I'm doing systems of equations and inequality, solving by graphing, and was wondering how to do this problem. Thank you!
Answers
Answer:
You need to graph the two lines. The solution is the point at which they intersect.
Step-by-step explanation:
To make things easier, first, you turn the first equation into slope-intercept form:
y = 2x + 5
Also, I didn't provide the answer because you just asked how to do it, but I can help with that if you need.

Malia has $10 to spend at the fall carnival. She decides to order an ice cream cone for herself and one for her sister.
a. If the cost of each ice cream cone is $2.35, how much will she spend on the ice cream cones? Write an equation and solve.
b. How much change will Malia receive? Write an equation and solve.
Answers
Answer:
Malia's allowance changed from $10.00 to $(10 - 2x) after buying ice cream cones.
Step-by-step explanation:
We are given the following information:
Malia's allowance to spend at carnival = $10.00
Ice cream ordered by her = 2
Let x dollars be the cost of one ice cream cone.
Total money spent on ice creams =
Formula:
change in Malia's allowance = total allowance - money spent on ice cream cones = 10 - 2x

Jorge says there are 198 inches in 5.5 yards. Is he correct. Explain your answer. Show your work.
Answers
Answer: yes, he is correct
Step-by-step explanation:
since there is 36 inches in 1 yard, we will multiply 5.5 by 36 to find out how many inches are in 5.5 yards. since 5.5 yardsx36 inches in one yard=198 inches, Jorge is correct.
Yes, he is correct, because if in one yard is 36 inches, and half a yard is 18 inches, if you multiply 36 by 5, you get 180. Then add the half yard of 18 to have 5.5 yards, or 198 inches. :)

4.5 L of orange juice is needed to add to 18 L of pineapple juice to make the fruit juice recipe with the ratio of 2 parts orange juice to 8 parts pineapple juice. The correct option is B.
What is an expression?An expression is a grouping of one or more mathematical or logical operators, operands (values, variables, or other expressions), and brackets in mathematics and computer programming that denote a computation that can be evaluated to generate a value.
The correct proportion that can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice is:
2/8 = j/18
This proportion is based on the ratio of 2 parts orange juice to 8 parts pineapple juice in the recipe. We can use this proportion to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice by cross-multiplying:
2/8 = j/18
2 × 18 = 8 × j
36 = 8j
j = 4.5
Therefore, 4.5 L of orange juice is needed to add to 18 L of pineapple juice to make the fruit juice recipe with the ratio of 2 parts orange juice to 8 parts pineapple juice.

Marcus has a 48-ounce soda. He drinks 15 ounces. What is the percentage of ounces Marcus has left from his soda? Round your answer to the nearest tenth.
A) 68.8
B) 45.6
C) 86.8
D) 34.9
Answers
Answer: A) 68.8%
Step-by-step explanation:
48-15=33
He has 33 oz of soda left. Divide 33/48 and then multiply by 100 to get a percentage. you get 68.75% but you have to round up the the nearest tenth so it will be 68.8%
48-15=33
therefore he has 33 ounces left. so to work out the percentage you do the amount left divided by the total x100
33/48 x100 = 68.75
Because the answer wants the result rounded it will round up the the nearest 10th the be 68.8 which is A

Fredrick and Kate have 17 1/3 cups of flour. They want to make loaves of banana bread for a bake sale. Fredrick has a recipe that calls for 1 5/8 cups of flour
Kate has a recipe that calls for 1 3/4 cups of flour. Select the statements that are true.
Answers
Answer:
Fredrick's recipe will make 10 whole loaves & There will be less flour left over if Fredricks recipe is used
Step-by-step explanation:
Fredrick's recipe
17 1/3 ÷ 1 5/8 = 10 2/3
Kate's recipe
17 1/3 ÷ 1 3/4 = 9 19/21
So Fredrick's recipe will make 10 whole loaves
9 19/21 is less than 10 2/3 so there will be less flour left over if Fredricks recipe is used
Find the slope from the graph.
-1/2
-4/3
3/4
-3/4
Answers
Answer: 3/4
Step-by-step explanation:
To find the slope from the graph, we need to look at the rise and run of the line. The slope is the ratio of the vertical change (rise) to the horizontal change (run).
Let's analyze the given options:
-1/2: This means that for every 2 units the line moves horizontally, it moves down 1 unit vertically.
-4/3: This means that for every 3 units the line moves horizontally, it moves down 4 units vertically.
3/4: This means that for every 4 units the line moves horizontally, it moves up 3 units vertically.
-3/4: This means that for every 4 units the line moves horizontally, it moves down 3 units vertically.
So, from the given options, the slope is 3/4. This indicates that for every 4 units the line moves horizontally, it moves up 3 units vertically.
Remember, the slope of a line is a measure of how steep the line is. It tells us how much the line is rising or falling as we move along the x-axis.
Use the slope formula to solve this question:
The slope formula is as followed:
y₂ - y₁
x₂ - x₁
where (x₁, y₁) and (x₂, y₂) are two sets of coordinates
Pick the two points on the line:
(0, 5) (4, 2)Now, plug them into the equation and solve:
y₂ - y₁
x₂ - x₁
[tex]\frac{2-5}{4-0}[/tex] = [tex]\frac{-3}{4}[/tex]
The slope of the line is -3/4

Yes, they should plan for the skate park because the sample had about 53.6% people vote yes.
Answers
Yes, they should plan for the skate park because the sample had about 46.4% people vote yes. Thus, option C is correct.
What is a sample?A sample is characterized as a more workable and compact version of a bigger group. a smaller population that possesses the traits of a bigger group. Since the population size exceeds the threshold big to accommodate all those who participated in the test, a subsection of the population is utilised in statistical analysis.
The details that are given:
the needed percentage to build a skateboard = 40 %
The total number of voters = 125
The people who responded yes = 58
The percentage of the people who voted will be:
= 58/125 * 100
= 46.4 %
As the value of 46.4 % > 40%, the individual should be able to vote.
Therefore, option C is correct.

One out of every 9 light bulbs is defective.
What constant of proportionality relates defective bulbs to total bulbs?
Answers
The constant of proportionality that relates defective bulbs to total bulbs is 1 / 9.
What is Constant Proportionality?The ratio connecting two given numbers in what is known as a proportional relationship is the constant of proportionality. Constant ratio, constant rate, unit rate, constant of variation, and even rate of change are other names for the constant of proportionality.
Given:
One out of every 9 light bulbs is defective.
Total bulbs = 9
So, Defective bulbs = 1
Thus, Constant of proportionality = Defective bulbs / Total bulbs.
Constant of proportionality = 1 / 9
Hence, the constant of proportionality that relates defective bulbs to total bulbs is 1 / 9.
