Answer:
5
Step-by-step explanation:
slope = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]
The second y point is 16 and the first is -4, so:
(16) - (-4)
Which can be written as 16 + 4 because a double negative makes a positive. Do the same for the x points, -7 and -3:
(-7) - (-3)
(-7) + (3)
Now solve both of them:
16 + 4 = 20
(-7) + 3 = -4
Remember, the slope formula is y over x, so we still need to put it into the fraction form:
[tex]\frac{20}{-4}[/tex]
You can reduce this to [tex]-\frac{5}{1}[/tex], or 5.
The slope of the line will be "-5".
Given points are:
[tex](x_1,y_1) = (-3,-4)[/tex][tex](x_2,y_2) = (-7,16)[/tex]As we know the formula,
→ Slope, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
By substituting the values, we get
[tex]= \frac{16-(-4)}{-7-(-3)}[/tex]
[tex]= \frac{16+4}{-7+3}[/tex]
[tex]= -\frac{20}{4}[/tex]
[tex]= -5[/tex]
Thus the above answer is correct.

ayden has 5.5 gallons of gasoline in his suv’s fuel tank before it starts refilling. the capacity of the fuel tank in aydens suv is 21 gallons. what is an equation that relates the amount of gasoline ayden purchased, p, in gallons and the amount of gasoline in the fuel tank, A after the purchase? what values of P could be viable solutions?
Answer:
[tex]0<p\leq15.5[/tex]
Step-by-step explanation:
Amount of gasoline in the tank is 5.5 gallons
21 gallons is the capacity of the fuel tank in the car
A is the amount of gasoline in the fuel tank after purchase which will be less than or equal to 21 gallons.
So the equation will be
[tex]5.5+p\leq A\\\Rightarrow 5.5+p\leq 21\\\Rightarrow p\leq 21-5.5\\\Rightarrow p\leq 15.5[/tex]
So, the value of p is in the range of [tex](0,15.5][/tex] or [tex]0<p\leq15.5[/tex].

Find the zero of the function.
g(x) = x2 + 22x + 121
The zero of the function is x=
Answer:
x = -11
Step-by-step explanation:
To find the zero of this function, factor the equation:
g(x) = [tex]x^{2} +22x+121[/tex]
g(x) = (x + 11) (x + 11)
g(x) = [tex](x+11)^{2}[/tex]
The zeros of a function are the values of x that will make g(x) equal 0. So, the zero of this function is -11, because -11 + 11 = 0. So, x = -11.

What is the width of a rectangle with length 25" in area 375" squared?
Answer:
Width, W = 15 inches
Step-by-step explanation:
Let L = length of the rectangle
Let W = width of the rectangle
Given the following data;
Area, A of rectangle = 375 in²
Length, L of rectangle = 25 in
*To find the width of the rectangle*
We know that the area of a rectangle is given by the formula;
[tex] Area = length * width [/tex]
[tex] A = L * W[/tex]
Making "W" the subject of formula;
[tex] W = \frac {A}{L} [/tex]
Substituting into the equation, we have;
[tex] W = \frac {375}{25} [/tex]
W = 15 in
Therefore, the width of the rectangle is 15 inches.
A large water reservoir can be well modeled with a hemisphere whose radius is 630 meters. Given the volume formula for a sphere, 4 3 3 V r , find the volume of water the reservoir can hold. Show your substitution. Express your answer in scientific notation with two decimal places of accuracy.
Answer:
[tex]V=5.23\times 10^8\ m^3[/tex]
Step-by-step explanation:
A large water reservoir can be well modeled with a hemisphere whose radius is 630 meters.
The volume of a hemisphere is given by :
[tex]V=\dfrac{2}{3}\pi r^3[/tex]
Substitute r = 630 m in the above formula
[tex]V=\dfrac{2}{3}\pi \times (630)^3\\\\=5.23\times 10^8\ m^3[/tex]
So, the water reservoir can hold [tex]5.23\times 10^8\ m^3[/tex] of water.

Deandra spent $14.00 of the $20.00 in her wallet. What decimal is equivalent to the fraction of the $20.00 Deandra spent? $14.00 of the $20.00 means 14 over 20.
Answer:
0.7
Step-by-step explanation:
Deandra spent $14.00 of the $20.00 in her wallet.
We write this expression above in a fraction format
= $14.00/$20.00
= 14/20
The decimal is equivalent to the fraction of the $20.00 Deandra spent is:
= 14/20
Dividing both the numerator and denominator by 2
= 7/10
= 0.7
The coordinates of the 3 of the vértices of a parallelogram are (-7, 3), (-6, 1), and (-4, 5). What is the equation for the line containing the side opposite the side containing the first two vertices?
We know, opposite sides are parallelogram is parallel, therefore slopes are equal.
Slope of line one :
[tex]m=\dfrac{-7-(-6)}{3-1}\\\\m =\dfrac{-1}{2}\\\\m= -0.5[/tex]
So, equation of other line passing through (-4,5) and have slope of -0.5 is :
y-5 = -0.5( x-(-4))
y-5 = -0.5x - 2
y + 1/2x = 3
2y + x = 6
Therefore, equation of line containing the (-4, 5) is 2y + x = 6.
Hence, this is the required solution.
