The easy answer: If, say, B is the zero matrix, i.e.

$B=\begin{bmatrix}0&0\\0&0\end{bmatrix}$

then

$2A=\begin{bmatrix}5&0\\-1&2\end{bmatrix}\implies A=\begin{bmatrix}\dfrac52&0\\\\-\dfrac12&1\end{bmatrix}$

The vertices of a triangle are P(–8, 6), Q(1, –3), and R(–6, –3). Name the vertices of

xz_007 [3.2K]

The refrection of a point or set of points across the line y = x will result in a point or set of points whose coordinates are the interchange of the x-value and the y-value of the original point or set of points.

Given that the vertices of a triangle are P(-8, 6), Q(1, -3) and R(-6, -3), the vertices of the triangle formed by the refrection Ry=x<span>(ΔPQR) are P'(6, -8), Q'(-3, 1) and R'(-3, -6).</span>

What is the slope and the y-intercept of the line on the graph below?

miss Akunina [59]

Well, since we do not know the line, the basic slope formula is Y = mX + B
So look at the line and see where is crosses the y axis (the vertical) and that is your B in the formula or the "Y-intercept" as an example I will used the number 1. Then on your line pick two points, I will use the points (4,4) and (1,2) as an example. To find your slope take the Ys in those points (the second number) and subtract them 4 - 2 = 2. Then subtract the Xs (the first numbers) 4 - 1 = 3. Lastly, take the 2 and divide it by the 3 (yes it can be a fraction) and that is your slope. So the entire answer with my examples would be Y = $\frac{2}{3}$ x + 1 with 1 being my y-intercept and 2/3 being my slope

I would like to know what 1.34 as a fraction in simplest form would be

Paha777 [63]

$1.34 = 1 \dfrac{34}{100} = 1 \dfrac{34 \div 2}{100 \div 2} = 1 \dfrac{17}{50}$

-------- Edited to include more explanation --------------

1.34 = 1 whole 34 hundredth

$\text { 1 whole 34 hundredth written as a fraction =} 1 \dfrac{34}{100}$

Then we simplified it by dividing the numerator and the denominator by 2:

$1 \dfrac{34}{100} = 1 \dfrac{34 \div 2}{100 \div 2}$

34 divided by 2 will give us 17 and 100 divided by 2 will give us 50:

$1 \dfrac{34 \div 2}{100 \div 2} = 1 \dfrac{17}{50}$

Can someone please help me? And it says “Solve each equation. Then, prove that your answer solves the original equation?

Viefleur [7K]

Step-by-step explanation:

We need to solve each equation.

a. 6c = 30

c = 30/6 = 5

2d-6=12

Adding 6 both sides

2d-6+6=12+6

2d = 18

d = 9

$\dfrac{x}{3}+9=2\\\\\dfrac{x}{3}=-7\\\\x=-21$

50=14+3m

50-14=3m

36=3m

m = 12

Hence, this is the required solution.
