Solve the inequality.
−3y < −14
Answer:
y<14/3
Step-by-step explanation:
−3y < −14
dividing both side by -3
-3y/-3 <-14/-3
y<14/3
The solution of the inequality will be equal to y<14/3.
What is inequality?When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than relationship between variables and the numbers.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
The given inequality will be solved as,
−3y < −14
Dividing both sides by -3 and solving further.
-3y/-3 <-14/-3
y < 14

Which of these equations has no solution? OA) m = 0 OB) m = m = O c) 2m + 1 = m - 2 od m + 4 = m-4
Answer:
OD is the correct answer
Answer:
OD ) m + 4 = m - 4
Step-by-step explanation:
m + 4 = m - 4
m = m - 4 - 4
m = m -8
m -m = - 8
0 ≠ 8
So, this has no solution
help me find the rate of change
Answer:
3
Step-by-step explanation:
To find the rate of change, we want to use the slope formula: (y₂ - y₁) / (x₂ - x₁)
Plug in these values using two given points. I will use the first and last points.
(1, -2) & (13, 34)
(34 - (-2)) / (13 - 1)
Simplify the parentheses.
= (34 + 2) / (12)
= 36/12
Simplify the fraction.
36/12
= 3
This is your slope.

1. x^2 + 3x - 4 = 0
2. 2x^2 - 4x - 3 = 0
3. x(x - 2) = 4
4. 9x^2 + 12x + 4 = 0
5. x^2 + 2x = 1
Answer:
1. x^2 + 3x - 4 =0
x^2 + 3x = 4
x + 3x = √4
4x = 2
x =2/4
x = 1/4
2. 2x^2 - 4x - 3 = 0
2x^2 - 4x = 3
2x^2 - x = 3/4
2x - x = √3/4
x = √3/4
3.x(x-2) = 4
x^2 - 2x = 4
x - 2x = √4
- x = 2
x = -2

The time the bus should arrive at School Road from Hope Street is 08 : 04.
The time of the latest bus that Jo can catch from the Bus Station is 07 00.
The time the bus takes to travel from the bus station to School Road is 14 minutes.
How to find the time ?The table shows that when a bus leaves for School Road from Hope Street, at 07 54, it will arrive on School Road at 08 04.
The time it takes from the bus station to School road is:
= Arrival time at school road - Departure time from Bus station
= 08 04 - 07 50
= 14 minutes
If Jo wants to be in school road at 8 am by the latest, she needs to leave before :
= 8 am - 14 minutes
= 07 46
The only bus leaving before this time is the 0700 bus from the Bus Station.

Can the measurement from △DEF be determined using only the Law of Cosines? State whether each measurement can be determined using only the Law of Cosines by answering “yes” or “no”.
m∠D =
m∠E =
DE =
9514 1404 393
Answer:
∠D - no∠E - noDE - yesStep-by-step explanation:
With a single application of the Law of Cosines, you can only find one of an unknown side or an unknown angle. The other three elements in the 4-variable equation must be specified.
However, a single application of the LoC can be used to find DE. Then, knowing the three sides, either of the unknown angles can be found from an additional application of the LoC.
So, the answer is "it depends." It is yes to all if finding DE first is allowed. It is "no" to the angles if they must be found without finding DE first.

What is an equation of the line that passes through the point (2, 2) and is parallel to
the line x -
2y = 4?
Answer:
you wold have to graph it just put it in the caculater like that
Step-by-step explanation:
Answer: y- 2 = -1/2(x - 2)
Step-by-step explanation:
We need to rewrite it as y=mx+b.
x - 2y = 4
2y = - x + 4
y = -1/2x + 4/2
y = -1/2x + 2
The slope for x - 2y = 4 is -1/2.
In addition, the slope of two parallel line would be the same, the slope of the line that pass through the point (2,2) would be -1/2.
y- y1 = m(x- x1)
y- 2 = -1/2(x - 2)

How would you do this maths question?
Answer:
Step-by-step explanation:
First you take the 142+B=180
because those 2 are supplementary
B=38
and you see the 2 lines on the 2 sides that means those two sides are equal to each other and the angles corresponding with them are also equal to each other.
and a triangle= 180 degrees
A and E are the same so A=E
180-B(38)= 142
and because A=E you do 142/2= 71
and now that you have A and E you don't need A or B for the last part so
E+(x)=180 because those two angles are supplementary.
and E is 71 so...
71+(x)=180 ---------180-71=x
X=109
