Suppose you are given that a=5 and 4a + b=6. What can you prove by using these statements and the substitution property?
Using the values given for 'a' and the equation '4a + b = 6', we applied the substitution property to prove that the value of 'b' is -14.
Given that a=5 and 4a + b=6, we can use the substitution property to find the value of b. The substitution property allows us to replace a with 5 in the second equation.
Performing the substitution, we have:
Substitute a with 5 in 4a + b = 6, giving 4(5) + b = 6.This simplifies to 20 + b = 6.To find b, subtract 20 from both sides of the equation; b = 6 - 20.Hence, b = -14.By substituting and manipulating the equation, we prove that b equals -14 when a equals 5 and 4a + b equals 6.

the area of a rectangular field is 6603 meter squared. if the width of the field is 71 m what is it’s length
Area of rectangular field is 6603m². Given width 71m, length is 93m (6603 ÷ 71).
To find the length of the rectangular field, you can use the formula for the area of a rectangle:
[tex]\[ \text{Area} = \text{Length} \times \text{Width} \][/tex]
Given that the area is [tex]\( 6603 \, \text{m}^2 \)[/tex] and the width is [tex]\( 71 \, \text{m} \)[/tex], you can rearrange the formula to solve for the length:
[tex]\[ \text{Length} = \frac{\text{Area}}{\text{Width}} \][/tex]
Substitute the given values:
[tex]\[ \text{Length} = \frac{6603 \, \text{m}^2}{71 \, \text{m}} \][/tex]
[tex]\[ \text{Length} = 93 \, \text{m} \][/tex]
So, the length of the rectangular field is [tex]\( 93 \, \text{m} \).[/tex]

Fiona is serving iced tea and lemonade at a picnic. She has only 44 cups in which to serve the drinks. If x represents the number of glasses of iced tea and y represents the number of glasses of lemonade, which equation represents the number of glasses of iced tea she can serve?
Answer:
[tex]x=44-y[/tex]
Step-by-step explanation:
Let x represents the number of glasses of iced tea and y represents the number of glasses of lemonade.
We have been given that Fiona is serving iced tea and lemonade at a picnic. She has only 44 cups in which to serve the drinks. We can represent this information in an equation as:
[tex]x+y=44[/tex]
Since x represents the number of glasses of iced tea, so we will solve for x by subtracting y from both sides of our equation.
[tex]x+y-y=44-y[/tex]
[tex]x=44-y[/tex]
Therefore, the equation [tex]x=44-y[/tex] represents the number of glasses of iced tea Fiona can serve.

A rare bacterial culture is being grown in a lab. As time passes, the cells multiply in a specific pattern.After 1 day, there is only 1 cell.After 2 days, there are 9 cells.After 3 days, there are 20 cells.After 4 days, there are 34 cells.How many cells will there be after seven days?
a.149B.120C. 98D.94
the equation is,
a_n = a_(n–1) + 3 * n + 2
Substituting the values
for day 4,
20 + 3*4 + 2 = 34
Thus the equation is correct
Therefore to calculate for a_n at n = 7 or a_7, we must calculate a_5 and a_6 first.
a_5 = 34 + 3*5 + 2 = 51
a_6 = 51 + 3*6 + 2 = 71
Hence,
a_7 = 71 + 3*7 + 2 = 94

Estimate the area under the curve f(x) = x^2 from x = 1 to x = 5 by using four inscribed (under the curve) rectangles. Answer to the nearest integer.
Answer:
30 square units
Step-by-step explanation:
For a rectangle to be described as "inscribed" in the context of estimating the area under a curve, the entire rectangle should be positioned underneath the curve.
Therefore, as the curve of f(x) = x² is convex (concave up) in the interval [1, 5], to estimate the area under the curve by using inscribed rectangles, we can use the Left Riemann Sum.
The Left Riemann Sum is a numerical approximation method used to estimate the definite integral of a function over a given interval by dividing the interval into subintervals. It approximates the area under the curve of a function by using rectangles, where the left side of each rectangle touches the curve at the left endpoint of each subinterval.
[tex]\boxed{\begin{minipage}{11cm}\underline{Left Riemann Sum}\\\\$\displaystyle \int^b_a f(x)\; \text{d}x \approx \Delta x \left(f(x_0)+f(x_1)+f(x_2)+...+f(x_{n-2})+f(x_{n-1})\right)$\\\\$\text{where}\; \Delta x=\dfrac{b-a}{n}$\\\end{minipage}}[/tex]
The number of subintervals, n, is the number of rectangles used, and the interval is [a, b].
As the interval is [1, 5], this means that a = 1 and b = 5.
As the number of rectangles to use is 4, then n = 4.
Calculate the value of Δx:
[tex]\Delta x=\dfrac{b-a}{n}=\dfrac{5-1}{4}=\dfrac{4}{4}=1[/tex]
The given partition divides the interval [1, 5] into 4 subintervals where the width of each subinterval is one. Therefore, the left endpoints are:
[tex]x_0=1[/tex][tex]x_1=2[/tex][tex]x_2=3[/tex][tex]x_3=4[/tex]Substitute everything into the formula and solve:
[tex]\begin{aligned}\displaystyle \int^5_1 x^2\; \text{d}x &\approx 1\cdot \left(f(1)+f(2)+f(3)+f(4))\right)\\\\&=(1)^2+(2)^2+(3)^2+(4)^2\\\\&=1+4+9+16\\\\&=30\end{aligned}[/tex]
Therefore, the estimation of the area under the curve f(x) = x² from x = 1 to x = 5 using four inscribed rectangles is 30 square units.
Describe the possible values for x and y when ∣x − y ∣ > 0. What does it mean when ∣x − y ∣ = 0? Can ∣x − y ∣ < 0? Explain your reasoning.
The absolute value |x−y|>0 when x and y are different, |x−y|=0 when x and y are the same, and |x−y| cannot be < 0 because absolute values cannot be negative.
Explanation:The question is about absolute value, which refers to the distance of a number from zero on a number line. The notation |x−y| represents the absolute value of (x-y).
When |x−y|>0, it means that x and y are distinct from each other. For example, if x = 2 and y = 1, |x-y| equals |2-1|=1, which is indeed greater than 0. There are infinite such values for x and y as long as they are not the same.
When |x−y|=0, it implies that x and y are the same. The only way the absolute value of a number can be zero is when the number itself is zero. Therefore, this can only happen if x = y. If x and y are both 2, for example, |x-y| equals |2-2|=0.
|x−y| cannot be less than 0. The absolute value of a number can never be negative, because it represents the distance a number is from zero and distance cannot be negative.

In the diagram below de is parallel to xy what is the value of y?
Answer:
C. 75.
Step-by-step explanation:
We have been given a diagram of two parallel lines and we are asked to find the value of y.
We can see from our given diagram that angle y and the angle that measures 105 degrees is formed inside the parallel lines and on the same side of transversal.
Since the the angles formed on the same side of transversal and inside parallel lines are called consecutive interior angles and they add up-to 180 degrees, so we can set an equation as:
[tex]y^o+105^o=180^o[/tex]
[tex]y^o+105^o-105^o=180^o-105^o[/tex]
[tex]y^o=75^o[/tex]
Therefore, the value of y is 75 degrees and option C is the correct choice.
Marcus bought a shirt that was marked $28, but it was on sale for 15% off the marked price. what was the price of the shirt after the discount
Final answer:
To find the sale price of the shirt after a 15% discount on the marked price of $28, calculate the discount, subtract it from the original price, resulting in a sale price of $23.80.
Explanation:
Marcus bought a shirt that was marked $28, but it was on sale for 15% off the marked price. To calculate the price of the shirt after the discount, you first need to determine the amount of the discount. To do this, convert the percentage to a decimal by dividing by 100 (15% = 0.15) and then multiply this by the original price.
Discount amount = Original price × Discount rate
= $28 × 0.15
= $4.20.
Subtract the discount amount from the original price to find the sale price of the shirt:
Sale Price = Original price - Discount amount
= $28 - $4.20
= $23.80.
Therefore, the price of the shirt after the 15% discount is $23.80.
Jamarcus's employer pays 80 percent of his medical insurance. If the insurance costs Jamarcus $20 a week, how much is his employer paying?
Answer:
$80
Step-by-step explanation:
The total amount of his medical insurance is 100%. As such if Jamarcus's employer pays 80 percent , then the amount he pays would be equivalent to 20%.
As such, if the insurance costs Jamarcus $20 a week and the total amount is Y
then,
20% of Y = $20
0.2Y = $20
Y = $100
His employer will be paying
= 80% of $100
= $80
