Which inequalities are true? Check all that apply. Three-fifths < 0 Four-sixths greater-than one-half Nine-elevenths < 1 T

Kipish [7]

$\frac{3}{5} < 0$

$\frac{8}{16} > \frac{1}{2}\\\\$

Solution:

We have to find the inequalities that are true

Option 1

$\frac{3}{5} < 0\\\\0.6 < 0$

0.6 is not less than 0

Thus this inequality is not true

Option 2

$\frac{4}{6} > \frac{1}{2}\\\\0.667 > 0.5$

0.667 is greater than 0.5

Thus this inequality is true

Option 3

$\frac{9}{11} < 1\\\\0.818 < 1$

0.818 is less than 1

Thus this inequality is true

Option 4

$\frac{8}{16} > \frac{1}{2}\\\\$

0.5 = 0.5

Thus the above inequality is not true

Reduce 7y + 2y 2 - 7 by 3 - 4y.

NARA [144]

Answer:

D. $2y^2+11y-10$ .

Step-by-step explanation:

Given:

We need to reduce $7y+2y^2-7$ by $3-4y$

Solution:

To reduce the equation means we need to subtract the one equation from other.

First we will arrange the equation n proper format we get;

$2y^2+7y-7$ ⇒ equation 1

Also Arranging other equation we get;

$-4y+3$ ⇒ equation 2

Now we will subtract equation 2 from equation 1 we get;

$(2y^2+7y-7)-(-4y+3)$

Now Applying distributive property for the sign we get;

$2y^2+7y-7+4y-3$

Now Arranging the like terms we get;

$2y2+7y-+4y-7-3\\\\2y^2+11y-10$

Hence the reduce form of the given equation is $2y^2+11y-10$ .

Adiya said that the first step to solving the quadratic equation x2 + 6 = 20x by completing the square was to divide 6 by 2, squ

vivado [14]

Adiya’s method is not correct. To form a perfect square trinomial, the constant must be isolated on one side of the equation. Also, the coefficient of the term with an exponent of 1 on the variable is used to find the constant in the perfect square trinomial. Adiya should first get the 20x term on the same side of the equation as x2. Then she would divide 20 by 2, square it, and add 100 to both sides.
