Answer:

A) -2/5

Step-by-step explanation:

Note that for a slope, the slope of the line is found by using the equation:

slope = (rise/run).

In this case, find two points. For example, i will use:

(0, 2) & (5, 0). (x = 0, y = 2) ; (x = 5, y = 0)

Note that "rise" = y, and "run" = x. Plug in the corresponding numbers for the corresponding points.

(2 - 0)/(0 - 5) = slope

Simplify

(2)/(-5) = slope

-(2/5) is your answer.

Note that it does not matter where the negative sign is placed.

Two common names for streets are FirstFirst Street and MainMain â€‹Street, with 14 comma 86614,866 streets bearing one of these

oksian1 [2.3K]

Answer: There are 7,677 streets named as " First Street" and 7, 189 streets named as "Main Street" .

Step-by-step explanation:

Let x be the number of streets named as First Street .

y be the number of streets named as Main Street.

AS per the given information, we have the following system of equations :

$x+y=14866-------------(1)\\\\x=488+y-------------(2)$

Substitute the value of x from (2) in (1) , we get

$488+y+y=14866\\\\ 2y =14866- 488\\\\ 2y=14378\\\\ y=7189$

Put value of y in (2), we get

$x=488+7189=7677$

Hence , there are 7,677 streets named as " First Street" and 7, 189 streets named as "Main Street" .

Write an equation of a line containing (2, -3) and perpendicular to 3x+4y=14 answer

Sergio039 [100]

Answer:

Step-by-step explanation:

From the condition of perpendicularity, if two lines must be perpendicular to each other, the product of their gradient rather the slope must be equaled to ( -1 ).

Equation of a line ; y = mx+ c, where m1 is the gradient of the line and c us the point of intersection if the line on the y- axis.therefore, the equation

3x + 4y = 14, when re arranged, now becomes, 4y = -3x + 14, divide through by 4, gives, y = -3x/4 + 14.

Therefore, m1, = -3/4 and m2, = 4/3 going by the condition. Since the line passes through the coordinate of (2,3), where x = 2, and y = -3, then, substitute for x and y in y = mx+ c, minding the m2, to find C, therefore,

-3 = 4/3x2 + c. -3 = 8/3 +c

Multiply through by 3 to make it a linear equation,

-9 = 8 + 3c; -9 - 8 = 3c, -17= 3c

c = -17/3.Now substitute for c in the equation ,y = mx+ c, the equation now becomes, y = 4x/3 - 17/3. Therefore the new equation is

3y = -4x - 17.

A building 220 feet casts a 100 foot long shadow. If a person stands at the end of the shadow and looks up to the top of the bui

kaheart [24]

Answer:

65.56°

Step-by-step explanation:

= We solve the above question using the Trigonometric function of Tangent

tan θ = Opposite/Adjacent

Opposite = 220 feet = Height of the building

Adjacent = 100 feet = Length of the shadow

Hence,

tan θ = 220/100

tan θ = 2.2

= arctan(2.2)

= 65.55604522°

Approximately = 65.56°
