In a quiz consist of 10 questions,+2 marks are given for a correct answer, -1 marks for an incorrect answer and 0 marks for not attempting a question. Radhika got 8 correct answers and 2 wrong answers. What is her total score?
Answers
======================================================
Work Shown:
c = number of correct answers
w = number of wrong answers
n = number of questions not attempted
2c = points you get from all the correct answers
-1w = points you get from all the wrong answers
0n = points you get from all the questions attempted
2c-1w+0n = 2c-w = total number of points
In this case, she got 8 correct answers and 2 wrong answers. So c = 8 and w = 2 which leads to
2c-w = 2*8-2 = 16-2 = 14
Her total score is 14.

Solve for v
-39v=4v+7(v+7)
Answers
Answer:
-49/50
Step-by-step explanation:
-39v=4v+7(v+7)
Distribute
-39v = 4v +7v+49
Combine like terms
-39v = 11v+49
Subtract 11 v from each side
-39v-11v = 11v-11v +49
-50v = 49
Divide by -50
-50v/-50 = 49/-50
v = -49/50
Answer:
v= - 49/50
Step-by-step explanation:
-39v=4v+7(v+7)
open the parentheses by multiplying both v&7 by 7:
-39v=4v+7v+49
add like terms:
-39v-4v-7v=49
-50v=49
divide both sides by -50:
v= - 49/50
Write an equation in slope-intercept form of the line that passes through the given point and is parallel to the graph of the given equation.
(-3,-3);y=-3x-2 y=−3x+2
Write an equation for the line in slope-intercept form.
Answers
Answer:
y = –3x – 6
Step-by-step explanation:
We'll begin by obtaining the slope of the equation y = –3x – 2.
This can be obtained by comparing
y = –3x – 2 with y = mx + c
Thus, the slope (m) of the equation
y = –3x – 2 is –3.
Next, we shall determine the slope of the equation parallel to line with equation y = –3x – 2.
This is illustrated below:
For parallel lines, the slope are related as follow:
m1 = m2
m1 = –3
m2 = m1 = –3.
Finally, we shall determine the equation as follow:
Coordinate = (–3, –3)
x1 coordinate = –3
y1 coordinate = –3
Slope (m) = –3
y –y1 = m(x – x1)
y – (–3) = –3 (x – (–3))
y + 3 = –3 (x + 3)
y + 3 = –3x – 3
Rearrange
y = –3x – 3 – 3
y = –3x – 6
Thus, the equation parallel to the line is y = –3x – 6
Bart earns $6.30 per h. If his regular pay last week was $236.25, how many hours did he work?
Answers
Answer:
Bart worked 37.5 hours last week (37 1/2).
Step-by-step explanation: Divide total pay by rate per hour (in this case $6.30 per hour.)
$236.25 (the total) / $6.30 (money per hour) = 37.5 or 37 1/2

Answers
See attachment for math work and answer.
a) The expression will be zero when x = -4 or 8
b) The trinomial equivalent of the expression is x² - 4x - 32
c) The trinomial equals to zero when x = 8
The given expression is (x - 8)(x + 4)
a) For what value of x will the expression be equal to zero
(x - 8)(x + 4) = 0
This can be split into:
x - 8 = 0
That is, x = 8
x + 4 = 0
That is, x = -4
The expression (x - 8)(x + 4) equals to zero when x = -4 or x = 8
b) Write this product as an equivalent trinomial.
A trinomial is a polynomial expression with three terms
Expand (x - 8)(x + 4)
x² + 4x - 8x - 32
x² - 4x - 32
c) Show that this trinomial is also equal to zero at the larger value of x from part (a)
The larger value of x from part (a) is 8
Substitute x = 8 into x² - 4x - 32
8² - 4(8) - 32
= 64 - 32 - 32
= 0

Answer: 52
Step-by-step explanation:
4x+8 = 5x-3 by the Vertical Angles Theorem that states the vertical angles are congruent.
Subtract 4x from both sides and get:
8=1x -3
Add 3 to both sides:
11= 1x
if x =11, plug that in to angle A.
4x+ 8 becomes 4(11)+8 =
