y=6
Step-by-step explanation:
[tex]75 - 3.5y - 4y = 4y + 6[/tex]
Collect like terms and simplify
[tex] - 3.5y + 4y - 4y = 6 - 75 \\ - 11.5y = - 69[/tex]
Divide both sides of the equation by-3.5
[tex] \frac{ - 11.5y}{ -11.5} = \frac{ - 69}{ - 11.5} [/tex]
Simplify
[tex]y = 6[/tex]
The value of the y in the given equation is 6.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
For example, 3x – 5 = 16 is an equation.
Given that, an equation, 75 - 3.5y - 4y = 4y + 6, we need to find the value of y,
75 - 3.5y - 4y = 4y + 6
Combining the like terms,
75 - 6 = 4y + 4y + 3.5y
69 = 11.5y
y = 6
Hence, the value of the y in the given equation is 6.

What is 2M?
M=[3 5]
[-4 0]
Answer:
2M will be:
[tex]2\begin{pmatrix}3&5\\ -4&0\end{pmatrix}=\begin{pmatrix}6&10\\ -8&0\end{pmatrix}[/tex]
Therefore, the 2nd option is true.
Step-by-step explanation:
Given the matrix
[tex]M=\begin{pmatrix}3&5\\ -4&0\end{pmatrix}[/tex]
Multiplying by 2 will basically be a scalar multiplication.
Therefore, multiply each of the matrix elements by a scalar.
[tex]2M=2\begin{pmatrix}3&5\\ \:-4&0\end{pmatrix}[/tex]
[tex]=\begin{pmatrix}2\cdot \:3&2\cdot \:5\\ 2\left(-4\right)&2\cdot \:0\end{pmatrix}[/tex]
[tex]=\begin{pmatrix}6&10\\ -8&0\end{pmatrix}[/tex]
Hence, 2M will be:
[tex]2\begin{pmatrix}3&5\\ -4&0\end{pmatrix}=\begin{pmatrix}6&10\\ -8&0\end{pmatrix}[/tex]
Therefore, the 2nd option is true.
Line m contains the points (−3, 2) and (5 , 1). Line n contains the points (2 , 7) and (1, −1) . Which statement is TRUE about lines m and n?
A. The lines are parallel.
B. The lines are coincident.
C. Both lines intersect but are neither parallel nor perpendicular.
D. The lines are perpendicular.
9514 1404 393
Answer:
D. The lines are perpendicular
Step-by-step explanation:
The first line has a rise of (1-2) = -1 for a run of (5-(-3)) = 8.
The second line has a rise of (-1-7) = -8 for a run of (1-2) = -1.
Then the slopes are -1/8 and -8/-1 = 8, which are negative reciprocals of each other. Lines with slopes having that relationship are perpendicular.

a science teacher has 12 g of marble chips. Each lab station needs 0.5 g of marbles chips. How many lab station can she supply?
Answer:
24
Step-by-step explanation:
Since each lab station needs 0.5 grams of chips, we have to divide 0.5 from 12.
12/0.5 = 24
f(x) = 3x + 5
g(x) = 4x^2 – 2
h(x) = x^2 – 3x + 1
Find f(x) – g(x) – h(x).
Answer:
f(x) – g(x) – h(x) = -5x^2 + 6x + 6
Step-by-step explanation:
Copy f(x) as is: f(x) = 3x + 5
Negate g(x): -g(x) = -4x^2 + 2
Negate h(x): -h(x) = -x^2 + 3x - 1
Now combine like terms:
f(x) – g(x) – h(x) = -5x^2 + 6x + 6

Explain how solving -7y > 161 is different from solving 7y > -161.
Answer:
Sample response: Both inequalities use the division property to isolate the variable, y. When you divide by a negative number, like –7, you must reverse the direction of the inequality sign. When you divide by a positive number, like 7, the inequality sign stays the same. The solution to the first inequality is y > -23, and the solution to the second inequality is y <>

15. The diameter of a circle is given as 10 cm, correct to the nearest cm. Calculate:
a) the maximum possible circumference
b) the minimum possible area of the circle consistent with this data
Answer:
10cm correct to nearest cm" means the diameter could be arbitrarily close to (but less than) 10.5 cm. So the maximum possible circumference is 10.5π cm.
"10cm correct to nearest cm" also means that the diameter could be arbitrarily close to (but greater than) 9.5 cm. So the minimum possible area is π(9.5)²/4 cm²

Part A: what is the measure of QRS?
Part B; what is the measure of Q?
Answer:
QRS = 66° and Q = 95°
Step-by-step explanation:
Required Answer
[tex]\huge {\boxed{\sf{∠QSR=66⁰}}}[/tex]
[tex]\huge {\boxed{\sf{∠Q=95}}}[/tex]
Correct Question:
To find of :
∠QSR∠QExplanation:
∠QSR+∠QRT=180⁰
Reason:
linear pair
.°. ∠QSR+114⁰=180⁰
∠QSR=180⁰-114⁰
∠QSR=66⁰
Can also be done as follows:
To find value of ∠QSR first we have to find y
y⁰+(5y)⁰=114
Reason:
exterior opposite angle is equal to sum of interior angles
6y=114
y=114/6
y=19
y⁰+(5y)⁰+∠QSR=180⁰
Reason:
sum of angles of triangle =180⁰
6y+∠QSR=180⁰
6×19+∠QSR=180⁰
114+∠QSR=180⁰
∠QSR=180⁰-114⁰
∠QSR=66⁰
From second part we get the value of y
.°.∠Q=5×19
∠Q=95
Give the domain and range of the relation.
Answer:
The domain is the set of all first elements of ordered pairs (x-coordinates). The range is the set of all second elements of ordered pairs (y-coordinates). Only the elements "used" by the relation or function constitute the range. Domain: all x-values that are to be used (independent values).

The volume of the large cube is 125 cubic inches. The volume of the small cube is 27 inches. What is the difference between the length of one side of the large cube and the length of one side of the small cube?
Answer:
2cmStep-by-step explanation:
Step one:
given data
for the large cube
the volume= 125cm^3
we know that volume = l*l*l
volume=l^3
we want to find l, so we have to cube both sides
125=l^3
l=∛125
l=5cm
Step two:
given data
for the large cube
the volume= 27cm^3
we know that volume = l*l*l
volume=l^3
we want to find l, so we have to cube both sides
27=l^3
l=∛27
l=3cm
The difference between the length of one side of the large cube and the length of one side of the small cube=5-3= 2cmHURRY PLEASE!! I’ll mark you as brainliest!! im being timed
