solve the simultaneous equation
3x + y = 8
x - 3y = 11
Answer:
x = 7 / 2, y = - 5 / 2
Step-by-step explanation:
3x + y = 8 ------> equation 1
3 ( 3x + y = 8 )
9x + 3y = 24 ------> equation 2
x - 3y = 11 ------> equation 3
Add equations 2 & 3,
9x + 3y = 24
x - 3y = 11
_________
10x + 0 = 35
10x = 35
x = 35 / 10
x = 3.5
Substitute x = 3.5 in equation 1,
3x + y = 8
3 ( 3.5 ) + y = 8
10.5 + y = 8
y = 8 - 10.5
y = - 2.5
x = 3.5
= 35 / 10
x = 7 / 2
y = - 2.5
= - 25 / 10
y = - 5 / 2
The students were helping decorate a bulletin board for the missionary conference. Christi use 5/16 of a roll of blue paper and sandy used 1/8 of the roll. How much more paper did Christi use than sandy?
Answer:
Christi used 3/16 more of the roll than Sandy did.
Step-by-step explanation:
First, you'll need to make the denominators the same. I htink it's called GCF or Greatest common factor.
16:16,32...
8:8,16...
That was quick, anyways now perform these equations:
1/8=8 x 2 = 16, 1 x 2 = 2
1/8 is now 2/16. Now you can easily compare the equations.
Since 5/16 already has 16 as it's denominator you make no changes to it.
5/16 - 2/16 = 3/16
now you can simplify your answer: 3/16 = 3/16 it's already at it's simplest form.
Your answer would be 3/16.

Let's use the furthest left point on the triangle to figure out the translation.
Blue triangle = (-5,1)
Black triangle = (-3,-1)
To get from -5 to -3 we moved the triangle 2 units to the right, which means that we added 2.
To get from 1 to -1, we moved the triangle 2 units down, which means we subtracted 2.
Rule: {2, -2}

The x-intercepts and vertex of the quadratic relation y = –(x + 3)(x + 5) are:
a) x-intercepts are 3 and 5; vertex is (4, 0)
b) x-intercepts are –3 and –5; vertex is (–4, 9)
c) x-intercepts are 3 and 5; vertex is (4, –63)
d) x-intercepts are –3 and –5; vertex is (–4, 1)
Answer:
d) x-intercepts are –3 and –5; vertex is (–4, 1)
Step-by-step explanation:
parabola are the vertex findings -4
we find these using formula m +n / 2
m+ n = -3 -5 / 2 = -4
m+n / 2 = -8/2 = -4
xv = -4
plug in -4 to find yv
(x+5)
(-4 + 5)
yv = 1
A submarine travels 8.3 km due North from its base and then turns and travels due West for 13.9 km.
How far away is the submarine from its base?
Give your answer rounded to 1 DP
Answer:
He is 5.6 km away
Step-by-step explanation:
he starts traveling away from base and is 8.3 km away to start with
then he turns west and travels 13.9 km away
what this mean is that you have to subtract the distance he turned from the distance he started off with
ex: 13.9 - 8.3 = 5.9
to get your answer of how far away he is from the base

QUESTION: b(a-6)
Answer:
5 – 6 (b + 1) = 5 + ( – 6 ) × b + (– 6) × 1 = 5 – 6b – 6 = – 6b – 1. Example 1: Simplify: 5(a – 4) + 3 = 8.
explanation: your welcome
Step-by-step explanation:
what do you mean ? you need to multiply this out ? or what is the problem ?
just to multiply this :
b(a-6) = ba - 6b
or with full symbols for operations
b×(a-6) = b×a - 6×b
In ∆ABC , if AB = AC and ∠B=80° then ∠C is equal to
a) 20° b) 40° c) 60°
Answer:
Here,
given, angle B = 80 degree
in ABC triangle, AB = AC
that means angle B = angle C
so angle C must be 80 degree
Step-by-step explanation:
I guess, the options are wrong
or,
may the question asked for angle angle A
which will be = 180- (80+80) = 180 - 160 = 20 degree (option a)

WILL MARK BRAINLEIST
Answer:
Step-by-step explanation:
a^2 + b^2 = c^2
3.2^2 + b^2 = 18.9^2
10.24 + b^2 = 357.21 Subtract 10.24 from both sides
b^2 = 357.21 - 10.24
b^2 = 346.97
sqrt(b^2) = sqrt(346.97)
b = 18.62
Perimeter = 2*a + 2*b
Perimeter = 2*3.2 + 2*18.62
Perimeter = 6.4 + 37.25
Perimeter = 43.65

A regular octagon is shown below. Suppose that the octagon is rotated clockwise about its center so that the vertex at Y is moved to 7. How many degrees
does the octagon rotate?
Answer:
I believe it says the vertex at Y is moved to T:
the angle of each side changes by 360 / 8 = 45 at each vertex
If 3 vertices separate Y and T the the total rotation would be
3 * 45 = 135 deg
The octagon rotated 135 degree.
What is an Octagon?An octagon is a polygon with eight sides.
The total angle at the center is 360 degree and for a regular octagon, the angle made by each side is equal to 360/8 = 45 degree.
The octagon STUVWXYZ is rotated clockwise such that, the vertex Y moves to T.
Movement of Y to T is moving 3 steps clockwise
= 45* 3
= 135 degree
