What is the slope-intercept equation of this line? A. y=-2x+6 B. y=2x+6 C.y=-1/2x+6 D.y=6x-2
Answer:
y = [tex]-\frac{4}{3}[/tex]x + 6
Step-by-step explanation:
y = mx + b
m: slope
b: y-intercept
y-intercept point on the graph is (0, 6) because it's the point that's on the y-axis.
Therefore, y-intercept is 6.
Slope: [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Point A: (0, 6)
Point B: (4, -2)
Slope (m) = [tex]\frac{-2 - 6}{4 - -2}[/tex]
[tex]m = \frac{-2 - 6}{4 +2}[/tex]
[tex]m = \frac{-8}{6}[/tex]
[tex]m = -\frac{4}{3}[/tex]
y = [tex]-\frac{4}{3}[/tex]x + 6

Evaluate the function if x=-3
f(x) =1/2x-1
A. -2.5
B. 0.5
C. -4
D. -1
Answer:
A) -2.5
Step-by-step explanation:
You have to plug the x-value into the function.
f(x) = (1/2)x - 1
f(x) = 1/2(-3) - 1
f(x) = (-3/2) - 1
f(x) = -1.5-1
f(x) = -2.5

Given p(x), find p(-1) by using synthetic substitution.
p(x)=7x^3-6x^2+39x-104
p(-1)= _______
Answer:
p (-1) = -156
Step-by-step explanation:
Explanation:-
Given polynomial
p(x)=7x³ -6x²+39x-104
Put x=-1
p (-1) = 7 ( -1 )³ - 6 ( -1 )² + 39 (-1 ) - 104
= - 7 - 6 - 39 - 104
p (-1) = -156
Mr. Gregson packs ornaments into boxes. Each box holds eight ornaments. Which representation displays the relationship between x, the number of boxes packed, and y, the number of ornaments packed?
Answer:
y = 8x
Step-by-step explanation:
Given that :
Ornanment are packed in boxes
Number of ornament per box = 8
x = number of boxes packed
y = Number of ornaments
Number of Ornanments packed = (Number ornaments per box * number of boxes packed
y = 8 * x
y = 8x

A jacket is on sale for $68.00. There is 5% sales tax on the purchase. What is the total cost, including tax?
Answer:
$71.40
Step-by-step explanation:
Before Tax Price: $68.00
Sale Tax: 5.00% or $3.40
After Tax Price: $71.40
Answer:
71.40
Step-by-step explanation:
Sales tax = 5% of 68
[tex]=\frac{5}{100}*68\\\\=\frac{340}{100}\\\\= 3.40[/tex]
Sales tax = $ 3.40
Total cost = 68 + 3.40 = $ 71.40
The best player on a basketball team makes 95% of all free throws. The second-best player makes 90% of all free throws. The third-best player makes 80% of all free throws. Based on their experimental probabilities, estimate the number of free throws each player will make in his or her next 40 attempts. Explain.
Answer: See explanation
Step-by-step explanation:
The best player on a basketball team makes 95% of all free throws. The number of free throws the best player will make in his or her next 40 attempts will be:
= 95% × 40
= 95/100 × 40
= 0.95 × 40
= 38
The second-best player makes 90% of all free throws. The number of free throws the best player will make in his or her next 40 attempts will be:
= 90% × 40
= 90/100 × 40
= 0.90 × 40
= 36
The third-best player makes 80% of all free throws. The number of free throws the best player will make in his or her next 40 attempts will be:
= 80% × 40
= 80/100 × 40
= 0.80 × 40
= 32

Write the equation of the line that passes through the point (1,5) and has a slope of -2.
Answer:
y = -2x + 7
Step-by-step explanation:
to write the equation to this problem, we need to find the the y intercept, or the point where the line intersects the Y axis
a slope of -2 means that for every x unit in the positive x direction (right) two y units are moved in the negative Y direction (downward)
so if we subtract (go to the left) 1x that means we would also have to add (go up) 2y, which would leave us at the point (0,7)
now, an equation for a line is written as Y = MX + B
M = slope
B = y intercept
our slope, as we said before, is -2, and we found the Y intercept, 7, so now we can construct our equation
y = -2x + 7
Answer:
y= -2x + 7

Step-by-step explanation:
most of the words like and are just fillers. and basically means together in this instance
1 point
When substituting y = 5x + 12 into the equation 3x - 2y - 32 = 0 to solve the
system, Jun determines that the value of y is
- a negative fraction only
- a positive fraction only
- a negative integer
- a positive integer
Answer:
A negative integer
Step-by-step explanation:
3x - 2(5x+12) - 32 = 0
3x - 10x - 24 - 32 = 0
-7x -56 = 0
-7x = 56, x = -8
y = 5(-8) + 12, y = -28

Use the zero product property to determine the x-intercepts for the graph of the quadratic function
1. y= -x squared -7x-12
2. y= 3x squared +11x+10
Answer:
1) x-intercepts are at -3 and -4
2) x-intercepts are at 5/3 and 2
Step-by-step explanation:
1) y = -x^2 - 7x - 12 is -(x + 3) (x + 4)
2) y = 3x^2 + 11x + 10 is (3x + 5) (x + 2)
A regular m-gon has 3 times as many sides as a regular k-gon.
The measure of an interior angle of the regular m-gon is 14/3 times
the measure of an exterior angle of the regular k-gon.
Algebraically find the values of k and m.
9514 1404 393
Answer:
k = 10m = 30Step-by-step explanation:
The interior angle of the m-gon is ...
m-interior = 180 -360/m
The exterior angle of the k-gon is ...
k-exterior = 360/k
The required relationships are ...
m = 3k
m-interior = 14/3(k-exterior)
Substituting for m, we can write the latter relation as ...
(180 -360/(3k)) = 14/3(360/k)
Multiplying by 3k/180, we have ...
3k -2 = 28
k = (28 +2)/3 = 10
The values of k and m are 10 and 30, respectively.
_____
Check
The interior angle of the m-gon is 180 -360/30 = 168 degrees.
The exterior angle of the k-gon is 360/10 = 36 degrees.
The angle ratio is 168/36 = 14/3 as required.
