Since the first part says the value is five less then twice the square of a negative number we get the first equation as 2(-x)²-5. Then we have that -9x is equal to that previous equation. Therefore our new equation is 2(-x)²-5=-9x. We can move the nine over by adding it to both side to get 2(-x)²+9x-5=0. Then you can use any method of factoring (I prefer quadratic formula) to get your values for x. By doing so, you’ll get x=28 and x=-32.5. Since the problem said the number was negative in the first part, you know you can’t have the 28 as the answer so the right answer is -32.5.
Answer: my guess is 9000 grams
Step-by-step explanation:
so first convert 9 kilograms in to grams.
Then, convert those grams into jars.
They are NOT similar because similar triangles have congruent angles, but are different sizes. These angles are not congruent.
Answer:
8
Step-by-step explanation:
When a number is put in the parenthesises with x you substitute that number in every time you see x.
f(x)=5x-7
f(3)=5(3)-7
f(3)=15-7
f(3)=8
The answer is one. do you need an explanation or no
