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

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]
Given the sequence, 3, -9,27,-81 ...
What is the 15th term, assuming the pattern continues
Fist : 3
then
second : x (-3) = - 9
third : x (-3) = 27
x (-3) = - 81
the 15 term ?
first one = 3 x (-3)⁰
second one = 3 x (-3)¹
third one = 3 x (-3)²
so n one = 3 x (-3)ⁿ⁻¹
then the 15th one = 3 x (-3)¹⁴

Step-by-step explanation:
This is correct because we already know that the two sides are congruent and that we have one more side we need to prove congruent. Well, it is congruent because it's just lined up next to each other, so they're equal which is BD=DB. This would make it so it would be SSS and the two triangles are congruent.

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:
width = 3 cm
Step-by-step explanation:
the area (A) of a rectangle is calculated as
A = length × width
given A = 27 and length = 9 , then
9 × width = 27 ( divide both sides by 9 )
width = 3 cm
❝ Area of a rectangle is ❞ = ❝ Length × Width ❞
✠ Given terms :

Answer:
y = 2
Step-by-step explanation:
Rearrange terms
3y -4 = -2y +6
Add 4 to both side
3y -4 +4 = -2y +6+4
Simplify
3y = -2y + 10
Add 2y to both sides
3y +2y = -2y + 10 +2y
Simplify
5y = 10
Divide both sides by the same factor
5y/5 = 10/5
Simplify
y = 2

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

During math class last week, Terrence was asked to determine if the equation shown has no solution, one solution, or infinitely many solutions
101 - 6+ 2. = 4(3x - 1) - 2
Terrence concluded that the equation has infinitely many solutions
Determine if Terrence's conclusion is correct that the equation has infinitely many solutions
Show each step of your work and justity your thinking
Enter your answer work, and justification in the box provided
The equation can have no solution or as many solutions as possible
Terrence's conclusion that the equation has infinitely many solutions is false
How to determine the number of solutions?The equation is given as:
101 - 6+ 2 = 4(3x - 1) - 2
Open the bracket
101 - 6+ 2 = 12x - 4 - 2
Collect the like terms
12x = 101 - 6+ 2 + 4 + 2
Evaluate the like terms
12x = 103
Divide both sides by 12
x =103/12
The above shows that the equation has one solution
Hence, Terrence's conclusion that the equation has infinitely many solutions is false

-1 from each side

divide both sides by 5
x=6
m∠ ( 5x + 1 )° will be equal to m∠31° because they both are vertically opposite angles.
Which means :-
[tex]5x + 1 = 31[/tex]
[tex]5x = 31 - 1[/tex]
[tex]5x = 30[/tex]
[tex]x = \frac{30}{5} [/tex]
