Answer:
C. The amount at a given time can be calculated by multiplying the previous amount by a value less than 1.
Step-by-step explanation:
Exponential decay is when an exponential function decreases per x-value. These functions go by a multiplier and are therefore, not linear, so you cannot add or subtract. Because the function is decaying, it is multiplying by an amount less than 1, since the multiplier is 1 - r, where r is the percent.
The first step in solving this eqaution for x uses _ property 2(x + 7) + 3x = 12
Answer:
2×x×7+3x=12
2x+14+3x=12
5x+14=12
5x=12-14
5x=-2
Divided Both Sides By 5
X=-2/5

When three times a number is decreased by 7, the result is 20. What is the number?
The number is?
Answer:
The number is 9
Step-by-step explanation:
• Let the number be x
[tex]{ \tt{3x - 7 = 20}} \\ [/tex]
» Add 7 to either sides following addition rule of equality:
[tex]{ \tt{(3x - 7){ \red{ + 7}} = 20{ \red{ + 7}}}} \\ { \tt{3x = 27}}[/tex]
» Divide either sides by 27:
[tex]{ \tt{ \frac{3x}{ \blue{3 }} = \frac{27}{ \blue{3}} }} \\ \\ { \tt{x = 9}}[/tex]

In the figure below, XZ=35 and YZ=17. Find XY.
Answer:
XY = 18
Step-by-step explanation:
XY → XZ - YZ [ here given XZ is 35 and YZ is 17 ]
XY → 35 - 17 [ subtracting ]
XY → 18 [ final answer ]
Let XY be x
XY+YZ=XZPut values
17+x=35x=35-17x=18XY=18
Andy and Sylvie each incorrectly simpilfied the expression: -3-4(2x-3).
Andy : -14x + 12
Sylvie: -8x - 6
Explain the errors and give the correct answer.
1. Observe problem
2. Simplify
-3-4(2x-3)
expand by distributive property
-3-8x+12
addition and subtraction
-8x+9
I have no idea what Andy And Sylvie were doing, so therefore...
I don't know which brain cell in there head is dysfunctional.
Answer:
-9 - 8x
Step-by-step explanation:
Andy multiplied incorrectly it should have been -4*2x, -4*-3
Sylvie forgot to multiply both sides she did -4*2x but forgot to do -4*-3
The correct answer should be...
-3-4(2x-3)
-3 - 8x + 12
-9 - 8x
Calculate the measures of x y z in the diagram given beloe
Step-by-step explanation:
Solution,
∠IDJ = 70° ( being alternate angle in AB || CD )
∠ IDJ + x = 180° ( being co-interior angle in EF || GH )
or , 70° + x = 180°
or , x = 180° - 70°
x = 110°
Again,
∠BLH = ∠CKG ( Being alternate angle in AB || CD )
y = 110°
Finally ,
z + y = 180° ( Being adjacent supplementary angle )
or , z + 110° = 180°
z = 70°
Thus , x = 110 ° , y = 110 ° and z = 70°

To make a perfect square of v² - 14v , add c such that:
We have:
a = 1 b = - 14 c = b²/ (4a) = (-14)²/ (4 × 1) = 49⇒ v² - 14v + 49 = (v - 7)(v - 7) = (v - 7)²
Answer: 49
OK done. Thank to me :>
Determine whether the following statement is true or false.
The ordered pairs (8,- 9) and (-9,8) name the same point.
Hi!
I can help you with joy!
Are these ordered pairs the same? Do they name the same point?
(8, -9) and (-9,8) are our points.
The x-coordinate of one point is 8, and the x-coordinate of the second point is -9.
The y-coordinate of the first point is -9, and the y-coordinate of the second point is 8.
Thus, these 2 ordered pairs do not name the same point.
The statement is false.
I hope this helps!

A bird of species A, when diving, can travel six times as fast as a bird of species B top speed. If the total speeds for these
two birds is 259 miles per hour, find the fastest speed of the bird of species A and the fastest speed of the bird of species B.
What is the fastest speed of the bird species B in miles per hour and the fastest speed of the bird of species A in miles per hour
Answer:
37 mph, 222 mphStep-by-step explanation:
Let the speed of bird of species A is x and speed of B is y.
The equations:
x + y = 259x = 6ySubstitute and solve for y:
6y + y = 2597y = 259y = 259/7y = 37Find x:
x = 6*37 = 222
[tex]x[/tex]will be the speed of species b and [tex]4x[/tex] will be the speed of species a:
[tex]x + 4x = 180[/tex]
[tex]5x = 180[/tex]
[tex]x = \frac{180}{5}[/tex]
[tex]x = 36 \: m/h[/tex]
If species b has a speed of [tex]36 [/tex]m/h, the speed of species a is [tex]4[/tex]times that:
[tex]4 \times 36 = 144 m/h[/tex]
Answer :—
[tex]A = 36 \: m/h [/tex]
[tex]B = 144 \: m/h[/tex]

Karen wants to order lunch for herself and some friends. Sam’s Deli charges $5 per sandwich plus $8 for delivery. Quick Lunch Deli charges $6 per sandwich plus $4 for delivery. How many sandwiches would Karen have to purchase to make the total cost of lunch the same?
Answer:
4 sandwichesStep-by-step explanation:
Let the number of sandwiches is x.
We have the following equation:
5x + 8 = 6x + 46x - 5x = 8 - 4x = 4Answer: The answer is She would have to buy 20 sandwiches. which is $200. She's buying those rich sandwiches.
Step-by-step explanation: I used a graph and added till I got the number the same for both which was 200 I hope this helps have a great day!

Which expression is equivalent to 3^-2 times 5^-2
a. 1/15^2
b. 1/15^-2
c. 15^4
d. 15^-4
Answer:
The answer would be A)
Step-by-step explanation:
3^-2 = 1/9
5^-2 = 1/25
1/9 * 1/25 = 1/225
15^2 = 225
meaning,
3^-2 * 5^-2 = 1/15^2
