Answer:
OPTION 4
Step-by-step explanation:
Let the three consecutive numbers be n, (n + 1) and (n + 2).
Note that the largest number of the three is (n + 2) and the smallest is n.
So, according to the given data, the sum of all the three integers is equal to 1 more than twice more than the largest number.
Writing it mathematically, we have:
n + (n + 1) + (n + 2) = 12 + 2(n + 2)
This is OPTION (4) and is the answer,
24x = 2,2,2,3,x
18y = 2,3,3,y
Answer:
Y= -12x + 150
Step-by-step explanation:
1. You do the change in y over the change in x to get the slope.
y1 - y2 / x1 - x2 and you get the slope of -12
2. Making a point-slope form equation
y-y1=m(x-x1)
y-138= -12(x-1)
3. Turning point-slope form equation to slope-intercept
y-138= -12(x-1)
distributive property
y-138=-12x+12
add 138 on both sides
<h2><u>
y= -12x+150</u></h2>
Standard form of a quadratic f(x) = ax^2 + bx + c
In a quadratic function you find the vertex using the formula x = -b/2a; once you find the x value, substitute it into the equation and solve for y.
To know if a parabola opens up or down you look at the coefficient of the x^2 term. If it is positive, the graph opens up; if it is negative, the graph opens down.
5+3x=4x
only when
x=5
The two expression are only equal at x=5
