Step-by-step explanation:
14w+3p=70.50
10w+7p=62.50
Which statements are true in explaining why it makes sense that the solution of this system is also a solution to 4w+(−4p)=8.00? Select all that apply.
Because 10w+7p is equal to 62.50, subtracting 10w+7p from the left side of 14w+3p=70.50 and subtracting 62.50 from its right side keep the two sides equal.
The equation 4w+(−4p)=8.00 is the result of adding the two equations in the system and then dividing the result by 6.
The equation 4w+(−4p)=8.00 is the result of subtracting the second equation in the system from the first equation.
The equation 4w+(−4p)=8.00 represents the difference between Mai's sales and Tyler's sales, or the result of subtracting Tyler's sales from Mai's.
The left side of the equation 4w+(−4p)=8.00 shows the difference in terms of the items sold. The right side shows the difference in dollars. The cost per wreath, w, and the cost per potted plant, p, haven't changed.

What is the equation in point-slope form of a linear equation with a slope of 5 and a point on the line of (-2,3)?
A. y+5= 3(x + 2)
B. y-3 = 5(7+2)
C. y + 3 = 5(x - 2)
D. y + 2 = 5(x – 3)
Answers
Answer:
C. y + 3 = 5(x - 2)
Step-by-step explanation:
If we use the point-slope equation (image attatched), then we do the following:
y2 - y1 = m (x2 - x1)
Where y2 - y1 is difference in the y coordinates, m is the slope, and x2 - x1 is the difference in the x coordinates.
y2 - y1 = m (x2 - x1)
\/
y2 +3 = 5 (x2 - 2)
\/
y + 3 = 5(x - 2) -> C. y + 3 = 5(x - 2)

Answers
9514 1404 393
Answer:
tan(A) = 7/24sin(A) = 7/25cos(A) = 24/25Step-by-step explanation:
The mnemonic SOH CAH TOA can help you remember the trig ratios:
Sin = Opposite/Hypotenuse
Cos = Adjacent/Hypotenuse
Tan = Opposite/Adjacent
With respect to angle A, the sides are Adjacent = 24; Opposite = 7, Hypotenuse = 25. Then the desired trig ratios are ...
tan(A) = 7/24
sin(A) = 7/25
cos(A) = 24/25

Consider the function F(x)= x³ +½x² −2x +3. Use calc and algebra to find any and all stationary points on the graph of the function.Precalc need help ASAP
Solution:
the above function has more than one root or more than one solution. The derivative of the function represents the slope of the tangent line to the curve
F(x)= x³ +½x² −2x +3, F'(x) = 3(x3-1)+(1/2)(2)(x2-1)-2(x1-1)+0
F'(x)=3x2+x-2 is the slope of the tangent line
setting the slope =0 and solving the quadratic equations, you find all the
critical points of interest
3x2+x-2=0, solve by factoring (3x-2)(x+1)=0, then 3x-2=0, x= 2/3
and x+1=0, x=-1 substituting these values of x in the original equation
you get the corresponding values of F(x) such that;
F(x)= x³ +½x² −2x +3, F(x)=(2/3)3+1/2(2/3)2-2(2/3)+3
= 8/27+4/18-4/3+3 = 8/27+2/9-4/3+3/1 = 59/27 and the first point is
(2/3, 59/27)
F(x)= x³ +½x² −2x +3, F(x)=(-1)3+1/2(-1)2-2(-1)+3
= -1+1/2+2+3 = 9/2 and the 2nd point is ( -1, 9/2)
these two points represents points where the slope of the tangent line to the curve is 0 and could be either maximum or minimum points
You can also find the y intercepts where x = 0 F(x)= x³ +½x² −2x +3, setting x = 0, y= F(x)=3 and the point ( 0,3) is a y intercept setting y = 0, then x intercepts can be found upon solving the equation x³ +½x² −2x +3 =0

What integer represents his change in depth
for each minute?
A. 52 feet per minute
B. 44 feet per minute
C. -12 feet
per
minute
D. -48 feet per minute
Answers
Answer:
C. -12 feet per minute
Step-by-step explanation:
This question is really just asking for the slope of this situation. So the best way to find the answer is to find the change in y over the change in x. In this case, y is the depth and x is the time. So, it would be -48/4 because the diver went down 48 feet when 4 minutes passed. Then, simply divide, -48/4, which equals -12 feet/1 minute.

Angie has 12 3/4 yards of fabric to make Halloween costumes. Each fabric costume requires 7/8 yards of fabric. How many costumes can Auntie make?
Answers
Since Angie has 12 3/4 yards of fabric and all and each costume requires 7/8 yards, you can divide 12 3/4 by 7/8.
12 3/4 ÷ 7/8
= 51/4 ÷ 7/8
= 51/4 • 8/7 (remember that dividing by a fraction is the same thing as multiplying by it’s reciprocal)
= 51/1 • 2/7 (after simplifying)
= 102/7
= 14 4/7
Angie can make 14 costumes. She cannot make the 15th one because she’ll run short of fabric.
Calculate the population variance of a population with data of {-3, - 5, 8, 11, 13}.

54.56
68.2
Answers
Answer:
Step-by-step explanation:
First find the airithmatic mean
(-3-5+8+11+13)/5= 4.8
[tex]\frac{(-3-4.8)^2+(-5-4.8)^2+(8-4.8)^2+(11-4.8)^2+(13-4.8)^2}{5}= 54.56[/tex]
The variance of this population data set is 69.45.
How to find the variance of the set of data?To find the variance of the set of data we first need to calculate the mean of the set.
mean = sum of each element / number of elements
mean = (-3 -5 + 8 + 11 + 13)/5 = 3.8
Now, using the formula for variance
s² = (X - mean)²/ (n- 1)
s² = (-3 - 3.8)² + (-5 - 3.8)² + (8 - 3.8)² + (11 - 3.8)² + (13 - 3.8)² / (5- 1)
s² = 46.24 + 77.44 + 17.64 + 51.84 + 84.64 / 4
s² = 277.8/4
s² = 69.45
Hence, the variance of the data is 69.45.

In quadrant 3
sinθ < 0 and tanθ > 0 , then
sinθ = [tex]\frac{opposite}{hypotenuse}[/tex] = - [tex]\frac{12}{13}[/tex] and
cscθ = [tex]\frac{1}{sin0}[/tex] = [tex]\frac{1}{-\frac{12}{13} }[/tex] = - [tex]\frac{13}{12}[/tex]
