1 answer:

6 0

Just find the points on the graph and it will create a line. For (-2,1) on the graph go left two time and up one. For (4,-2) go right four times and down two times. Then connect the dots. Hope this helps!

1) Find an equation of the line that passes through thr pair of points (-5,-9) and (2,-7).

Yuki888 [10]

1: Assuming this line is linear, the first thing to do is find the slope.
The slope formula is $m=\frac{ y_{2} - y_{1} }{ x_{2} - x_{1} }$ , so in this case, it is $m=\frac{ (-7) - (-9) }{ 2 - (-5) }$ , which comes to $\frac{2}{7}$ . Then, use your slope and one of the points given to write the point-slope formula of the linear equation, and then written in standard form:
y= $\frac{2}{7}$ x- $\frac{53}{7}$ .

2. Use the same process as in question 1 to find:
y=-7x+11

100 milk cartons were put out for breakfast, After breakfast, there were 40 milk cartons left. What is the ratio of milk cartons

Sveta_85 [38]

Answer:

The ratio of milk cartons drunk to total milk cartons put out= 3 : 5

Step-by-step explanation:

Total milk cartons put out for breakfast=100

Milk cartons left after breakfast=40

Total milk cartons drunk during breakfast = Total milk cartons put out for breakfast - Milk cartons left after breakfast

=100 - 40

=60

Total milk cartons drunk during breakfast = 60

What is the ratio of milk cartons drunk to total milk cartons put out?

Total milk cartons drunk during breakfast : Total milk cartons put out for breakfast

= 60 : 100

=3 : 5

The ratio of milk cartons drunk to total milk cartons put out= 3 : 5

there are 76 birdhouses, if 4 birdhouses are occupied, how much percent of the birdhouses are occupied?

Llana [10]

To find the percent of the birdhouses occupied, divide the number of occupied birdhouses by how many birdhouses there are in total:

$4 \div 76 = 0.0526$

Convert this decimal into a percentage by multiplying by 100:

$0.0526 \times 100 = 5.26$

5.26% of the birdhouses are occupied.

The base of a triangle is 9/4 times of its height. If the area of triangle is 144 cm2. Find the height and the base.

Mazyrski [523]

Step-by-step explanation:

Given that the base of triangle is 9/4 times of its height . And area is 144 cm² . Let the height be h , then its base be 9h/4 .

• According to Question :-

$\tt\to Area_{(\triangle)}=\dfrac{base\times height}{2}\\\\\tt\to 144cm^2 = \dfrac{9h\times h}{4\times 2 } \\\\\tt\to h^2 =\dfrac{12\times 12 \times 2 \times 2 }{3\times 3 }\\\\\tt\to h =\sqrt{\dfrac{12\times 12 \times 2 \times 2 }{3\times 3 }}\\\\\tt\to h =\dfrac{(12)(2)}{3} \\\\\tt\to \boxed{\orange{\tt h = 8 cm }}$

Therefore ,

Height = h = 8cm .
Base ,= 9h/4 = 18cm .
