a2-14=-5a is a=2, a=-7
Step-by-step explanation:
Add 5a to both sides a[tex]x^{2}[/tex]-14+5a= -5a+5a
Simplify a[tex]x^{2}[/tex]+5a-14=0
after we solve with the quadratic formula we get -7

Dakota makes salad dressing by combining 4 1/3 fluid ounces of oil and 3 3/8 fluid ounces of vinegar in a jar. She then pours 3 1/4 fluid ounces of the dressing onto her salad. How much dressing remains in the jar?
9514 1404 393
Answer:
4 11/24 fl oz
Step-by-step explanation:
The volume of dressing Dakota made is ...
4 1/3 + 3 3/8 = (4 +3) +(1/3 +3/8) = 7 + (8/24 +9/24) = 7 17/24 . . . ounces
After using 3 1/4 ounces, the remaining amount is ...
7 17/24 - 3 1/4 = (7 -3) +(17/24 -6/24) = 4 11/24 . . . . ounces
4 11/24 fluid ounces of dressing remains in the jar.

Step-by-step explanation:
Rearrange the equation so m is the independent variable. 7m + 2 = 7n − 5 , n =
Answer:
n=m+1
Step-by-step explanation:
7m+2=7n-5
add 5 to each side
7m+7=7n or 7n=7(m+1)
divide both sides by 7
n=m+1
Answer:
We have that 7m + 2 = 7n - 5
If we want to get n, you can use operations in both sides of the equation to make n the independent variable.
First, from 7m + 2 = 7n - 5, we can sum to both sides 5
7m + 2 + 5 = 7n - 5 + 5
7m + 7 = 7n
Now, we can devide both sides by 7:
(7m+7) /7 = 7n/7
7m/7 + 7/7 = n
m + 1 = n

We have two possible solutions.what is the value of -6-(x+3)y when x=(-5) and y=2
Answer:
-2
Step-by-step explanation:
So, for this question all it is asking you to do is plug in the x and y values.
-6-(-5+3)y-6-(-5+3)2-2Answer: -2
Step-by-step explanation:
-5 + 3 = -2
-6 - -2 = -4
-4/2 = -2
A complex number of the form z = a + bi has an absolute value of 4.00. What could the values of a and b be?
a = 1.6, b = 2.3
a = 1.6, b = 2.5
a = 1.9, b = 2.1
a = 2.1, b = 3.4
Answer:
According to the question z must be equal to 4. So value of a+b=z or a+b=4
Lets try each of the options
A) a+b
1.6+2.3=3.9 which is not equal to 4
So option a is not the asnwer.
B) a+b = 1.6+2.5= 4.1 which is not equal to 4
C) a+b= 1.9+2.1= 4.00 which is equal to 4
D) a+b= 2.1+3.4= 5.5 which is not eqaul to 4
Thus, we have OPTION C AS THE CORRECT ANSWER
Answer:
It's NOT C, it's D!

Determine if the sequence is arithmetic.If it is find the common difference, the 52nd term 38,47,56,65
Answer:
497
Step-by-step explanation:
Since if we take the difference between each number i.e.
47 - 38 = 9
56 - 47 = 9
65 - 56 = 9
As the difference is same that means it is a arithmetic sequence
Now
The 52nd term is
a(n) = a +(n-1)d
a(52) = 38 + (52 - 1) (9)
a(52)= 38 + 51 (9)
= 38 + 459
= 497
(6x – 2y = 5
4x – 3y = 5
Answer:
This is not a real question rephrase
Step-by-step explanation:
Which of the following is an arithmetic sequence with common difference –5?
8, 3, –2, –7, . . .
B)
0, 5, 10, 15, . . .
C)
5, 25, 125, 625, . . .
D)
5, –25, 125, –625, . . .
Answer:
Option A i.e. 8, 3, -2, -7, ... is correct.
Step-by-step explanation:
Let us check the sequence given in option A
[tex]8, 3, -2, -7, . . .[/tex]
An arithmetic sequence has a constant difference '[tex]d[/tex]' and is defined by
[tex]a_n=a_1+\left(n-1\right)d[/tex]
determine the differences of all the adjacent terms of Arithmetic sequence
[tex]3-8=-5,\:\quad \:-2-3=-5,\:\quad \:-7-\left(-2\right)=-5[/tex]
The difference between all the adjacent terms is the same and equal to
[tex]d=-5[/tex]
Therefore, we conclude that the arithmetic sequence 8, 3, -2, -7, ... has a common difference -5.
Hence, option A i.e. 8, 3, -2, -7, ... is correct.
Answer:
8, 3, –2, –7, . . .

It takes 90 minutes to vacuum 30 vehicles. At this rate, how many minutes does it take to vacuum 7 vehicles?
Answer: 21.
Step-by-step explanation: If you do '90 x 7' you get 630. With this, you will want to divide 630 by 30. So to simplify this, '(90 x 7) ÷ 30 = 21'

Find the slope of each of the lines below:
Answer: 3/10x
Step-by-step explanation:
(-4,-2) ( 6,1 )
The points are given by the graph and can be used to find the slope
using the slope formula
y2-y1 over
x2-x1
-2-1
-4-6 = 3/10
The result can't be simplified so
the slope is 3/10x
Lin runs 8 laps around a track in 26 minutes.
How many minutes and seconds?
Answer:
3 minutes and 15 seconds per lap.
Step-by-step explanation:
26 ÷ 8 = 3.25
Multiply 3.25 times 60 to get the amount in seconds.
3.25 x 60 = 195
Then, subtract 60 from 195 until you can't subtract 60 anymore.
195 - 60 = 135
135 - 60 = 75
75 - 60 = 15
Add the number of times 60 was subtracted.
60 = 1 minute
So 1 + 1 + 1= 3 minutes.
Then, the 15 left over from 195 after 60 was subtracted from it three times is the amount of seconds.
3 minutes and 15 seconds per lap.
