On a coordinate plane, a straight line and a parallelogram are shown. The straight line has a negative slope and has a formula o

f y = negative x. The parallelogram has points G (negative 2, negative 3), F (1, negative 3), E (negative 1, negative 5), and H (2, negative 5).
What are the coordinates of the image of vertex F after a reflection across the line y = –x?

(–1, –3)
(3, –1)
(1, 3)
(–3, 1)

Answer:

B. (3, -1)

Step-by-step explanation: I got a 100 on the test

The rule for a reflection across line y = -x: (x, y) → (-y, -x)

F(1, -3) → F'(3, -1)

What is the measure of an angle whose sine is√3/2 ? 60 45 30

dem82 [27]

ANSWER

The required angle is
$60 \degree$

EXPLANATION

Let the angle whose sine is
$\frac{ \sqrt{3} }{2}$
be
$x \degree$

Then

$\sin(x \degree) = \frac{ \sqrt{3} }{2}$

We take the inverse sign of both sides to obtain,

$x = \sin ^{ - 1} ( \frac{ \sqrt{3} }{2} )$

We use our scientific calculator to evaluate and obtain,

$x = 60 \degree$

What is the answer to this problem? 0.35 + 0.27 = ?

gavmur [86]

Have you never added 2-digit numbers?
35 +27 = (30 +20) +(5 +7) = 50 +12 = 62

35/100 +27/100 = (35 +27)/100 = 62/100
0.35 +0.27 = 0.62

The basic idea, taught in 3rd grade, is to line up the decimal points of the numbers, add enough zeros on the right to make the numbers all have the same number of digits to the right of the decimal point, then add in the usual way. The sum has the decimal point aligned with the rest of the numbers.

elena-14-01-66 [18.8K]

We are given that Jack and Jillian sell apples at a produce stand .

We are given that an expression which shows Jack's earning=2x-8

We have to find that first term what represent in the given expression

Jillian earns for each bag of apples she sells=$2

Let Jillian sold number of bags of apples =x

Then ,Jillian earn total at the end of the week =

Jack has earned $ 8 less than Jillian earn

Therefore, total earning of jack=

In the given expression the first term 2x represent the earning of Jillian.

A save percentage in lacrosse is found by dividing the number of saves by the number of shots faced. A lacrosse goalie saved 6 o

Crazy boy [7]

Answer:

Additional saves = <u>34 lacrosse.</u>

Step-by-step explanation:

The additional saves = s

Then , the number of saves becomes = 6+s

and, the number of shots faced = 13+s

Save percentage in lacrosse is found by dividing the number of saves by the number of shots faced that is

$\text{ percentage\ in\ lacrosse} =\frac{\text the \ number\ of \ saves}{\text the \ number of shots faced }$

$\text{ percentage\ in\ lacrosse} =\frac{6+s}{13+s }$

Given , the percentage of lacrosse = 0.850

${0.850 } =\frac{6+s}{13+s }$

${0.850 \times}({13+s })=6+s$

$11.05+0.850s=6+s$

$11.05-6=s-0.850s$

$5.05=0.15s$

$s=33.66$

Since, additional saves must be an integer so round it off to the nearest integer 34.

Thus, Additional saves = <u>34 lacrosse.</u>

What is the slope for (-2,3) (6,-1)

TiliK225 [7]

Answer:

Step-by-step explanation:

The slope of the line between two points can be found with the following equation:

$\frac{y_{2} - y_{1}}{x_{2} - x_{1}}$

Plugging in the points $(x_{1}, y_{1})$ and $(x_{2}, y_{2})$ from the problem statement, we get the following:

$\frac{-1 - 3}{6 - (-2)$

$\frac{-4}{8}$

$\frac{-1}{2}$
