Answer:
b = 2
Step-by-step explanation:
3b + 2(b - 3) = 4
--distributive property-- 2(b - 3) = 2b - 6
3b + 2b - 6 = 4
(add like terms)
5b - 6 = 4
(add 6 to both sides)
5b = 10
(divide both sides by 5 to get b alone)
b = 2
The sum of a number and 32 is two-thirds the number and 45. (Algebra)
Answer:
he sum of a number and 16 is equal to 45. 2. The product of 6 and m is 216. 3. The difference of 100 and x is 57. 4. The quotient of z and 10 is 32. X+16= 45.
Step-by-step explanation:
Answer:
-2
Step-by-step explanation:
45 divided by 3 is 15 and if you multiply that by 2 you get 30. 32 - 2 is 30

Use the drawing tool(s) to form the correct answer on the provided graph.
The graph of f(x) = x is shown on the coordinate plane. Function g is a transformation off as shown below.
g(x) =3/4 f(x)
Graph function g on the same coordinate plane.
The graph of the function g(x) = 3/4 f(x) on the same coordinate plane as f(x) = x is attached below.
What is a graph?A graph can be defined as a pictorial representation or a diagram that represents data or values.
To graph the function g(x) = 3/4 f(x) on the same coordinate plane as f(x) = x, we need to perform the transformation of stretching the graph of f(x) by a factor of 3/4.
Determine the scale factor for the transformation. In this case, the scale factor is 3/4.
Starting at the x-intercepts and y-intercepts (if there are any), plot the points on the coordinate plane using the scale factor to stretch or shrink the graph as needed.
For example, the point (0,0) on the graph of f(x) becomes the point (0,0) on the graph of g(x). The point (1,1) on the graph of f(x) becomes the point (1, 3/4) on the graph of g(x).
Connect the plotted points with a smooth curve to obtain the graph of g(x).

Use the statement for the next 2 question: "If it is hot, then it is summer." 1) write
the hypothesis.
Answer:
simply no
Step-by-step explanation:
Answer: Hypothesis is "It is hot"
The general form of a conditional is "If hypothesis, then conclusion"
You may see it as "If P, then Q". P and Q are placeholders
In this case, the conclusion is "It is summer".
Considering only functions that have a rate of change less than that represented in the graph, which function has the greatest rate of change?
A. y = 7/6x + 2/3
B. y = 7/5x + 7/5
C. y = 6/5x + 11/5
D. y = 5/4x + 15/4
=======================================================
Explanation:
Slope is the same as the rate of change for any linear function. We ignore the y intercepts.
The slopes of the four equations, A through D, are: 7/6, 7/5, 6/5, and 5/4
This is because each equation is in y = mx+b form with m as the slope.
Convert each fractional slope into decimal form
7/6 = 1.167 approximately7/5 = 1.4006/5 = 1.2005/4 = 1.250We see that 7/5 produces the largest decimal, so 7/5 is the largest fraction of the four slopes.
Therefore equation y = (7/5)x+7/5 has the greatest rate of change.

when dividing, exponents subtract
Answer:
The Answer is 20^13
Step-by-step explanation:
to solve this equation all you have to do really is look at the exponents
anytime your dividing an exponent its subtraction so if the top is 20^k and ur looking for k look at the other numbers we have on the bottom of the fraction
20^4 and we have the answer as 20^9 , all we have to do it add the exponents 4 and 9 to get 13

Marley used 7 cups of water to make 4 loaves of French bread.
What equation can be used to model the total cups of water needed y for making x loaves of French bread? Write the equation in the form y =kx .
Answer:
Step-by-step explanation:
y=kx
7/4=1.75
6/4=1.5
The equation in the form y =kx will be as y = 7/4 x .
What are Proportional?Proportional the type of relationships between two variables where their ratios are equivalent.
In a proportional relationship, one variable is always a constant value by the other. That constant is known as the constant of proportionality.
A proportional relationship between the variables x and y is written as:;
y=k.x
For the given problem, y represents the cups of water needed for making x loaves of French bread.
We know that Marley used y=7 cups of water to make x=4 loaves of French bread. Substituting into the equation;
7=k.4
Solving for k:
k = 7/4
The equation to model the problem;
y = 7/4 x

What is the slope of a line parallel to the given line?
Question Blank
type your answer...
What is the slope of a line perpendicular to the given line?
Question Blank
type your answer...
Answer:
Step-by-step explanation:
I'm still not exactly sure what the question really is, but the level suggests that it is
y = (6/7)x + 5
Any line that is parallel to this line has a slope of 6/7
Any line that is perpendicular to this line is a little more complicated.
slope of given line * slope of perpendicular line = - 1
6/7 * perpendicular slope = - 1
Multiply by 7
6*perpendicular slope = - 7
Divide by 6
perpendicular slope = - 7/6
Kimberly tracked the cartoons shown on the channel her kids watch for a week. The probability that the show had animals in it was 0.7 . The probability that the show aired more than 10 times was 0.4. The probability that the show had animals in it and aired more than 10 times was 0.2. Which equation shows the correct use of the addition rule to determine the probability that a randomly selected show had animals in it or aired more than 10 times?
Answer:
p(A or more than 10) = 0.7 + 0.4 - 0.2 = 0.9
Step-by-step explanation:
Given the following probabilifu distribution :
Probability that show had animals in it :p(A) = 0.7
Probability that show aired more than 10 times : p(more than 10) = 0.4
Probability that show had animals and aired more than 10 times: p(A n more than 10) = 0.2
Recall:
P(A or B) = p(A) + p(B) - p(A n B)
Hence,
p(A or more than 10) = p(A) + p(more than 10) - p(A n more than 10)
p(A or more than 10) = 0.7 + 0.4 - 0.2 = 0.9
Why the following triangles are congruent!
Answer:
Because the sides BO and MA are marked with one line through the middle, which means those sides are congruent, angle A and Angle O are marked with one line, the angles are congruent, and angles W and N are marked with two lines, which means they are congruent. Therefore the triangles are congruent

solve 15-2x=3x
the solution is x=
Answer:
x=3
Step-by-step explanation:
15-2x=3x
solve for x:
15=5x
divided by 5:
3=x
Answer:
x = 3
Step-by-step explanation:
15 -2x = 3x {Add 2x to both sides}
15 = 3x + 2x
15 = 5x
15/5 = x {divide both sides by 5}
x = 3
When Joe started his job at the laundromat five years ago, his wage was $6.00 an hour. Today, his wage is $8.50 an hour. If Joe started his job in the base year, and his real wage is the same as when he started, what is the Consumer Price Index (CPI) today
Answer:
142
Step-by-step explanation:
The computation of the Consumer Price Index (CPI) today is shown below:-
Real Salary today / Real Salary 5 years ago = CPI today ÷ CPI 5 years ago
CPI today ÷ 100 = 8.50 ÷ 6
= 142
Therefore for computing the Consumer Price Index (CPI) today we simply applied the above formula and the same is to be considered
