Answer:
a. the sign is interchange
it should be = x^2 - 3x + 4 - x^3 - 7x + 2
Answer:
see explanation
Step-by-step explanation:
(a)
The student has distributed the second parenthesis by 1 instead of - 1
(b)
Given
(x² - 3x + 4) - (x³ + 7x - 2)
distribute the first parenthesis by 1 and the second by - 1, that is
= x² - 3x + 4 - x³ - 7x + 2 ← collect like terms
= - x³ + x² - 10x + 6

Write a function rule for the table.
A. c = 18d + 11
B. c = 18d + 18
C. c = 11d + 18
D. c = 18d
Answer:
A. c = 18d + 11
Step-by-step explanation:
From the given table, we have two points : (1,29) and (2,47).
Now let us use slope formula to find the slope :
slope =18
Now we use point slope form to get the final equation.
Using point (1,29) and slope 18,
So final equation becomes c=18d +11
The answer is the Third solution.
example:
C = (18 × 2) + 11
C = 36 + 11
C = 47

The price of 600 grams of candy and 1.5 kg of cookies is $4.62. What is the price of one kg of cookies if it is $1.4 cheaper than 1 kg of candy?
Answer: $1.80
Step-by-step explanation:
600 grams - .6 kg
.6x+1.5y=4.62
y=x-1.4
.6x+1.5(x-1.4)=4.62
.6x+1.5x-2.1=4.62
2.1x=6.72
x=3.2 ( 1 KG of candy)
y=3.2-1.4
1.8=y (1 KG of cookies)
I rectangular prism with a square base has a high of 7 inches the base of the prism can be completely covered with no overlap by 16 squares that each have a edge length of 1 inch what is the total surface area of the rectangular prism
Answer:
144 square inches
Step-by-step explanation:
Total surface area of the rectangular prism = Sum of all the area of its sides
Since it has a square base which can be covered by 16 squares of length 1 inch each, then;
length of its base = 4 inches
So that,
i. Area of its base = [tex]length^{2}[/tex]
= [tex]4^{2}[/tex]
area of its base = 16 square inches
ii. Area of one of the surfaces of its sides = length x width (or base x height)
= 4 x 7
= 28 square inches
Sum of the area of its vertical sides = 4 x 28
= 112 square inches
Thus,
Total surface area of the prism = 16 + 16 + 112
= 144 square inches

The ratio of two numbers is 4 to 7. The sum of the numbers is 253. Find the
two numbers.
Answer:
28 and 49 are the two numbers whose sum is 77.
Step-by-step explanation:
A clothing business finds there is a linear relationship between the number of shirts, n (in thousands) it can sell and the price, P, it can charge per shirt. In particular, historical data shows that 3 thousand shirts can be sold at a price of $69 each, and that 7 thousand shirts can be sold at a price of $61 each Find the equation of the form P(n)=mn+b that gives the price P they can charge for n thousand shirts.
Answer:
[tex]P(n)=-2n+75[/tex]
Step-by-step explanation:
Let n represent the number of shirts in thousands and P represent the charge per shirt. n is the independent variable and P is the dependent variable.
Since 3000 shirts sell for $69 each, this can be represented as (3, 69). Also 7000 shirts sell for $61 each, this can be represented as (7, 61).
The equation showing the relationship is gotten using:
[tex]P-P_1=\frac{P_2-P_1}{n_2-n_1}(n-n_1) \\\\P-69=\frac{61-69}{7-3} (n-3)\\\\P=-2(n-3)+69\\\\P=-2n+75\\\\P(n)=-2n+75[/tex]

What role does substitution play when determining whether or not a given value is a solution to an equation or an inequality?
Answer:
Help verify values
Step-by-step explanation:
I basically help prove that the value fits and verifies that equation or inequality. By substituting a value for the variable within the equation or inequality and then solving it as a regular expression it should correctly output the same value on the other side of the equation or make the inequality true. For example, using the following inequality...
3x + 2 > 4
We can substitute the variable x for 2 and solve the inequality, if the inequality is true then we know that the value 2 is a correct and verified value.
(3*2) + 2 > 4
6 + 2 > 4
8 > 4 ... True
the learner's sell 340 vetkoek for 15 weeks .They charge R12.00 for each vetkoek .Calculate the profit they will make if the cost for each vetkoek is R4.00 and the cost of all ingredients is R623.48 per week
Step-by-step explanation:
Price Paid for vetkoeksR4.00 × 340
= R1 360.00
Price paid for IngrediantsR623.48 × 15
= R9 352.20
Total amount paid for the VetkoeksR9 352.20 + R1 360
= R10 712.20
Amount they made from the vetkoeksR12.00 × 340
= R4 080
ProfitR4 080 - R10 712.20
= -R6 632.20
The learners are making a R6 632.20 Loss

Step-by-step explanation:
We can see that the base TA is 4, and the second base RS is 2. We can see that the height is 4. The area of a trapezoid is:
[tex]A=\frac{h(b_1+b_2)}{2}[/tex]
Using this, we can substitute, and get:
[tex]A=\frac{4\cdot(2+4)}{2} = \frac{24}{2} = 12[/tex]
