Answer:
C
Step-by-step explanation:
Answer: The answer is C
Step-by-step explanation:
If you look at the other ratios you can see a common pattern.
The top and the bottom have been multiplied by the same number.
Example: 1/2 and 7/14. Both 1 and 2 were multiplied by seven to make a true proportion.
So answer C was the only one that wasn’t multiplied by the same number.

Write an equation in point-slope form of the line that passes through the given points, then write the equation in slope-intercept form.
Answer:
(-3,5) (6,2) (Plug in these points into (y2-y1)/(x2-x1) to find the slope)
2-5/6-(-3)
-3/9
-1/3 is the slope
y - y1 = m(x -x1) (this is point slope form)
y - 5 = -1/3 (x +3) (you plug in the x &y values from the first set of coordinates)
y -5 = -1/3x -1 (you get to slope intercept form by solving from point slope)
y = -1/3x +4 (this is slope intercept form)
Step-by-step explanation:
3w + 6 - 4w + 3b + 2 +2b=
The answer is 5b - w + 8
Step-by-step explanation:
Answer:
-w + 5b + 8
Step-by-step explanation:
Step 1: Since you're only dealing with addition and subtraction, the easiest method is to convert all subtraction to addition by adding the opposite. There is only one case of subtraction (-4w) which can be changed to adding negative 4w:
3w + 6 + (-4w) + 3b + 2 + 2b
Step 2: Combine like terms to simplify:
3w + (-4w) = -w
3b + 2b = 5b
6 + 2 = 8
Answer:
-w + 5b + 8

The credit remaining on a phone card (in dollars) is a linear function of the total calling time made with the card (in minutes). The remaining credit after 24 minutes of calls is $21.64, and the remaining credit after 35 minutes of calls is $20.10. What is the remaining credit after 45 minutes of calls?
Answer:
The remaining credit after 45 minutes of calls is $18.70
Step-by-step explanation:
Here, we have a linear model to work with
Let us have the coordinates as follows;
(time calling time, credit remaining)
So we have two points as follows;
(24,21.64) and (35,20.10)
The slope will be;
(20.1-21.64)/(35-24) = -1.54/11 = -0.14
So the equation looks like;
y = -0.14x + c
To get the y-intercept, we simply substitute a point
Let us use (35,20.10)
20.10 = -0.14(35) + c
c = 20.10 + 4.9
c = 25
So the full equation is;
y = -0.14x + 25
So for 45 minutes, simply substitute 45 for x
We have this as:
y = -0.14(45) + 25
y = -6.3 + 25 = $18.70

The nutrition label on Erin's box of
animal crackers states that 16 crackers
contain 24 grams of carbohydrates.
Erin ate 12 animal crackers from the
box. What is the number of grams of
carbohydrates in 12 animal crackers?
18 grams because 24 subtract 16 is equal to 6 and if you add 6 to 12 you get 18

Cynthia invests some money in a bank which pays
5% compound interest per year.
She wants it to be worth over £8000 at the end of 3 years.
What is the smallest amount, to the nearest pound, she can invest?
Let ,Cynthia invested $x
Rate = 5%per year
time = 3 year
Amount
A= P(1+r/100)^t
8000=x(1+5/100)^3
8000=x(21/20)^3
x= (8000x8000)/9261
x=6910.7$
Therefore she can invest =$6910.7 =5322.14 pound

Answer:
x = 9
Step-by-step explanation:
56 + 3x + 7 = 90° because these angles are complementary
3x + 63 = 90 subtract 63 from both sides
3x = 27 divide both sides by 3
x = 9

What are the solutions to the quadratic equation 4(x + 2)2 = 36
x= -11 and x = 7
x = -7 and x = 11
OOOO
x= -5 and x = 1
x= -1 and x = 5
Answer:
x = -5 and x = 1
Step-by-step explanation:
4( x2 + 4x + 4 ) = 36
4x2 + 16x + 16 = 36
4x2 + 16x - 20 = 0
x2 + 4x - 5 = 0
Answer:
C. x = -5, and x = 1
Step-by-step explanation:
You have the equation 4(x + 2)2 = 36
You then isolate 4 out of the equation using division on both sides
You are left with (x+2)2 = 9
Next, take square roots
[tex]\sqrt({x} +2) ^{2}[/tex] = [tex]\sqrt{9}[/tex]
This leaves you with x + 2 ± 9
So, x = -2 + 3 = 1
or
x = -2 - 3 = -5

Answer:
-3/8 = x
Step-by-step explanation:
90% sure this is correct but my simple math may be wrong
Answer: x=9
Step-by-step explanation:
x^2-8x-9=0...
we can simplify this by adding 9 to each side... so it turns into this: x^2-8x=9
Then, we can turn x^2 to x*x because we know that anything to the power of two is itself multiplied by itself. So our new equation will be this:
x*x-8x=9
Now we know x has to be 9 because 8 is 1 less than 9. Therefore, our answer would be x (9)...
Let’s test this out... first, let’s substitute x with the number 9:
9^2-8*9-9=0. Simplify this:
81-72-9=0. We can then simplify furthers and we get:
0=0. This means that the equation is true
