Answer:
A
Step-by-step explanation:
youre looking for the total spent, and then each variable from the word equation
Answer:
c = 22
Step-by-step explanation:
x^2 + c = 103 so if x is either + or - 9, x^2 = 81 so...
81 + c = 103
c = 22
Answer:
1. algebraic expression: a mathematical expression containing one or more variables
2. coefficient: the constant preceding the variables in a product
3. constant: a numerical value
4. expression: a mathematical phrase that cannot be determined true or false
5. variable: a letter or symbol used to represent an unknown
Step-by-step explanation:
Answer:
y = -5x - 21
Step-by-step explanation:
Given in the question,
equation of a parallel line
y = -5x + 6
point through which it passes
(-4,-1)
Step1
Find the gradient of the equation given, as it is parallel so it will have same gradient
equation of straight line
y = mx + c
where m is gradient
c is y intercept
y = -5x + 6
m =-5
Step2
Find y-intercept
-1 = -5(-4) + c
-1 = 20 + c
c = -20 - 1
c = -21
Step3
form the equation
y = -5x - 21
