Answer:

b = (4/6) - a/2

Step-by-step explanation:

6b + 3a = 4

6b = 4 - 3a

b. = (4 - 3a)/6

b. = (4/6) - a/2

The value of b is (4 - 3a)/6, or the equation in terms of a is (4 - 3a)/6 after making the subject as b.

It is defined as the combination of constants and variables with mathematical operators.

In the provided expression, variable and constant are there

It is given that:

The equation in a and b, where a and b are the variables:

3a + 6b = 4

Here the indicated variable is b.

To find the value of b in terms of a make the subject as b:

Subtract 3a on both the sides in the equation 3a + 6b = 4:

The equation becomes:

3a + 6b -3a = 4 - 3a

6b = 4 - 3a

Divide by 6 on both sides:

The equation becomes:

6b/6 = (4 - 3a)/6

b = (4 - 3a)/6

Thus, the value of b is (4 - 3a)/6, or the equation in terms of a is (4 - 3a)/6 after making the subject as b.

Answer:

he has to make 12 shots

Step-by-step explanation:

Josh will have to make a minimum of 12 shots to the basket to reach his goal on Tuesday. Basically, 12 shots are 80% of 15 shots he decides to take every Monday and Tuesday.

  [tex]\rm Josh's goal= \dfrac{80}{100} x 15[/tex]

 [tex]\rm Josh's\ goal = 12[/tex]

Hence, Josh will have to make 12 free throws into the basket on Tuesday to be able to score at least 80% of his free throws as baskets.

Y=3/3

Y= 1

Answer:

a) x = 60

b) b = 110

Step-by-step explanation:

A)

2x and 120 are vertical angles.

vertical angles are equivalent.

2x = 120

divide both sides of the equation by 2

2x/2 = 120/2

x = 120/2

x = 60

B)

b + 20 and 130 are on the same side of the line

(I forgot what the math term is, but they're also equal)

b + 20 = 130

subtract 20 from both sides of the equation

b + 20 - 20 = 130 - 20

b = 130 - 20

b = 110

Answer:

y = -5x + 4

Step-by-step explanation:

In the equation y = mx + b , m stands for slope and b stands for the y intercept. In the coordinates (-1,4) the y value is 4 meaning that it's your y-intercept. The slope is already given to you so just add the X.

Answer:

y = -5x - 1

Step-by-step explanation:

Since you have the slope and a given point you can use the point-slope formula to solve for the y-intercept formula.

Point slope formula = y - y = m(x - x)

m = -5    (-1, 4)

y - 4 = -5(x +1)

y - 4 = -5x - 5

y = -5x - 1

Answer:

C the slope of a line is positive

Step-by-step explanation:

   Hypothesis: The phrase following the "if" part of a conditional statement. So the answer would be c- The slope of a line is positive.

C) the slope of a line is positive

A conditional statement has two parts: hypothesis (if) and conclusion (then).

We have the given statement as:

If the slope of a line is positive, then the line is not horizontal.

Here, "if" part of a conditional statement is the slope of a line is positive

So, the hypothesis of the statement is the slope of a line is positive

Therefore the correct option is (C).

Step-by-step explanation:

Sue's initial wage per hour = $10

Sue's wage per hour after the increase = $100

a. Economic surplus to be enjoyed = $100 - $10

                                                      = $90

Sue would enjoy an economic surplus of $90.

b. No, because in this case the wage per hour for each 400 student would be;

                                          =  [tex]\frac{100}{400}[/tex]

                                          = $0.25

                                          = 25 cents

Redistribution of income is the act of equal sharing of wealth among a certain number of people.

The problem here is that Sue would feel cheated with the division of the earnings among 400 students, but very happy when her wages was increased.

Though the income incentive redistribution programs reduce poverty, but it may be unfair.

Answer:

  5

Step-by-step explanation:

Put -2 where x is and do the arithmetic.

  f(x) = 2x² -3

  f(-2) = 2(-2)² -3 = 2(-2)(-2) -3 = 8 -3

  f(-2) = 5

Answer:

f(-2) = 5

Step-by-step explanation:

We just need to substitute x with -2 and simplify.

f(x) = 2x² - 3

f(-2) = 2(-2)² - 3

f(-2) = 2(4) - 3

f(-2) = 8 - 3

f(-2) = 5
