What is the correct value of x?
Answer:
x= -5
Step-by-step explanation:
First get X alone by dividing both sides by -4.2
-4.2x=21
-4.2. -4.2
then you're left with X = -5
To verify your answers, multiply -5 by -4.2

Which table represents a nonlinear function?
Solve for x: one over four (4x + 15) = 24
Answer:
x = 81/4
Step-by-step explanation:
multiply both sides by 4
4x + 15 = 96
subtract 15 from both sides
4x = 81
divide both sides by 4
x= 81/4
i hope that's right
Answer:
81/4

The reason is because if you look down the y axis from the origin you can see the location where the line crosses over the y axis in this case it was at (0,-5)
Solve the system of equations - x - y = 6 and 5x -7y=66 by combining the equations
Answer: Let's solve for x.
−x−y=6
Step 1: Add y to both sides.
−x−y+y=6+y
−x=y+6
Step 2: Divide both sides by -1.
−x
−1
=
y+6
−1
x=−y−6
Answer:
x=−y−6
Let's solve for x.
5x−7y=66
Step 1: Add 7y to both sides.
5x−7y+7y=66+7y
5x=7y+66
Step 2: Divide both sides by 5.
5x

6 pounds of strawberries cost $13.50. What is the cost of 50 pounds of strawberries?
Answer:
$112.50
Step-by-step explanation:
13.50 / 6 = 2.25; this is how much it cost per pound
2.25 * 50 = 112.50

Answer: 6, 4.5
Step-by-step explanation:
Each week jake gets an allowance of $8 plus $3 for each chore he does at
home. His younger sister bella gets an allowance of $6 plus $2 per each chore
she does. Write an expression for how much their parents give them each week if
they do the same number of chores.
Answer:
y = 5x + 14
Step-by-step explanation:
y represents the total money their parents give them. X represents the number of chores. 5 is the sum of 3 + 2 since Jack gets $3 for each chode while Bella gets $2 for each chore. 14 is the set amount of money the receive each week since 8 + 6 is 14.
The relationship between a rubber band's length and the weight attached to it is a function. The more weight, the longer the rubber band will be. The increase of
the rubber band's length is called deflection Students in science class have measured how much a rubber band would stretch if different weights, in ounces,
were attached to it. They recorded the data collected in the experiment by constructing a graph:

4. A hot air balloon hovers 100 feet about the ground. The balloon is tethered to the ground with a
rope that is 250 feet long. At what angle of elevation, is the rope attached to the ground? Round
you answer to the nearest degree.
Answer:
[tex]\theta=24^\circ[/tex]
Step-by-step explanation:
Trigonometry and Right Triangles:
The ratios of the sides of a right triangle are called trigonometric ratios. Any angle or side length can be calculated using the appropriate trigonometric ratio.
Please refer to the image below. The balloon is 100 feet high and the rope has a length of 250 feet. The right triangle formed allows us to apply a trigonometric ratio that relates the two given side lengths: the hypotenuse and the opposite leg to angle θ.
The sine ratio is defined as:
[tex]\displaystyle \sin\theta=\frac{\text{opposite leg}}{\text{hypotenuse}}[/tex]
[tex]\displaystyle \sin\theta=\frac{100}{250}=0.4[/tex]
[tex]\displaystyle \sin\theta=0.4[/tex]
Calculating θ:
[tex]\theta=\arcsin 0.4[/tex]
[tex]\theta=23.6^\circ[/tex]
To the nearest degree:
[tex]\mathbf{\theta=24^\circ}[/tex]

The difference of the square of a number and 28 is equal to three times that number find the negative solution
Answer:
The negative solution = x = -4
Step-by-step explanation:
Let the number be = x
The square of number = x²
The difference between the square of a number and 28 = x²-28
Given that the difference of the square of a number and 28 is equal to three times that number.
Thus, the equation becomes
[tex]x^2-28=3x[/tex]
subtract 3x from both sides
[tex]x^2-28-3x=3x-3x[/tex]
[tex]x^2-3x-28=0[/tex]
[tex]\left(x+4\right)\left(x-7\right)=0[/tex]
[tex]x+4=0\quad \mathrm{or}\quad \:x-7=0[/tex]
[tex]x=-4,\:x=7[/tex]
Thus, the negative solution = x = -4
Find the length and width of the frame
Answer:
The width is - 4 the lengeth is - 7
Step-by-step explanation:
w*l = 28in²
w = ?
l = w+3
w=2
2+3 = 5
5*2 = 10
w = 3
3+3 = 6
6*3 = 18
w = 4
4+3 = 7
7*4 = 28
So,
W = 4 L = 7
Approximate the solution to this system of equations. y = –2x + 6 y = 4x – 1
Answer:
x = 1[tex]\frac{1}{6}[/tex], y = 3[tex]\frac{2}{3}[/tex]
Step-by-step explanation:
y = -2x + 6 --- Equation 1
y = 4x - 1 --- Equation 2
Since both (-2x + 6) and (4x - 1) have the same total, y, they are equal.
-2x + 6 = 4x - 1
Isolate the like terms.
6 + 1 = 4x + 2x
Evaluate like terms.
6x = 7
Find x.
x = [tex]\frac{7}{6}[/tex]
x = 1[tex]\frac{1}{6}[/tex]
Substitute x = [tex]\frac{7}{6}[/tex] into Equation 2:
y = 4x - 1
y = 4([tex]\frac{7}{6}[/tex]) - 1
= 4[tex]\frac{2}{3}[/tex] - 1
y = 3[tex]\frac{2}{3}[/tex]

Do the equations 3x + 2y =7 and y= -x + 7 define the same line . plsssss help
9514 1404 393
Answer:
no
Step-by-step explanation:
When the second equation is put in standard form like the first equation is, then you can see they are different. They do not define the same line.
3x +2y = 7
x + y = 7 . . . . . second equation in standard form

the question is on the sheet.
area of the whole figure
= (x + 1)(2x + 3)
= x(2x + 3) + 1(2x + 3)
= 2 {x}^{2} + 3x + 2x + 3
= (2x)^(2} + 5x + 3
area of the unshaded region
= x(2x)
= 2x²
area of the shaded region
= 2x² + 5x + 3 - 2x²
= (2x² - 2x² ) + 5x + 3
= 5x+ 3
THEREFORE,
THE AREA OF THE FRAME IS C. 5x + 3

Answer:
(a/b)^k=a^k/b^k
Step-by-step explanation:
Using the laws of exponents, we know that (a/b)^k=a^k/b^k.
I couldn't get it to format correctly so just know that the "/" are for the fraction signs and the "^" is for the exponent marking.
Answer:
a^k / b^k
