10 miles in 30 minutes would mean Julia was riding at 20mph.
5 miles in 12 minutes would mean Alex was riding at 25mph which means Alex would've had the greater average speed.
miles per hour is a good measure for this scenario because a hour is 60 minutes and the numbers 12 and 30 go into 60 cleanly.
12*5=60
30*2=60

Tell whether each equation is in slope-intercept, point-slope, or standard form.
d. y-3=4 x
y-3=4 x is in point-slope form, it is neither in slope-intercept form nor standard form.
What is a slope of line?A line's steepness and direction are determined by the slope of the line. Without actually using a compass, determining a line's slope in a coordinate plane allows one to anticipate whether a line is parallel, perpendicular, or not.
The change in a line's y coordinate relative to its change in x coordinate is referred to as the line's slope. Δy is the net change in the y coordinate, while Δx is the net change in the x coordinate.
Therefore,
m = y₂-y₁/x₂-x₁ (where m denotes the slope) can be used to express how the y coordinate changes in relation to the x coordinate.
Be aware that tan ∅ = y/x
We also refer to this tan as the line's slope
We know that point-slope form = y₂ - y₁ = m(x₂ - x₁)
the equation looks like this in point-slope form ⇒ y-2= 4(x-0)
Here, the points are (x, y) and the points the line is passing through is
(0, 2)
y-2= 4(x-0) is in point-slope form, it is neither in slope-intercept form nor standard form.

Evaluate each function for the given value of x , and write the input x and output f(x) as an ordered pair.
f(x)=2 x-33 for x=9
f (9) = 15 is the output for the given input .
How can you tell whether a function is linear or not?
Looking at a function's graph will reveal if it is linear or not with the greatest ease.When a linear function is plotted on a graph, a straight line is formed. A nonlinear function is curved in some way; it does not form a straight line.f(x)= 2 x - 33
Put x = 9 ⇒ 2 × 9 - 33
⇒ 18 - 33
⇒ 15

A translation may either be seen as the addition of a constant vector to each point or as the movement of the origin of the coordinate system. Both of these interpretations are valid.
Generally, You need to turn the ship such that all of the sides are aligned parallel to one another.
Move the vertices around in the shape until they are aligned properly.

Kayla rode her bike 75 miles home from college one weekend and then rode the bus back to college. It took her 2 hours less to ride back to college on the bus than it took her to ride home on her bike, and the average speed of the bus was 10 miles per hour faster than kayla’s biking speed. Find kayla’s biking speed
When Kayla rode her bike home from college one weekend, her biking speed is 15 miles per hour
Speed is defined as the ratio between the distance and the amount of time an object traveled.
speed = distance/time
If the average speed of the bus was 10 miles per hour faster than Kayla’s biking speed, we have:
average speed of the bus = 10 mph + biking speed
let x = biking speed
y = average speed of the bus
y = 10 + x
Covering the same distance of 75 miles, calculate the time it took her riding the bus and the bike.
time = distance/speed
time riding the bus = 75 miles/(10 + x)
time riding the bike = 75 miles/x
If it took her 2 hours less to ride back to college on the bus than it took her to ride home on her bike
time riding the bus = time riding the bike - 2
75 miles/(10 + x) = (75 miles/x) - 2
75/(10 + x) = (75 - 2x)/x
Multiplying both sides by x(10 + x),
x(10 + x)[75/(10 + x)] = x(10 + x)[(75 - 2x)/x]
75x = 750 - 20x + 75x - 2x^2
2x^2 + 20x - 750 = 0
x^2 + 10x - 375 = 0
(x - 15)(x + 25) = 0
x = 15 ; x = -25
Since we cannot have negative amount of time, choose x = 15.
Hence, Kayla's biking speed is 15 miles per hour.

Evaluating the expression b(2b - a) for a = 3 and b = -5 is equal to 65.
An algebraic expression is a number, variable, or the combination of both and operational symbols. On the other hand, an equation is the equality of two expressions separated by "=".
To evaluate an expression or an equation means to substitute a value to the variable and perform the arithmetic operations included.
Given the expression b(2b - a), substitute the value of the variable a and the value of variable b.
b(2b - a)
-5[2(-5) - (3)]
Performing the arithmetic operations, we can have the value of the expression.
-5[2(-5) - (3)]

Three angles fit around a .2 of the angles are 115° and 53° work out the size of the third angle which of the word below describes the third angle right angle obtuse angle reflex angle or acute angle
Three angles fit around a point, two of the angles are 115° and 53° , then the size of third angle would be 192° and it would be a reflex angle.
The sum of the angles around a point is 360 °
If the two angles are 115° and 53° , the sum of the two angles would be 168°
If we reduce the sum of the two angles from the total 360° , we get the size of third angle as 192°
As the size of third angle is more than 180° , so the name of the third angle is reflex angle because right angle is measured 90° , obtuse angle is measured more than 90° but less than 180° , reflex angle is measured more than 180° but less than 360° and acute angle is measured less than 90 °
