Answer:

r = 4

Step-by-step explanation:

Calculate the slope m using the slope formula and equate to 5

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (7, r ) and (x₂, y₂ ) = (8, 9)

m = \frac{9-r}{8-7} = \frac{9-r}{1} = 9 - r = 5 ( subtract 9 from both sides )

- r = - 4 ( multiply both sides by - 1 )

r = 4

Jason begins at the start of a path and rides his bike 11 12 miles on the path. The path is 12 14 miles long. Enter the distance
nikitadnepr [17]

Answer:

Number of miles remaining for Jason to reach end of the path = 3/4 miles

Step-by-step explanation:

Total distance of the path = 12 1/4 miles

Distance reached by Jason's bike on the path = 11 1/2 miles

Enter the distance, in miles, Jason must ride to reach the end of the path.

Number of miles remaining for Jason to reach end of the path = Total distance of the path - Distance reached by Jason's bike on the path

= 12 1/4 miles - 11 1/2 miles

= 49/4 - 23/2

= (49-46) / 4

= 3/4 miles

Number of miles remaining for Jason to reach end of the path = 3/4 miles

What is the least possible degree of the polynomial graphed above?
Degger [83]

Considering it's critical points, it is found that the least possible degree of the polynomial graphed above is of 4.

<h3>What are the critical points of a function?</h3>

The critical points of a function are the values of x for which:

f^{\prime}(x) = 0

In a graph, they are the turning points, and if a function has n critical points, the least possible degree is of n + 1.

In this problem, the function has 3 turning points, at x = -3, between x = -3 and x = 3, and at x = 3, hence the least possible degree of the polynomial graphed above is of 4.

George has $23 to spend on art supplies.He wants to buy markers,paper, and glue.If the total cost of the markers and paper is mo
Lostsunrise [7]
The inequality that would represent the amount that could be spent on glue, p is:

p <$9

You will determine this by subtracting 23 and 14 to get $9.  If this is $9, that means you will spend less that that, because you will spend more that the $14 on the other supplies.

NEED ASAP 7TH GRADE MATH
vesna_86 [32]

Answer:

67.3684% or 67%

Step-by-step explanation:

percent increase = 100 X (final amount-initial amount)/(initial amount)

so

percent increase = 100 X (159-95)/95

159 - 95 = 64

64/95 = 0.6736842105263158

0.6736842105263158 X 100 = 67.36842105263158
