MariettaO [177]

Answer:

B. -1.5x − 3.5y = -31.5

Step-by-step explanation:

You forgot to provide the reference image which is essential to answer the question, but I managed to find it... and attach it to my answer.

In the given equation for AB, if we place the y term on the left and x term on the right, we see the slope of that line is 7/3 (y = (7x - 21.5)/3 ==> 7/3x).

We see on the image that the line PQ is perpendicular to AB. That means that its slope is -3/7.

If we quickly check the slopes of each of the possible answers...

A. -3x + 4y = 3 ----> 4y = 3x - 3 ==> y = (3x-3)/4 => slope = 3/4

Not what we're looking for.

B. -1.5x - 3.5y = -31.5 ==> 3.5y = -1.5x + 31 ===> y = (-1.5x +31)/3.5

that gives us a slope of -1.5/3.5... We can simplify it... -3(0.5)/7(0.5) = -3/7

Exactly as predicted.

Since we have the point P (7,6), we can enter it in the equation to verify:

-1.5x - 3.5y = -31.5

-1.5 (7) - 3.5 (6) = -10.5 - 21 = -31.5 --- Verified

C. 2x + y = 20 ==> y = 20 - 2x ===> slope is -2, not what we want.

D. -2.25x + y = -9.75 ==> y = 2.25x - 9.75 ==> slop is 2.25 cannot be it.

Find all solutions by transforming the system to reduced echelon form and back substituting. (If there are an infinite number of

Zolol [24]

Answer:

The system has infinite solutions described in the set $\{(x_1,x_2,x_3)=(6+s1, -10-2s1,s1): s1\in\mathbb{R}\}$

Step-by-step explanation:

The augmented matrix of the system is $\left[\begin{array}{cccc}-1&-1&-1&4\\2&1&0&2\end{array}\right]$ .

We apply row operations:

1. We add the first row to the second row twice and obtain the matrix $\left[\begin{array}{cccc}-1&-1&-1&4\\0&-1&-2&10\end{array}\right]$

2. multiply by -1 the rows of the previous matrix and obtain the matrix $\left[\begin{array}{cccc}1&1&1&-4\\0&1&2&-10\end{array}\right]$ that is the reduced echelon form of the matrix associated to the system.

Now we aply backward substitution:

1. Observe that the reduced echelon form has a free variable, then the system has infinite solutions.

$x_2+2x_3=-10\\x_2=-10-2x_3$

$x_1+x_2+x_3=-4\\x_1-10-2x_3+x_3=-4\\x_1-x_3=-4+10\\x_1=6+x_3$ .

Then the set of solutions is $\{(x_1,x_2,x_3)=(6+s1, -10-2s1,s1): s1\in\mathbb{R}\}$

60.8 is what percent of 32

Anna71 [15]

60.8 is 190% of 32

Divide 60.8 over 32:
$\frac{60.8}{32} = 1.9$

Convert the decimal into a percentage by dividing it over 100:
$1.9 \times 100 = 190$

What is the equation of the parabola?

Morgarella [4.7K]

Step-by-step explanation:

Show Solution. Start by writing the equation of the parabola in standard form. The standard form that applies to the given equation is (x−h)2=4p(y−k) ( x − h ) 2 = 4 p ( y − k ) . Thus, the axis of symmetry is parallel to the y-axis.
