If 5x + X^2 > 100, Then X Is Not? | Yahoo Answers ~ Lifestyle News

Rearrange the equation by subtracting what is to the right of the greater than sign from both sides of the inequality : 5*x+x*(2)-(100)>0 . Step by step solution : Step 1 : 1.1 Divide both sides by 7 x-(100/7) > 0. Solve Basic Inequality : 1.2 Add 100/7 to both sides x > 100/7 Inequality Plot : 1.3 Inequality plot for 7.000 x - 100.000 > 05x + x² > 100. x² + 5x - 100 > 0. Using the quadratic formula, solve x² + 5x - 100 = 0: x = 7.808. or. x = -12.808. Now that you have the zeros, draw the parabola on a graph and then decide whether you want the area between the two x-values or outside of them.If you plug in each answer for the value of x, then answer C (the number 7) is the only one that works. If 5x + x^2 cannot be greater than 100, then 5(7) + (7)^2 = 84, which is less than 100. All other answers give a number greater than 100, which makes the inequality work.5x + x² > 100. If you want to find out which values of "x" does NOT make this true, then let's solve this: 5x + x² ≤ 100. Put this into standard form:Free Online Scientific Notation Calculator.

If 5x + x² > 100, then x is not? | Yahoo Answers

Solve for x 5x-17=-x+7. Move all terms containing to the left side of the equation. Tap for more steps... Add to both sides of the equation. Add and . Move all terms not containing to the right side of the equation. Tap for more steps... Add to both sides of the equation. Add and . Divide each term by and simplify.By inspection, 7 is the smallest number. 5x and x² will be positive numbers so it makes sense the smallest sum will be from the smallest number. 5(7) + 7² = 35 + 49 = 84. That is NOT greater than 100. You can test the next biggest number to confirm it IS greater than 100. 5(8) + 8² = 40 + 65 = 105. Answer: 75x - 17 = -x + 7 . Add x to both sides of the equation. 6x - 17 = 7 . Add 17 to both sides of the equation. 6x = 24 . Divide both sides by 6 .If 5x + x² > 100, then x is not Thank you. Found 2 solutions by ewatrrr, solver91311: If 5x + x² > 100 then x^2 + 5x -100 > 0 and x is not in the interval [-12.81,7.81] f(x) = x^2 + 5x -100 x-intercepts: (7.81,0) and (-12.81) Answer by solver91311(24713) (Show Source): You can put this solution on YOUR website!

If 5x + x² > 100, then x is not? | Yahoo Answers

Solve for x 5x+x^2>100. Move to the left side of the equation by subtracting it from both sides. Convert the inequality to an equation. Use the quadratic formula to find the solutions. Substitute the values , , and into the quadratic formula and solve for . Simplify. Tap for more steps...Divide 3, the coefficient of the x term, by 2 to get \frac{3}{2}. Then add the square of \frac{3}{2} to both sides of the equation. This step makes the left hand side of the equation a perfect square.Step by step solution : Step 1 : Equation at the end of step 1 : 5x 2 + 100 = 0 Step 2 : Step 3 : Pulling out like terms : 3.1 Pull out like factors : 5x 2 + 100 = 5 • (x 2 + 20) . Polynomial Roots Calculator : 3.2 Find roots (zeroes) of : F(x) = x 2 + 20 Polynomial Roots Calculator is a set of methods aimed at finding values of x for which F(x)=0the x2 can be rewritten as 2x because the order of multiplication doesn't matter. combine the 5x and 2x into 7x. the equation is now 7x > 100 so just divide by 7. because its not negative the sign stays the same, and the result is irrational so i kept it in a fraction for simplicity. so x is not anything less than or equal to 100/7If 5X + x squared > 100 then x is not equal to Melissa. Jul 16, 2015 . Online "^" is used to indicate an exponent, e.g., x^2 = x squared. Could be any of a multitude of numbers. What are your choices? PsyDAG

Answer is 7

x² + 5x - 100 > 0

Using the quadratic serve as for x² + 5x - 100 = Zero we get:

x = (-5 ± √425)/2

The decimal approximations are x = -12.Eight and x = 7.8

So, the solutions to x² + 5x - 100 > Zero are x < -12.8 or x > 7.8

Therefore, if x is 8, Nine or 10 the inequality does dangle true.

Hence, x is not 7
