Calculate y when x = 5

Y=2x+3

Answers

Answer 1

Answer:

Answer: y=13

Step-by-step explanation:

$y=2(5)+3\nmultiply\ny=10+3\nadd\n10+3=13\ny=13$

Answer 2

Answer:

y=13

Step-by-step explanation:

given that,

x=5

to find,

y=2x+3, when x=5

substitute 5 in the place of "x" we get,

y=2×5+3

according to BODMAS rule( bracket of division multiplication addition and subtraction) first we have to multiply 5 with 2 and then add the product with 3 we get,

y=10+3

y=13

783 rounded to the nearest hundred is

Answers

Answer:

Rounded to the nearest hundred is 790.

Step-by-step explanation:

Given : Number 783.

To find : Number rounded to the nearest hundred ?

Solution :

Nearest hundred means,

When the digit at tens place is greater than or equal to 5 then the number round by 1 and rest became zero.

When the tens digit place is less than 5 then the number remain same and rest became zero.

Number 783.

Tens place is 8 >5 so it round by adding 1,

$783\approx 790$

Therefore, Rounded to the nearest hundred is 790.

783 rounded to the nearest hundred is 800

To round 783 to the nearest hundred,

Since we know that,

A mathematical process known as "round off nearest hundred" involves rounding a number to the nearest hundred. The final two digits of the number will be examined, and we will round them to the closest hundred.

Look at the digit in the tens place, which is an 8.

Because 8 is greater than or equal to 5,

Round up to the nearest hundred.

To do this, we add 1 to the digit in the hundreds place, which is 7,

and change the digits in the tens and ones places to 0.

So, 783 rounded to the nearest hundred is 800.

Answers

x² - 24x + c

perfect square trinomial: a² + 2ab + c²
a² = x² ⇒ x * x
2ab = -24x ⇒ 2(-12)x
c² = (-12)² = 144

x² - 24x + 144

The value of c to create a perfect square trinomial is 144.

Answer:

How to find the perimeter and the area of a rectangle on a coordinate plane using the distance formula? : A(3,8) B(5,4) C(-4,-1) D(-6,3) Round to the nearest tenth if necessary.

Answers

I used some site to plot the points.

First, let's recall the formulas for Perimeter and Area of a Rectangle.
Perimeter = 2(l+w)
Area = l×w
Also, the distance formula is
D = $\sqrt{( x_(2)-x_(1))^2+{(y_(2)-y_(1))^2}$

Now, we need to determine l and w.
So, the length is the distance of AD or BC
and the width is the distance of DC or AB
(I'll just use the sides that I've labelled for ease)

So first to determine the length, we need to calculate the distance of AD
Points are A(3,8) and D(-6,3)
$x_(1) =3, x_(2) =8, y_(1) =6, y_(2) =-3$
$D_(AD)= \sqrt{( 6-3)^2+{(-3-8)^2}$
$D_(AD)= √((3)^2+(-11)^2)$
$D_(AD)= √(9+121)$
$D_(AD)= √(130) ≈ 11.40$
So the length of the rectangle is 11.40 units.

Now, the width!
So first to determine the width, we need to calculate the distance of DC
Points are D(-6,3) and C(-4,-1)
$x_(1) =6, x_(2) =-4, y_(1) =-3, y_(2) =-1$
$D_(DC)= \sqrt{(-4-6)^2+{(-1- -3)^2}$
$<span>D_(DC)= \sqrt{(-4-6)^2+{(-1+3)^2}$
$D_(DC)= √((-10)^2+(2)^2)$
$D_(AD)= √(100+4)$
$D_(AD)= √(104) ≈ 10.20$
So the width of the rectangle is ≈10.20 units.

Let's now solve for Perimeter and Area using
l = 11.40
w = 10.20

Perimeter = 2(l+w)
Perimter = 2(11.40+10.20)
Perimter = 2(21.60)
Perimter = 43.2 units

Area = l×w
Area = (11.40)(10.20)
Area = 116.28
Area = 116.3 units² (rounding)

In conclusion, given points A(3,8) B(5,4) C(-4,-1) D(-6,3), the Perimeter is 43.2 units and the Area is ≈116.3 units² using the distance formula.

Jackie scored 82 and 88 on her first two quizzes. Write and solve a compound inequality to find possible values for a third quiz score that would give her an average between 80 and 85, inclusive.a. 80 <= 82 + 88 + n / 3 <= 85; 70 <= n <= 85

b. 70 <= 82 + 88 + n / 3 <= 85; 80 <= n <= 85

c. 80 <= 82 + 88 + n / 3 < 85; 70 < n < 85

d. 82 <= 80 + 85 + n / 3 <= 88; 70 <= n <= 85

Answers

Answer : option A

Jackie scored 82 and 88 on her first two quizzes

Let n be the score of third quiz

Average of 3 quiz = $(82+88+n)/(3)$

average between 80 and 85, inclusive.

so average lies between 80 and 85

Question says 80 and 85 inclusive. so we use <= or >= symbol

So inequality becomes

$80<= (82+88+n)/(3) <= 85$

$80<= (170+n)/(3) <= 85$ ( multiply all sides by 3)

$240<=170+n<= 255$ (subtract all sides by 170)

$70<=+n<= 85$

so option A is correct

the answer is a . first you can understand that b and d can not be the answers because the question says that hey score should be between 80 and 85 so between a and c the answer is a :)))
