I believe it is B. I did not look at the both the given points but one of the points that are unidentified and one of the given points:
(0, -8) and (2, -2)
To find slope use this equation:
(Y2 - Y1)/(X2 + X1)
Input the points into the equation:
(-2 - (-8))/(2 - 0) —> (-2 + 8)/(2 - 0)
You find that it becomes:
6/2
Then simplify it:
3/1
So the answer is A
Answer:
x<-6
Step-by-step explanation:
3x+4>5(x+2)
Distribute
3x+4 > 5x+10
Subtract 3x from each side
3x+4 -3x> 5x-3x+10
4 > 2x+10
Subtract 10 from each side
4-10 > 2x+10-10
-6 > 2x
Divide each side by 3
-6/2 > 2x/2
-3 > x
Since x must be less than -3 the only statement that would be true is x< -6
1)
a. y=mx+b
m=slope
b=y-intercept
y=20x+40
The slope is 20.
The y-intercept is 40.
b. y =cost
x= # of shirts
y=20x+40
15 sweatshirts would make the equation y=20(15)+40
y=300+40
y=340
15 shirts would cost $340.
c. y=20x+40
$1000 would make the equation 1000=20x+40
1960=20x
98=x
Paying $1000 would get the swim team 98 shirts.
2)
(1,5) (4,11)
(x,y) (x1, y1)
y+y1=m(x+x1)
Pick a point and substitute it into the equation.
y+5=m(x+1)
To find the slope of a line, use the following equatIon:
y-y1/x-x1
11-5/4-1
6/3=2
The slope of the line is 2. Plug it into the equation for m.
y+5=2(x+1)
Solve the equation.
y+5=2x+2
y+3=2x
Put the equation in slope-intercept form.
y=2x-3
3)
y=x-25
y=6x-5
Plug one equation into the other.
x+25=6x-5
Solve.
x+30=6x
30=5x
6=x
Now plug 6 into one of the equations.
y=6x-5
y=6(6)-5
y=36-5
y=31
The answer should be in the form of a point.
(6,31)
5) I'm sorry, don't know how to solve this. You can Google how to graph two inequalities, though.
6)
Antonio's age can be represented by x.
Sarah's age can be represented by y.
2x+y=35
5x=y
Plug 5x into the first equation.
2x+5x=35
Solve.
7x=35
x=5
Antonio is 5 years old.
To find Sarah's age, plug Antonio's age into the equation for Sarah's age.
5x=y
5(5)=y
25=y
Sarah is 25 years old.
Answer:
$252,990
Step-by-step explanation:
Cost of the Home=$213,000.
Hilda makes a down payment of 5%, 5% of $213,000 =$10,650
Amount Borrowed=$213,000-10,650=$202,350
Monthly Payment=$1,517.80.
Number of Payment =25 Years X 12 =300 Payments
Total Payments = 300 X $1,517.80=$455340
Interest Paid by Hilda =Total Payment-Amount Borrowed
=$455,340-202,350
=$252,990
Based on the data set shown, which of the following is a true statement? -1, -1, 0, 1, 1, 1, 1, 2, 2, 2, 3
babymother [125]
<span>-1, -1, 0, 1, 1, 1, 1, 2, 2, 2, 3
Median=1
</span><span>Mean=(-1+-1+0+1+1+1+1+2+2+2+3)/11=11/11=1
Mode=1
So the first option is true
Answer: mean=mode</span>
