Hey! The correct answer is 55.
Answer:
Step-by-step explanation:
5x + 15 + 2x = 24 + 4x
7x + 15 = 24 + 4x
7x - 4x = 24 - 15
3x = 9
x = 9/3
x = 3 <====
Answer:
The integer -37 represents the direction and the distance covered by Jose from Gainesville to Ocala.
Step-by-step explanation:
The direction is represented by the sign that accompanies the distance, since Jose is returning from Gainesville, then the direction must represented by a minus sign (-), since he is travelling southwards. The distance is the magnitude of the length covered by Jose during his return. Hence, distance is represented by the natural number 37.
Finally, the integer -37 represents the direction and the distance covered by Jose from Gainesville to Ocala.
This is a geometric sequence of the form:
a(n)=(x+3)(-2x)^(n-1) because each term is -2x times the previous term...so
a(8)=(x+3)(-128x^7)
a(8)=-128x^8-384x^7
Answer:
Step-by-step explanation:
The quadratic formula helps us find the roots of a quadratic equation. The equation is:
where
The discriminant is just the part under the square root. This helps tell us if there are two, one, or zero real solutions.
The discriminant is:
We are given the quadratic:
Therefore, a is 9, b is -8, and c is -2.
Solve the exponent.
Multiply 4, 9, and -2.
The discriminant is 136. Since it is a non-zero, positive number, this quadratic has 2 real solutions/zeroes/roots.
