Let’s use y as a replacement for a number. You would do 3y-7 since you multiply by three and take away seven.
Answer:
1 and 2 are not congruent; 1 and 3 are congruent; 1 and 4 are congruent; 2 and 3 are not congruent; 2 and 4 are not congruent; 3 and 4 are congruent.
Step-by-step explanation:
From the diagram, we can see that the angle measures and side measures of figures 1, 3 and 4 are the same. This means that these three figures are congruent. Figure 2, however, is not congruent to any of the other 3.

x= -1
f (-1)= 2. (-1)^2
f (-1)= 2.1
f (-1)= 2
Answer:
B
Step-by-step explanation:
575 x 8 = 4600
4600 x 12 = 55200
55200 - 9880 = 45320
Therefore, our answer is B
the equation framed in the form of y=kx is
and , x as a function of y
.
<u>Step-by-step explanation:</u>
Here we have , The amount Lin's sister earns at her part-time job is proportional to the number of hours she works. She earns $9.60 per hour. We need to find an equation in the form y=kx to describe this situation, where x represents the hours she works and y represents the dollars she earns.Is y a function of x . Also , Write an equation describing x as a function of y . Let's find out:
Here , Lin's sister earns $9.60 per hour . Let x represents the hours she works and y represents the dollars she earns . So , According to question following is the equation framed in the form of y=kx :
⇒ 
Yes, y is a function of x , as a straight line with a slope of 9.6
Now , x as a function of y :
⇒ 
⇒ 
Therefore , the equation framed in the form of y=kx is
and , x as a function of y
.
