Answer:
Vertex is (-5, -1)
(-3, 3) is a point on the parabola.
Step-by-step explanation:
f(x) = x² + 10x + 24
Let (h, k) be the vertex
h = -b/2a = -10/2(1) = -5
k = f(-5) = (-5)^2 + 10(-5) + 24
= 25 - 50 + 24 = -1
Vertex is (-5, -1)
Now, let x be some value different than -5, say -3
f(-3) = (-3)^2 + 10(-3) + 24
= 9 - 30 + 24 = 3
So, (-3, 3) is a point on the parabola.
Two linear functions are described below.

It takes 1/4 of an hour to mow 1/5 of his yard. How much of the yard can he mow per hour
Answer:
4/5
Step-by-step explanation:
if it take 1/4 of an hour to mow 1/5 of his yard.
First you have to find out what is 1/4 of an hour which in order to find you have to multiply 1/4 by 60 because it has 60 mins in an hour. You now have 15 mins and we already know there are 60 mins so we divide 60 by 15 which give you 4 then you multiply 1/5 by 4 which gives you 4/5 or 0.8.

The Ace Bicycle Shop charges a flat fee
of $4, plus $1 per hour, for the hire of a
bicycle. The Best Bicycle Shop charges
a flat fee of $8, plus 50 cents per hour.
Connie and her friends hire three bicycles
from Ace, and David and his brother hire
two bicycles from Best. After how many
hours will their hire costs be the same?
Answer:
x = number of hours = 8 hours
Step-by-step explanation:
Let
x = number of hours
There are 3 people who rented bicycle from each shop
Ace bicycle shop:
Total cost = 3(4 + x)
= 12 + 3x
Best bicycle shop:
Total cost = 3(8 + 0.50x)
= 24 + 1.5x
Equate both equations and solve
12 + 3x = 24 + 1.5x
12 - 24 = 1.5x - 3x
-12 = -1.5x
x = -12/-1.5
x = 8 hours
x = number of hours = 8 hours

What is the radius?
Find the length of the radius of the circle with an equation of
(x + 3)2 + (y-7)2 = 289.
Answer:
Radius = 17.
Step-by-step explanation:
If(h,k) is centre and rradius, the eqn. of circle is :(−x h)2+(y−k)2=r2
Comparing with the given eqn. of circle, we find, r2=289 Hence, radius is 17

Old Grandpa Joe left half his money to his granddaughter and half that amount to his grandson.
He left a sixth to his brother, and the remainder, £1,000, to the Dogs’ home.
How much did he leave altogether?
Answer:
£12000
Step-by-step explanation:
Granddaughter -- 1/2 of x
Grandson -- 1/2(1/2 of x)
Brother -- 1/6 of x
Dogs' home -- £1000
Therefore,
[tex]\frac{x}{2} + \frac{x}{4} + \frac{x}{6} + 1000 = x[/tex]
x = 12000

In a class of 30 students, 17 have a brother and 14 have a sister. There are 8 students who have a brother and a sister. What is the probability that a student chosen randomly from the class does not have a brother?
Answer:
[tex]\frac{14}{30} = 7/15[/tex]
The probability that a randomly selected student has a brother given they have a sister is 11/30.
We have given that,
Of 30 students in a class, 17 have a brother, 20 have a sister, and 11 have a brother and a sister.
What is the formula for probability?The Probability of an event is the ratio of the number of favorable events divided by the total number of outcome in the sample space.
Since there are 30 students in total, and 11 of them have both a brother and a sister,
Then 11/30 (11 out of the 30 students) would be the probability of a student having a brother given that they have a sister.

What is the sales tax of a $15.95 video game if the tax rate is 7%
Answer:
$17.07
Step-by-step explanation:
Step 1: Find the percent of the price
Convert 7% to fraction
[tex]= \frac{7}{100}\\\\=\frac{7}{100}\times \:15.95[/tex]
Multiply
[tex]=\frac{7\times \:15.95}{100}[/tex]
Multiply the factors
[tex]7\times \:15.95=111.65\\\\=\frac{111.65}{100}[/tex]
Divide
[tex]\frac{111.65}{100}=1.1165\\\\=1.1165[/tex]
Step 2: Add the percent off to the original price
[tex]15.95 + 1.1165\\\\= 17.0665[/tex]
Therefore, the total cost including tax in the nearest cent is 17.07 dollars

In ,bag A 12 oranges cost 2400
The price of one orange in bag A is
= 2400/12
= $200
In bag B 20 oranges cost $3000
The cost of one orange in bag B is
= 3000/20
= $150

Answer:
"The expression represents a cubic polynomial with 3 terms. The constant term is -10, the leading degree is 3, and the leading coefficient is (-1/6)"
Step-by-step explanation:
We have the expression:
[tex]-\frac{x^3}{6} - 10 + x[/tex]
First, what does that expression represents?
As al the powers of x are positive numbers, we can see that this is a polynomial, and the largest power is 3, so this is a polynomial of degree 3, also called a cubic polynomial.
How many terms are there?
The terms are the things separated by + or - symbols, is easy to see that there are 3 terms.
What is the constant term?
The constant term is the term where the variable, x, does not appear, here the constant term is: -10
What is the leading coefficient?
The leading coefficient is the coefficient that multiplies the term with the largest power of x, in this case, we can rewrite:
[tex]-\frac{x^3}{6} -10 + x = (\frac{-1}{6})*x^3 - 10 + x[/tex]
the leading coefficient is:
(-1/6)
There is a part of the statement that I can't read, i suppose that there says:
"leading degree"
this is just the largest power of x that appears in the polynomial, in this case, is 3.
Then the complete statement is:
"The expression represents a cubic polynomial with 3 terms. The constant term is -10, the leading degree is 3, and the leading coefficient is (-1/6)"

Equation: y = 5x - 2
Step-by-step explanation:
Slope = Change in y / Change in x
Change in y = +5
Change in x = +1
Slope = 5/1 or 5
Y-intercept = y-value where x = 0
x = 0, y = 3-5
y = -2
y-intercept = -2
Finally;
Equation: y = 5x - 2
Hope this helps!
Answer:
y = 5x - 2
Step-by-step explanation:
(1,3) (2,8)
y2 - y1 / x2 - x1
8 - 3 / 2 - 1

y = 5x + b
3 = 5(1) + b
