What is the point-slope form of a line that has a slope of 5 and passes through the point (3, –4)?
y – 3 = 5[x – (–4)]
–4 – y1 = 5(3 – x1)
y – (–4) = 3(x – 5)
y – (–4) = 5(x – 3)
Answer:
The answer is: y - (-4)= 5(x-3)
Point slope form is:
y-y1=m(x-x1)
m is your slope. They tell us the slope is 5. They also give you an ordered pair. Substitute this ordered pair into the point slope equation for the x1 and y1 values.

Answer:
There are no solutions
Step-by-step explanation:
Every solution is going to equal 6 instead of the designated 12.
For example if x equals 26:
6 x 26 = 156 + 2 = 158
Y = 158
3 x 158 = 474
18 x 26 = 468

Please help me!!!!!!
Answer:
The third one is the correct answer .
Because the x's don't have more than 1 y value .
All the other tables do, which makes those not a function, but since the third one has 1 x value for 1 y value, then it is a function.
Answer:
It's the second to the top one
Step-by-step explanation:
because the positive y numbers correspond to a negative x 2 and vice versa

Answer:
is there a visual version of this question?
Answer:
x + y = 180 Fact about angles and parallel lines.
x - y = 35 Given
Solution
Add the equations together
2x = 180 + 35 Combine
2x = 215 Divide by 2
2x/2 = 215/2 Divide
x = 107.5
The larger angle is 107.5
The smaller angle is 180 - 107.5 = 72.5

Janice wants to invest $1,000. Texas Loan & Credit will offer Janice an annual simple interest rate of 6% that is paid upon withdrawal. Pecan & Cedar Savings Bank will offer Janice an interest rate of 3% that is compounded annually. Which Bank will yield better interest earnings after investing $1,000 for 2 years?
Answer:
Texas Loan & Credit will yield better interest earnings after Janice invested $1,000 for 2 years.
The interest earnings will be $120 as against Pecan & Cedar's $60.90.
Explanation:
Texas Loan & Credit:
Simple interest rate = 6%
Janice's Investment = $1,000
Interest earnings = $120 ($1,000 * 6% * 2)
Pecan & Cedar Savings Bank:
Compound interest rate = 3%
Janice's investment = $1,000
Interest earnings = $60.90 ($1,000 * 3%) + ($1,030 * 3%)
In the second year, the interest earnings of $30 are added to the principal to get a new compounded principal of $1,030 on which 3% is also applied.

The credit remaining on a phone card (in dollars) is a liner function of the total calling time made with the card (in minutes) the remaining credit after 30 minutes of calls is $15.20 of the remaining credit after 46 minutes of the call is $12.64 what is the remaining credit after 54 minutes of calls?
Answer:
$11.36 (11 dollars and 36 cents).
Step-by-step explanation:
This scenario can be written as the linear equation: y = -$0.16x + $20 Where y is the remaining credit, and x is the minutes spend calling.
To find the remaining credit after 54 minutes,
substitute 54 for x and simplify.
So y = -$0.16(54) + $19.60 = -$8.64 + $20.00 =
$20.00 - $8.64 = $11.36.
_________________________
If you want to solve this problem from scratch, first find the constant rate of money by subtracting 30 minutes (time) over $15.20(total) by 46 minutes over $12.64(total).
Just subtract across, and simplify to get the rate, and then apply that rate between the missing total of 54 minutes and the total of $12.64 dollars for 46 minutes. This is because rate = change quantity/change in time. If that rate is constant as it is in this relationship where the quantity is the amount of anything that is dependent on something, in this case it's money.
So subtract (find the difference) to find the pattern of change between these values in respect to time.
15.20/ 30 - 12.64 / 46 = 2.56 / -16 = 1.28 / -8 = 0.64 / -4 = 0.32 / -2 = 0.16 / -1 = -0.16 [This is the rate decrease in money every minute of a call being made or decrease in remaining credit every minute ].
Now since we know the rate, we can solve the missing factor of the problem by multiplying the rate by the change in time to get the change in quantity.
So : 54 - 46 = 8. 8 × 0.16 = 1.28 [This is the change in quantity from 46 to 54 minutes of calling ].
Therefore, $12.64 [remaining credit from 46 minutes ] - $1.28 [the change of credit from 46 minutes to 54] = $11.36 [remaining credit from 54 minutes].
Also in general, Rate = dependent variable / independent variable.

What method can be used to prove the triangles below are congruent
Answer:
SSS?Step-by-step explanation:
I don't know why the answers don't offer this an option. However, the side that shares both triangles must be congruent to itself and the other highlighted congruent parts are sides, not angles. Therefore by my calculations, the answer has to be SSS, but this isn't a choice.

A. 4
B. 0
C. 2
D. -7
Answer: D
Step-by-step explanation: -7 is not included in the shaded part of the inequality
Answer:
Step-by-step explanation:
-2w-7.25<-3.25 add 7.25 to both sides
-2w< 4 divide by -2
w< -2
W has to be smaller than -2
The smaller than -2 is -7. So all the others are not.

Answer:
The largest side of given triangle is: AB
Step-by-step explanation:
In order to find the largest side, we have to find all the triangles first.
The two angles at point A will sum up to 180° as the angles on the straight line are supplementary.
So,
[tex]136 + Angle\ A = 180\\Angle\ A = 180-136 = 44[/tex]
∠A = 44°
∠C = 71°
The sum of interior angles of a triangle is 180°
Using this:
∠A+∠B+∠C = 180°
44°+∠B+71° = 180°
∠B+115° = 180°
∠B = 180°-115°
∠B = 65°
In a triangle, the side opposite to the largest angle is the largest. In the given triangle, ∠C is the largest so the side AB which is opposite to ∠C is the largest.
Hence,
The largest side of given triangle is: AB

x > 10/3
x will always be greater that 10/3 never the same nor less.
Step-by-step explanation:
3/5x + 1/3 < 4/5x - 1/3
3/5x - 4/5x + 1/3 < -1/3
-1/5x + 1/3 < -1/3
-1/5x < -1/3 - 1/3
-1/5x < -2/3
-1/5x/-1 < -2/3/-1 (Since it is both divided by a negative the sign switches, the sign also switches with multiplication. *Note: it only switches if it is negative!*)
1/5x > 2/3
5 • 1/5x > 2/3 • 5
x > 2/3 • 5/1
x > 10/3
