Answer:

The image point of (-7, 1) after reflection across the y-axis is:

Step-by-step explanation:

When a point P(x, y) is reflected across the y-axis, we reverse the sign of the x-coordinate while the y-coordinate remains the same.  

Thus,  

The rule to reflect a point across the y-axis is:  

P(x, y) → P'(-x, y)

In our case, we are given the point (-7, 1)

Let say the point is A(-7, 1).

Thus, using the rule to reflect a point across the y-axis is:  

P(x, y) → P'(-x, y)

A(-7, 1) → A'(-(-7), 1) → A'(7, 1)

Therefore, the image point of (-7, 1) after reflection across the y-axis is:

Answer:

The blank in the equation is 1.

x = 7 and the vertical angles measure out to 64 degrees.

Step-by-step explanation:

When solving for x, you always want to keep the variables on one side. So you'll subtract 9x from both sides. That gives you 1=3x-20. Then you'll add 20 to both sides. This gives you 21=3x. After you'll divide by 3 on both sides. This gives you 7=x.

Now you'll plug in 7 for x. This gives you 12*7-20=9*7+1. First, you'll multiply which gives you 84-20=63+1. Add and you'll get 64 on both sides.

Answer:

Step-by-step explanation

x+38=2(x+14)

The man is 38 and daughter is 14. They both will age in same years (x).

So, in how many years(x) will they both age until man is equal(=) to 2 times his daughters age?

x+ 38=2(x+14)

x+38=2x+ 28

10= x

In 10 years, the man will be 2twice as old as his daughter.

Answer:

(x-9)°+6x=180°[by linear pair]

7x-9=180°

7x=180°+9

7x=189°

x=189/7

x=27

(x-9)°=27-9=18°

(6x)°=6×27=162°

The angle measures are 18 degrees and 162 degrees.

An angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle.

In the given figure ∠1=x-9 and ∠2=6x

The sum of ∠1 and ∠2 is 180 degrees by linear pair.

∠1 +∠2 =180

x-9+6x=180

Add the x variable terms

5x-9=180

Add 9 on both sides

5x=189

Divide both sides by 5

x=27

Now substitute value of x in angle 1 and angle 2.

∠1=x-9=27-9=18 degrees

∠2=6x=6(27)=162 degrees.

Hence, the angle measures are 18 degrees and 162 degrees.

Answer:

A rice cooker, also known as a rice steamer, is a popular small appliance that works like a slow cooker by using moist heat to cook food while trapping the flavors in the pot until it’s ready to enjoy. Modern rice pressure cookers significantly reduce rice-making time and often feature a warming setting so you can be flexible with meal times.

Answer:

60

Step-by-step explanation:

The whole thing is 180 so if you subtract 180 from 120 you get 60.

Answer:

60 degrees since a straight line is 180 degrees

Step-by-step explanation:

Since part of it is 120 degrees the other part must be 60 because 120 + 60 = 180

Answer:

The zeroes of [tex]g(x)=4x^4+4x^3-11x^2-12x-3[/tex] are [tex]-\sqrt{3}, -\frac{1}{2}, \sqrt{3}[/tex], or approximately [tex]-1.732, -0.500, 1.732[/tex].

Step-by-step explanation:

By inputting the function in a graphical calculator we can see that the roots of the graph of [tex]g[/tex] are about [tex]x=-1.732, x = 0.500, x = 1.732[/tex] (make sure you click on the points of interests).

Notice that [tex]g(x) = 4x^4+4x^3-11x^2-12x-3 = (2x-1)^2(x^2-3).[/tex] So the roots can be calculated with [tex](2x-1)^2 = 0 \vee x^2 - 3 = 0[/tex], yielding [tex]x = -\frac{1}{2} \vee x = \pm\sqrt{3}[/tex].
