Step-by-step explanation:
C. The line to the left of x=0 has a slope of -1 and a y-intercept of 2. That portion of the function does not include x=0. The line to the right of x=0 has a slope of -3 and a y-intercept of 5. That portion of the function includes the case x=0.

D. The line to the left of x=-3 is y=-2; the line to the right of there is y=4. The function is not defined at x=-3.

In parallelogram EFGH, the measure of angle F is (3x − 10)° and the measure of angle G is (5x + 22)°. What is the measure of angle G?

127°
Answers
Answer: 127 degrees
Step-by-step explanation:
I hope this helps
E F
H G
I had to write it out the parallelogram so I could have a better visual.
F and G are consecutive angles in a parallelogram (not on opposite sides).
This means they add to be 180 degrees.
F+G=180
(3x-10)+(5x+22)=180
(3x+5x)+(-10+22)=180
8x +12=180
Subtract 12 on both sides:
8x =180-12
Simplify:
8x =168
Divide both sides by 8:
x =168/8
x =21
If x=21 and want the measurement of angle G, then
(5x+22)=(5*21+22)=127.
So angle G has measurement 127 degrees.
The the measure of angle G will be 127°. Then the correct option is D.
What is a parallelogram?It is a polygon with four sides. The total interior angle is 360 degrees. A parallelogram's opposite sides are parallel and equal.
In parallelogram, the sum of the two adjacent angle is 180 degrees.
In parallelogram EFGH, the measure of angle F is (3x − 10)° and the measure of angle G is (5x + 22)°.
The angle F and angle G are the adjacent angle.
The sum of angle F and angle G is 180°.
∠F + ∠G = 180°
3x - 10 + 5x + 22 = 180
8x = 168
x = 21
Then the the measure of angle G will be
∠G = (5x + 22)°
∠G = (5 × 21 + 22)°
∠G = (105 + 22)°
∠G = 127°
The the measure of angle G will be 127°.
Then the correct option is D.

Answer:
Sonya would need to serve 1500 meals
Step-by-step explanation:
425=15%(x)+200 or 425=.15(x)+200
solve for x

subtract 200 from both sides
225=.15x
divide both sides by .15 to isolate x

Answers
3=5(2)-1
3=10-1
3=9
Therefore, 2,3 is not a solution because 3 is never equal to 9.
Answer:
No, it is not
Step-by-step explanation:
You have to plug it in:
(x,y) = (2,3)
y=5x-1 is also 3=5(2)-1
3=10-1
3=9 is a false statement so it is not a solution.

Point A ( 5, 3) is reflected across the x-axis what is the coordinate of the image.
Answers
Answer:

Step-by-step explanation:
when you reflect across x axis the y changes symbols.
The Point A(5, 3) is reflected across the x-axis, then the coordinate of the image is (5, -3).
What is a reflection?A reflection is a type of transformation that involves flipping a shape, known as the preimage, over a line, known as the line of reflection, to produce a new shape (called the image). You can picture what would happen if you flipped the form over the line in order to graph a reflection.
Given:
The point A(5, 3) is reflected across the x-axis.
The reflection across the x-axis:
The rule for a reflection over the x-axis is,
(x, y) → (x, −y).
So, the image point,
(5, 3) → (5, −3)
Therefore, the image point is (5, −3).

Step-by-step explanation:

f = 59
g = 180 - 121
g = 59
solve for a:5(a+2)-3(2a-5)=39
Answers
5a + 10 - 6a + 15 = 39
Combine liked terms

-25 on both sides
-a = 14
a = -14
Checking if a = -14, substitute it back into the equation
5(a + 2) -3(2a - 5) = 39
5(-14 + 2) -3(2(-14) - 5)) = 39
5(-12) -3(-28 - 5) = 39
-60 -3(-33) = 39
-60 + 90 = 39

(a) (2, 3 ) , then
d = [tex]\sqrt{2^2+3^2}[/tex]

= [tex]\sqrt{13}[/tex] ≈ 3.6 units ( to 1 dec. place )
------------------------------------------------
(b) ( - 5, 7 ) , then
d = [tex]\sqrt{(-5)^2+7^2}[/tex]

(c) (- 1, 4 )
d = [tex]\sqrt{(-1)^2+4^2}[/tex]

Answers
Hope it helps. Pls mark as brainliest
The required slope of the line through the points (-6, 3) and (-7,-4) is m = 7.
Given that,
To determine the slope of the line through the points (-6, 3) and (-7,-4).
The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.
Here,
The slope of the line is given by,
m = (y₂ - y₁) / (x₂ - x₁)
Substitute the point in the above equation,
m = 3 + 4/ -6 + 7
m =7 / 1
m = 7
Thus, the required slope of the line through the points (-6, 3) and (-7,-4) is m = 7.

Why are the solutions to the proportions StartFraction 50 over x EndFraction = StartFraction 10 over 20 EndFraction and StartFraction 10 over 50 EndFraction = StartFraction 20 over x EndFraction the same? because both result in the equation 20 x = 500, which simplifies to x = 25 because both result in the equation 20 x = 500, which simplifies to x = 250 because both result in the equation 10 x = 1,000, which simplifies to x = 10 because both result in the equation 10 x = 1,000, which simplifies to x = 100
Answers
Given:
Two equations are
[tex]\dfrac{50}{x}=\dfrac{10}{20}[/tex]
[tex]\dfrac{10}{50}=\dfrac{20}{x}[/tex]
To find:
The reason for same solutions to the proportions.
Solution:
First equation is
[tex]\dfrac{50}{x}=\dfrac{10}{20}[/tex]
On cross multiplication, we get
[tex]50\times 20=10\times x[/tex]
[tex]1000=10x[/tex]
Divide both sides by 10.
[tex]\dfrac{1000}{10}=x[/tex]
[tex]100=x[/tex]
The second equation is
[tex]\dfrac{10}{50}=\dfrac{20}{x}[/tex]
On cross multiplication, we get
[tex]10\times x=50\times 20[/tex]
[tex]10x=1000[/tex]
Divide both sides by 10.
[tex]x=\dfrac{1000}{10}[/tex]
[tex]x=100[/tex]
Solutions to the proportions are same because both result in the equation 10 x = 1,000, which simplifies to x = 100.
