Answer:
A
Step-by-step explanation:
The formula for the slope of the line is:
m = [tex]\frac{y_{1}-y_{2}}{x_{1}-x_{2}}[/tex]
Assuming that y1 is 17, y2 is -11, x1 is -9 and x2 is 5, we can plug it in the equation:
m={17-(-11)}/{-9-5}
m=28/-14
m=-2
Therefore, A

Answer:
y=1/2x-5
Step-by-step explanation:
We have slope so we just need to find the y intercept.
slope intercept formula is
y=mx+b
(m) is slope
(b) is y int
y=1/2x+b
now apply our given x and y values (4 & -3)
-3=1/2(4)+b
simplify
-3=2+b
subtract 2 from each side
-5=b
put that into our equation
y=1/2x-5
Graph the function y=12x+1.

URGENT give the measure of the complement of the angle 75.25 degree
Answer:
14.75°
Step-by-step explanation:
The sum of the measures of complementary angles is 90 deg.
Let the complement have measure x.
x + 75.25 = 90
x = 90 - 75.25
x = 14.75
Answer: 14.75°
Answer:
14.75
Step-by-step explanation:
complementary angles add up to 90
x + 75.25 = 90
90 - 75.25 = answer
14.75

The Malthouse Charity Run is a 5 kilometre race. The time taken for each runner to complete the race was recorded. The data was found to be normally distributed with a mean time
of 28 minutes and a standard deviation of 5 minutes.
A runner who completed the race is chosen at random.
Write down the probability that the runner completed the race in more than 28 minutes.
3b. [2 marks]
Calculate the probability that the runner completed the race in less than 26 minutes.
3c. [3 marks]
It is known that 20% of the runners took more than 28 minutes and less than minutes to complete the race.
Find the value of .
Answer:
0.5 ; 0.34458
Step-by-step explanation:
Given that:
Mean (m) = 28
Standard deviation, s = 5
To obtain the Zscore :
Z = (x - m) / s
1.) P(x > 28)
Z = (28 - 28) / 5
Z = 0
P(Z > 0) = 0.5 (Z probability calculator)
2.) P(x < 26)
Z = (26 - 28) / 5
Z = - 0.4
P(Z > -0.4) = 0.34458 (Z probability calculator)

6x+5y=19
2x+3y=5
Elimination Method to Solve Linear Equations
Answer:
x = 4 and y = -1
Step-by-step explanation:
Given that,
6x+5y=19 ... (1)
2x+3y=5 ...(2)
We need to solve the above equations.
Multiply equation (2) by 3.
6x+9y=15 ...(3)
Subtract equation (1) and (3).
6x+5y-(6x+9y)=19-15
6x+5y-6x-9y = 4
-4y = 4
y = -1
Put the value of y in equation (2).
2x+3(-1)=5
2x-3=5
2x=8
x=4
So, the solution of the above equations are x = 4 and y = -1.

After graduation, Duke's grandfather spent $158.81 taking the entire
family out to eat at a buffet. Adults ate for $8.99 and children ate for
$6.99. The number of adults was one more than twice the number of
children. Which system of equațions is used to find a, the number of
adults, and c, the number of children in Duke's family?
A. 8.99a + 6.99c=158.81
a=2c + 1
B. 6.99a + 8.99c =158.81
c=2a + 1
C. 8.99a + 6.99c = 318.62
c =2a + 1
D. 8.99a - 6.99c = 158.81
a =2c + 1
Answer:
A. 8.99a + 6.99c=158.81
a=2c + 1
Step-by-step explanation:
Let us represent
The number of Adults = a
The number of children = c
Duke's grandfather spent $158.81 taking the entire family out to eat at a buffet. Adults ate for $8.99 and children ate for $6.99.
$8.99 × a + $6.99 × c = $158.81
= 8.99a + 6.99c = 158.81
The number of adults was one more than twice the number of children.
a = 2c + 1
Hence:
The system of equations used are:
8.99a + 6.99c = 158.81
a = 2c + 1
Option A is correct

Rounded to the nearest hundredth, what is the positive solution to the quadratic equation 0=2x2+3x-8? Quadratic formula: x =StartFraction negative b plus or minus StartRoot b squared minus 4 a c EndRoot Over 2 a EndFraction
Answer:
1.39
Step-by-step explanation:
According to the problem, calculation of the given data are as follows,
Given equation = 0=2x2+3x-8
Here, we use general formula of quadratic equation, then
[tex]x = \frac{-b+-\sqrt{b^{2} - 4ac} }{2a}[/tex]
By taking the value by given equation,
a = 2, b = 3, c= -8
by putting the value in equation , we get
x = [- 3 ± √3^2 - 4(2 × -8)] ÷ 2×2
= [- 3 ± √73] ÷ 4
= [- 3 ± 8.544] ÷ 4
So, for positive solution, we get
x = (-3 + 8.544) ÷ 4
x = 1.386 or 1.39

Homer the Hungry Hippo is munching on the lily pads in his pond. When he got to the pond, there were 30 lily pads, but he is eating 5 lily pads an hour. Henrietta the Hungrier Hippo found a better pond with 38 lily pads! She eats 7 lily pads every hour.
If Homer and Henrietta start eating at the same time, when will their ponds have the same number of lily pads remaining?
How many lily pads will be left in each pond at that time?
Answer:
After 5 hours, they will each have 10 lily pads left..
Step-by-step explanation:
30|25|20|15|10|5|0
38|31|24|17|10|3
After 4 days same number of lily pads remained.
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
Homer got to the pond, there were 30 lily pads, but he is eating 5 lily pads an hour.
and, Hungrier Hippo found a better pond with 38 lily pads. She eats 7 lily pads every hour.
let after x days same number of lily pads remained.
So, 30 - 5x = 38 - 7x
30- 38 = -7x + 5x
-8 = -2x
x= 4
Hence, After 4 days same number of lily pads remained.
