Answer:
f(-5) = 15
Step-by-step explanation:
f(x)=5x+40
plug in x as -5
f(-5) = 5(-5) + 40
multiply 5 by -5
-25+40
add -25 to 40
15

Answer:
(c) Triangle Z Y X is similar to triangle C B A
Step-by-step explanation:
Triangles are similar when corresponding sides have the same ratio. Corresponding sides will have corresponding end point vertices. The similarity statement lists corresponding vertices in the same order.
__
<h3>corresponding sides</h3>
The side lengths, smallest to largest, for the two triangles are ...
- 3 cm -- ZY
- 6 cm -- YX
- 7 cm -- XZ
And for the other triangle, ...
- 6 cm -- BC
- 12 cm -- AB
- 14 cm -- AC
<h3>corresponding vertices</h3>
The points joining the each side to the next one longer, in order for the two triangles, are ...
Y, X, Z and B, A, C
The vertices corresponding to ZYX in the same order are CBA.
triangle ZYX is similar to triangle CBA
Option B model shows the percent of beads that are blue.
Solution:
Fraction of beads blue = 
To convert it into percent multiply the fraction by 100.


Cancel the common factors, we get
= 20%

This means total number of boxes 100 and shaded in blue color 20.
Therefore option 2 represents
.
Hence option B model shows the percent of beads that are blue.
