Answer:
Less Than
Step-by-step explanation:
Given;
The equation of one exponential function is
[tex]g(x)=-9(0.1)^x[/tex]
Solve for (y-intercept of g(x))
⇒ [tex]g(x) = -9(0.1)^x[/tex]
⇒ [tex]y = -9(0.1)^0[/tex]
⇒ [tex]y = -9[/tex]
Note;
The y-intercept is when x = 0
y-intercept of h(x) = 6
Hence, knowing that -9 < 6.
Thus, y-intercept of g(x) is less than the y-intercept of h(x).

Answer:
less than
Step-by-step explanation:
The y-intercept is when x = 0
Function g(x)
[tex]g(x)=-9(0.1)^x[/tex]
Input x = 0 into the equation and solve:
[tex]\implies g(0)=-9(0.1)^0=-9[/tex]
Therefore, the y-intercept of g(x) is (0, -9)
Function h(x)
From inspection of the table, the y-intercept of h(x) is (0, 6)
As -9 < 6, the y-coordinate of the y-intercept of g(x) is less than the y-coordinate of the y-intercept of h(x)

C. Having no repeating inputs.
D. Having a positive average rate of change.
EXPLAIN
Answer:
Linear functions are those whose graph is a straight line. A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y. a is the constant term or the y intercept.

Beatrice traveled the last 220 miles of the trip at 55 miles per hour. The entire trip
covered 430 miles and took 7 hours. What was her rate for the first 210 miles?
Answer:
Beatrice traveled the last 220 miles of the trip at 55 miles per hour. The entire trip covered 430 miles and took 7 hours. What was her rate for the first 210 mile?
Let Beatrice's average speed for the first 210 miles = S
220/55 + 210/S
Solve for S:
4 + 210/S = 7
Bring 4 + 210/S together using the common denominator S:
(2 (2 S + 105))/S = 7
Multiply both sides by S:
2 (2 S + 105) = 7 S
Expand out terms of the left hand side:
4 S + 210 = 7 S
Subtract 7 S + 210 from both sides:
-3 S = -210
Divide both sides by -3:
Answer: |S = 70 - miles per hour, her speed for the first 210 mStep-by-step explanation:
x²+x-56=0 quadratic equations
Step-by-step explanation:
To solve the equation, factor x
2
+x−56 using formula x
2
+(a+b)x+ab=(x+a)(x+b). To find a and b, set up a system to be solved.
a+b=1
ab=−56
Since ab is negative, a and b have the opposite signs. Since a+b is positive, the positive number has greater absolute value than the negative. List all such integer pairs that give product −56.
−1,56
−2,28
−4,14
−7,8
Calculate the sum for each pair
−1+56=55
−2+28=26
−4+14=10
−7+8=1
The solution is the pair that gives sum 1.
a=−7
b=8
Rewrite factored expression (x+a)(x+b) using the obtained values.
(x−7)(x+8)
To find equation solutions, solve x−7=0 and x+8=0.
x=7
x=−8

Step-by-step explanation:
In what ratio is the line joining the points.
(-1,8) and (5,2) divided by the point (3,4)
Answer:
2:1
Step-by-step explanation:
use k:1 as ratio, and then apply the section formula.
let's use the x co-ordinate pf the point in between the other two which is=(3)
section formula says,
x=mx2 + nx1/(m+n)
m=k , n=1
substitute all the values,
3=5k+(-1)/(k+1)
take k+1 to left side,
3(k+1)=5k-1
3k+3=5k-1
5k-3k=3+1
2k=4
(÷2)
k=2
hence, the ratio = 2:1
Which graph represents the inequality 3y−5x>−6?
Answer:Top Left
Step-by-step explanation:
Graph A represents the given inequality 3y−5x>−6. Option A is correct.
From the graphs, the graph is to choose which best describes the inequality 3y−5x>−6
What is inequality?Inequality can be defined as the relation of an equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.
Given inequality,
3y−5x>−6.
Since the inequality contains only greater than sign, so options B and C will be omitted because both the graphs show boundary conditions that are wrong for the given inequality.
Now, graph A and D show now boundary condition and shaded portions
3y−5x>−6
Since the inequality is shown greater than -6 so the inequality will start from a negative y toward the positive y i.e.
3y−5x > −6
3y > 5x - 6
y > (5x - 6)/3
The above expression shows the value of y lies above the line y =5x/3-2 which implies graph A is correct.
Thus, Graph A represents the given inequality 3y−5x>−6. Option A is correct.

A medical delivery services charges $10 for a house call plus $0.50 per mile. The situation is represented by the equation c=0.5m+10 where m represents the number of miles the delivery is from the office and c represents the cost of the delivery. Calculate the total cost of a medical service delivery if the number of miles driven is 75.5 miles. Write your answer as an ordered pair (m,c).
Answer:
$47.75
Step-by-step explanation:
Where are given that the cost of medical service delivery is given by the expression
c=0.5m+10
m= the number of miles
when the number of miles is 75.5 mile we want to find the cost
put m=75.5 in the expression
c=0.5(75.5)+10
solving for c we have
c=37.75+10
c=47.75
Therefore the cost will be $47.75 for a distance of 75.5miles

Answer: $50 + $2.49x = $67.43
Step-by-step explanation:
Let the case of water bought be represented by x.
We are informed that Sam's Club has a special that charges $2.49 per case of water and that Vinny wants to pay that price, but needs to purchase a membership first, which costs $50 and that Vinny eventually spent $67.43.
The equation that represents the number of cases of water that Vinny bought at Sam's club will be:
$50 + $2.49x = $67.43

The length of a rectangle is twice its width. The perimeter of the rectangle is 131 feet.
_____=_____
Answer:
[tex]131=6w[/tex]
Step-by-step explanation:
[tex]l=length\\\\w=width\\\\\Longrightarrow l=2w\\\\\Rightarrow Perimeter=l+l+w+w\\\\P=2l+2w\\\\P=2(2w)+2w\\\\P=4w+2w\\\\P=6w\\\\P=131\\\\131=6w\\\\w=\frac{131}{6}\\\\w=21.8\overline{3}\\\\l=43.\overline{6}[/tex]
Answer:
A) l = 2 * w
B) 131 = 2l + 2w
B) 2l = 131 -2w
B) l = 65.5 -w
Substituting this into A)
65.5 -w = 2w
3w = 65.5
width = 21.8333333333
length = 43.6666666666
Double - Check
131 = 2 * 21.833333333 + 2 * 43.6666666666
131 = 43.6666666 + 87.33333333
