Answer: w = 2
Explanation: To find the slope of a line, we use the formula y = mx + b, where m is the slope and b is the y-intercept. Since there is a variable, w, we can use this formula: m = 7 + w.
We know that m, or the slope of the line, is 9. If we substitute the value of 9 into that equation... we should get 9 = 7 + w.
It's simple mathematics from here.
7 plus what is 9?? 2. That's your answer. If you need help with slope-intercept and rate of change WITHOUT variables (besides x and y, of course), feel free to let me know!!
Where did I get that 7?
Usually, we use the slope formula to find the slope of a line when we know two points on the line. But if we already know the slope of a line, we can use the slope formula to find a missing coordinate of a point on the line.
We will be using this formula: y - y₂ = m(x - x₁)
This equation is useful when we know:
one complete coordinate point (x₁, y₁)and the slope of the line (m)and we want to find the other point.
(x₁, y₁) is the known point. In our example, it's (-7,-7).
(x, y), sometimes written as (x₂,y₂), is (-6, w) and represents the missing coordinate.
EXAMPLE (SEE IMAGE):
slope (m) = 3
y − y1 = m(x − x1)
We know m, and also know that (x1, y1) = (3,2), and so we have:
y − 2 = 3(x − 3)
That is a perfectly good answer, but we can simplify it a little:
y − 2 = 3x − 9
y = 3x − 9 + 2
y = 3x − 7

Question #5: You decided to paint one of the walls in the dining room the color blue. The shape of the wall is shown below. One gallon of paint covers 50 square feet. The wall will need two coats of paint. How many gallons of paint will you need to buy?
Total area of the wall:
Gallons of paint needed:
Answers
Answer:
Step-by-step explanation:
Draw a horizontal line from the top corner of the left wall to the right wall. Now you have a rectangle on the bottom 8’x10’ (80 square feet) and a triangle on the top with a height of 5’ and a base of 8’. 1/2 base times height =20. You need to paint 100 sq feet so you need 2 gallons.
Martika surfs with her friends at Virginia Beach. Her friend, Mark caught 8 waves out of 20 possible waves to ride in the shore. They plan to stay out in the water for 50 more waves. How many of the 50 waves do you predict Mark will catch?
Answers
Answer:
40 waves
Step-by-step explanation:
Prob (Mark catches waves) = Times waves caught / Total waves = 8 / 20 = 4 / 5 = 20%
Predicted waves out of 50 , caught = 4 / 5 or 20% of 50 = (4 / 5) x 50 = 40
Alternatively, multiplying numerator & denominator of wave catch probability ie 4 / 5 with 10 each , we get (4 x 10) / (5 x 10) = 40 / 50 . This also signifies 40 out of 50 waves are predicted to be caught.Kevin needs to buy some cardboard to build a box 11 inches long, 7 inches wide, and 10 inches high.

Step-by-step explanation:
Sine equals opposite over hypotenuse, which would be y/19. To find y multiply by 19 to get y=19sin33°
The values given are 19 (hypotenuse), y (adjacent side), and the angle (33°)
The formula for cosine is adjacent side divided by the hypotenuse
After plugging in the values given into the formula cosx=ad/h, we have:
Cos33°=y/19 Here, we need to isolate the Y
And, the final result is
19Cos33°= Y
So, the correct answer is the letter D

Step-by-step explanation:
An obtuse triangle has one angle measuring more than 90º but less than 180º (an obtuse angle). It is not possible to draw a triangle with more than one obtuse angle. Note: It is possible for an obtuse triangle to also be scalene or isosceles. An equiangular triangle has three congruent angles.
