Given a number "x"
ten times this number is : 10x
one-half the sum of the number and three= 1/2(x+3)
Therefore:
The equation will be:
10x=1/2(x+3)
20x=x+3
20x-x=3
19x=3
x=3/19
Answer: the equation is : 10x=1/2(x+3) and the number is 3/19.
Answer:
B)
Step-by-step explanation:
We are given,
The graph of the parabola opens downwards.
This means that the leading co-efficient of the function will be negative.
So, options C and D are not possible.
Moreover, it is given that the graph cuts x-axis near i.e. = 1.5 and i.e. = 4.5.
i.e. At y=0, the value of x is near and .
A. So, in , we put y =0.
i.e.
i.e.
i.e. x = 0.68 and x = 3.41
We see that this does not crosses the x-axis at the given points.
So, option A is wrong.
B. Also, in , we put y =0.
i.e.
i.e.
i.e. x = 1.68 and x = 4.41.
Thus, this equation cuts the x-axis near the given points i.e. 1.5 and 4.5.
Hence, the equation of the given graph is .
Answer:
19 squared units
Step-by-step explanation:
To find the area of the figure, you can simply count the number of squares that are shaded. I counted a total of 19 squares, meaning that the total area of the shaded figure is 19 units squared.
