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:
Solve for x = all values of x are solutions

Step-by-step explanation:
Simplify the following:
(-2 (x + 5))/3 + 4 (x + 5) - (10 (x + 5))/3
Put each term in (-2 (x + 5))/3 + 4 (x + 5) - (10 (x + 5))/3 over the common denominator 3: (-2 (x + 5))/3 + 4 (x + 5) - (10 (x + 5))/3 = (-2 (x + 5))/3 + (12 (x + 5))/3 - (10 (x + 5))/3:
(-2 (x + 5))/3 + (12 (x + 5))/3 - (10 (x + 5))/3
(-2 (x + 5))/3 + (12 (x + 5))/3 - (10 (x + 5))/3 = (-2 (x + 5) + 12 (x + 5) - 10 (x + 5))/3:
(-2 (x + 5) + 12 (x + 5) - 10 (x + 5))/3
(12 (x + 5) - 10 (x + 5)) - 2 (x + 5) = 0:
0/3
0/3 = 0:
Answer: 0
In order to know how much of the 3/8 is in the 1/4, you calculate the quotient between 1/4 and 3/8, just as follow:
1/4 ÷ 3/8
you can convert the previous quotient into a multiplication by inverting the second fraction:
1/4 ÷ 3/8 = (1/4) x (8/3) = 8/12 = 2/3
Hence, 2/3 is what 3/8 is in 1/4
The slope-intercept form:
m - slope
b - y-intercept
We have the slope
and point (9, 7). Substitute:
<em>subtract 3 from both sides</em>

Answer:
<h2>700 (units
)</h2>
Step-by-step explanation:
Surface Area =2 length x width + 2 length x height + 2 height x weight
so we do:
7 x 12 = 84 84 x 2 = 168
7 x 14 = 98 98 x 2 = + 196
14 x 12 = 168 168 x 2= <u> + 336</u>
