Evaluate:
4x/(5-3)

Answers

$(4x)/(5-3)$

Subtract the numbers : $5 - 3 = 2$

$= (4x)/(2)$

Cancel the common factor : 2

$(4x)/(2) = 2x$

hope this helps!.

$(4x)/(5-3)$

5 - 3 = ?

5-3 = 2

$(4x)/(2)$

4/2 = 2

Simplified.

$2x$

Final answer: 2x

Find an equation for the line that passes through the point (-3, 6), parallel to the line through the points (0,-7) and (4,-15). Write your answer in point-slope form.

Answers

1st we will have to find the equation of the points (0,-7)(4,-15)
find the slope 1st
slope = y2-y1/x2-x1
slope = -8/4
slope = -2
and we know that the y intercept is -7
thus
the equation would be
y = -2x - 7

now we need to find the equation of the line that passes throgh (-3,6) and parallel to the previous equation
since it is parallel to the previous equation then they have the same slopes
thus the slope is -2
now we need to use
y - y1 = m(x - x1) to determine the equation
subsitute the values of x1 and y1
and m is the slope
y - 6 = -2(x +3)
y - 6 = -2x -6
y = -2x
that's the equation!

PLEASE HELP ASAP!Rosemary is cutting 3 wooden sticks to build part of a kite frame. The part she is building must be a right triangle. Which choice below could be the lengths, in inches, of the sticks rosemary cut?

A. 6, 8, 10.
B. 2, 5, 10.
C. 5, 6, 7.
D. 2, 3, 5.

Answers

Using the Pythagorean Theorem, it is found that the lengths could be given by:

A. 6, 8, 10.

What is the Pythagorean Theorem?

The Pythagorean Theorem relates the length of the legs $l_1$ and $l_2$ of a right triangle with the length of the hypotenuse h, according to the following equation:

$h^2 = l_1^2 + l_2^2$

Hence, in item a:

$h^2 = 6^2 + 8^2$

$h^2 = 100$

$h = 10$

So it is a right triangle.

Item b:

$h^2 = 2^2 + 5^2$

$h^2 = 29$

$h = √(29) \neq 100$

It is not a right triangle.

Item c:

$h^2 = 5^2 + 6^2$

$h^2 = 61$

$h = √(61) \neq 7$

It is not a right triangle.

Item d:

$h^2 = 2^2 + 3^2$

$h^2 = 13$

$h = √(13) \neq 5$

It is not a right triangle.

Hence option a is correct.

A is probably the correct answer

What is the sign of the product (−4)(6)(9)(3)? Positive, because the products (−4)(6) and (9)(3) are negative and the product of two negative numbers is positive

Positive, because the products (−4)(6) and (9)(3) are positive and the product of two positive numbers is positive

Negative, because the product (−4)(6) is negative and the product (9)(3) is positive, and the product of a negative number and a positive number is negative

Negative, because the product (−4)(6) is negative and the product (9)(3) is negative, and the product of two negative numbers is a negative number

Answers

Hello,

The correct answer is C) Negative, because the product (-4)(6) is negative and the product (9)(3) is positive, and the product of a negative number and a positive number is negative.

Hope this helps!!!!

The product is -648. This is because (-6)(4) is a negative product and (9)(3) is a positive product. A negative and a positive product equals a negative outcome. The third option is correct
