Atraeus is solving the quadratic equation by completing the square. 7x^2 – 14x + 6 = 0 7x^2 – 14x = –6 A(x^2 – 2x) = –6 What is the value of A?

Answers

Answer 1

Answer: Hello,

A=7
Indeed
A(x²-2x)=-6
7x²-14x=-6

==>A=7 and -14=-2A==>A=7

Which points are solutions to the linear inequality; y < 0.5x + 2?

Answers

Answer:

A) $(-3,-2)$

C) $(-1,-2)$

E) $(1,-2)$

F) $(1,2)$

Step-by-step explanation:

we have

$y<0.5x+2$

The options are the points

$(-3,-2)$ , $(-2,1)$ , $(-1,-2)$ , $(-1,2)$ , $(1,-2)$ , $(1,2)$

we know that

If a ordered pair is a solution of the inequality

then

the ordered pair must be satisfy the inequality

Verify

Point A) $(-3,-2)$

Substitute the value of x and value of y in the inequality an compare

$-2<0.5(-3)+2$

$-2<0.5$ -------> is true

The ordered pair $(-3,-2)$ is a solution of the inequality

Point B) $(-2,1)$

Substitute the value of x and value of y in the inequality an compare

$1<0.5(-2)+2$

$1<1$ -------> is not true

The ordered pair $(-2,1)$ is not a solution of the inequality

Point C) $(-1,-2)$

Substitute the value of x and value of y in the inequality an compare

$-2<0.5(-1)+2$

$-2<1.5$ -------> is true

The ordered pair $(-1,-2)$ is a solution of the inequality

Point D) $(-1,2)$

Substitute the value of x and value of y in the inequality an compare

$2<0.5(-1)+2$

$2<1.5$ -------> is not true

The ordered pair $(-1,2)$ is not a solution of the inequality

Point E) $(1,-2)$

Substitute the value of x and value of y in the inequality an compare

$-2<0.5(1)+2$

$-2<2.5$ -------> is true

The ordered pair $(1,-2)$ is a solution of the inequality

Point F) $(1,2)$

Substitute the value of x and value of y in the inequality an compare

$2<0.5(1)+2$

$2<2.5$ -------> is true

The ordered pair $(1,2)$ is a solution of the inequality

How do I round 35.26 to the nearest whole
number

Answers

The rounding off the nearest number gives 35.

What is rounding of a number?

A rounded number has about the same value as the number you start with, but it is less exact.
If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up. Example: 38 rounded to the nearest ten is 40.
If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down. Example: 33 rounded to the nearest ten is 30.

Given is the number 35.26.

We have the number as -

35.26

Rounding off, we get -

35.26

35.3

Therefore, the rounding off the nearest number gives 35.

The rounded number to nearest whole number of 35.26 will be 35.

This is because we consider lower limit if the decimal is lower than 5, and consider the upper limit when the decimal is greater than 5.

a square rotated about its center by 360° maps on to itself at (1, 2, 3, or 4) different angles of rotation.

Answers

A square rotated around its center maps onto itself every 90° of rotation.
If you rotate it a full 360°, then that happens 4 times.

Answer: no rotation because only reflections through the center of a square can map it onto itself

AssignmentYeshi is making Pork fing. He has only 300g of pork
So he have to adjust the ro recipe.
500g pork
150g tomatoes
100g butter
120ml water
45g green chilli
8og onion.
a How much of each of the other ingredients
should he use to make pork fing

Answers

Answer / Step-by-step explanation:

500g - 300g = 200 {200 ÷ 500 = 0.4} ---- 300g pork

0.4 × 150g = 60g tomatoes

0.4 × 100g = 40g butter

0.4 × 120ml = 48ml water

0.4 × 45g = 18g green chilli

0.4 × 8og = 3.2og onion

Given: ABCD is a parallelogram.Prove: ∠A and ∠D are supplementary.

Parallelogram A B C D is shown.

By the definition of a parallelogram, AB∥DC. AD is a transversal between these sides, so ∠A and ∠D are
angles. Because AB and DC are
, the same-side interior angles must be
by the same-side interior angles theorem. Therefore, ∠A and ∠D are supplementary.
