Answer:
Vertex (-2,-9)
zeros: x=1, x=-5
y-intercept: -5
Step-by-step explanation:
When you graph the quadratic equation you obtain the parabola shown in the figure attached.
Find the vertex of the parabola observing the graph, you can that the minimum point of the parabola is at (-2,-9) this is the vertex.
The zeros are the x-intercepts:
x=1; x=-5
And the y-intecept is when x=0 and the parabola cut the y-axis. This is: -5.
Answer:
x + 3 = 7/2
100x = 50
16/x = 24
Step-by-step explanation:
The value of x is 1/2 in the three equations.
The variable x is in the left side of the equations.
You multiply 4 by 3 because he got 4 stamps each week for 3 weeks. That leads to it being 12 stamps in total.
He wants 6 stamps out of 12 on each page of his album, so you divide 12 by 6 and get two.
He will use 2 pages.
The tools used were mathematical reasoning, multiplication and division.
Answer: Last Option
Step-by-step explanation:
By definition the sum of the internal angles of a triangle must always be equal to 180 °.
This means that:
Now we solve the equation for the variable x
We subtract 12 in both barks of the equation
Divide by 3 on both sides of the equation
Finally the measure of angle ABC is: (56-5)° = 51°
