Question 3
Write an equivalent expression to 13.4x - 5.9 - 7.1x + 13.5 with the fewest possible terms.
Answer:
A........................
Answer:
13.4x - 0.5
Step-by-step explanation:
13.4x - 5.9 - 7.1 + 13.5
This may seem complicated, but it is really pretty simple once you get the hang of it.
First, you would organize your terms.
13.4x - 5.9 - 7.1 + 13.5
Then you would add your like terms.
-5.9 - 7.1 + 13.5 = 0.5
So the answer to your problem would be 13.4x - 0.5

write the equation of the line thay passes through the point (2,-1) and has a slope of -3
Answer:
Y = -3x -1
Step-by-step explanation:
Y = mx + b
Y is the y intercept (x,y) always graph on y axis
M is the slope
Answer:
Step-by-step explanation:
use the point slope equation.
y-y1 = m(x-x1)
the point is (x1, y1) = (2, -1)
the slope is m = -3
y+1 = -3( x-2)
y = -3x +6-1
y = -3x +5

find the coordinates of point which divides the line segment joining the points (a+b,a-b) and (a-b,a+b) in the ratio 3:2 interally
Answer:
Coordinate of 0 = [tex]\bigg( \dfrac{5a-b}{5},\:\dfrac{5a+b}{5}\bigg)[/tex]Step-by-step explanation:
Let AOB be the line segmentPoint 'O' divides the line segment into m:n = 3:2Given:
Coordinate of a = (a+b, a-b)Coordinate of b = (a-b, a+b)Ratio = 3:2ToFind:
Coordinate of 0 (zero)Solution:
ATQ,
[tex]\dfrac{m}{n}=\dfrac{3}{2}[/tex]Coordinate of a = (x[tex]_{1}[/tex], y[tex]_{1}[/tex])Coordinate of b = (x[tex]_{2}[/tex], y[tex]_{2}[/tex])As we know that,
[tex]\implies\:\:x = \dfrac{mx_{2} + nx_{1}}{m + n}[/tex]
[tex]\implies\:\:x = \dfrac{(a-b)3 + (a+b)2}{3+2}[/tex]
[tex]\implies\:\:x = \dfrac{3a - 3b + 2a + 2b}{5}[/tex]
[tex]\implies\:\:\red{x = \dfrac{5a - b}{5}}[/tex]
Similarly,
[tex]\implies\:\:y = \dfrac{my_{2}+ny_{1}}{m+n}[/tex]
[tex]\implies\:\:y = \dfrac{(a+b)3+(a-b)2}{3+2}[/tex]
[tex]\implies\:\:y = \dfrac{3a+3b+2a-2b}{5}[/tex]
[tex]\implies\:\:\red{y = \dfrac{5a+b}{5}}[/tex]
Hence,
Coordinate of 0 is [tex]\blue{\bigg( \dfrac{5a-b}{5},\:\dfrac{5a+b}{5}\bigg)}[/tex]

Answer:
25y^2 -20iy + 4i^2
Step-by-step explanation:
Theres an acronymn called Foil (first, ouside, inside, last) for expanding an expression like that
For this expression:
= (5y - 2i) (5y - 2i)
= 25y^2 - 10iy - 10iy + 4i^2
= 25y^2 -20iy + 4i^2
This is assuming that "i" is not the imaginary number "i"

Martin is ordering DVDs online. Each DVD is priced at $8.50. The website also charges a flat fee of $5.00 for shipping and handling for any size order. If Martin decides to spend no more than $56, how many DVDs can he buy?
Answer:
56
Step-by-step explanation:
...
The solution is Option A.
The inequality equation is A ≤ 6 where A is the number of DVDs Martin can buy
What is an Inequality Equation?
Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the total number of DVDs Martin can buy be = A
Now , the equation will be
The price of 1 DVD is = $ 8.50
The price for shipping and handling = $ 5.00
Now , the total amount Martin decides to spend = not more than $ 56
So , the inequality equation will be
8.50A + 5 ≤ 56
On simplifying the equation and solving for A , we get
Subtracting 5 on both sides of the equation , we get
8.50 A ≤ 51
Divide by 8.50 on both sides of the equation , we get
A ≤ 51 / 8.5
A ≤ 6 DVDs
So , the value of A should be less than or equal to 6
Hence , the inequality equation is A ≤ 6 where A is the number of DVDs Martin can buy

Find the zeros of the function y=x^2-36
Answer:
x=6,-6
Step-by-step explanation:
Whenever f(x) equals 0, the zeros of a function are indeed the values of x, and the calculation of zeros is as follows:
Finding the zeros in function:The zeros of a function indicate that when f(x) = 0, x is the function's zero. Whenever the graph crosses over x = a, the function's zero is said to be a.⇒ y=x²-36
Using formula:
⇒ a²-b²= (a+b)(a-b)
Solving equation to find zero:
⇒ y=x²-6²
⇒ y=(x-6)(x+6)
⇒ y=x±6
Therefore, the zeros of the function are "±6".

Slove the system of equations by useing the substitution method. 2x - 3y=9 y=x-4
Answer:
x = 3
y = -1
Step-by-step explanation:
in this system, we are given that y = x - 4
this means that we can take the other equation and replace y with x - 4:
so 2x - 3y=9 turns into
2x -3 (x - 4) = 9
distribute -3 to x and -4:
2x - 3x + 12 = 9
add like terms and subtract 12 from both sides
-x = -3
divide both sides by -1 to get rid of the negative on x:
x = 3
now we have the value of x, so we can replace the x in y = x - 4 with the value we just got
so y = x- 4 turns into
y = (3) - 4
solve and you get
y = -1
“ if you know the height of a ladder is 7 feet and you lean it against a barn at an angle of 70 degrees with the ground, how far up the building will you be able to reach? “
Answer:
7.45feet
Step-by-step explanation:
The set up will give a right angled triangle
Height of the ladder is the hypotenuse = 7 feet
Angle of elevation= 70 degrees
Required
Distance up the building you will be able to reach (Length of the ladder) which is he hypotenuse
Using SOH in trigonometry identity;
Sin 70 = opposite/hypotenuse
Sin 70 = 7/hyp
hyp = 7/sin70
hyp = 7/0.9397
hyp = 7.45 feet
Hence the will be able to go 7.45feet
