Answer:
y = -1/5x - 1
Step-by-step explanation:
Perpendicular lines slopes are negative reciprocals of each other.
Write the given equation in the slope-intercept form: y = mx + b
5x - y = 3
-y = -5x + 3
y = 5x - 3 multiply by -1
The slope of the given line is 5 ( the coefficient of the x-term).
The slope of the new equation will -1/5 (this is the negative reciprocal of 5).
Next find "b" using y = mx + b, the new slope -1/5 and the point (0, -1)
y = mx + b
-1 = -1/5(0) + b
-1 = 0 + b
-1 = b
Now write the equation y = -1/5x - 1

When a whole number is multiplied by 10 to the power of 4 how does the placement of the decimal point change
9514 1404 393
Answer:
The decimal point moves 4 places to the right
Step-by-step explanation:
Take a simple case using the whole number 3.
3. — whole number we're starting with
3.×10^4 = 3.×10,000 = 30,000. — multiplied by 10^4
The decimal point moves 4 places to the right.
_____
Additional comment
Multiplying be a positive power of 10 moves the decimal point a number of places equal to that power. Effectively, the number of zeros added on the right is equal to the power of 10. Above, you will notice multiplying by 10^4 added 4 zeros to the right of the number.
A store has 2 employees that earn 173 dollars altogether. If they all earn the same amount, how much does each employee earn?

Step-by-step explanation:
Each of the two employees earn $86.50
y=−4x−3 y=−2x+1 ( Ignore this part i had to write it)
Answer:
Solve equation [2] for the variable y
[2] y = -2x + 1
// Plug this in for variable y in equation [1]
[1] (-2x+1) + 4x = -3
[1] 2x = -4
// Solve equation [1] for the variable x
[1] 2x = - 4
[1] x = - 2
// By now we know this much :
y = -2x+1
x = -2
// Use the x value to solve for y
y = -2(-2)+1 = 5
Solution :
{y,x} = {5,-2}

x = 68°, find the measures of angles 1, 2, and 3.
Answer:
[tex] < 1 = 112 \degree\\ < 2 = 68 \degree \: \\ < 3 = 112 \degree[/tex]
Step-by-step explanation:
As the vertically opposite angles are equal,
[tex]x = < 2 \\ x = 68 \\ so \\ < 2 = 68 \degree[/tex]
As the angles in a straight line is added up to 180°
[tex] < 1 + < 2 = 180 \\ < 1 + 68 = 180 \\ < 1 = 112 \degree[/tex]
Also,
[tex] < 2 + < 3 = 180 \\ 68 + < 3 = 180 \\ < 3 = 112 \degree[/tex]
Hope this helps you.

I need help solving the problem
Answer:
a) 16-x=x+4
add x to both sides
16=2x+4
subtract 4 from both sides
12=2x
divide both sides by 2
x=6
b) (8-x)-5=2
add 5 to both sides
8-x=7
add x to both sides
8=7+x
subtract 7 from both sides
x=1
c) 4+x=x+4
subtract 4 from both sides
x=x
x belongs to all real numbers.

Use the given conditions to write an equation for the line in slope-intercept form.
Passing through (5, 3) and (4, 6)
Answer:
y=-3x+18
Step-by-step explanation:
since they gave us two points, we can find the slope: (y_2 - y_1)/(x_2 - x_1) -> (6-3)/(4-5)=(3)/(-1)=-3 so the slope is -3. now we have [tex]y=-3x+b[/tex]. next we have to find b. to do this just plug a point into the equation: 3= -3*5 +b, 3=-15+b, b=18. so now we have y=-3x+18

Answer:
x - (5 -sqrt149 ) / 4 and x- (sqrt149+5)/4 = = x - -4.3016389 and x - 4.3016389
Step-by-step explanation:
1/2 x-5(x-1/3)=5/4 x+3 = ( 1/2x^2-5x -1/6x -5/3) = (5/4x+3) = ( 1/2x^2-6 5/6) = (5/4x+3) convert 5/4 to 12ths = *3 = 15/12 and 5/6 * 2 = 10/12 = ( 1/2x^2-6 10/12) = (15/12x+3) = 1/2 x^2 - 15/12x -6 10/12 - 3 = 0 = 1/2 x^2 - 15/12x -3 10/12 = 0 then multiply by 2 to make 1/2 whole 1/2 x^2 (2)- 15/12x (2) -3 10/12 (2) = 0 = x^2 - 30 /12x -6 20/12 (2) = 0 simplify irregular fraction x^2 - 2 2/4x -7 3/4 = 0 then do the abc quadratic formula = x - (5 -sqrt149 ) / 4 and x- (sqrt149+5)/4 = x- -17.2065556/4 = x - -4.3016389 and 17.2065556/4 =x - 4.3016389

Answer:
Ф = 19.80 °
Step-by-step explanation:
by using pythagoras theorem
h² = p² + b²
13² = 5² + b ²
b = √194
b = 13.93
now
tanФ = p/b
Ф = tan¬1( 5 / 13.93)
Ф = 19.80 °
