Rhombus PQRS with vertices P(-1,-3), Q(3,-4), R(4,-8) and S(0,-7)
A)Translation along the vector (4,10)
B) 90 (degrees) counterclockwise rotation about the origin.
Answers
P’(3, 7), Q’(7, 6), R’(8, 2), S’(4, 3)
B) Rotation is tricky. 90 degrees will swap x with y and counterclockwise will reverse the sign of the new x
P’(-7, 3), Q’(-6, 7), R’(-2, 8), S’(-3, 4)
A clockwise rotation would swap the values and reverse the sign of the new y values
Half turn rotation would just reverse the values of all the coordinates

Find the indicated values by using the table.
X= g(x)=2x+1
Answers
g(10) = 21
g(0) = 1
g(10) = 21
g(22) = 45
g(28) = 57
g(16) = 33
Step-by-step explanation:
g(x) = 2x + 1
Then in order to find g(10), replace x over 10
g(10) = 2(10) + 1
g(10) = 20 + 1
g(10) = 21
so g(10) = 21

Has a slope of 4 and passes through (-2, 4)
Answers
Answer:
y = 4x + 12
Step-by-step explanation:
y = mx + b
m = slope = 4
substitute the point (-2, 4) as (x, y)
4 = 4(-2) + b
4 = -8 + b
12 = b
Hope this helps! Pls give brainliest!
The equation of line is y= 2x+ 8.
what is slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx
where, m is the slope
Given:
Slope= 2
and, Passes through (-2, 4)
So, using the slope- intercept form is
y= mx+ b
4 = 2(-2)+ b
4 = -4 + b
b=8
And, the equation of line is
y= mx+ b
y= 2x + 8
Hence, the equation of line is y= 2x+ 8.

-1/3x-1/6=2/9 solution
Answers
Answer:
-1 1/6
Step-by-step explanation:
Use a common denominator first to convert all the fractions so they can be easily added or subtracted.
Common denominator is 18 since 3, 6, and 9 can all evenly divide into 18
1/3 = 6/18
1/6 = 3/18
2/9 = 4/18
So now you have
-6/18x - 3/18 = 4/18
add 6/18x to both sides so you can make the number with the variable positive
6/18x - 6/18x - 3/18 = 4/18 + 6/18x simplifies to - 3/18 = 4/18 + 6/18x
subtract 4/18 from both sides
- 3/18 - 4/18 = 4/18 - 4/18 + 6/18x simplifies to - 7/18 = 6/18x
Divide both sides by 6/18 so x is alone on the one side
( - 7/18) / ( 6/18) = ( 6/18x) / ( 6/18) simplifies to ( - 7/18) / ( 6/18) = x
When you divide a fraction by a fraction, the bottom fraction gets flipped over then you multiply the two new fractions straight across
so the new equation looks like this
- 7/18 times 18/6 and you multiply -7 x 18 = -126 and the bottom is 18 times 6 = 108 you now have -126/108
x = -126/108 which simplifies to - 1 18/108 which can still be simplified more to -1 1 / 6 since 108 can be divided by 18 that gives you 6.

A pillar is fixed at one of the corners of a square meadow. The length of each edge of the meadow is 30m and the angle of elevation of the top of the pillar from the opposite comer is found 60°. Find the height of the pillar.
(A) 93.49 m (B) 83.48 m (C) 69.93 m (D) 73.48m
Answers
Answer:
D. 73.48 m.
Step-by-step explanation:
The diagonal distance across the meadow
= √(30^2+30^2)
= √1800
tan 60 = h / length of the diagonal (where h = height of the pillar).
h = √1800 * tan 60
= 73.48 m
The required height of the pillar if length of each edge of the meadow is 30m and the angle of elevation of 60 degrees is 73.48m
Angle of elevation and depressionThe angle situated below the pillar is known as the angle of elevation
Determine the diagonal distanceThe diagonal distance across the meadow is calculated using the Pythagoras theorem:
l = √(30^2+30^2)
l = √1800
tan 60 = h/l
where h = height of the pillar
h = √1800 * tan 60
h = 73.48 m
Hence the required height of the pillar if length of each edge of the meadow is 30m and the angle of elevation of the top of the pillar from the opposite comer of 60 degrees is 73.48m
