Answer:
20 years
Step-by-step explanation:
when the boy is 8 and half his sisters age his sister is 16
four years later the boy will be twelve, so if his sister was 16 four years later she will be 20
Answer:
20 years old
Step-by-step explanation:
Let n represent the age of the boy's sister then...
[tex]8=\frac{1}{2}n[/tex]
Multiply both sides by 2
[tex]n=16[/tex]
When the boy is 12, it will be 4 years from when he is 8 therefore...
16 + 4 = 20 years old

the graph of the function f(x)=mx+b contains the points (-1,3) and (-2,4) find m and b
Answer:
m = -1; b = 2
Step-by-step explanation:
the first step in solving this equation is to find the slope
so we use the equation (y2-y1)/(x2-x1)
so with this the equation is
(4 - 3)/(-2 + 1)
then it would be 1/-1
that is -1
so the function so far is f(x) = -x + b
to find the b you would plug in the coordinates
we can plug in the first set
3 = 1 + b
b = 2
so the m is -1 and the b is 2

O x>6
O x56
O x <6.
O x26
x < 6
This is because there is an open hole at 6, meaning we exclude it from the solution set. Stuff to the left of 6 (ie smaller than 6) is shaded, which is why we go for x < 6
The inequality represented in the given graph is x < 6.
Given is a number line where an inequality is marked.
We have to find the inequality which represents in the number line given.
Here, a graph or a number line where the numbers are marked from 1 to 9 is drawn.
A blue line is drawn prior to the number 6. So the inequality sign is "<".
An open circle is over the number 6. So 6 is not included in the inequality.
So, the required inequality is x < 6.
The correct option is C. x < 6.

2x + 5y= 10; (4,9)
Write answer in slope intercept form.
Answer:
y = 5x - 5/2xy + 79
Step-by-step explanation:
First we need to solve for m which is slope.
Subtract 5y from both sides
2x = 10 - 5y
Then divide each term by 2
2x/2 = 10/2 + -5y/2
Then simplify to the left
x = 10/2 + -5y/2
Then simplify the right side
x = 5 - 5y/2
Next we have to find the value of b using the formula y = mx + b
So
y = (5 - 5y/2) * x + b
y = (5 - 5y/2) * (4) + b
9 = (5 - 5(9)/2) * (4) + b
Rewrite
(5 - 5(9)/2) * 4 + b = 9
Simplify more
Multiply 5 by 9
(5 - 45/2) * 4 + b = 9
Multiply by 2/2 to write 5 as a fraction
5 * 2/2 - 45/2) * 4 + b = 9
Then combine 5 and 2/2
(5 * 2/2 - 45/2) * 4 + b = 9
Combine the numerator over the denom
5 * 2 - 45/2 * 4 + b = 9
Simplify the numerator
-35/2 * 4 + b = 9
Cancel the common factor of 2
-35 * 2 + b = 9
Multiply
-70 + b = 9
Move the terms without b to the right side
b = 9 + 70 > b = 79
Now we substitute all the values into y = mx + b
y = 5x - 5/2xy + 79
Find the area of the shaded region.
Solve each equation for y. Then find the value of y for each value of x.

A room is 14 yards by 18 yards. Find the cost to carpet this room if carpet costs $2.30 per square yard
Answer:
$579.60
Step-by-step explanation:
First, we need to find the area of the (floor) of the room.
Area = Length * Width
We can plug in the given values into the equation.
Area = 14 yd * 18 yd
Area = 252 yd²
We can set up a conversion factor to see how much it costs to carpet the room...
[tex]\frac{\$2.30}{1 \ yard^2}*252 \ yards^2[/tex]
Cancel out the yd²...
$2.30*252=$579.60

When a triangle is cut by a line parallel to its base, the resulting two triangles are similar. That means corresponding sides are proportional (their ratios are equal).
There are several ways the ratios can be written, but I like to choose one that has the variable in the numerator. Here's the proportion and its solution.
[tex]\dfrac{x+5}{16}=\dfrac{30}{20}\\\\x+5=24\qquad\text{multiply both sides by 16}\\\\x=19\qquad\text{subtract 5 from both sides}[/tex]

Additional comment
Technically, the corresponding sides of the triangles would be ...
entire long side of larger triangle: ((x+5) +30) and long side of smaller triangle (30)entire short side of larger triangle (36) and short side of smaller triangle (20)Since the parts labeled (x+5) and 16 are each the same fraction of their entire side, those parts are corresponding also, and will have the same proportion as other corresponding sides.

On the map of an amusement park on a coordinate grid, the skating rink is at (−1.5, −1).
The coordinate grid is shown from negative 3 to positive 3 on the x-axis and negative 3 to positive 3 on the y-axis. There are increments of 1 over 2 for each grid line on each of the two axes. Only the whole numbers are labeled on either side of the axis.
Which of these shows how to plot the point to mark the skating rink?
From the origin, move 1.5 units to the left along the x-axis and 1 unit vertically down, and place the point.
From the origin, move 1 unit to the left along the x-axis and 1.5 units vertically down, and place the point.
From the origin, move 1 unit to the right along the x-axis and 1.5 units vertically down, and place the point.
From the origin, move 1.5 units to the right along the x-axis and 1 unit vertically down, and place the point.
Answer:
The first option is correct.
Moving 1.5 units to the left (or -1.5 units to the right).
Moving 1 unit down (or -1 unit up).
Therefore you get the result of (-1.5, 1) as is the location of the rink.

Pls help ! find value of x
Answer:
dasd
Step-by-step explanation:
Given:
2(x + 5)-7= 3(x - 2)
To Find:
• Value of x
Solution:
⇒ 2(x + 5)-7= 3(x - 2)
⇒ 2x+10-7= 3x - 6
Rearranging the like terms,
⇒ 3x-2x = 10 + 6-7
⇒x=16-7
⇒x=9
Verification:
⇒ 2(x + 5)-7= 3(x - 2)
Putting x = 9,
⇒2(9+5)-7= 3(9 - 2)
2(14)-7= 3(7)
⇒28-7=21
⇒ 21 = 21
→ LHS = RHS
