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
Challenge Andy and Emily each go to a hardware store to buy wire. The
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
12*23=276
Will by 276 inches or 276x
Emily
15yards needed
15*3*12=540
Will by 540 inches or 276x
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.

A deck of Uno cards has 4 colors (suits): Red, Yellow, Green, Blue
Each color has cards numbered 1 to 9,
so the total number of these cards = 49 = 36
(An Uno deck also has other, special cards, but for this question, those special cards are removed for the
deck. Only the numbered cards are used.)
a) Event E = Randomly selecting an UNO card that is Red.
What is the probability of event E?
(Enter a fraction; it does not have to be reduced.)
b) Event F = Randomly selecting an Uno card that is some number from 1 to 6 of any of the 4 colors.
What is the probability of event F?
(Enter a fraction; it does not have to be reduced.)
c) How many cards are in the intersection of events E and F?
d) P(E and F) = the probability of choosing a card in the intersection of events E and F: P(E and F) = ?
e) Let event G = E or F.Use the General Addition Rule to compute P(G): P(G) = P(E) + P(F) - P(E and F)
f) How many cards are in event G?
Question Help: D Video 1 Video 2 Message instructor
Answer:
A) 1/9
B) 2/3
C) 6 (I think)
D) 6 (isn't it the same as question C?)
Step-by-step explanation:
Remember this formula:
Probability = number of favorable outcomes divided by the number of possible outcomes
a) 4 / 36 = 1/9
b) 6 * 4 = 24 / 36 = 2/3
c) 24 - 18 = 6
d) 6

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]
Nathaniel is deciding between two parking garages. Garage A charges an initial fee of $8 to park plus $6 per hour. Garage B charges an initial fee of $11 to park plus $5 per hour. Let AA represent the amount Garage A would charge if Nathaniel parks for tt hours, and let BB represent the amount Garage B would charge if Nathaniel parks for tt hours. Write an equation for each situation, in terms of t,t, and determine the hours parked, t,t, that would make the cost of each garage the same.
Answer:
tt = 3 would make the cost of each garage the same.
Step-by-step explanation:
Garage A: $8 + $6(h)
AA = $8 + $6(tt)
Garage B: $11 + $5(h)
BB = $11 + $5(tt)
If AA = BB
then,
$8 + $6(tt) = $11 + $5(tt)
($6-$5)(tt) = $11 - $8
$1(tt) = $3
tt = 3

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 = 5.5Which ordered pair is a solution to the linear inequality below? y>-2x+7

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
