Please find which quadratic equation matches the graph with work attached

lesya [120]

Answer:

Step-by-step explanation:

Firstly, we know that the function must be negative due to its shape. This means that the answer cannot be B

Next we can use the equation $x=\frac{-b}{2a}$ that is used in order to find the vertex of the parabola.

$f(x)=-x^2+6x+7\\a=-1,b=6,c=7\\\\x=\frac{-6}{-2} \\x=3$

As the vertex is at x=3 on the graph, this one could be a contender.

$f(x)=-x^2+6x-7\\a=-1,b=6, c=-7\\\\x=\frac{-6}{-2} \\\\x=3$

This also could be the equation

$f(x)=-x^2-6x-7\\\\a=-1, b=-6, c=-7\\\\x=\frac{6}{-2} \\\\x=-3$

This rules option D out.

For this last step, we can look at where the zeroes would be for each equation. (These values are irrational, so we cannot look at specific number)

$f(x)=-(x^2-6x-7)$

As this equation has a negative value for c, this means that one zero must be positive and the other must be negative.

This means that option A can be ruled out

$f(x)=-(x^2-6x+7)$

As this equation has a positive value for c, this means that both of the zeroes must be positive. This means that it is the only one that fits all of the criteria.

HELP ASAP PLZ PLZ PLZ I GIVE BRAINLIEST

Yuki888 [10]

Answer:

Step-by-step explanation:

We can see that the base TA is 4, and the second base RS is 2. We can see that the height is 4. The area of a trapezoid is:

$A=\frac{h(b_1+b_2)}{2}$

Using this, we can substitute, and get:

$A=\frac{4\cdot(2+4)}{2} = \frac{24}{2} = 12$

Hope it helps!!

Two cans of soup cost $0.88. One can costs $0.20 more than the other can. How much would 5 cans of each type of soup cost all to

DochEvi [55]

We can determine that there are two types of soup: one can costing $0.54, and the other costing $0.34. 5 cans of the $0.54 soup would cost a total of $2.70, while 5 cans of the $0.34 soup would cost $1.70. Therefore, the combined cost of all 10 cans of soup, being 5 of each type, is $4.40.
