I think this is the answer
Answer:
y = 2x - 5
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
to calculate m use the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (- 2, - 9) and (x₂, y₂ ) = (6, 7)
m = (7 + 9) / (6 + 2) = 16/8 = 2
y = 2x + c ← is the partial equation
to find c use either of the 2 points
using (6, 7), then
7 = 12 + c ⇒ c = 7 - 12 = - 5
y = 2x - 5 ← equation in slope-intercept form
Under the given conditions Maribel can reach her goal of the skate.
A collection of numbers and operations is an expression in mathematics. The following are the parts of a math expression that do a math operation:
Operator: An operator is a symbol that denotes a math operation, such as:
division, addition, subtraction, and multiplication.
Given total distance to skate = 1 and 1/2 = 3/2 miles
skates in morning = 9/10 miles
distance left to skates = 3/2 - 9/10
multiply and divide by 5 in 3/2 = (3 x 5)/(2 x 5) = 15/10
distance left to skates = 15/10 - 9/10 = 6/10
distance left to skates = 6/10 = 3/5
and skate 2/3 of 9/10 in afternoon,
2/ 3 x 9/10 = 3/5
so the left distance is 3/5 which she skates in the afternoon.
Hence she will reach her goal.

Answer:
Jeanette would be on time on 85% of her trips.
Step-by-step explanation:
If the light rail service claims to be on time 98% of the time, it should arrive on time at least 39 of 40 times, as 40 x 98 / 100 is equal to 39.2. In consequence, as Jeanette's service arrived late in 6 of over 40 times, we can affirm that what the light rail stated was incorrect. A delayed service in 6 of 40 times has a punctuality rate of 85%, since 6 is the 15% of 40 (40 x 15 / 100 = 40).
Answer:
4058/54 is equal to about 75.15
the greatest place value is 70 (tens) and the quotient is about 75.15
