Answer:

34 degrees, 68 degrees, 78 degrees

Step-by-step explanation:

All angles in a triangle must add up to 180 degrees.

so

x + 2x + 2x + 10 = 180

(group together all the xs)

5x + 10 = 180

(subtract 10 from both sides)

5x = 170

(divide both sides by 5)

x = 170/5 = 34

Angle 1 = x

x = 34

Angle 1 = 34 degrees

Angle 2 = 2x

x = 34

(multiply both sides by 2)

2x = 68

Angle 2 = 68 degrees

Angle 3 = 2x + 10

x = 34

(multiply both sides by 2)

2x = 68

(add 10 to both sides)

2x + 10 = 68 + 10 = 78

Angle 3 = 78 degrees

CHECK YOUR ANSWERS:

All angles in a triangle must add up to be 180 degrees.

so

34 + 68 + 78 should equal 180

34 + 68 + 78 = 180 degrees

Hope this helps :)

Answer:

Step-by-step explanation:

sum of angles of a triangle= 180°

x+2x+2x+10=180

5x+10=180

5x=170

x=170/5

x=34

.:

x=34°

2x=34×2=68°

2x+10=2×34+10=68+10=78°

Jose has saved $75 to take tutoring classes. He must pay a registration fee of $15 and then an additional $6 for each class.
bonufazy [111]

Answer:

15+6x=75

Step-by-step explanation:

15 is the starting fee and it is 6$ per class so it would be 6x+15=75

What is the scale factor from ABC to DEF?​
ollegr [7]

Answer:

C

Step-by-step explanation:

The scale factor is the ratio of corresponding sides, image to original, so

scale factor = \frac{EF}{BC} = \frac{11}{66} = \frac{1}{6} → C

Please answer quickly I will give brainliest- Kelsey has a list of possible functions. Pick one of the g(x) functions below and
Marizza181 [45]

Answer:

1. Behavior

The g(x) is large and positive when x is large and positive;

The g(x) is large and negative when x is large and negative.

2. y-intercept= -18

3. The zeros are: -3, -2 and 3

Step-by-step explanation:

1. End behavior:

To find this you have to know the leading coefficient of the variable with the highest degree, and whether the degree is even or odd.  

(x + 3) = x positive, coefficient 1

(x + 2) = x positive, coefficient 1

(x − 3)=  x positive, coefficient 1

The coefficient is 1*1*1= 1 = positive

There are 3 x, so it will be x^3= odd

The behavior for odd and positive will be:

g(x) is + ∞ when x=>+∞

g(x) is -∞ when x=>-∞

or

The g(x) is large and positive when x is large and positive;

The g(x) is large and negative when x is large and negative.

2. Y-intercept

The y-intercept is the value of y when the graph touches the y-axis. The y-axis is located at x=0, so to find the y-intercept you need to put x=0 on the graph function. Some graphs can have two y-intercepts but the graph on the question only has one. The calculation will be:

y-intercept = g(0)= (0+3)(0+2)(0-3)

y-intercept = 3*2*-3

y-intercept= -18

3. Zeros

The zeros mean the value of x that will result as g(x) as zero. At this coordinate, the graph will touch the x-axis since g(0) is located on the x-axis. That is why this coordinate also called an x-intercept. The function is expressed as the product of three things. If any of them is 0, then the result will be 0. So we have 3 zeros

x_{1}+3=0

x_{1}=-3

x_{2} +2=0

x_{2}=-2

x_{3}-3=0

x_{3}=3

The zeros are: -3, -2 and 3
