4<br>-5a+b=8<br>7a +9b = -32<br>I need to use substitution for this one. Help?

Sauron [17]

Answer:

Step-by-step explanation:

$\left\{\begin{array}{ccc}-5a+b=8&\text{add}\ 5a\ \text{to both sides}\\7a+9b=-32\end{array}\right\\\\\left\{\begin{array}{ccc}b=5a+8&(1)\\7a+9b=-32&(2)\end{array}\right\\\\\text{Substitute (1) to (2):}\\\\7a+9(5a+8)=-32\qquad\text{use the distributive property}\\\\7a+(9)(5a)+(9)(8)=-32\\\\7a+45a+72=-32\qquad\text{subtract 72 from both sides}\\\\52a=-104\qquad\text{divide both sides by 52}\\\\\boxed{a=-2}\\\\\text{Put the value of}\ a\ \text{to (1):}\\\\b=5(-2)+8\\\\b=-10+8\\\\\boxed{b=-2}$

Think about the function f(x) = 3 - 2x.<br><br> What does the notation f(0) mean?

dlinn [17]

In order to find this you have to replace any x with zero therefore we will have
3 - (2*0) => 3-0 = 3
so the answer is 3

Here we go ~

take value of pi = 3

r = radius = 5 cm

h = height = 9 cm

Let's calculate volume of Cylinder ~

$\qquad \sf \dashrightarrow \:v = \pi {r}^{2} h$

$\qquad \sf \dashrightarrow \:v = 3 \times {5}^{2} \times 9$

$\qquad \sf \dashrightarrow \:v = 3\times25 \times 9$

$\qquad \sf \dashrightarrow \:v = 75 \times 9$

$\qquad \sf \dashrightarrow \:v =67 5 \: \: cm {}^{3}$

That's all, ask me if you have any queries ~

You want to wire a square piece of land that has an area of 196 square meters. How many meters of wire is needed to fence the

d1i1m1o1n [39]

Answer:

Step-by-step explanatio

We look for the side

To know how many meters of wire we must first know the measurement of the sides of the land. They give us a land area of 196 m², as the land is square, we can take the square root of the area and we have the dimension of the sides

L = √196 m²

L = 14 m

Once the value of the side of the land is obtained, we proceed to determine the perimeter of the land, which will give us the size of the wire to fence

P = L + L + L + L

P = 14m + 14m + 14m + 14m

P = 56 m (this is the dimension of the wire for one turn of the ground)

They ask us for 5 laps.

56m * 5 = 280m

it takes 280 m
