Zombies scare everyone and a mummy is much like a zombie. In fact, their equations are parallel to each other. If the zombie equation is `y=7x+5` and the mummy equation passes through the point (3, 23), what is the mummy's equation?
Answer
y=7x+2
Step-by-step explanation:
you have your slope already so keep slope but remove 5 and turn it into b in order to solve for new equation ...
y=7x+b
sub in (3,23) in your equation
23=7(3) +b
23=21 +b
23-21=b
2=b
your new equation should be y=7x+2
Answer:
y=-1/7+23 3/7
Step-by-step explanation:
Since it's parallel you take the y=7x+5 and the 7 is turned into -1/7(to find what's PARALLEL)
Now you put it into point slope formula to get: y-3=-1/7(x-3)
Simplify the equation.

Is there enough information to prove the two triangles congruent? If yes, write the congruence statement and name the postulate you would use. If no, write not possible and tell what other information you would need.
Answer:
Step-by-step explanation:
yes, both are congruent by SAS Postulate
<SQP=<SQR (common in both (construction))
QS=QS (common side in both angle)
QP=QR ( as given)
hence, QPS=QRS
by SAS postulate
By SAS postulate Δ QSP ≅ Δ QSR.
What is Congruence Rule?The triangles are said to be congruent when two angles and a non-included side of one triangle match the corresponding angles and sides of another triangle.
When two angles and the included side of one triangle are equal to two angles and the included side of another triangle, two triangles are said to be congruent.
Given:
In Δ QSP and Δ QSR
<SQP=<SQR (common in both (construction))
QS=QS (common side in both angle)
QP=QR ( as given)
So, by SAS postulate Δ QSP ≅ Δ QSR.

A scooter travels 30 feet in 2 seconds at a constant speed.
What is the speed of the scooter in feet per second?
Answer:
15
Step-by-step explanation:
Since it goes 30 in 2 seconds, we need to divide 30 and 2 and end up with 15.
To make sure our answer is correct we know that 15 is one second, so we can add 15+15= which will give us 30, and will also land at 2
Brainliest pls
The speed of the scooter is 15 feet per second.
To calculate the speed of the scooter in feet per second, you can use the formula:
Speed = Distance / Time
The distance traveled by the scooter is 30 feet, and the time taken is 2 seconds.
Plugging these values into the formula, we get:
Speed = 30 feet / 2 seconds
Speed = 15 feet/second
Therefore, the speed of the scooter is 15 feet per second.

The $414 price charges a store for a small refrigerator consists of the refrigerator's original cost to the store plus a profit 15% what was the refrigerator's original cost to the store?
Answer:
$351.9Step-by-step explanation:
the question is not formatted well
A store charges $414 for a small refrigerator, the price consists of the refrigerator's original cost to the store plus a profit 15% what was the refrigerator's original cost to the store?
Step one:
given data
we are told that the price of the small refrigerator contains both the original price and 15% profit
mathematically
$414= original price + 15% profit
Step two:
let us solve for 15% of 414
=(15/100)*414
=0.15*414
=$62.1
This shows that the profit is $62.1
let the original price be x
$414= x + 62.1
solve for x
x=414-62.1
x=351.9
The refrigerator's original cost to the store $351.9

Asia is a chef in a restaurant. To prepare for dinner service, she chops 7 1/2 onions in 1/6 of an hour. What is Asia's rate of chopping in onions per hour?
Asia is a chef in a restaurant. To prepare for dinner service, she chops 7 1/2 onions in 1/6 of an hour. Asia's rate of chopping onions is 30 onions per hour.
From the information given;
Asia chops [tex]\mathbf{7 \dfrac{1}{2} \ onions }[/tex] in [tex]\mathbf{\dfrac{1}{6} \ hours}[/tex]So, the onion is given in mixed fraction which can be converted to an improper fraction as: [tex]\mathbf{\dfrac{15}{2}\ onions}[/tex]
Now,
if Asia chops [tex]\mathbf{\dfrac{15}{2}\ onions}[/tex] in [tex]\mathbf{\dfrac{1}{6} \ hours}[/tex] Then Asia will chop (x) onions in 1 hour.We can cross multiply the above two equations to determine the number of onions Asia will chop per hour as follows:
[tex]\mathbf{(x) \times \dfrac{1}{6} \ hours = \dfrac{15}{2} \ onions \times 1 \ hour}}[/tex]
Making (x) the subject of the formula:
[tex]\mathbf{(x)=\dfrac{ \dfrac{15}{2} \ onions \times 1 \ hour}{ \dfrac{1}{6} \ hours }}}[/tex]
[tex]\mathbf{(x)={ \dfrac{15}{2} \ onions } \times { \dfrac{6}{1} }}}[/tex]
(x) = 15 onions × 3
(x) = 30 onions per hour.
Therefore, Asia's rate of chopping onion is 30 onions per hour.

If Asia chops 7 1/2 onions in 1/6 hour, therefore, using proportion, the rate of chopping onions per hour is: 45 onions per hour.
Applying the knowledge of proportion and fractions, we can determine Asia's chopping rate of onions per hour.
Given:
Number of onions chopped in 16 hour = 7 1/2 onionsLet number of onions chopped in 1 hour be xUsing proportion, we have the following:
[tex]7\frac{1}{2} = \frac{1}{6} \\\\x = 1[/tex]
Cross multiply[tex]\frac{1}{6} \times x = 7\frac{1}{2} \times 1\\\\\frac{x}{6} = \frac{15}{2}[/tex]
Multiply both sides by 6[tex]\frac{x}{6} = \frac{15}{2}\\\\x = \frac{15}{2} \times 6\\\\x = 45[/tex]
Therefore, if Asia chops 7 1/2 onions in 1/6 hour, therefore, using proportion, the rate of chopping onions per hour is: 45 onions per hour.

What is a right-angle triangle?It is a type of triangle in which one angle is 90 degrees and it follows the Pythagoras theorem and we can use the trigonometry function. The Pythagoras is the sum of the square of two sides is equal to the square of the longest side.
The right-angle triangle is shown in a diagram. Then by the Pythagoras theorem, we have
P² = H² - B²
P² = 25² - 7²
P² = 625 - 49
P² = 576
P = 24

Put the following equation of a line into slope-intercept form, simplifying all fractions. 3x+4y=-4
Answer:
Don't come at me if I'm wrong, but I think it's y=-3/4x-1 1/3
Step-by-step explanation:
1) you have to subtract 3x from both sides (this makes it 4y=-3x-4)
2) you then divide by 4 on both sides (it will become y=-3/4=4/3)
3) then you simplify the fractions (it becomes y=-3/4x-1 1/3)
