x = 13, y = 18
hope this is right
Answer:
x=−3 and y=−2
Step-by-step explanation:
-5x+4(-2x-8)=7
-13x-32=7
-13x-32+32=7+32
-13x=39
divide both sides by -13
x=-3
substitute x for -3
-2(-3)-8= -2
y= -2
The discriminant if a quadratic equation is negative. One solution is 4 + 7i. What is the other solution? *
7 - 4i
4 - 7i
- 4 + 7i
7 + 4i
==========================================================
Explanation:
When you have a quadratic in the form ax^2 + bx + c = 0, where a,b,c are real numbers, then a negative discriminant leads to having a pair of complex roots. The roots come in conjugate pairs meaning that p+qi is one root while p-qi is the other root. The p,q are real numbers.
In the case of 4+7i being one root, we have p = 4 and q = 7, since it matches with p+qi. The other root must be 4-7i since it matches with p-qi.
In short, we flip the plus to a minus when going from 4+7i to 4-7i. All of this applies when we have a,b,c as real numbers.
If we allowed a,b,c to be complex numbers, then the roots may not necessarily come in conjugate pairs.

Write the number below as a fraction in its simplest form 0.˙49˙9 (more clearer picture is attached here)
Answer:
499/999
Step-by-step explanation:
The decimal number written is:
0.499...
Such that these 3 decimals are repeated as:
0.499499499...
Let's define this number as k
k = 0.499...
Let's multiply this number by 1000 (the same number of zeros as important decimals after the decimal point)
we get:
1000*k = (1000)*(0.499...) = 499.499...
Now we can subtract the original number k, so we get:
1000*k - k = 499.499... - 0.499...
In this way, we remove the part after the decimal point:
1000*k - k = 499.499... - 0.499...
(1000 - 1)*k = 499
999*k = 499
Now we can divide both sides by 999
(999*k)/999 = 499/999
k = 499/999
The fraction notation of our number is 499/999 (and this is the simplest form)
Question 7: The ratio of M's to A's cat is 5:7. Meg's cat weighs 20 kg. How
much more does Anne's cat weigh?
A) 28 kg
B) 2 kg
C) 8 kg
D) 9.3 kg
Answer: C
Step-by-step explanation: The ratio shows that Anne's cat is 2kg heavier, but Meg's cat weighs 20kg which is 4 times what the ratio shows the weight is, so the difference of the weight is also 4 times greater, which is 8kg!
The value of weight of Anne's cat will be 28 kg. Then the correct option is A.
What is the ratio?The utilization of two or more additional numbers that compares is known as the ratio.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
The ratio of M's to A's cat is 5:7. Meg's cat weighs 20 kg.
Let 'x' be the weight of Anne's cat. Then the equation is given as,
5 / 7 = 20 / x
Simplify the equation, then we have
5 / 7 = 20 / x
1 / 7 = 4 / x
x = 28 kg
The value of weight of Anne's cat will be 28 kg. Then the correct option is A.

Find the perimeter of the figure to the nearest hundredth.
In 2016 the U.S. Census Bureau estimated the population of the United States at 322 million. If the annual rate of growth was about 0.81%, find the expected population at the time of the 2030 census. Round your answer to the nearest ten million.
Answer:
388,000,000
Step-by-step explanation:
So as we have 322 million
we want to take 0.81% of it and add to the total each year so
322,000,000*0.81%=2,608,200
322,000,000+2,608,200=324,608,200
and now do that for 22 more years so
We get 387,649,305.98 as our population
387,649,305.98 -------> 388,000,000

What is the slop and the y-intercept on the graph?
Answer:
Slope= 2 ; y intercept= 4
Step-by-step explanation:
Slope: (y2 - y1)/(x2-x1) where x and y indicate the coordinates of two points
Slope = (4-0)/(0-(-2) = 4/2 = 2
y intercept is where the line intercepts the y axis: it happens in (0;4)
Answer:
y intercept is 4 and slope is 2

Hey! It's me again! You told me to answer this, so I will deliver ☺
Answer:
15/21
Step-by-step Explanation:
Because 1/3 and 2/7 do not have the same denominator, we will have to multiply them to get one that they'll both share.
In this case, you multiply both denominators, 3 and 7, to get 21.
We do the same with the numerators, but in a different way.
We're gonna multiply the numerators by the OTHER fractions' denominators this time. So, we do this:
1 x 7 = 7
2 x 3 = 6
We end up getting these fractions:
7/21
6/21
And now, we just subtract 6 from 21, to get 15.
And you get 15/21.

A restaurant has many vistors over the weekend.4/9 of the visitors are adults. If there were 380 adults, how many visitors were children? Answer
Answer:
475 children
Step-by-step explanation:
A restaurant has many vistors over the weekend.4/9 of the visitors are adults. If there were 380 adults, how many visitors were children? Answer
Step 1
We find the total number of visitors the restaurant had over the weekend. This is calculated as:
Let the total number of visitors = x
4/9 × Total number of visitors = 380 Adults
4/9 × x = 380
4x/9 = 380
Cross Multiply
4x = 9 × 380
x = 9 × 380/4
x = 855 visitors.
Step 2
The number of visitors that were children is calculated as:
Total number of visitors - Number of Adults
= 855 visitors - 380 Adults
= 475 children
