Answer:
Below
Step-by-step explanation:
Given Data:
The sum of two numbers is less than 2If we subtract the second number from the first , the difference is greater than 1Q) What are the two numbers?
Lets suppose the first number to be x and the second number to be y
The first point states sum of two number which is x + y is less than 2 so our first expression becomes,
[tex]x+y<2[/tex]
The second point states that the if we subtract the second number from the first number which states x - y the difference is greater than 1 so our second expression becomes,
[tex]x-y<1[/tex]
1) The riddle can be represented by a system of inequalities. Write an inequality for each statement.
The inequality for the first statement is
[tex]x+y<2[/tex]
The inequality for the second statement is
[tex]x-y>1\\[/tex]
I assume the second part to the question would be solve for x and y xD
so here goes
2)
If we just simply add both the equations we get the following result:
[tex]x+x+y-y=2+1[/tex]
Just suppose there is an equal to sign instead of less than or greater than
[tex]x+x+y-y=2+1\\2x+0=3\\x=3/2\\x=1.5\\[/tex]
now put the value of x in any one of the two equations I choose equation 1
[tex]x+y=2\\1.5+y=2\\y=2-1.5\\y=0.5[/tex]
I attached an image so you can understand it better :)
2t+8=10 solve the equation
Answer:
t = 1
Step-by-step explanation:
2t + 8 = 10
2t = 2 (-8 on both sides)
t = 1 (divide 2 on both sides)
Answer:
t = 1

Step 2: Solve for t
Subtract 8 on both sides: 2t = 2Divide 2 on both sides: t = 1How do you convert 18,420.15427 into money form?
Find the slope of the line 6x + 5y = -5
Answer:
Using the y=mx+b formula: -6/5
Step-by-step explanation:
6x + 5y = -5
5y = -6x -5
y = -6/5x -1
The slope would be -6/5, meaning the line would travel 5 to the right and 6 down, starting from the coordinate 0, -1.

You might keep your money in a bank, but have you heard of a time
bank? This online service allows users to trade
services with one
another without exchanging money. For example, a hairdresser gives
someone a haircut for one hour of credit in the time bank. The
hairdresser could then use that credit to have a plumber come work for
her for an hour. Time banks are useful for people who can't arrange
direct trades. The plumber might not want a haircut, but he can work
for the hairdresser and earn credit to use with someone else.
How does the detail "The plumber might not want a haircut, but he can work
for the hairdresser and earn credit to use with someone else" best support
the central idea that time banks are a convenient way to get things done?
Explanation:
Of course, the plumber might not want a haircut, but he might have a wife, a fiancee, or a sister who may need the services of a hairdresser so working for the hairdresser would earn him credit that can be used by any of these people. So in a sense, he is getting things done for others.
Therefore, the time-bank service solves a problem by allowing people to receive services without exchanging money.
Joshua babysits for his sister after school. He is paid
$3.00 for each hour of babysitting. He has saved $43.50
and wants to buy a toy that costs $70. What is the least
amount of hours Josh needs to babysit to purchase the
toy?
Plz help
Answer:
9 hrs
Step-by-step explanation:
Joshua has already saved $43.50 so you subtract $43.50 from 70 which leaves you with $26.50. Joshua still needs $26.50.
$26.50 divided by $3 per hr is 8.833 repeating. Obviously you can’t work 8.833 hrs so you round it up to 9. So, Joshua has to work for at least 9 hrs more.
Hope this helps :)

I gave you two different answers for 2b.
Find the x-intercept and the y-intercept of the graph of the equation.
2x + 6y = 36
Answer:
(0,6), and (18,0)
Step-by-step explanation:
2x +6y = 36
6y = -2x +36
y =(-2/6) x+ 36/6
y=(-1/3)x +6
compare this equation to y=mx+b where b is the y-intercept so the
y-intercept is a point at (0, 6)
to find the x-intercept make the equation equal to 0
(-1/3)x+6=0 subtract 6 in both sides
(-1/3)x = -6 cross multiply
-x = 3*-6
x=18 so the
x-intercept is a point at (18,0)

the sum of 2 positive integers is 10. the difference of their reciprocals is 3/8. find both positive integers
Answer:
The 2 integers would be: 2 and 8
Step-by-step explanation:
2 + 8 = 10
Reciprocal of 2: 1/2
Reciprocal of 8: 1/8
1 / 2 - 1 / 8 = 4/8 - 1/8 = 3/8

In a certain sequence, each term, starting with the 3rd term, is found by multiplying the previous two terms. What is the difference between the 6th and 3rd terms in the sequence
Answer:
-3
Step-by-step explanation:
Let the first term be a-d, second term be a and third term be a+d
d is the common difference
If each term, starting with the 3rd term, is found by multiplying the previous two terms then:
a(a-d) = a+d
a²+ad-a-d = 0
a(a+d)-1(a+d) = 0
(a+d)(a-1) = 0
a-1 = 0
a= 1
a+d = 0
1+d = 0
d = 0-1
d = -1
Get the sixth term
nth term of a sequence is expressed as
Tn = a+(n-1)d
T6 = 1+(6-1)(-1)
T6 = 1+5(-1)
T6 = 1-5
T6 = -4
Get the third term T3
T3 = a+2d
T3 = 1+2(-1)
T3 = 1-2
T3 = -1
difference between the 6th and 3rd terms in the sequence is expressed as;
Difference = T6-T3
Difference = -4-(-1)
Difference = -4+1
Difference = -3
In a survey, 61 people were asked how much they spent on their child's last birthday gift. The results were roughly bell-shaped with a mean of $39 and standard deviation of $3. Find the margin of error for a 99% confidence level.
Answer:
0.989
Step-by-step explanation:
The formula for Margin of Error is:
z × Standard deviation/√n
Where
z = z score for 99% confidence Interval
= 2.576
n = 61 people
Standard deviation = $3
Hence,
Margin of Error
= 2.576 × 3/√61
= 0.989

Label the vertex of this function[tex]y=-3(x-1)(x+4)[/tex]:
Answer:
vertex = ( - [tex]\frac{3}{2}[/tex], [tex]\frac{75}{4}[/tex] )
Step-by-step explanation:
Given a parabola in standard form
y = ax² + bx + c ( a ≠ 0 )
Then the x- coordinate of the vertex is
[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]
Given
y = - 3(x - 1)(x + 4) ← expand the factors using FOIL
= - 3(x² + 3x - 4) ← distribute parenthesis by - 3
= - 3x² - 9x + 12 ← in standard form
with a = - 3 and b = - 9 , thus
[tex]x_{vertex}[/tex] = - [tex]\frac{-9}{-6}[/tex] = - [tex]\frac{3}{2}[/tex]
Substitute this value into the equation for corresponding value of y
y = - 3( - [tex]\frac{3}{2}[/tex] - 1)( - [tex]\frac{3}{2}[/tex] + 4)
= - 3 × - [tex]\frac{5}{2}[/tex] × [tex]\frac{5}{2}[/tex]
= - 3 × - [tex]\frac{25}{4}[/tex]
= [tex]\frac{75}{4}[/tex]
Thus
vertex = ( - [tex]\frac{3}{2}[/tex], [tex]\frac{75}{4}[/tex] )
