Answer:

x = 3

Step-by-step explanation:

Find the equation of a line which passes through the point (3, -1) with the gradient M=2÷3​
cluponka [151]

Step-by-step explanation:

Equ of line -

y=mx+c

Using point (3,-1)

3 as x, - 1 as y

M=2/3

Substitute the values of these coordinates

3=2/3(-1) +c - - - - now find for c

c= 3- (-2/3)

c= 3.67

Now with the value of c, put the values back into the equation form .. Assuming we don't have a point to work with

y=2/3x + 3.67

The table shows the height increases in inches, of some of the girls in Gina’s class from last month to this month. What girl ha
shusha [124]

The correct answer is Maxine

Explanation:

One of the easiest ways for knowing if a fraction is greater than another is by converting fractions to decimal numbers. This implies dividing the numerator (top number) by the denominator (bottom number). In the case of fraction, \frac{1}{2} the decimal number is 0.5 considering 1 divided into 2 is equal to 0.5. Now to know if other fractions are greater or smaller, this process needs to be repeated.

Gina: \frac{3}{8} = 0.375  

Maxine: \frac{2}{3} = 0.666

Shari: \frac{2}{4} = 0.5

Vanessa: \frac{3}{12} = 0.25

According to this, the girl with a heigh increased greater than 1/2 inch is Maxine because 0.666 (Maxine heigh increase) is greater than 0.5 (1/2 inch).

  • f(x) = x² -3
  • g(x) = 6x +7
  • h(x) = 3^x

Step-by-step explanation:

f(x) is copied from the problem statement.

g(x) is a symbolic representation of the English wording, using x to represent "a number."

h(x) is the exponential function that corresponds to the geometric sequence in the table. It has a common ratio of 3, and a multiplier of 1 at x=0.
