Solve this inequality for x: -46 − 8x > 22.
A.
x -8.5
D.
x > 8.5

Answers

Answer 1

Answer:

x < - 8.5

Step-by-step explanation:

Given

- 46 - 8x > 22 ( add 46 to both sides )

- 8x > 68

Divide both sides by - 8, reversing the symbol as a result of dividing by a negative quantity

x < - [tex]\frac{68}{8}[/tex] , that is

x < - 8.5

Answer 2

Answer:

x < - 8.5

I hope this helps

Answer:

B

Step-by-step explanation:

You have given angle x and the hypotenuse you are asked to find the adjacent side of the triangle so you would be using

Cosθ = Adjacent/hypotenuse.

cos49 = adjacent/4

1.32 = adjacent/4

2.62 = adjacent

VX = 2.6

Remember!

Answer:

  y +2 = (1/4)(x +1)

Step-by-step explanation:

The given line is in slope-intercept form:

  y = mx + b

where the slope (m) is -4 and the y-intercept (b) is +13.

For the perpendicular line, we need a slope that is the opposite reciprocal, or ...

  -1/m = -1/(-4) = 1/4

A suitable form for the desired equation is the point-slope form:

  y -k = m(x -h) . . . . . . line with slope m through point (h, k)

For m=1/4 and (h, k) = (-1, -2), the equation of the line is ...

  y +2 = (1/4)(x +1)

Solve for h.
h/10 + 5 = 25
so what’s h ??

Answers

Answer:

h=200

Step-by-step explanation:

h/10+5=25

h/10=20

h=200

h/10 + 5 = 25

Subtract 5 from each side to get h/10 alone.

h/10 + 5 - 5 = 25 - 5

h/10 = 20

Multiply both sides by 10 to get h alone.

h/10 • 10 = 20 • 10

h = 200

h = 200. I hope this helps!

How much of a radioactive kind of antimony will be left after 120 days if you start with 904 grams and the half-life is 60 days?​

Answers

Answer:  226 grams

==========================================

Explanation:

1/2 = 0.5

Every 60 days, the amount cuts in half.

We start with 904 grams and after 60 days, we have 904*0.5 = 452 grams left over.

After another 60 days, we have 452*0.5 = 226 grams left over.

-------------

Alternative Method:

We can apply the half-life formula.

y = a*(0.5)^(x/H)

where,

y = final amount after x daysa = initial amountx = number of days that elapseH = number of days in a half-life

In this case,

a = 904 is the starting amountH = 60 is the number of days until another half-life occurs

When x = 120 days go by, we have....

y = a*(0.5)^(x/H)

y = 904*(0.5)^(x/60)

y = 904*(0.5)^(120/60)

y = 904*(0.5)^(2)

y = 904*(0.25)

y = 226 grams of antimony left over.

This method is preferred over the first method if you have x be some non-multiple of 60, or if x is fairly large.

Solve this system of equations by graphing. First graph the equations, and then type the solution. y=2x+2 y=x–2

Solution:

The equation of a straight line is in the form y = mx + b, where m is the slope of the graph and b is the y intercept (value of y when x = 0). To graph the line, online geogebra graphing calculator was used for plotting the two graphs by writing the equation of the graphs.

After plotting the two graphs, the intersection of the two lines should be traced to get the x coordinate and y coordinate of the point. This point is the solution of the two graph equations, hence:

The solution = (-4, -6)
