What is the coefficient of x in the expansion of (2x−4)^2?

What is the coefficient of x^2 in the expansion of (x+3)(x^2+7x+8)?

Answers

Answer 1

Answer:

[tex]-16[/tex], [tex]10[/tex]

Step-by-step explanation:

To get the coefficients, we first need to factor the expressions

[tex](2x-4)^{2}[/tex]

[tex](2x-4)(2x-4)[/tex]

[tex]4x^{2}-16x+16[/tex]

The coefficient of x is -16

[tex](x+3)(x^{2}+7x+8)[/tex]

[tex]x^{3}+10x^{2}+29x+24[/tex]

The coefficient of x² is 10

Solve the inequality.

2x ≤ 3/2

Answers

Answer:

x ≤ [tex]\frac{3}{4}[/tex]

Step-by-step explanation:

Given

2x ≤ [tex]\frac{3}{2}[/tex] ( multiply both sides by 2 to clear the fraction )

4x ≤ 3 ( divide both sides by 4 )

x ≤ [tex]\frac{3}{4}[/tex]

Answer:

[tex] \sf \: x \leqslant \frac{3}{4} [/tex]

Step-by-step explanation:

Given equation,

[tex] \sf \rightarrow \: 2x \leqslant \frac{3}{2} [/tex]

Now the value of x will be,

[tex] \sf \rightarrow \: 2x \leqslant \frac{3}{2} [/tex]

[tex] \sf \rightarrow \: x \leqslant \frac{3}{2 } \times \frac{1}{{{2}}} [/tex]

[tex] \sf \rightarrow \: x \leqslant \frac{(3 \times 1)}{(2 \times 2)} [/tex]

[tex] \sf \rightarrow \: x \leqslant \frac{3}{4} [/tex]

Hence, the value of x is 3/4.

Your multiple-choice selection has a typo. Notice that choice b and d is the same answer.

For at most we use the (<) symbol.

$3 per apple = 3x.

$2 per orange = 2y.

find the slope of the line that passes through (-6, -2) and (-7, -2)

Answers

Answer:

[tex]0[/tex]

Step-by-step explanation:

We could use the Slope Formula to find the answer, but there's an easier way of doing it. Notice that the y-coordinates of both points are the same. This means that the line that passes through these points is horizontal, which makes our answer [tex]0[/tex] because all horizontal lines have a slope of [tex]0[/tex].

All horizontal lines have a slope of [tex]0[/tex] because the value of y never changes as the value of x changes, so if we were to input any two points on a horizontal line into the Slope Formula, our numerator would be [tex]0[/tex] (because anything subtracted from itself is [tex]0[/tex]), leaving us with a result of [tex]0[/tex] regardless of the denominator since [tex]0[/tex] divided by anything is [tex]0[/tex]. Hope this helps!
