Point-slope form
Complete the point-slope equation of the line through (-4, 8) and (4,4).
Use exact numbers.
WHOEVER ANSWERS RIGHT GETS BRAINIST
There are actually two correct answers, one of them is y-4=-0.5(x-4)
First of all, the slope-intercept that can be derived from the points (-4,8) and (4,4) is y=[tex]-\frac{x}{2} +6[/tex], with -0.5 being the slope. To bring this to point-slope form, you must signify the slope and the coordinate intersection. Since there are two coordinates, there are actually two point-slope equations.

Answer:
N ≤ -7 N > 12
Step-by-step explanation:
The inequality for the given statement is n≤-7 or n>12.
The given statement is a number n is less than or equal to -7 or greater than 12.
What is an inequality?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values.
Now the inequality for the given statement is n≤-7 or n>12.
Graph for the obtained inequality is plotted, given below.
Therefore, the inequality for the given statement is n≤-7 or n>12.

Each deli sandwhiches made uses 8/8 pound of roast beef.Marisa started with 5 pounds of roast beef and now has 2 3/4 pounds left. How many del sandwhiches did she make
Answer:
Marisa has made 6 sandwiches.
Step-by-step explanation:
The pounds of roast beef required to make each sandwiches is [tex]\frac{3}{8}[/tex], and not [tex]\frac{8}{8}[/tex] as erroneously typed in the question.
Given that each deli sandwiches made, uses [tex]\frac{3}{8}[/tex] pounds of roast beef.
Marisa started with 5 pounds, and had 2[tex]\frac{3}{4}[/tex] pounds left.
Thus,
pounds of roast beef used = 5 - 2[tex]\frac{3}{4}[/tex]
= 5 - [tex]\frac{11}{4}[/tex]
= [tex]\frac{20 - 11}{4}[/tex]
= [tex]\frac{9}{4}[/tex]
= 2[tex]\frac{1}{4}[/tex]
Marisa had used 2[tex]\frac{1}{4}[/tex] pounds of roast beef. So that;
the number of del sandwiches made = 2[tex]\frac{1}{4}[/tex] ÷ [tex]\frac{3}{8}[/tex]
= [tex]\frac{9}{4}[/tex] ÷ [tex]\frac{3}{8}[/tex]
= 6
Therefore, the number of sandwiches made by Marisa is 6.

If the scale factor of Figure A to Figure B is 7:2, find the perimeter of Figure A.
Answer:
122.5 units
Step-by-step explanation:
The proportion would be between the perimeters and the given ratio:
7/2 = p/p
Where P is the perimeter of the bigger figure and p is the perimeter of the smaller figure.
Remember that the perimeter is the sum of all sides, using all given values and solving for P, we have
7/2=P/9+5+9+12
7/2=P/35
7(35)/2=P
P=245/2=122.5
Therefore, the perimeter of Figure A is 122.5 units.

The tangent or tanθ in a right-angle triangle is the ratio of its perpendicular to its base. The height of the tree is 39.1027 feet.
What is Tangent (Tanθ)?The tangent or tanθ in a right-angle triangle is the ratio of its perpendicular to its base. it is given as,
[tex]\rm Tangent(\theta) = \dfrac{Perpendicular}{Base}[/tex]
where,
θ is the angle,
Perpendicular is the side of the triangle opposite to the angle θ,
The Base is the adjacent smaller side of the angle θ.
Tan(70°) = Height of the tree/Shadow of the tree
Tan(70°) = Height of the tree/ 32 feet
Height of the tree = 39.1027 feet
Hence, the height of the tree is 39.1027 feet.

9514 1404 393
Answer:
i) exponential; values have a common ratio; f(x) = -2·4^x
ii) linear; values have a common difference; f(x) = 4x -3
iii) exponential; values have a common ratio; f(x) = 4·2^x
Step-by-step explanation:
Sequential, or evenly-spaced, input values will result in output values with a common difference if the function is linear. They will result in output values with a common ratio of the function is exponential.
The initial value, or y-intercept, is the value when x=0. The general form of the formulas is ...
linear: f(x) = (common difference)·x + (initial value)
exponential: f(x) = (initial value)·(common ratio)^x
__
i) The f(x) values have a common ratio of -8/-2 = 4, so the relation is exponential. The initial value is f(0) = -2. The equation is ...
f(x) = -2·4^x
__
ii) The f(x) values have a common difference of 1 -(-3) = 4, so the relation is linear. The initial value is f(0) = -3. The equation is ...
f(x) = 4x -3

iii) The f(x) values have a common ratio of 8/4 = 2, so the relation is exponential. The initial value is f(0) = 4. The equation is ...

A consumer magazine wants to compare the lifetimes of ballpoint pens of three different types. The magazine takes a random sample of pens of each type and conduct an ANOVA test. After the calculation, the F statistic is 1.62 and the p-value is 0.26. What is a correct decision at significance level of 0.1?
Answer: Fail to reject H0
Step-by-step explanation:
Given that:
P value = 0.26
α = 0.1
The values of both p and α can be compared in other to make a decision on whether to reject or fail to reject the Null hypothesis
Decisions :
If the p value > α (fail to reject null)
If p value < α ( Reject null)
In the scenario above :
0.26 > 0.1 ; p value > α
Since the p value is greater than alpha ; we fail to reject the Null
