Answer:
Where m is the slope and b is the y-intercept. So in this case m=5 and b=-4, or in other words the slope is 5 and the y-intercept is (0,-4) (since x=0 for all y-intercepts).
Answer:
The slope is 5 and the y-intercept is -4.
Step-by-step explanation:
The slope intercept formula is y=mx+b. 5 is the m and -4 is the b. Hope this helps!

Olly took a taxi 12 miles and paid $8.40. The cab driver charges $0.45 per mile after a flat fee. How much would it cost if Olly needed to take the taxi for 25 miles?
Answer:
$14.25
Step-by-step explanation:
12 x 0.45 = 5.4
8.40-5.40=3
3 is the flat fee
3+(0.45 x 25) = 14.25
Answer:
$14.25
Step-by-step explanation:
8.40 = .45(12) + b
8.40 = 5.4 + b
b = 3
b = .45(25) + 3
b = 11.25 + 3
b = 14.25

Raise these monomials to their given powers.
(5x2y3) to the power of 2 (x2 means x squared, y3 means y cubed)
(-4ax3) to the power of 3 (ax3 means ax cubed)
(-2m3n2t) to the power of 4 (2m3 means 2m cubed, n2 means n cubed)
(-a2bc3) to the power of 5 (-a2 means -a squared, c3 means c cubed)
Answer:
For the last one,it is -a^10b^5c^15
Step-by-step explanation:
When you raise monomials to a power, you multiply each thing inside the parenthases by the power you are raising it to. (-a^2bc^3)^5=(-a^5x3)(b^1x5)(c^3x5)=-a^10b^5c^15

The answer is 57.7 x.
Step-by-step explanation:
given : 2x+8=5x-13; prove x=7
Answer:
True
Step-by-step explanation:
The left side 22 is equal to the right side 22 , which means that the given statement is always true.
Step-by-step explanation:
If we want to prove that x is equal to seven, we should first solve the equation for x so:
2x + 8 = 5x - 13
We should first add 13 on both sides and subtract 2x from both sides:
2x + 8 + 13 - 2x = 5x - 13 + 13 - 2x
21 = 3x
We can then divide both sides by 3 to get:
x = 7

Factor the following polynomial
a^4 b^3-a^3b^4 +a^2b^5
Answer:
a^2 b^3 (b^2 - a b + a^2)
Step-by-step explanation:
Factor the following:
a^2 b^5 - a^3 b^4 + a^4 b^3
Hint: | Factor common terms out of a^2 b^5 - a^3 b^4 + a^4 b^3.
Factor a^2 b^3 out of a^2 b^5 - a^3 b^4 + a^4 b^3:
Answer: a^2 b^3 (b^2 - a b + a^2)

125x^3+343y^3
Answer:
(5x + 7y)(25x² - 35xy + 49y²)
Step-by-step explanation:
125x³ + 343y³ ← is a sum of cubes and factors in general as
a³ + b³ = (a + b)(a² - ab + b³) , thus
125x³ + 243y³
= (5x)³ + (7y)³
= (5x + 7y)((5x)² - 5x(7y) + (7y)² )
= (5x + 7y)(25x² - 35xy + 49y²)

4.5(8-x)+36=102-2.5(3x+24)
Answer: x= -10
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
4.5(8−x)+36=102−2.5(3x+24)
(4.5)(8)+(4.5)(−x)+36=102+(−2.5)(3x)+(−2.5)(24)(Distribute)
36+−4.5x+36=102+−7.5x+−60
(−4.5x)+(36+36)=(−7.5x)+(102+−60)(Combine Like Terms)
−4.5x+72=−7.5x+42
−4.5x+72=−7.5x+42
Step 2: Add 7.5x to both sides.
−4.5x+72+7.5x=−7.5x+42+7.5x
3x+72=42
Step 3: Subtract 72 from both sides.
3x+72−72=42−72
3x=−30

Lewis is saving for a down payment of $8,750 on a house. The initial amount of money he has saved is $250, and the amount of money he plans on saving every month is $340. To model the situation, he created this equation, where x represents the number of months and y represents the total amount of savings: y = 250 + 340x. Determine the missing steps and justifications.
Answer:
Steps have justified that;
y = $250 + $340x
Step-by-step explanation:
We are told Lewis is saving for a down payment of $8,750 on a house.
Now, the initial amount of money he has saved is $250, while the amount of money he plans on saving every month is $340.
Thus, if x represents the number of months and y represents the total amount of savings. It means that;
For x number of months, he saves; $340x
Now, the initial amount he saved is $250.
This means that the total amount he would have saved after x number of months is;
Total amount saved = Initial savings + Amount saved monthly after x number of months.
Now, total amount saved is denoted as y as given in the question, then we have;
y = $250 + $340x
Answer:
subtraction
y-250=340x
division
y-340=250x
