Can someone help me please

it might be positive slope

Step-by-step explanation:

10

Step-by-step explanation:

okay so the equation would be y=10x+15

x is the # of hours and y is the total cost

this linear equation is in the form y=mx+b

in these equations, the value of m is the slope

since our m would be 10, the slope is 10

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
