2x - 5y = 11. (4, a). x = 4, y = a
Substituting into 2x - 5y = 11
2(4) - 5(a) = 11
8 - 5a = 11
-5a = 11 - 8
-5a = 3
a = 3/-5 = -3/5 =- 0.6
Other coordinate = -3/5 = -0.6
Answer: 12 months (1 year)
We know that Alision gains $29.26 each month. She wants to buy a stereo for $339.12
You want to divide $339.12 with $29.26 to find the total months.
339.12 / 29.26 = 11.6
CHECK:
You want to round up, since she needs the money to buy a stereo. She's allowed to have more money.
29.26 * 12 = 351.12
It will take Alision 12 months (1 year) to buy her stereo.
Answer:
the answer is A or F (both are the same answer which is 40)
Answer:
-1280
Step-by-step explanation:
Given a₁ = -10, n = 8, r =2
Required to find nᵗʰ term.
From the general formula: aₙ= a₁ (r)ⁿ⁻¹
Therefore nᵗʰ = -10(2)⁸⁻¹
= -10(2)⁷
= - 10(128)
= - 1280
we know that
The x-intercept is the value of the variable x when the value of the function is equal to zero
so
In the table we have
is a x-intercept, because
For 
the value of the function is equal to zero
is a x-intercept, because
For 
the value of the function is equal to zero
therefore
<u>the answer is</u>
the continuous function in the table has two x-intercepts
