Answer:

±5

Step-by-step explanation:

Given equation ,

=> x² - 25 = 0

=> x² - 5² = 0

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

=> x = ±5

Answer:

x = -5 or 5

Step-by-step explanation:

→ Factor the quadratic

( x + 5 ) ( x - 5 )

→ Equate each bracket to 0

x + 5 = 0 and x - 5 = 0

→ Solve each for x

x = -5 or 5

Answer:

0.03 or [tex]\frac{3}{100}[/tex]

Step-by-step explanation:

Remember to do PEMDAS. Parentheses, Exponents, Multiplication, Division, Addition, Subtraction. That is the order and equation is done in. So, -3/10 (if this is a fraction) gets you -0.3. Then multiply that by (-0.10) to get 0.03 or 3/100.

[tex]\boxed{y = -5,5x - 52}[/tex]

Step-by-step explanation:

Equation of a straight line: y = kx + b

Points: (-10,3) and (-8,-8)

Сompose the system of equations:

[tex]\displaystyle \left \{ {{3=-10k + b} \atop {-8=-8k + b}} \right[/tex] [tex]\displaystyle \left \{ {{b= 3 + 10k} \atop {b=8k - 8}} \right \Longrightarrow 3 + 10k = 8k - 8[/tex]

[tex]3 + 10k = 8k - 8[/tex]

[tex]2k = -11|:2[/tex]

[tex]k = -5,5[/tex]

[tex]b = 3 + 10k = 3 + 10 \cdot ( -5,5) = 3 - 55 = -52[/tex]

Answer:

the answer is x=-1

Step-by-step explanation:

The required solution to the given equation 5x + 1.2 = −3.8 is x = - 1.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

The equation is given in the question below as:

5x + 1.2 = −3.8

We have to determine the solution to the given equation 5x + 1.2 = −3.8

⇒ 5x + 1.2 = −3.8

Rearrange the terms of non-variable in the above equation,

⇒ 5x =  - 3.8 - 1.2

Apply the addition operation,

⇒ 5x = -5

Divided by 5 both sides of the above equation,

⇒ x = -5 / 5

Apply the division operation,

⇒ x = - 1

Therefore, the required solution to the given equation 5x + 1.2 = −3.8 is x = - 1.

Answer:

$5.25

Step-by-step explanation:

The cost of 7 oranges is $5.25

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

for example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given;

Cost of 3 Oranges= 2.25

So, the cost of 1 orange= 2.25 / 3

                                       = 0.75

Now, the cost of 7 oranges

= 0.75 x 7

= $5.25

Hence, the cost of 7 oranges is $5.25
