Answer:
-7 3/4 (or it can be written as -31/4, an improper fraction)
Step-by-step explanation:
[tex]\left(\frac{1}{2}\right)^2-6\left(2-\frac{2}{3}\right)[/tex] [tex]\frac{1}{4} - 6(2-\frac{2}{3})[/tex] [tex]\frac{1}{4}-6(1\frac{1}{3})[/tex] [tex]\frac{1}{4} - 6 * \frac{4}{3}[/tex] [tex]\frac{1}{4} - \frac{24}{3}[/tex] [tex]\frac{1}{4} - 8[/tex] [tex]\frac{-31}{4}[/tex] [tex]-7\frac{3}{4}[/tex]Therefore, the answer is -7 3/4 as a mixed number and -31/4 as an improper fraction (they're the same thing).

Write the equation of the line through
(0, 4) and (2, 0) in slope-intercept form.
Answers
Answer: y = -2x + 4
Step-by-step explanation: slope intercept form is "y=mx+b" where m is the slope and b is they y intercept. the y intercept is when x=0 and it's given to us in the question. the y intercept is (0,4). so y=4. we can plug that into the equation to now have y=mx + 4.
now we need to find the slope. we can do this by plugging the two points into the formula [tex]\frac{y2-y1}{x2-x1}[/tex]. so we'd have [tex]\frac{0-4}{2-0}[/tex] to get -4/2 which is -2. -2 is the slope.
so the final answer is y = -2x + 4

Please help give the smaller and bigger angle measure
Answers
Answer:
Step-by-step explanation:
2 angles are supplementary if their sum is 180 degrees. The larger angle measures eight degrees more than three times the measure of a smaller angle. If x represents the measure of the smaller angle and these two angles are supplementary, find the measure of each angle. I have the answer but do not know how to get it 43 degrees & 137 degrees
Let the smaller angle be x
The larger angle will be 3x+8
X+3x+8=180
4x=180-8=172
X=172/4
X=43
3*43+8= 137

On Monday, 4 x 10 to the power of 2 people went to Fun World Amusement Park. On Tuesday, there were 3 x 10 to the power of 6 patrons at the amusement park. How many times larger was Tuesday's attendance than Monday's ?
Answers
The Monday and Tuesday attendance are illustrations of proportions.
Tuesday's attendance is larger than Monday's 7500
The given parameters are:
[tex]\mathbf{Monday = 4 \times 10^2}[/tex]
[tex]\mathbf{Tuesday = 3 \times 10^6}[/tex]
The number of times (n) the Tuesday attendance is larger than Monday's is:
[tex]\mathbf{n = \frac{Tuesday}{Monday}}[/tex]
So, we have:
[tex]\mathbf{n = \frac{3 \times 10^6}{4 \times 10^2}}[/tex]
[tex]\mathbf{n = 0.75 \times 10^{6-2}}[/tex]
[tex]\mathbf{n = 0.75 \times 10^{4}}[/tex]
[tex]\mathbf{n = 7500}[/tex]
Hence, Tuesday's attendance is larger than Monday's 7500

In 20 seconds, a roller coaster goes up a 100-meter hill, then down 72 meters, and then back up a 48-meter rise. What integer represents the vertical change from the start of the ride for the coaster after the 20 seconds?
Answers
The question is an illustration of arithmetic operations.
The integer that represents the vertical rise is 76
Upward movements are represented with positive, while downward movements are represented with negative.
So, the given parameters are:
[tex]Up = 100m[/tex]
[tex]Down = -72m[/tex]
[tex]Up= 48m[/tex]
The vertical rise is:
[tex]Rise = Up_1 + Down + Up_2[/tex]
So, we have:
[tex]Rise = 100m -72m +48m[/tex]
[tex]Rise = 76m[/tex]
Hence, the integer that represents the vertical rise is 76

Answers
Answer:
a) 60° b) 50°
Step-by-step explanation:
The measurements of a triangles total angles is always equal to 180.
In question a), an Equilateral triangle is shown. Which means all the sides and angles are equal. So you divide 180 by 3, which equals 60.
In question b), an Isoceles triangle is shown. Which means two of the three sides and angles are equal. The other angle is already given: 80.
All you need to do now is subtract 80 from 180 and divide the diffrence by 2.
So, 180-80=100
100/2=50
S=50
Q=50

Find the value of x.
A) 870
C) 127°
E) 66°
B) 106°
D) 100°
Answers
Answer:
100
Step-by-step explanation:
y + 140 = 180 {Linear pair}
y = 180 - 140
y = 40
Given triangle is an isosceles triangle.
x + y + y = 180 {angle sum property of triangle}
x +2y = 180
x +2*40 = 180
x + 80 = 180
x = 180 - 80
x = 100
5. Rewrite the quadratic funtion from standard form to vertex form.
Ax) = 2x2 + 8x + 70
Answers
Answer:
[tex]y = 2 {(x + 2)}^{2} + 62[/tex]
Step-by-step explanation:
vertex form is
[tex]y = a {(x - h)}^{2} + k \\ where \: (h. \: k) \: is \: the \: vertex[/tex]
our original equation
[tex]2 {x}^{2} + 8x + 70[/tex]
first we will find the x value using the formula
[tex]x = - \frac{b}{2a} \\ - \frac{8}{2(2)} = - \frac{8}{4} = - 2 \\ x = - 2 = h[/tex]
plug the value of x back into the original equation to solve for y
[tex]y = 2 {x}^{2} + 8x + 70 \\ y = 2 ({ - 2}^{2} ) + 8( - 2) + 70 \\ y = 2(4) - 16 + 70 \\ y = 8 - 16 + 70 \\ y = 78 - 16 \\ y = 62 = k[/tex]
substitute this back into our vertex form and not forgetting the coefficient a = 2
[tex]y = 2 {(x - ( -2))}^{2} + 62 \\ y = 2 {(x + 2)}^{2} + 62[/tex]

Find the reciprocal of the divisor
Reciprocal of 6/7: 7/6
Now, multiply it with the dividend
So, 9/14 divided by 6/7 = 9/14 x 7/6

The division of the fraction 6/7 by 9/15 gives the result 4/3.
To simplify the division of 6/7 divided by 9/14, multiply the first fraction by the reciprocal of the second fraction.
The reciprocal of a fraction is obtained by swapping the numerator and the denominator.
So, the reciprocal of 9/14 is 14/9.
Now, rewrite the division as multiplication:
(6/7) * (14/9)
To multiply fractions, multiply the numerators together and the denominators together:
= (6 * 14) / (7 * 9)
= 84/63
Now, divide the numerator and denominator by their greatest common divisor, which is 21:
= (84/21) / (63/21)
= 4/3
Therefore, 6/7 divided by 9/14 simplifies to 4/3.

A kindergarten teacher bought $21 worth of stickers and cardstock for his class. The stickers cost $1.50 a sheet and the cardstock cost $3.50 per pack. The equation LaTeX: 1.5s+3.5c=21 represents the relationship between sheets of stickers, LaTeX: s, packs of cardstocks, LaTeX: c, and the dollar amount a kindergarten teacher spent on these supplies.
Answers
Answer:
Done
Step-by-step explanation:
Teacher bought $21 worth of stickers and cardstock for his class.
Cost of stickers = $1.50 per sheet
Cost of 's' sheets = $1.5s
Cost of cardstock = $3.50 per pack
Cost of 'c' packs = $3.5c
Equation representing the relationship between sheet of stickers and packs of cardstocks will be,
1.5s + 3.5c = 21
3.5c = -1.5s + 21
1).
y-intercept of the line → (0, 6)
x-intercept of the line → (14, 0)
Therefore, equation of the line represents the line on the graph.
2). Vertical intercept (0, 6) represents that he can purchase maximum 6 packs of cardstock with $21.
Similarly, horizontal intercept (14, 0) represents that he can purchase maximum 14 sheets of stickers with $21.
