You have only listed one value for 'x'.

If 'x' is 2/3, then 6x is (6 times 2/3). That's 12/3 or 4 .

$6x=6\times x=6\cdot x\\\\substitute\ x=\frac{2}{3}\ to\ 6x:\\\\6\times\frac{2}{3}=\frac{\not6^2}{1}\times\frac{2}{\not3_1}=2\times2=4$

Answer:

yes, about 2.05 inches

Step-by-step explanation:

The Pythagorean theorem can be used to find the width of the TV.

w^2 +h^2 = d^2

w = √(d^2 -h^2)

w = √(42^2 -18^2) = √1440 = 12√10

w ≈ 37.95 . . . inches

This dimension is less than 40 inches by a margin of ...

40 -37.95 = 2.05 . . . inches

The TV will fit, with 2.05 inches of space remaining.

Select the quadratic that has roots x = 8 and x = -5.

Mars2501 [29]

$\text{ The roots are}~ \alpha = 8~ \text{and}~ \beta = -5\\\\\text{Equation for the given roots,}\\\\x^2 -(\alpha +\beta )x +\alpha \beta = 0\\\\\implies x^2 -(8-5)x + 8(-5)=0\\\\\implies x^2 -3x -40=0\\\\\text{Hence, the answer is option B}$

Y = 3 X intercept : ________ Y intercept : ________ Slope: ________

erik [133]

Y = 3 will be a straight, horizontal line on 3. It will only touch the y-axis since there's no x. So, the X-Intercept doesn't exist, the Y-Intercept will be (0,3), and the slope of the line is 0.
