4 and 5 because it is between those numbers
Answer:
x < 2
Step-by-step explanation:
Let's actually solve the given inequality 3x + 1 < 7. First we want to combine the constants into one: 3x < 6. Solving for x, we get x < 2.
The graph you have chosen as your answer is correct. x does not equal 2, but rather is less than 2, as the given inequality states. Since x is less than 2, we start at the (open) circle at 2 and move to the left.
The value of 5 ∙ 23 is 115.
The small dot is typically used as a multiplication symbol. When we multiply these two numbers the result is 115.
Answer:
For the linear equation y = mx + b, m is the slope (the change in y for a change in x) and b is the y intercept, i.e. the value of y when x is zero. For this problem, b (y-intercept) is the money Nicole would make even if the hours she babysits was zero, i.e. the flat fee. Therefore, b = $3. The slope m is the money she makes babysitting per hour, i.e. $5. Therefore, the equation is
y = 5*x + 3.
In function notation we just replace y with f(x) (meaning the output of the function f for input x):
f(x) = 5*x + 3.
In five hours (x = 5), Nicole would make:
y = 5*5 + 3 = 25 + 3 = $28.
Step-by-step explanation: :)
M=-5/2
B=-2
Y=-5/2x-2
X intercept=-4/5
