Answer:
The equation is y = 6x - 5
Step-by-step explanation:
The equation is y = mx + b
7 = 2m + b
-5 = b (since x = 0)
Plug back in the first.
7 = 2m - 5
2m = 12
m = 6
Find the length of the shorter leg of a right triangle if the longer leg is 15 feet more than the shorter leg and the hypotenuse is 15 feet less than twice the shorter leg
Answer:
45
Step-by-step explanation:
Let the length of the shorter leg be represented as x.
Let the length of the longer let let be represented as x+15
While the length of the hypotenuse be 2x-15.
From the knowledge of phythagoras theorem:
x^2+(x+15)^2 = (2x-15)^2
x^2+x^2+15x+15x+225 = 4x^2-30x-30x+225
2x^2+30x+225 = 4x^2-60x+225
2x^2-4x^2+30x+60x+225-225=0
-2x^2+90x+0= 0
2x^2-90x = 0
Divide through by 2
x^2-45x=0
x(x-45)=0
x = 0 or x-45=0
Considering x-45=0
x-45=0
x = 45
If x is for the shorter leg,
The length for the longer leg is: x+15
= 45+15
= 60
For the hypotenuse = 2x-15
= 2×45-15
= 90-15
= 75

Find the product of 2r^2(6r^3+14r^2-30r+14)
Answer:
12 [tex]r^{5}[/tex] + 28 [tex]r^{4}[/tex] - 60 r³ + 28 r²
Step-by-step explanation:
a(b ± c) = ab ± ac (distributive property)
[tex]a^{m} * a^{n} = a^{m+n}[/tex]
2r²(6r³ + 14r² - 30r + 14) = 12 [tex]r^{5}[/tex] + 28 [tex]r^{4}[/tex] - 60 r³ + 28 r²
Answer: 2r2(6r3+14r2−30r+14)
Step-by-step explanation:
Apply the distributive property
2r2(6r3)+2r2(14r2)+2r2(−30r)+2r2⋅14
Simplify
2⋅6(r2r3)+2⋅14(r2r2)+2⋅−30(r2r)+28r2
Simplify each term
12r5+28r4−60r3+28r2

Here are two rectangles.
B
A
The length of rectangle B is 25% greater than the length of rectangle A.
3
The width of rectangle B is three fifths x the width of rectangle A.
Find the fraction of area of rectangle b over area of rectangle a
Give your answer in its simplest form.
Answer:
[tex] \frac{Area \:of\: rectangle\: A}{Area \:of\: rectangle\: B} =\frac{4}{3}[/tex]
Step-by-step explanation:
Let the length of rectangle A be x units.
So, length of rectangle B
= x + 25% of x
= x + 0.25x
= 1.25x
Let the width of rectangle A be y units
So, Width of rectangle B
[tex]= \frac{3}{5}\times x\\
=0.6x [/tex]
Area of rectangle A = xy
Area of rectangle B
= 1.25x * 0.6y
= 0.75xy
[tex] \frac{Area \:of\: rectangle\: A}{Area \:of\: rectangle\: B} =\frac{xy}{0.75xy}\\\\
\frac{Area \:of\: rectangle\: A}{Area \:of\: rectangle\: B} =\frac{1}{0.75}\\\\
\frac{Area \:of\: rectangle\: A}{Area \:of\: rectangle\: B} =\frac{100}{75}\\\\
\red{\bold{\frac{Area \:of\: rectangle\: A}{Area \:of\: rectangle\: B} =\frac{4}{3}}} \\\\[/tex]

If these numbers represent elevations in meters, which is the farthest away from sea level?
Answer:
Option (1)
Step-by-step explanation:
Minus notation of the elevations from the sea level represents the distance below the sea level and positive notation represents the elevations above the sea level.
+7 → 7 meters above the sea level
-3 → 3 meters below the sea level
[tex]+\frac{1}{2}[/tex] → 0.5 meters above the sea level
-0.8 → 0.8 meters below the sea level
+0.8 → 0.8 meters above the sea level
[tex]-\frac{1}{10}[/tex] → 0.1 meters below the sea level
-2 → 2 meters below the sea level
Therefore, +7 meters above the sea level will be the farthest point from the sea level.
Option (1) will be the answer.

Answer:
for the first one I got y=-2x-2 the second part i got y=-x-1 or -1x-y-1=0 Correct me if I am wrong
Step-by-step explanation:
Use the slope formula
-4-4 =-8
/ =-2
1 - -3=4
2. The second part use this formula y-y1=m(x-x1)
y--4=-1(x-3)
y+4=-x+3
-4 -4
y+0=-x-1
y=-x-1 or -1x-y-1=0 I am not sure

Jerry purchases a used sofa for $275. He cleans and reupholsters the sofa to make it look brand new. After all the improvements, Jerry sells the sofa for 40% more than what he originally purchased it for. What was the profit Jerry made after selling the sofa?
Answer:
$110Step-by-step explanation:
Step one:
we are told that the cost of the sofa is $275
also, he sells it for 40% more of the cost price
let us find 40% of $275
=40/100*275
=0.4*275
=110
=$110
Step two:
This means that the selling price is 275+110
=$385
profit = selling price- cost price
profit=385-275
profit=$110

A $20.00 pair of jeans is discounted 20%. What is the final price of the jeans?
Answer:
It should be 4 dollars I believe
Step-by-step explanation:
Answer:
It is given that a $20.00 pair of jeans is discounted 20%. We need to find the final price of the jeans. Therefore, the final price of the jeans is $16.00
Final price of the jeans = 20 - 20% of 20
Therefore, the final price of the jeans is $16.00.
7x - 4 + x = -1 + 13x + 7
Show work
Answer:
7x-4+x=-1+13x+7
8x-4=13x+6
add 4 to both sides
8x-4+4=13x+6+4
8x=13x+10
subtract 13x from both sides
8x-13x=13x+10-13x
-5x=10
divide both sides by -5
-5x÷-5=10÷-5
x=-2
