The set

B = {{1, {2, 3}}, 4, {5, 6, 7}, 8}

consists of 4 elements:

• {1, {2, 3}}

• 4

• {5, 6, 7}

• 8

so the correct choices are 4, 8, and {1, {2, 3}}.

Line GH contains points G(–2, 6) and H(5, –3). What is the slope of ?

Anon25 [30]

Answer:

$\Huge\boxed{\mathsf{-\frac{9}{7} }}}$

Step-by-step explanation:

SLOPE FORMULA:

$\displaystyle \mathsf{\frac{Y_2-Y_1}{X_2-X_1}=\frac{RISE}{RUN} }$

Y2=(-3)

Y1=6

X2=5

X1=(-2)

Solve.

$\displaystyle \mathsf{\frac{(-3)-6}{5-(-2)}=\frac{(-3)-6}{5+2}= \frac{-9}{7}=\boxed{\mathsf{-\frac{9}{7}} }}$

The slope is -9/7.

Q3 What is the equation of a line that is parallel to the line that is given by the equation x = -4? y=x-4 X ox=- v 4 ova -X 4 X

Zinaida [17]

Answer:

The equation of the line parallel to the x-axis is y = k, where 'k' is any real number. For example, considering the equation of a line, y = 2, for any value of 'x' the value of 'y' is always equal to 2.

Y= 10x - 32 what is the x and y value of this equation

Marrrta [24]

Answer:

$y=10x-32 \\ \\ x=\frac{y}{10}+3.2$

Step-by-step explanation:

$y=10x-32$

Because that's the equation given.

To solve for x, isolate the variable and then divide by the coefficient.

$y=10x-32 \\ \\ 10x=y+32 \\ \\ x=\frac{y}{10}+\frac{32}{10} \\ \\ x=\frac{y}{10}+3.2$
