Please help with these two asap
Answer:
[tex]1.\ y = 2x - 1[/tex]
[tex]2.\ y = -4x + 5[/tex]
Step-by-step explanation:
Solving (1): The line equation in y intercept form;
Given
[tex]m = 2[/tex]
[tex](x_1,y_1) = (4,7)[/tex]
This is calculated using the following formula
[tex]y - y_1 = m(x - x_1)[/tex]
Substitute values for m, x1 and y1
[tex]y - 7 = 2(x - 4)[/tex]
Open Bracket
[tex]y - 7 = 2x - 8[/tex]
Make y the subject
[tex]y = 2x - 8 + 7[/tex]
[tex]y = 2x - 1[/tex]
Solving (2): The line equation in y intercept form;
Given
[tex]m = -4[/tex]
[tex](x_1,y_1) = (-1,9)[/tex]
This is calculated using the following formula
[tex]y - y_1 = m(x - x_1)[/tex]
Substitute values for m, x1 and y1
[tex]y - 9 = -4(x - (-1))[/tex]
[tex]y - 9 = -4(x + 1)[/tex]
Open Bracket
[tex]y - 9 = -4x - 4[/tex]
Make y the subject
[tex]y = -4x - 4 + 9[/tex]
[tex]y = -4x + 5[/tex]
LESSON: SOLVING QUADRATICS EQUATIONS
solve the equation. check your solutions.
1.) x^2+9=0
2.) x^2-4= -11
Step-by-step explanation:
x² + 9= 0
(move internode)
x²= -9 (heve no solution and parentheses )
if the number is negative and we are asked to find the root of n (if n is an even number). then it has no solution. example that have solution:
x²= 9
x = √9
x= 3
because, (3)²= (3) × (3)
= 9
or it could be: (-3)²
= 9
You must use parentheses if you want to convert it to the square root
2. x² - 4= -11
(move internode)
x²= -11 + 4
x²= -7 (haven't no solution because 7 is not the number of the square root and there are no brackets)

Alicia earned d dollars baby-sitting. Her friend earned twice as much. You earned $2 less than Alicia's friend earned. Write an expression in simplest form that represents the total amount in the situation.
Answer:
[tex]Total = \$5d - 2[/tex]
Step-by-step explanation:
Represent Alice with A, her friend with F and you with Y.
From the question, we have:
[tex]A = \$d[/tex]
[tex]F = 2 * A[/tex] --- Twice as much Alice means 2 times Alice's earnings
[tex]Y = F - 2[/tex] --- 2 less than her friend
Required
Determine the total amount
[tex]A = \$d[/tex]
Substitute [tex]\$d[/tex] for A in [tex]F = 2 * A[/tex]
[tex]F = 2 * \$d[/tex]
[tex]F = \$2d[/tex]
Substitute [tex]\$2d[/tex] for F in [tex]Y = F - 2[/tex]
[tex]Y = \$2d - 2[/tex]
The total amount is calculated by adding the earnings of Alice, her friend and you
[tex]Total = A + F + Y[/tex]
[tex]Total = \$d + \$2d + \$2d - 2[/tex]
[tex]Total = \$5d - 2[/tex]
Hence, the total earnings is 5d - 2
65 divided by 8 with the explanition
Answer:
8 1/8 or 8.125
Step-by-step explanation:
8 goes into 64 8 times. There is a remainder of 1 left over. When you divide 1 by 8, you get .125. That is added to 8.
The solution of expression after divide is,
⇒ 8.125
What is Division method?Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that'
The expression is,
⇒ 65 divided by 8
Now, We can divide as;
⇒ 65 divided by 8
⇒ 65 ÷ 8
⇒ 8.125
Thus, The solution of expression after divide is,
⇒ 8.125

the density of a substance is 2.5 cm calculate the volume of the substance if its mass is 25.0 grams
Answer:
10 cm³
Step-by-step explanation:
The equation for density is: d = m/v, where d is the density, m is the mass, and v is the volume.
Here, d = 2.5 and m = 25.0, so plug these into the equation to solve for v:
d = m/v
2.5 = 25/v
Multiply both sides by v:
2.5v = 25
Divide by 2.5:
v = 25/2.5 = 10
Thus, the volume is 10 cm³.
Mr. Lopez has 238 silver coins in his coin collection. The actual weight of the real silver in each coin is 0.85 ounce. How many ounces of real silver does Mr. Lopez have in his coin collection?
Answer:
202.3 ounces of real silver
Step-by-step explanation:
Another example would be like pizza. If there are 6 slices of pizza in each box, then 2 boxes of pizza would have 6 + 6 slices = 12 slices. It is 6 slices each * 2 boxes = 12 slices total. The same applies to the coin situation, for every additional coin, multiply 0.85 by the number of coins to get the total weight of real silver.
If there are 238 silver coins, then you have 238 0.85 ounces of real silver. Multiplying 238 by 0.85 to simplify gives you 202.3 ounces of real silver.

The perimeter is the distance around the composite shape, which is composed of a rectangle and a semi- circle.
P = 12 + 16 + 12 + πr ← ( rectangle and semi- circle )
= 40 + (3.14 × 8)
= 40 + 25.12
= 65.12 in
----------------------------------
A = (16 × 12) + (0.5πr² ) ← rectangle and semi- circle

by the given equation. Using this equation, find out the
maximum amount of profit the company can make, to the
nearest dollar.
y = –2x2 + 105x – 773
Answer:
The maximum profit will be: $605.125
Step-by-step explanation:
Given the function
[tex]y\:=\:-2x^2\:+\:105x\:-\:773[/tex]
The given equation is a quadratic function. It represents Parabola. The parabola opens down because of the negative leading coefficient (-2).
Thus, the maximum profit would be computed at the vertex of the graph.
Thus, we have to determine the value of y when x is the line of symmetry.
We can find this by the equation
x = -b/2a
where a = -2, b = 105
x = -105 / 2(-2)
x = -105 / -4
x = 105/4
x = 26.25
Now, putting x = 26.25 in the original function to find the value of 'y'.
[tex]y\:=\:-2x^2\:+\:105x\:-\:773[/tex]
[tex]y=-2\left(26.25\right)^2+105\left(26.25\right)-773[/tex]
[tex]y=-2\cdot \:26.25^2+105\cdot \:26.25-773[/tex]
[tex]y=1983.25-1378.125[/tex]
[tex]y=605.125[/tex]
Therefore, the maximum profit will be: $605.125
Answer: 605
y=$605→Max profit

A rectangular carpet has a perimeter of 274 inches. The length of the carpet is 95 inches more than the width. What are the dimensions of the carpet?
Answer:
Length: 116
Width: 21
Step-by-step explanation:
Let's say that the width of carpet is x. If the length of the carpet is 95 inches more than the width, then let's say that the width is x + 95.
Since we are solving for the perimeter, you have to multiply the width and the length(x and x + 95) by two.
So,
2x + 2x + 190 = 274.
Simplify this and you get:
4x= 274 - 190
4x = 84
x= 21
So, the width is 21. This means that the length is 21 + 95.
21 + 95 = 116
The circle graph shows how a family spends its annual income. If $29,400 is used for Entertainment and Savings combined, what is the total annual income?
Housing
25%
Savings
8%
Insurance
9%
Food
18%
Entertainment
13%
Clothing
14%
Auto
13%
Answer:
The annual income is 140,000 dollars
Step-by-step explanation:
If you add the percentage of Entertainment and Savings, you will get a total of 21%. 21% is equal to 0.21. If you divide 29,400 (the Corresponding value to the fraction) by 0.21 (the Corresponding fraction to its value). You will get 140,000 dollars. By dividing 29,400 by 0.21, it means that you will get the value of 1 whole of the amount of annual income.

find the measure of line segment MK
9514 1404 393
Answer:
21
Step-by-step explanation:
When secants meet, the product of the length of the pieces from the meeting point to the two circle intersection points is the same for all.
KL·KM = KJ·KC
Assuming the marks inside the circle apply only to the lengths inside the circle:
8(8+x+5) = 7(7+2x+1)
104 +8x = 56 +14x
48 = 6x
8 = x
Then the measure of MK is ...
MK = x+13 = 8+13
MK = 21
18 - 3z = 2z - 6z - 3. x=
(fraction)
Answer:
-21
Step-by-step explanation:
18-3z = 2z - 6z -3
18-3z = -4z -3
-3z+4z= -3-18
z=-21
Answer:
If you mean "z" instead of "x", the answer should be -21.
Step-by-step explanation:
18 - 3z = 2z - 6z - 3
-3z - 2z + 6z = -18 - 3
z = -21

You can use the law of cosines for the purpose.
b² = a² +c² -2ac·cos(B)
b² = 120² +110² -2(120)(110)·cos(20°) ≈ 1692.1148
b ≈ √1692.1148 ≈ 41.13532
