Answer:
y = -0.25x + 2.25
Step-by-step explanation:
First, you can simplify the equation of the line it's perpendicular to (2y = 8x - 6) by dividing both sides by 2. This means you would get y = 4x - 3. From that you can conclude that the slope of that line is 4.
Lines always have a slope that is the negative reciprocal of the slope of the line they are perpendicular to, so you know the slope of the line is going to be -1/4.
So far, you have the equation y = -1/4x + b and you have to find b.
You can substitute in the point (-3, 3) so you would have 3= -1/4 * -3 + b
Solving,
3 = 3/4 + b
b = 2 and 1/4
Therefore the equation is y = -1/4x + 2 1/4 or y = -0.25x + 2.25
If f(x) = x + 7 and g(x) - what is (fºg)(x)?
0 4.
Answer:
The answer is last option choose it.
Step-by-step explanation:
Given
f(x) = x + 7
g(x) = 1/x
Now.
fg(x) = f (1/x)
= 1/x + 7

Write an equation in point-slope form of the line that has a slope of -3 and passes through the
point (4,-5)
Which is the corresponding angle
Answer:
4 and 8Step-by-step explanation:
4 and 8 are corresponding angles as they form at parallel lines cut by a transversal.
4 and 3 are supplementary angles (they both add up to 180°).
4 and 1 are vertically opposite angles and are equal to each other.
From the above explanations, only 4 and 8 are corresponding angles.

Divide £48 in the following ratios.
a 2:1 b) 1:3
Answer:
a) £32 and £16
b) £12 and £36
Step-by-step explanation:
It is given that:
Amount to divide = £ 48
a) 2 : 1
Let,
x be the times of share.
2x + x = 48
3x = 48
Dividing both sides by 3
[tex]\frac{3x}{3}=\frac{48}{3}\\x=16[/tex]
Thus,
2x = 2(16) = £32
x = £16
b) 1 : 3
x+3x=48
4x=48
Dividing both sides by 4
[tex]\frac{4x}{4}=\frac{48}{4}\\x=12[/tex]
x = £12
3x = 3(12) = £36
Therefore,
a) £32 and £16
b) £12 and £36

At the beginning of summer, Mark has $200 in savings and Ryan has $350. The brothers have mowing jobs set up for the summer. Because Mark is older, he receives $20 for each mowing job and Ryan receives $15. The brothers’ parents pay for the fuel used to mow, so all of the money the brothers earn goes to savings.
Write two equations, one for Mark and one for Ryan, to represent the money in savings (s) based on the number of mowing jobs (j) Mark and Ryan do.
Determine the number of mowing jobs it takes for Mark to have the same amount in savings as Ryan does. Show your work.
Answer:
30 jobsStep-by-step explanation:
Mark
Initial amount - $200Earning - $20*jSaving is: S = 20j + 200Ryan
Initial amount - $350Earning - $15*jSaving is: S = 15j + 350If they get same saving, then the equations will be equal:
20j + 200 = 15j + 35020j - 15j = 350 - 2005j = 150j = 150/5j = 30The answer is 30 mowing jobs

Calculate the circumference of a semi circle which diameter is 28cm
Answer:
Circumference of semi circle = 116 cm
Step-by-step explanation:
Given:
Diameter of a circle = 28 cm
Find:
Circumference of semi circle
Computation:
Circumference of semi circle = πr + Diameter
Circumference of semi circle = (22/7)(28) + 28
Circumference of semi circle = 88 + 28
Circumference of semi circle = 116 cm
Find the Shaded Area:
10 m
10 m
Answer:
100-25pi m
Step-by-step explanation:
Let us subtract the circles area from the square
First, let us find the area of the square:
Base x height =
10m x 10m = 100m
Now, the circle:
pi x radius ^2 =
pi x (10/2)^2 =
pi x 5^2=
25 pi
Therefore, the shaded area is 100-25pi m. You can also simplify it further by plugging in the 3.14... value into pi.

which equation can be used to solve 3/5 divided by 7/10
Answer:
35/50
Step-by-step explanation:
Here we will show you how to calculate 3/5 divided by 7/10. We will give you the answer in fraction form and in decimal form.
Here is 3/5 divided by 7/10 displayed
3/5 ÷ 7/10
The numbers in 3/5 divided by 7/10 are labeled below:
3 = dividend numerator
5 = dividend denominator
7 = divisor numerator
10 = divisor denominator
To make it a fraction form answer, you multiply the dividend numerator by the divisor denominator to make a new numerator.
Furthermore, you multiply the dividend denominator by the divisor numerator to make a new denominator:
3 x 10/5 x 7 = 30/35
Thus, the answer to 3/5 divided by 7/10 in fraction form is:
30/50

In a fish tank, 50% of the fish are clown fish, 1/3 are angel fish and the rest are goldfish. There are 33 clown fish in the fish tank. (b) How many goldfish are there in the fish tank?
Answer:
11 gold fish
Step-by-step explanation:
We are told that
In a fish tank, 50% of the fish are clown fish and there are 33 clown fish in the fish tank.
Let the total number of fishes in the tank be = x
Hence,
50% of x = 33
50/100 × x = 33
50x/100 = 33
Cross Multiplying
50x = 33 × 100
x = 33 × 100/50
x = 66 fishes
Hence, the total number of fishes in the tank = 66 fishes
1/3 are angel fish
The number of angel fishes are
1/3 × 66 fishes = 22 angel fish
•The rest are goldfish. How many goldfish are there in the fish tank?
The number of gold fish is calculated as:
Total number of fishes -( Number of clown fish + Number of angel fish)
= 66 - (33 + 22)
= 66 - 55
= 11
Therefore, the number of gold fish is 11
Answer:
Step-by-step explanation:
1/33 because its 33 goldfish
