Answer:
x = - 20
Step-by-step explanation:
[tex]\frac{3}{4}[/tex] x - 5 = x ( multiply through by 4 to clear the fraction )
3x - 20 = 4x ( subtract 3x from both sides )
- 20 = x
What is an equation of the line that passes through the point (−4,5) and is perpendicular to the line 4x+y=7
Answer:
[tex]y = \frac{1}{4} x + 6[/tex]
Step-by-step explanation:
rewrite the original equation
[tex]4x + y = 7 \\ y = - 4x + 7[/tex]
perpendicular line has a negative reciprocal slope. I will use this slope and substitute the points to find our y-intercept
[tex]5 = \frac{1}{4} ( - 4) + b \\ 5 = - 1 + b \\ b = 6[/tex]

Find the equation of the linear function represented by the table y 6 9 12 15 x 1 2 3 4
Answer: y = 3x + 3
Step-by-step explanation:
We know the linear function as following:
y = mx + b
m is the slope of the equation. b represents the y-intercept.
To find m, we divide the rate of change of y by the rate of change of x. We know that the rate of change y is +3 because we add three each time in order to find the next value. The rate of change of x is +1 because we add one each time to find the next value. So m would be:
m = 3/1
m = 3
Our linear equation is now as following:
y = 3x + b
In order to find b, we should first substitute a coordinate in the equation above.
y = 3x + b
6 = 3(1) + b
Then, we multiply 3 with 1
6 = 3 + b
Finally, we substract 3 on both sides. Now we've got our b value.
b = 3
Now our equation should look like this.
y = 3x + 3
To verify if the equation, we should substitute another coordinate, and verify if each side of the equation is equal.
y = 3x + 3
15 = 3(4) + 3
15 = 12 + 3
15 = 15
So we now know that the equation is indeed correct.
Answer:
y = 3x + 3Step-by-step explanation:
As per given table we have ordered pairs:
(1, 6), (2, 9), (3, 12), (4, 15)Find the slope and y- intercept to work out the equation.
y = mx + bThe slope:
m = (9 - 6)/(2 - 1) = 3/1 = 3The y -intercept:
6 = 3*1 + b6 = 3 + bb = 3The equation is:
y = 3x + 3The graph is attached

Does anybody know this question
Answer:
13h
Step-by-step explanation:
A = LW
A = 13 cm * h cm
A = 13h cm^2
We know that two sides of the rectangle are 13cm. To find the area, we need to find h. It looks like h is 1/3 of the longer side, so 13 divided by 1/3 is 4.3. 13 times 4.3 is 55.9cm. I hope this helps!

what's the missing sequence of 37 40 123 ? 372 1116
Answer:
369
Step-by-step explanation:
37 + 3 = 40
40 × 3 = 120
120 + 3 = 123
123 × 3 = 369
and so on
The missing term of the given sequence is 369.
What is sequence?
A specific is an ordered list of elements with a specific pattern.
According to the given question
We have a sequence
37, 40, 123
The first term of the above sequence = 37
The second term of the sequence = 37 + 3 = 40
The third term of the given sequence = 40 × 3 = 120
The fourth term of the sequence = 120 + 3 = 123
The fifth term of the sequence = 123 × 3 = 369
The sixth term of the sequence = 369 + 3 = 372
Hence, the missing term of the given sequence is 369.

Answer:
x = -19 or 72
Step-by-step explanation:
The range of the given numbers is 5 to 48. In order for x to make the range be 67, the value of x must be 67 less than 48, or must be 67 greater than 5.
x is 48 -67 = -19

Forced vital capacity: the maximum amount of air you can forcibly exhale from your lungs after fully inhaling. It is about 80 percent of total capacity, or 4.8 liters, because some air remains in your lungs after you exhale
9514 1404 393
Answer:
a) 1.70 L
b) 16 breaths per minute
Step-by-step explanation:
a) The maximum value of v(t) occurs when the sine function is at its maximum value of 1. In that case, the volume is ...
1.27 +0.43×1 = 1.70 . . . liters
__
b) One full breath cycle takes a period of time that makes the argument of the sine function be 2π. The that time period is ...
1.71t = 2π
t = 2π/1.71 ≈ 3.6744 . . . seconds
Then the number of breaths per minute is ...
(60 seconds/minute)/(3.6744 seconds/breath) ≈ 16.33 breaths/minute
The person takes about 16 breaths per minute while sleeping.
