3x - y = 12
Answer:
x=5
y=3
Step-by-step explanation:
7x=35
x= 5
3 x 5 - y= 12
15-y = 12
y= 15 - 12

For a science experiment, Mr. Barrows divides 3/4 cup of salt into small jars, each containing 1/10 cup. If he has 1/7 cup of salt left over, how many jars does he fill? Enter an expression you could use to solve the problem.
Answer:
Kindly check explanation
Step-by-step explanation:
Given that :
Initial cup of salt = 3/4 cups ; divided into small jars
Fraction of salt in small jars = 1/10 cup
Fraction left over = 1/7 cup
Number of jars filled?
The fraction divided into the jars :
Initial amount - left over
3/4 - 1/7
(21 - 4) / 28
17 / 28
Fraction of salt per jar = 1/10
Number of jars filled :
Total fraction divided into jars / fraction of salt per jar :
(17 / 28) ÷ (1 /10)
(17 / 28) * (10 / 1)
170 / 28
= 6.0714
= 6 jars

If the terminal side of an angle falls in quadrant IV, then the secant value is?
zero
positive
negative
Answer:
it is positive
Step-by-step explanation:
Secant is just sec which is positive in quadrant 4
If the terminal side of an angle falls in quadrant [tex]IV[/tex], then the secant value is positive .
What is quadrant ?Quadrant is a region defined by the two axes ([tex]x[/tex]-axis and [tex]y[/tex]-axis) of the coordinate system. When the two axes, [tex]x[/tex]-axis and [tex]y[/tex]-axis, intersect each other at [tex]90 ^0[/tex], the four regions so formed are the quadrants. These regions include both positive and negative values of [tex]x[/tex]-axis and [tex]y[/tex]-axis, called coordinates.
We know that,
In trigonometry, trigonometric functions i.e. Sinθ, Cosθ, Tanθ, Cosecθ, Secθ, Cosecθ, the sign of value of all these trigonometric functions varies in every quadrant.
In first quadrant Sinθ, Cosθ, Tanθ, Cosecθ, Secθ, Cotθ are positive.
In second quadrant Sinθ and Cosecθ are positive.
In third quadrant Tanθ and Cotθ are positive.
In fourth quadrant Cosθ and Secθ are positive.
So, from the above statements we can say that the value of secant in quadrant [tex]IV[/tex] is positive .
Hence, we can say that if the terminal side of an angle falls in quadrant [tex]IV[/tex], then the secant value is positive .

WILL GIVE BRAINLIEST ASAP PLZ
Answer:
Therefore the answer is B)
Step-by-step explanation:
so we have to find the inverse function.
g(x) = -1/(x-2) +3
y = -1/(x-2) +3
x = -1/(y-2)+3
x - 3 = -1/(y-2)
(x - 3)^-1 = -(y-2)^-1*-1
1/(x-3) = -y+2
1/(x-3) -2 = -y
-1(-y) = -1[1/(x-3) -2]
y = -1/(x-3) + 2
or y = 1/(-x+3) + 2

Joe is responsible for reserving hotel rooms for a company trip. His company changes plans and increases how many people are going on the trip, so they need at least 50 total rooms. Joe had already reserved and paid for 16 rooms, so he needs to reserve additional rooms. He can only reserve rooms in blocks, and each block contains 8 rooms and costs $900
Answer:
He is going to pay 40*900= $36000 for the reservationStep-by-step explanation:
Step one:
We are told that they need at least 50 total rooms.
Joe has paid for 16 rooms since Joe can only reserve rooms in block, and a block has 8 rooms, then Joe has paid for 2 blocks.
There is a deficit of 50-16= 34rooms
Required
The Number of blocks Joe need to reserve in addition is 34/8
=4.25
The blocks can not be in decimal, so we need to approximate, which is 5 blocks
Therefore Joe is going to reserve 5*8= 40 rooms
He is going to pay 40*900= $36000 for the reservation
Find the Y and X interprets for:
5x-10y= 30
Answer:
x-intercept: 6
y-intercept: -3
Step-by-step explanation:
5x - 10y + 30
Start with: 5x = 30
divide the 5 with 30:
5x = 30
5 5
and 30 divide 5 is 6.
then do: -10y = 30
-10y = 30
-10 -10
30 divide -10 is -3.
