Answer:

y intercept = -5

x intercept = 4

Step-by-step explanation:

f(x) can be substituted with y for this question.

y = 5/4x - 5

the way to solve for x intercept is to set y to 0 and solve for x

0 = 5/4x - 5

5 = 5/4x

multiply by four on both sides

20 = 5x

divide by five on both sides

4 = x

the way to solve for the y intercept is to set x to 0 and solve for y

y = 5/4(0) - 5

y = -5

you can then graph the points (4,0) and (0,-5) to create the line for the function.

Make x the subject of y(x+z)=3z(x+y)

nirvana33 [79]

First distribute
a(b+c)=ab+ac
y(x+z)=yx+yz

3z(x+y)=3zx+3zy

so now we have
yx+yz=3zx+3zy
make all x's on one side
subtract 3zy frm btohs ides
yx-3zx+yz=3zy
subtract yz frmo both sides
yx-3zx=3zy-yz
undistribute the x on the left side
x(y-3z)=2zy
divide both sides by (y-3z)
x= $\frac{2zy}{y-3z}$

Answer:

${3}^{2}$

Step-by-step explanation:

$3^{ - 6} \times (3^4 \div 3^0)^2$

$\frac{1}{ {3}^{6} } \times ( {3}^{4} \div {3}^{0} {)}^{2}$

$\frac{1}{729} \times ( {3}^{4} \div {3}^{0} {)}^{2}$

$\frac{1}{729} \times ( {3}^{4} {)}^{2}$

$\frac{1}{729} \times 6561$

$\frac{1}{729} \times (729(9))$
