A soccer player gets 2 points for a goal and 1 point for an assist. If the combined number of goals and assists that a player has is 24 , and the total number of points that the player has is 42 , which system of equations can be used to determine the number of goals and assists the player has? Assume g represents the number of goals and A represents the number of assists.
Serina wants to solve the following system of equations in the most efficient way. 2 x plus 3 y is equal to 18 x plus 7 y is equal to 31 She plans to solve for x in the first equation as her first step since both 2 and 3 can be divided into 18 Why is Serina mistaken?
Which statements about this system of equations are true? Choose three correct answers. 2 x minus 7 y is equal to negative 13 negative 2 x plus 11 y is equal to 1
What is the solution to the system of equations? y is equal to 1 half x plus 6 and y is equal to negative 3 fourths x minus 4
Sierra is selling bracelets to raise money for the Language Club at school. Each bracelet with yellow beads sells for 5 dollars Each bracelet with orange beads sells for 6 dollars She raised 660 dollars for the club. The number of bracelets with yellow beads that Sierra sold is 8 more than twice the number of bracelets with orange beads. Let y represent the number of bracelets with yellow beads and r represent the number of bracelets with orange beads. Which system of equations will solve for the number of each type of bracelet sold?
Arnoldo needs to write this system in slope-intercept form. Which shows how he could do that? 3 x minus 2 y is equal to 6 0 point 4 times open paren 20 y plus 15 close paren is equal to x
Which statements are true regarding the system of equations? Choose four correct answers. 4 x plus 5 y is equal to 15 28 x plus 35 y is equal to 105
In the given system of equations, which variable would be easiest to solve for? x plus 4 y is equal to 14 3 x plus 2 y is equal to 12
Consider this system of equations. Which equation represents the first equation written in slope-intercept form? 5 x minus 2 y is equal to 10 y is equal to 1 fourth x plus 1
The equations in this system were added to solve for x. What is the value of x? the 3 by 1 matrix row 1, negative 8 x plus 8 y equals 8 row 2, 3 x minus 8 y equals negative 18 over horizontal bar row 3, negative 5 x equals negative 10
In one hour, a bakery sold 5 muffins and 9 bagels for total of $25.50. The next hour, the bakery sold 3 muffins and 12 bagels for a total of $28.50. Let m represent the price of one muffin and b represent the cost of one bagel. Draco wrote the following system of linear equations to solve for the cost of each item. 5 m plus 9 b is equal to 28 point 5 0 3 m plus 12 b is equal to 25 point 5 0 What is Draco’s error?
A system of equations is given. y is equal to negative 3 x plus 6 and y is equal to 6 minus 3 x Which of the following statements best describes the two lines?
What is the slope of each line? Line cap A : y is equal to negative 4 x plus 5 Line cap b : y is equal to 3 x plus 1
Bryce took a quiz that consisted of true-or-false questions and multiple-choice questions. The true-or-false questions were worth 1 point each, and the multiple-choice questions were worth 2 points each. Bryce only knows that he answered 8 questions correctly and earned a total of 14 points. To determine the number of each type of question that he answered correctly, he wrote the system of linear equations x+y=8 and x+2y=14. Which ordered pair is a solution to this system of linear equations, and what does the ordered pair represent?
