Write the equation of a line parallel to and passes through the given line’s x-intercept. Leave answer
in slope-intercept form
Answer:
y = 1/2x - 4
Step-by-step explanation:
The x-intercept is when y = 0, so it would be:
-x + 2 * 0 = 4
-x = 4
x = -4
That means the x-intercept is (0, -4)
The parallel line would have the same slope as this one, so:
[tex]-x+2y = 4\\2y = x + 4\\y = 1/2x + 2[/tex]
The parallel line has a slope of 1/2
So now you need to find the equation of a line that has a slope of 1/2 and passes through the point (0, -4)
Put it in point slope form:
y - (-4) = 1/2(x - 0)
y + 4 = 1/2x
y = 1/2x - 4

Is 2 a solution of 4z + 12 = 4? Complete the statement.
Answer:
No im pretty sure its not a solution.
Step-by-step explanation:
See if “z” is 2 than the answer to the solution would be 20
Answer:
The solution is -2
Step-by-step explanation:
4z + 12 = 4
Subtract 12 on each side (4z + 12 - 12 = 4 - 12)
4z = -8
Divide 4 on each side (4z / 4 = -8 / 4)
z = -2

Evaluate the expression for the given value of the variable 5 x (h + 3) for h = 7
If 2/3z = 6, then z=
Answer:
z=9
Step-by-step explanation:
we are given: 2/3z=6
we need to find what z is by itself
6 is 2/3rds of what the value of z is.
to find z, we need to multiply both sides by 3/2 (the reciprocal of 2/3z, to make the coefficient of 1)
3/2*2/3z=6*3/2
z=9
hope this helps :)
z = 9
Step-by-step explanation:
2/3 . z = 6
2z/3 = 6
Multiple all terms by the same value to eliminate fraction denominator,
3 x 2z/3 = 3 x 6
2z = 18 ( 3,3 got cancelled)
Divide both sides of the equation by the same term,
2z/2 = 18/2
On Simplify,
z = 9.
*(2,2 gets cancelled and 18/2 = 9)

<DBA = 90°
Step-by-step explanation:
<DBA + <DBC = 180° [Linear pair]
=> <DBA = 180° - <DBC
=> <DBA = 180 - 90
=> <DBA = 90
Hence, both the angles <DBA = <DBC = 90°
As we know that when a perpendicular bisector bisects a straight line both the angles should be,
180° ÷ 2 = 90°
And above conditions also prove that
<DBA = <DBC = 90°
Hence, DE is a perpendicular bisector of AC

If f(x)=(x+1)(x-2)(x-3) represents a student's displacement from school in
kilometers, where x is measured in minutes, which of the following is an
accurate interpretation of the student's trip?
a) The student starts 6 km from school, walks to school and arrives at school
after 2 minutes, continues walking to the playground, turns around, walks
back to the school and arrives after 3 minutes.
b) The student starts 6 km from school, walks to school and arrives at school
after 2 minutes, waits there for 1 minute, then returns home.
c) The student starts 6 km from school, walks to school and arrives at school
after 2 minutes, turns back to their house to the playground, turns around,
walks back to the school and arrives after 3 minutes.
d) The student starts 6 km from school, walks to school and arrives 1 minute
later, sits by the school, returns home, arrives after 2 minutes, and then turns
around and arrives back at school for a second time at 3 minutes.
e) None of the above are correct

Displacement means the distance traveled on a straight line to get to a certain destination. The interpretation of the given equation is option (a):
Given that:
[tex]f(x) = (x + 1)(x - 2)(x - 3)[/tex]
First, we calculate how far the student traveled to arrive at the school.
This means that we calculate f(0).
So, we have:
[tex]f(0) = (0 + 1)(0 - 2)(0 - 3)[/tex]
[tex]f(0) = ( 1)( - 2)( - 3)[/tex]
[tex]f(0) = 6[/tex]
The student walked 6km to school
When x = 2, it means:
[tex]f(x) = (x + 1)(x - 2)(x - 3)[/tex]
[tex]f(2) = (2 + 1)(2-2)(2 -3) = 0[/tex]
This means that the student got to school after 2 minutes
When x = 3, it means
[tex]f(x) = (x + 1)(x - 2)(x - 3)[/tex]
[tex]f(3) = (3 + 1)(3-2)(3 -3) = 0[/tex]
This means that the student walked away, turned back and got to school after 3 minutes.
From the given options, option (a) fits the above description.
