1. Line L mapped onto line M by a dilation centered

Nonamiya [84]

Answer:

$y = 4x - 6$

Step-by-step explanation:

The equation of line L is

$4x - y = 2$

We solve for y to get;

$y = 4x - 2$

This line is mapped onto line M by a dilation centered at the origin with a scale factor of 3.

Line M will also have the same slope as line L.

Only the y-intercept will change.

The y-intercept of L is (0,-2).

The y-intercept of M will be (0,-6) because we multiplied each by 3.

The equation of line M is

$y = 4x - 6$

Question 1 (Essay Worth 10 points) (01.02 MC) Part A: If (26)x = 1, what is the value of x? Explain your answer. (5 points) Part

katen-ka-za [31]

Answer:

See Explanation

Step-by-step explanation:

The question is not clear. However, I will treat the question as:

$(26)x = 1$

$(50)x = 1$

and:

$(2^6)^x = 1$

$(5^0)^x = 1$

Solving: $(26)x = 1$ and $(50)x = 1$

$(26)x = 1$

Divide both sides by 26

$x = \frac{1}{26}$

$(50)x = 1$

Divide both sides by 50

$x = \frac{1}{50}$

Solving $(2^6)^x = 1$ and $(5^0)^x = 1$

$(2^6)^x = 1$

Express 1 as 2^0

$(2^6)^x = 2^0$

Remove bracket

$2^{6x} = 2^0$

Cancel out 2

$6x = 0$

Divide both sides by 6

$x = \frac{0}{6}$

$x = 0$

$(5^0)^x = 1$

Express 1 as 5^0

$(5^0)^x = 5^0$

Cancel out 5^0

$x = 1$

What fraction to i times 2/17 by to get 1

maxonik [38]

Answer:

impossible

Step-by-step explanation:

17 does not match the circumference that 2 gives off so the vibes are different so its a trick question because 17 isn't aloud to be divided by 2

Population of 2,400 increased by 80%

FrozenT [24]

The answer is 2400 + 80% = 4320

Working out 2400 divided by 10= 240

240 = 10%

240 x 8=1920

1920= 80%

1920 + 2400= 4320
