please help me if you can :) i gave as many points as i could.
Answer:
6. 2
7. (-3/2)
Step-by-step explanation:
6. 4x - 2y = 8
-4x -4x
-2y = -4x + 8
y = 2x + 4
y = 2/3x + 1
reciprocal of 2/3 is -3/2
Answer:
see explanation
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
(6)
Given
4x - 2y = 8 ( subtract 4x from both sides )
- 2y = - 4x + 8 ( divide all 3 terms by - 2 )
y = 2x - 4 ← in slope- intercept form
with slope m = 2
Parallel lines have equal slopes, thus
Slope of parallel line is m = 2
----------------------------------------------------------
(7)
Given
y = [tex]\frac{2}{3}[/tex] x + 1 ← in slope- intercept form
with slope m = [tex]\frac{2}{3}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{2}{3} }[/tex] = - [tex]\frac{3}{2}[/tex]
What is the value of the function at x=−2?

GRAPH ATTACHED
Answer:
y = 2
Step-by-step explanation:
When we have graph is given also one value from x and y is given then for finding the other value, We simply see the line where x = -2 is graphed and then we will see what is the value of y there.

( -4, -1 ) and ( -9, - 6)Vivian is at a fair in Coachella Valley, California. Much of the valley lies below sea level. Vivian has brought along an altimeter to measure her elevation at different places in the valley. Vivian's first ride was on the Ferris wheel. When she sat on the wheel at its lowest point, her altimeter read -9.6 feet. When she reached the top of the wheel, her altimeter read 12.3 feet.
Answer:
21.9 feet
Step-by-step explanation:
The question is incomplete. Here is the complete question.
Vivian is at a fair in Coachella Valley, California. Much of the valley lies below sea level. Vivian has brought along an altimeter to measure her elevation at different places in the valley. Vivian’s first ride was on the Ferris wheel. When she sat on the wheel at its lowest point, her altimeter read -9.6 feet. When she reached the top of the wheel, her altimeter read 12.3 feet.
Is the change in Vivian's elevation from the bottom of the Ferris wheel to the top a positive number or a negative number? Why?
Given parameters
Altimeter of vivian at its lowest point = -9.6 feet
Altimeter of vivian at the top of the wheel = 12.3feet
Note that the sea level is at 0 feet.
change in Vivian's elevation from the bottom of the Ferris wheel to the top is expressed as:
= (12.3-0)+(0-(-9.6))
= 12.3+(0+9.6)
= 12.3+9.6
= 21.9 feet
From the gotten value, it can be seen that the change in Vivian's elevation from the bottom of the Ferris wheel to the top is a positive value.
The value is positive because vivian keeps moving to the top of the wheel (above the sea level). The values above the sea level is always positive.
Answer:Hide Sample Answer
The change in Vivian's elevation is a positive number because her elevation increased as she moved from the bottom of the Ferris wheel to the top.
Step-by-step explanation:Hide Sample Answer
The change in Vivian's elevation is a positive number because her elevation increased as she moved from the bottom of the Ferris wheel to the top.

The school cafeteria sells three different types of sandwiches: chicken, turkey,
and roast beef. Chicken sandwiches sell for $3, turkey sandwiches sell for
$3.50, and roast beef sandwiches sell for $4. The cafeteria makes 400
sandwiches in total, and, if all sandwiches are sold, the cafeteria will take in
$1375. If the cafeteria makes the same number of chicken sandwiches as it
does turkey sandwiches, how many of each type of sandwich does the school
make? (Hint: Write one equation for the number of sandwiches, one equation
for to amount of money all the sandwiches cost, and an equation that show the
number of chicken and turkey sandwiches are equal.)
No
Answer:
Number of chicken sandwiches = 150
Number of turkey sandwiches = 150
Number of roast beef sandwiches= 100
Step-by-step explanation:
We are told the school cafeteriat makes and sells 3 different types of sandwiches which are; chicken, turkey and roast beef.
Let chicken be x, turkey be y and roast beef be z.
We are told they make 400 sandwiches in total.
Thus;
x + y + z = 400
However, we are told that the cafeteria makes same number of chicken and turkey sandwiches.
Thus, x = y
Thus;
Total is now;
x + x + z = 400
2x + z = 400 - - - (eq 1)
Now,we are told that chicken, turkey and roast beef sandwiches are sold for $3, $3.5 and $4 respectively. Also that the total amount realized from sales is $1375.
Thus;
3x + 3.5y + 4z = 1375
Since x = y. Thus;
3x + 3.5x + 4z = 1375
6.5x + 4z = 1375 - - - (eq 2)
Let's make z the subject in eq 1.
Thus;
z = 400 - 2x - - - (eq 3)
Putting 400 - 2x for z in eq(2) gives us;
6.5x + 4(400 - 2x) = 1375
6.5x + 1600 - 8x = 1375
1600 - 1375 = 8x - 6.5x
225 = 1.5x
x = 225/1.5
x = 150
Putting 150 for x in eq 3 gives;
z = 400 - 2(150)
z = 400 - 300
z = 100
Since x = y. Then y = 150

The function h(x)= -x2 +6x Models the path of water in a fountain in meters. The function represents the vertical distance, H, as a function of the horizontal distance, X. What is the value of H2?
Answer:
h(2) = 8
Step-by-step explanation:
We are told that the function h(x)= -x² + 6x Models the path of water in a fountain in meters
Since the function is h(x)= -x² + 6x.
It means h(2) will be;
h(2) = -(2²) + 6(2)
h(2) = -4 + 12
h(2) = 8

Write an equation in slope-intercept form for the line that passes through (4, 7) and is perpendicular to the y-axis.
The equation in slope-intercept form for the line that passes through (4, 7) and is perpendicular to the y-axis is y=0x+7 or y=7.
What is the equation of a line?A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of the line is given by,
y =mx + c
where,
x is the coordinate of the x-axis,
y is the coordinate of the y-axis,
m is the slope of the line, and
c is the y-intercept.
As it is needed that the line must be perpendicular to the y-axis, therefore, the slope of the line will be 0 and the value of y will be 0. Also, it is given that the line passes through (4, 7). Therefore, the equation in slope-intercept form for the line is,
y = mx + c
7 = 0(4) + c
c = 7
Hence, the equation in slope-intercept form for the line that passes through (4, 7) and is perpendicular to the y-axis is y=0x+7 or y=7.

Given the function f (x) = 8x2 - 14x – 10, find f -2).
Remember from now on ;
If the value of f(x) is asked, we put what thing written in parentheses inside the function instead of x. It doesn't different what is written, we just have to replace it with x.
Got it ?
Now Let's do it .....
