Answer:
The number is 3.
Step-by-step explanation:
5x - 4 = 11
5x = 15
x = 3
Answer:
Step-by-step explanation:
we know that
The roots of the quadratic function (x-intercepts) are
x=-1 and x=5/3
so
we can write the equation of the parabola as
where
a is a coefficient
Remember that
The parabola pass through the point (5,40)
substitute the value of x and the value of y of the ordered pair in the quadratic equation and solve for a
x=5, y=40
substitute
apply distributive property
see the attached figure to better understand the problem
The correct choices based on the integers are: 1a, 2b, 3d, and 4c.
In the question, we are asked to match the scenarios to their corresponding boundaries.
- miles traveled by a car in one hour: this can be non-negative numbers as the distance traveled by a car cannot be negative, but it is not infinitely possible, making the right option a. numbers between 0 and 70.
- average Celsius temperature in Antarctica: is mostly negative, and even if positive, very low. making the right option b. numbers between -100 and 20.
- amount of money owed on a car: this can be any non negative number without limit, making the right option d. no negative numbers.
- age when a baby takes their first step: as its an age it wont be a negative number, and its a baby age so it will be very small, making the right option, c. no negative numbers and positive numbers less that 2.
Thus, the correct choices based on the integers are: 1a, 2b, 3d, and 4c.
