Answer:

x = 35

Step-by-step explanation:

The marked consecutive interior angles are supplementary:

(x +12)° +(4x -7)° = 180°

5x +5 = 180 . . . . . collect terms, divide by °

x + 1 = 36 . . . . . . . divide by 5

x = 35 . . . . . . . . . . subtract 1

patriot [66]

Answer:

see below

Step-by-step explanation:

(3x+1)/2<−x+4

Multiply each side by 2 using the multiplication property of equality

3x+1 < -2x +8

Subtract 1 from each side using the subtraction property of equality

3x < -2x+7

Add 2x to each side using the addition property of equality

5x < 7

Divide each side by 5 using the division property of equality

x < 7/5

What is the gcf of 92 and 100

Elena-2011 [213]

$92= \textcircled{2} \times \textcircled{2} \times 23 \\
100=\textcircled{2} \times \textcircled{2} \times 5 \times 5 \\ \\
GCF(92,100)=\textcircled{2} \times \textcircled{2} =4$

The GCF of 92 and 100 is 4.

PLZ HURRY!!!!!!!!!!!!!<br> Simplify. <br> −4x^2(5x^4−3x^2+x−2)

Simora [160]

$\bold{Answer}$

$\boxed{\bold{-20x^6+12x^4-4x^3+8x^2}}$

$\bold{Explanation}$

$\bold{Simplify: \ -4x^2\left(5x^4-3x^2+x-2\right)}$

$\bold{------------------}$

$\bold{Distribute \ Parenthesis}$

$\bold{\left(-4x^2\right)\cdot \:5x^4+\left(-4x^2\right)\left(-3x^2\right)+\left(-4x^2\right)x+\left(-4x^2\right)\left(-2\right)}$

$\bold{Apply \ Addition \ / \ Subtraction \ Rules: \ +\left(-a\right)=-a,\:\:\left(-a\right)\left(-b\right)=ab}$

$\bold{-4\cdot \:5x^4x^2+4\cdot \:3x^2x^2-4x^2x+4\cdot \:2x^2}$

$\bold{Simplify \ -4\cdot \:5x^4x^2+4\cdot \:3x^2x^2-4x^2x+4\cdot \:2x^2: \ -20x^6+12x^4-4x^3+8x^2}$

$\bold{-20x^6+12x^4-4x^3+8x^2}$

$\boxed{\bold{Eclipsed}}$

The solutions to a function are what points on the coordinate plane when you graph the line?

vodka [1.7K]

The solutions to a function are the points where the graph of the function crosses the x-axis, but only if the solutions are real numbers. If the function has imaginary solutions, then you don't see those on the graph.
