
<span>so b^2-4ac=0 </span>
<span>144 = 4ac </span>
<span>144 = 4(k)(-4) </span>
<span>144/(-16) = k </span>
<span>k = -9</span>
The expression deduced from the sentence is
<em>Five</em> <em>more</em> indicates addition. (
)
<em>Product</em> <em>of a number x and five</em><em> </em>means multiplication. (
)
<em>Is y</em><em> </em>designates equality operator (
)
Hope this helps.
1) You need to convert everything in the table to a whole number.
Some of the numbers are already convetted and listed. For the ones that aren't, you have to put them in.
If you need more help, ask :)
