Answer:
x=5 and x=-5
Step-by-step explanation:
1. first you would subtract 6 from both sides to set the equation = to zero.
2. The equation would then be x^2-25=0.
3. that is a difference of two squares polynomial. So when you factor it, it is (x+5)(x-5)=0
4. by the zero product property, the roots are 5 and -5.

A bag contains pennies, nickels, dimes, and quarters. There are 50 coins in all. Of the coins, 18% are pennies and 36% are dimes. There are 2 more nickels than pennies. How much money does the bag contain?
Answer: $5.44
Step-by-step explanation:
18% of 50= 9 pennies
36% of 50= 18 dimes
9 + 2= 11 nickels
9+18+11= 38 pennies, nickels and dimes.
50 (total amount of coins) - 38 (pennies nickels and dimes)= 12 quarters.
9 pennies= 9 cents
18 dimes= 180 cents
11 nickels= 55 cents
12 quarters= 300 cents
9 + 180 + 55 + 300= 544 cents= $5.44
Answer:
$5.44
The bag contains $5.44.
Step-by-step explanation:
Pennies:
50(18/100)= 9 pennies
Dimes:
50(36/100)= 18 dimes
Nickels:
2 more nickels than pennies
9+2= 11
Quarters:
9+18+11= 38
50-38= 12 quarters
1 penny = 0.01 dollar
9x0.01= 0.09
1 dime = 0.10 dollar
18x0.10= 1.80
1 nickel = 0.05 dollar
11x0.05= 0.55
1 quarter = 0.25 dollar
12x0.25= 3
0.09+1.80+0.55+3= $5.44
please answer the question.
10(1+3d)=-20
step by step pls
Answer:
d=-1
Step-by-step explanation:
10(1+3d)= -20
divide both sides by 10
1+3d=-2
move the costant to the right, change the sign
3d=-2-1
caclulate
3d=-3
divide both sides by 3
d=-1
Simplify
2x +3 (4x – 8) + 10
Hope it helps you....

Decide whether or not it is a function.
Answer:
Step-by-step explanation:
Yes it's a function.
You may be looking at v which produces m
You may be looking at r which also produces m.
That's fine. Two different x values (the domain) can produce the same y value. Lots of functions do that. (you'll study parabolas pretty soon and all that open up or down have two x values producing the same y value).
If you have a member of the domain producing 2 y values, that doesn't work. That would not be a function.
This example is a function.

4. In triangle ABC, AC=11,BC=24, and m
a. 40
b. 46.3
c. 20.5
d. 23.7
Answer:
23.7°
Step-by-step explanation:
To obtain the value of AB ; Use the cosine rule ;
Recall:
c² = a² + b² - 2ab Cos C
c² = 24² + 11² - 2*24*11 Cos75
c² = 576 + 121 - 528 * 0.2588190
c² = 697 - 136.656432
c² = 560.343568
c = sqrt(560.343568)
c = 23.6715
Hence, c = AB = 23.7°

Hey can u help with the following questions because I don't get this.
Answer:
median- 58.5
first quartile- 56
third quartile- 65
interquartile range- 9
Step-by-step explanation:
median is when you put the numbers from least to greated and find the middle number; so, you will put this set in that order= 38, 46, 55,56,58,59,61,65,67,75. now, you get stuck between 58 and 59. so you add them and divide by two to get 58.5. thats the median. The first quartile is any number from the set that is smaller than the median, basically the first half of it. now you will just find the median of that which is 56. that is your first quartile. third quartile is the second half of the set, any number in the set that is greater than the median. you will find the median of that half to get 65. that is your 3rd quartile. interquartile range ius the difference bewteen your first and third quartile. 65-56 is 9. hope this helped marck as brainlyest and help me with my que tooo :)

Answer:
Y=-6x
Step-by-step explanation:
Choose two points from the graph (0,0) and (1,-6)
Average Rate of Change= (y2-y1)/(x2-x1)
(-6-0)/(1-0)=-6/1=-6
y=-6x+b
0=-6(0)+b
0=0+b
0=b
Y=-6x+0
Y=-6x
Can anyone help me out on this
Answer:
y=x+10
Step-by-step explanation:
y=mx+b
y=1x+b
1 because for every 10 it goes to the right, it goes up 10 as well.
b=10 because the function crosses the y-axis at 10
so
y=x+10
