Answer:
7 + 5i
Step-by-step explanation:
What is the square root of 25? Start by thinking about that.
Well, it's 5.
But because the 25 isn't positive, it's negative.
The square is 5i.
Then, you get 7 + 5i.
That can't be simplified any more, so that's your final equation.

Which equation represents a line which is perpendicular to the line
6x + 7y = -42?
Somebody please help?
Answer:
y = [tex]\frac{7}{6} x - 5[/tex]
Step-by-step explanation:
Given expression:
6x + 7y = -42
To find an equation perpendicular to this, it implies the slope must be a negative inverse of the given one.
Solution:
Equation of any straight line is given as;
y = mx + c
where x and y are the coordinates
m is the slope
c is the intercept
Let us now find the slope of the line;
6x + 7y = -42
7y = -6x - 42
divide through by 7 to give;
y = [tex]-\frac{6}{7} x[/tex] - 6
The slope is [tex]-\frac{6}{7}[/tex]
A line perpendicular will have a slope of a negative inverse;
- ( [tex]-\frac{7}{6}[/tex] ) = [tex]\frac{7}{6}[/tex]
The answer is A.

Answer:
BC = 14.40 correct to 1dp
Step-by-step explanation:
Sin44°= AC/BC
BC=AC/sin44°
BC=10/0.695
BC=14.3884892086330
BC = 14.40 correct to 1dp
Can you help with these two plz? Number a and b if you can do c and d for me that would be great as well!
Answer:
a) x = 60. b) b = 110. c) x = 20. d) x = 30.
Explanation:
For question a, 2x and 120° are opposite (vertical) angles so they must be the same measure according to the vertical angle theorem by definition, given they are angles formed by the transversal cutting two parallel lines. 2x = 120, so x = 60.
For question b, 130° and b + 20 are corresponding angles of the transversal cutting parallel lines, so they must be the same measure according to corresponding angle theorem(same side, one angle inner, and the other exterior of that) by definition. Given that they are both pairs of the same angle, they must be corresponding angles. 130° = b + 20, b = 110.
For question c, 120° and 2x + 20 are same side interior angles so they must be supplementary(add up to 180°) by definition. This is on the *same side* of the transversal inside the two parallel lines cut by it. 120° + 2x + 20° = 180°, x = 20°.
For question d, They are also on the same side but on the left so the same property of corresponding angles applies, so 3x + 10, and 100° must be the same measure. Therefore 3x + 10 = 100°, and x = 30.
solve the equation using the quadratic formula. 3v^2+3=-v
Answer:

Help Asap ! Find The Measure Of Angle A In The Triangle.
Answer: m<A = 35
Step-by-step explanation: The sum of the measures
of the interior angles of a triangle is 180°.
So we can setup the equation 3x + 5 + 8x + 65 = 180.
Combining our numbers and variables on the left, we have 11x + 70 = 180.
Now subtract 70 from both sides to get 11x = 110.
Dividing both sides by 11, we find that x = 10.
In the diagram, the m<A is represented as 3x + 5.
Plugging a 10 in for x, we have 3(10) + 5 or 30 + 5 which is 35.
So the m<A = 35.

A statistics teacher was interested in the relationship between the number of days students waited to start a project and the score that project received (out of 100 points). Information was collected on several students and was used to obtain the regression equation y = –3.64x + 96.5, where x represents the number of procrastination days and y is the predicted grade. What is the predicted grade of a student who procrastinated for 2 days?
25.96
85.58

103.78
Answer:
89.22
Step-by-step explanation:
just plug in 2 to the x in a calc like so: -3.64(2)+96.5 and it will give you 89.22 . got it right on my quiz like 5 min ago sooo yeah hope this helps people in the future.

4.5(8-x)+36=102-2.5(3x+24)
Answer: x= -10
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
4.5(8−x)+36=102−2.5(3x+24)
(4.5)(8)+(4.5)(−x)+36=102+(−2.5)(3x)+(−2.5)(24)(Distribute)
36+−4.5x+36=102+−7.5x+−60
(−4.5x)+(36+36)=(−7.5x)+(102+−60)(Combine Like Terms)
−4.5x+72=−7.5x+42
−4.5x+72=−7.5x+42
Step 2: Add 7.5x to both sides.
−4.5x+72+7.5x=−7.5x+42+7.5x
3x+72=42
Step 3: Subtract 72 from both sides.
3x+72−72=42−72
3x=−30

It is required to find the standard form.
What is arithmetic?Arithmetic is the branch of mathematics that deals with the study of numbers using various operations on them. Basic operations of math are addition, subtraction, multiplication and division. These operations are denoted by the given symbols.
Given:
According to given question we have,
The least common multiple of the fraction denominators is 6. Multiplying by that gives
16y = 5x -2
We can put this in standard form by adding 2-16y to both sides.
5x -16y = 2
Therefore, the standard form of the equation is 5x -16y = 2.

Question 6(Multiple Choice Worth 1 points) (02.05 MC) Choose the table that represents g(x) = 4⋅f(x) when f(x) = x − 5. x g(x) 1 −4 2 −3 3 −2 x g(x) 1 −16 2 −12 3 −8 x g(x) 1 −20 2 −18 3 −16 x g(x) 1 −1 2 −2 3 −3
Answer: (b)
x g(x)
1 -16
2 -12
3 -8
If g(x) is 4*f(x), then we can find g(x) by multiplying 4 by x-5
g(x) = 4(x-5)
= 4x-20
Now we can plug in 1,2, and 3 for x to see which table makes sense.
g(1) = 4(1) - 20
= -16
g(2) = 4(2) - 20
= -12
g(3) = 4(3) - 20
= -8

Maya and carlos was selling cookie dough for school fundraiser customers can buy packages of chocolate-chip cookie dough and packages of gingerbread cookie dough my sold 8 packages of chocolate chip cookie dough and 12 packages of gingerbread cookie dough for a total of $374 carlos o two packages of chocolate chip cookie dough and four packages of gingerbread cookie dough for a total of $113 final cost of one package of chocolate chip cookie dough and one package of gingerbread cookie dough
Answer:
Cost of chip cookies = $17.5
Cost of ginger cookies = $19.5
Step-by-step explanation:
Assume;
Cost of chip cookies = c
Cost of ginger cookies = g
So,
Maya's sales = 8c + 12g = 374 .....Eq1
Carlo's sales = 2c + 4g = 113 .......Eq2
4 x eq2
So
8c + 16g = 452......Eq3
Eq 3 - Eq 1
4g = 78
g = 19.5
and
c = 17.5
Cost of chip cookies = $17.5
Cost of ginger cookies = $19.5
