Let me know if you need explanation.
Answer:
y = 4/3x+4
Step-by-step explanation:
First, we must find the slope. (m=y2-y1/x2-x1)
Once you subsitute the numbers, you'll get 12/9. Reduce that to 4/3
After that, replace y = mx +b with the any of the ordered pairs. I chose 3 and 8.
So. 8=4/3(3)+b (b is the y intercept) 3/4 is our slope, 8 is the y, and 3 is the x.
So, multiply 3/4 by 3. You'll get 4.
Then, subtract 4 on both sides (8-4) which gets you 4.
Therefore, b (y intercept) = 4.
y = mx+b
y=4/3x+4.
A retailer was given a trade discount are 15% and cash discount of 6% by the wholesaler. How much did the retailer pay for a good marked price for $3745
Answers
===================================================
Explanation:
If you're given a 15% discount, then you still have to pay the remaining 85% (because 100% - 15% = 85%)
Rewrite 85% into 0.85
The multiplier for "15% discount" is 0.85
Similarly, the multiplier for a 6% discount is 0.94; note how 100% - 6% = 94% = 0.94
When we have multiple discounts chained together like this we find the product of the multipliers. So we multiply the 0.85 and 0.94 to get
0.85*0.94 = 0.799
After chaining together the two discounts, you will have to pay 79.9% of the original value. This means the overall discount is 20.1%
Take the result of 0.799 and multiply that with the marketed price of $3745 to get the final answer
0.799*3745 = 2,992.255 which rounds to 2,992.26

In triangle XYZ, m∠Z > m∠X + m∠Y. Which must be true about △XYZ?
m∠X + m∠Z 90°
∠X and∠Y are complementary
m∠X + m∠Y < 90°
Answers
Answer:
m < X + m < Y < 90
Step-by-step explanation:
For the triangle XYZ, m∠Z > m∠X + m∠Y we see that because the total internal angles of a triangle is 180,m∠X + m∠Y < 90° is a true assertion
Option C is correct
What must be true about triangle XYZ?Generally, A triangle's major feature is its total internal angles as 180
Therefore
if m∠Z > m∠X + m∠Y this means that m<z must be greater than 90 degrees
This goes to show us that
m<X + m<Y < 90 because as we earlier mentioned the total internal angles of a triangle is 180 .
In conclusion, For the triangle XYZ
m∠X + m∠Y < 90° is a true assertion

Write an equation passing through the point and parallel to the given line
(4,7); y = 3x + 6
Thank you!
Answers
Answer:
Step-by-step explanation:
y=3x+6
slope is 3, so y=3x+[unknown].
We insert the point (4,7) into the equation.
7=3*4+[unknown]
7=12+[-5]
so the answer is
y=3x-5
Answer:
y = 3x - 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 3x + 6 ← is in slope- intercept form
with slope m = 3
Parallel lines have equal slopes, thus
y = 3x + c ← is the partial equation
To find c substitute (4, 7) into the partial equation
7 = 12 + c ⇒ c = 7 - 12 = - 5
y = 3x - 5 ← equation of parallel line
you need to write equally fraction but the catch is the denominators have to be the same for 1/4

[tex] \dfrac{a}{b+1} - \dfrac{a}{(b+1)^2} = [/tex]
[tex] = \dfrac{b + 1}{b + 1} \times \dfrac{a}{b+1} - \dfrac{a}{(b+1)^2} [/tex]
[tex] = \dfrac{a(b + 1)}{(b+1)^2} - \dfrac{a}{(b+1)^2} [/tex]
[tex] = \dfrac{ab + a}{(b+1)^2} - \dfrac{a}{(b+1)^2} [/tex]

Answer:
Proof
Step-by-step explanation:
[tex] \frac{a}{(b + 1)} - \frac{a}{ {(b + 1)}^{2} } [/tex]
Multiply the first fraction (the numerator and the denominator) by
[tex](b + 1) \\[/tex]
In order to get common denominators for both fractions
[tex] \frac{a(b + 1)}{ {(b + 1)}^{2} } - \frac{a}{ {(b + 1)}^{2} } [/tex]
Then expand the first fraction's numerator and subtract fractions to get your answer
