y+2=-2(x-5)
What is the equation in slope-intercept form?
O y=-2x+12
O y=-2x+8
O y=-2x-7
y=-2x-3
Answer:
y=-2x+8
Step-by-step explanation:
When consider coordinate (5, -2)
y=-2x+8
When x=5
y= -2 x 5 + 8 = -2
Therefore the answer is y=-2x+8
Complete 4,5,6 for 25 points.
Answer:
Step-by-step explanation:
4. A = P + Prt
a. Solve for r
Prt = P - A
r = (P - A)/Pt
b. Solve for t
Prt = P - A
t = (P - A)/Pr
5. Ax + By = C
a. By = C - Ax
y = (C - Ax)/B
b. Ax = C - By
x = (C - By)/A
6. y = mx + b
a. mx + b = y
mx = y - b
x = (y - b)/m
b. mx + b = y
mx = y - b
m= (y - b)/x
c. mx + b = y
b = y - mx
How many 4-digit numbers are neither multiples of 2 nor multiples of 5?
Answer:
There are 7,200
Step-by-step explanation:
Hope this helps!
There are 8400 4-digit numbers that are neither multiples of 2 nor multiples of 5.
What is a sequence?The sequence is a pattern of placing the values in a specified manner.
To count the number of 4-digit numbers that are not multiples of 2 or 5, we can use the principle of inclusion-exclusion.
First, let's count the total number of 4-digit numbers. We know that the smallest 4-digit number is 1000 and the largest 4-digit number is 9999. Therefore, the total number of 4-digit numbers is:
9999 - 1000 + 1 = 9000
Next, let's count the number of 4-digit numbers that are multiples of 2. We know that a number is a multiple of 2 if its last digit is even, so half of the 10 possible digits can be the last digit of a multiple of 2. Therefore, there are:
5 × 10 × 10 = 500
4-digit multiples of 2.
Similarly, let's count the number of 4-digit numbers that are multiples of 5. We know that a number is a multiple of 5 if its last digit is 0 or 5. Therefore, there are:
2 × 10 × 10 = 200
4-digit multiples of 5.
Now, we need to subtract the number of 4-digit numbers that are multiples of both 2 and 5 (i.e., multiples of 10) since they were counted twice in the above calculations. There are:
1 × 10 × 10 = 100
4-digit multiples of 10.
Using the principle of inclusion-exclusion, the number of 4-digit numbers that are neither multiples of 2 nor multiples of 5 is:
9000 - 500 - 200 + 100 = 8400
Therefore, there are 8400 4-digit numbers that are neither multiples of 2 nor multiples of 5.

3x+y=9
5x+4y=22
Answer:
(2, 3) x=2, y=3
Step-by-step explanation:
There are two ways to solve this: substitution & elimination:
Using substitution for this equation:
[tex]\left \{ {{3x+y=9} \atop {5x+4y=22}} \right.[/tex]
3x + y =9
y = 9-3x
Substitute for y:
5x + 4(9 - 3x) = 22
5x + 36 - 12x = 22
-7x = -14
x = 2
Solve for y:
3(2) + y = 9
6 + y = 9
y = 3

What is the value of this expression when c= -4 and d = 10?
1/4(c3+d2)
The value of the expression using BODMAS rule is 9.
What is simplification?
To simplify the arithmetic expression involving more operators, we need to use BODMAS rule. The full form of BODMAS is Brackets (Parts of a calculation inside the bracket always come first), Precedence of brackets are : [{(bar)}], Orders (powers and square roots), Division, Multiplication, Addition, Subtraction.
For the given situation,
The values are c = -4, d = 10
The expression is 1/4(c^3+d^2)
Substitute the above values,
⇒ [tex]\frac{1}{4}(c^{3}+d^{2} )[/tex]
⇒ [tex]\frac{1}{4} (-4^{3} +10^{2} )[/tex]
⇒ [tex]\frac{1}{4}(-64+100)[/tex]
⇒ [tex]\frac{1}{4}(36)[/tex]
⇒ [tex]9[/tex]
Hence we can conclude that the value of the expression using BODMAS rule is 9.

Find the volume of sphere
Volume of a sphere is calculated using the following formula
[tex]V = \frac{4}{3} \pi r^{3}[/tex]
Where V = Volume and r = radius
By Substitution,
[tex]V = \frac{4}{3} \pi * 1^{3}\\\\V = \frac{4}{3} \pi * 1\\\\V = \frac{4}{3} \pi[/tex]
Solving further to get the numerical value of volume;
We have to substitute 3.14 for π

Mrs. Smith has $20,000 to invest. She wants to earn $10,000 in interest. She is considering a savingsand loans bank that is offering her 5.6% interest per year. For how long will she have to leave her money in the bank in order to reach her goal of $10,000?
Answer:
Number of year to get $10,000 as interest = 7.5 year (Approx)
Step-by-step explanation:
Given:
Initial investment = $20,000
Interest on investment = $10,000
Rate of interest = 5.6% = 0.056
Find:
Number of year to get $10,000 as interest:
Computation:
[tex]Interest\ on\ investment = Initial\ investment[(1+r)^n-1]\\\\10,000 = 20,000[(1+0.056)-1]\\\\0.5=(1.056)^n-1\\\\1.5 =(1.056)^n\\\\n=7.44[/tex]
Number of year to get $10,000 as interest = 7.44
Number of year to get $10,000 as interest = 7.5 year (Approx)

What is the longest line segment that can be drawn in a right rectangular prism that is 15cm long, 8 cm wide, and 7 cm talk
Answer:
=18.38cm
Step-by-step explanation:
The longest line segment in a right rectangular prism is the diagonal that connects two opposite vertices. On the first diagram attached, the green line segment connecting A and G is one such diagonals. The goal is to find the length of segment .
Look at the attached picture. The longest segment we can draw is AG (or any of its equivalent: BH, CE, DF). Let's focus on AG for example.
We can think of AG as the hypotenuse of triangle ACG. So, we need AC first. AC is itself the hypotenuse of triangle ABC,
so we have,
[tex]AC^2 = AB^2+BC^2=8^2+7^2=113[/tex]
Now we can resume where we stopped with triangle AGC, and we have
[tex]AG=\sqrt{AC^2+CG^2}=\sqrt{113+225}=\sqrt{338}[/tex]
=18.38cm

B
Answer:
AB ≈ 7.83
Step-by-step explanation:
Using the sine ratio in the right triangle
sin50° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{BC}{AB }[/tex] = [tex]\frac{6}{AB}[/tex]
Multiply both sides by AB
AB × sin50° = 6 ( divide both sides by sin50° )
AB = [tex]\frac{6}{sin50}[/tex] ≈ 7.83 ( to the nearest hundredth )
Solve the system using the method of you choice:
-x + 4y = 12
5x - 2y = -6
Answer:
(0, 3)
Step-by-step explanation:
Let's first eliminate x. To do this, multiply all three terms of the first equation by 5:
-5x + 20y = 60
5x - 2y = -6
----------------------
18y = 54, so that y = 3.
Substituting 3 for y in the first equation yields:
-x + 4(3) = 12, or -x = 0. Thus, x = 0, and the solution is
(0, 3)

A small TV that regularly sells for $89.00 is on sale at a 15% discount. What is the amount of discount?
Answer:
$13.35
Step-by-step explanation:
To find the amount of discount, multiply the discount rate by the usual price of the small TV.
discount rate * regular price
The discount rate is 15% and the regular price of the small TV is $89.00
15%*$89.00
15%*89
Convert 15% to a decimal by dividing 15 by 100, or moving the decimal place two spots to the left.
15/100=0.15
15.0-->1.5-->0.15
0.15*89
Multiply
13.35
The discount amount is $13.35
So the amount of discount is $13.35
Look at the attached picture
