in what value of b makes y= 2x + b the same as y= 2x what does that value mean
Answers
Answer:
B = 0
Step-by-step explanation:
If you have y = 2x + b and are trying to get to y = 2x
Then just remove the B itself meaning it's value would be 0 so it is as if that variable was never in the actual equation.
Basing ourselves off of the formula "y = mx + b"
B = 0 would mean that the y-intercept of the line is 0
Answer:
0
Step-by-step explanation:
if y=2x and y=2x+b is the same then b must be 0.

6m²-m²+5m-1
Step-by-step explanation:
Polynomial 1 = m³ + 3m² - 18m
Polynomial 2 = 23m - 4m²
Polynomial 3 = 5m³ - 1
(m³+3m²-18m)+(23m-4m²)+(5m³-1)
When adding polynomials, you'll add like terms.
(m³+5m³)+(3m²-4m²)+(-18m+23m)+(-1)
(6m³)+(-m²)+(5m)+(-1)
6m³-m²+5m-1
You can run at a speed of 6 mph and swim at a speed of 3 mph and are located on the shore, 4 miles east of an island that is 1 mile north of the shoreline. How far should you run west to minimize the time needed to reach the island?
Answers
The distance to run to minimize the time needed to reach the island is
3.4 miles
What is the Pythagorean theorem?Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
Let x = distance to run.
Remaining distance to the point that is closest to the island = (4 - x) miles.
The distance d to the point x from the island is
using the Pythagorean theorem:
d² = 1² +(4 - x)²
d² = 1 + 16 -8x + x²
d² = 17 - 8x + x²
d = √(x² - 8x + 17)
Total travel time.
= Times running + Time swimming.
Speed = Distance / Time
Time = Distance/Speed
Total time:
T = x/6 + d/3
T = x/6 +√(x² - 8x + 17)/3
Minimized time is when T' is zero.
T' = 0
1/6 + 1/3 x 1/{2(√(x² - 8x + 17)} x (2x - 8) = 0
1/6 + (2x - 8)/6√(x² - 8x + 17) = 0
Multiply 6 on both sides.
1 + (2x - 8)/√(x² - 8x + 17) = 0
√(x² - 8x + 17) + 2x - 8 = 0
√(x² - 8x + 17) = 8 - 2x
Square both sides.
(x² - 8x + 17) = (-(2x - 8))²
(x² - 8x + 17) = (2x - 8)²
x² - 8x + 17 = 4x² - 32x + 64
4x² - x² - 32x + 8x + 64 - 17 = 0
3x² - 24x + 47 = 0
Finding the roots of the quadratic equation.
We get,
x = 3.4 and 4.6
Thus,
The distance to run to minimize the time needed to reach the island is
3.4 miles

A softball bat and glove are on sale for $89.95. If the sale price is discounted 10% from the original price, what was the original price? Round to the nearest cent.
Answers
Answer:
$20.40
Step-by-step explanation:
20% off means that the new price of the skirt will be 80% of the original price:
$30(100% – 20%) = $30(80%)
Converting the percent to a decimal gives:
$30(0.8) = $24.00
There is an additional 15% off the sale price of $24.00, so the final price is 85% of the sale price:
$24(100% – 15%) = $24(85%)
Again converting the percent to a decimal gives:
$24(0.85) = $20.40

Scrooge invests $500. He found a bank that would pay him 4% interest, compounded monthly.
a) Type of exponential function.
b) Write a function to represent the situation.
c) If he deposits the whole $500 and does not deposit or withdraw any other amount, how much money would he have after 4 years?
Answers
The formula that can be used to determine the amount Scrooge would have in 4 years is: A(1 +r)^nm
A = Amount invested = $400
r = interest rate = 4/12 = 0,0333
n = number of years
m = number of compounding
$500(1.0333)^(12 x 4) = $586.60.

Given: D is the midpoint of AC, ED = FD, and angle EDA = angle FDC
Prove that: Triangle AED = Triangle CFD
Answers
Answer:
Step-by-step explanation:
Side-Angle-Side postulate (SAS)
There are ΔAED and ΔCFD triangles that are congruent due to the SAS congruence postulate.
What are congruent triangles?Two triangles are said to be congruent if their corresponding sides and angles are equal.
As per the given question,
D is the midpoint of AC, ED = FD, and angle EDA = angle FDC
In ΔAED and ΔCFD,
Side DE = Side DF
m∠EDA = m∠FDC
Side AE= Side FC
According to SAS, two triangles are congruent if the two sides and the included angle of one triangle are equal to the corresponding sides and the included angle of the other triangle.
Thus, both triangles are congruent.
Hence, there are ΔAED and ΔCFD triangles that are congruent due to the SAS congruence postulate.
