Answer: With help of below explanation we can tell whose work is correct.

Step-by-step explanation:

Since, given expression is,  -3x+4=5x-6

⇒ -3x = 5x-6-4  ( By subtraction property of equality)

⇒-3x = 5x-10

⇒-3x-5x= -10  ( Again, By subtraction property of equality)

⇒-8x = -10

⇒8x=10           ( By multiplying -1 on both sides)

⇒x=10/8         ( By division property of equality)

⇒x=5/4

What is the y-value of the vertex of the function f(x)=-(x-3)(x+11)
lutik1710 [3]

so, this is a quadratic equation, meaning two solutions, and we have a factored form of it, meaning you can get the solutions by simply zeroing out the f(x).

\bf \stackrel{f(x)}{0}=-(x-3)(x+11)\implies 0=(x-3)(x+11)\implies x= \begin{cases} 3\\ -11 \end{cases} \\\\\\ \boxed{-11}\stackrel{\textit{\large 7 units}}{\rule[0.35em]{10em}{0.25pt}}-4\stackrel{\textit{\large 7 units}}{\rule[0.35em]{10em}{0.25pt}}\boxed{3}

so the zeros/solutions are at x = 3 and x = -11, now, bearing in mind the vertex will be half-way between those two, checking the number line, that midpoint will be at x = -4, so the vertex is right there, well, what's f(x) when x = -4?

\bf f(-4)=-(-4-3)(-4+11)\implies f(-4)=7(7)\implies f(-4)=49 \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ ~\hfill \stackrel{vertex}{(-4~~,~~49)}~\hfill

What percent of all patients are blood type AB? Round your answer to the nearest tenth of percent
Eddi Din [679]

Answer:

4.6%

Step-by-step explanation:

Here we are given a table providing us information regarding various blood groups of both males and females. Here from the table we can see that total number of people in the survey is 717. it includes =d all the blood group and both men and women.

Not let us see the number of people with blood groups AB.

From the table we can say that there are 33 people with AB blood grpup. Including men and women.

Hence our data to evaluate the percentage is 33 people with AB blood group among 717 people.

Hence percentage = \frac{33}{717}

Percentage = 0.046 approx

Percentage = 4.6

The time is took Tayna to complete different sets of math problems varied directly with the number of problems in the set Tayna'
Vsevolod [243]

Answer:

C

Step-by-step explanation:

time is directly proportional to the number of problems in the set

=> x = ky

k = constant of proportionality

when k = 12

x = 12y

by making y the subject, we divide both sides by 12

=> y = x/12
