Determine the equation of the line parallel to the line y=34x+2
y=3/4x+2 that passes through the point (4, -3).
Answer:
y = 34x - 139 (y = 34x + 2)
y = [tex]\frac{3}{4}[/tex]x - 6 (y = 3/4x +2)
Step-by-step explanation:
(I'm not sure if the two equations were the same or not, but I provided the answers just in case.) Parallel lines are two lines that have the same plane and slope but never intersect. To find the equation, use the formula y - [tex]y_{1}[/tex] = m (x - [tex]x_{1}[/tex])

find the measure of the arc or angle indicated. assume that lines which appear tangent are tangent. just enter the number.
Answer:
C. 60°
Step-by-step explanation:
The vertical angle formed inside a circle when two chords intersect each other is equal to half the sum of the measures of the intercepted arcs, based on the intersecting chords angle measure theorem.
Thus:
90° = ½(120° + arc TA)
Multiply both sides by 2
2*90 = 120 + arc TA
180 = 120 + arc TA
Subtract 120 from each side
180 - 120 = arc TA
60° = arc TA
Arc TA = 60°

Given the equation: I + I → I2 + 35 kcal This equation shows that the formation of an iodine molecule is an A) endothermic process in which energy is absorbed B) exothermic process in which energy is released C) exothermic process in which energy is absorbed D) endothermic process in which energy is released
Answer:
A) endothermic process in which energy is absorbed
Step-by-step explanation:
A thermochemical reaction equation is a chemical reaction equation in which the enthalpy of reaction is written after the symbols of reactants and products.
The importance of thermochemical reaction equations is that they show us whether energy was absorbed or evolved in a reaction as well as the magnitude of energy absorbed or evolved.
When the enthalpy of reaction is positive, the reaction is endothermic and energy is absorbed. When the enthalpy of reaction is negative, the reaction is exothermic and energy is evolved or released.
The enthalpy of the reaction I + I → I2 + 35 kcal is positive hence the reaction is an endothermic process in which energy is absorbed.
The equation shows that the formation of an iodine molecule is an A. endothermic process in which energy is absorbed.
What is an endothermic process?It should be noted that an endothermic process is where heat is transferred from the surroundings to the systems. In this case, the system has gained heat from the surroundings.
The change in enthalpy, delta H is positive for an endothermic process. When the enthalpy of reaction is positive, the reaction is endothermic and energy is absorbed. The enthalpy of the reaction is positive as illustrated in this case.

Windows on the International Space Station are shown below. Suppose the long base of the window is 15.2 feet and the short base is 11.2 feet. The perpendicular height from one base to the other base is 8.4 feet. Draw one of the trapezoid-shaped windows on grid paper and label its dimensions. Describe the process you would use to find the area of one trapezoid-shaped window. (2 points)
Calculate the area of the window using the dimensions given in Part A. Show your work and explain your reasoning. (4 points)
Answer:
The formula is Area = base+base/2 x height.
Step-by-step explanation:
This means that we need to add both bases, then divide that by 2. The quotient of that gets multiplied by the height, and you have your answer.

The varsity soccer team has 20 players. Three of the players are trained to be goalies while the remaining 17 can play any position. Only 11 of the players can be on the field at once.
(a) We want to find the number of possible groups of 11 players the coach can choose. Is this a
permutation or a combination?
(b) If the coach wanted to choose her 11 starters at random by drawing names from a hat, how many possible groups of 11 starters could she choose?
(c) The coach wants to make sure there is exactly one goalie on the field. How many ways can the
coach choose a lineup of 11 players if exactly 1 player must be a goalie?
Answer:
Combination.
167960
58344
Step-by-step explanation:
A.)
Choosing 11 players from 20 ; here the order in which the players are chosen does not matter, hence it is a combination problem.
2.)
Using nCr
n = 20 ; selection, r = 11
nCr = n! / (n-r)!r!
20C11 = 20! / 9!11!
20C11 = 167960
3.)
1 goalie 10 players

matthew lives 6 miles east of the school drew lives 8 miles north of the school. what is the shortest distance between the two houses? A. Two miles b. 10 miles c. 100 miles d. 4 miles
Answer:
Step-by-step explanation:
2miles
The required shortest between the two houses is given as 10 miles. Option B is correct.
What are Pythagorean triplets?In a right-angled triangle, its side, such as the hypotenuse, is perpendicular, and the base is Pythagorean triplets.
Here,
Matthew lives 6 miles east of the school drew lives 8 miles north of the school.
Let's assume, the position of Mathew and drew house create the right angle with the school,
hypotenuse distance between Mather and Drew's house be x,
Applying the Pythagoras theorem,
x = √[8² + 6²]
x = √[100]
x = 10 miles
Thus, the required shortest between the two houses is given as 10 miles. Option B is correct.

The measure of ∠BCF is 60°, and the measure of ∠FCG is 35°. Which equation can you use to find the measure of ∠BCG?
Answer:
x = ∠BCF+ ∠FCG
Step-by-step explanation:
According to the given measure, we can say that, line Fc bisects ∠BCF and ∠FCG and the sum of ∠BCF and ∠FCG is ∠BCG. Mathematically;
∠BCF+ ∠FCG = ∠BCG
Given
∠BCG = 60degrees
∠FCG = 35degrees
Let x be equal to ∠BCG
Hence the required equation will be;
∠BCF+ ∠FCG =x
Swap sides
x = ∠BCF+ ∠FCG

sooo who wants brainlest ??
Answer: 60%
If I’m understanding this problem correctly (I believe it wants me to isolate the group), we’re taking 27% (0.27) of the total men who answered the survey which equated to 45% (0.45)
First we’ll change 0.27 and 0.45 to 27 and 45. So, if 45 is our maximum, then if we divide 27 by 45, we’ll get the value 0.6–> if we multiply that by 100, we’ll get 60%.
Thus, 60% of men within that gender group preferred suspense movies.

Janine has 48 hockey cards in one book and 105 hockey cards in another book. The hockey cards come in packages of 5 cards. If Janine bought all of her hockey cards in packages, how many packages did she buy?
Answer: 31
Step-by-step explanation:
Janine has 48 hockey cards in one book and 105 hockey cards in another book. Therefore, the total hockey cards will be:
= 48 + 105
= 153 hockey cards
Since the hockey cards come in packages of 5 cards, the number of packages that she will buy will be:
= 153/5
= 30 3/5
= 31
Therefore, she'll buy 31 packages

A baker can decorate one cake in
hour.
What is the total number of hours the baker needs to decorate 4 cakes?
Answer:
4 hours
Step-by-step explanation:
It takes one hour to make one cake, so we can put that as a ratio of 1:1.
4 cakes means you multiplied one side by 4, as it is 4 cakes and not one, so you multiply the time by 4 too.
4 hours
Answer:
4 hours is needed for the baker to decorate 4 cakes.
