I was confused over this particular question. if you could help, I'd really appreciate it.
Step-by-step explanation:
The 1st equation is in slope-intercept form.
=> Slope = 4
The 2nd equation is in point-slope form.
=> Slope = -1/4
Since their slopes are unequal,
The lines are not parallel to each other.
However the product of their slopes is -1,
Therefore the lines are perpendicular to each other.
The answer is the 2nd option.

6(g-3)=12 can someone show the working out ik the answer but i dont get the working out
Answer:
g = 5
Step-by-step explanation:
6(g-3)=12
6g-18 = 12
6g = 30
g = 5
Answer:
g = 5
Step-by-step explanation:
→ Expand the bracket
6g - 18 = 12
→ Add 18 to both sides to isolate 6g
6g = 30
→ Divide both sides by 6 to isolate g
g = 5
Solve 9x-17=5x-1
What is x?
Answer: x=4 hope this helps:)
Step-by-step explanation:
Answer:
x=-4
Step-by-step explanation:
9x-17=5x-1 isolate X
9x-17=5x-1 add +1 to each side of the equation 9x-17+1=5x-1+1 the ones cancels out... 9x-16=5x
add -9x to both sides..... 9x-16+9x=5x-9x...... 9x-9x-16=5x-9x
-16=5x-9x subtract 5x-9x
-16= - 4x divide both sides by -4
-4=x or x=-4

What factoring method do you use to factor u²+70
1) difference of
squares
2) GCF
3) not foctorable
4) factor trinomial
Answer: 3) Not factorable
We cannot use the difference of squares method because we don't have a subtraction going on (ie "difference") and we don't have two perfect squares. The value 70 is not a perfect square.
We cannot factor out a GCF since the GCF here is 1, and that doesn't really affect things. Choice 4 is also not applicable because we don't have a trinomial. A trinomial has three terms.
A large box of pencils contains 45 pencils. A small box of pencils contains 25 pencils.
How many more pencils are in 18 large boxes than in 18 small boxes?
180 pencils
360 pencils
450 pencils
810 pencils
Answer:
360 more pencils.
45x18=810 large pencils
25x18=450 small pencils
810-450+360
Step-by-step explanation:
</3 PureBeauty
Answer:
360
Step-by-step explanation:
So we do 45*18 for the large boxes which is 810 and 25*18 for the small boxes which is 450 so now we subtract 450 from 810 which is 360!
Please help:In our amusement park that we built this week, the ride Diablo's
Domain had revenue of $250,000,000 in its first year as expected.
The company paid $750,000 for insurance or $3 for every $1,000
in revenue. If the park is wildly successful and revenue increases by
25% in the second year and the rate of $3 for every $1,000 holds
true, how much would it pay for insurance? Do you think it's
reasonable for insurance costs to increase proportionally? Why or
why not?

The half-life of a certain radioactive substance is 14 days. There are 6.6 grams of the substance
present initially. Which equation represents the number of grams of the radioactive substance
on day 42?
Answer:
A(t) = 0.825 g
Step-by-step explanation:
To solve this for amount remaining, we will use the equation;
A(t) = A_o × (½)^(t/t_½)
We are given;
Initial amount; A_o = 6.6 g
Half life; t_½ = 14
Time elapsed; t = 42
A(t) is amount of substance remaining
Thus;
A(t) = 6.6 × (1/2)^(42/14)
A(t) = 6.6 × (1/2)³
A(t) = 6.6 × ⅛
A(t) = 0.825 g

Michael is buying a pair of jeans that regularly cost $40. They are on sale for 20% off. If the tax rate is 6%, what is the sale price of the Jeans
including tax?
Answer:
The jeans will cost 33.92
Step-by-step explanation:
20% of 40 is 8, and 40 - 8 is 32.
6% of 32 is 1.92 and 32 + 1.92 is 33.92

Five more than three times a number is twenty-six. What is the number
Answer:
7
Step-by-step explanation:
3x+5=26
3x=21
----------
3
x=7
The required number is 7.
What are linear equation?A linear equation only has one or two variables. No variables in a linear equation is raised to power greater than 1 or used as denominator of a fraction.
Now it is given that, Five more than three times a number is twenty-six.
Let the number be x.
So, Five more than three times a number = 5 +3x
and this is equal to 26
So, the required equation we get,
5 +3x = 26
Subtracting 5 both the side we get,
5 +3x - 5 = 26 - 5
Solving we get,
3x = 21
Dividing both the side by 3 we get,
x = 7
Hence the number is 7.

Find the equation of the line.
Use exact numbers
Answer:
[tex]y=-\frac{1}{3} x+5[/tex]
Step-by-step explanation:
This question is asking for slope-intercept form which is y=mx+b, where m is the slope and b is the y-intercept. First, find the slope; this can be done in two ways, counting change in y and x then dividing, or using the formula [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]. Either way for this graph the slope comes out as -1/3. Next, find the y-intercept, this is where the line intersects with the y-axis. In this case, the line touches the axis at 5, therefore 5 is the value of b.
One of the legs of a right triangle measures 15 cm and its hypotenuse measures 17 cm. Find the measure of the other leg. If necessary, round to the nearest tenth.
Answer:
8
Step-by-step explanation:
The Pythagorean theorem shows us that the measure of the sides in a right triangle can be calculated using the formula a^2 + b^2 = c^2. Using this formula, and filling in the blank, we can conclude that the other leg measures 8 cm.

Find the solution to the systems of equations using the elimination method.
2x + 3y = 11
5x + 3y = 14
Answer:
x = 1 ; y = 3
Step-by-step explanation:
5(2x + 3y = 11)
2(5x + 3y + 14)
(distribute)
10x + 15y = 55
10x + 6y = 28
(subtract)
9y = 27
(divided 9 to both sides)
9 divided by 9 cancels out and 27 divided by 9 = 3
so..
y = 3
now, using any equation, (i’ll be using 2x + 3y =11) plug in the y value to find the x value
2x + 3y = 11
2x + 3(3) = 11
(multiply 3 x 3)
2x + 9 = 11
(subtract 9 from 9 and 11)
2x = 2
(divide 2 from both sides)
2 divided by 2 = 1
therefore...
x = 1
