Answer:
(-1,-1)
Step-by-step explanation:
Because you're translating something 3 units to the left, then you are moving along the x-axis, so you will subtract 3 from 2.

Kenny lives in Greenpoint, where the cost of living increases by 8% every year. If Kenny
spends $50,700 this year, how much can he expect to spend 11 years from now to maintain
the same standard of living?
If necessary, round your answer to the nearest cent.
Using an exponential function, it is found that he must spend $118,214 in 11 years to keep the same standard of living.
What is an exponential function?An increasing exponential function is modeled by:
[tex]A(t) = A(0)(1 + r)^t[/tex]
In which:
A(0) is the initial value.r is the growth rate, as a decimal.His current cost of living is of $50,700, which increases by 8% yearly, hence A(0) = 50700, r = 0.08, and the equation is:
[tex]A(t) = A(0)(1 + r)^t[/tex]
[tex]A(t) = 50700(1 + 0.08)^t[/tex]
[tex]A(t) = 50700(1.08)^t[/tex]
After 11 years, the cost will be given by:
[tex]A(11) = 50700(1.08)^{11} = 118214[/tex]

Answer:
108 ft²
Step-by-step explanation:
Area of a rectangle = width × length
Area of a triangle = 1/2 × base × height
Surface area = rectange + rectangle + rectangle + 2 congruent triangles
= (3 × 8) + (4 × 8) + (5 × 8) + 2(1/2 ×3 × 4)
= 24 + 32 + 40 + 12
= 108 ft²

Step-by-step explanation:
Ankur estimated the quotient of 15 and one-third divided by (negative 4 and two-thirds) to be 3. Which best describes his error? Ankur multiplied the compatible numbers 15 and –3. Ankur found that the quotient of a positive number and a negative number is negative. Ankur found that the quotient of a positive number and a negative number is positive. Ankur added the compatible numbers 15 and –3.
Answer:
C. Ankur found that the quotient of a positive number and a negative number is positive
Step-by-step explanation:
Given the expression that is solved by Ankur as shown;
[tex]15 \frac{1}{3} \div(-4\frac{2}{3} )[/tex]
We were told that Ankur got 3. Let us evaluate to see ankurs error.
change to improper fraction first
[tex]= 15 \frac{1}{3} \div(-4\frac{2}{3} )\\= \frac{46}{3} \div \frac{-14}{3} \\= \frac{46}{3} \times \frac{-3}{14} \\= \frac{-46}{14}\\ = -3.28[/tex]
Note that from the calculation the quotient of a positive number to a negative number returns a negative number. Based on Ankur's answer, he got a postive value which is one of his errors. He found out that the quotient of a positive number and a negative number is positive which is wrong.
Hence the correct option is C
Answer:
Step-by-stepAnkur found that the quotient of a positive number and a negative number is negative
Step-by-step explanation:
Given that:
Quotient of 15 and one-third divided by (negative 4 and two-thirds) = 3
Mathematically,
( 15 1/3) ÷ (-4 2/3) = 3
Here,
Dividend = 15 1/3 (positive)
Divisor = - 4 2/3 (negative)
Dividing a positive Dividend by a negative Divisor will always give a negative quotient
Hence,
15 1/3 = 46 / 3
-4 2/3 = - 14 / 3
46/3 ÷ - 14/3
= 46/3 * -3 / 14
Ankur must have either forgotten or neglected the negative sign in the divisor explanation:
so the answer is b

Find the equation of a line that has the same slope as y = 6 - 2x and the same y-intercept as y= "-10x" – 4.
Search instead for Find the equation of a line that has the same slope as y = 6 - 2x and the same y-intercept as y= -10x – 4.
Answer:
y = - 2x - 4
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 6 - 2x = - 2x + 6 ← is in slope- intercept form
with slope m = - 2
y = - 10x - 4 ← is in slope- intercept form
eith y- intercept c = - 4
then
y = - 2x - 4 ← is the equation of the required line
Step-by-step explanation:
slope of y=6-2x=> -2 as it is in the form (y=mx+c )
y intercept of y=-10x-4=-4(as it in the form y=mx+c ,c is intercept made by y-axis)
so equation of line having-4 as y intercept and slope as -2 will be given by (intercept slope form):
that is y=mx+c
=> y= -2x-4=> 2x+y+4=0 is equation of required line

gcf/hcf : 2
4 and 6 :
4: 2 x 2
6: 2x 3
gcf/hcf : 2
why 6 and 12 don't work
6: 2 x 3
12: 2 x 2 x 3
they have 3 in common as well, meaning the hcf/gcf would be 2 x 3 which is 6, not 2

what is the point slope form of (-7,5) , (1,-1)
Answer:
y-5=-2/3(x-(-7))
Step-by-step explanation:
I just learned this recently as well so bare with me.
So the point slope form is y-y1=m(x-x1)
So first we have to find the slope. So we do 5-(-1)/-7-1=-6/8=-3/4
So now, we just have to plug in the numbers.
So y-5=-2/3(x-(-7)).
I know that looks a little funky but if you used the slope intercept form, you would get the same answer if you just simplified this version. Of course, you don't have to simplify this version because this version is completely acceptable.
I hope this helped.

-3x + 6 = 2x - 24 how do i do this its not high school btw its 8th grade
Answer:
x = 6
Step-by-step explanation:
Ok first you need to get to combine like terms, so first subtract six from the left so it cancels out the left side and what you do to one side you have to do it to the other so after you do that you get
-3x = 2x -30
then you subtract 2x from the right side and 2x on the left side getting
-5x = -30
your goal is to get by itself so what you can do is divide -5 on both sides getting
x = 6
if you are wondering why its a positive and not a negative its because a negative divided or multiply by a negative makes a positive.
Answer:
x=6
Step-by-step explanation:
-3x+6=2x-24
6=5x-24
30=5x divide both sides by 5
x=6
one leg of a right triangle is twice as long as the other leg, If the hypotenuse side is 5cm long then what is the measure of the shorter leg (you can leave your answer as a decimal or in radical form)
Step-by-step explanation:
Let the base be x and the perpendicular be y.
It is given that, one leg of a right triangle is twice as long as the other leg,
y = 2x ...(1)
Hypotenuse, H = 5 cm
We can use Pythagoras theorem as follows :
[tex]H^2=B^2+P^2[/tex]
Putting all the values,
[tex]5^2=x^2+(2x)^2\\\\25=x^2+4x^2\\\\25=5x^2\\\\x^2=5\\\\x=\sqrt{5}\ cm[/tex]
So, the base is [tex]\sqrt5\ cm[/tex]. No, to find the value of y put x in equation (1). So,
[tex]y=2x\\\\=2\sqrt{5} \ cm[/tex]
Hence, the measure of the shorter leg is [tex]\sqrt{5} \ cm[/tex]
Solve the system:
