Answer:

x-intercept is at (-14,0)

Step-by-step explanation:

First find the equation of the straight line in slope-intercept form using the given points

Equation of a straight line in slope-intercept form

y = mx + b    (1)

where m = slope and b is the y-intercept

Slope can be calculated using any two of the three given points, computing their y difference values and dividing by the corresponding difference in x values

If (x₁, y₁) and (x₂, y₂) are two points on the line, slope

m = \frac{y_2-y_1}{x_2-x_1}

Choosing the points (-74, 18) and (-54, 12)

m = \frac{18-12}{-74-(-54) }=  \frac{6}{-74+54} = \frac{-6}{20} = -0.3

Plugging value of m in equation (1)

y = -0.300x + b   (2)

To find the value of b, the y-intercept, we can select any of the points, plug in x and y values and solve for b

Let's choose the first point which we have not used

We have x = -94, y = 24

Plugging these values into equation (2)

24 = -0.3(-94) + b

24 = 28.2 + b

b = 14-28.2 = -4.2

Therefore b = -4.2 and the equation of the line is

y = -0.3x - 4.2

The x intercept can be found by setting y = 0 in the above equation and solving for x

Setting y = 0 we get

0 = -0.3x -4.2

0.3x = -4.2

x = (-4.2)/0.3 = -14

Therefore x-intercept is at (-14,0)

4x−2y=14 y=12x−1 solve by substitution
Tatiana [17]

Answer:

x= -3/5

Step-by-step explanation:

4x-2y=14

y=12x-1

4x-2(12x-1)=14

4x-24x+2=14

4x-24x=12

-20x=12

×= -12/20

x= -3/5

Fill in the missing numbers to complete the linear equation that gives the rule for this table.
irakobra [83]

The value of the missing number to complete the linear equation are 31 and -10 respectively.

What is Algebraic expression ?

Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.

Here the given tables shows the coordinates of the linear equation and to find the equation  we consider any two points let suppose the those two points be (0,-10) and (1,21).

Now using slope formula to find the slope of line m :

m = (y₂-y₁)/ (x₂-x₁)

m = (21-(-10))/(1-0)

m = 31

Let us first find the equation of the line using point-slope equation of line :

(y-y₁) = m(x-x₁)

Substituting all the values in above equation to get the equation of line :

(y-(-10)) = 31(x-0)

(y+10) = 31x

y = 31x - 10

Therefore, the value of the missing number to complete the linear equation are 31 and -10 respectively.

jasmine took a cab home from her office. the cab charged a flat fee of $4, plus $2 per mile. Jasmine paid $32 for the trip. How
kykrilka [37]
Well if the flat fee is $4 and you pay $2 per mile and she spent a total of $32, the answer would have to be 14 miles

what is the 18th term in an arithmetic sequence with the first term equal to 6 and the constant difference equalto 17?​
Vinil7 [7]

Answer: The 18th term is 295.

Step-by-step explanation: By using the arithmetic sequence formula:

a(n): nth term

a(1): first term

n: term position

d: common/constant difference

a(n) = a(1) + (n - 1)d

You should get an equation of a(n) = 6+(18 - 1)17. By following the order of operations, you should receive an 18th term of 295.
