Answer:

Explanation:

A linear line is a line that is straight going from left to right upwards or downwards. The only one that matches this description is B.

(Linear functions are those whose graph is a straight line. A linear function has the following form. y = f(x) = a + bx. A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y.)

Hope it helps!

If the discriminant is 16 in a quadratic equation what is true about its solutions

olganol [36]

If the discriminant is a positive number, there will be 2 possible solutions. If you replace the entire section of b²-4ac with 16, you will see that the equation becomes; (-b+-√16)/2a --> leading to an answer with the + and another with the -.

If the discriminant is 0, there will be 1 possible solution, (again replace this into the discriminant value) (-b)/2a ---> this formula is used to also find the x coordinates of a vertex, fyi.

If the discriminant is a negative number, there will be no solution (since squareroot of a negative number is not possible)

Hope I helped :)

Lisa's pet shop has 2 fish tanks.Tank A contains smaller fish who are fed 1 gram of food each per day.Tank B contains 2/3 the nu

Nutka1998 [239]

Answer:

Lisa will not be able to feed both tanks the same amount of food.

Step-by-step explanation:

This question is incomplete, here is the complete question :

"Lisa pet shop has 2 fish tank . Tank A contains smaller fish who were fed 1 gram of food each per day. Tank B contains larger fish who are fed 2 gram each per day. If tank B contains 2/3 the number of fish Tank A contains,will Lisa ever feed both tanks the same amount of food."

Let the number of fish in tank A = f

Lisa fed 1 gram of food each per day = f × 1 = f

So,the number of fish in tank B = $\frac{2}{3}f$

Lisa fed 2 gram of food each per day = $\frac{2}{3}f\times 2$

If both the tanks are fed with same amount of food then

$f=\frac{2f}{3}\times 2$

$f=\frac{4f}{3}$

⇒ 3f = 4f

⇒ 3 = 4

But 3 ≠ 4

Therefore, Lisa will not be able to feed both tanks the same amount of food.

Answer: 25

Step-by-step explanation: first find x; 60= 10x - 10, then subtract 10 from both sides to get 50, then divide by 5 to get 10, then plug it in to the equation of the side to get 25
