Answer:

13.205

Step-by-step explanation:

19.46 divided by 14

= 1.39

Multiply 1.39 with gallons given:

=(9.5)(1.39)

= 13.205

Therefore, it would cost $13.21 to get 9.5 gallons of gas.

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: (1, 3)

Step-by-step explanation:

Answer:

6x+4y+2x-4y = 18+(-10)

8x = 8

x = 1

6x+4y = 18

6*1+4y = 18

4y = 18-6

4y = 12

4y/4=12/4

y= 3

Using proportions, it is found that she can claim amounts greater than $2657.4 as a medical deduction.

A proportion is a fraction of a total amount.

In this problem, her adjusted gross income is $35,432, and she can claim deductions for amount's that exceed 7.5% of this, hence:

0.075 x 35,432 = $2657.4.

She can claim amounts greater than $2657.4 as a medical deduction.

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

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.

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

131 = 131

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).

~Learn with lenvy~

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)

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
