Answer with Step-by-step explanation:

We have to determine which of the following points (-1,5), (1,5), (0,-5) and (0,5)

is the solution of 5x-2y=10

i.e. on putting the values of x and y in 5x-2y we must get 10

(-1,5)

5×(-1)-2×5 = -15 ≠ 10

Hence, it is not the solution of 5x-2y=10

(1,5)

5×1-2×5 = -5 ≠ 10

Hence, it is not the solution of 5x-2y=10

(0,-5)

5×0-2×(-5) = 10

Hence, it is the solution of 5x-2y=10

(0,5)

5×0-2×5 = -10 ≠ 10

Hence, it is not the solution of 5x-2y=10

Hence, Solution to the equation is:

(0, -5)

The right answer to this is (0,-5). If you substitute the points into the equation, it will give the answer 10.
$5x - 2y = 10 \\ let x = 0 \\ let y = -5 \\ \\ 5(0) - 2(-5) =10 \\ 10 = 10$

The points (0,-5) satisfy the equation because both sides of the equation is equal to 10.

COMPLETING THE SQUARE<br> X^2– 2x +

Studentka2010 [4]

Answer:

x^2 -2x + 1

Step-by-step explanation:

Think of a quadratic equation as

ax^2 + bx + c

x^2 -2x +

Comparing the two equations

a = 1 , b = -2, c = ?

c becomes the missing part

Divide b by 2

-2/2 = -1

square the result

-1^2

= 1 this is what to add to get a perfect square

x^2 -2x + 1

(x - 1)^2

Probally d most likely because if you know what the deer looks like it is orange and white spots so it is more manipulating the light from the leaves. If im wrong then its A

Which inequality represents the sentence below? The difference of a number and one and four tenths is more than nine and seventy

Marianna [84]

The inequality represents the sentence below is that the p minus 1. 4 greater-than 9.

<h3>What is the inequality equation?</h3>

Inequality equation is the equation in which the two expressions are compared with greater than, less than or other inequality signs.

Given that the difference of a number and one and four tenths is more than nine and seventy-eight hundredths.

Before solving it, first let's discuss the tenth and hundredths,

Tenth is written as the fractional part of the number 10. The value of one tenth is equal to 1/10 or 0.1.
Hundredths is written as the fractional part of the number 100. The value of one hundredth is equal to 1/100 or 0.01.

Here, the sentence given that the difference of a number and one and four tenths is more than nine and seventy-eight hundredths.

One and four tenths can be written as,

$1\dfrac{4}{10}$

Nine and seventy-eight hundredths can be written as,

$9\dfrac{78}{100}$

Let suppose the number is <em>p</em>. This difference of this number and one four tenths is more than nine and seventy-eight hundredths. Thus,

$p-1\dfrac{4}{10} > 9\dfrac{78}{100}\\p-\dfrac{14}{10} > \dfrac{978}{100}\\p-1.4 > 9.78\\$
