Step-by-step explanation:
let the unknown be x
24 - x^2 = 5x
-x^2 - 5x + 24 = 0
(x - 3)(x + 8) =0
x = 3 (or) x = -8
if u wanna check
if you wanna check
24 - (-8)^2 =5(-8)
24 - 64 = -40
-40 = -40
since you ask for negative solution
x= -8 is a NUMBER
the solution is 5times of a NUMBER = -8 × 5 = -40
hope I got it right^^,good luck!

Dustin needed 0.80 meter of fabric to make a pillow. The fabric cost $1.50 per meter. How much did Dustin pay for 0.80 meter of the fabric?
Given parameters:
Length of fabric needed to make a pillow = 0.8m
Cost of fabric per meter = $1.5
Unknown:
Cost of the 0.8m fabric = ?
Solution:
The cost of the fabric = cost per meter x length of fabric
Input the parameters and solve;
Cost of the fabric = 0. 8 x 1.5 = $1.2
Dustin will have to $1.2 for the fabric

what value of x makes the equation true 9.68x + 21.6 - 6.23x=2.3x+17
9.68x + 21.6 - 6.23x = 2.3x + 17
Combine like terms on the left side:
3.45x + 21.6 = 2.3x + 17
Subtract 2.3x from both sides:
1.15x + 21.6 = 17
Subtract 21.6 from both sides:
1.15x = -4.6
Divide both sides by 1.15:
X = -4

A squirrel climbs up a tree. She starts at 0.5 feet up the tree, then climbs at a steady pace for 7.5 seconds. She ends 4 feet up the tree. How many feet did she climb per second? A. 7.5 + 1 2 x = 4 B. 1 2 + 4 x = 7.5 C. 4 + 1 2 x = 7.5 D. 7.5 x + 1 2 = 4
Given :
A squirrel climbs up a tree. She starts at 0.5 feet up the tree, then climbs at a steady pace for 7.5 seconds.
She ends 4 feet up the tree.
Solution :
Now, distance covered is :
d = 4 - 0.5 = 3.5 feet.
Time taken, t = 7.5 seconds.
Distance climbed per second is :
[tex]D =\dfrac{d}{t}\\\\D=\dfrac{3.5}{7.5}\\\\D = 0.467\ feet/s[/tex]
Therefore, distance climber per second is 0.467 feet.
Hence, this is the required solution.

A cell phone company charges $4 per GB beyond 20 GB. The monthly plan is $59.99, and the bill for January is $75.99. How many GB were used in that month?
Answer:
24 GB
Step-by-step explanation:
Subtract the amount of money that was from the monthly plan:
75.99 - 59.99
= 16
Divide this by 4 to see how many extra GB were used:
16/4
= 4
This means that 4 GB were used beyond 20 GB.
This means 24 GB were used in total
Answer:
24 GB

1. If sin y = sin 35, y≠35, what is the value of y? 2. If cos y = cos z = - cos 35, y≠z≠35, what are the values of y and z? 3. If sin y = sin x and x<90, y≠x, what is the value of y in terms of x? 4. If sin y = sin z = -sin x and x<90, y≠z≠x, what are the values of y and z in terms of x? 5. If cos y = cos x and x<90, y≠x, what are the value of y and z in terms of x? 6. If cos y = cos z = - cos x and x<90, y≠z≠x, what are the values of y and z in terms of x?
Answer:
1. y = 145
2. y = 145 and z = 215
3. y = 180 - x
4. y = 180 + x and z = 360 - x
5. y = 360 - x
6. y = 180 - x and z = 180 + x
Step-by-step explanation:
1. siny = sin35
Since sin35 is positive, siny is in the second quadrant.
So siny = sin(180 - 35) = sin35
siny = sin145 = sin35
Since siny = sin145, y = 145
2. cosy = cosz = -cos35
since -cos35 is negative in the second and third quadrant,
cosy = cos(180 - 35) = -cos35 and cosz = cos(180 + 35) = -cos35
cosy = cos145 = -cos35 and cosz = cos215 = -cos35
Since cosy = cos145 and cosz = cos215,
y = 145 and z = 215
3. If siny = sinx and x < 90,
since x < 90, sinx is in the first quadrant and siny is in the second quadrant since it is positive
siny = sin(180 - x) = sinx
Since siny = sin(180 - x)
y = 180 - x
4. siny = sinz = -sinx and x< 90
since -sinx is negative and sine is negative in the third and fourth quadrant respectively, siny and sinz are in the third and fourth quadrant,
siny = sin(180 + x) = -siny and sinz = sin(360 - x) = -sinx
Since siny = sin(180 + x) and sinz = sin(360 - x)
y = 180 + x and z = 360 - x
5. cosy = cosx and x < 90
Since cosx is positive in the first and fourth quadrant, and x is in the first quadrant,
cosy = cos(360 - x) = cosx
cosy = cos(360 - x)
y = 360 - x
6. cosy = cosz = -cosx and x< 90
since -cosx is negative in the second and third quadrant,
cosy = cos(180 - x) = -cosx and cosz = cos(180 + x) = -cosx
cosy = cos(180 - x) and cosz = cos(180 + x)
y = 180 - x and z = 180 + x
What is the equation of a line in point slope form that oases trough (-2,-6) and has a slope of 1/3
Answer:
y + 6 = [tex]\frac{1}{3}[/tex](x + 2)
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}{3}[/tex] and (a, b) = (- 2, - 6 ) , thus
y - (- 6) = [tex]\frac{1}{3}[/tex](x - (- 2) ) , that is
y + 6 = [tex]\frac{1}{3}[/tex](x + 2)

Explain your reasoning. for the answer to 2.5 x 4
Answer:
10
Step-by-step explanation:
2.5 plus 2.5 is 5 and 5 times 2 is 10, so 2.5 times 4 is 10.
The value of the given expression is 10.
We are given that;
The expression= 2.5 x 4
Now,
To multiply 2.5 by 4, we can use the distributive property of multiplication.
This means that we can split 2.5 into 2 and 0.5, and then multiply each part by 4 separately.
2.5 x 4 = (2 + 0.5) x 4
= (2 x 4) + (0.5 x 4)
= 8 + 2
= 10
So, 2.5 x 4 = 10.
Therefore, by algebra the answer will be 10.

Write a quadratic function in standard form with zeros 7 and 2
Answer:
y = x² - 9x + 14
Step-by-step explanation:
Given the zeros x = 7 and x = 2, then the corresponding factors are
(x - 7) and (x - 2)
The function is then the product of its factors, that is
y = (x - 7)(x - 2) ← expand using FOIL
= x² - 9x + 14
The quadratic function with zeros 7 and 2 in standard form is
f(x) = x² - 9x + 14
If a quadratic function has zeros of a and b, then the quadratic function can be formed as:
f(x) = (x - a)(x - b)
For a function with zeros 7 and 2:
a = 7, b = 2
Substitute a = 7 and b = 2 into the quadratic function f(x) = (x - a)(x - b)
f(x) = (x - 7)(x - 2)
Expand the expression
f(x) = x² - 2x - 7x + 14
f(x) = x² - 9x + 14
The quadratic function with zeros 7 and 2 in standard form is f(x) = x² - 9x + 14

X=2,,X=-2
Answer:
x = ± 2
Step-by-step explanation:
Given
x² - 3x - 1 = - 3x + 3 ( subtract - 3x + 3 from both sides )
x² - 4 = 0 ( add 4 to both sides )
x² = 4 ( take the square root of both sides )
x = ± [tex]\sqrt{4}[/tex] = ± 2
