4 0

Answer:
slope of line is 3
y-intercept of line is -13

Explanation:
The general formula of the linear line is:
y = mx + c
where:
m is the slope of the line
c is the y-intercept

The given line is:
y = 3x - 13

Comparing the given line with the general formula, we would find that:
m (the slope of the line) is 3
c (the y-intercept) is -13

Hope this helps :)

Answer:

3rd option - 14 m²

Step-by-step explanation:

First we know that the square's area will be 2×2 = 4

To calculate the area of a triangle we know the vertical height is 2.5 and the base length is 2 so we can use the formula b×h/2 to give the area of one triangle:

2.5×2 = 5

5÷2 = 2.5

So the area of 1 triangle is 2.5 m²

Since there are 4 triangles we multiply the area of 1 traingle by 4:

2.5×4 = 10

We add the area of the 4 triangles to the area of the square to give our final answer of :

10 + 4 = 14

14 m²

Lisa is 6 centimeters taller than her friend Ian. Ian is 10 centimeters taller than Jim. Every month, their heights increase by

Temka [501]

Lan is 146 centimeters tall now.

Explanation

Let, Lan's current height is $h$ centimeters

As Lisa is 6 centimeters taller than Lan and Lan is 10 centimeters taller than Jim, so Lisa's current height = $(h+6)$ centimeters and Jim's current height = $(h-10)$ centimeters.

Every month, their heights increase by 2 centimeters.

So, after 5 months.....

Lan's height = $h+(2*5)=(h+10)$ centimeters,

Lisa's height = $(h+6)+(2*5)= (h+16)$ centimeters and

Jim's height = $(h-10)+(2*5)= h$ centimeters

Given that, the sum of Ian's and Jim's heights will be 140 centimeters more than Lisa's height in 5 months. So the equation will be....

$(h+10)+h= (h+16)+140\\ \\ 2h+10=h+156\\ \\ 2h-h=156-10\\ \\ h=146$

So, the current height of Lan is 146 centimeters.
