Answer:
r(180°,0) is a rotation of 180° degrees over the origin.
Notice that this rotation moves our figure to the opposite quadrant (so a translation of two quadrants).
Then this is equivalent to:
A reflection over the x-axis followed by a reflection over the y-axis.
Or.
A reflection over the y-axis followed by a reflection over the x-axis.
There is another possible reflection, but it depends on where is our figure.
If the figure is in the first or third quadrant, a reflection over the line y = -x is equivalent to the rotation.
If the figure is in the second or third quadrant, then the reflection over the line y = x is equivalent to the rotation.
We can combine those two and write:
A reflection over the line y = (-1)^n*x.
Where n is the number associated with the quadrant where the figure is in.
for the equation x + y = 3. How many possible values for x are there if x and y are both whole numbers?
A.2
B.3
C.4
Answer:
A
Step-by-step explanation:
Because it is 2+1 and 3+0, those are the only solution, therefore A is correct
======================================================
Explanation:
The set of whole numbers is {0, 1, 2, 3, ...}
So we include 0 and any positive number that doesn't have decimal or fractional components to it. Negative values are not included.
If we plug in x = 0, then x+y = 3 solves to y = 3If we plug in x = 1, then x+y = 3 solves to y = 2If we try x = 2, then x+y = 3 solves to y = 1Lastly, x = 3 leads to y = 0Whatever you pick for x, the y value must add to it to get 3. Both x and y must be numbers from the set of whole numbers.
There are four cases shown in the bullet points above, so we have four different solutions. We can't move onto x = 4 because the y solution would be y = -1, but -1 is not in the set of whole numbers.
Jackie worked 7.5 hours yesterday. If she earns $8.05 an hour, how much did she earn yesterday?
Answer:
$8.05(7.5)= $60.375
Step-by-step explanation:
Just multiply the two together.
I think you would round to $60.38

Answer:
(2.666667, -2)
Step-by-step explanation:
y+2 = -3x+12
(-4 times -3 = positive 12)
subtract 2 from both sides
y=-3x-10
-2=-3x-10
add ten to both sides

Write the coordinate of A’ after A (5,3) got reflected over the x-axis.
Answer:
A'(5, -3)
Step-by-step explanation:
Reflection over the x-axis changes the sign of the y-coordinate:
(x, y) ⇒ (x, -y)
A(5, 3) ⇒ A'(5, -3)
What is an equation of the line that is parallel to the one shown and passes through (6, −5)?
A. y=−23x−1
B. y=32x−4
C. y=23x+1
D. y=−32x+4
Answer:
D is the answer
The equation in slope-intercept form, of the line that passes through (6, -5) and is parallel to the line given is: D. [tex]\mathbf{y = -\frac{3}{2} x + 4}[/tex]
Recall:
Slope of two lines that are parallel to each other will always be the same value.Slope = rise/runFrom the graph shown, the slope (m) of the line is [tex]-\frac{3}{2}[/tex].
Thus, the line that passes through (6, -5) and is parallel to the line in the graph will have the same slope of [tex]-\frac{3}{2}[/tex].
Write the equation in point-slope form by substituting (a, b) = (6, -5) and m = -3/2 into y - b = m(x - a).
Thus:[tex]y - (-5) = -\frac{3}{2} (x - 6)\\\\y +5 = -\frac{3}{2} (x - 6)[/tex]
Rewrite in point-slope form as y = mx + b
[tex]y +5 = -\frac{3}{2} (x - 6)\\\\y + 5 = -\frac{3}{2} x + 9\\\\y = -\frac{3}{2} x + 9 - 5\\\\\mathbf{y = -\frac{3}{2} x + 4}[/tex]
Therefore, the equation in slope-intercept form, of the line that passes through (6, -5) and is parallel to the line given is: D. [tex]\mathbf{y = -\frac{3}{2} x + 4}[/tex]Learn more here:

I am having a lot of struggles please help
Answer: x = 23
∠DBC = 23°
∠ABC = 157°
Step-by-step explanation: A straight line is 180°, which means that ∠DBC and ∠ABC must equal 180°.
180 - 19 = 161
23 × 6 = 138
138 + 23 = 161
If x = 23°, then ∠DBC is 23°.
For ∠ABC, (6(x) + 19°
6(23) + 19°
6 × 23 = 138
138 + 19 = 157
∠ABC = 157°
