What is the solution of the system? Use either the substitution method or the elimination method. 4x + 2y = 104x + 2y = 10 x − y

bixtya [17]

4x+2y=10 Equation 1
x-y=13 Equation 2
Solving by substitution method.
Isolate x from equation 2.
x=y+13
Substitute value of x in equation 1
4(y+13)+2y=10
4y+52+2y=10
6y+52=10
6y=-42
y=-7
Now substitute value of y in x=y+13
x=-7+13
x=6

The gym is filled with 215 students & adults. Student tickets are $.50 and adults are $2.00. If $250.00 was collected, how m

BARSIC [14]

In order to determine the correct answer, it would be helpful to set up equations. We do as follows:

Let x = students
y = adults

x + y = 215
.50x + 2y = 250

SOlving simultaneously, we have:

x = 120 students
y = 95 adults

Hope this answers the question. Have a nice day.

The compound inequality 8.00 ≤ x < 9.50 represents all values, x, for which college students are paid hourly as teacher assis

Svet_ta [14]

the answer is C. x ≥ 8.00 and x < 9.50
proof
x ≥ 8.00 is equivalent to 8.00 ≤ x, and we have also x < 9.50
so x ≥ 8.00 and x < 9.50 or 8.00 ≤ x < 9.50

The water reaches a max height when the horizontal distance from the firefighter to the building is approximately __m. Round to

elena-s [515]

The horizontal distance from the firefighter at which the maximum height of water occurs is 10.83m

Explanation:

Given:

h(x) = -0.026x² + 0.563x + 3

where,

h(x) is the height of the water

Initial speed, u = 14m/s

angle, θ = 30°

(a)

Horizontal distance = ?

h(x) = ax² + bx + c

the vertex is found at x = -b/2a

where,

x = distance to the maximum height

As compared to the equation given:

a = -0.026

b = 0.563

Thus,

$x = \frac{-0.563}{2 X -0.026} \\\\x = \frac{0.563}{0.052}\\ \\x = 10.83m$

Therefore, horizontal distance from the firefighter at which the maximum height of water occurs is 10.83m
