1) true
2)false
3)false
4)true
5)true
Step-by-step explanation:
The account is starting off with 1500, so that will be the start value. Since it is simple interest, it will always be gaining 4 percent of 1500. Let's find 4 percent of 1500.
1500×.04= 60
The account will be growing by $60 every year.
1500+60x=y
X is the number of years. We can find the interest earned by multiplying 5, since that is the number of years we are trying to find, and 60, since that is the interest.
60×5= 300
The interest earned is $300 over 5 years.
Now let's find the balance of the account after 5 years.
1500+ 60(5)=y
1500+300=y
1800=y
The balance of the account will be $1,800 after 5 years.
Answer:
P=2T-8, if T=12, Preston, P=24-8=16 years old.
Hope this helps ;)
For this question here are the formulas,
Let T be the number of 10's
Let F be the number 5's
Let us find the 10's first by this formula.
<span>5(124 - T) + 10T = 840
</span>620-5T + 10T = 840
then
5T = <span>220
</span>5 5
T=44
<span>Now let's find the F using this formula.
</span>
5F + 10T = 840
Sustitute T
5F + 10(44) = 840
<u>5F</u> = <u>400
</u>5 5
F = 80
to Check
F + T = 124
80 + 44 = 124
Answer:
33. D.1/3
34. D. y= x+4
35. Slope= -2/3 Y-intercept= -6
Step-by-step explanation:
For number 33. D. 1/3 is the correct answer.
<em>Start at the point (0,2) Then, Go up 1 and Right 3. </em>
<em>As a result, you land in the point (3,3) This proves that the slope is 1/3.</em>
Note: the line is increasing and going upwards, so the slope is positive.
For number 34. D. y=x+4 is the correct answer.
<em>When writing an equation of a line, the correct format is y=mx+b. We are given both m and b. So all we have to do is plug these values into the equation y=mx+b. As a result, we get y=1x+4, which also means y=x+4</em>
For number 35. The Correct answer is: Slope= -2/3 Y-intercept= -6
<em>For this question I can't see all the answer choices but I know that the Slope is -2/3 and the Y-intercept is -6. Here's why: First you need to transform the equation 2x+3y=-18 into y=mx+b format. To do this, subtract -2x from both sides of the equation and you are left with 3y=-18-2x. You can flip -18 and -2x which makes the equation 3y=-2x-18. The next step is to divide both sides of the equation by 3, which gives you y=-2/3x-6. This means </em>Slope= -2/3 and Y-intercept= -6
