Answer:

Step-by-step explanation:

Because the order of operations stands for parenthesis, exponents, multiply, divide, add, and subtract from left to right.

Examples: 12+9*8÷2

Multiply and divide numbers from left to right.

$\displaystyle 9\times8\div2$

$\displaystyle 9\times8=72$

$\displaystyle 72\div2=36$

$\displaystyle 36+12$

Add numbers from left to right.

$\displaystyle 36+12=48$

$\huge \boxed{48}$ , which is our answer.

Answer:

(0,170) and (60,-70) and (5, 150)

Step-by-step explanation:

To see if a given point is on the line or not, you just have to enter the x value (first value in the parenthesis) and see if the function returns the correct y value (second number in the parenthesis).

f(x) = -4x + 170

(170,0) => -4 (170) + 170 = -680 + 170 = 510. NO, not equal to 0.

(0,170) => -4 (0) + 170 = 0 + 170 = 170. YES

(12, 126) => -4 (12) + 170= -48 + 170= 122. No, not equal to 126.

(50,30) => -4(50) + 170 = -200 + 170 = 130. No, not equal to 30.

(5, 150) => -4(5) + 170 = -20 + 170 = 150. YES

(60,-70) => -4(60) + 170 = -240 + 170 = -70. YES

Jill is standing at the base of her apartment building. She measures the angle of elevation to the top of a nearby tower to be 4

Helga [31]

Answer:

1) From the measure of 40°, you can write:

tan(40°) = 100/x, where x is the base from the building to the tower

⇒x=100/tan(40°) = 119,18 m

2) From the measure of 30°, you can write

tan(30°) = y / 119,18, where y is the height from the roof of Jill's building to the top of the tower.

Then, y = tan(30°) * 119,18 = 68,81 m

3) The height of Jill's building is 100 - 68,81 = 31,19 m

Vanyuwa [196]

An infinite number of solutions means a coincident line...it is the same line
3y = 2x - 9...divide by 3
y = 2/3x - 3...hmm...same line as answer choice b....they are coincident lines and have infinite solutions

9x+14=13x-10 I need the individual steps

kogti [31]

First start by subtracting 9x from both sides and getting 14=4x-10. Then add ten to both sides getting 24=4x. Then divide 24 by 4 and you get x=6
