Answer:
what function
we cant see a problem
Step-by-step explanation:
Evaluate and solve for the variable and show your work please.
x – 7 = 4 + 10
12 – c = 8
–4 – 10 = 4y + 3y
–42 + 20 = –2x + 13x
x – 7 = 4 + 10 (x=21)
x−7=4+10
x+−7=4+10
x−7=(4+10)(Combine Like Terms)
x−7=14
x−7=14
Step 2: Add 7 to both sides.
x−7+7=14+7
x=21
---------------------------------------------------
12−c=8 (c=4)
12+−c=8
−c+12=8
Step 2: Subtract 12 from both sides.
−c+12−12=8−12
−c=−4
Step 3: Divide both sides by -1.
−c
−1
=
−4
−1
c=4
----------------------------------
−4−10=4y+3y (y=−2)
−4+−10=4y+3y
(−4+−10)=(4y+3y)(Combine Like Terms)
−14=7y
−14=7y
Step 2: Flip the equation.
7y=−14
Step 3: Divide both sides by 7.
7y
7
=
−14
7
y=−2
------------------------------------
-42=20=-2=13x (x=−2
Simplifying
-42 + 20 = 2x + 13x
Combine like terms: -42 + 20 = -22
-22 = 2x + 13x
Combine like terms: 2x + 13x = 15x
-22 = 15x
Solving
-22 = 15x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-15x' to each side of the equation.
-22 + -15x = 15x + -15x
Combine like terms: 15x + -15x = 0
-22 + -15x = 0
Add '22' to each side of the equation.
-22 + 22 + -15x = 0 + 22
Combine like terms: -22 + 22 = 0
0 + -15x = 0 + 22
-15x = 0 + 22
Combine like terms: 0 + 22 = 22
-15x = 22
Divide each side by '-15'.
x = -1.466666667
Simplifying
x = -1.466666667

Where is (-2.5, -2) located on the coordinate plane?
Answer: It is located in quadrant III (3) of the coordinat plain
Step-by-step explanation:
You can use the negative numbers to find their placement. if there are no negative numbers, it’s in quadrant I (1). If there‘s a negative number for the Y-coordinate, then it’s in quadrant II (2). If there are 2 negative numbers, it’s in quadrant III (3). And if there’s a Negative number for the X-coordinate, it’s in quadrant IV (4).
Ferdinand Freight Company charges a flat rate of $200 plus $0.75 per pound to transport freight in
the metro area. This cost is represented by the function below where w is the weight of the freight
in pounds and c(w) is the cost given the weight of the freight
c(w) = 200+ 0.750
Answer:
$1325
Step-by-step explanation:
c(w) = 200 + 0.75w
c(1500) = 200 + 0.75(1500)
c(1500) = 200 + 1125
c(1500) = 1325

Larry Mitchell invested part of his advance at annual simple interest and the rest at annual simple interest. If his total yearly interest from both accounts was , find the amount invested at each rate. The amount invested at is $ nothing. The amount invested at is $ nothing.
Complete question :
Larry Mitchell invested part of his $32000 advance at 4% annual simple interest and the rest at 9% annual simple interest. If his total yearly interest from both accounts was 2430, find the amount invested at each rate. The amount invested at is $ nothing. The amount invested at is $ nothing.
Answer:
Investment at 4% = $9000
Investment at 9% = $23,000
Step-by-step explanation:
Given that :
Total investment = 32000
Let;
amount invested at 4% = a
amount invested at 9% = 32000 - a
Total interest earned = 2430
Simple interest = principal * rate * time
Investment at 4%:
(a * 0.04) + [(32000 - a) * 0.09] = 2430
0.04a + 2880 - 0.09a= 2430
-0.05a + 2880 = 2430
-0.05a = 2430 - 2880
-0.05a = - 450
a = 9000
Hence,
Investment at 4% = $9000
Investment at 9% = $32,000 - $9000 = $23,000
Select the correct answer.
Which equation represents the line that is perpendicular to y=1/5 and passes through (-4,-3)?
A. x= -4
B. x= -3
C. y= -5
D. y= -3
Answer:
The required line's equation is x=-4. Option A.
Step-by-step explanation:
This is more conceptual than a numerical problem.
We have the line y=1/5 and want to find a perpendicular line that passes through (4,-3).
The line y=1/5 is a horizontal line with slope 0. The perpendicular line would have an infinity slope and it would make it impossible to use the regular procedure to find it.
Instead, we realize that a perpendicular line to a horizontal line is a vertical line.
All vertical lines have the equation x = h, where h is the x-component of the point it passes through.
Now we only have to see the x-component of the point (-4,-3) and write our solution:
The required line's equation is x=-4. Option A.
Answer: A. x= -4

Evaluate the function f(x) = 8x - 4 at the given values of the independent variable and simplify.
f(-2) =
f(x + 7) =
f(-x) =
Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
For the f(-2):
[tex]f(-2)=8(-2)-4\\f(-2)=-16-4\\f(-2)=-20[/tex]
For the f(x+7):
[tex]f(x+7)=8(x+7)-4\\f(x+7)=8x+56-4\\f(x+7)=8x+52[/tex]
For the f(-x):
[tex]f(-x)=8(-x)-4\\f(-x)=-8x-4[/tex]
That's all
The function f(x) = 8x - 4, At x = -2 is -20, At x = (x+7) is 8x + 52 and at x = -x is -8x -4.
What is a function ?A function can be though of as an output for given input.
According o the given question we have to evaluate the function f(x) = 8x - 4 at different values of the independent variable.
For f(-2) we'll replace x with -2 in this function
f(-2) = 8(-2) - 4.
f(-2) = -16 - 4.
f(-2) = - 20.
For f(x+7) we'll replace x with (x+7).
f(x+7) = 8(x+7) - 4.
f(x+7) = 8x + 56 - 4.
f(x+7) = 8x + 52.
For f(-x) we'll replace x with -x in this given equation.
f(-x) = 8(-x) - 4.
f(-x) = -8x - 4.
