Answer:
y = 5x + 9
Step-by-step explanation:
Assuming you require the equation of the line.
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 5, thus
y = 5x + c ← is the partial equation
To find c substitute (- 1, 4) into the partial equation
4 = - 5 + c ⇒ c = 4 + 5 = 9
y = 5x + 9 ← equation of line
3(2x - 3) + 2x = 3x + 11

What are mathematical operations?An operation is a mathematical function that transforms zero or more discrete input values into discrete output values. The complexity of the operation depends on how many operands there are. The rules that specify the order in which specific operations should be carried out in order to solve an expression are referred to as the order of operations. Parentheses, exponents, multiplication, division (from left to right), addition, and subtraction are the order of operations. (Left to Right) PEMDAS (from left to right).So, −112−(+312)−(−58):

Angelica needs 1.25 pounds of beef to make 4 person tacos. How many pounds of beef will she need to feed 10 people?
Answer:
3.125 pounds of beef
Step-by-step explanation:
Set up a proportion where x is the number of pounds of beef needed to feed 10 people:
[tex]\frac{1.25}{4}[/tex] = [tex]\frac{x}{10}[/tex]
Cross multiply and solve for x:
12.5 = 4x
3.125 = x

If a polynomial has a root of −2, what FACTOR will divide evenly into the polynomial?
Given:
A polynomial has a root of −2.
To find:
The factor that will divide evenly into the polynomial.
Solution:
We know that, if c is a root of a polynomial P(x), then (x-c) is a factor of polynomial P(x).
we have,
-2 is a root of polynomial.
⇒ (x-(-2)) is a factor of polynomial.
⇒ (x+2) is a factor of polynomial.
⇒ (x+2) will divide the polynomial completely.
Therefore, the factor (x+2) will divide evenly into the polynomial.
The factors of a polynomial divide the polynomial evenly, without remainder
The factor of the polynomial is x + 2
The root of the polynomial is given as:
[tex]\mathbf{Root = -2}[/tex]
Assume the polynomial is a function of x.
i.e. the variable of the polynomial is x
Then the root can be represented as:
[tex]\mathbf{x= -2}[/tex]
Add 2 to both sides
[tex]\mathbf{x + 2= -2 +2}[/tex]
So, we have:
[tex]\mathbf{x + 2= 0}[/tex]
Hence, the factor of the polynomial is x + 2

Answer:
Exponents
By Vicki Young
I open up my textbook when I first get out of bed,
Start studying those rules, just like my teacher said!
Recognizing bases, exponents, too.
Exponents must be positive, negatives won't do.
I've got to work these problems, I've got to find a way.
Oh, I feel frantic today!
I start to see a pattern to how these things are done.
I raise to zero power and the answer's always one.
The base just can't be zero - I must remember that.
Just three more rules to learn now and then I can relax.
I'll put it all together, I'll know it pretty soon.
Oh, I feel better at noon!
To multiply same bases, exponents I combine.
Dividing's just the opposite, but then I must decide
To subtract the smaller power, the base correctly place.
The power rule says multiply, parentheses erase.
I know I've got these rules now, I know I've got them right.
Oh, I feel lucky tonight!

Two radar stations reconnoiter a plane at the same time. The angles
of elevation to the plane are 20° and 59º. How far apart are the two
radar stations if the plane is at an altitude of 30 km?
km (round to two decimal places)
20
59
30 km
Enter the answer
Answer:
The distance apart of the two planes is either 100.45 km or 64.40 km
Step-by-step explanation:
The given parameters are;
The angle of elevation of the plane from the two radar stations are; 20° and 59°
The altitude of the plane = 30 km
The horizontal distance from each of the radar stations from the plane is given as follows;
[tex]tan(\theta) = \dfrac{Altitude \ of \ the \ plane}{The \ horizontal \ distance \ of \ radar \ station \ from \ the \ plane}[/tex]
Therefore, we have;
[tex]The \ horizontal \ distance \ of \ radar \ station \ from \ the \ plane = \dfrac{Altitude \ of \ the \ plane}{tan(\theta)}[/tex]For each of the given radar stations, and their elevations, we have;
[tex]The \ horizontal \ distance \ of \ the \ 1st \ radar \ station \ from \ the \ plane = \dfrac{30 \ km}{tan(20^{\circ})}[/tex]
[tex]The \ horizontal \ distance \ of \ the \ 2nd \ radar \ station \ from \ the \ plane = \dfrac{30 \ km}{tan(59^{\circ})}[/tex]
The distance between the two radar stations, d = The sum of their horizontal distances from the plane
Therefore;
[tex]d = \dfrac{30 \ km}{tan(20^{\circ})} + \dfrac{30 \ km}{tan(59^{\circ})} \approx 100.45 \ km[/tex]
However, when the radar stations are on the same side, we have;
The distance between the two radar stations, dₓ = The difference of their horizontal distances from the plane
[tex]d_x = \dfrac{30 \ km}{tan(20^{\circ})} - \dfrac{30 \ km}{tan(59^{\circ})} \approx 64.40 \ km[/tex]
The distance apart of the two planes is either 100.45 km or 64.40 km
What is the slope of the line which contains the ordered pairs (2, 1) and (-3, 5)?
a. -5/4
b. -4
c. -1/4
d. -4/5
Answer:
d. -4/5
Step-by-step explanation:
When using the equation m = y2 - y1 / x2 - x1, we get m = 5-1 / -3-2.
Simplified: m = 4/-5.
The negative can be placed on the numerator or denominator, it doesn't make a difference.
