Are the students correct? Explain. Trish is the only student who is correct; the slope should be –1, and the line passes through (4, 2). Demetri is the only student who is correct; the slope should be –1, and the y-intercept is 6. Both students are correct; the slope should be –1, passing through (4, 2) with a y-intercept of 6. Neither student is correct; the slope of the parallel line should be 1.

Answer:
D(5, 4), E(14, 7), M(9.5, 5.5)Step-by-step explanation:
As AD = 1/4AB and DE ║ AC, the ratio CE/CB = 1/4, or CE = 1/4CB
Find the coordinates of D:
x = 1 + 1/4(17 - 1) = 1 + 4 = 5y = 5 + 1/4(1 - 5) = 5 - 1 = 4Find the coordinates of E:
x = 13 + 1/4(17 - 13) = 13 + 1 = 14y = 9 + 1/4(1 - 9) = 9 - 2 = 7Find the coordinates of the midpoint M of DE:
x = (5 + 14)/2 = 19/2 = 9.5y = (4 + 7)/2 = 11/2 = 5.5how can I Simplify (5²)⁴

Answer:
[tex]x(3 + y)[/tex]
Step-by-step explanation:
Hi there!
[tex]3x + xy[/tex]
The two terms in this expression are 3x and xy. In both these terms, x is present. Therefore, we can factor x out:
[tex]x(3 + y)[/tex]
We cannot factor this further.
I hope this helps!
Answer:
x(3+y)
Step-by-step explanation:
Hope this helps you
Erica solved the equation −5x − 25 = 78; her work is shown below. Identify the error and where it was made.
−5x − 25 = 78
Step 1: −5x − 25 − 25 = 78 − 25
Step 2: −5x = 53
Step 3: negative five times x over negative five = fifty-three over negative five
Step 4: x = negative fifty-three over five
Step 1: She should have added 25 to each side.
Step 1: She should have divided both sides by −5.
Step 3: She should have divided both sides by −5.
Step 3: She should have multiplied both sides by −5.
Answer:
step 1 was wrong she should have added 25 to both sides
Step-by-step explanation:
step 3 was correct she divided both sides by -5

If K is the ratio of the roots of the polynomial x²+px-q, the value of k/1+k² is:
[tex]\large\underline{\sf{Solution-}}[/tex]
Given Polynomial:
[tex] \rm \longmapsto f(x) = {x}^{2} + px - q[/tex]
Let α and β be the zeros of f(x)
Then:
[tex] \rm \longmapsto \alpha + \beta = - p[/tex]
[tex] \rm \longmapsto \alpha \beta = - q[/tex]
Now, it's given that:
[tex] \rm \longmapsto k = \dfrac{ \alpha }{ \beta } [/tex]
Consider the expression given:
[tex] \rm = \dfrac{k}{1 + {k}^{2} } [/tex]
[tex] \rm = \dfrac{ \dfrac{ \alpha }{ \beta } }{1 + { \dfrac{ \alpha {}^{2} }{ \beta {}^{2} } }} [/tex]
[tex] \rm = \dfrac{ \dfrac{ \alpha }{ \beta } }{ { \dfrac{ \alpha {}^{2} + { \beta }^{2} }{ \beta {}^{2} } }} [/tex]
[tex] \rm = \dfrac{ \alpha }{ { \dfrac{ \alpha {}^{2} + { \beta }^{2} }{ \beta } }} [/tex]
[tex] \rm = \dfrac{ \alpha \beta }{\alpha {}^{2} + { \beta }^{2} } [/tex]
[tex] \rm = \dfrac{ \alpha \beta }{ {( \alpha + \beta )}^{2} - 2 \alpha \beta } [/tex]
[tex] \rm = \dfrac{ - q }{ {p}^{2} + 2q} [/tex]
The cube root of 175616 is:
Answer:
56
Step-by-step explanation:
We can represent 175616 as the product of primes as below:
175616=2×2×2×2×2×2×2×2×2×7×7×7
Grouping the factors to form the triplet, we have:
175616=2×2×2 ×2×2×2 ×2×2×2 ×7×7×7
Taking the cube root, we have:
[tex]\sqrt[3]{175616} = 2*2*2*7[/tex]
Simplifying, we have:
[tex]\sqrt[3]{175616} = 56[/tex]
Hence, the cube root of 175616 is 56

table shows the cost y in dollars for x inches of the wire they need. Andy
needs 23 feet of the wire. Emily needs 15 yards of the wire. How much will
each of them spend for wire?
Answer:
Andy will spend 276y
Emily will spend 540y
Step-by-step explanation:
So for all intents and purposes, x=y
12 inches per 1 foot
3 feet per one yard
Andy:
23ft. needed
