Honestly just use desmos or mathyway
Answer:
c
Step-by-step explanation:
0.52 x 0.24 means "about a half times 0.24". Given the multiple choice answers, the correct answer is therefore 0.1224 (since this is the only one smaller than 0.24).
Proof:
0.50 × 0.24 = 0.12
0.01 × 0.24 = 0.0024
And therefore 0.51 × 0.24 = 0.12 + 0.0024 = 0.1224
Answer:
The equation is
2.7x - 5.4
Step-by-step explanation:
Gas is priced at $2.70 per gallon. My gas tank has 2 gallons currently in the tank. Write an equation to how much
the money I will spend to fill up my tank.
Let the total gallons that would fill your tank = x
The tank currently has 2 gallons
A gallon =>$2.70
Therefore, our equation is
=(x - 2) × 2.70
= 2.7x - 5.4
Such an equation would be y + 8x = - 25 (standard form) OR y = -8x - 25 (y-intercept form)
Deriving The Answer:
By using the point-slope form of the equation of a line, by knowing the gradient of that line and a point on that line, the equation of this line can be derived.
Now, the point-slope form exists as y - y₁ = m ( x - x₁)
since slope = -8 and the point on the line = (-4 , 7)
Then m = - 8
x₁ = - 4
y₁ = 7
⇒ y - 7 = -8 ( x - (-4))
⇒ y - 7 = -8x - 32
⇒ y + 8x = - 25
