Answer:
c; infinite solutions
Step-by-step explanation:
to solve this system of equations you can use elimination
you can divide all of the top by 2
you get
3x + y = 6
and then
-3x - y = -6
but then when you subtract them you get 0 = 0
this means it is infinite solutions
another way to tell that it is infinite solutions is by seeing if the equations are the same
-3x - y = -6 is just 3x + y = 6 but everything is multiplied by -1
Answer:
INFINITE SOLUTIONS
Step-by-step explanation:
So let's solve this system using elimination
we can convert the second equation to
-6x-2y = -12
6x+2y = 12
if we add these to equations we get 0 = 0
therefore, there are infinite solutions to this system
∠A and ∠B are complementary. The measure of ∠A is 21°.
What is the measure of ∠B?
Enter your answer in the box.
<B be y
We know that complementary angles have sum 90°[tex]\\ \sf\longmapsto y+21=90[/tex]
[tex]\\ \sf\longmapsto y=90-21[/tex]
[tex]\\ \sf\longmapsto y=69°[/tex]
<A=69°
Answer:
The measure of ∠B is 69°
Step-by-step explanation:
Given :
=> ∠A + ∠B = 90°
=> 21° + ∠B = 90°
=> ∠B = 90°- 21°
=> ∠B = 69°
Write a linear equation given the point and slope. (-7, 13); slope = -2
Answer:
y = -2x + 1
Step-by-step explanation:
The linear equation is generally written in y = mx + b form. Since m (the value of the slope) is already given, only the value of b must be determined. To do this, plug in x, y, and m for their values in the equation to get:
13 = -2 (-7) + b
Then, simplify.
13 = 14 + b
b = -1
Once you find the b value, plug everything back in and get y = -2x + 1.

Answer:
The answer is -1
Step-by-step explanation:
If you have 3 and you take away 4, so you end up with a negative number. or what you can do is also just flip the numbers around so subtract 4 minus 3 and put a negative sign when the first number is less than the second one!!

On a standardized test, Jose scored an 87 and Mia scored a 74. The distribution of test scores for the population is normal with a population mean of 76.28 and a population standard deviation of 7.02.
What percentage of people received a higher score than Jose?
Using the normal distribution, it is found that 6.3% of people received a higher score than Jose.
Normal Probability DistributionIn a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.In this problem, the mean and the standard deviation are given by, respectively: [tex]\mu = 76.28, \sigma = 7.02[/tex].
The proportion of people who received a higher score than Jose is one subtracted by the p-value of Z when X = 87, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{87 - 76.28}{7.02}[/tex]
[tex]Z = 1.53[/tex]
[tex]Z = 1.53[/tex] has a p-value of 0.937.
1 - 0.937 = 0.063.
6.3% of people received a higher score than Jose.

9514 1404 393
Answer:
1/3 hour per mile3 miles per hourStep-by-step explanation:
Time per mile can be found by dividing hours by miles:
(1/8 h)/(3/8 mi) = 1/3 h/mi
It will take him 1/3 hour to run 1 mile.
__
Miles per hour can be found by dividing miles by hours (or by finding the reciprocal of the above value):
(3/8 mi)/(1/8 h) = 3/1 mi/h = 3 mi/h
He could run 3 miles in one hour.

$6.00, plus 2.5% when converting to the local currency. How much will his bank charge in fees?
Answer:
$9.75Step-by-step explanation:
Given
The sum taken = $150One off fee = $6Rate of conversion = 2.5%Total fees
6 + 150*0.025 = 6 + 3.75 = $9.75Answer:
$9.75
Step-by-step explanation:
Take the percentage off what he withdrew.
2.5% = 0.025
150 * 0.025 = 3.75
Add the transaction fee.
6 + 3.75 = $9.75

joe has read 30% of a book. He has 56 more pages to finish. How many pages are there in the book?
Answer:
80 pages
Step-by-step explanation:
If Joe has read 30% and 56 pages is 70% of the book. We divide 56 by 7 and get 8 meaning that 10% of the book is 8. Once we know this we multiply 8 x 10 and get the amount of pages in the book 80
Answer:
There are 80 pages left.
Step-by-step explanation:
100% - 30% = 70%
70% = 56 pages
Insert x into a equation.
0.7x = 56
Multiply by 10 on both sides to get rid of the decimal.
0.7x = 56
· 10 ·10
Divide by 7 on both sides to get x by itself.
7x = 560
7
x = 80

What's the exact area and the exact perimeter of square EFGH shown in the coordinate plane?
Using the distance between two points to find the length of the side of the square, it is found that:
The area is of 50 square units.The perimeter is of [tex]20\sqrt{2}[/tex] units.Hence, option A is correct.The distance between two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by:
[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]
In this problem, the length of the side of the square can be found as the distance between points G and H, that is, the distance between (0,5) and (-5,0), hence:
[tex]l = \sqrt{(0 - (-5))^2 + (5 - 0)^2} = \sqrt{50} = \sqrt{2 \times 25} = 5\sqrt{2}[/tex]
The area of a square of side length l is given by:
[tex]A = l^2[/tex]
Hence:
[tex]A = (5\sqrt{2})^2 = 50[/tex]
The area is of 50 square units.
The perimeter of a square of side length l is given by:
[tex]P = 4l[/tex]
Hence:
[tex]P = 4(5\sqrt{2}) = 20\sqrt{2}[/tex]
The perimeter is of [tex]20\sqrt{2}[/tex] units.

Given the polynomial, f(x)= x³ + kx² - 2x + 1, and that f(x) is divided x-k the remainder is k, find the possible values of k.
Answer:
k=1
Step-by-step explanation:
According to the remainder Theorem, if we have a polynomial then if it divided by (x-a), the remained will be equal to
[tex]f(a)[/tex]
So we know that the factor is
[tex](x - k)[/tex]
So plug in k into the polynomial
[tex]f(k) = k {}^{3} + k(k) {}^{2} - 2(k) + 1 = k[/tex]
[tex]k {}^{3} + k {}^{3} - 2k + 1 = k[/tex]
[tex]2k {}^{3} - 3k + 1 = 0[/tex]
Solve for k.
Using Rational Roots Theorem, one possible root is 1 so we have
[tex]2k {}^{2} + 2k - 1 = 0[/tex]
Since that is irreducible over reals, 1 is our only factor so k=1.
