Answer:
y = |x - 4|
Step-by-step explanation:
Because the x value is the only variable that changed, it means the graph has moved only horizontally. The only value you are adding to will be inside the absolute value, not outside (as that is vertical transformation)
If that is the case, the graph has only moved right from (1, 1) to (4, 1), and thus from the parent graph y = |x| you would derive y = |x - 4|.
Simon makes 30 cakes He gives 1/5 of the cakes to sali He gives 10% of the cake to Jane What fraction of 30 does he have left
Answer:
7/10 or 0.7 or 70% left.
Step-by-step explanation:
Since he gives 1/5 of the cake to Sali, he gave 1/5 * 30 = 6 cakes away to Sali. Since 10% is 1/10, he gave away 1/10 * 30 = 3 cakes away to Jane. He has a total of 30 - 3 - 6 = 21 cakes left. 21/30 = 7/10, or 0.7, or 70% left.
Answer: 21/30
Explanation this is because 1/5of 30 is 6 and 10 percent of 30 is 3
6+3=9
30-9=21
Therefore Simon has 21/30 cakes left

An AP has 15 terms and a common
difference of - 3. Find its first and last terms
if its sum is
b 15
d -120
a 120
Answer:
Step-by-step explanation:
Sum =n/2{2a+(n-1)d
When sum=15 and d=-3
15=15/2{2a+(15-1)-3}
15=7.5{2a+(14)-3}
15=7.5{2a+(-42)}
15=7.5(2a-42)
15=15a-315
15+315=15a
330=15a
a=330/15
=22
a=22
Last term=a+(n-1)d
=22+(15-1)-3
=22+(14)-3
=22-42
= -20
When sum=120
Sum=n/2{2a+(n-1)d
120=15/2{2a+(15-1}-3
120=7.5{2a+(14)-3}
120=7.5{2a+(-42)}
120=7.5(2a-42)
120=15a-315
120+315=15a
435=15a
a=435/15
=29
a=29
Last term=a+(n-1)d
=29+(15-1)-3
=29+(14)-3
=29-42
= -13
When sum= -120
Sum=n/2{2a+(n-1)d
-120=15/2{2a+(15-1)-3
-120=7.5{2a+(14)-3}
-120=7.5{2a+(-42)}
-120=7.5(2a-42)
-120=15a-315
-120+315=15a
195=15a
a=195/15
a=13
Last term=a+(n-1)d
=13+(15-1)-3
=13-42
= -29
The perimeters of the square and the regular pentagon are equal. A square with side lengths of 3x + 3. A pentagon with side lengths of x + 8.
Answer:
60
Step-by-step explanation:
Since the perimeters are equal then:
(3x + 3) * 4 = (x + 8) * 5
12x + 12 = 5x + 40
7x = 28
x =4
Perimeter of square = (3*4 + 3) * 4 =
(12 + 3) * 4 = 60
Perimeter of pentagon = (4 + 8) * 5 =
(12) * 5 = 60
The answer is 60
Is (1, 2) a solution of the system y>2x and x+y<3?
Answer:
no
Step-by-step explanation:
Let's check the first statement. 1 > 2 * 2 becomes 1 > 4. This is a false statement so the answer is no.
It is not a solution. 2x=2 and 2 is not bigger than 2 (which is y).
x+y = 1+2=3. # is not bigger than 3.

(25 POINTS) Write the inequality of the following graph?
Answer:
f(x) > -x + 2
Step-by-step explanation:
First I found the equation of the line.
The y intercept is at 2 so I know to add 2 at the end
The slope is -1 since it is going downwards
Since the top side is shaded, that represents greater than, if it was shaded downwards, it would be less than
Putting all that together, the equation is f(x) > -x + 2
The cost of 3 cans of pineapple at Superway Store is $2.25, and the cost of 6
cans of the same kind of pineapple is $4.80 at Grocery Giant. Which store
has the better price for the pineapple?
Answer:
Grocery Giant has the better price for the pineapple.
Step-by-step explanation:
Superway Store
3 cans of pineapple is 2.25
Grocery Giant
6 cans of pineapple is 4.80
Superway Store 6 cans is 2.25 + 2.25 = 4.50
Which means that Superway Store is cheaper by 30 cents

What is the measure of an angle that is nine times it’s complement
Answer:
9
Step-by-step explanation:
Assume that the measure of the angle is x
That would mean that the compliment of that angle would be 9x
Two angles are complementary when their sum equals 90
That means x + 9x equals 90.
We can combine x and 9x into 10x, leaving us with 10x=90
Divide both sides by 10
x=9
The number of milligrams of a certain medicine a veterinarian gives to a dog varies directly with the weight of the dog. If the veterinarian gives a 30-pound dog Three-fifths milligram of the medicine, which equation relates the weight, w, and the dosage, d? d = StartFraction 1 Over 50 EndFraction w d = three-fifths w d = 18 w d = 50 w
Answer:
Step-by-step explanation:
A direct variation equation is of the form
y = kx,
where, in words, it reads "y varies directly with x" or "y varies directly as x". In order to use this as a model, we have to have enough information to solve for k, the constant of variation. The constant of variation is kind of like the slope in a straight line. It rises or falls at a steady level; it is the rate of change.
We have that a vet gives a dose of three-fifths mg to a 30 pound dog. If the dose varies directly with the weight of the dog, then our equation is
d = kw and we need to find k in order to have the model for dosing the animals.
[tex]\frac{3}{5} =k(30)[/tex]
Divide both sides by 1/30 to get k alone.
[tex](\frac{1}{30})(\frac{3}{5})=k[/tex] and
[tex]k=\frac{1}{50}[/tex]
Our model then is
[tex]d=\frac{1}{50}w[/tex]
This means that for every pound of weight, the dog will get one-fiftieth of a mg of medicine.

can someone help me to find tsa of entire solid ?
Step-by-step explanation:
Radius is same in both cones....
Slant height of lower cone = 50 cm ( by applying Pythagorean theorem )
TSA of the lower cone = 22/7 × 14 × ( 14 + 50 )
= 2816 cm^2
Total height of the solid = 52.8 cm
Height of the upper cone = 52.8 - 48 = 4.8 cm
TSA of the upper cone = 22/7 × 14 × ( 14 + 4.8 )
= 827..2 cm^2
TSA of the solid = 2816 + 827.2 = 3643.2 cm^2
the radius of wheel of a bicycle is 40 cm. taking pie =3.14, a)find tthe circumference of the wheel.b) find the distance covered by the bicycle in 200 complete revolution of the wheel.please ans this question. i beg you
Answer:
a)=251.2 cm b)=50240 cm
Step-by-step explanation:
a) The formula for calculating the circumference of a circle is c=d*pie, where D is the diameter of the circle.
Therefore, C = 2 * 40 * 3.14 = 251.2 cm
b) The distance covered by 200 revolutions of the wheel is 200 times the circumference, 200*251.2=50240 cm.So to think about this we can assume that there is a point A on the wheel, the distance that point A travels when it rotates 200 times.

Mr. Mole left his burrow and started digging his way down.
A represents Mr. Mole's altitude relative to the ground (in meters) after t minutes.
A= -2.3t – 7
How fast did Mr. Mole descend?
Answer:
He's descending at a pace of 2.3 meters per minute.
Step-by-step explanation:
This is because the equation shows us the slope or the speed he's going at.
A= -2.3t - 7
A= Altitude
-2.3 = Slope
- 7 is his starting altitude in meters
But every minute, t, he is going down 2.3 meters. It's easier to think about if you consider, A = y, and, t = x. Now you have the equation, y = -2.3x - 7.
And you graph it to see the progression in slope.
