Answer:

The answer is 2876.25

Step-by-step explanation:

The question said x is ten

so 7x means 7*10

93x means 93×10

divided by 3.2x which means 3.2x which is 3.2×10

when u write it in an equation format it will look like this 70+930÷32

Ur answer should look like this 2976.25

Answer:

The answer is 31.25 or 125/4 or 31 1/4 .

Step-by-step explanation:

You have to substitue x = 10 into the expression :

\frac{7x + 93x}{3.2x}

=  \frac{100x}{3.2x}

Let x = 10,

\frac{100(10)}{3.2(10)}

=  \frac{1000}{32}

=  \frac{125}{4}

= 31.25

I NEED HELP PLEASE, THANKS! :)
Allushta [10]

Answer:

2nd option: (0.5, 7), maximum; (2, 1) point of inflection; (3.5, -5), minimum.

Step-by-step explanation:

The maximum point, or a point of the graph with the highest y-value, is at

(0.5, 7).

The minimum point, or a point of the graph with the lowest y-value, is at

(3.5, -5).

The point of inflection is where the graph begins to change direction. This is at (2, 1).

Therefore, the 2nd option is correct.

Find an equation for the line perpendicular to the line −4x+3y=−2having the same y-intercept as −7x−7y=6
SCORPION-xisa [38]

First we need to find slope of given line −4x+3y=−2

So convert it into slope intercept form y=mx+b

−4x+3y=−2

3y=4x−2

y=4/3x−2/3

Comparing above equation with y=mx+b gives m=4/3

Hence slope of given line is 4/3.

<em>We need slope of perpendicular line which is always "negative reciprocal of given slope"</em>.

Negative of 4/3 is -4/3.

taking reciprocal gives -3/4

Hence slope of required perpendicular line is m=-3/4

-------

Now we need to find y-intercept of −7x−7y=6

y-intercept is always the y-value when x=0 so let's plug x=0 into −7x−7y=6

−7(0)−7y=6

0−7y=6

−7y=6

y=-6/7

y-intercept is also called "b" in y=mx+b

hence b=-6/7

-----

Now we know that slope of perpendicular line is m=-3/4 and y-intercept b=-6/7

so plug both into formula y=mx+b

We get Final answer is y=-\frac{3}{4}x-\frac{6}{7}
