Answer:

x=9

Step-by-step explanation:

every angle of a triangle added together equals 180. ill just show my work bc its hard to explain:

7x+2 + 4x+7 + 8x = 19x+9

19x+9 = 180

     -9     -9

19x = 171    (now divide by 19)

x=9

Answer:

all real numbers

Step-by-step explanation:

3x-8 = -x + 4(x-2)

distributive property:

3x - 8 = -x + 4x-8

Combine like terms:

(add 3x to both sides)

-8 = -8

That means that x can be any number, because in the end, x will be canceled out from the equation.

AllRealNumbers

The equation representing the function f(x) -

y = 4x - 8

We have a linear function f(x) as shown in the graph.

We have to determine the slope-intercept form of the equation representing this function.

The Slope - intercept form of the equation of a straight line is as follows -

y = mx + c

where -

m - slope of line

c - intercept of line on y - axis.

According to the question, we have -

c = - 8 = intercept of line on y - axes.

Intercepting coordinates on  y - axes = (0, -8).

Intercepting coordinates on x - axes = (2, 0).

Slope = m = [tex]\frac{-8-0}{-2 -0}[/tex] = 4

Therefore, the equation representing the function f(x) -

y = 4x - 8.

Answer:$9.24

Step-by-step explanation:

Answer:

Suzanne spent $4.29 on the apples

this is known because you need to add 1.32 three times then add .33 to it which will give you 3.96 + .33 = 4.29

Answer:

Lol hahahahahaha

Step-by-step explanation:

Sum of two angles that are supplementary = 180°

Then :-

[tex]3x - 2 + 2x+ 7 = 180[/tex]

[tex]5x + 5 = 180[/tex]

[tex]5x = 180 - 5[/tex]

[tex]5x = 180 - 5[/tex]

[tex]5x = 175[/tex]

[tex]x = \frac{175}{5} [/tex]

[tex]x = 35[/tex]

Which means :-

The measure of the larger angle :-

= 35 × 3 - 2

= 105 - 2

= 103°

The measure of the smaller angle :-

= 2 × 35 + 7

= 70 + 7

Therefore , the value of x = 35 and the measure of the smaller angle = 77° .

Answer:

The plastic model is 50 meters tall

Step-by-step explanation:

Here, we want to know how tall is the plastic model

In the plastic model 10 m represents 65 meters

then x meters plastic = 325 m real

10 * 325 = 65 * x

3250 = 65x

x = 3250/65

x = 50 meters

The recursive formula is [tex]a_n\\[/tex] = 6n - 4.

Any term of a series can be defined by its preceding term in a recursive formula (s).

A recursive formula consists of two parts: a declaration of the first term and a declaration of the formula connecting the succeeding terms.

For example: The recursive formula of an arithmetic sequence is,

an = an-1 + d.

Given:

2, 8, 14, 20

The above data shows Arithmetic Progression series.

a = 2

d = 8-2

d= 6

So, using Arithmetic Progression

[tex]a_n[/tex] = a+ (n- 1) d

[tex]a_n\\[/tex] = 2+ (n- 1)6

[tex]a_n\\[/tex] = 2+ 6n - 6

[tex]a_n\\[/tex] = 6n - 4

Hence, the recursive formula is [tex]a_n\\[/tex] = 6n - 4.

Step-by-step explanation:

Step-by-step explanation:

Answer: 12

Step-by-step explanation: It’s on the same y axis and -4 to 8 is going to the right on a graph.

Answer:

1) 2<x<10 (the first choice)

2) 17<x<40 (the first choice)

3) x<-1 or x>2 (the second choice)

Step-by-step explanation:

1) 2<x<10...this is another way of representing x<10 and x>2 in an "and" inequality. If you look at 2<x<10 from left to right, it says 2 is less than x and x is less than 10.

2) 17<x<40...this represents x>17 and x<40 in an "and" inequality as well. If you look at 17<x<40, it reads 17 is less than or equal to x and x is less than 40.

3) x<-1 or x>2...the signs are greater than or equal to because the dots are closed on the number line. Also, this is not an "and" inequality. This is actually an "or" inequality. You can mainly tell because the lines are shaded opposite ways and do not intersect.

Answer:

x=55

Step-by-step explanation:

you have to add the three angles to get 180 first. 180- 21-34=125.

then take the missing angle inside the triangle (125) and subtract by 180.

180-125=55

Answer:

x = 55

Step-by-step explanation:

We know that triangles add up to 180 degrees, so let's start with that. Keep in mind that "y" will be the third degree of the triangle.

21+34+y = 180

55+y = 180

y = 125

Okay, now we know that the third degree is 125. Also, the line that 125 and x are on is a straight line. All straight lines are 180 degrees. Subtract 180 and 125 to get your answer.

180-125 = 55

So your final answer will be x=55, hope this helped!
