Hello could someone solve this please? The answer is: x = -1 or x = -2/25.
I would like a step by step solution please
Answers
Answer: the answer only -2/25
Step-by-step explanation:
[tex](5x + 3)^{2}= (\sqrt{3x+7} )^{2}[/tex]
[tex]25x^{2} +30x++9 = 3x+7[/tex]
[tex]25x^{2}+27x+2=0[/tex]
[tex](x+1)(25x+2)=0[/tex]
[tex]x=-1 , -\frac{2}{25}[/tex]
Check
[tex]x=-1[/tex]
[tex]5(-1)+3 =\sqrt{3(-1)+7}[/tex]
[tex]-2 =2[/tex]
The equality is false.
[tex]x=-\frac{2}{25}[/tex]
[tex]5(-\frac{2}{25} )+3 =\sqrt{3(-\frac{2}{25} )+7}[/tex]
[tex]\frac{13}{5}= \frac{13}{5}[/tex]
The equality is true.
[tex]x\neq -1[/tex]
[tex]x=-\frac{2}{25}[/tex]

3x + y = 8
x - 3y = 11
Answers
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

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)

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 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?
Answers
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.
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
Answers
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

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

→ 9(x-6)+41 = 75. Transposing the like terms.
→ 9(x-6) = 75 - 41 Performing subtraction of the term in RHS
→ 9(x-6) = 34 Performing multiplication in LHS.
→ 9x - 54 = 34 Distributive property
→ 9x = 34 + 54 Performing addition of the term in RHS.
