2x − y = −4 → 10x − 5y = −20
3x + 5y = 59 → 3x + 5y = 59
13x = 39..... this is derived from adding the two equations on the right.
13x = 39 can be used in place of 3x + 5y = 59 in the initial system and will yield the same result.
A)
4(q - 10) = 76..... Tim earned 4 points for each correct answer, totaling 76 points. He got 10 answers right less than the total number of questions on the test.
b)
q = 10 + 76/4
q = 29
Thus, the overall number of questions on Tim's math test amounted to 29.
Answer:
The constant pay of $25 signifies the intercept
Step-by-step explanation:
To address this query, we first need to comprehend and relate it to the formula for a straight line.
i.e
this represents the line's equation
where m= slope
y= dependent variable
x= independent variable
c= intercept
Given

by comparing the two expressions, we can observe that
25 is equivalent to c, which denotes the intercept
