Answer:
3x2+15x=18
Step 1: Subtract 18 from both sides.
3x2+15x−18=18−18
3x2+15x−18=0
Step 2: Factor left side of equation.
3(x−1)(x+6)=0
Step 3: Set factors equal to 0.
x−1=0 or x+6=0
x=1 or x=−6

I worked them out myself so if their wrong uh please don't get mad I tried my best.
Step-by-step explanation:
3x (2) + 15x = 18 3x (2) + 15x = 18
6x + 15x = 18 6x + 15x = 18
-6x + -6x = 18 -18 -18
-------------------------- ------------------------
0 + 9x = 18 6x + -3 = 0
------ ------- -3 + -3
18 18 --------------------
x = 2 -3 + 0
X = -3

Adam bought a baseball bat and a baseball. He paid $ 1.10 for two of them. The baseball bat cost $ 1 more than a ball. What are the prices of these items?
Answers
Answer:
0.05
Step-by-step explanation:
Lets consider that cost of bat is 'x' and cost of baseball is 'y'.
Therefore, according to the question
x + y = $1.10
And the cost of bat is one dollar more than that of baseball, therefore -
x - y = $1.00
Now let us add these two equations, which will cancel out 'y' i.e, cost of baseball
=> 2x = $2.10
=> x = $1.05
Thus the cost of bat is $1.05
Now substitute this value of x in any equation...lets consider in first equation
=> 1.05 + y= 1.10
=> y = $0.05
Therefore the cost of baseball is $0.05.

Mary’s annual salary is $38,500 plus 22% in employee benefits. Her yearly job expenses are: uniforms, $500; transportation and parking, $5,350; and tools and certifications, $1,200. What are her net job benefits?
Answers
Answer: $39,920
Step-by-step explanation:
Her net job benefits would be the benefits and salary she receives less the expenses she incurs in relation to the job:
= Salary + Benefits - Uniforms - Transport - Tools
= 38,500 + (22% * 38,500) - 500 - 5,350 - 1,200
= 46,970 - 7,050
= $39,920

Can you guys find the slope and y-intercept
Answers
Answer:
Step-by-step explanation:
Plot any tow points on the line and find the slope
(-1 , 3) ; ( -2 , 1)
Slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]= \frac{1-3}{-2-[-1]}\\\\= \frac{-2}{-2+1}\\\\=\frac{-2}{-1}\\\\=2[/tex]
m = 2 ; (-1 , 3)
y - y1 = m(x - x1)
y - 3 = 2*(x - [-1])
y - 3 = 2*(x + 1)
y -3 = 2*x + 2*1
y -3 = 2x + 2
y = 2x + 2 + 3
y = 2x + 5
Slope = 2
y-intercept = 5

Answer:
Move the terms with a to one side
3a-2a =-6

a=-6
Answer:
[tex]a = - 6[/tex]
Step-by-step explanation:
1) Subtract 3a from both sides.
[tex]6 = 2a - 3a[/tex]
2) Simplify 2a - 3a to -a.
[tex]6 = - a[/tex]
3) Multiply both sides by -1.
[tex] - 6 = a[/tex]
4) Switch sides.
[tex]a = - 6[/tex]
So, therefor, the answer is, a = -6.

$100 invested at 11% compounded quarterly after a period of 3 years
Answers
Answer:
$138.27.
Step-by-step explanation:
Given that it is required to obtain the amount of money that arises from $ 100 invested at 11% compounded quarterly after a period of 3 years, to determine said amount the following calculation must be performed:
X = 100 x (1 + 0.11 / 3) ^ 3x3
X = 100 x (1 + 0.03666) ^ 9
X = 100 x 1.03666 ^ 9
X = 100 x 1.3827
X = 138.27
Thus, the amount that will arise from said investment is $ 138.27.

charlie runs laps around a track. the table shows how long it takes him to run different numbers of laps. how long would it take charile tto run 5 laps laps-2,4,6,8,10 time-6,12,18,24,30
pls help

Answer:
25 minutes
Step-by-step explanation:
From the table,
2 laps takes time 10 min.
4 laps takes time 20 min.
6 laps takes time 30 min.
8 laps takes time 40 min.
10 laps takes time 50 min.
So, we can deduce the relation between the number of laps and time
the time over the number of laps at each row = 5
Which mean 1 lap takes 5 minutes
sooooooo, to run 5 laps, it takes = 5 * 5 = 25 minutes

Answers
Answer:
If Kristen were to make 4 batches, and each batch requires 2 cups of flour, how many cups of flour would she need? To solve this question, we would just multiply 4 by 2, which gives us a final product of 8.
Similarly, in this question, if one batch requires 1 3/4 cups of flour and Kristen wants to bake 3 1/2 batches, she would need 1 3/4 x 3 1/2 cups of flour.
1 3/4 can be rewritten as an improper fraction- 7/4.
3 1/2 can also be rewritten as an improper fraction- 7/2.
Multiplying 7/4 and 7/2, we obtain a final product of 49/8, or 6 1/8.
This means, Kristen will need 6 1/8 cups of flour to make 3 1/2 batches, and her belief that she needs 3 3/8 cups of flour is wrong, as she needs a lot more than that.
Hope this helps!
Answer:
no she is incorrect
she will require 49/8 cups
