Graph the equation- 2x-3y=43

1 answer:

5 0

You'd have to turn it into slope-intercept form. To do this you subtract 2x from both sides then divide -3 on both sides:

2x - 3y = 43

2x - 3y -2x = 43 -2x

-3y = -2x + 43

-3y/-3 = -2x/-3 + 43/-3

y = 2/3x - 43/3

The y intercept would be - 43/3 and the slope is 2/3.

The distance around a circular dance hall room is 135 feet. What is the longest distance around the dance hall?

Naya [18.7K]

Answer: 43feet

Step-by-step explanation:

Perimeter= 135 feet

Since perimeter= 2πr

135 = 2πr

Recall that π = 3.14

135 = 2 × 3.14 × r

135 = 6.28 × r

135 = 6.28r

r = 135/6.28

r = 21.5

d = 2r

d = 2 × 21.5

d = 43 feet

Which is bigger, one fourth of 16 or one third of 24? Explain and show work please.

adoni [48]

1/4 x 16
= 16 ÷ 4
= 4

1/3 x 24
= 24 ÷ 3
= 8

8 is greater than 4, so one third of 24 is bigger than one fourth of 16

Given that √5 ≈ 2.2360679775 and ???? ≈ 3.1415926535, find the sum √5 + ???? to an accuracy of 10−8 without using a calculator.

muminat

Answer:

√5 + π = 537766063.1 × $10^{-8}$

Step-by-step explanation:

given data

√5 ≈ 2.2360679775

π ≈ 3.1415926535

to find out

√5 + π

solution

√5 + π = 2.2360679775 + 3.1415926535

√5 + π = 5.3776606310

√5 + π = 5.3776606310 × $\frac{10^{-8}}{10^{-8}}$

√5 + π = 537766063.1 × $10^{-8}$

Which is the value of (−5) g ( - 5 ) if ()=3.4−8 g ( x ) = 3 . 4 x - 8 ?

quester [9]

For this case we have the following function:

$g (x) = 3.4x - 8$

We must find the value of the function for $x = -5$

We have then:

$g (-5) = 3.4 (-5) - 8$

Rewriting the function we have:

$g (-5) = -17 - 8\\g (-5) = -25$

Answer:

The value of g (-5) is given by:

$g (-5) = -25$
