x=-2y+1. and 3x+8y=11
Answer:
x=-7
y=4
Step-by-step explanation:
I am assuming you want the values of x and y. We know that x=-2y+1 and 3x+8y=11. We can substitute the value of x (-2y+1) into the equation 3x+8y=11.
Therefore 3(-2y+1)+8y=11
Using the distributive property:
-6y+3+8y=11
2y+3=11
y=4
To solve for x, we will plug in 4 in -2y+1. So, x= -2(4)+1=-7.
Check: 3(-7)+8(4)=-21+32=11.

What is the slope-intercept form of the following equation?
-3x+2y=12
Options:
2y= 3x+12
y=− 3/2x+6
y= 3/2x+6
y= 3/2x−6
Answer:
y = 3/2x + 6
Step-by-step explanation:
1. Add 3x to both sides (2y=3x+12)
2. Divide both sides by 2 to isolate the y (y=3/2+6)
You have 28m of fencing to make a rectangular garden. What different sizes of rectangular gardens could you make with this fencing? Illustrate. What gardens could you not make? What is the largest garden you could makeI'll
The area of a shape is the amount of space it occupies.
The largest garden you could make is 49 square meters
The perimeter is given as:
[tex]\mathbf{Perimeter = 28}[/tex]
This is calculated as:
[tex]\mathbf{2 \times (Length + Width) = 28}[/tex]
Divide by 2
[tex]\mathbf{Length + Width = 14}[/tex]
This means that, the sum of the dimensions must equal 14.
So, the possible dimensions are:
1 by 13 meters2 by 12 meters3 by 11 meters4 by 10 meters5 by 9 meters6 by 8 meters7 by 7 metersThe garden with the largest dimension is: 7 by 7 meters.
So, the area of garden is:
[tex]\mathbf{Area = 7m \times 7m}[/tex]
[tex]\mathbf{Area = 49m^2}[/tex]
The largest garden you could make is 49 square meters

Need help with number 4 and 5
Answer:
4. B
5. D
Step-by-step explanation:
4. Draw a line at angle to the line segment JK.
Then make three arcs on the new line using a compass without changing the setting.
Join the last arc to the endpoint of the line segment (in this case, K) and draw two parallel lines originating from the other two arcs.
5. Recall, there are two lines a and b
where x is the geometric mean.
Draw a line.
Label a point on the line (say, R)
Construct a segment (or arc) with endpoint R and length "a".
Construct a segment (or arc) with length "b" adjacent to the previous segment.
Label the endpoints (say, S and T). The line segment from point RS is "a" and that from point ST is "b".
Construct the perpendicular bisected of segment RT.
Label the midpoint of segment RT.
Using the midpoint as the center and half the length of RT as the radius, construct a semicircle.
At S, construct the perpendicular to segment RT. Label the intersection between the semicircle and perpendicular (say, Y)
SY is the geometric mean.
a/x = x/b is RS/SY = SY/ST

800 is 5 1/4% of what number
Answer:
42
Step-by-step explanation:
The number is 15,238.1.
What is Number system?
A system of writing to express the number is called number system.
Given that;
The expression is;
''800 is 5 1/4% of number''
Now,
Let a number = x
Then, Expression is written as;
800 = 5 1/4% of x
800 = 21/4% × x
800 = 21/400 × x
x = 800 × 400 / 21
x = 15,238.1
Thus, The number is 15,238.1.

What is the equation in slope-intercept form for a line that passes through the points (-5, 5) and
(-45, 80)?
Answer:
y = -15/8x - 35/8
Step-by-step explanation:
Find the slope = [tex]\frac{change in y}{change in x}[/tex]
= [tex]\frac{80 - 5}{-45 - (-5}[/tex])
= [tex]\frac{75}{-40}[/tex]
= [tex]\frac{-15}{8}[/tex]
Find the y-intercept Use one point (-5, 5) and the slope [tex]\frac{-15}{8}[/tex]
y = mx + b
5 = -15/8 (-5) + b
5 = 75/8 + b
5 - 75/8 = b
-35/8 = b
Write the equation
y = -15/8x - 35/8

Assume that the weight of chocolates in boxes of 'celebrations' chocolates in the UK are approximately normally distributed with N(μ=5.8,σ=1.3). Also assume that only those chocolates that weigh between 5 grams and 7 grams can be included for sale in the boxes. State the probability that a randomly chosen chocolate can be included for sale in the celebrations boxes.
Using the normal distribution principle ; the probability that a randomly chosen chocolate is in the celebration box is 0.553
μ=5.8 ; σ=1.3Zscore = (X - μ) ÷ σ
For X = 5 :
Zscore = (5 - 5.8) ÷ 1.3 = - 0.615
For X = 7 :
Zscore = (7 - 5.8) ÷ 1.3 = 0.923
Using a normal distribution table :
P(Z < 0.923) = 0.822
P(Z < - 0.615) = 0.269
P(Z < 0.923) - P(Z < - 0.615) = 0.822 - 0.269 = 0.553
Therefore, the probability of inclusion is 0.553.

-(Simplify your answers. Type integers or decimals.)
9514 1404 393
Answer:
3 times
Step-by-step explanation:
We observe that both functions are vertically scaled versions of the parent quadratic y = x^2. The ratio of scale factors is 2.7/0.9 = 3. That is, ...
g(x) = 3f(x)
This means that whatever vertical difference f(x) may show over the interval, g(x) will show 3 times that difference.
The average rate of change of g(x) is 3 times that of f(x).

how do you find the area of a circle
Answer:
A=πr2
Step-by-step explanation:
Area of a circle is found by the following formula-
Area of Circle = πr^2
Where -
π = pie, value of 3.14 or 22/7
r = radius of a circle
Example -
A circle has a radius of 10 cm. Find the area of the circle.
Solution -
Area of Circle = A=πr^2
A = 3.14*10^2
A= 314 cm
Note - Most preferably, 3.14 is the most common value used for pie. You can also use 22/7, and would end up with roughly the same answer, but it takes more time to solve with a fraction like 22/7.

1/2/x=2/0.6 what is x
Answer:
x = 0.15
Step-by-step explanation:
We have two equivalent ratios: 0.5 (or 1/2)/x = 2/0.6. It looks like our Giant One is 4/4, since 0.5 * 4 = 2. We can divide 0.6 by 4 to find the value of x. 0.6/4 = 0.15, so x = 0.15.
