Answer:

x = ± \frac{3}{5}

Step-by-step explanation:

Given

25x² + 1 = 10 ← subtract 10 from both sides

25x² - 9 = 0 ← in standard form

note that 25x² - 9 is a difference of squares and factors as

(5x - 3)(5x + 3) = 0

Equate each factor to zero and solve for x

5x - 3 = 0 ⇒ 5x = 3 ⇒ x = \frac{3}{5}

5x + 3 = 0 ⇒ 5x = - 3 ⇒ x = - \frac{3}{5}

Please help I’m really confused. I will give BRAINLIEST!
stiv31 [10]

Answer:

t = 115

s = 60

g(x) = 10/23x - 10

Step-by-step explanation:

find s first since its easy (it goes up by 10's)

then take a pair from the table that corresponds such as 69 for x and 30 for g(x) and turn them into a fraction:

69/30

do the same for t:

t/50

equal 69/30 to t/50 and solve using cross multiplication:

69/30 = t/50 =  

30t = 3450

/30      /30

t = 115

honestly had a little hard time finding the equation but basically I simplified the fraction 30/69 to get 10/23 for slope and then I insert a corresponding x and y value into y= mx+b with the slope value to find b.

What is 1+2?????????????????
irina1246 [14]

Answer:

3

if a  is 1 more than b it can be expressed as so:

a=b+1

b+1=a

b^2+1=a^2

b^2=a^2-1

b=a-1

if b if 1 then a is 2

b+1=a

-a+b=-1

a-b=1

a=2, b=1

a=b+1

a+b=3

1+2=3
