What is the equation
Answer:
D.) y = 2x + 2
Step-by-step explanation:
First, we need to find the slope.
Lets use the points (0, 2) and (-2, -2).
Using the formula for calculating slope, we get 2 as our slope.
Since the equation should be in slope-intercept form, we use this formula.
y = mx + b
We'll use our first point (0, 2) to substitute for x and y and use 2 to substitute for m (slope):
2 = 2(0) + b
2 x 0 = 0
2 = 0 + b
-0 = -0
= 2 = b
Now, substitute b for 2 for 2 for m.
= y = 2x + 2.
Hope this helps!

When does a negative exponent not move the base to the denominator
Answer:
If the base and the negative exponent is in the denominator already
Step-by-step explanation:
Normally, a base with a negative exponent moves to the denominator.
Example: (2^-3 = 1 / (2)^3 = 1/8)
However, if the base and the negative exponent is already in the denominator, the base would move to the numerator and the exponent would become positive.
Example: 2 / (3)^-3 = 2 * 3^3 = 2 * 27 = 54

(A) As t increases, the parabola shifts away from the y-axis and increases quickly. The y-axis is where the symmetry lies.
(b) The curve is a parabola that begins at the centre and expands upward.
(c) The curve has a sharp x-direction oscillation and a y-direction oscillation.
(d) The slope oscillates quickly in one direction (the x-axis), but more slowly in the other.
(e) The trajectory travels in the direction of positive y while oscillating in the x-direction.
(f) As the trajectory deviates from the center, it oscillates.

In six years Mariya will be will be as old Vikram is now.In 2 years,Vikram will be three times older than Maria. Find there ages
9514 1404 393
Answer:
Mariya is 1Vikram is 7Step-by-step explanation:
Let m and v represent Mariya's and Vikram's agess now.
m + 6 = v . . . . . . in 6 years Mariya will be as old as Vikram is now
(v +2) = 3(m +2) . . . . in 2 years, Vikram will be 3 times Mariya's age
Using the first equation to substitute for v in the second equation, we have ...
m +6 +2 = 3m +6
2 = 2m . . . . . subtract m+6
1 = m
Mariya is 1; Vikram is 1+6 = 7.
Lines, Angles, and Triangles please help solve
1) Note that the angles on the North Side of the Intersection are described as follows:
a) ∠z and ∠x are Supplementary
b) ∠y and ∠x are also are Supplementary
c) ∠65° ≅ ∠x because they are opposite angles
2) Davis Avenue and Rock Island Road are perpendicular. The measures of the four angles formed by the intersection of these two roads are 90° each.
4) a) The measure of ∠A = 25°
b) The relationship between Memorial Boulevard and Rock Island Road is that they are perpendicular to one another.
A supplementary angle is an angle that, when added to another angle, results in a sum of 180 degrees. Since ∠z and ∠x are angles on a straight line and ∠y and ∠x are also angles on a straight line, and angles on a Straightline sum up to 180°, therefore:
1) ∠z and ∠x, as well as ∠y and ∠x are all Supplementary angles respectively.
2) Davis Avenue and Rock Island Road are perpendicular. The measures of the four angles formed by the intersection of these two roads are 90° each. When two lines intersect at a point and each of these lines bisects the other, they form four angles of equal measure. These angles are all 90 degrees, so the angles formed by two lines that bisect one another are 90 degrees on each side.
4)
a) The measure of ∠A = 25° this is because
ΔPNA = Right Angled Triangle (See attached Image)
The sum of angles in a Triangle = 180°
Since m∠P = 65° - Given
m∠N = 90°
Thus,
m∠A = 180 - 90 - 65
m∠A = 25°
b) The relationship between Memorial Boulevard and Rock Island Road is that they are perpendicular to one another. This is because they both create a 90 degree angles between each other.
Perpendicular lines are two lines that intersect at a right angle (90 degrees). This means that the lines form four angles at the point of intersection, and each of these angles measures 90 degrees.
Note that perpendicular lines can be found in many different contexts, such as in geometry, engineering, and architecture. In two-dimensional geometry, perpendicular lines are often represented by the symbol ⊥.

The coordinates of the point 3/10 of the way from A to B are _
Answer:
(-1, -4.8)
Step-by-step Explanation:
Let the point be P, which is 3/10 of the way from A to B. This means, it divides P into AP and PB in the ratio, 3:10 = AP/PB = 3/10.
Apply the formula for internal division to find the coordinates which is given as:
\( x = \frac{mx_2 + nx_1}{m + n} \)
\( y = \frac{my_2 + ny_1}{m + n} \)
Where,
\( A(-4, -8) = (x_1, y_1) \)
\( B(9, 6) = (x_2, y_2) \)
\( m = 3, n = 10 \)
Plug in the necessary values to find x and y coordinates for point P
\( x = \frac{mx_2 + nx_1}{m + n} \)
\( x = \frac{3(9) + 10(-4)}{3 + 10} \)
\( x = \frac{27 - 40}{13} \)
\( x = \frac{-13}{13} \)
\( x = -1 \)
\( y = \frac{my_2 + ny_1}{m + n} \)
\( y = \frac{3(6) + 10(-8)}{3 + 10} \)
\( y = \frac{18 - 80}{13} \)
\( y = \frac{-62}{13} \)
\( y = \frac{-62}{13} \)
\( y = -4.8 \)

the perimeter of a triangle is 32 feet. One side of the triangle is 11 feet longer than the second side. The third side is 9 feet longer than the second side. Find the length of each side.
Answer:
One side - 15 feet
Second side - 4 feet
Third side - 13 feet
Step-by-step explanation:
Let's call the sides A B and C, respectively.
We know that:
A = B + 11
C = B + 9
and that
A + B + C = 32
Please note that we have 3 equations and 3 unknowns. We can solve this, we'll use substitution.
A + B + C = (B + 11) + B + (B + 9) = 32
3B + 20 = 32
3B = 12
B = 4
The sides have lengths of 4+11 = 15, 4 and 4+9 = 13. This is in fact a proper triangle (because the shorter sides add up to more than the longer side).

A glacier in Alaska moves about 29.1 meters a day. About how much farther will it move in 1,000 days than it will move in 100 days?
Answer:
26190 meters
Step-by-step explanation:
The distance moved by a glacier = 29.1 meter per day
For 100 days, the distance moved = 29.1 meter per day * 100 days = 2910 meters
For 1000 days, the distance moved = 29.1 meter per day * 1000 days = 29100 meters
Therefore the distance farther it move in 1,000 days than it will move in 100 days = distance moved in 1000 days - distance moved in 100 days
farther distance = 29100 meters - 2910 meters = 26190 meters
We will find that the glacier moves 10 times more in 1,000 days than in 100 days.
We know that the glacier moves about 29.1 meters per day.
Then we need to find how much it moves in 1,000 days and in 100 days, we will get:
In 1,000 days it moves: (29.1 meters/day)*1,000 days = 29,100 metersin 100 days it moves: (29.1 meters/day)*100 days = 2,910 meters.To find how much farter the glacier moves in 1,000 days than in 100 days we need to take the quotient between the above two distances:
29,100 meters/2,910 meters = 10
So the glacier moves 10 times more in 1,000 days than in 100 days.

ACF is a 30º-60º-90º triangle because of the following:
1) Based on a theorem, in a 30°-60°-90° triangle the sides are in the ratio 1 : 2 : \(\sqrt{3}\)

A baker makes apple tarts and apple pies each day. Each tart, t, requires 1 apple, and each pie, p, requires 8 apples. The baker receives a shipment of 184 apples every day. If the baker makes no more than 40 tarts per day, which system of inequalities can be used to find the possible number of pies and tarts the baker can make?
Answer: t<40
8p+<184
Step-by-step explanation:
The inequalities representing the given condition will be \(t\leq40\) and \(8p+t\leq184\).
Given information:
A baker makes apple tarts and apple pies each day.
The baker receives a shipment of 184 apples every day.
A tart requires 1 apple and a pie requires 8 apples.
Let t be the number of tarts made each day and p be the number of pies made each day.
The baker makes no more than 40 tarts per day. So, the condition can be written as,
\(t\leq40\)
And the condition for each day apple delivery can be written as,
\(8p+t\leq184\)
Therefore, the inequalities representing the given condition will be \(t\leq40\) and \(8p+t\leq184\).
