Answer:
0?
Step-by-step explanation:
Original Equation:
-10b + 5 = 7b + 5
Add 10b to both sides
5 = 17b + 5
Subtract 5 from both sides.
0 = 17b
Divide both sides by 17
b = 0

On May 21 there will be approximately 728,500 nothing mosquitoes.
What is an exponential function?In Mathematics, an exponential function can be modeled by using this mathematical expression:
f(x) = ab^x
Where:
a represents the initial value or y-intercept.x represents time.b represents the rate of change.Based on the information provided above, an exponential function which models the situation is given by:
y = 200,000(1.09)^x
For the time between May 7 and May 21, we have:
Time = May 7 to May 21 = 15 days.
Substituting the given parameters into the exponential function formula, we have;
y = 200,000(1.09)^15
y = 200,000(3.6425)
y = 728,500 mosquitoes.

(x, y)→(x + 4, x − 2)
(x, y)→(x − 7, y + 7)
(x, y)→(x + 7, y − 7)
Answer:
The answer is B I think.
Answer:
D
Step-by-step explanation:
The reason is because y is rise or how far you go down while x is whether you go right or left. Lets use point D for example if we move 7 to the right x is positive then we lower 7 then y is negative that's why I think it's correct.

Lines AB and CD are straight lines. Find x and y. Give reasons to justify your solutions.
Answer:
x=18.5
y=37
Step-by-step explanation:
90+2y+16=180
106+2y=180
2y=74
y=37
16+4x+90=180
106+4x=180
4x=74
x=18.5
Answer:
y = 37, x = 18.5
Step-by-step explanation:
O = 16 because of the vertical angles rule. The degrees on a straight line is 180 degrees. That means that because AB is a straight line, 2y + O + 90 = 180. We also know that CD are straight, so O + 4x +90 = 180.
Now we solve for x and y:
2y + O + 90 = 180
2y + 106= 180
2y = 74
y = 37
O + 4x +90 = 180
16 + 4x +90 = 190
4x + 106 = 180
4x = 74
x = 18.5

Find the slope of (1,8) and (3, 12)
Answer: 4/2
Step-by-step explanation:
subtract 12-8 , it would be 4
then 3-1 , it would be 2
The slope of (1,8) and (3,12) is 2 and this can be determined by using two-point slope formula and also using the given data.
Given :
Points -- (1,8) and (3,12)
The following steps can be used in order to determine the slope of (1,8) and (3,12):
Step 1 - The two-point slope formula can be used in order to determine the slope of (1,8) and (3,12).
Step 2 - The two-point slope formula is given by:
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
Step 3 - Now, substitute the values of the point [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] in the above formula.
[tex]\rm m =\dfrac{12-8}{3-1}[/tex]
m = 2

Suppose A and B are points. What is the maximum number of distinct lines that contain both A and B?
Answer:
Step-by-step explanation:
there would be one distinct line
Points and lines are both undefined terms of geometry.
The maximum number of distinct lines that contain both A and B is 1
From the question, we have:
[tex]Points = 2[/tex] --- i.e. A and B
For any given 2 points, only one line can run through the points. In other words, only one line can run through point A and point B
The line can:
Start from point A and end at point BStart from point B and end at point BRun through both pointsHence, the maximum number of distinct lines that contain both A and B is 1

Point A is the midpoint of side XZ and point B is the midpoint of side YZ. Triangle X Y Z is cut by line segment A B. Point A is the midpoint of side X Z and point B is the midpoint of side Y Z. The length of X Y is 5 x minus 7, the length of A B is x + 1, and the lengths of X A and Z A are 2 x minus 2. The lengths of Y B and B Z are congruent. What is AX? 2 units 4 units 6 units 8 units
Answer:
B. 4unitsStep-by-step explanation:
Find the diagram attached. The diagram is a similar triangle.
From the diagram, XZ/XY = CA/AB
Given XZ = 2x-2+2x-2 = 4x-4
XY =5x-7
CA = 2x-2
AB= x+1
On substituting this parameters into the formula to get x first
4x-4/5x-7 = 2x-2/x+1
cross multiply
(4x-4)(x+1) = 5x-7(2x-2)
open the parenthesis
4x²+4x-4x-4 = 10x²-10x-14x+14
4x²-4 = 10x²-24x+14
10x²-4x²-24x+14+4 = 0
6x²-24x+18 = 0
x²-4x+3 = 0
x²-3x-x+3 = 0
x(x-3)-1(x-3) =0
(x-3)(x-1) = 0
x = 3 and 1
Next is to get length AX.
Given AX = 2x-2
Substitute x = 3 into the expression
AX = 2(3)-2
AX = 6-2
AX = 4 units
Hence the measure of length AX is 4 units

Step-by-step explanation:
Parallel lines have equal slopes.
Calculate the slopes m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 1, 2) and (x₂, y₂ ) = (2, 3)
m = [tex]\frac{3-2}{2+1}[/tex] = [tex]\frac{1}{3}[/tex]
Repeat with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (3, 1)

2) 9 4/5
3) 1 1/5
4) 9.5
Answer:
21 [tex]\frac{3}{5}[/tex]in/hr
Step-by-step explanation:
Distance of snow fall = 3ft
Time taken = 1[tex]\frac{2}{3}[/tex]hrs
Unknown:
Rate of snowfall = ?
Solution:
The rate of the snowfall is the same as the speed of the fall;
Rate of snowfall = [tex]\frac{distance of snowfall}{time}[/tex]
Convert the ft to inches;
1ft = 12inches
3ft = 3 x 12 = 36inches
Input the parameters and solve;
Rate of snowfall = [tex]\frac{36}{\frac{5}{3} }[/tex] = 36 x [tex]\frac{3}{5}[/tex] = 21 [tex]\frac{3}{5}[/tex]in/hr
