Answer:

angle x is 60 degrees

Step-by-step explanation:

Complementary angles means the sum of the angles is 90 degrees, so if angle x decreases, angle y must increase.

Angle A and angle C are vertical angles. If m∠A=(3x+7)∘ and m∠C=(x+53)∘, what is the value of x

777dan777 [17]

Since it is a given that the angles are vertical, then that means they have to be congruent or = to each other so we can now set up an equation:

3x+7=x+53

Now we need to get the variable alone on one side so subtract 7 from the left (remember what you do, you must do to both sides)

3x=46

Now we can divide by three to get x alone

x=15.333333333 or rounded to 15.33

PLS HELP ASAP THANKS ILL GIVE BRAINLKEST PLS THANKS PLS

worty [1.4K]

Answer:

(0, -3)

explanation:

original coordinates of C: (0, -7)

If reflected over y axis, there will be additive inverse in x unit

use the formula: (x,y) → (−x, y)

new coordinates: (0, -7)

Then if translated vertically, there will be change in y axis:

(0, -7+4) → (0, -3)

Morten Andersen played in NFL for 25 years write and solve an equation to find how many points he averaged each year

soldi70 [24.7K]

Answer:

$r =\frac{2437points}{25 years} =97.45 \frac{points}{year}$

So then we have that Morten Andersen scored on average 97.45 points per year in his career.

Step-by-step explanation:

Assuming the following table on the figure attached.

We see that the career points for Morten Andersen was 2437. That include all the points over alll the years the he played in the NFL.

Since the total years played by Morten Andersen was 25 we can write the following equation:

$25 r =2437$

Where $r$ represent the rate of points average per year.

If we solve for r from the last equation we can divide both sides of the equation and we got:

$r =\frac{2437points}{25 years} =97.45 \frac{points}{year}$

So then we have that Morten Andersen scored on average 97.45 points per year in his career.

Use the table to write a linear function that relates y to x.

blsea [12.9K]

Answer:

y = - $\frac{2}{3}$ x

Step-by-step explanation:

the equation of a linear function in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

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

with (x₁, y₁ ) = (- 8, 2) and (x₂, y₂ ) = (1, - 4) ← 2 ordered pairs from the table

m = $\frac{-4-2}{1-(-8)}$ = $\frac{-6}{1+8}$ = $\frac{-6}{9}$ = - $\frac{2}{3}$

the ordered pair (0, 0 ) indicates the line crosses through the origin, then

c = 0

y = - $\frac{2}{3}$ x + 0 , that is

y = - $\frac{2}{3}$ x ← equation of linear function
