Answer:

Graph (2) is the answer.

Step-by-step explanation:

Rule to rotate a point (x,y) 90° clockwise about the origin

                    (x,y) ⇒ (y,-x)

Then translated 3 units up

                   (y,-x) ⇒ (y,-x + 3)

So rule is (x,y) ⇒ (y, -x+3)

Now we take all the points of the trapezoid

(0, -1) ⇒ (-1, 3)

(1.5, -2.5) ⇒ (-2.5, 1.5)

(1.5, -3.5) ⇒ (-3.5, 1.5)

(0, -3.5) ⇒ (-3.5, 3)

These coordinates match with the points in figure (2)

Therefore, Graph (2) is the answer.

Sidney skated for 1 1/10 hours last month and 8 7/10 hours this month. How many
olganol [36]

Answer:

the number of hours does sidney skate in all is 9.8 hours

Step-by-step explanation:

The computation of the number of hours does sidney skate in all is as follows:

= Last month + this month

= 1 \frac{1}{10} + 8 \frac{7}{10}\\\\= \frac{11}{10} + \frac{87}{10}\\\\= \frac{98}{10}

= 9.8 hours

Hence, the number of hours does sidney skate in all is 9.8 hours

Which of the sets of equations represent the two lines graphed?
Oksi-84 [34.3K]

Answer:

B) y = x + 2 and y = -x - 4

Step-by-step explanation:

Let the equation of a straight line with x-intercept 'a' and y-intercept 'b' be

\frac{x}{a}  +  \frac{y}{b}  = 1

The line with positive slope has x-intercept a=-2 and y-intercept b=2.

Its equation is:

\frac{x}{ - 2}  +  \frac{y}{2}  = 1

Multiply through by 2

- x + y = 2

Solve for y,

\boxed {y = x + 2}

For the line with a negative slope,

the x-intercept is a=-4 and the y-intercept is b=-4

Its equation is

\frac{x}{ - 4}  +  \frac{y}{ - 4}  = 1

Multiply through by -4

x + y =  - 4

Solve for y

\boxed {y =  - x - 4}
