Step-by-step explanation:
Since you can't directly solve for [tex]y[/tex] in this question, we will use substitution to solve for
[tex]{\large{\boxed{\mathbb{QUESTION}}}[/tex]
What would y equal in this equation?
[tex]\begin{bmatrix}3+\frac{4}{1}y=5\\ x+2=0\end{bmatrix}[/tex]
[tex]{\large{\boxed{\mathbb{SOLVE\:FOR\:Y}}}[/tex]
[tex]3+\frac{4}{1}y=5[/tex]
First, we will subtract 3 from both sides of the equation
[tex]\frac{4}{1}y=2[/tex]
Simplify
[tex]{4}y=2[/tex]
Divide both sides by 4
[tex]y=\frac{1}{2}[/tex]
[tex]{\large{\boxed{\mathbb{SOLVE\:FOR\:X}}}[/tex]
[tex]x+2=0[/tex]
subtract 2 to both sides
[tex]x=-2[/tex]
[tex]{\large{\boxed{\mathbb{ANSWER}}[/tex]
[tex]y=\frac{1}{2}[/tex] [tex]x=-2[/tex]_____________________________________
If we didn't use the method with substitution and had our equation being
[tex]3+\frac{4}{1y}=5x+2[/tex]
our answer would've been
[tex]y=\frac{-4}{-5x+1}[/tex], I highly doubt this would be the right answer.

Aiden receives a pay rise of 15%, which increases their pay to $17,250. Calculate his salary before the increase.
Answer:
$15,000
Step-by-step explanation:
Let P represent Aiden's current pay.
If they receive a pay rise of 15%, that means they receive their original pay plus 15% of that original pay.
P + 0.15P = 17250
1.15P = 17250
P = 17250/1.15 = 15000
His salary before the increase was $15,000.
Answer:
$14662.5
Step-by-step explanation:
Aiden receives a pay rise of 15%
increases their pay to $17,250
15% of $17,250 is $2587.5 therefore $17,250 - $2587.5 is his salary before the increase which is 14662.5 so aiden had $14662.5 before his salary increase

2. The electrical resistance R of a wire varies inversely with the square of its diameter d. If a wire with a
diameter of 3 millimeters has a resistance of 0.4 ohm, find the resistance of a wire having the same
length and a diameter of 8 millimeters.
Answer:
[tex]0.225 \Omega =225 m\Omega[/tex]
Step-by-step explanation:
We know (Ohm second law) that [tex]R= \frac{k}{d^2}[/tex] where k inlcudes the rest of the parameters (material, lenght). In our situation we have k= [tex]0.4\cdot9 \Omega mm^2[/tex]. The moment the diameter becomes 8mm R becomes
[tex]R= {{0.4\cdot 9}\over{16}} \Omega = 0.225 \Omega[/tex]

What is the y-intercept?
Answer:
y- intercept = 4
Step-by-step explanation:
The y- intercept is the point on the y- axis where the graph crosses the y- axis
In this case that is the point (0, 4 ) , then
y- intercept = 4

D. –4
Answer:
D. -4
Step-by-step explanation:
the x-intercept of the graph of f(x)=3log(x-5)+2 is:
Answer:
C
Step-by-step explanation:
To find the x- intercept let f(x) = 0 , then
3log(x - 5) + 2 = 0 ( subtract 2 from both sides )
3log(x - 5) = - 2 ( divide both sides by 3 )
log(x - 5) = - [tex]\frac{2}{3}[/tex] , then
x - 5 = [tex]10^{-\frac{2}{3} }[/tex] ( add 5 to both sides )
x = [tex]10^{-\frac{2}{3} }[/tex] + 5 → C

Estimate g(14). (Use the midpoint to get the most precise estimate.)
I know how to apply the midpoint theorem, but I don't know where I should start my intervals.
We have that for the Question "I know how to apply the midpoint theorem, but I don't know where I should start my intervals." it can be said that
Where you start your intervals are at the (x,y) co-ordinate of the Reference points
From the question we are told
I know how to apply the midpoint theorem, but I don't know where I should start my intervals.
Generally the equation for the midpoint is mathematically given as
[tex]m=\frac{x1+x2}{2},\frac{y1+y2}{2}[/tex]
Naturally the midpoint of two point is the point in between the reference points where distances from them are equal
Therefore
Midpoints co-ordinates simply considers the co-ordinate of the two main reference points.(x,y)
Hence
Where you start your intervals are at the (x,y) co-ordinate of the Reference points

To change a fraction to o percentage , multiply by 100% , so
[tex]\frac{16}{128}[/tex] × 100%
= 0.125 × 100%
= 12.5%
Solve the Quadratic equation
8n²-56=48n
Answer:
n = {-1, 7}
Step-by-step explanation:
8n² - 56 = 48n
Subtract 48n from both sides
8n² - 48n - 56 = 0
Divide both sides by 8
n² - 6n - 7 = 0
Factor
alternately use the quadratic equation or complete the square
(n - 7)(n + 1) = 0
n = {-1, 7}

Identify the similar triangles.
ΔHFE=
ΔHFE=
∆HFE is similar to ∆HFG and ∆ HEG (they all are right triangles and have the same, shape.)
The given triangle ΔHFE is similar to triangle GFH and triangle GHE.
What are similar triangles?Similar triangles are two triangles that have the same shape but may differ in size. They have corresponding angles that are congruent and corresponding sides that are proportional.
Here,
Since triangle HFE is similar to triangle GFH,
∠HEF = ∠GHF,
∠FHE = ∠HGF, and ∠HFE = ∠HFG
Similarly
ΔHFE is similar to triangle ΔGHE.
Similar triangles are useful in many areas of mathematics and in the real world, such as in architecture, engineering, and cartography, where they are used to make scale models of buildings and other structures.
Thus, the given triangle ΔHFE is similar to triangle GFH and triangle GHE.

Answer:
174 m^2
Step-by-step explanation:
9 * 5 = 45
9 * 5 = 45
9 * 3 = 27
9 * 3 = 27
5 * 3 = 15
5 * 3 =15
45+45+27+27+15+15 = 174 m^2
Hope this is helpful.
Answer:
174 m²
Step-by-step explanation:
9 * 5 = 45 (that's the bottom and top areas)
9 * 3 = 27 (that's both the bigger sides areas)
5 * 3 = 15 (that's both the smaller sides areas)
Now you have to double:
45 * 2 = 90
27 * 2 = 54
15 * 2 = 30
Now sum:
90 + 30 + 54 = 174

Answer:
1800.
Step-by-step explanation:
If N is the first letter the next 2 letters will be the number of permutations of 2 from 25 = 25!/ (25-2)!
= 600.
If the first number is M or P the number is the same so that makes 1800 possibilities.
