Answer:
Option D: 2 is the correct answer.
Step-by-step explanation:
Given equation is:
2(x + 1) = 2x + ______
For balancing the equation, the variables and constants must be same on both sides of the equation.
Simplifying 2(x+1) gives us 2x+2
As 2x is already there, we will add 2 with it in the equation.
Hence,
Option D: 2 is the correct answer.
what's the ratio for 3 stars and 7 circles
Answer: 3:7
Step-by-step explanation:
There are 3 stars for every 7 circles, thus the ratio is 3:7.
Answer:
3 : 7.
Step-by-step explanation:
For every 3 stars, there are 7 circles. If 3 stars is written first, you'll need to write 3 first in your answer, and 7 second.
This is what it would look like: 3 : 7
With ratios, you could also write,
3 to 7
or
3 / 7
But 3 : 7 is most common :)
A line passes through the point (-8,-5) and has a slope of 3/4. Write an equation in slope intercept form for this line.
Answer:
y = ¾x + 1
Step-by-step explanation:
Point-slope equation for line of slope ¾ that passes through (-8,-5):
y+5 = ¾(x+8)
Put into slope-intercept form:
y = ¾(x+8) - 5 = ¾x + 6 - 5 = ¾x + 1
Place parentheses in the expression so that it equals the given value.
20 + 2 x 5 + 4^1
Value: 38
Select the correct answer.
What are the slope and the y-intercept of the line of best fit on this scatter plot?
Answer:
A
Step-by-step explanation:
slope is change in y over change in x, line goes down 4, right three whole units, making the slope -4/3
y-intercept is where the line hits the y-axis
the line hits the y-axis at (0,8)
this makes the y-intercept 8
Answer:
The y-intercept is 8 , and the slope is -4/3.

given that the line y/2 = x-p passes through the point ( -4 , 4 ) , then the value of " p " is ?
Answer:
-6
Step-by-step explanation:
Given,
(-4,4)=(x,y)
y/2=x-p
Substituting the value of(x,y) in the given line,
4/2= -4-p
or,2= -4-p
or,2+4= -p
or,-p= 6
hence,p = -6

LCM of 189024
please give me answer my question
Answer:
360
Step-by-step explanation:
We need to find the LCM of 18,90 and 24.
The prime factorization of 18 = 2 × 3 × 3
The prime factorization of 90 = 2 × 5×3×3
The prime factorization of 24 = 2 × 3×2×2
LCM is least common multiple.
LCM = 2 x 2 x 2 x 3 x 3 x 5
= 360
Hence, the LCM of 18,90 and 24 is 360.

6) a pizza is divided among John, Tim and kevon . John received 3/8 and Tim received 1/3 of the remainder. What fraction does Kevon receive? (A) 5/8 (B) 9/24 (C) 5/24 (D) 10/24
Answer:
C. 5/24
Step-by-step explanation:
John = 3/8
Tim = 1/3
Kevon = ?
---------------------------------
3/8 = 0.375
1/3 = 0.333
0.375 + 0.333 = 0.708
0.292 is left
---------------------------------
5/8 = 0.625 - wrong
9/24 = 0.375 - wrong
5/24 = 0.208333 = 0.293
10/24 = 0.416667 - wrong

Find the equation for the circle with center (3,−5) and diameter of length 8.
Answer:
(x-3)² + (y+5)² = 16
Step-by-step explanation:
Radius will be half of diameter means that radius = r = 8/2 = 4.
With Center (h,k) the equation of circle is
(x-h)² + (y-k)² = r²
so by putting values answer will be
(x-3)² + (y+5)² = 4²
(x-3)² + (y+5)² = 16

A sphere is a three-dimensional geometric figure, hollow or solid, contained by a continuously round surface that is equidistant from its center. The maximum capacity of a sphere is calculated with the formula, where V = volume, and r = radius. For a sphere with a maximum capacity of 1,372pi/3 cubic millimeters, the diameter measures millimeters.
Answer:
14 millimeters
Step-by-step explanation:
V=(4/3)πr³
1372π(1/3)=(4/3)πr³
1372=4r³ (cancel out the pi and multiply both sides by 3)
r³=343
r=7
Diameter is twice the radius = 2(7) = 14
What is the value of x^6+y^2x 6 +y 2 x, start superscript, 6, end superscript, plus, y, squared when x=1x=1x, equals, 1 and y=11y=11y, equals, 11?
Try 122.
Step-by-step explanation:
Since x = 1, x^6 = 1.
Since y = 11, 11^2 = 121.
1 + 121 = 122.
So, the value of x ^ 6 + y ^ 2 = 122.Answer:82
