The trapezoid below has been enlarged by a scale of 1.5. What is the area of the enlarged trapezoid?
Answers
Answer:
New area by scale of 1.5 = 81 in²
Step-by-step explanation:
Given:
Current area = 36 in²
Find:
New area by scale of 1.5
Computation:
New area by scale of 1.5 = Current area x (scale factor)²
New area by scale of 1.5 = 36 x (1.5)²
New area by scale of 1.5 = 36 x (2.25)
New area by scale of 1.5 = 81 in²
Answer:
B.
Step-by-step explanation:
We have been given that the trapezoid shown in the attachment has been enlarged by a scale of 1.5.
We are asked to find the area of the enlarged trapezoid. The area of the original trapezoid is 36 square inches.
Since each side of the trapezoid is enlarged 1.5 times, so the area of new trapezoid would be 2.25 times greater than area of original trapezoid.
The area would be 2.25 times greater because area is product of sum of lengths of parallel sides and height.
Therefore, the area of the enlarged trapezoid would be and option B is the correct choice.

how do i graph y=-x+3
Answers
Answer:
y=-x+3 follows the same equation as y=mx+b
3 is b, and b is the y-intercept. The y intercept is where the line crosses on the y axis, and -x is is m, which is the slope. However since its a variable, its point is on the same number as positive three on the y axis, so then its 3 on the x axis.

1.6(b+3.5)=20
if answered correctly i will give brainliest
Answers
Answer:
Step-by-step explanation:
20/1.6=12.5
12.5-3.5=9
9=b
9
Explanation:
First you multiply 1.6 by b and 3.5.
1.6b+5.6=20
Then you move everything besides b over to one side and change the sign.
1.6b=20-5.6
Next you subtract 20 by 5.6.
20-5.6=14.4
Finally you divide 1.6 by both sides.
b=14.4/1.6
b=9

Zachary is standing in a stadium and has the option of running up a staircase or down a staircase for exercise.
The function f(x)= 1/25(∣4x∣+2x) will determine how many calories Zachary will burn if he runs up x steps. Use a negative value for x if he runs down the stairs. What does the domain represent in this function?
Answers
Answer:
R(All real numbers)
Step-by-step explanation:
We are given that the calories burn in x steps of running is given by
[tex]f(x)=\frac{1}{25}(|4x|+2x)[/tex]
We have to find the domain of this function.
We know that
|x|=[tex]x, x\geq 0[/tex]
-x, x<0
Therefore, the function
[tex]f(x)=\frac{1}{25}(4x+2x) ,x\geq 0[/tex]
[tex]\frac{1}{25}(-4x+2x) ,x<0[/tex]
[tex]f(x)=\frac{1}{25}(6x), x\geq 0[/tex]
[tex]\frac{1}{25}(-2x), x<0[/tex]
The function is defined for all values of x.
Therefore, the domain of f(x)=All real numbers (R)

Step-by-step explanation:
[tex]\displaystyle \frac{2x}{x-4}-\frac{2x-5}{x^2-10x+24}=\frac{-3}{x-6}[/tex]1. Factor the denominator.
[tex]\displaystyle \frac{2x}{x-4}-\frac{2x-5}{(x-6)(x-4)}=\frac{-3}{x-6}[/tex]2. Multiply the leftmost fraction by (x-6)/(x-6) to get common denominators.
[tex]\displaystyle \Big ( \frac{x-6}{x-6} \Big ) \frac{2x}{x-4}-\frac{2x-5}{(x-6)(x-4)}=\frac{-3}{x-6}[/tex]3. Simplify.
[tex]\displaystyle \frac{2x^2-12x}{(x-4)(x-6)}-\frac{2x-5}{(x-6)(x-4)}=\frac{-3}{x-6}[/tex]4. Combine like terms.
[tex]\displaystyle \frac{2x^2-14x+5}{(x-4)(x-6)}=\frac{-3}{x-6}[/tex]5. Multiply the right side of the equation by (x-4)/(x-4).
[tex]\displaystyle \frac{2x^2-14x+5}{(x-4)(x-6)}=\frac{-3}{x-6} \Big ( \frac{x-4}{x-4} \Big )[/tex]6. Simplify.
[tex]\displaystyle \frac{2x^2-14x+5}{(x-4)(x-6)}=\frac{-3x+12}{(x-6)(x-4)}[/tex]7. "Cancel" out the denominators because they are equivalent.
[tex]2x^2-14x+5=-3x+12[/tex]8. Set the equation equal to 0.
[tex]2x^2-11x-7=0[/tex]Quadratic formula:
[tex]\displaystyle x = \frac{-b\pm \sqrt{b^2-4ac} }{2a}[/tex]9. Factor using the quadratic formula.
[tex]\displaystyle x = \frac{-(-11)\pm \sqrt{(-11)^2-4(2)(-7)} }{2(2)}[/tex]10. Multiply and simplify.
[tex]\displaystyle x = \frac{11 \pm \sqrt{177} }{4}[/tex]11. Plug this into your calculator and solve for x.
[tex]x=6.07603367 \approx 6.08[/tex] [tex]x=-0.57603367 \approx -0.58[/tex]The correct answer is A. x = 6.08, x = -0.58.

Reasoning Solve the system of linear equations using substitution. Use pencil and paper. Which expression would be easier to substitute into the other equation, in order to solve this problem? Explain your reasoning. x = 4y - 2 x + 4y =7
Answers
Answer:
x = 5 /2 , y = 9 / 8
Step-by-step explanation:
x = 4y - 2 ....... (i)
x + 4y =7 ....... (ii)
Substituting eqn (i) into eqn (ii);
(4y - 2 ) + 4y = 7
4y - 2 + 4y = 7
8y = 7 + 2 = 9
y = 9 / 8
substitute y = 9 / 8 in eqn (i)
x = 4 (9 / 8) - 2
x = 9 / 2 - 2
x = (9 - 4 ) / 2
x = 5 / 2
