how do you write y-2=-1/3(x-7)
Answer:
y= -1/3 + 13/3
Step-by-step explanation:
y-2=-1/3(x-7)
Use the distributive property to simplify the right side of the equation
y-2=(-1/3 * x) + (-1/3 * -7)
y-2=-1/3x + 7/3
Add 2 to both sides get the y by itself. 2 can be expressed as 6/3
(y-2) + 2=(-1/3x + 7/3) + 6/3
y= -1/3x + 13/3
Given x∥y and m∠2=23° .
What is m∠7?
Enter your answer in the box.
Answer:
angle2=23°
angle7=angle5
angle2=angle6
so,angle8=23°
total angle = 180°
angle7=180°-46°=134°÷2=67°
Using corresponding angles are equal property we found that m∠7 = 157°
What are corresponding angles?When two parallel lines are intersected by an transversal line then the pair of angles formed on one same side of transversal on both parallel lines are corresponding angles. As in the figure attached ∠ 1 and ∠5 are corresponding angles.∠4 and ∠8 are also corresponding angles.
Corresponding angles are always equal.
Given that x and y are parallel lines.
Then ∠2 and ∠6 are corresponding angles , therefore m ∠2 = m ∠6
Given that m∠2 = 23°
⇒ m∠6 = 23°
As ∠7 and ∠6 are on same line hence they are supplementary
m∠7 + m∠6 = 180°
⇒m∠7 + 23° =180°
⇒m∠7 =180°- 23° = 157°
Therefore, the measure of angle ∠7 is 157°

How do horizontal and vertical translations each affect the coordinates of the points on a figure.
Answer:
Hi there!
Your answer is:
Perform the translation:
x-10
y-3
Step-by-step explanation:
A translation is how many units X moved left/right and how many units Y moved up/down!
In your case, X went left and Y went down! This means there was a DECREASE in both of these values!
We can determine this by choosing one point and counting how many units it moved.
Lets use the point on figure 1 at (2,5)
Where did it move on figure 2? (-8, 2)
How many units left did it go? 10!
How many units down did it go? 3!
Rigid transformations is preservative of the distance between pairs of points on the figure. Horizontal and vertical translations are rigid motion transformation such that the shape and size of the figure do not change;
The sequence of translation used to move Figure 1 onto Figure 2 is T₍₋₁₀, ₋₃₎
Translate Figure 1, ten units left and three units down to move Figure 1 onto Figure 2
The reason the above sequence is correct is as follows:
Given that translations are rigid motion, we have;
The sequence of translation that will move a point on Figure 1 to the corresponding point on Figure 2 is the same as the sequence of translation used to move Figure 1 to Figure 2
The coordinates of the point on the top right corner of Figure 1 is (6, 8)
The coordinates of the corresponding point in Figure 2 is (-4, 5)
The sequence of translation, T, is given by the difference of the coordinates as follows;
The sequence of translation is T₍₍₍₋₄₎ ₋ ₆₎, ₍₅ ₋ ₈₎₎ = T₍₋₁₀, ₋₃₎
Therefore, the sequence of translation are;
1) Shift Figure 1, 10 units to the left then 2) Shift Figure 1, 3 units down to move Figure 1 to Figure 2

If using the method of completing the square to solve the quadratic equation
x2 - 6x – 34 = 0, which number would have to be added to "complete the
square"?
Answer:
9
Step-by-step explanation:
divide -6 by 2 then square the answer(-3)=9
The solution of x² - 6x – 34 = 0 by completing square method is
⇒x = 3 ±√43
The given quadratic equation is
x² - 6x – 34 = 0,
We know that whole square formula
(p+q)² = p² + q² + 2pq
Now convert the given expression into this form
So adding 9 both sides
⇒ x² - 6x – 34 + 9 = 9
⇒ x² - 6x + 9 = 43
⇒ x² - (2)(3)x + 3² = 43
⇒ (x - 3)² = 43
Taking square root both sides we get
⇒ (x - 3) = ±√43
Add 3 both sides we get
⇒ x = 3 ±√43
Thus the solution of the given quadratic equation is
x = 3 ±√43

In order to evaluate energy demand for heating services, the number of heating degree days are calculated. The number of heating degree days can be calculated by the formula H = 65 - T, where 65 is degrees Fahrenheit, and T is the average of the high and low temperatures for the day. If the high temperature for a day was 51°F and the low temperature for the same day was 45°F, what is the number of heating degree days? A. 17 B. 48 C. 113 D. 14
Given that,
The number of heating degree days can be calculated by the formula H = 65 - T, where 65 is degrees Fahrenheit, and T is the average of the high and low temperatures for the day.
Solution,
The high temperature was 51°F and the low temperature was 45°F.
Average of high and low temperatures for the day is given by :
[tex]T=\dfrac{51+45}{2}\\\\T=48^{\circ} F[/tex]
Now using formula :
H = 65 - T
H = 65 - 48
H = 17
Hence, there are 17 heating degree days.

D. The pattern shows the points are far from the zero line, indicating a good fit for a nonlinear model.
E. The pattern is random, indicating that the model is unable to be determined.
Answer:
The correct option is;
C. The pattern is random, indicating a good fit for a linear model
Step-by-step explanation:
A graph that has the residuals (the difference between the value observed and the value expected (regression analysis) on the vertical axis and the variable that is not affected by the other variables (independent variable) on the x or horizontal axis is known as a residual plot
A linear regression model is suited in a situation where the points are dispersed randomly on both sides of the horizontal axis
Therefore, given that the first point is below the horizontal axis and the next point is above the horizontal axis, while the third and the fourth points are below the horizontal axis, the fifth, sixth, and seventh points are above the horizontal axis and the eighth point is below the horizontal axis, the points are random around the horizontal axis, indicating the suitability of a linear regression model.

C. The pattern is random, indicating a good fit for a linear model.

Draw the image of ABC under dilation whose center is P and scale factor is 4.
Answer:
By plotting points A', B' and C' we can get the dilated image A'B'C'.
Step-by-step explanation:
Let the point P is origin (0, 0), segment AB lies on the x-axis and segment PC on the y-axis,
Coordinates of A, B and C will be (1, 0), (2, 0) and (0, 2).
When triangle ABC is dilated by a scale factor 4 about the origin,
Rule for dilation;
(x, y) → (4x, 4y)
New coordinates of the points A, B and C will be,
A(1, 0) → A'(4, 0)
B(-2, 0) → B'(-8, 0)
