$\huge\textsf{Hey there!}$

$\large\textsf{8(-3) + (-1)}$

$\large\textsf{= 8(-3) - 1}$

$\large\textsf{8(-3) = \boxed{\large\textsf{\bf -24}}}$

$\large\textsf{-24 - 1}$

$\large\textsf{= \underline{\bf -25}}$

$\boxed{\boxed{\large\textsf{Answer: \huge \bf -25}}}\huge\checkmark$

Match the solution set of each of the following inequalities with its graph.

8090 [49]

Answer:

Step-by-step explanation:

From the picture attached,

Number line Inequality

1). Arrow starting with a solid point from x = -2 x ≤ -2

directing towards negative numbers of x 2).Arrow starting with a hollow circle from x = 2 x >2

directing towards positive numbers of x

3). Arrow starting with a hollow circle from x = 2 x < 2 ⇒ x - 2 < 0

directing towards negative numbers of x

4). Arrow starting with a solid circle from x = 2 x ≥ 2 Or 2 ≤ x

directing towards positive numbers of x

5). Arrow starting with a hollow circle from x = -2 x > -2

directing towards positive numbers of x

Please help me!!!!!!!

Helen [10]

First we will find the value of x.

To find the value of x we can add angle Q and angle O and set them equal to 180 and solve for x.

We will be setting them equal to 180 since the opposite angles of an inscribed quadrilateral are supplementary.

angle Q + angle O = 180
6x - 5 + x + 17 = 180
7x +12 = 180
7x = 168
x = 24

Now we can use 24 for x and find the value of angle QRO

angle QRO = 2x + 19
angle QRO = 2(24) + 19
angle QRO = 48 + 19
angle QRO = 67

So the answer choice B is the right answer.

Hope this helps :)<span />

Solve the system of equations.<br> – 3y + 5x = 26<br> - 2 - 5x = -16

mylen [45]

Answer:

$y=-4,\:x=\frac{14}{5}$

Step-by-step explanation:

$\begin{bmatrix}-3y+5x=26\\ -2-5x=-16\end{bmatrix}$

Isolate x for -2-5x=-16:

$x=\frac{14}{5}$

$\mathrm{Substitute\:}x=\frac{14}{5}$

$\begin{bmatrix}-3y+5\cdot \frac{14}{5}=26\end{bmatrix}$

$Simplify$

$\begin{bmatrix}-3y+14=26\end{bmatrix}$

Isolate y for -3y+14=26:

$y=-4$

$\mathrm{The\:solutions\:to\:the\:system\:of\:equations\:are:}$

$y=-4,\:x=\frac{14}{5}$

An urn contains three red balls and four blue balls. Draw two balls at random from the urn, without replacement. Compute the exp

mezya [45]

Step-by-step explanation:

in total we have 3+4 = 7 balls.

when we draw the first ball, the probability to draw a red ball is 3/7, and a blue ball 4/7.

when we draw the second ball, we have now only 6 balls in total.

the probabilty to draw a red back now depends also on the result of the first draw.

if the first ball was already red, then we have only a chance now of 2 out of 6.

if the first ball was blue, then we have now a chance of 3 out of 6.

so, the probably to draw at least 1 red ball in 2 draws is the probability of drawing one on the first draw plus the probability of drawing one on the second :

1 - probability to see 2 blue balls

1 - 4/7 × 3/6 = 1 - 12/42 = 30/42 = 0.714285714...

the expected number of red balls in 2 draws is

1 red in first red in first red in second

but not second and second but not first

1×(3/7 × 4/6) + 2×(3/7 × 2/6) + 1×(4/7 × 3/6) = 12/42 + 12/42 + 12/42 = 36/42 = 6/7 = 0.857142857 ≈ 0.8571
