Answer:

You can't answer this question since there is no picture. Remember though the any 2 angles that make 180 degrees or resembles a line is 180 degrees.

Answer: 10 times 8 and 8 times 10

Step-by-step explanation:

those are the first in the multiplication table that have the same digits

Answer:

D

Step-by-step explanation:

The square root of 36 is 6 and the square root of 81 is 9 so that cancels out the answers C and B then there is a subtraction symbol in the original equation so there has to be one in the answer which cancels our A and leaves you with the final answer D.

Answer:

Tree farm A mean = 8

Tree farm B mean = 8

Tree farm B

Step-by-step explanation:

Average the numbers

Answer:

no solution

Step-by-step explanation:

It's no solution because the first step to do is to subtract 9 from both sides which would give you x=x-18 but now your stuck here because if you subtract x from both sides then you wont have an x so this equation has no solution

Answer:

No solution

Step-by-step explanation:

Answer:

The answer is

[tex] \huge x > - 8[/tex]

Step-by-step explanation:

[tex]5 − (x + 5) > −2(x + 4)[/tex]

First of all expand the terms in the bracket

That's

[tex]5 - x - 5 > - 2x - 8 \\ - x > - 2x - 8[/tex]

Add 2x to both sides

[tex] - x + 2x > 2x - 2x - 8 \\ x > - 8[/tex]

We have the final answer as

[tex]x > - 8 [/tex]

Hope this helps you

Answer:

x > -8

Step-by-step explanation:

5 − (x + 5) > −2(x + 4)

Simplify both sides first:

5 - x - 5 > -2x - 8

-x > -2x -8

Now isolate the variable:

-x > -2x -8

+2x  +2x

x > -8

Answer:

C on edge

Step-by-step explanation:

The solution is, (0.9273 +2nπ,0), where n is any integer, are the x-intercepts of the graph of the function y=6tan (x/2)-3.

Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable.

here, we have,

given that,

the function is,

y=6tan (x/2)-3

we know that,

the x-intercepts of the graph of the function, we put y = 0

so, we get,

6tan (x/2)-3 = 0

or, tan (x/2) = 3/6

or, tan (x/2) = 1/2

or, x/2 = 0.4636

The period of tangent is π, so we have,

x/2 = 0.4636 + nπ

or, x =  (0.9273 +2nπ)

Hence, The solution is, (0.9273 +2nπ,0), where n is any integer, are the x-intercepts of the graph of the function y=6tan (x/2)-3.

Answer:

The equation of the line is y = [tex]\frac{4}{3}[/tex] x + 2

Step-by-step explanation:

The form of the equation that passes through two points (x1, y1) and (x2, y2) is y = m x + b, where

Let us solve the question:

∵ The line passes through the points (-3, -2) and (3, 6)

∴ x1 = -3 and x2 = 3

∴ y1 = -2 and y2 = 6

→ Use the rule of m to find it

∵ [tex]m=\frac{6-(-2)}{3-(-3)}=\frac{6+2}{3+3}=\frac{8}{6}[/tex]

→ Simplify it by dividing up and down by 2

∴ m = [tex]\frac{4}{3}[/tex]

→ Substitute its value in the form of the equation above

∴ y = [tex]\frac{4}{3}[/tex] x + b

→ To find b substitute x and y by x1 and y1

∴ -2 = [tex]\frac{4}{3}[/tex] (-3) + b

∴ -2 = -4 + b

→ Add 4 to both sides

∴ -2 + 4 = -4 + 4 + b

∴ 2 = b

→ Substitute it in the form of the equation

∴ y = [tex]\frac{4}{3}[/tex] x + 2

∴ The equation of the line is y = [tex]\frac{4}{3}[/tex] x + 2

Answer:

s>2

Step-by-step explanation:

2 + 4s >10

First, subtract 2 on both sides.

2 + 4s >10

-2         -2

4s>8

Divide by 4 on both sides to isolate x.

4s>8

/4  /4

s>2

Step-by-step explanation:

Answer:   x-intercept = 7/5 = 1.40000

 y-intercept = -7/4 = -1.75000

Step-by-step explanation: Solve   4y-5x+7  = 0

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line  4y-5x+7  = 0 and calculate its properties

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is -1.750 and for x=2.000, the value of y is 0.750. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 0.750 - (-1.750) = 2.500 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

   Slope     =  2.500/2.000 =  1.250

Answer:

a: y=-1/2x-3/2

b: y= -4x+2

Step-by-step explanation:

80% of 15 is 12

15-12=3

Answer: 9, 18, 21, and 23 respectively

Step-by-step explanation:

To solve any problem like this, you want to assign a variable to each child because you dont know their age. So lets write an equation and assign variables to these children.

r = first child (youngest)

x = second child

y = third child

z = fourth child (oldest)

We know that r + x + y + z = 71

We also are given info on the comparisons of their ages.

r = r

x = 2r (2 times the youngest)

y = 12 + r (12 more than the youngest)

z = 3r - 4 (4 less than 3 times the youngest)

That was the easy part tbh, now we have to solve for 'r'. We can see that all the ages are a function of the same variable (r), and we know the sum of them is equal to 71. So lets solve for r and then plug that r value into each equation we just derived.

Child #1 (youngest)

[tex]r+2r+(12+r)+(3r-4)=71\\3r+12+r+3r-4=71\\7r+12-4=71\\7r+8=71\\7r=63\\r=9yrs[/tex]

Child #2

[tex]x=2*9=18yrs[/tex]

Child #3

[tex]y=12+r=12+9=21yrs[/tex]

Child #4 (oldest)

[tex]z=3r-4=(3*9)-4=27-4=23yrs[/tex]

Fact Check:

[tex]9+18+21+23=71[/tex]

Answer:

the retirement fund would last 12 years

Step-by-step explanation:

first we find the amount of years one will be saving money by subtracting the age one will start saving money from the age one would start using the money.

65 - 25 = 40 years

next will be finding the amount of dollars one would save every year, we do that by multiplying the money one is saving every month by 12 (a year).

12 × 750 = 9,000 dollars per year

then we multiply the amount of money one would save per year by the amount of years one will be saving money in, to find how many dollars one would save in 40 years.

9,000 × 40 = 360,000 dollars in 40 years

-

after that we divide the amount one would have saved by the $2,500 one would use every month to find the amount of months the money would last.

$360,000 ÷ $2,500 = 144 months

to find how many years the money would last, one would divide it by 12, which is the amount of months per year.

144 ÷ 12 = 12

It will last 12 years. So it'll last till he's 77 years old at the rate he's pulling it out.

Step-by-step explanation:

This is why it'll last him 12 years, which he'll be 77 by that time !! I hope this helped !!
