24 more than Holly's age is 67
Answer:
This question isn't really complete, but if you're asking what Holly's age is, then that's just 67 - 24, which is 43.
So Holly is 43, if that's the question.
Hi there!
»»————- ★ ————-««
I believe your answer is:
[tex]h + 24 =67[/tex]
[tex]h = 43[/tex]
»»————- ★ ————-««
Here’s why:
⸻⸻⸻⸻
We are given that 24 more than Holly's age is 67.⸻⸻⸻⸻
[tex]\boxed{\text{Setting up an equation:}}\\\\\text{'24 more than Holly's age'} \rightarrow h + 24\\\\\text{'is 67'} \rightarrow = 67\\\\\boxed{h + 24 = 67}[/tex]
⸻⸻⸻⸻
[tex]\boxed{\text{Solving for 'h'...}}\\\\h + 24 = 67\\-------------\\\rightarrow h + 24 - 24 = 67 - 24\\\\\rightarrow \boxed{h=43}\\\\\\\text{Holly should be 43 years old.}[/tex]

Find the value of t for a t-distribution with 12 degrees of freedom such that the area to the left of t equals 0.025. Round your answer to three decimal places, if necessary.
Answer:
-2.179
Step-by-step explanation:
Given :
Degree of freedom, df = 12
Area to the left = 0.025
The value of T can be obtained using either a t distribution table or a T value calculator :
t0.025, 12 (to the left) = t(1-0.025), 12 = t0.975,12 = - 2.1788
Therefor le, t value with 12 degree of freedom, with area to the left being 0.025 is - 2.179
Which is the equation of a line parallel to the line with the equation: y = −14x + 7
y = -4x - 7
y = 4x + 2
y = 14x − 12
y = −14x + 3
Answer:
y = −14x + 3
Step-by-step explanation:
Parallel lines have the same slope
The equation y = −14x + 7 is put in slope intercept form ( y = mx + b )
Where m = slope
-14 takes "m's" place meaning that the slope = -14
If parallel lines have the same slope than the equation of a line parallel to y = −14x + 7 must have a slope of -14
The only equation that has a slope of -14 is D

Work out the area of a rectangle with base, b = 38mm and perimeter, P =
100mm.
b
Let the height of the rectangle = h
2b + 2h = 100
2(38) + 2h = 100
2h = 100 - 76
h = 12mm
area of rectangle = base x height

The pair of equations y = 0 and y = -7 has how many solutions?
Answer:
2 solutions so it can be inferred that it might be a quadratic
Step-by-step explanation:
Answer:
no solutions
Step-by-step explanation:
y = 0 and y = - 7 are horizontal parallel lines.
Since they are parallel, they never intersect and so have no solutions.
In a paragraph, explain what the domain and range is for the function, and how you found your answer: f(x) = x2 + 6x - 25.
Answer:
Domain(-infinity,+infinity)
Range=f(x) >or= - 34
Step-by-step explanation:
Domain for every parabola the domain is (-infinity, +infinity) unless there are any restrictions
Range we look at the y value of the maximum point or minimum points
We find it by finding the turning point
F'(x) =2x+6
0=2x+6
-6=2x
x=-3
F(-3)=(-3)^2+6(-3)-23
=-34
So all value that exist on the f(x) must be greater or =-34

Find the vertex of f(x) = 3(x-7)(x+5)
Please show your work.
^^ I’ve been having a bit of trouble with this question :( although it’s simple quadratics is not my strong suit
Answer:
The vertex is at (1, -108).
Step-by-step explanation:
We have the function:
[tex]f(x)=3(x-7)(x+5)[/tex]
And we want to find its vertex point.
Note that this is in factored form. Hence, our roots/zeros are x = 7 and x = -5.
Since a parabola is symmetric along its vertex, the x-coordinate of the vertex is halfway between the two zeros. Hence:
[tex]\displaystyle x=\frac{7+(-5)}{2}=\frac{2}{2}=1[/tex]
To find the y-coordinate, substitute this back into the function. Hence:
[tex]f(1)=3((1)-7)((1)+5)=3(-6)(6)=-108[/tex]
Therefore, our vertex is at (1, -108).
Answer:
vertex (1, -108)
Step-by-step explanation:
First find the zeros
f(x) = 3(x-7)(x+5)
0 = 3(x-7)(x+5)
Using the zero product property
x-7 = 0 x+5 = 0
x = 7 x = -5
The x coordinate of the vertex is the average of the zeros
(7+-5)/2 = 2/2 =1
To find the y coordinate, substitute the x coordinate into the equation
y = 3(1-7)(1+5) = 3(-6)(6) = -108

Answer:
52.95x + 39.95(12)
Step-by-step explanation:
Answer:
52.95 x + 39.95 (12)
Step-by-step explanation:
cost per movie = 52.95
a monthly subscription is 39.95 and there are 12 months in a year so it would be 39.95 x 12
the x would be dependent on the amount of movie rentals and therefore the cost of the rentals = 52.95 x

The diagram shows a right angled triangle 15cm 31 what is value of h round to 1 decimal place
explanation:
the hypotenuse is 15 cm with the opposite side being h cm.
The angle is 31°
Thus, using trigonometric ratio, we have;
h/15 = sin 31
h = 15 sin 31
h = 15 × 0.5150
h = 7.725
Approximating to 1 decimal place gives;
h = 7.7 cm
