Answer:

The student is completely incorrect because there is no solution to this inequality.

Step-by-step explanation:

We are given that an inequality

$\mid {x-9}\mid$

A student found the solution of given inequality are given by

$x-9>4$ and $x-9$

$x>13 \;and\;x$

We have to find the explanation by which the student is correct.

We know that

Mod means magnitude or distance of point which is always equal or greater than 0.

$\mid{x-9}\mid\geq0$

It can never be negative .

But we have $\mid{x-9}\mid$

Hence, the inequality is not correct therefore, there is no solution to this inequality.

Answer:

The student is completely incorrect because there is no solution to this inequality

Step-by-step explanation:

we have

$\left|x-9\right|\$

The left side $\left|x-9\right|$ always will be greater than or equal to zero

The inequality always will be not true

therefore

There is no solution to this inequality.

Write a linear equation in standard form for the line that goes through (4,4)and (8,3)

Alexus [3.1K]

The standard equation of a line has the form:

y=mx+b

Where m is the slope of the line and b is the intercept.

The only thing we need to determine the equation of a line is two points, in this case, we have the points (4,4) and (8,3). Then, from the first point we know that when x equals 4 y equals 4 and from the second point we know that when x equals 8 y equals 3, we can express this with the standard formula of a line, like this:

4=m*4+b and 3=8*m+b

subtraction the second expression from the second one, we get:

4-3=m*4+b-8*m-b, we can cancel b and then we have:

4-3=m*4-m*8, we can subtract 3 from 4 in the left side and 8*m from 4*m from the right side and then:

1= -4*m , we can divide both sides by -4 and then:

m= -1/4

Now that we know the value of the slope, we only need to specify the value of b, we can do this by replacing the value of m in the expression 4=m*4+b of the first point and then solve for b, like this;

4=m*4+b, m=-1/4, then:

4= 4*(-1/4)+b, then:

4= -1+b, then, adding -1 in both sides we have:

4+1=b, then:

b=5

And the standar form of the line would be:

y=(-1/4)*x+5

Work out the answer to this problem to reduce to the simplest form 5/8-1/2=

inysia [295]

In order to subtract fractions, you need the denominators (bottom number) to be the same. $\frac{1}{2} * \frac{4}{4} = \frac{4}{8}$ . $\frac{5}{8} - \frac{4}{8} = \frac{1}{8}$

I need help with a math question but apparently everyone is dead today..

Gwar [14]

The answer is D. I’m assuming this is surface area so here’s my explanation:) ok so the area of the triangle is 6 (4x3 divided by 2) and when you add the other triangle that’s 12. Ok so we have 12 so far. Then the area of the bottom rectangle is 24 (3x8). Then the area of the side rectangle is 32 (4x8). THEN the top rectangle’s area is 40 (8x5). When you add the numbers up (12+24+32+40) you get 108! And of course dont forget the cm2. ( centimeters squared ). :) I hope this helps
