Option A,B,C,D,F are False

Option E is True

Step-by-step explanation:

Finding graphs of the equation: y= -4x+6

Checking all the options.

A) (-4,-10)

Plugging value of x as -4 and y as -10

-10=(-4)(-4)+6

-10 = 16+6

-10 ≠ 22

So, both sides of the equation will not be equal.

B) (-4,-22)

Plugging value of x as -4 and y as -22

-22=(-4)(-4)+6

-22=16+6

-22 ≠ 22

So, both sides of the equation will not be equal.

C) (1,10)

Plugging value of x as 1 and y as 10

10=(-4)(1)+6

10 = -4+6

10 ≠ 2

So, both sides of the equation will not be equal.

D) (1,-2)

Plugging value of x as 1 and y as -2

-2=(-4)(1)+6

-2 = -4+6

-2 ≠ 2

So, both sides of the equation will not be equal.

E) (4,-10)

Plugging value of x as 4 and y as -10

-10=(-4)(4)+6

-10 = -16+6

-10 = -10

So, both sides of the equation will be equal.

F) (4,-22)

Plugging value of x as 4 and y as -22

-22=(-4)(4)+6

-22 = -16+6

-22 ≠ -10

So, both sides of the equation will not be equal.

So, Option A,B,C,D,F are False

Option E is True

Which Trig. Function do you use to find X?

zvonat [6]

Answer:

Cosine

Step-by-step explanation:

Cosine = $\frac{adjacent}{hypothenuse}$

Cos 70 = $\frac{x}{8}$

0.633 = $\frac{x}{8}$

0.633 x 8 = $\frac{x}{8}$ x 8

5.064 = x

Samantha wants to use her savings of 1150 to buy shirts and watches for her family. The total price of the shirt she bought was

ioda

Answer-

The maximum number of watches that Samantha come by with her savings is 10.

Solution-

The amount of money Samantha has in her savings account = $1150

She wants to buy shirts and watches.

Cost of one shirt = $84

Cost of each watch = $99

Let she can buy maximum of x watches, so the net price of the watches is $99x.

Then,

$\Rightarrow 99x+84=1150\\\\\Rightarrow 99x=1150-84\\\\\Rightarrow 99x=1066\\\\\Rightarrow x=\dfrac{1066}{99}\\\\\Rightarrow x=10.77$

As the number of watches can not be in fraction, so at most she can buy 10 watches.
