9x^2+21x-8=0
Answer:
(3 x - 1) (3 x + 8)
Step-by-step explanation:
Factor the following:
9 x^2 + 21 x - 8
Factor the quadratic 9 x^2 + 21 x - 8. The coefficient of x^2 is 9 and the constant term is -8. The product of 9 and -8 is -72. The factors of -72 which sum to 21 are -3 and 24. So 9 x^2 + 21 x - 8 = 9 x^2 + 24 x - 3 x - 8 = 8 (3 x - 1) + 3 x (3 x - 1):
8 (3 x - 1) + 3 x (3 x - 1)
Factor 3 x - 1 from 8 (3 x - 1) + 3 x (3 x - 1):
Answer: (3 x - 1) (3 x + 8)

Suppose a friend asks you which of the two plans is less expensive. How would you respond? (Answer specificly please)
Answer: I think Plan A is the cheapest
Step-by-step explanation:
I would say this because all it is is a 10 cent incline and 30 dollars cheaper, meaning it would take almost 15 weeks to earn 30 dollars on the plan a, while plan b will already be at like 100 Dollars.

Approximate the solution to the graphed system. Explain how you got your answer.
Answer:
(7.5, 12)Step-by-step explanation:
The solution of a linear system is the intersection of the lines.
We can see the lines A and B intersect at the point (7.5, 12) which is the solution.
See attached for better visualization.
Answer:
(7.5,12.5)
Step-by-step explanation:
See the intersected point is almost situated at the middle of 10 and 15 .Hence its 12.5 on y.And the point is situated in the middle of 7 and 8 .Hence its 7.5 on x. Your school
band needs to buy new percussion
equipment. The equipment will
cost $2450. You have collected
$812 in previous fundraisers. If
you sell sandwiches at $3.50 each,
how many sandwiches will you
need to sell to raise the remaining
funds?
Answer: 468 sandwiches
Step-by-step explanation:
subtract 812 from 2450. you're left with 1,638 dollars left.
divide 1638 by 3.5 and you get 468
so the question says im at dicks looking for new balls for the team because the ones we have are deflated and it cost $56 per each ball if i have $198.98 how many balls will i be able to but at the dicks store
Answer:
3
Step-by-step explanation:
We cannot but partial balls so we need whole number of balls.
we can use units to easily visualze the issue.
56 $/ball and we have $198.98. We need balls so we do
198.98 / 56 = 3.55
We can at most buy 3 balls.
EXTRA: 56 * 3 = 168
will have 30.98 leftover
Answer:
The answer is 6
Step-by-step explanation:
You can buy 6 balls.

13,215; 5,468.
What is the median
depth?
Answer:
12,880
Step-by-step explanation:
You put them in least to greatest and then take one off each end, like the smallest and largest go first(5,468 and 13,215). The median is the one left in the middle and there can be more than one, but in this case there is only one and it is 12,880.

Answer: 56
Step-by-step explanation:

Lets rewrite it
When you have two terms next to each other, it means multiply.
Therefore, we can rewrite this as
(14) x (4)
y times z
14 x 4 = 56

find three consecutive even intergers such that the sum of the smallest number and twice the middle number is 20 more than the largest number
Answer:
10, 12, 14
Step-by-step explanation:
Hi there!
Let x be equal to the smallest integer.
Let (x+2) be equal to the next even integer.
Let (x+4) be equal to the largest even integer out of the three.
We're given:
⇒ smallest number + (2 × middle number) = 20 + largest number
Construct an equation:
[tex]x+2(x+2)=20+(x+4)[/tex]
Combine like terms:
[tex]x+2x+4=20+x+4\\3x+4=x+24\\2x=20\\x=10[/tex]
Therefore, the smallest integer is 10, making the next two even integers 12 and 14.
I hope this helps!

−3/5−4/5=
Answer:
-7/5.
Step-by-step explanation:
Leave the denominators the same and subtract only the numerators. Since -3 is negative and 4 is a positive being subtracted, you get -7 as the numerator. So, it's -7/5.
what is the quotation of 9÷1/2
Answer:
18
Step-by-step explanation:
9 ÷ [tex]\frac{1}{2}[/tex]

Line CD passes through points C(1, 3) and D(4, -3). If the equation of the line is written in slope-intercept form, y =mx + b, what is the value of b?
0-5
0 -2
0 1
O 5
Answer:
5
Step-by-step explanation:
In the slope- intercept form of y= mx +b, m is the slope and b is the y- intercept.
Let's find the slope using the formula below:
[tex]\boxed{slope = \frac{y1 - y2}{x1 -x 2} }[/tex]
[tex]m = \frac{3 - ( - 3)}{1 - 4} [/tex]
[tex] m = \frac{3 + 3}{ - 3} [/tex]
[tex]m = \frac{6}{ - 3} [/tex]
m= -2
Substitute m= -2 into the equation:
y= -2x +b
To find the value of b, substitute a pair of coordinates into the equation:
When x= 1, y= 3,
3= -2(1) +b
3= -2 +b
b= 3 +2 (+2 on both sides)
b= 5
Thus, the 4th option is correct.

Step-by-step explanation:
let x represent the equally priced bracelets of which there are 4 , so 4x
We know she spent $64 on rings and a total of $200 was spent , then
64 + 4x = 200 ← represents the situation
x represents the cost of a bracelet
Answer:
c
Step-by-step explanation:
the total amount paid at the jewelry is 200
64 was spent on rings
the rest amount of money was spent on 4 bracelets
let the price of one bracelet be x
200=4(x)+64
200=4x+64
