Answer:
y-y1 = m(x-x1)
y - 2 = 3(x-1)
y=3x-3+2
y=3x-1
Step-by-step explanation:
first you type down point slope formula
then you plug in the information you have point (1,2) 1 is x1 and 2 is y1 m is 3 because m = slope
then you have to distribute the 3 to the x and the -1 and then isolate y
(how to isolate the y) you must do the opposite of -2 which is +2 whatever you do on one side you have to do to the other
then you combine like terms 3x is alone and -3 +2 equals -1

True or False: sec-10.5 is undefined. Explain your answer.
Since no angle has a cosine of 2, the arcsecant of 0.5 is undefined, and the statement that [tex]\sec^{-1}{0.5}[/tex] is undefined is True.
What is the secant of an angle?The secant of angle is given by one divided by the cosine of the angle, that is:
[tex]\sec{\theta} = \frac{1}{\cos{\theta}}[/tex]
The cosine of an angle has values ranging between -1 and 1, hence the values of the seccant are in the following interval:
[tex][1, \infty)[/tex]
The concept of the arcseccant, [tex]arcsec{x} = \theta[/tex] means that angle [tex]\theta[/tex] has a secant value of x.
In this problem, the expression is given by:
[tex]\sec^{-1}{0.5}[/tex]
No angle has a secant of 0.5, as 0.5 is not on the interval [tex][1, \infty)[/tex], hence the statement that [tex]\sec^{-1}{0.5}[/tex] is undefined is True.

At an electronics store, a smart phone is on sale for 35% off the original price of $679. If you use the store credit card, you can receive an additional 15% off the sale price. What is the final price of the smart phone if you use the store credit card? Round to the nearest cent.
If all the relevant discounts are used including the store credit card, the final price of the phone would be $375.15.
The sale price of the phone has been discounted by 35% which makes it:
= Price of phone x (1 - discount)
= 679 x ( 1 - 35%)
= $441.35
Then using the store credit card would reduce this by a further 15%:
= 441.35 x (1 -15%)
= $375.1475
= $375.15
In conclusion, the final price of the phone is $375.15.

What is the degree-measure of an angle travelled by the minute hand from 3:05pm to 3:50pm?
Answer:
270°
Step-by-step explanation:
We know that a full circle is 360°, the shape of a clock, and that the clock is divided into 12 different sections.
Our equation would be: 360 ÷ 12 = 30
3:05 is at the 1 hand and 3:50 is at the 10 hand. Subtract 1 from 10 and you get 9.
9 · 30 = 270, so our angle is 270°

What is the solution to the linear equation?
2 + p = 7/3 + 30
O p= 1
Op=2
O p = 8
O p = 10
The equation 2 + p = 7/3 + 30 is a linear equation, the solution to the linear equation is p = 91/3
How to determine the solution to the equation?The equation is given as:
2 + p = 7/3 + 30
Subtract 2 from both sides
p = 7/3 + 30 - 2
Evaluate the difference
p = 7/3 + 28
Evaluate the sum
[tex]p = \frac{7 + 28 * 3}3[/tex]
Evaluate the sum
p = 91/3
Hence, the solution to the linear equation is p = 91/3

Which is an equation of the line parallel to 4y - 7x = 8 and passes through (-4, 0)?
A. y = 7/4x + 7
B. y = - 7x - 28
C. y = - 7/4x - 7
D. y = 7x + 28
Answer:
A. y = 7/4x + 7
Step-by-step explanation:
y = mx +c
4y -7x = 8
(make y the subject of formulae)
4y = 8 + 7x
divide through by the coefficient of y (4)
y = 2 + 7/4x
7/4 = m1
since the line is parallel m1 = m2
let see : {y -y¹}÷ {x-x1} = 7/4
x¹= -4 , y¹ = 0
{y - 0} ÷ {x- (-4) } = 7/4
cross multiply
4(y - 0) = 7(x+4)
4y - 0 = 7x + 28
4y = 7x +28 +0
4y = 7x + 28
(divide both sides by the coefficient of y)
y = 7/4x +28/4
y = 7/4x + 7

Jimmy and Lauren are
organizing transportation for
a field trip from ACIT. Jimmy
found out that his group has
841 students, and he needs 9
vans and 16 buses to
accommodate. While Lauren’s
group has 351 students, and
she needs 8 vans and 5 buses
for them. How many students
fit in a van and a bus for this
field trip? (please include steps)
Step-by-step explanation:
Jimmy's group : has 841 students
Lauren's group: has 351 students
9 vans 16 buses
8 vans 5 buses
Vans: V
Buses: B
9v + 16b = 841
9v + 16b = 841
-16b -16b
9v/ 9 = 841 /9 - 16b/9
8( 841/9 - 16b/9) +5b = 351
v - (841/ 9 - 16b / 9 )
8 (841 / 9 - 16b/9) +5b = 351
6728/9 - 128b / 9 +5b = 351
-128b/9 + 45b/9 = -83/9b
6728/9 -83/9
- 6728/9 +83/9 = 3159/9 - 6728/9
(9)83b / 9 = -3569 (9)/9
-83b = -3564
-83 -83
B = 43 students
8v + 5b = 351
8v + 5 (43) = 351
8v + 215 = 315
-215 -215
8v = 136
8 8
V = 17 students
43 students can fit on a bus and 17 students can fit in a van.
