Answer:
Step-by-step explanation:
Let x be the amount invested at 9%.
Then the amount invested at 6.5% is 1240-x dollars.
From the condition, you have this equation
0.09x = 0.065*(1240-x).
x=520

Find the gradient and y-intercept in this equation:
[tex]8x+2y+9=0[/tex]
Answer:
Gradient: -4
y-intercept: [tex]-\frac{9}{2}[/tex]
Step-by-step explanation:
Step 1 - Subtract 8x from both sides to isolate the 2y + 9
[tex]8x + 2y + 9 = 0\\8x + 2y + 9 - 8x = 0 - 8x\\2y + 9 = -8x\\[/tex]
Step 2 - Subtract 9 from both sides to isolate the 2y:
[tex]2y + 9 = -8x\\2y + 9 - 9 = -8x - 9\\2y = -8x - 9[/tex]
Step 3 - Divide both sides of the equation by 2:
[tex]\frac{2y}{2} = \frac{-8x}{2} - \frac{9}{2}\\y = -4x - \frac{9}{2}[/tex]
In this form, y = mx + b, the m value is the gradient with the b value being the y-intercept. This means:
[tex]y = -4x - \frac{9}{2}\\\\m = -4\\b = -\frac{9}{2} \\\\[/tex]
Resulting in the gradient being -4 and the y-intercept being [tex]-\frac{9}{2}[/tex].
Hope this helps!

IM DESPERATE FOR AN ANSWER Customers of a phone company can choose between two service plans for long distance calls. The first plan has an $18 monthly fee and charges an additional $0.13 for each minute of calls. The second plan has no monthly fee but charges $0.17 for each minute of calls. For how many minutes of calls will the costs of the two plans be equal?
Answer:
450 minutes
Step-by-step explanation:
1st plan
18 + 0.13x = y
2nd plan
0.17x = y
x is minute of calls
y is the total price customers must pay
both of them equal as y = y
y = y
18 + 0.13x = 0.17x
18 = 0.17x - 0.13x
18 = 0.04x
x = 18/0.04
x = 450 minutes
can you figure how much they should pay?

The number of hours, h, that Mr. Hampton works varies directly with the number of tasks, t, he has to perform. If he has 6 tasks to perform and works for 15 hours, what is k the constant of variation?
i think its 2.5 because 15/6= 2.5 so 2.5t=h and the equation is kt=h so 2.5 makes the most sense.

7) What is the SECOND step in simplifying the equation below?
4 - 3y = 31
Answer:
subtract 4 from both sides
Step-by-step explanation:
you will then get -3y=27 as your equation then you just divide each side by -3 and your answer will be y = -9
Answer:
Step-by-step explanation:
4 - 3y = 31
Step 1: Subtract 4 from both sides
-3y = 31 -4
-3y = 27
Step 2: Divide both sides by (-3)
[tex]\dfrac{-3y}{-3}=\dfrac{27}{-3}[/tex]
y = -9
A grocer can buy strawberries for $1.38 per pound
The order of strawberries cost $241.50. How many pounds did the grocer order?
I know the answer is 175 I just don’t know how to explain how I got it
Work Shown:
x = number of pounds of strawberries purchased
1.38x = cost of buying those x pounds of strawberries, at $1.38 a pound
1.38x = 241.50
x = (241.50)/(1.38)
x = 175
As a check,
1.38*x = 1.38*175 = 241.50
which confirms the answer

1) Through any two points, there is exactly one line.- postulate
2) A line segment is a part of a line and is bounded by two endpoint. - Definition
3) If two lines intersect, then each pair of opposite angles are congruent. - Theorem
What are postulates?"These are statements that are assumed to be true without proof."
What is definition?"It is used to give a precise meaning to a new term."
What is theorem?"It is a statement that can be proved to be true by accepted mathematical operations and arguments"
For given question,
We have been given three statements.
We need to classify them as theorem, postulate and definition.
The first statement is 'Through any two points, there is exactly one line.'
We know that this is the fundamental postulate use in Geometry.
The second statement is 'A line segment is a part of a line and is bounded by two endpoint.'
Above statement is the definition of line segment.
The last statement is 'If two lines intersect, then each pair of opposite angles are congruent.'
We can prove above statement by using Euclid's axiom.
So, above statement is a theorem.
Therefore, 1) Through any two points, there is exactly one line.' - postulate
2) A line segment is a part of a line and is bounded by two endpoint. - Definition
3) If two lines intersect, then each pair of opposite angles are congruent. - Theorem

Graph the following equation: y = -5x + 1
Answer: in your graphplot the point of the y-intercept(which in this case is 1, hence the “+1”)
Step-by-step explanation:
Next 5x is the same as -5/+1 which pretty much means you have to go down 5 times and 1 to the right in a repeated motion until you can no longer plot that point.
then you do the opposite of -5x which is -1/+5 which means you have to go up 5 times and 1 to the left in a repeated motion until you can’t
