Question is: Andre solved an equation, but when he checked his answer he saw his solution was incorrect. He knows he made a mistake, but can’t find it. Where is andres mistake and what is the solution to the equation?

Answers

Answer 1

Answer:

-1=x He messed up on the third step.

Step-by-step explanation:

I worked out the equation and found that when he switched -6x over to -4 he did not change the symbol. So instead of 6+4 he did 4-6. I finished the equation and got -1

what is the perpendicular slope intercept form?

Answers

Answer:

The point-slope form of the equation of the perpendicular line that goes through (5, 0) is:

[tex]y=-\frac{1}{2}x+\:\frac{5}{2}[/tex]

Step-by-step explanation:

Given the equation

[tex]y=2x-1[/tex]

comparing the equation with the slope-intercept form

[tex]y=mx+b[/tex]

Here,

m is the slope b is the intercept

so the slope of the line is 2.

As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line, so

The slope of the perpendicular line will be: -1/2

Therefore, the point-slope form of the equation of the perpendicular line that goes through (5, 0) is:

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y-0=\frac{-1}{2}\left(x-5\right)[/tex]

[tex]y=\frac{-1}{2}\left(x-5\right)[/tex]

[tex]\:y=-\frac{1}{2}x+5\cdot \:\frac{1}{2}[/tex]

[tex]y=-\frac{1}{2}x+\:\frac{5}{2}[/tex]

Mr. Gottula can eat two tacos in 8 minutes. Mrs. K can eat three tacos in 15 minutes.
(5a) Who eats tacos faster? How do you know? *

(5b) What is the UNIT RATE for Mr. Gottula? (In other words, how many minutes does it take for him to eat one taco?) *

(5c) At this rate, how long would it take Mr. Gottula to eat four tacos? *

Answers

(5a) Answer: Mr. Gottula eats the tacos faster

(5b) Answer: It takes Mr. Gottula 4 minutes to eat 1 taco

(5c) Answer: It will take Mr. Gottula 16 minutes to eat 4 tacos

Step-by-step explanation:

(5b) If we know that Mr. Gottula can eat two tacos every 8 minutes, and Mrs. K can eat three tacos in 15 minutes, first we have to find out how many tacos they eat in 1 minute. Finding how much they eat in one minute is mathematically called THE UNIT RATE. So to find the unit rate we have to divide the time it takes Mr. Gottula to eat the tacos by 2.

If Mr. Gottula can eat 2 tacos in eight minutes we have to find how much he can eat in one minute. So we have to divide the time Mr. Gottula took to ate by 2 and we also have to divide the tacos Mr. Gottula ate by 2. So now lets do the math, 8 divided by 2 is 4, and 2 divided by 2 is 1. So we now know the unite rate. Mr. Gottula ate 1 taco in 4 minutes. To find Mrs. k's unit rate we do the same thing, but we have to divide it by 3 since Mrs. k ate 3 tacos in 15 minutes. So we now have to find the unit rate for Mrs. k. Lets now do the math, 15 divided by 3 is 5 and 3 divided by 3 is 1. So now we know the unit rate of Mrs. k, Mrs. k ate 1 taco in 5 minutes. Mr. Gottula eats a taco every 4 minutes, while Mrs. K eats a taco every 5 minutes. So Mr. Gottula is eating faster.

(5c) So next it says "At this rate, how long would it take Mr. Gottula to eat four tacos?" So if we know that Mr. Gottula eats a taco every 4 minutes we just have to find out how many minutes will it take Mr. Gottula to eat 4 tacos. He eats 1 taco in 4 minutes so we have to multiply the tacos by 4 and we have to also multiply the time by 4 to find out how long it takes Mr. Gottula to eat 4 tacos. So lets do the math, 4 times 1 is 4 and 4 times 4 is 16 so we now know that Mr. Gottula eats 4 tacos in 16 minutes.

Explain why 2(z – 1) = 4(z + 5) has one solution. Choose the best response below.
A. The coefficients of z are the same, but the constant terms are different.
B. The coefficients of z are the same, but the constant terms are the same.
C. The coefficients of z are the same, and the constant terms are the same.
D. The coefficients of z are different, and the constant terms are different.

Answers

First to answer

Answer:

A. The coefficients of z are the same, but the constant terms are different.

Step By step Explanation:

2(z – 1) = 4(z + 5)

Step 1: Simplify both sides of the equation.

2(z−1)=4(z+5)

(2)(z)+(2)(−1)=(4)(z)+(4)(5)(Distribute)

2z+−2=4z+20

2z−2=4z+20

Step 2: Subtract 4z from both sides.

2z−2−4z=4z+20−4z

−2z−2=20

Step 3: Add 2 to both sides.

−2z−2+2=20+2

−2z=22

Step 4: Divide both sides by -2.

−2z/−2 = 22/−2

z=−11

The coefficients for z are the same, but the constants are different.

Tommy plans to attend the Clinton County Fair and is trying to decide what would be a better deal. He can pay $36 for unlimited rides, or he can pay $14 for admission plus $2 per ride. If Tommy goes on a certain number of rides, the two options wind up costing him the same amount. What is that cost? How many rides is that?

Answers

Let, n is the number of rides at which he pays same in both the deal.

Deal 1 :

Amount paid, A = $36 .

Deal 2 :

Amount paid, A = 14 + 2n

Equating both the equation, we get :

14 + 2n = 36

2n = 22

n = 11

Therefore, at a cost of $36 and at 11 rides both the deals are same.

Hence, this is the required solution.

Note: Depending on the fractions that you chosefor your ingredient amounts, it may not be possible to create each exact amount using only 13 and 14 measuring cups. If you need to, you can round your ingredient amounts using benchmarks and then explain how you would estimate that amount. For example, if you need 74 cup of an ingredient, 74cup is slightly more than 12 cup. You could fill up your 14 measuring cup twice to make 12 cup of that ingredient, and then add just a tiny bit more to estimate 74 cup.
