a.3y = 2
b.7y = 6
c.11y = 16
d.4y = 16
Answer:
The Answer is A. 3y=2
Step-by-step explanation:
1) combine like terms
7y + 7 = 9 + 2y + 2y
7y +7 = 9 + 4y
Subtract 4y on both sides
3y +7 = 9
Subtract 7 on both sides
3y = 2 because 9 - 7 = 2

A person sitting in the top row of the bleachers at a sporting event drops a pair of sunglasses from height of 24 feet. the function h= -16X squared + 24 represents the height h ( in feet) of the sunglasses after x seconds. how long does it takes the sunglasses to hit the ground.) please someone help me I will mark Brainliest
Answer: square root of 3/2 seconds
Step-by-step explanation:
h=-16x²+24
Set the height to be 0
0=-16x²+24
-24=-16x²
24=16x²
24/16=x²
x²=3/2
x= square root of 3/2
you have to set the equation equal to 0 to represent when it hits the ground
0=-16x²+24
-24=-16x²
-24/16=x² --> -3/2=x²
x=-1.22474

Answer:
Draw a line. Label one endpoint M and the other P. Go half way between the two and label it O.
34z = 36z - 7
MO = 119
Step-by-step explanation:
A line segment with a midpoint means the segment has been divided into two equal segments. This means each segment is equal to the other OM = OP.
You can solve for z by setting them equal to each other.
34z = 36z - 7
-2z = -7
z = 7/2
To find MO, substitute z = 7/2 into the equation OM = 34z.
OM = 34(7/2) = 238/2 = 119

describe the nature of the roots for this equation.
3x^2 - 2x + 1 = 0
A. two real, rational roots
B. two real, irrational roots
C. one real, double root
D. two complex roots
Answer:
Option D. two complex roots
Step-by-step explanation:
we know that
In a quadratic equation of the form [tex]ax^{2} +bx+c=0[/tex] the discriminant D is equal to
[tex]D=(b^{2}-4ac)[/tex]
in this problem we have
[tex]3x^{2} -2x+1=0[/tex]
so
[tex]a=3\\b=-2\\c=1[/tex]
substitute the values
[tex]D=(-2^{2}-4(3)(1))[/tex]
[tex]D=(4-12)[/tex]
[tex]D=-8[/tex]
The discriminant is negative
therefore
The quadratic equation has two complex roots
Final answer:
The equation 3x² - 2x + 1 = 0 has a negative discriminant of -8, indicating that it does not have real roots but instead has two complex roots.Therefore, the correct answer is D. two complex roots.
Explanation:
To determine the nature of the roots for the equation 3x²- 2x + 1 = 0, we need to calculate the discriminant, which is given by b² - 4ac. Here, a = 3, b = -2, and c = 1. Substituting these values into the discriminant formula gives us (-2)² - 4(3)(1) = 4 - 12 = -8. Since the discriminant is negative, the equation does not have real roots. Instead, it has two complex roots.
Therefore, the correct answer is D. two complex roots.

Write an equation for the circle with a center of (5, -2) and a radius of 3.
Answer:
(x - 5)² + (y + 2)² = 9
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
here (h, k) = (5, - 2) and r = 3, thus
(x - 5)² + (y - (- 2))² = 3², that is
(x - 5)² + (y + 2)² = 9 ← equation of circle

1. Find the shaded area of each figure, round your answer to one decimal place if necessary.
Answer:
Part a) [tex]114.3\ yd^{2}[/tex]
Part b) [tex]49.5\ yd^{2}[/tex]
Step-by-step explanation:
Part a) we know that
The area of the shaded figure is equal to the area of semicircle plus the area of a triangle
Find the area of semicircle
The area of a semicircle is equal to
[tex]A=\frac{1}{2}\pi r^{2}[/tex]
we have
[tex]r=5\ yd[/tex]
substitute
[tex]A=\frac{1}{2}\pi (5)^{2}=12.5 \pi\ yd^{2}[/tex]
Find the area of triangle
The area of the triangle is equal to
[tex]A=\frac{1}{2}(b)(h)[/tex]
we have
[tex]b=15\ yd[/tex]
[tex]h=5(2)=10\ yd[/tex] -----> the height of triangle is equal to the diameter of semicircle
substitute
[tex]A=\frac{1}{2}(15)(10)=75\ yd^{2}[/tex]
Find the area of the shaded figure
[tex]12.5 \pi\ yd^{2}+75\ yd^{2}=(12.5 \pi+75)\ yd^{2}[/tex]
assume
[tex]\pi=3.14[/tex]
[tex](12.5(3.14)+75)=114.3\ yd^{2}[/tex]
Part b) we know that
The area of the shaded figure is equal to the area of the triangle minus the area of the circle
Find the area of the circle
The area of the circle is equal to
[tex]A=\pi r^{2}[/tex]
we have
[tex]r=5\ yd[/tex]
substitute
[tex]A=\pi (5)^{2}=25 \pi\ yd^{2}[/tex]
Find the area of triangle
The area of the triangle is equal to
[tex]A=\frac{1}{2}(b)(h)[/tex]
we have
[tex]b=16\ yd[/tex]
[tex]h=16\ yd[/tex]
substitute
[tex]A=\frac{1}{2}(16)(16)=128\ yd^{2}[/tex]
Find the area of the shaded figure
[tex]128\ yd^{2}-25 \pi\ yd^{2}=(128-25 \pi)\ yd^{2}[/tex]
assume
[tex]\pi=3.14[/tex]
[tex](128-25(3.14))=49.5\ yd^{2}[/tex]
a) The area of the shaded figure [tex]114.3yd^{2}[/tex]
b) The area of the shaded figure=[tex]49.5yd^{2}[/tex]
How can the shaded area be calculated?Part a) The area of the shaded figure= (the area of semicircle)+ (the area of a triangle)
Area of semicircle= [tex]A=\frac{\pi r^{2} }{2}[/tex] where r = radius = 5
[tex]A=\frac{\pi 5^{2} }{2} =39.3 yd^{2}[/tex]
The area of the triangle= [tex]\frac{1}{2} base *height[/tex]
base = 15
height=10
The area of the triangle= [tex]\frac{1}{2}*15 *10 =75 yd^{2}[/tex]
The area of the shaded figure=39.3+75= [tex]114.3yd^{2}[/tex]
Part b) The area of the shaded figure =( the area of the triangle) -(area of the circle)
The area of the triangle=[tex]\frac{1}{2} base *height[/tex]
base and height = 16
Area=[tex]\frac{1}{2} *16*16=128yd^{2}[/tex]
The area of the circle=[tex]\pi r^{2} =3.142*5^{2} = 78.55 yd^{2}[/tex]
[tex]128 yd^{2} -78.55 yd^{2} =49.5yd^{2}[/tex]

Polygon q is a scaled copy of polygon p using a scale factor of 1/2 polygon q’s area is what fraction of polygon p’s area?
Answer:
Polygon q’s area is one fourth of polygon p’s area
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its areas is equal to the scale factor squared
Let
z-----> the scale factor
x-----> polygon q’s area
y-----> polygon p’s area
so
[tex]z^{2} =\frac{x}{y}[/tex]
In this problem we have
[tex]z=\frac{1}{2}[/tex]
substitute

Answer:
x=3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
2(2x−17)+4=−3(3+x)
4x+−34+4=−9+−3x {distribute}
4x+−30=−3x−9 {combine like terms}
Step 2: Add 3x to both sides.
4x−30+3x=−3x−9+3x
7x−30=−9
Step 3: Add 30 to both sides.
7x−30+30=−9+30
7x=21
Step 4: Divide both sides by 7.
7x/7=21/7
x=3
4x - 3x = -9 + 30 2 (2x - 17) + 4 = -3 (3 + x)
So, we are going to DISTRIBUTE
Lets work on the left side of the equation first
Multiply 2 on the out side of the parenthesis by what is on the inside
2 x 2x = 4x
2 x -17 = -34
So on the left side we now have
4x - 34 + 4
add 4
4x - 30
Let's do the same thing on the other side
-3 x 3 = -9
-3 x X = 3x
Now let's put everything together
4x - 30 = -9 + 3x

solve using the addition method. what is the x-value of the solution to the system? 2x-3y=-1 3x+4y=24
Answer:
x-value is 4
Step-by-step explanation:
2x-3y=-1
3x+4y=24
We can solve the equation by eliminating y
We multiply the first equation by 4 and the second by 3
4(2x-3y=-1 )
3(3x+4y=24)
8x -12y = -4
9x +12y = 72
Then we add the two equations;
8x -12y = -4
9x +12y = 72
17x = 68
x = 4
Thus the x-value is 4
