Answer:
h(x)= -4x-7, when x=3
Answer= h(3)= -19
Step-by-step explanation:
Substitute 3 for x in the function and simplify:
h(x) = -4x – 7
h(3) = -4(3) – 7
= -12 – 7
= -19
The value of the function h(x) = -4x - 7 at x = 3 will be -19.
What is function ?The function is defined as a relation between a set of inputs having one output each.
We have,
h(x) = -4x - 7,
So,
When
x = 3
So,
Substituting x = 3 in the given function,
i.e.
h(x) = -4x - 7
We get,
h(3) = -4 * 3 - 7
h(3) = -12 - 7
So,
h(3) = -19
So, the given function at x = 3 is -19.
Hence, we can say that the value of the function h(x) = -4x - 7 at x = 3 will be -19.

What is the equation of the line that goes through the points (4,-1) and
(2,3)?
Answer:
y = -2x + 7
Explanation:
y = mx + b
m = slope
b = y-intercept
y = a given y coordinate
x = a corresponding x coordinate
First, we need to find the slope (m).
1) (4, -1)
2) (2/3)
m = slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] = [tex]\frac{3-(-1)}{2-4}[/tex] = [tex]\frac{4}{-2}[/tex] = -2
plug in the values to the equation y = mx + b
-1 = -2(4) + b
-1 = -8 + b
7 = b
now, we can substitute in m and b into the equation y = mx + b
y = -2x + 7

Dallas, Texas has an elevation of 200 feet above sea level. The city of Jacksonville is 300 feet less than the elevation of Dallas. Select all options that apply to Jacksonville. at sea level below sea level above sea level elevation of -100 feet elevation of 100 feet
Answer:
below sea level;
-100 feets
Step-by-step explanation:
Given that:
Dallas, Texas elevation = 200 feets
Jacksonville = 300 feets less than elevation of Dallas
Hence, elevation of Jacksonville :
Dallas elevation - 300 feets
200 feets - 300 feets = - 100 feets
Hence Elevation of Jacksonville city is - 100 feets
-100 feets, means elevation of Jacksonville city is below sea level (elevation points less than 0, are below sea level).

And the file the other person shows never work, they are bots (robots) who waste your time answering your questions and waste your brainly points. ugh it gets to annoying.
Roger and Trish can finish 11x/30 of the homework if they work together for x hours.
What is Expression?An expression is combination of variables, numbers and operators.
Let the total amount of work in the math homework is 1.
In one hour, Roger can finish 1/6 of the work, and Trish can finish 1/5 of the work. So, working together for one hour, they can finish:
(1/6) + (1/5)
= (5/30) + (6/30)
= 11/30 of the work.
If they work together for x hours, then they will finish:
x × (11/30) = 11x/30
of the work in x hours.
Therefore, Roger and Trish can finish 11x/30 of the homework if they work together for x hours.

A countrys population in 1990 was 145 million. In 1998 it was 151 million. Estimate the population in 2015 using the exponential growth formula. Round your answer to the nearest million
Answer:
The population in 2015 will be 165 million.
Step-by-step explanation:
The exponential growth formula is given by:
[tex] f(t) = a(1 + r)^{\Delta t} [/tex]
Where:
a: is the initial population
r: is the rate of increase
Δt: is the time
With the initial information we can find the rate:
[tex] 151 = 145(1 + r)^{1998-1990} [/tex]
Using logarithm:
[tex] ln(151) = ln(145) + 8[ln(1 + r)] [/tex]
[tex] ln(1 + r) = \frac{ln(151) - ln(145)}{8} [/tex]
[tex] ln(1 + r) = 5.0683 \cdot 10^{-3} [/tex]
Using exponential:
[tex] e^{ln(1 + r)} = e^{5.0683 \cdot 10^{-3}} [/tex]
[tex] r = 5.081 \cdot 10^{-3} [/tex]
Now, we can find the estimated population in 2015:
[tex] f(t) = 151(1 + 5.081 \cdot 10^{-3})^{2015-1998} [/tex]
[tex] f(t) = 165 [/tex]
Therefore, the population in 2015 will be 165 million.
