what does “b” equal?
Answers
-10 = -b/4
to get b multiply both sides by 4
-10 *4 = -40
since b already has the negative sign the 40 would be positive
so b = 40

Perform the indicated operations. x+1/3y+x-2/4y-x=3/6y
Answers
The student's question seems to be about algebraic operations with an unclear equation, but the provided example with y = 9 + 3x demonstrates how to create a table and graph of a linear equation with a slope of 3 and y-intercept of 9.
Explanation:The student's question involves performing the indicated operations with algebraic expressions that include variables and fractions. The expressions mentioned resemble an equation that could potentially be simplified or solved, but the question as written contains typos and lacks clear structure. Consequently, to provide an accurate answer, we would need the correct and complete version of the equation.
However, in similar problems, one would typically combine like terms, find a common denominator for fractions, and simplify the equation to solve for the variable. For the equation y = 9 + 3x, to create a table of values, one can choose different values of x, substitute them into the equation, and calculate the corresponding y values. Then, plotting these points on a graph would show the linear relationship represented by the equation with a slope (m) of 3 and a y-intercept (b) of 9.

The basket of golf balls at a miniature golf course contains 18 golf balls, of which 9 are red. What is the probability that a randomly selected golf ball will be red?
Answers
Final answer:
The probability that a randomly selected golf ball will be red from a basket of 18 balls, with 9 red, is 1/2 or 50%.
Explanation:
The question is asking about the probability of selecting a red golf ball from a basket that contains 18 golf balls, with 9 of them being red. To find this probability, we divide the number of red golf balls by the total number of golf balls.
Here is the calculation:
Number of red golf balls: 9
Total number of golf balls: 18
Probability (P) of selecting a red golf ball: P = Number of red golf balls / Total number of golf balls
P = 9 / 18
P = 1/2 or 0.5 or 50%
Therefore, the probability that a randomly selected golf ball will be red is 1/2, which can also be expressed as 0.5 or 50%.
Line g has a slope of -4/7. Which of the following equations represents a line that is perpendicular to line g?
A) Y= -7/4x
B) Y= -4/7x
C) Y= 4/7x
D) Y= 7/4x
Answers
The equation that represents a line perpendicular to line g is Y= 7/4x (option D).
Explanation:A line that is perpendicular to line g will have a slope that is the negative reciprocal of -4/7. The negative reciprocal of a slope is found by flipping the fraction and changing the sign. The negative reciprocal of -4/7 is 7/4. Therefore, the equation that represents a line perpendicular to line g is Y= 7/4x (option D).

Answers
205,000 - 1,100w - 12% = e
w = weeks he worked
e = earnings
If he works 4 weeks, then we fill in w with 4:
205,000 -1,100(4) - 12% = e
1,100 x 4 = 4,400
Now subtract:
205,000 - 4,400 = 200,600
Now to get his commission, turn the percent into a decimal:
12% ----> .12
Then multiply that by the sales after draws:
200,600 x .12 = 24072
That means that Jim Smith got $24072 from commission.

2x2=4x2=8x2=16x2=32x2=64
To rewrite 64 using 2 as the base, the exponent is 6.
Explanation:To rewrite 64 using 2 as the base, we need to find the exponent that represents the power of 2 that equals 64. In other words, we need to solve the equation 2 to the power of x equals 64. We can do this by finding the logarithm with base 2 of 64. Using a calculator, we find that log base 2 of 64 is 6. Therefore, the exponent is 6.

(c) Determine the difference of outputs of any two inputs that are 3 units apart. Show your work.
(d) What do you notice about the ratios of the differences in the outputs to the input intervals? Explain your answer.
Answers
Consider from x = -5 to x = -4, they are 1 unit apart and the difference of their outputs is given by:
-3 - (-11) = -3 + 11 = 8.
Thus, the value of the output increases by 8 units for each one unit increase in the input.
Part B:
Consider from x = -3 to x = -1, they are 2 units apart and the difference of their outputs is given by:
21 - 5 = 16.
Thus, the value of the output increases by 16 units for each two units increase in the input.
Part C:
Consider from x = 0 to x = 3, they are 3 units apart and the difference of their outputs is given by:
53 - 29 = 24.
Thus, the value of the output increases by 24 units for each three units increase in the input.
Part D:
It can be noticed that the ratio difference in the outputs to the input intervals are equal for all the given input intervals.
i.e 8 / 1 = 16 / 2 = 24 / 3.

What is the value of x in the equation 1/5x-2/3 y = 30, when y = 15?
A.4
B.8
C.80
D.200
Answers
The value of x in the given equation 1/5x-2/3 y = 30 when y = 15 is given by option D. x = 200.
To find the value of x in the equation 1/5x - 2/3y = 30 when y = 15,
substitute the value of y into the equation and then solve for x.
Equation is 1/5x - 2/3y = 30
Substitute y = 15:
1/5x - 2/3(15) = 30
Now, calculate the value of 2/3(15):
2/3 × 15 = 30/3 = 10
Now, the equation becomes:
1/5x - 10 = 30
To isolate the term with x, add 10 to both sides of the equation:
1/5x = 30 + 10
1/5x = 40
Finally, to find x, multiply both sides by 5:
x = 40 × 5
x = 200
Therefore, the value of x in the equation when y = 15 is option D. x = 200.

What is 15 + 17- 100 + 1000 + (-132) x 0?
Answers
= 932 + (-132) * 0
= 932
You stated that the answer should be 0 which is utterly incorrect. Had the question been
=(15 + 17 - 100 + 1000 + (-132)) * 0
Then you'd be correct. But as the way the actual question is written the multiply by 0 is only applied to the (-132)
The result of the expression 15 + 17 - 100 + 1000 + (-132) x 0 is 932.
Multiplication first according to the order of operations (PEMDAS/BODMAS):
(-132) x 0 = 0
Now, substitute the result back into the equation:
15 + 17 - 100 + 1000 + 0
Next, perform the addition and subtraction from left to right:
15 + 17 = 32
32 - 100 = -68
-68 + 1000 = 932
So, the final answer is 932.
A line segment has endpoints at (–1, 4) and (4, 1). Which reflection will produce an image with endpoints at (–4, 1) and (–1, –4)?
a reflection of the line segment across the x-axis
a reflection of the line segment across the y-axis
a reflection of the line segment across the line y = x
a reflection of the line segment across the line y = –x
Answers
Answer:
a reflection of the line segment across the line y = –x
Step-by-step explanation:
Reflecting across the line y = -x switches the x- and y-coordinates and negates both. This will map
(-1, 4)→(4, -1)→(-4, 1) and
(4, 1)→(1, 4)→(-1, -4)
The reflection that produces an image with endpoints at (–4, 1) and (–1, –4) is a reflection of the line segment across the line y = -x.
Option D is the correct answer.
What is a reflection?There are two ways of translation.
Along x-axis:
(x, y) – (x, -y)
Along y-axis:
(x, y) - (-x, y)
We have,
The reflection of a point over the x-axis involves changing the sign of its
y-coordinate while leaving the x-coordinate unchanged.
The reflection of a point over the y-axis involves changing the sign of its
x-coordinate, while leaving the y-coordinate unchanged.
The reflection of a point over the line y = x involves swapping its x and y-coordinates.
The reflection of a point over the line y = -x involves swapping the sign of its x and y-coordinates.
To find the reflection that produces an image with endpoints at (–4, 1) and (–1, –4), we need to reflect the original line segment across a line that produces an image with the same length and orientation as the given endpoints.
One way to do this is to plot the points and draw the line segment, then draw the candidate lines of reflection and see which one produces the desired image.
Another way is to compute the midpoint of the original line segment and see which reflection takes that midpoint to the midpoint of the desired image.
Using the second method, the midpoint of the original line segment is:
= ((–1 + 4) / 2, (4 + 1) / 2)
= (1.5, 2.5)
The midpoint of the desired image is:
= ((–4 + –1) / 2, (1 + –4) / 2)
= (-2.5, -1.5)
To find the reflection that takes (1.5, 2.5) to (-2.5, -1.5), we can see that this is the reflection across the line y = -x.
Therefore,
The reflection that produces an image with endpoints at (–4, 1) and (–1, –4) is a reflection of the line segment across the line y = -x.
