djverab [1.8K]

Answer:

y=-3x+4

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-8-7)/(4-(-1))

m=-15/(4+1)

m=-15/5

m=-3

y-y1=m(x-x1)

y-7=-3(x-(-1))

y-7=-3(x+1)

y=-3x-3+7

y=-3x+4

The students at Norton School were asked to name their favorite type of pet. Of the 430ilar results, about students surveyed, 25

elena-s [515]

Answer: 60

Step-by-step explanation:

From the question, we are informed that 430 students were surveyed and 258 said that their favorite type of pet was a dog. The fraction/decimal of those that chose dog as their favorite pet will be:

= 258/430

= 3/5

= 0.6

Suppose that only 100 students were surveyed, the number of students that would say that a dog is their favorite types of pet will be:

= 0.6 × 100

= 60

Solve 9(t-7)=u for t Show all solving steps.

Gwar [14]

$\begin{gathered}\\ \sf\longmapsto 9(t-7)=u\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto 9t-63=u\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto 9t=u+63\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto \frac{9t}{9}=\frac{u+63}{9}\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto t=\frac{u+63}{9} \end{gathered}$

$\begin{gathered}\\ \sf\longmapsto t=\frac{u}{9}+7\end{gathered}$
