Which statement is true about the solution to the two equations? (1 point)

2 answers:

8 0

The first statement is true, because
|3x-1|+7=2 => |3x-1| = -5 (There is no solution. The absolute value is always positive, or zero).
|2x+1| +4=3 => |2x+1|=-1 (There is no solution either, for the same reason).

Answer:

the first statement is correct

Step-by-step explanation:

l3x - 1| + 7 = 2 and |2x + 1| + 4 = 3

-Equation 1 and equation 2 have no solutions.

-Equation 1 has no solution, and equation 2 has solutions x = 0, 1.

-The solutions to equation 1 are x = -1.3, 2, and equation 2 has no solution.

-The solutions to equation 1 are x = -1.3, 2, and equation 2 has solutions x = 0, 1.

Joe tracked the height of his Dalmatian puppy from age 13 weeks to 25 weeks. He graphed the data and determined the line of best

nadya68 [22]

Answer:

22.5 weeks

Step-by-step explanation:

y = 1.12x + 28.78 represents the height of the puppy. Here that height is 54 cm:

Then 54 = y = 1.12x + 28.78

Combining the constants, we get 1.12x = 25.22. Dividing both sides by 1.12, x turns out to be 22.5 weeks.

Judy Clark went to Reel Bank. She borrowed $7,800 at a rate of 6 1/2%. The date of the loan was September 2. Judy hoped to repay

abruzzese [7]

Answer:

$7995.85

Step-by-step explanation:

We will use simple interest formula to solve our given problem.

$A=P(1+rt)$ , where,

A = Amount after t years,

P = Principal amount,

r = Annual interest rate in decimal form,

t = Time in years.

$r=6.5\%=\frac{6.5}{100}=0.065$

$t=\text{141 days}=\frac{141}{365}\text{ year}$

$A=\$78001+0.065\times \frac{141}{365})$

$A=\$7800(1+0.065\times 0.38630136986)$

$A=\$7800(1+0.025109589041)$

$A=\$7800(1.025109589041)$

$A=\$7995.85479$

$A\approx \$7995.85$

Therefore, Judy will will pay back on January 20: $7995.85.

Mnenie [13.5K]

The correct option that shows the population of the research carried out by Matthew is;

Option D; all the students attending the college

We are told that Matthew wants to estimate the mean height of students attending his college.

Now, let us say the total number of students in his college is x. If he decides to select 100 students randomly to record their height, it means this 100 students is a sample out of the total number of students which is x that is the population.

In conclusion, we can say that the population of this research by Matthew is the total number of students that attend the college.
