Answer:
y = 1 · 5^x
Step-by-step explanation:
Use the given values in the given formula and solve for 'a' and 'b'.
y = a·b^x
5 = a·b^1 . . . . . . for (x, y) = (1, 5)
125 = a·b^3 . . . . for (x, y) = (3, 125)
Divide the second equation by the first:
125/5 = (a·b^3)/(a·b^1)
25 = b^2 . . . simplify
5 = b . . . . . . . take the square root
Substituting into the first equation, we can find 'a':
5 = a·5
1 = a . . . . . . . divide by 5
Written in the given form, the equation is ...
y = 1 · 5^x

Answers
Answer:
A. Yes
Step-by-step explanation:
It depends on the definition of "algebraic expression", and especially the meaning of "algebraic" you take to use in your context. If you talk from a high-school perspective, then yes, x+y−π is an algebraic expression, because... well, it looks like algebra and has algebraic-looking characters.
Answer:
A. Yes

m∠WXY+m∠ZXY=90°
m∠WXY+m∠ZXY=180°
m∠WXY+m∠ZXY=m∠WXZ
Pls actually answer and fast
Answers
Answer:
m∠WXY+m∠ZXY=m∠WXZ
Step-by-step explanation:
You don't know the angles to be congruent (equal measures), complementary (measures add to 90 deg), or supplementary (measures add to 180 deg); all you know is that they are adjacent, so the sum of the measures of the two smaller angles equals the measure of the larger outer angle.
Answer: m∠WXY+m∠ZXY=m∠WXZ
The equation that should be true is m∠WXY+m∠ZXY=m∠WXZ
Angles:
The angles should be congruent when it is equal measures, It should be complementary when it measures add to 90 deg, or supplementary when it measures add to 180 degree. Moreover, the sum of the measures of the two smaller angles should be equivalent to the measure of the larger outer angle.

Amelia runs a catering business. Based on her records, her weekly profit can be modeled by P=-2x^2+152x-150P=−2x 2 +152x−150, where xx is the number of meals she caters and PP is her profit.
Answers
Answer:
The least number of meals Amelia needs to cater in order to begin making profit = 38 meals.
Step-by-step explanation:
Given - Amelia runs a catering business. Based on her records, her weekly
profit can be modeled by P= -2x² + 152x - 150, where x is the
number of meals she caters and P is her profit. When P is negative,
Amelia losses money.
To find - What is the least number of meals Amelia needs to cater in order
to begin making profit.
Proof -
As given, P = -2x² + 152x - 150
Now,
Above the break-even point, she only get profit
The break -even point is a point where there is no profit, and no loss.
Now,
For break-even point,
[tex]\frac{dP}{dx} = 0[/tex]
⇒[tex]\frac{d}{dx}( -2x^{2} + 152x - 150) = 0[/tex]
⇒-4x + 152 = 0
⇒- 4x = - 152
⇒4x = 152
⇒x = [tex]\frac{152}{4}[/tex] = 38
∴ we get
If Amelia caters at least 38 meals , then she makes Profit.

Step-by-step explanation:
Rodrigo and Melissa went to the art supply store to buy drawing materials. Rodrigo bought 10
pencils and 7 felt-tip markers for a total of $19.00. Melissa bought 3 pencils and 5 felt-tip markers
for a total of $10.05. Which of the following systems of equations could be used to determine
the cost of one pencil, P, and one felt-tip marker, m?
Answers
Answer:
10P + 7m = 19 .......... 1
3P + 5m = 10.05 .......... 2
Step-by-step explanation:
Let the cost of pencil be represented by P, and felt-tip by m. So that;
Rodrigo bought 10 pencils and 7 felt-tip at the cost of $19.0.
⇒ 10P + 7m = 19 .......... 1
Melissa bought 3 pencils and 5 felt-tip at the cost of $10.05.
⇒ 3P + 5m = 10.05 .......... 2
From equations 1 and 2,
10P + 7m = 19 .......... 1
3P + 5m = 10.05 .......... 2
Multiply equation 1 by 3, and 2 by 10 to have;
30P + 21m = 57 ......... 3
30P + 50m = 100.5 ....... 4
Subtract equation 3 from 4,
30P - 30P + 50m - 21m = 100.5 - 57
29m =43.5
m = [tex]\frac{43.5}{29}[/tex]
= 1.5
m = 1.5
Substitute the value of m in equation 2,
3P + 5m = 10.05 .......... 2
3P + 5(1.5) = 10.05
3P = 7.5 = 10.05
3P = 3
P = 1.0
Thus, the cost of a pencil is $1.0 and that of a felt-tip is $1.5.

Solve x – 2y = 12 if the domain is {–3, –1, 0, 2, 5}.
Answers
Answer:
Step-by-step explanation:
Answer:
answer is below
Step-by-step explanation:
x - 2y = 12
First step is to solve for y, so
[tex]x - 2y = 12[/tex]
Then, subtract x on both sides to isolate the variable, y.
[tex]-2y = -x + 12[/tex]
Divide both sides by -2
[tex]y = \frac{1}{2}x - 6[/tex]
------------------------------------------------------------------------------------------------------
The domain is {-3,-1,0,2,5}
Domain is the set of x values
Range is the set of y values
We are given the domain x, we need to find out the y values using the equation: [tex]y= \frac{1}{2}x - 6[/tex]
[tex]y = \frac{1}{2}(-3) -6 = \frac{-15}{2} = -7.5\\\\y = \frac{1}{2}(-1) -6 = \frac{-13}{2} = -6.5\\\\y = \frac{1}{2}(0) -6 = -6\\\\y = \frac{1}{2}(2) -6 = -5\\\\\\y = \frac{1}{2}(5) -6 = -\frac{7}{2} = - 3.5[/tex]
therefore,
when x is -3: y = -7.5
when x is -1: y = -6.5
when x is 0: y = -6
when x is 2: y = -5
when x is 5: y = -3.5
Range is {-7.5, -6.5, -6 , -5, -3.5}
hope this helps and is right :)

Polygon B is a scaled copy of Polygon A using a scale factor of 5.
How many times larger is the area of Polygon B than the area Polygon A?
Answers
Answer:
25 times
Step-by-step explanation:
Since polygon A is enlarged by a scale factor of 5 to get a Polygon B, therefore,
Area of polygon B : Area of polygon A = 5² : 1²
Area of polygon B : Area of polygon A = 25:1
This, this implies that the area of polygon B is 25 times the area of polygon A.
