A linear function has a slope of Negative StartFraction 7 Over 9 EndFraction and a y-intercept of 3. How does this function comp

dem82 [27]

It has the same slope and the same y-intercept, that is, option a is the right choice.

A linear function in the slope-intercept is written as y = mx + b, where m represents the slope of the line and b represents the y-intercept.

We are given two linear functions and are asked to compare them.

First linear function:

Slope (m) = -7/9.

y-intercept (b) = 3.

Therefore, the linear function is: y = (-7/9)x + 3.

Second linear function:

Function given: y + 11 = (-7/9)(x - 18)

or, y + 11 = (-7/9)x + (-7/9)(-18)

or, y = (-7/9)x + 14 - 11 = (-7/9)x + 3.

Therefore, slope (m) = (-7/9)

y-intercept (b) = 3.

Therefore, we can say that it has the same slope and the same y-intercept, that is, option a is the right choice.

What would I to the 8th power be?

FromTheMoon [43]

I think it'd be 1 because well all you are doing is multiplying 1, 8 times. That is only if you meant the I to be 1.

432 divided by the different between 279 and 63

Debora [2.8K]

The difference (I'm assuming you meant difference) between 279 and 63 is
279 - 63 = 216
so divide 432 by 216
432 / 216 = 2
so the answer is 2

The value of x is 5/6 and y is 8/5.

Step-by-step explanation:

Given,

12x+15y=34 Eqn 1

-6x+5y=3 Eqn 2

Multiplying Eqn 2 by 2

$2(-6x+5y=3)\\-12x+10y=6\ \ \ Eqn 3$

Adding Eqn 1 and 3

$(12x+15y)+(-12x+10y)=34+6\\12x+15y-12x+10y=40\\25y=40$

Dividing both sides by 25

$\frac{25y}{25}=\frac{40}{25}\\y=\frac{8}{5}$

Putting y= 8/5 in Eqn 1

$12x+15(\frac{8}{5})=34\\12x+3*8=34\\12x+24=34\\12x=34-24\\12x=10$

Dividing both sides by 12

$\frac{12x}{12}=\frac{10}{12}\\x=\frac{5}{6}$

The value of x is 5/6 and y is 8/5.

Student work TRY IT #1 Write each of the following as a rational number. b. 3 c-4

tino4ka555 [31]

Answer:

b. 3 = 3/1

c. -4 = -4/1

Step-by-step explanation:

An integer can be written as a rational number with a denominator of 1. The denominator can be anything else, too, in which case the numerator must be multiplied by that same value.

b. 3 = 3/1 = 6/2 = 27/9

c. -4 = -4/1 = 8/-2 = -12/3
