Answer:
The third choice is the one you want
Step-by-step explanation:
If we are to write the equation of a line perpendicular to WX, we first must determine what the slope of the WX is, because the line perpendicular to WX has a slope that is the flip of the slope of WX with the opposite sign. Solving for y takes care of finding the slope of WX:
2x + y = -5 so
y = -2x - 5
The slope is -2. That means that the reciprocal slope is 1/2. Using that slope along with the coordinates x = -1 and y = -2, we first write the line using point-slope form and then solve it for y. Start by filling in the m, the x value and the y value:

Getting rid of the double negatives gives us:

Distributing then gives us:

And finally solving for y (I am going to express the 2 on the left as 4/2 when I move it by subtraction in order to add those fractions):

And the final equation in slope-intercept form is:

Answer:
1 inch : 4 feet
Step-by-step explanation:
Size of the Mural is 42 feet long and 16 feet.
The original painting is 10½ inches long and 4 inches wide.
On the length
Length of Painting: Length of Mural
10½ inches: 42 feet
1 inch : 42/10½ feet
1 inch : 4 feet
On the Width
Width of Painting: Width of Mural
4 inch: 16 feet
1 inch : 16/4 feet
1 inch : 4 feet
The Scale of the Original Painting to the Mural is therefore:
1 inch : 4 feet
Answer:
32.1 pounds
Step-by-step explanation:
Given data
Percentage of body fat= 19.8%
Weight= 162pounds
Let us find 19.8% of the persons weight
=19.8/100*162
=0.198*162
=32.076
Therefore, 32.1 pounds of the weight is fat
When you solve a proportion, your first step should be to cross-multiply.

=

When you cross-multiply, you should get this equation:
(2x)(3) = (x + 3)(5)
Now, solve it using algebra.
(2x)(3) = (x + 3)(5) Multiply
6x = 5x + 15 Subtract 5x from both sides
x = 15
The value of
x is 15.
Answer:
Hi there!
Your answer is;
-2= x
Step-by-step explanation:
12= -5x +2
-2
10= -5x
/-5
-2 = x
