DedPeter [7]3 years ago

Answer:

x=2

Step-by-step explanation:

2.1(2.3 + 2.1x) = 11.65 + x

Distribute

4.83+4.41x=11.65+x

bring 4.83 over (-)

4.41x=6.82+x

bring x over

4.41x-1(x)=6.82

4.41-1=3.41 so

3.41x=6.82

divide 3.41

x=2

Answer:

For the parallelogram to be a rectangle, at least one angle must be a right angle or a 90° angle, we know that:

    13x + 34° + 10x + 10° = 90°

=> 13x + 10x                   = 90° - 34° - 10°

=> 23x                            = 46°

=> x                                 = 46°/23 = 2°

Sonja [21]
The correct answer for this question is this one: "Roughly 1.7 meters."

The height is 828 meters tall. The scale model is 1 meter is equal to 500 meters.

To the nearest tenth, Brody's model of the Burj Khalifa should be
= 828 / 500
= 1.656 meter
Roughly 1.7 meters.


Hope this helps answer your question and have a nice day ahead.

Answer:

Answer is option b)

<em>Answer is </em><em>given below with explanations</em><em>. </em>

Step-by-step explanation:

a \: walking \: path \: is \: represented \: by \:  \\ y =  - 4x - 6 \\ 4x + y + 6 = 0 \\ given \: that \\ a \: new \: path \: will \: be \: built \: perpendicular  \\ \: to \:  \: the \: walking \: path \\ the \: equation \: of \: the \: line \: perpendicular \: to \\ 4x + y + 6 = 0 \: is \\ x - 4y + k = 0 \\ since \: it \: passes \: through \: ( - 4,10) \\ substitute \: x \:  =  - 4\: and \: y = 10 \: in \: required \: equation \\  - 4 - 4(10) + k = 0 \\ k = 44 \\ then \: the \: equation \: is \\ x - 4y + 44 = 0 \\ adding \: 4y \: on \: both \: sides \\ x + 44 = 4y \\ dividing \: by \: 4 \: on \: both \: sides \\ y =  \frac{x}{4}  + 11 \\ y =  \frac{1}{4} x + 11 \\ so \: the \: answer \: is \: option \: b) \:   \frac{1}{4} x + 11

Write the equation of a line that is perpendicular to y = 5 y=5y, equals, 5 and that passes through the point ( − 7 , − 5 ) (−7,
Jlenok [28]
The line of the equation perpendicular to y=5 and cuts through (-5,-7) will be given by
m(x-x1)=y-y1
where m=slope.
from y=0x+5, the slope of the perpendicular line m=0,
thus the equation will be:
0(x--5)=y--7
0=y+7
y=-7
The equation is y=-7

RoseWind [281]

Answer:

I believe the correct answer would be A.) Profit.

Step-by-step explanation:

This is because <em>revenue</em> is the amount earned, which, in this case is $100,000. Loss is not a proper term. The proper term would be <em>expense. </em>This is the amount spent or lost. The correct answer would be <em>profit. </em>Profit just means the amount left after the expenses have been deducted from the revenue.

Hope this helps,
