Answer:
Television = $200 and DVD player = $450
Step-by-step explanation:
→ Make 2 equations
Televisions = t and DVD players = d
2t + 3d = 1750
4t + d = 1250
→ Multiply the bottom equation by 3 to make the same variable of d
2t + 3d = 1750
12t + 3d = 3750
→ Minus the two equations to isolate the d variable
-10t = -2000
→ Divide both sides by -10 to find the cost of one television
t = 200
→ Substitute t = 200 back into 4t + d = 1250
800 + d = 1250
→ Minus 800 from both sides to isolate d
d = 450
how many tens should be added to 56 to get 506
Answer:
Step-by-step explanation:
56+ ? = 506
? = 506 - 56
506 - 56
= 450
Answer 450
or 45 tens
45 tens must be added to get 506
What is Place Value?In math, every digit in a number has a place value. Place value can be defined as the value represented by a digit in a number based on its position in the number. For example, the place value of 7 in 3,743 is 7 hundred or 700. However, the place value of 7 in 7,432 is 7 thousand or 7,000.
Given here: The number 56
To convert it to 506 we must add 506-56=450
∴ we must 45×10 to 56 to convert it to 506
Hence, 45 tens must be added to get 506

Complete the coordinate proof of the theorem. Given: A B C D is a rectangle. Prove: The diagonals of A B C D are congruent.
Art: A rectangle is graphed on a coordinate plane. The horizontal x-axis and vertical y-axis are solid. The vertex labeled as A lies on begin ordered pair 0 comma 0 end ordered pair. The vertex labeled as B lies on begin ordered pair a comma 0 end ordered pair. The vertex labeled as D lies on begin ordered pair 0 comma b end ordered pair. The vertex C is unlabeled. Diagonals A C and B D are drawn by dotted lines.
The coordinates of rectangle ABCD are A(0, 0), B(a, 0), C( , ), and D(0, b). The length of AC⎯⎯⎯⎯⎯ is equal to . The length of BD⎯⎯⎯⎯⎯ is equal to . The diagonals of the rectangle have the same length. Therefore, AC⎯⎯⎯⎯⎯ is congruent to BD⎯⎯⎯⎯⎯.
Step-by-step explanation:
Given coordinates of the rectangle ABCD:
A(0, 0), B(a, 0), C(x, y), D(0, b)Lets first find coordinates of C
We can see that A and B are on same line horizontally, so C and D will be on the parallel line
The distance AB and CD are equal also distance AD and BC are equal, therefore
AB = a - 0 = a, CD = aAD = b - 0 = b, BC = bSo the coordinates of C are:
x = a, y = bNow the diagonals:
AC = √(a-0)² + (b-0)² = √a²+b²BD =√(0-a)² + (b -0)² = √a² + b²Since AC = BD, we can state they are congruent

4 - 3|x + 1| < -17
Answer: x > 6, x < -8
Subtract 4 from both sides.
−3∣x+1∣<−17−4
Then simplify -17 - 4 to -21.
−3∣x+1∣<−21
Divide both sides by −3.
|x + 1| > -21/-3
Two negatives make a positive.
|x + 1| > 21/3
simplify 21/3 to 7
Break down the problem into these 2 equations.
x + 1 > 7
-(x + 1) > 7
Solve the 1st equation: x + 1 > 7
x > 6
Solve the 2nd equation: -(x + 1) > 7
x < -8
last collect all solutions
x > 6, x < -8
A random sample of 12 chemists from Washington stats shows an average salary of $39,420 with a standard deviation of $1659. A random sample of 26 chemists from New Mexico has an average salary of $30,215 with a standard deviation of $4116. Find the 98% confidence interval of the difference of means.
Answer:
Step-by-step explanation:
Given that :
μ1 = 39420 ; σ1 = 1659 ; s1 = 12
μ2 = 30215 ; σ2 = 4116 ; s2 = 26
df1 = 12 - 1 = 11
df2 = 26 - 1 = 25
98 % confidence interval of the difference in sample means :
Pooled Variance :
S²p = ((df1 * s1²) + (df2 * s2²)) / (df1 + df2)
((11×1659^2)+(25×4116^2))÷(11+25) = 12605874.75
Standard Error :
√(S²p/n1) + (S²p/n2)
√(12605874.75/12) + (12605874.75/26)
= 1239.0847

Using the given sets of points, identify slope (m), y-intercept (b), and write the equation. (0, 4) and (-1, -1)
Answer:
y = 5x + 4
Step-by-step explanation:
Its a given that the y intercept is 4 because on that point x = 0
B= 4
now you solve for your slope using y - y' / x - x'
when you plug in the numbers you get -1 - 4 / -1 - 0 which simplfies to -5 / -1 which simplifies just to 5, so we know the slope is = 5
now we just plug In and the base equation is y = mx + b.
