Answer:
Step-by-step explanation:
If the length of a bridge on a map is 1 cm,then the actual length = 40,000
If the length of a bridge on a map is 1.5 cm,then the actual length= 1.5 * 40000
= 60000.0 = 60,000 m
Answer: It should be -(x - 2)
Step-by-step explanation:
the reason is this right here
y - y1 = m(x - x1)
y1 = 4
x1 = 2
m = -1
y - 4 = -(x - 2)
Answer:
30 girls
Step-by-step explanation:
10 x 2= 20
15x2=30
For every 10 boys there are 15 girls. since 20 is just 10 multiplied by 2 you can multiply 15 by 2
Answer:
<h2>
the first ordered pair is (-2, -2)</h2><h2>
the second ordered pair is (4,0)</h2>
Step-by-step explanation:
to find the missing values, plug in the given values into the equation:
x-3y=4
the first ordered pair:
we are given a y-value (-2), so lets plug it into the equation:
x-3*(-2)=4
now solve for the missing value:
x+6=4
x=4-6
x=-2
now plug in both x and y and check if the equation is true:
(-2)-3*(-2)=4
-2+6=4
6-2=4
4=4
the first ordered pair is (-2, -2)
the second ordered pair:
we are given a x-value (4), so lets plug it into the equation:
(4)-3y=4
now solve for the missing value:
-3y=4-4
-3y=0
y=0/-3
y=0
now plug in both x and y and check if the equation is true:
(4)-3*(0)=4
4-0=4
4=4
the second ordered pair is (4,0)
