Answer:

M = -2

Step-by-step explanation:

-17 + 62 = -5 (3M - 3)    Distribute -5 into the parentheses and combine like terms

45 = -15M + 15 Subtract 15 from both sides

30 = -15M    Divide 15 from both sides

M = -2

When a number is increased by 8.2%, the result is 106. What is the original number to the nearest tenth?
ruslelena [56]

Answer:

Step-by-step explanation:

Let the original number = x

x+\frac{8.2}{100}*x=106\\\\x+0.082x=106\\\\1.082x=106\\\\x=\frac{106}{1.082}\\\\x=\frac{106*1000}{1.082*1000}\\\\x=\frac{106000}{1082}\\\\x=97.96\\\\

x=98.0

x=98

Find the equation of a line that passes through the points (1,2) and (5,6). Leave your answer in the form y=mx+c
Ainat [17]

Answer:

y=x+1

Step-by-step explanation:

first find the slope using the two coordinates:

use the slope formula- m=y^2-y^1/x^2-x^1

6-2/5-1

=4/4

=1

y=mx+b

now plug in one of the coordinates, and the slope we just found into the slope intercept formula

2=1(1)+b

2=1+b

subtract 1 from both sides

1=b

1=b; m=1,

y=x+1

Please help me, ill give brainliest
Rzqust [24]

Answer:

m∠RST = 20

Step-by-step explanation:

Sine the line SP bisects ∠RST, we know that the two angles that were formed are equal.  Set ∠RSP equal to ∠PST.

∠RSP = ∠PST

3x - 2 = 9x - 26

(3x - 2) + 2 = (9x - 26) + 2

3x = 9x - 24

3x - 9x = (9x - 24) - 9x

-6x = -24

(-6x)/-6 = -24/-6

x = 4

Now that you know the value of x, add ∠RSP and ∠PST.  This will give you m∠RST.

m∠RST = (3x - 2) + (9x - 26)

m∠RST = 3x - 2 + 9x - 26

m∠RST = 12x - 2 - 26

m∠RST = 12x - 28

m∠RST = 12(4) - 28

m∠RST = 48 - 28

m∠RST = 20
