Answer:

x = 12

Step-by-step explanation:

(8x - 1) + (3x + 4) + (3x + 9) = 180 degrees

14x + 12

180 - 12 = 168

14x = 168

/14 | /14

x = 12

Top left angle: (8x - 1)

8*12 - 1

96 - 1

= 95

Sorry! gtg I hope this helps!

Misha Larkins [42]

Answer:

The percentage of college seniors with "Other" majors is 32%.

Step-by-step explanation:

The total number of college seniors surveyed is, N = 400.

The number of college seniors with "Other" majors is, n = 128.

The percentage of a value of x from N total is given as follows:

$\text{Percentage of}\ x=\frac{x}{N}\times 100\%$

Compute the percentage of college seniors with "Other" majors as follows:

$\text{Others}\%=\frac{n}{N}\times 100\%$

$=\frac{128}{400}\times 100\%\\\\=32\%$

Thus, the percentage of college seniors with "Other" majors is 32%.

write an equation in slope intercept form of a line that passes through the point (14, 8) and is (a) parallel (v) perpendicular

svet-max [94.6K]

Answer:

$y-8=-\frac{7}{3} (x-14)$

Step-by-step explanation:

We can write the equation of a line in 3 different forms including slope intercept, point-slope, and standard depending on the information we have. We have a point and a slope from the equation. We will chose point-slope since we have a point and can find the slope.

Point slope: $y-y_1=m(x-x_1)$

We must find the slope using the slope formula.

Slope: $m=\frac{y_2-y_1}{x_2-x_1}$

We substitute $x_1=4\\y_1=9$ and $x_2=-3\\y_2=6$

$m=\frac{6-9}{-3-4}$

$m=\frac{6-9}{-3-4}=\frac{-3}{-7} =\frac{3}{7}$

$m\neq \frac{3}{7}$ in our new equation because it is perpendicular to it. This means we will need to change it into its negative reciprocal which is $m=-\frac{7}{3}$ .
