answer is = d=5

Step-by-step explanation:

4(3d-5) = 40

4(3d) - 4(5) = 40

12d-20 = 40

12d = 40+20

12d = 60

divide both sides by 12

d=5

The rule Rx-axis o is applied to the point (-3,-2). Where is the image in the coordinate

Nastasia [14]

Answer:

$Image = (-3,2)$

Step-by-step explanation:

Given

$Point = (-3,-2)$

Transformation = Rx-axis

Required

Determine the image

When rule Rx-axis is applied to a point (x,y),

The new coordinate point is (x,-y)

In other words, the y coordinate is negated

So, when rule Rx-axis is applied to

$Point = (-3,-2)$

The image of the point is

$Image = (-3,-(-2))$

$Image = (-3,2)$

4. solve e) 4^x-10.2^x+16=0 I think the dot means multiply?

suter [353]

$4^x-10\cdot2^x+16=0\Rightarrow(2^2)^x-10\cdot2^x+16=0\Rightarrow(2^x)^2-10\cdot2^x+16=0$

$subtitute\ 2^x=t > 0\\\\t^2-10t+16=0\\t^2-2t-8t+16=0\\t(t-2)-8(t-2)=0\\(t-2)(t-8)=0\iff t-2=0\ or\ t-8=0\\\\t=2\ or\ t=8\\\\t=2^1\ or\ t=2^3\\\\therefore\ 2^x=2^1\ or\ 2^x=2^3\\\\Answer:\boxed{x=1\ or\ x=3}$

Answer:JKL and ∠RST are complementary.

m∠JKL = 36° and m∠RST = ( x + 15)°.

Find the value of x and the measure of ∠RST .

complementary angles are two angles whose sum is 90°

36%2Bx+%2B+15=90°

51%2Bx+=90°

x+=90-51°
