Answer:
{1, -2/5}
Step-by-step explanation:
5x^2 - 3x -2 = 0
x^2 - (3/5)x - 2/5 = 0
( x - (3/10) )^2 - (3/10)^2 - 2/5 = 0
( x - (3/10) )^2 = 2/5+9/100
( x - (3/10) )^2 = (7/10)^2
Take square roots on both sides
x - 3/10 = +/- 7/10
x = 3/10 +/- 7/10
= { 1, -2/5 }

Three rays have a common vertex on a line. Write and solve equations to find the measures of m and n
Answer:
n = 90 - 62
n = 28º
m = 180 - (62 + n + 27)
m = 180 - (62 + 28 + 27)
m = 180 - 117
m = 63º
in the function f(x) = (x+2)2 -3 the minimum value occurs when x is
Answer:
x=2
Step-by-step explanation:
the minimum value of y is when x = 2.
Answer:
The minimum is at x = -2
Step-by-step explanation:
f(x) = (x+2)^2 -3
This is in vertex form
f(x) = ( x-h)^2 +k where (h,k) is the vertex
Since this is an upwards opening parabola the vertex is the minimum
f(x) = (x- -2)^2 -3
The vertex is (-2,-3)
The minimum is at x = -2
Which is the best explanation for why − √ 10 is irrational?
Step-by-step explanation:
- square root of 10 is irrational because it is less than zero. - square root of 10 is irrational because it is not a whole number.
Upon prime factorizing 10 i.e. 21 × 51, 2 is in odd power. Therefore, the square root of 10 is irrational.

At Walmart, a $525 bicycle is marked, "Get a 30% discount." What is the sale
price of the bicycle?
Answer:
367.50
Step-by-step explanation:
First find the discount
525 * 30%
525 * .30
157.50
Subtract this from the price
525-175.50
367.50
This is the new price
Answer:
367.5
Step-by-step explanation:
30% means 0.30
1 - 0.30 = 0.70
525 x 0.70 = 367.5

Carly takes a taxi from her house to her friends. Their houses are 6km apart. The taxi driver charges a flat fee of $10 plus $0.25/km. This can be modeled using the equation: C=0.25+10, where X represents the distance travelled in km and C represents the cost in dollars. How much will the taxi ride cost?
Answer:
$11.50
Step-by-step explanation:
0.25 times 6= 1.5, plus 10= 11.50

At the moment a certain medicine is injected, its concentration in the bloodstream is 120 milligrams per liter. From that moment forward, the medicine's concentration drops by 30% percent each hour. Write a function that gives the medicine's concentration in milligrams per liter, C(t), t hours after the medicine was injected. If anyone responds, thank you <3
Answer: [tex]C(t) = 120(1-0.30)^t[/tex]
Step-by-step explanation:
Exponential equation for decay:[tex]y= A(1-r)^t[/tex], where A = initial value, r= decay rate , t= time.
As per given, A = 120ml , r= 0.30
[tex]C(t) = 120(1-0.30)^t[/tex]
Hence, the required function that gives the medicine's concentration in milligrams per liter, C(t), t hours after the medicine was injected.
[tex]C(t) = 120(1-0.30)^t[/tex]

Answer:
45 3/10 miles per hour
Step-by-step explanation:
Distance travelled by the car = 30 1/5 miles
Time taken = 2/3 of an hour
Average speed = distance travelled / time taken
= 30 1/5 miles ÷ 2/3 of an hour
= 151/5 ÷ 2/3
= 151/5 × 3/2
= (151 * 3) / (5 * 2)
= 453 / 10
= 45 3/10 miles per hour
Average speed = 45 3/10 miles per hour

Question Continuation :
1.construct a table for the sample space of the random experiment.
2.using the sample space find the probability that the total score of the two dice is:
a. greater than or equal to 5
b. greater than 5 but less than 8.
Answer:
See belowStep-by-step explanation:
#5
P(man) = 8/15P(lady) = 7/15(a)
P(both ladies) = 7/15*6/14 = 1/5(b)
P(both men) = 8/15*7/14 = 4/15(c)
P(same sex) = P(both men or both ladies) = 1/5 + 4/15 = 7/15(d)
P(different sexes) = P(man and lady or lady and man) = 8/15*7/14 + 7/15*8/14 = 8/15Another way:
P(different sexes) = 1 - P(both ladies) - P(both men) = 1 - 1/5 - 4/15 = 8/15#6

b
b-6
0
Answer:
b = v
Step-by-step explanation:
3b = 6v – 3b
Add 3b to each side
3b+3b = 6v – 3b+3b
6b = 6v
Divide by 6
6b/6 = 6v/6
b = v

Answer:
m∠6 = 110°
Step-by-step explanation:
∠6 and ∠8 are known as corresponding angles meaning they are equal to each other. Since m∠8 = 110°, m∠6 also equals 110°.
Answer:
11o degree
Step-by-step explanation:
angle 6 is 110 degree because the relation between angle 6 and angle 8 is that they are corresponding angles and corresponding angles are always equal.
