Find f(-5) if f(x) = 5x + 11. A) 4 B) 5 C) 6

Mathematics

Andru [333]3 years ago
4 0

Step-by-step explanation: Since f(x) = 5x + 11, we find f(-5)

by substituting a -5 in for the x in the function to get f(-5) = 5(-5) + 11.

Now just simplify the right side to get -25 + 11 or -14.

So f(-5) = -14.

Am not sure how to solve this problem (number 13)
Andrej [43]

check the picture below.


a positive slope, means an increasing slope, namely, a line that is higher from left-to-right, so the right tip of it is going upwards. A negative y-intercept,


now, if you notice the 3 green lines, the line is increasing, the right-side is higher than the left-side, and the y-intercept, namely where x = 0, or where the graph touches the y-axis, their y-intercept is on a negative value of y.


now, look at the red line, it has also a positive slope, is increasing, however, there's no way it can have negative y-intercept. If it remains increasing, it can only have a y-intercept of 3 or higher, but not lower than that. The only way it can have a negative value for the y-intercept is if it tips over, but if we do that, the slope will be decreasing.

A rational number is any number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. Since q may be equal to 1, every integer is a rational number. I dont know about the other question

a rain gutter is to be constructed of aluminum sheets 12 inches wide. after marking off a length of 4 inches from each edge, thi
sp2606 [1]

area of the opening 14.93 sq. inch.

From this statement "the area of the opening may be expressed as the function: a(θ) = 16 sin θ ⋅ (cos θ + 1).

if θ = 30°

We can substitute 30° in the expression a(θ) = 16 sin θ ⋅ (cos θ + 1) to get the area of the opening.

The area of the opening = 16 sin 30 ⋅ (cos 30 + 1)

                                       = 16x0.5 (0.866 + 1)

                                       = 8(1.866)

                                       = 14.93 sq. inch.

Find the equation in standard form of the line passing through the points (2,-3) and (4,2)
mario62 [17]
The line passes through (2,-3) and (4,2).

Calculate the slope of the line.
m = (2+3)/(4-2) = 5/2

The equation of the line is therefore
\frac{y-2}{x-4} = \frac{5}{2}

Cross multiply.
2(y-2) = 5(x-4)
2y - 4 = 5x - 20
2y = 5x - 16
Rewrite as
5x - 2y = 16

Answer: C. 5x - 2y = 16
