Answer:

the answer would be 5 units for x

Step-by-step explanation:

you would take the x and put it over 10 and then take 10 over 4x and then you would have to cross multiply which would give you 4x^2 =100 and then you would divide 100 by 4 which would give you 24 and then you need to take the square root of 25 which is 5

Answer:

$\huge{ \boxed{ \bold{ \sf{y = - 2x + 6}}}}$

☥ $\tt{Question} :$

Write the equation of a line in slope - intercept form that has a slope of -2 and passes through the point ( - 1 , 8 ).

☥ $\tt{Step - \: by \: - \: step \: explanation}$

☪ $\underline{ \underline{ \text{Given : }}}$

Slope ( m ) = -2
Given point = ( - 1 , 8 )

☪ $\underline {\underline{ \text{To \: find}}} :$

Equation of a line in slope - intercept form ( i.e y = mx + c )

Let the point ( -1 , 8 ) be ( x₁ , y₁ )

☪ $\underline{ \underline{ \text{Solution}}} :$

$\underline{ \sf{y - y1 = m(x - x1)}}$

plug the known values :

↦ $\text{y - 8 = - 2 \{ x - ( - 1) \} }$

↦ $\text{y - 8 = - 2(x + 1)}$

Distribute -2 through the parentheses :

↦ $\text{y - 8 = - 2x - 2}$

Transpose 8 to right hand side and change it's sign

↦ $\text{y = - 2x - 2 + 8}$

↦ $\boxed{ \text{y = - 2x + 6}}$

And we're done !

Hope I helped!

DO,H = (7, 9) (14, 18) The scale factor is _____. 1/2 2 4 7/9

lana [24]

ANSWER

The scale factor is 2.

EXPLANATION

The point H(7,9) is dilated about the origin and the image is (14,18).

Let the scale factor be k.

Then,

$(7,9)\to (7k,9k)$

Comparing to the given image, we have:

$(7k,9k) = (14,18)$

This implies that,

$7k = 14$

Divide by 2

$k = 2$

Or

$9k = 18$

$k = 2$
