Answer:

m∠8 = 49°

Step-by-step explanation:

∠7 and ∠8 are same-side interior angles.

Remember, same-side interior angles are supplementary. This means that the sum of the angles is 180°.

Let's use the variable 'x' to represent the unknown measure of angle ∠8.

[tex]131 +x=180[/tex]

[tex]131-131=0[/tex] (cancels itself out)

[tex]180-131=49[/tex]

[tex]x=49[/tex]

Therefore, the measure of ∠8 is 49°.

Answer:

d = 164

Step-by-step explanation:

- To find the distance between two points, we have to plug the values into the distance formula:

d = √(x2 - x1)² + (y2 - y1)²

d = √(-156 - 4)² + [-38 - (-2)]

d = √(-160)² + (-36)²

d = √(25600) + (1296)

d = √26896

d = 164

Answer:

[tex]2 x ^{3} + 8x - 5[/tex]

Step-by-step explanation:

(h • g) (-5)

first we can isolate the first part

(x^2 +4) • (2x) = 2x^3 + 8x

then we just add the -5

2x^3 + 8x - 5

Answer:

5

Step-by-step explanation:

In the slope- intercept form of y= mx +b, m is the slope and b is the y- intercept.

Let's find the slope using the formula below:

[tex]\boxed{slope = \frac{y1 - y2}{x1 -x 2} }[/tex]

[tex]m = \frac{3 - ( - 3)}{1 - 4} [/tex]

[tex] m = \frac{3 + 3}{ - 3} [/tex]

[tex]m = \frac{6}{ - 3} [/tex]

m= -2

Substitute m= -2 into the equation:

y= -2x +b

To find the value of b, substitute a pair of coordinates into the equation:

When x= 1, y= 3,

3= -2(1) +b

3= -2 +b

b= 3 +2 (+2 on both sides)

b= 5

Thus, the 4th option is correct.

Hello there!

Given the sequence:

[tex] \displaystyle \large{ 1, - 3,9, - 27,...}[/tex]

The question reveals it to be geometric sequence since it has common ratio.

Geometric Sequence / Ratio Formula

[tex] \displaystyle \large{r = \frac{a_{n + 1}}{a_n} }[/tex]

Define 'r' as common ratio.

First, let's check the common ratio by using the formula above.

Ratio Check

[tex] \displaystyle \large{r = \frac{ - 3}{1} \longrightarrow - 3 } \\ \displaystyle \large{r = \frac{ 9}{ - 3} \longrightarrow - 3 } \\ \displaystyle \large{r = \frac{ - 27}{9} \longrightarrow - 3 }[/tex]

Therefore, the common ratio or r-value is -3.

To find the 7th term of sequence, you can by using the General Geometric Terms.

General Term of Geometric

[tex] \displaystyle \large{a_n = a_1 {r}^{n - 1} }[/tex]

a1 is defined as the first term of sequence.

r is common ratio.

n is the term.

Since we want to find 7th term:

[tex] \displaystyle \large{a_7 =1{( - 3)}^{7 - 1} } \\ \displaystyle \large{a_7 =1{( - 3)}^{6} } \\ \displaystyle \large{a_7 =729 }[/tex]

Therefore, the 7th term of this sequence is 729.

Let me know if you have any questions!

Answer:

[tex]y=\displaystyle\frac{1}{2}x+1[/tex]

Step-by-step explanation:

Hi there!

Slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept

We're given that the slope is [tex]\displaystyle\frac{1}{2}[/tex]. Plug this into [tex]y=mx+b[/tex]:

[tex]y=\displaystyle\frac{1}{2}x+b[/tex]

Now, to solve for the y-intercept, plug in the point (6,4) and solve for b:

[tex]4=\displaystyle\frac{1}{2}(6)+b\\\\4=3+b\\b=1[/tex]

Therefore, the y-intercept of the line is 1. Plug this back into [tex]y=\displaystyle\frac{1}{2}x+b[/tex]:

[tex]y=\displaystyle\frac{1}{2}x+1[/tex]

Answer:

17 A...... x=56

17 B...... x=4

Step-by-step explanation:

lets start with 124

f-a is 180 degrees

we know 124 so 180-124

56 degrees under the 124

c-e is also 180 degrees

we know 6x

lets say the other degree is y

so 180=6x+y

but the y is inside the triangele, which is what we need

so the angles added up inside the triangle is

56+2x+y=180 degrees because thats what the angle measurements equal for a triangle

so 56+2x+y=180

subtract 56 from both sides

2x+y=124

divide both sides by 2

x+y=62

6x+y=180

x+y=30

124+x=180

x=56

x+y=62

56+y=62

y=6

x(56)+y(6)=62

2. problem

triangle angles must equal 180 degrees

f angle... lets say is y

so

4x+65+y=180

subtract 65 from both sides

4x+y=115

get x by itself

so -y from both sides

Answer:

t = 41.6 (the 6 is repeating)

Step-by-step explanation:

2.5t + 350 = 3t + 225

Subtract 2.5t from both sides to get:

350 = 3t + 225

Now subtract 225 from both sides to get:

125 = 3t

Divide both sides by three.

t = 41.6 (the 6 is repeating)
