Answer:
slope= -3,y - intercept y = -2
Step-by-step explanation:
- Make y the subject by taking four on the opposite side of the equal sign.
2y = -6x - 4
- Divide throughout by 2 and from there you get the gradient which is also the slope.
- To get the y - intercept,the value of x =0. Thus you get y =-2.
Solve for y, z, x or t: x/m-x=n if m≠1
Select the example of an inequality.
o 14y = 2
0 32 - 4
044 = 15
4y < 64
Addison worked 11 more hours this week than last week. In total, she worked 65 hours this week and last week. Using the equation 2h + 11 = 65, how many hours (h) did Addison work last week?
Answer:
27

A pair of basketball shoes's normal price is $120. Jordan bought it at a discount of 10%. He had to pay 8% tax on the discounted price. If jordan put 15% of the final cost (including tax) as a down payment, how much money did he have to pay for the down payment?
Answer:
$17.50
Step-by-step explanation:
If the shoes are discounted at 10%, the price would be 90% of the original price
Discounted price = 0.9 x 120 = 108
Tax increases the price of the good. so, the discounted price would increase by 8%
1.08 x 108 =116.64
If Jordan pays 15% as a down payment, he would pay :
0.15 x 116.64 = 17.496

Step-by-step explanation:
While on a business trip to Brookfield, Haley treated her co-workers to a meal that cost $50. Haley knew that when the bill came, she would need to pay Brookfield sales tax of 14% and would want to leave an 18% tip on the original $50. Including tax and tip, how much did Haley's meal cost?
Answer:
$66
Step-by-step explanation:
The meal cost $50 without taxes.
The cost of tax:
$50*%14= $7
so she will pay a $7 tax
Also, she wants to tip %18 of the original $50 so:
$50*%18= $9
so she will tip $9
$50 + $7 + $9 = $66

Mike wants to make meatloaf. His recipe
uses a total of 4 pounds of meat.
If he uses a 3 to 1 ratio of beef to pork, how much pork will he use?
Answer:
[tex]1\:\mathrm{pound}[/tex]
Step-by-step explanation:
We can write the following equation using the information given:
[tex]3x+1x=4[/tex], where [tex]x[/tex] is some constant.
Solving, we get:
[tex]4x=4,\\x=1[/tex].
Therefore, we plug in [tex]x=1[/tex] to find the amount of meat he uses for each type:
Beef: [tex]3x=3(1)=3\:\mathrm{pounds}[/tex]
Pork: [tex]1x=1(1)=\fbox{$1\:\mathrm{pound}$}[/tex].
2/7 (14 h + 7/2) - 3h = 9

An information technology company produces 45% of its computer chips at a plant in St. Louis and the remainder of its chips at a plant in Chicago. It is known that 0.85% of the chips produced in St. Louis are defective, while 1.05% of the chips produced at the plan in Chicago are defective. What is the probability that a randomly chosen computer chip produced by this company is defective and was produced in St. Louis?
Answer:
the probability of the computer chip produced and defective is 0.003825
Step-by-step explanation:
The computation of the probability of the computer chip produced and defective is shown below
= Produced percentage × defective percentage
= 45% × 0.85%
= 0.003825
Hence, the probability of the computer chip produced and defective is 0.003825

Lily is selling ice cream cones and ice cream sandwiches. She sells 3 ice cream cones and 4 ice cream sandwiches for $14.25. She sells 5 ice cream cones and 2 ice cream sandwiches for $13.25. How much is an ice cream cone? How much is an ice cream sandwich?
Answer:
cost of ice cream cones = $1.75
cost of ice cream sandwiches = $2.25
Step-by-step explanation:
Let
x = cost of ice cream cones
y = cost of ice cream sandwiches
3x + 4y = 14.25 (1)
5x + 2y = 13.25 (2)
Multiply (2) by 2
10x + 4y = 26.50 (3)
3x + 4y = 14.25 (1)
Subtract (1) from (3)
10x - 3x = 26.50 - 14.25
7x = 12.25
x = 12.25/7
x = $1.75
Substitute x = 1.75 into (1)
3x + 4y = 14.25
3(1.75) + 4y = 14.25
5.25 + 4y = 14.25
4y = 14.25 - 5.25
4y = 9
y = 9/4
y = $2.25
Answer:
cost of ice cream cones = $1.75
cost of ice cream sandwiches = $2.25
Step-by-step explanation:
Let
x = cost of ice cream cones
y = cost of ice cream sandwiches
3x + 4y = 14.25 (1)
5x + 2y = 13.25 (2)
Multiply (2) by 2
10x + 4y = 26.50 (3)
3x + 4y = 14.25 (1)
Subtract (1) from (3)
10x - 3x = 26.50 - 14.25
7x = 12.25
x = 12.25/7
x = $1.75
Substitute x = 1.75 into (1)
3x + 4y = 14.25
3(1.75) + 4y = 14.25
5.25 + 4y = 14.25
4y = 14.25 - 5.25
4y = 9
y = 9/4
y = $2.25

Answer:
Row III and Row V
Step-by-step explanation:
Whole numbers are all positive numbers including 0. However, these numbers cannot have fractions or decimals. Integers include numbers that are negative and positive, however they cannot have fractions or decimals either. 0 counts as an integer, too. Rational numbers are numbers that can be written as a fraction. Decimals can be rational, too - they just have to either terminate (end at some point) or repeat. Knowing these rules...
-98 would qualify as an integer and a rational number - but not a whole number because it's negative. Row I is correct. 0 would qualify as an integer, whole number, and rational number. Row I is correct. -0.7878... would not qualify as an integer or whole number - it is a decimal - but it would qualify as a rational number since it repeats. Therefore, Row III is wrong. [tex]2\frac{15}{17}[/tex] would not qualify as an integer or whole number - it is a fraction - but it would qualify as a rational number. It can be written as a fraction. Row IV is correct. 10.5 would not qualify as an integer or whole number - it is a decimal number - but it could be rational since it can be written as [tex]10 \frac{1}{2}[/tex]. Row V is wrong.What is the value of the expression 3x2 – 2y, if x - -2 and y = -4. 0 20 52 O-8 02

The given expression at {x} = - 2 and {y} = -4 evaluates to 20.
What is function?A function is a relation between a dependent and independent variable. We can write the examples of functions as -
y = f(x) = ax + b
y = f(x, y, z) = ax + by + cz
Given is the expression -
3x² - 2y
The given equation is -
3x² - 2y
For {x} = - 2 and {y} = -4, we can evaluate the expression as -
3(-2)² - 2(-4)
3 x - 2 x - 2 - 2 x - 4
3 x 4 + 8
20
Therefore, the given expression at {x} = - 2 and {y} = -4 evaluates to 20.

Use substitution to solve the system.
3x+5y = 2
y = 2x-10
Answer:
x = 4, y = -2
Step-by-step explanation:
Answer:
x = 4
y = -2
Step-by-step explanation:
[tex]3x + 5y = 2[/tex]
[tex]y = 2x - 10[/tex]
[tex]3x + 5(2x - 10) = 2[/tex]
[tex]3x + 10x - 50 = 2[/tex]
[tex]13x = 52[/tex]
[tex]x = 4[/tex]
Now,
[tex]y = 2(4) - 10 [/tex]
[tex]y = 8 - 10[/tex]
[tex]y = - 2[/tex]

You call a taxi company to find out their rates. The taxi company charges $1.50 for the first mile, and $.90 for each additional mile. How far could you go for $20 if you give the driver a $2 tip? Write your answer, then write a written explanation of how you got your answer. Explain your steps in complete sentences!
Step-by-step explanation:
(2$+1.5&)+0.9$X=20$
3.5$+0.9$X=20$
0.9$x=20$-3.5$
x=16.5$/.9$
x=18.333
so he can travel 18.333miles.
first we need to add the two separated cause of 1.5 Dollar in $2 tip which give us 3.5 dollar that is to be subtracted from the $20 you have. then the money that is left in your pocket is 16.5 dollar s this will be deducted 0.9 for every mile so dividing 16.5 by 0.9 gives 18.333.

We use PEMDAS to determine the order in which the mathematical operations would be carried out.
PEMDAS is an acronym for Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction.
Multiplication comes first so;
6 × 9 + 4 × 3
54 + 12
We can then add both numbers.
54 + 12 = 66
