In a linear equation value of x and y (x, y) = ( -2 , 6) when the graph of y=-3x and x=-2 intercept .
What in mathematics is a linear equation?
There are only one or two variables in a linear equation. No variable can be multiplied by a number larger than one or used as the denominator of a fraction in a linear equation. All of the points fall on the same line when you identify the values that together make a linear equation true and plot those values on a coordinate grid.y= - 3x
Put x = -2 put in the equation
y = -3 * -2
y = 6
So, value of x and y (x,y) = ( -2 , 6)

The following table shows the different savings account available at Capital Bank. Use the table to answer questions
Kate is depositing $5,000 into an account for her son’s education. Which account should she choose?
A. Teen Savings, because her son is a teen
B. College Savings, because she meets the minimum deposit and it earns more interest
C. Regular Savings, because it earns compound interest.
D. Platinum Savings, because it has the highest interest rate.
Based on the accounts and the benefits they offer, Kate should choose B. College Savings, because she meets the minimum deposit and it earns more interest
Which account is best for Kate?Kate should pick the college savings account for two reasons with the first being that the $5,000 she wants to deposit meets the minimum deposit amount of $1,000.
The second reason is that the account earns more interest than other account.
Even though it is simple interest, the 9% is still much higher than the compound interest of 1% that the regular account gives.
Kate should choose college savings.

One freezer costs $623.95 and uses 90 kilowatt hours (kwh) of electricity each month. A second freezer costs $500 and uses 100 kwh of electricity each month. The expected life of each freezer is 12 years. What is the minimum electric rate in cents per kwh for which the 12-year total cost (purchase price + electricity costs) will be less for the first freezer?
The minimum electric rate in cents per kwh for which the 12-year total cost will be less for the first freezer is 8.61 cents
How to calculate the rate?Let x = minimum electric rate (Cents/kWh)
Total months in 12 years is 12*12 = 144 m
1st freezer
Total cost over 12 years is
623.95 (cost) + (90 kWh/m)*(144 m)(x/100 $/kWh)
= 623.95 + 129.6x
2nd freezer
Total cost over 12 years is
500 + 100*144*(x/100)
= 500 + 144x
For the 1st freezer to cost less over 12 years,
623.95 + 129.6x < 500 + 144x
123.95 < 14.4x
8.61 < x
The minimum rate is 8.61 cents per kWh

A polynomial p(x) is given as 2x^2-3kx+5
One of the zeros of p(x) is -1
Find k.
Answer:
[tex]k = -\frac{7}{3}[/tex]
Step-by-step explanation:
Given :
p(x) = 2x² − 3kx + 5
Since, -1 is a zero for p then :
p(-1) = 0
Solving the equation p(-1) = 0 for k :
p(-1) = 0
⇔ 2(-1)² − 3k(-1) + 5 = 0
⇔ 2 + 3k + 5 = 0
⇔ 3k = -5 - 2
⇔ 3k = -7
⇔ k = -7/3
NOTE :
If -1 is a zero of p
[tex]\Longrightarrow k = -\frac{7}{3}[/tex]
[tex]\Longrightarrow p(x) = 2x^2 - 3(\frac{-7}{3}) x + 5\\\Longrightarrow p(x) = 2x^2+ 7x + 5[/tex]

rounded to the nearest tenth, what is the perimeter of rectangle abcd? a. 10.8 inches b. 13.7 inches c. 15.0 inches d. 18.7 inches
The perimeter of the rectangle ABCD is 13.7 inches.
What is the perimeter of the rectangle?The perimeter of a rectangle is defined as the addition of the lengths of the rectangle's four sides.
The perimeter of a rectangle = 2(L+W)
Where W is the width of the rectangle and L is the length of the rectangle
⇒ sin30° = AD/AC
⇒ AD = AC(sin30°) = 5(1/2)
⇒ AD = 2.5 inches
⇒ sin60° = CD/AC
⇒ CD = AC(sin30°) = 5(√3/2)
⇒ CD = 4.33 inches
The perimeter of rectangle ABCD = 2(AD) + 2(CD)
The perimeter of rectangle ABCD = 2(2.5) + 2(4.33) = 5 + 8.66
Rounded to the nearest tenth
The perimeter of rectangle ABCD = 13.66 ≈ 13.7 inches

Rounded to the nearest tenth, what is the perimeter of rectangle ABCD?
rectangle ABCD with diagonal AC, labeled as measuring 5 inches, angle BAC measuring 30 degrees, angle BCA measuring 60 degrees, angle DCA measuring 30 degrees, and angle DAC measuring 60 degrees.
A rectangle restaurant kitchen has a perimeter of 38 m in an area of 88 m² what are the dimensions of the kitchen
The dimensions of the kitchen are 11m × 8m.
In geometrical mathematics, a polygon with four sides is referred to as a quadrilateral, while a quadrilateral with two opposed, parallel, and equal sides is referred to as a rectangle.
A rectangle has four equal-sized angles. There are four angles in a rectangle.
A rectangle has 90° angles on all sides.
The rectangle's diagonal is the separation or length of a line segment that connects any two opposed vertices.
Let l and w represent the length and breadth of the rectangular kitchen, respectively.
we know that area of a rectangle = length × width
perimeter of a rectangle = 2(l ₊ b)
Given that the rectangular kitchen has an area of 88 m².
A = 88 m²
l × w = 88 m² ....eq(1)
The perimeter of the rectangle is 38 m.
Perimeter (P) = 38 m
2(l+w) = 38 m
l+w = 19 m
l = 19 - w .....eq(2)
substitute eq(2) in eq(1).
l × w = 88 m²
(19 - w)w = 88
19w - w² = 88
-w²+19w-88 = 0
w²-19w+88 = 0
By factorization method, we get:
w²-11w-8w+88 = 0
w(w-11)-8(w-11) = 0
(w-11)(w-8)
w = 11 or w = 8
If w = 11,
then l = 19-11 = 8m
and If w = 8m
then, l = 19-8 = 11m
so the dimensions are 11m×8m
Hence we get the dimensions of the kitchen are: 11m×8m

The probability of rolling an odd number and then rolling a 2 is 1/12.
Option C is true.
What is Probability?
Probability is measure of the likelihood of an event to occur.
Given that;
A six - sided dice is rolled twice.
The sides are labelled 1-6.
Now,
In a dice odd number are 1, 3, 5
Hence, The probability of rolling an odd number = 3/6
And, The probability of rolling a 2 = 1/6
So, The probability of rolling an odd number and then rolling a 2
= 3/6 x 1/6
= 1/12
Hence, The probability of rolling an odd number and then rolling a 2 is 1/12.
Option C is true.

Using translation concepts, we have that:
4. The type is f(x + k), with k = 3, and a horizontal shift.
5. The type is kf(x), with k = 5 and a vertical stretch.
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.
For graph 4, we have function g(x) is a shift left of 3 units of function f(x), hence:
The type is f(x + k), with k = 3, and a horizontal shift.
For graph 5, we have that for each value of x, g(x) = 5f(x), hence:
The type is kf(x), with k = 5 and a vertical stretch.
