Answer:
(a,b) = (49/9 , 91/18)
Step-by-step explanation:
12a-6b=35
5a-4b=7
multiply both sides
-24+12b= -70
15a-12b=21
elimiate one varibable by adding the equations
-9a= -49
divide both sides
a=49/9
subsitite the value of a
5*49/9-4b=7
solve the equation
b=91/18
a possible solution is
(a,b) = (49/9 , 91/18)

B)
362.16 cm
C)
367.59 cm
D)
376,99 cm
Answer:
[tex]A=376.99\ cm^2[/tex]
Step-by-step explanation:
We need to find the lateral surface area of the cylinder of radius 6 cm and height of 10 cm.
We need to find the lateral surface area of the cylinder. The formula for the lateral surface area of a cylinder is given by :
[tex]A=2\pi rh\\\\A=2\pi \times 6\times 10\\A=376.99\ cm^2[/tex]
So, the lateral surface area of the cylinder is [tex]376.99\ cm^2[/tex].

Below is the graph of y=f(x).
Graph y=-f(x)
Answer:
Did you attached an image? I can't see it
Step-by-step explanation:
Points can be transformed to another set of points through reflections, rotation, translation, dilations etc. The graph of [tex]y = -f(x)[/tex] is added as an attachment.
Given that:
[tex]y = f(x)[/tex]
The graph of [tex]y = -f(x)[/tex] means that, f(x) is reflected across the x-axis to get -f(x) i.e. we negate the y-values of f(x)
From the attached graph of f(x), we have the following coordinate points:
[tex](-7,0), (-5,2), (-3,0), (0,-3)[/tex]
The corresponding points on -f(x) is:
[tex](-7,0), (-5,-2), (-3,0), (0,3)[/tex]
See attachment for the graph of [tex]y = -f(x)[/tex]

Javier bought 3 bags of balloons for a party.
He used 8 balloons from each bag.
Determine how many balloons were
originally in each bag if there were 21
balloons left over.
Answer:
15 Hope this helps :)
Step-by-step explanation:
each bag has 15 balloons
21 balloon left divide that
by 3 bag cause that is the number of bags you have
So that leaves ya with 7 balloons in each bag
you already took out 8 balloons from each bag
SO ADD 8+7 .... and you get 15
The number of balls that were initially in the bag is 15
Javler bought 3 bags of balloons
He used 8 balloons from each bag
There were 21 balloons left over in the bag
= 21/3
= 7
= 7 + 8
= 15 ballons
Hence there are 15 balloons originally in the bag

Look at ABC. Points D, E, and F are the midpoints of their respective sides. Point G is the point of
concurrency for AD BE. and CF.
Which statement about point G is NOT true?
Answer:
D. Point G is the center of a circle that can be inscribe in ΔABC
Step-by-step explanation:
To inscribe implies constructing a required shape or figure within a given shape, thus touching the boundaries or sides of the given shape internally.
In the given figure if point G is used as the center of a circle, it would not form an inscribed circle in the given triangle. So that the appropriate answer is Point G is the center of a circle that can be inscribe in ΔABC. Thus, option D is not true.

CALCULUS: The general solution of the differential equation x dx - y dy = 0 is a family of curves. These curves are all
A. Hyperbolas
B. Circles
C. Parabolas
D. Ellipses
-I am thinking A, but I would like someone to please double check me. Please no wrong/fake answers. Thanks in advance & have a good one!
Answer:
A. Hyperbolas
Step-by-step explanation:
This equation is separable; you have
x dx - y dy = 0
x dx = y dy
Integrate both sides to get
1/2 x ² + C = 1/2 y ²
x ² + C = y ²
or
x ² - y ² = C
and this is indeed the equation of a hyperbola.
