Answer:

x=-7/2, x=4/3

Step-by-step explanation:

$6x^2+13x-28=0$

Multiply 6 and -28 to get -168

Find 2 numbers that multiply to 168 but add to 13

They are 21 & -8

Rewrite the equation into:

$6x^2+21x-8x-28=0$

Factor

$3x(2x+7)-4(2x+7)=0$

(3x-4)(2x+7)=0

3x=4

x=4/3

2x=-7

x=-7/2

Answer:

(2, 2) states x=2 and y=2

Considering the inequality:

$y\leq 4x-6$

Is y less than or equal to 2 when x = 2?

$2\leq 4(2)-6\\2\leq 8-6\\2\leq 2\\$

Yes, (2, 2) is a solution for the inequality.

True or false "No rectangle is a rhombus?"

alukav5142 [94]

False.
Rhombuses may be rectangles, as long as the shape is a square. Every square is a rhombus if all its angles equal 90 degrees.

$\frac{1}{6}$ or 0.167 pounds more butter was used than sugar

Solution:

Given that, Desmond's Desserts made a batch of fresh scones with 2/3 of a pound of butter and 1/2 of a pound of sugar

To find: Amount of butter used than sugar

From given information,

$\text{Butter used} = \frac{2}{3} \text{ pound }$

$\text{Sugar used } = \frac{1}{2} \text{ pound }$

To find how much butter is used than sugar, find the difference between them

$Difference = Butter\ used - Sugar\ used$

$Difference = \frac{2}{3} - \frac{1}{2}\\\\Difference = \frac{2 \times 2-1 \times 3}{3 \times 2}\\\\Difference =\frac{4-3}{6}\\\\Difference =\frac{1}{6} = 0.167\\\\$

Thus $\frac{1}{6}$ or 0.167 pounds more butter was used than sugar
