Answer:

Step-by-step explanation:

We see the triangle ABC and AED with common vertex at the point A.

1. The center of dilation is the point A as it remains unchanged after dilation and the other vertices are lined up with the point A.

2. Since the scale factor is 1/2 < 1, the dilation is a smaller triangle, which is AED

Answer:

7.901. 10 '12'

Step-by-step explanation:

Answer:

1, 3, 5

Step-by-step explanation:

let the 3 consecutive odd numbers be n , n + 2 , n + 4 , then

5(n + 2) = 2(n + n + 4) + 3 ( 5 times 2nd = twice sum of 1st and 3rd + 3 )

5n + 10 = 2(2n + 4) + 3

5n + 10 = 4n + 8 + 3

5n + 10 = 4n + 11 ( subtract 4n from both sides )

n + 10 = 11 ( subtract 10 from both sides )

n = 1

n + 2 = 1 + 2 = 3

n + 4 = 1 + 4 = 5

The 3 consecutive odd numbers are 1, 3, 5

Step-by-step explanation:

let the three consecutive odd number be x + 1 , x + 3 , x + 5

a/q

5 times the middle number = 5(x + 3) is

3 more than twice the sum of 1st and 3rd number = 3 + 2(x+1 + x + 5 )

so,

= 5 ( x + 3 ) = 3 + 2 ( x + 1 + x + 5 )

= 5x + 15 = 3 + 4x + 12

= 5x + 15 = 4x + 15

= -4x + 5x = 15 - 15 = 0

= x = 0

so, the 3 consecutive odd numbers are,

x + 1 = 1

x + 3 = 3

x + 5 = 5

and also a/q

5 times the middle number = 5×3 = 15

is equal to 3 more than twice the sum of 1st and 3rd number = 3 + 2(1+5) = 12 + 3 = 15

LHS = RHS

Answer:

f(2) = -2

Step-by-step explanation:

plug in 2 to wherever x is in this statement:

f(2) = -2(2^2) - 2(2) + 10

f(2) = -2(4) - 4 + 10

f(2) = -8 - 4 + 10

f(2) = -2

Answer:

sin(-θ) = -0.809

Step-by-step explanation:

To find this, simply perform the operation that is being asked, make theta negative.

If you want to find out what theta is in the first place, do this:

θ = arcsin(0.809)

θ = 54

Then to find sin of negative theta, substitute:

sin(-θ), or, sin(-54)

should equal to:

sin(-θ) = -0.809

Answer:

[tex] \frac{1}{ {5}^{15} } [/tex]

(Answer explained)

4(x-8)+12=2(2x-9)

We move all terms to the left:

4(x-8)+12-(2(2x-9))=0

We multiply parentheses

4x-(2(2x-9))-32+12=0

We calculate terms in parentheses: -(2(2x-9)), so:

2(2x-9)

We multiply parentheses

4x-18

Back to the equation:

-(4x-18)

We add all the numbers together, and all the variables

4x-(4x-18)-20=0

We get rid of parentheses

4x-4x+18-20=0

We add all the numbers together, and all the variables

-2!=0

There is no solution for this equation

Answer:

- (x-1)^2 x (x+3)  is correct ans

Step-by-step explanation:

rewrite the expression

-x^3 - x^2 + 5x - 3

factor the expressions

x^3 + x^2 -2x^2 +2x=3x-3

factor the expression

-x^2 x (x-1)-2x x (x-1) +3 (x-1)

rewrite the expression

-(x-1) x (x^2 + 2x-3)

rewrite

-(x-1) x (x^2 + 3x - x - 3)

factor the expression

-(x-1) x (x^2+2x-3)

factor the expression

-(x-1) x (x x(x+3)-(x+3)

write in exponential form

-(x-1) x (x+3) x (x-1)

solution:

-(x-1)^2 x (x+3)

Answer:

y-intercept is -18

Step-by-step explanation:

The total y=mx+b equation is y=4x-18, you can check in a calculator. I checked on a graphing calculator, and solved it via graphing on a piece of paper.

A line is drawn on the coordinate plane that passes through the point (3,-6) and has a slope of 4. The y-intercept of the line is -18.

In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.

Given:

A line that passes through the point (x, y), with a y-intercept of b and a slope of m, can be represented by the equation,

y = mx + b.

If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,

then the equation of line is

y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)

To find the slope;

m =  (y₂- y₁) / (x₂ - x₁)

m = 4 (given)

So, the equation of the line is,

y - y₁ = m(x - x₁)    equation 1

And here

x₁ = 3 and y₁ = -6.

Substituting the values to the equation 1,

y - (-6) = 4 (x - 3)  

y+6 = 4x -12

y = 4x -18.

Comparing with the slope-intercept form,

we get y-intercept b = -18

Therefore, the equation is y = 4x -18 and y -intercept of the equation is -18
