Answer:

1. n=-10 2.n=-4

Step-by-step explanation:

1. Step 1: Simplify both sides of the equation.

4(n+9)=−4

(4)(n)+(4)(9)=−4(Distribute)

4n+36=−4

Step 2: Subtract 36 from both sides.

4n+36−36=−4−36

4n=−40

Step 3: Divide both sides by 4.

\frac{4n}{4} =\frac{-40}{4}

n=-10

Step 1: Simplify both sides of the equation.

−2(3n−5)=34

(−2)(3n)+(−2)(−5)=34(Distribute)

−6n+10=34

Step 2: Subtract 10 from both sides.

−6n+10−10=34−10

−6n=24

Step 3: Divide both sides by -6.

\frac{-6n}{6}= \frac{24}{-6}

n=-4

Hope this helps :)

A triangle is shown below what is the measure of
Paha777 [63]

Answer:

70 Degrees

Step-by-step explanation:

All triangles add up to 180 degrees so add 44+26=70 180-70= 110 so remaining angle is 110. A straight line is 180 degrees so using the remaining angle of the blue triangle we find that 180-110=70 so B is 70 degrees.

What is the value of b that makes the lines, given by 3x-y=4 and 2y+4bx=1, perpendicular?
USPshnik [31]

b = 1/6

Explanation:

3x-y=4 ...1st equation

Rewriting in slope- intercept form:

y = 3x - 4

2y+4bx=1

Rewriting in slope- intercept form:

2y = -4bx + 1

y = -4bx/2 + 1/2

Equation of line: y = mx + c

where m = slope, c = intercept

For a line to be perpendicular to another, the slope of one will be the negative reciprocal of the slope of another.

Slope of the 1st equation = 3

m = 3

reciprocal of 3 = 1/3

negative reciprocal of 3 = -1/3

Slope of the 2nd equation = -4b/2

we equate both slope:

negative reciprocal of 3 = -4b/2

-1/3 = -4b/2

cross multiply:

-1(2) = 3(-4b)

-2 = -12b

Divide both sides by -12:

-2/-12 = -12b/-12

b = 1/6

Hence, the value of b that makes the lines perpendicular is 1/6
