D is the answer as the both have solution x=-2 y=3
14x=-28       12(-2)-3y=-33
x=-2              -3y=-9
                       y=3
from the given equation
4x-y=11 eq 1
2x+3y=5 eq 2
x=y-11/4 from equation 1
subsitute this value of x in equation 2
2(y-11/4)+3y=5
y-11+6y=10
7y-11=10
y=3
subsitude this value of y in equation (x=y-11/4)
so x= -2 
thus same solution so ANSWER IS D

S = ut+ 16t²<br>Find the value of s when u = 2 and t = 3.​
Fed [463]

Answer:

<h2>150</h2>

Step-by-step explanation:

Given,

u = 2

t = 3

Now, Finding the value of s

s = ut \:  + 16 {t}^{2}

Plugging the values of u and t

s = 2 \times 3 + 16 \times  {( 3)}^{2}

Calculate

s = 2 \times 3 + 16 \times 9

s = 6 + 144

Calculate the sum

s = 150

Hope this helps ..

Good luck on your assignment..

icang [17]

Answer:

\huge\green{ \mid{ \underline{ \overline{ \tt  ♡ ANSWER ♡ }} \mid}}

x = 40

(6 - 2x)(3 - 2x) \\  =( 6 - 2 \times 40)(3 - 2 \times 40) \\  = (6 - 80)(3 - 80) \\  =  - 74 \times  - 77 \\  = 5698

How do I solve for X?
lidiya [134]
We use the theory of Pythagoras because the triangle is right.

AB {}^{2}  =  AC {}^{2}  +  BC {}^{2}
since AB = AC = x
8 {}^{2}  = x {}^{2}  + x {}^{2}
64 = 2x {}^{2}
32 = x {}^{2}
x =  \sqrt{32}
x =  \sqrt{16 }  \times  \sqrt{2}
x = 4 \sqrt{2}

The sum of the first three terms of geometric sequence is 14. If the first term is 2, find the possible values of the sum of the
Irina18 [472]

Geometric series are in the form of

a +a*r +a*r^2+...

Where a is the first term and r is the common ratio .

And it is given that

2 +2*r +2*r^2=14

2r^2+2r-12=0

r^2 +r-6=0

(r+3)(r-2)=0

r=-3,2

So the first five terms are

2+2(-3)+2(-3)^2+2(-3)^3+2(-3)^4  or 2+2(2)+2(2)^2+2(2)^3+2(2)^4

= 2-6+18-54+162 or 2+4+8+16+32

= 122 or 62
