Answer:
Step-by-step explanation:
Let x be the value of the test score needed to get 85
Equation
(77 + 89 + 78 + x)/4 = 85 Combine the left side to like terms
(244 + x)/4 = 85 Multiply by 4
244 + x = 85 * 4
244 + x = 340 Subtract 244
x = 340 - 244
x = 96
He needs to get 96 to average out to 85

Angles X and Y are supplementary. Angle X is 3 times the measure of angle Y. What is the measure of angle X?
45°
60°
120°
135°
Answer:
135 degrees
Step-by-step explanation:
135 is 3 times the measure of 45, and 45 + 135 equals 180. Supplementary angles add up to 180 degrees.

$482.56 divided by 8
Answer:
your answer would be $60.32
Add 19 to ‘a’ and divide the sum by 5, you will get 8
Answer:
a = 21
Step-by-step explanation:
Given
[tex]\frac{a+19}{5}[/tex] = 8 ( multiply both sides by 5 to clear the fraction )
a + 19 = 40 ( subtract 19 from both sides )
a = 21

what is the range of the function f(x)=-8x+13 when the domain is (-2,0,3)?
Answer:
The complete set of domain (x) and range values (y) is given by:
x y
-2 39
0 13
3 11
Step-by-step explanation:
Considering the function
[tex]f(x)=-8x+13[/tex]
As we know that the range of a function consists of the entire set of all possible resulting values of the dependent variable commanly called y or f(x), once we have substituted the domain.
Now
As the x values are -2, 0, and 3. So, the domain interval is (-2,0,3).Putting x = -2 in f(x) to determine the range for the value x = -2
[tex]f(x)=-8x+13[/tex]
[tex]f(-2)=-8(-2)+13=16+13=39[/tex]
Putting x = 0 in f(x) determine the range for the value x = 0
[tex]f(x)=-8x+13[/tex]
[tex]f(0)=-8(0)+13=0+13=13[/tex]
Putting x = 0 in f(x) determine the range for the value x = 3
[tex]f(x)=-8x+13[/tex]
[tex]f(3)=-8(3)+13=-24+13=11[/tex]
Therefore, the complete set of domain (x) and range values (y) is given by:
x y
-2 39
0 13

In the seventh grade, Rachel read 15 books.
In the eighth grade, she read 18 books.
Determine the percent of increase in the
number of books Rachel read.
Answer:
20%
Step-by-step explanation:
Calculate percentage change
from V1 = 15 to V2 = 18
(V2−V1)|V1|×100
=(18−15)|15|×100
=315×100
=0.2×100
=20%change
=20%increase

Find the distance between the points (-4,-2) and (4,3)
Answer:
9.433981132
Step-by-step explanation:
To learn how to find the distance between two points by using the distance formula, which is an application of the Pythagorean theorem. We can rewrite the Pythagorean theorem as d=√((x_2-x_1)²+(y_2-y_1)²) to find the distance between any two points, and I used my calculator to do so.

If 5 + 6i is a root of the polynomial function f(x), which of the following must also be a root of f(x)?
Answer:
5-6i
Step-by-step explanation:
The complex conjugate root theorem states that if (a+bi) is a root, then (a-bi) must also be a root and vice versa.
We know that (5+6i) is a root.
Then by the above theorem, (5-6i) must also be a root.
Hence, our solution is (5-6i).
The answer is (B).

2b-m=5 what is the solution for m
Answer:
m = -5 + 2b
Step-by-step explanation:

May I Have brainliest?
Which option? Help would be appreciated greatly
Answer:
Option 4: 6^7
Step-by-step explanation:
The rule is that when multiplying same bases with different exponents, the exponents only get added.
In other words, (x^a)(x^b)=x^(a+b)
In this case, (6^3)(6^4)=6^(3+4)=6^7
Therefore, Option 4 is correct

Brad’s checking account starts off with a balance of $126.50. Throughout the week, Brad pays a bill for $87.21 and pays $5.64 for breakfast. He deposits $15.00 but then pays another bill for $55.25. At the end of the week, he gets a notice from the bank that he has a negative balance. How much does Brad need to deposit into his account to get to a $0 balance?
Answer:
$6.60
Step-by-step explanation:
Answer:
$6.6
Step-by-step explanation:
We add the amount he paid,
($87.21 + $5.64) - $15.00 + 55.25
We will get ,
$92.85 - $15.00 + $55.25
Then,
$77.85 + $55.25
We will get,
$133.10, the subtract the $133.10 from his original balance and get
$126.50 - $133.10 = $-6.6
He will need to deposit $6.6 to get his account to $0 balance
