Find an equation in point-slope form for the line having the slope m= - 4 and containing the point (4,5).
The equation in point-slope form is
(Use integers or fractions for any numbers in the equation.)
Answers
Step-by-step explanation:
The point-slope form of a line is (y - y₁) = m(x - x₁)
Since we know the slope (m) is -4
And the point ( x₁, y₁ ) is (4, 5)
Then we can just plug these into the equation above:
⇒ y - 5 = - 4 (x - 4)
I often use Desmos to check my answer. As seen below, the equation does pass through the point (4, 5).

of the bill was for labor costs. How much was the total bill if the cost of the labor was $79.50? Let b = the amount of the total bill.
Which equation and solution is correct?
Five-thirds b = 79.50, and the total bill was $47.70.
Three-fifths (79.50) = b, and the total bill was $127.20.
Five-thirds b = 79.50, and the total bill was $212.00.
Three-fifths (b) = 79.50, and the total bill was $132.50.
Answers
Answer:
132.50
Step-by-step explanation:
3/5b = 79.50
b = (79.50) / (3/5)
b = 79.50 * 5/3
b = 397.50/3
b = 132.50
132.50 is the total bill

r=35/25
r=1.4
substitution
r160=t*15
t=time
r=1.4

It took a car 2 days to travel 2274 miles. What was this car's average speed, in miles per hour? (round to the nearest mile per hour)
Answers
Answer:
47 mph
Step-by-step explanation:
1 day = 24 hours, so 2 days = 48 hours.
2274/48 (2274 miles per 48 hours, simplify!) This equals 47.375. Round it down to 47 mph.
This is assuming the car took no breaks.

22. Write the word sentence as an equation. The product of negative 2 and 5 plus a number d = 14.
also please solve and "product" means multiply.
Answers
-2 * 5 + d = 14
Solving by multiplying -2 and 5 first:
-10 + d = 14
Add 10 to both sides to get rid of the negative 10:
-10 + d + 10 = 14 + 10
-10 plus 10 gives 0 and it cancels out so:
d = 24 is the solution.

What is the slope of this line?
a. -1/3
b. 1/3
c. 2/3
d. -2/3
Answers
Answer:
c. 2/3
Step-by-step explanation:
Since the line is going up to the right it is a positive slope. Therefore it can't be a or d.
The slope is 2/3 because to connect the dots you have to go up 2 and to the right 3.

Put the following equation of a one into a slope -intercept form, simplifying all fractions.
8x+6y=-54
Answers
Answer:
y = -4/3x -9
Step-by-step explanation:
Slope intercept form is
y = mx+b where m is the slope and b is the y intercept
8x+6y = -54
Subtract 8x from each side
8x+6y-8x = -8x-54
6y = -8x-54
Divide each side by 6
6y/6 = -8x/6 -54/6
y = -4/3x -9
Answer:
y = -4/3x - 9
Step-by-step explanation:
Putting this into 'y=mx+c' form:
i) Firstly, make it only y on the LHS:
6y = -8x-54
ii) Secondly, making the 'y' have a co-efficient of 1. This can be done by dividing both sides by 6:
6y/6 = -8x/6 - 54/6
y = -4/3x - 9
Hence,
y = -4/3x - 9

5x+4=5x+4 is it one solution, no solution, or infinite solutions?
Answers
Simplifying
5x + 4 = 5x + 4
Reorder the terms:
4 + 5x = 5x + 4
Reorder the terms:
4 + 5x = 4 + 5x
Add '-4' to each side of the equation.
4 + -4 + 5x = 4 + -4 + 5x
Combine like terms: 4 + -4 = 0
0 + 5x = 4 + -4 + 5x
5x = 4 + -4 + 5x
Combine like terms: 4 + -4 = 0
5x = 0 + 5x
5x = 5x
Add '-5x' to each side of the equation.
5x + -5x = 5x + -5x
Combine like terms: 5x + -5x = 0
0 = 5x + -5x
Combine like terms: 5x + -5x = 0
0 = 0
Solving
0 = 0
Couldn't find a variable to solve for.
This equation is an identity, all real numbers are solutions.
Infinite solutions
Try to solve this equation:
5x+4=5x+4
Move all the variables to the left:
5x-5x+4=4
Do you see what I see?
4=4
We end up with a true statement. 4 does indeed equal 4. Hope this helps!

Hi there!
∠SRQ = 162°
∠STR = 130°
∠RST = ?
Now;
∠SRQ = ∠RST+∠STR [external angle is equal to the sum of opposite interior angles of triangle]
∠RST = ∠SRQ-∠STR
∠RST = 162°-130°
Therefore, the measure of ∠RST is 32°.
