Answer with explanation:

The number in which we have to add a number to give irrational = 0.5

$0.5=\frac{5}{10}\\\\=\frac{1}{2}$

is a Rational Number as the decimal expansion terminates or denominator contains the number in the form of $2^n \text{or} 5^m \text{or} 2^n \times 5^m$ .

→Sum of two Rationals Can't be a Irrational Number.

→Sum of Rational And Irrational is Irrational.

So, if you add any Irrational number like √2,π,∛2 to , 0.5 , it will give an Irrational Number.

⇒0.5 +Irrational Number=Irrational Number

A) is 2x
b) is $x^{3}$
c) is -2x

I think these are correct.
$log_{10}1000^{x] = log_{10}10^{2x}=2x$
I did similar things to get other answers
$1000^{log_{10}x} = 10^{3log_{10}x}=10^{log_{10}x^{3}}=x^{3}$

Stewart School has 178 computers. Grade 3 has 58 computers and flgrade 4 has 57 computers. What equations can be used to find ho

Ilya [14]

Answer: $x=58+57=115$

$y=178-115=63$

Step-by-step explanation:

Let x be the number of computers Grade 3 and grade 4 has and y be the numbers of computers the rest of school has.

Then, x= Grade 3 computers +Grade 4 computers.

$\Rightarrow\ x=58+57=115$

And y = Total computers - x

$\Rightarrow\ y=178-115=63$

Therefore, The equations can be used to find how many computers the rest of the school has.

$x=58+57=115$

$y=178-115=63$

I need this answer step by step but if you can't that's fine too!

Naily [24]

Since the scale factor is 0.5, it means that you have to divide in half each side.
x= 7/2= 3.5
y= 12/2= 6
z= 6/2= 3.25

Given A(2, 3), B(8, 7), C(6, 1), which coordinate will make line AB perpendicular to line CD?

nadezda [96]

Answer:

The correct option is;

D(4, 4)

Step-by-step explanation:

The given coordinates of the points are, A(2, 3) B(8, 7), C(6, 1), therefore, the coordinates of the point D that will make CD perpendicular to AB will have a slope = -1/m, where, m = the slope of the line segment AB

The formula for finding the slope, m, of a segment, given the coordinates of two points on the straight line segment (x₁, y₁), (x₂, y₂)

$Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Therefore, for, the segment AB, we have;

m = (7 - 3)/(8 - 2) = 4/6 = 2/3

m = 2/3

Therefore, to make the segment AB perpendicular to the segment CD, the slope of the segment CD will be -1/m = -1/(2/3) = -3/2

The equation of the segment CD in point and slope form is therefore;

y - 1 = -3/2×(x - 6)

y - 1 = -3·x/2 + 9

The standard form of the equation of the segment CD is therefore;

y = -3·x/2 + 9 + 1 = -3·x/2 + 10

y = -3·x/2 + 10

The point that satisfies the above equation is the point (4, 4) because;

4 = -3 × 4/2 + 10

The correct option is therefore, D(4, 4).
