Answer:
A.) y=3x-1
Step-by-step explanation:
Point-slope form can be shown using the equation: y = mx+b
In this case, m is slope, and b is the y-intercept.
Slope in this graph can be found by finding the rise over the run, or the number of blocks the line moves vertically over the number of blocks the line moves horizontally. The line moves at a rate of 3 blocks up for every 1 block to the right, or 3/1. That means that the slope is 3.
The y-intercept is wherever the line crosses the y-intercept, or wherever x equals 0. This happens at y = -1.
If you plug the slope (3) and the y-intercept (-1) into the equation y = mx+b, you get y = 3x-1.

what is the area of a sector created by a circle with a radius of 4cm and a 40 central angle
Answer:
5.59 cm
Step-by-step explanation:
I had set up a proportion. The proportion is below.
360° 50.27
------- = ----------
40° ? (What you're trying to figure out)
So what I did was 50.27 times 40 which equals: 5.58555556, so I rounded it to 5.59 so that's your answer!
I hope that's helpful :D

Does every line have a slope and a y intercept?
Answer:
see below
Step-by-step explanation:
Not every line has a y intercept because vertical lines ( lines that go up and down) do not intersect the y axis
Does every line have slope? It depends on how you define slope
Vertical lines have a slope that is undefined. So they have a slope that is undefined. When you are asked what the slope of a vertical line is , you answer undefined
Answer:
no
Step-by-step explanation:
because the line can be 0

Answer:
the fourth answer choice
Step-by-step explanation:
Here we're dividing one fraction by another. To accomplish this, invert the divisor (the second) fraction and multiply instead:
4m^12 8m^3
------------ * ----------
x + 1 x^2
Multiplying the two numerators together results in 32 m^15. This matches the fourth answer choice.
If (x + y)^2 = 1 and xy = -4, what is the value of x^2 + y^2?
Answer:
[tex](x + y)^{2} = 1\\xy = -4\\x^{2} + y^{2} \\= x^{2} + 2xy + y^{2} - 2xy \\= (x^{2} + 2xy + y^{2}) - 2xy\\= (x+y)^{2} - 2xy\\= 1 - 2 *(-4) \\= 9[/tex]

Please help with this conditional probability question.
Answer:
8/45
Step-by-step explanation:
1. Since the dice has six sides and only two numbers are less than three (2 and 1) that means there is a 4/6 (2/3) chance of them rolling any other number besides 2 and 1. Since in bag two it has the yellow dice.
2. In bag two there are a total of 15 beads (4 yellow and 11 blue) since we want to get the yellow bead that means there is a 4/15 chance of getting a yellow bead.
3. Finally to find the chance of rolling a number greater than 2 and picking a yellow bead you must multiply the numerators and denominators. 2(4) and 3(15) which in turn equals 8/45.

A boat can travel with a speed of 13 km/hr in still water. If the speed of the stream is 4 km/hr, find the time taken by the boat to go 68 km downstream
Answer:
t=4h
Steps below
Step-by-step explanation:
We know:
speed of boat with respect to earth: 13 km
speed of stream with respect to earth: 4 km
13 km/h + 4 km/h = 17 km/h The time to travel 68 km with this speed is thus t = 68 km 17 km h = 4 h
Hope this helps.

If Candace made a scatter plot of the math scores of eighth-grade students (vertical scale) and their heights in inches (horizontal scale), what type of line of best fit should she expect the scatter plot show?
A. a line with positive slope
B. a line with negative slope
C. a horizontal line
D. There would be no line of best fit.
Answer:
The correct option is (D).
Step-by-step explanation:
A scatter plot is a mathematical graph used to display the linear relationship between two variables.
Points are plotted on the graph and a line of best is drawn to represent the linear relationship between the two variables.
If the line is upward moving this implies that there is positive relation between the variables.
If the line is downward moving this implies that there is negative relation between the variables.
If there is no line of best fit that can be formed using the data provided then this implies that there is no linear relationship between the variables.
The variables math-score and height of the students has no relation between them. This is because the height of a student does not factor the score he/she received in their math exam.
So, the scatter plot for this data will not have a line of best fit.
Thus, the correct option is (D).

Answer:
y = -3x + 3
Step-by-step explanation:
If ... A line has a slope of -3 and a y-intercept of 3, then the equation of that line is y = mx + b => y = -3x + 3. You don't need the table of values.
PLZZZZ I NEEED HELP!!!
I said please
Step-by-step explanation:
Angle 128 ° + Angle Y = 180 °
Y = 180 - 128
= 52 °
5x + 3 + Y = 180
5x + 3 + 52 = 180
5x + 55 = 180
5x = 180 - 55
5x = 125 °
x = 125 ÷ 5
x = 25

In the NBA, any shot made from 22 feet or more from the basket is worth 3 points. How many yards from the basket is that?
Answer:
22/3 yards, roughly 7.33 yards.
Step-by-step explanation:
We know that there is 3 feet in 1 yard.
Given 22 feet, we divide by 3 to find the amount of yards, thus changing the unit.
The exact amount of yards is just 22/3, which you can estimate to 7.33 yds.

Find the perimeter of a regular hexagon with a side of 8 meters
Answer:
8 x 6 = 48
Step-by-step explanation:
Hexagon = 6 sides
8 x 6 = 48
Answer:
48 meters
Step-by-step explanation:
A regular hexagon has six sides, all six sides are the same length. So you have to add 8 meters six times. Or just multiply 6 by 8. So you get 48 meters.
Solve –3d + 5 = 14.
–57
12
–27
–3
Answer:
d = -3
Step-by-step explanation:
–3d + 5 = 14.
Subtract 5 from each side
–3d + 5-5 = 14-5
-3d = 9
Divide each side by -3
-3d/ -3 = 9/-3
d = -3
Answer:
[tex]d = - 3[/tex]
last answer is correct
Step-by-step explanation:
[tex] - 3d + 5 = 14 \\ - 3d = 14 - 5 \\ - 3d = 9 \\ \frac{ - 3d}{ - 3} = \frac{9}{ - 3} \\ d = - 3[/tex]
hope this helps
