PLEASE HELP ME!!!!!!!!

Mathematics
1 answer:
Reil [10]3 years ago
7 0

Answer:

You are correct, the answer is (y=3)=-2(x-8)

Step-by-step explanation:

For this problem, let's first make the equation of the perpendicular line be in slope intercept form. Add 4y to both sides.

2x=4y+7

Subtract 7.

2x-7=4y

And divide by 4.

y=1/2x7/4

Here, the slope is 1/2, so the slope of the perpendicular line is the negative reciprocal, or -2.

Finally, substitute the given point into the point slope formula to get (y+3)=-2(x-8)

Dan earns £9.30 per hour. How much will he earn for 9 hours work?
Dimas [21]

Answer: £83.70

Step-by-step explanation:

We can set up a ratio.

Let x be the amount he earns for 9 hours of work.

\frac{9.30 pounds}{1 hour} = \frac{x pounds}{9 hours}

We can cross multiply:

x = 9*9.3

x = £83.70

Given that angleAXB is complementary to both angleCYD and angleFZE, and mangleAXB = 20°, what is mangleCYD + mangleFZE?
EastWind [94]
Complementary angles add up to 90 degrees. We know that AXB is 20 degrees, and AXB is complementary to CYD and FZE. So CYD and FZE are 90-20, so each angle is 70 degrees
CYD = 70 degrees
FZE = 70 degrees
CYD + FZE = 70 + 70 = 140

Clara has a lawn in front of her house as mapped on the coordinate plane. She wants to plant a bed of flowers between the points
Ronch [10]

Answer:

Look Below In the Explanation

Step-by-step explanation:

Point P has coordinates of (4,4) and point Q has coordinates of (4,-4).

Since both points have the same x-coordinates we can subtract point Q's y-coordinate from point P's y-coordinate.

I will set the equation up and try and figure this part by yourself. I hope you learned what to do from previous questions that are very similar to this that I answered.

4 - ( -4) = length of the bed of flowers

Hope that helps and maybe earns a brainliest!

Have a splendid day! :^)
