The zero of the linear function will be at (1, 0).
A linear function is the one which can be represented in the form y = ax + b where a, b are coefficients and x, and y are independent and dependent variables respectively. The zero of a line is the point where the line crossed the x-axis which is also known as the x intercept. The equation of the line in slope intercept form is given as y = mx + c where m is the slope and c is the y intercept. The slope of line from points (0, 5) and (2, -5) can be found by m = -5 - 5/2 -0
m = -10/2
m = -5
Now, putting this and the point (0, 5) in y = mx + c we get
5 = -5×0 + c
=> c = 5
Now, equation of line is y = -5x + 5 and for x intercept we put y = 0
0 = -5x + 5
5x = 5
=> x = 1
=> (1, 0) which is the required point

2. Zandile invests her Christmas bonus for R 875.00 in a bank that offers
interest rates of 9% p.a. compounded half-yearly. How much interest will she
have earned after 6 years? I want the interest
Answers
After 6 years, Zandile earns an interest of rupees 608.9 after investing her Christmas bonus for R 875.00 in a bank that offers interest rates of 9% p.a. compounded half-yearly.
What is interest?The simplest way to calculate interest is as a percentage of the principal. For instance, if you agreed to borrow $100 from a friend with 5% interest, the interest you would pay would only be 5% of $100: $100(0.05) = $5.
What is compound interest?Compound interest is when an amount receives interest on top of it each time interest is paid on the original amount. The principal (original) sum and the interest that has already accrued over the course of previous periods are used to calculate compound interest.
Here,
Principal amount= 875
Rate of interest= 9% pa
Compounding= half-yearly (2/year)
Time= 6 years
A = P(1 + r/n)ⁿᵇ
A=final amount
P=initial principal balance
r=interest rate
n=number of times interest applied per time period
b=number of time periods elapsed
A=875(1+9/6)⁶*²

The sum is the measure of three angles of a triangle is 180 degrees. In a triangle, the measures of an angle are x,x+12 and x-48. What is the measure of each angle?
Answers
Answer:
24° , 72° , 84°
Step-by-step explanation:
sum the 3 angles and equate to 180 , that is
x + x + 12 + x - 48 = 180
3x - 36 = 180 ( add 36 to both sides )
3x = 216 ( divide both sides by 3 )
x = 72
Then the measure of the 3 angles are
x = 72°
x + 12 = 72 + 12 = 84°
x - 48 = 72 - 48 = 24°

If a falling object travels a distance given by the formula d = 4t + [tex]6t^{2}[/tex] where d is the measured in feet and t is measured in seconds, then the time taken by the object to travel 68 feet is 3.0496 seconds

Where d is the distance traveled in feet
t is the time taken in seconds
Here
The distance traveled = 68 feet
Therefore the equation will be

Answers
The correct option is option B i.e., 36 + 9 = 3(12 + 3) is an equation representing distributive property.
What is distributive property ?
Distributive property states that the outcomes are the same whether the numbers in parenthesis are added before or after multiplication.
We know that according to the distributive property both sides must be equal such that the outcomes are same whether the numbers in parenthesis are added before or after multiplication. The expression for distributive property is given as : a(b + c) = ab + ac
So , checking the options one by one :
A) 36 + 9 = 45 ; is not an equation representing distributive property as it doesn't satisfy the criteria of a distributive property.
B) 36 + 9 = 3(12 + 3) is an equation representing distributive property as it satisfies the criteria mentioned above i.e.,
36 + 9 = 3 × 12 + 3 × 3
36 + 9 = 36 + 9
45 = 45
C) 36 x 9 = 9 x 36 is not an equation representing distributive property.
D) (12 + 3) × 3 = 3 × (12 + 3) is not an equation representing distributive property because both sides are written in the same way.
Therefore , correct option is option B i.e., 36 + 9 = 3(12 + 3) is an equation representing distributive property.

you and three friends share a sushi boat at House of Kobe the cost of the boat is $50 you each also pay for a soft drink that is $2.39 what is the total cost of the meal after you pay 6% tax
Answers
ANSWER
$63.13
EXPLANATION
We have that the cost of the boat is $50.
Each of you and your friends (that is four of you) will pay for a soft drink that cost $2.39 each.
The cost of the soft drinks will therefore be:
4 * 2.39 = $9.56
Adding the cost of the boat, total cost will be:
$9.56 + $50 = $59.56
Now, we have to add a tax of 6%, so we find 6% of total cost:
[tex]\frac{6}{100}\cdot\text{ 59.56 = \$3.57}[/tex]Finally, add the tax to the cost:
$59.56 + $3.57
= $63.13
You pay a total of $63.13 (including tax)

The simple interest formula is A = P(1+r t) then the value of t =33.2210 years.
What is meant by simple interest?Simple interest is a quick and simple formula for figuring out how much interest will be charged on a loan. The daily interest rate, the principle, and the number of days between payments are multiplied to calculate simple interest.
The simple interest formula is equal to
A = P(1+r t)
where, A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest
t is Number of Time Periods
P = $ 3300
A = $ 10700
r = 6.75 % = 6.75 / 100 = 0.0675
substitute in the formula above
$10700 = 3300(1+0.0675 t)
simplifying the above equation, we get
Divide both sides by 3300
[tex]$\frac{3300(1+0.0675 t)}{3300}=\frac{10700}{3300}$$[/tex]
Simplifying the above equation, we get
[tex]$1+0.0675 t=\frac{107}{33}$$[/tex]
Subtract 1 from both sides
[tex]$1+0.0675 t-1=\frac{107}{33}-1$$[/tex]
Simplifying the above equation, we get
[tex]$0.0675 t=\frac{74}{33}$$[/tex]
Divide both sides by 0.0675
[tex]$\frac{0.0675 t}{0.0675}=\frac{\frac{74}{33}}{0.0675}[/tex]

The equation of the line by using slope value is: y = x -9
What is slope of a line?
The slope of a line explain the steepness of the line segment. It is ration of the coordinates of the y-axis and the vertical coordinates of the x-axis. Depending upon the slope value, it is classified as whether lines are parallel or perpendicular.
According to the question, the given parameters for the line segment is as written below:
Equation of a line = x + 2 and the coordinate points = (6, -3): (x = 6; y = -3)
Now, by using standard equation for the line segment: y = mx + c
where, 'm' is the slope; c is the y-intercept; (x, y) are coordinates
Substituting given values that is slope and y-intercept in the standard equation, we get:
y = mx + c
⇒ -3 = (1)(6) + c
⇒ c = -3 - 6 = -9
Therefore, the value of the y-intercept is: c = (-9)
equation of the line by substituting the value of the y-intercept as well as slope value:
y = (1)x + (-9) = y = x -9

"The shape is a rhombus if and only if the diagonals are perpendicular and the sides are congruent” will be;
⇒ p ↔ (q ∧ r).
Thus, The correct representation of statement ''The shape is a rhombus if and only if the diagonals are perpendicular and the sides are congruent'' will be;
⇒ p ↔ (q ∧ r).
