Yo JadedMulan! Help please: (1) What is the is the solution set to the equation -x^2-4x-5=0 (SHOW WORK PLZ)

(2) What is the equation of the line that passes through the vertex and y-intercept of this function?

(3)For a class picnic, two teachers went to the same store to purchase drinks. One teacher purchased 18 juice boxes and 32 water bottles and spent $19.92. The other teacher purchased 14 juice boxes and 26 bottle of water and spent $15.76.

Write a system of equations to represent the costs of a juice box, j, and a bottle of water, w. (SHOW WORK PLZ)

(b) Kara said that the juice boxes might have cost 52 cents each and that the bottles of water might have cost 33 cents each. Use your systems of equations to justify that Kara’s prices are not possible

(c) Solve your system of equations to determine the actual cost, in dollars, of each juice box and each bottle of water.

3; 9 is 8 to -4

step-by-step explanation:

the number of the people going.

step-by-step explanation:

the cost to buy one movie ticket is $7. if the total cost for the movie is a function of how many people go, then the input is : the number of the people going.

definitely a. the others have almost all data points on one side of the line.

step-by-step explanation:

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
