Answer:
The value of x is 3
Step-by-step explanation:
The stage is rectangular in shape.
The formula for area of a rectangle is:
Length × Width
Length = 24 feet
Width = 4x + 4 feet
Hence:
384 = (4x + 4) × (24)
384 = 96x + 96
Collect like terms
384 - 96 = 96x
288 = 96x
x = 288/96
x = 3
The value of x is 3
Witch expression is equivalent to 5(8+9)
Answer:
85
Step-by-step explanation:
Use distributive rule.
a(b + c) = a*b + a*c
5(8 + 9) = 5*8 + 5*9
= 40 + 45
= 85
Find a point-slope form for the line with slope 1/5 and passing through the point (-4,-9).
Answer:
y + 9 = [tex]\frac{1}{5}[/tex](x + 4)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = [tex]\frac{1}{5}[/tex] and (a, b) = (- 4, - 9) , thus
y - (- 9) = [tex]\frac{1}{5}[/tex](x - (- 4) ) , that is
y + 9 = [tex]\frac{1}{5}[/tex](x + 4)
1. A set of weights includes a 5 lb barbell and 8 pairs of weight plates. Each pair, p,
weights 10 lbs. If x pair of weight plates are added to the barbell, the total weight of the
barbell in pounds can be represented by the function
f(x) = 10x + 5. What is a reasonable range of the function in this situation?
Answer:
5 <= y <= 85
Step-by-step explanation:
Since the lowest weight possible is 5lbs (just the barbell and no weights) the lowest point of the range is 5lbs (the y intercept when x = 0)
The highest weight possible is 85lbs since, there is only 8 pairs of weight plates (8 is the input value) and the pairs each weigh 10lbs (the slope of the graph) + 5lbs from the barbell (y-intercept).
Using the function given, if you input 8 as the x value, you get
85 = 10(8) + 5
So the highest value of the range is 85lbs, therefore the range is 5 <= y <= 85.

17. Let f(x) = 2x2 + 5x + 6 and g(x) = 3x2 + 4x – 10.
a Find f(x) + g(x)
b. Find f(x) – g(x)
Step-by-step explanation:
f(x)+g(x)=(2x^2 + 5x +6) + (3x^2 +4x - 10)
Combine like terms
5x^2 + 9x -4
f(x)-g(x)=(2x^2 + 5x +6) - (3x^2 +4x - 10)
Distribute the negative
(2x^2 + 5x +6) + (-3x^2 -4x + 10)
Combine like terms
-x^2 +x +16
WRITE 0,000003 56 IN SCIENTIFIC NOTATION
Answer:
3.56X10^-6
Step-by-step explanation:
In converting numbers to scientific notation, simply move the decimal point of the number until the numerical coefficient is greater than 1 but less than 10. Be sure to take note of the following:
1. The numerical coefficient.
2. Number of times we move the decimal point. It will be the exponent with the base of 10.
3. The direction we take in moving the decimal point. If the direction is to the right, take the negative sign for the exponent. If the direction is to the left, take the positive sign for the exponent.
Here, we move the decimal point of 0.00000356 to the right 6 times. So, we have now 3.56X10^-6.

Dracula has 48 pieces of candy. He gave 1⁄3 of his candy to his friend and 25% of his candy to his cousin. How many pieces of candy does Dracula have left?
Please show your work.
Answer:
20
Step-by-step explanation:
1/3 of 48 is 16, and 25% of 48 is 12. 16 + 12 = 28.
48 - 28 = 20

Give an example of an equation for a linear relationship that has a faster rate of change than the one in the graph.
Answer:
One such equation is y = -5x.
Step-by-step explanation:
Let's figure out the equation of the graph.
We see two points (1, -1) and (0, 1).
The equation is y = -2x + 1.
So an equation with a faster rate of change is y = -5x.

11) Which of the following is zero of the polynomial x^3+x^2+x+1
1
-1
both options 1 and 2
None
Answer:
x = - 1
Step-by-step explanation:
Given
f(x) = x³ + x² + x + 1
If x = 1 is a factor then f(1) = 0
f(1) = 1³ + 1² + 1 + 1 = 4 ≠ 0 , thus x = 1 is not a zero
f(- 1) = (- 1)³ + (- 1)² + (- 1) + 1 = - 1 + 1 - 1 + 1 = 0
Thus x = - 1 is the only zero

Solve the compound interest problem. $3425 is invested at %7.5 compounded monthly for years. a. Find the overall amount. b. Find the compound interest.
Complete question :
Solve the compound interest problem. $3425 is invested at %7.5 compounded monthly for 2 years. a. Find the overall amount. b. Find the compound interest.
Answer:
$3977.425 ; $552.425
Step-by-step explanation:
Given that:
Principal (P) = $3425
Rate (r) = 7.5% = 0.075
Time(t) = 2 years
A = p(1 + r/n)^nt
r = rate
n = number of times compounded per year
t = time in years
A = final amount
A = 3425(1 + 0.075/12)^12*2
A = 3425(1 + 0.00625)^24
A = 3425(1.00625)^24
A = 3425(1.1612920)
A = $3977.4251
Hence, overall amount = $3977.425
Compound interest = $(3977.425 - 3425) = $552.425

if triangle GHI is equilateral and JHK is isosceles, what is the measure of JHK
Answer:
The measure of JHK is 25 degrees
Step-by-step explanation:
If GHI is equilateral, it means each of the angles are equal to 60 degrees
Thus;
7x - 31 = 60
7x = 60 + 31
7x = 91
x = 91/7
x = 13 degrees
The measure of JHK IS x + 12
simply insert the value of x here
Angle JHK = 13 + 12
Angle JHK is 25 degrees
Answer: 25

-x-3y- 3z= 16
-6x+3y+2z=-27
4x+6y+4z=-22
I will give brainliest to whoever shows steps!
Answer:
Step-by-step explanation:
-x-3y-3z=16
x=-3y-3z-16
-6x+3y+2z=-27
6x=3y+2z+27
x=3/6 y + 2/6 z +27/6
x=1/2y+1/3z+9/2
4x+6y+4z=-22
4x=-6y-4z-22
x= -6/4y -4/4 z -22/4
x=-3/2y -z-11/2
Answer:
(x, y, z) = (2,-3,-3)
Step-by-step explanation: 4x+6y+4z = -22 Divide both sides by = 2x + 3y+2z= -11
To solve the system , rewrite it as two systems each consisting of two equations.
1) {-x-3y-3z = 16} {-6x+3y+2z = -27}
2) {-x-3y-3z=16} {2x+3y+2z=-11}
Solve the system of equations
1) -7x-z=-11
2)x-z=5
Write as a system of equations
{-7z-z=-11} {x-z=5}
Solve the system of equations
z = -3
x= 2
Substitute the given value of z, x into the equation : -x-3y-3z = 16
-2-3y-3x(-3)= 16
Solve for Y
y= -3
