Answer:
x = -2
Step-by-step explanation:
Given f(x) = 3x – 1
f(x) = -7
3x-1 = -7
3x = -7+1
3x = -6
x = -2
Answer:
x = -22
Step-by-step explanation:
given:
[tex]f(x) = 3x - 1[/tex]
solve for x, when:
[tex]f(x) = -7[/tex]
replace x with -7
~~~~~~~~~~~~
➡️ [tex] x = 3(-7) - 1 [/tex]
➡️ [tex] x = -21 - 1 [/tex]
➡️ [tex]x = -22 [/tex]

Find the midpoint of (4,5) & (2,2)
Answer:
&
Step-by-step explanation:
Answer:
[tex]\boxed {\boxed {\sf (3, \frac{7}{2}) \ or \ (3, 3.5)}}[/tex]
Step-by-step explanation:
The midpoint is the middle point of a line segment that bisects (splits into 2 equal parts) the line segment. When we calculate the midpoint, we basically find the average of the x-coordinate, then the average of the y-coordinates. The formula is:
[tex](\frac{x_1+x_2}{2} , \frac{y_1+y_2}{2})[/tex]
In this formula, (x₁, y₁) and (x₂, y₂) are the endpoints of the segment.
We are given the points (4,5) and (2,2). Match the value and the corresponding variable.
x₁= 4 y₁= 5 x₂= 2 y₂=2Substitute these values into the formula.
[tex](\frac{4+2}{2} , \frac{5+2}{2})[/tex]
Solve the numerators.
X-coordinate: 4+2= 6 Y-coordinate: 5+2=7[tex](\frac{6}{2}, \frac{7}{2})[/tex]
Divide.
[tex](3, \frac{7}{2}) \ or \ (3, 3.5)[/tex]
The midpoint of the line segment is (3, 7/2) or (3, 3.5).
In 2015, the city of Miami had a population of 441,000 people and an area of 36 square miles. What was the population density of Miami, in people per square mile, in 2015? 10,750 12,250 14,250 16,750
Answer:
12,250
by dividing the 441000 by 36, I got the answer.
The population density of Miami, in people per square mile, in 2015 was 12,250
The given parameters are:
Population = 441,000 peopleArea = 36 square milesThe population density of a place is the ratio of the population to the unit square area.
So, we have:
[tex]Density=\frac{Population}{Area}[/tex]
Substitute known values
[tex]Density=\frac{441000}{36}[/tex]
[tex]Density=12250[/tex]
Hence, the population density of Miami, in people per square mile, in 2015 was 12,250

How can $500 be divided between four people so that each person gets $20 more than the person before.
Answer:
$95, $115, $135, $155
Step-by-step explanation:
If the first person gets x dollars:
the next person gets 20 more, so x + 20 dollars
the next person gets x + 40 dollars
and the last person gets x + 60 dollars
We add all these allocations together, and we get $500
x + (x + 20) + (x + 40) + (x + 60) = 500
Combine like terms
4x + 120 = 500
Subtract 120 on both sides
4x = 380
Divide by 4 on both sides
x = 95
So the first person gets $95.
The second person must get $115
The third must get $135
And the fourth must get $155
Checking our work:
95 + 115 + 135 + 155 = 500
Find the value of x that will make A||B.
Answer:
7
Step-by-step explanation:
By the definition of alternate interior angle:
3x-2=2x+5
3x-2x=5+2
x=7
Note:if you need to ask any question please let me know.
Answer:
x = 7
Step-by-step explanation:
since these are alternating interior angles, these two expressions will be = to each other
2x+5=3x-2
subtract the 2x from both sides
5=x-2
add the 2 to both sides

Find the slope of the line through each pair of points.(-10, -1). (-15, -7)*
Answer:
6/5
Step-by-step explanation:
To find the slope, we use the formula
m = ( y2-y1)/(x2-x1)
= ( -7 - -1)/(-15 - -10)
= (-7+1)/(-15+10)
= -6/-5

What is the inverse of the function f(x) = 2x – 10?
Answer:
The inverse f-1(x) = ( x + 10)/2.
Step-by-step explanation:
f(x) = 2x - 10
Find x in terms of f(x):
2x = f(x) + 10
x = (f(x) + 10))/ 2
Replace x by the inverse f-1(x) and f(x) by x:
f-1(x) = (x + 10)/2.

21. Describe a real-life situation that can be modeled by an absolute-value equation
with the solutions x = 5 and x = 10.
Will give Brainly
The absolute value of a number returns the positive value of the given number. A real life situation that describes the scenario is:
"the point which a boy stands if the boy is standing 2.5 meters away from the 7.5 meters point."
Given that:
[tex]x = 5\ or\ x = 10[/tex]
An example of real life situation is as follows:
Calculate the point which a boy stands if the boy is standing 2.5 meters away from the 7.5 meters point.
Represent the point at which the boy stays with x. So, the situation is represented as:
[tex]|x - 7.5| = 2.5[/tex]
Remove absolute brackets
[tex]x - 7.5 = 2.5\ or\ x - 7.5 = -2.5[/tex]
Solve for x
[tex]x = 7.5+2.5\ or\ x = 7.5-2.5[/tex]
[tex]x = 10\ or\ x = 5[/tex]
Hence, the value of x is 5 or 10
