Answer:
7.8 i
Step-by-step explanation:
Since -61 is negative, you simply do the square root of positive 61 and add an i (imaginary) so signify that it's negative.
1) y = -2x + 7
2) y = -2x + 11
3) y = 2x-9
4) y = 2x + 3
Answer:
Step-by-step explanation:
y - 5 = -2(x - 1)
y - 5 = -2x + 2
y = -2x + 7
Option 1 is the answer
Answer:
-16
Step-by-step explanation:
-17+25+-6-18
you just basically combined -17,-6 and -18
so -41+25
= -16
B. y = x2 − 5 y = −x − 1
C. y = x2 + 5 y = −x + 1
D. y = x2 + 5 y = −x − 1
Answer:
Option (A)
Step-by-step explanation:
For equation of the line,
Let the equation is, y = mx + b
Slope 'm' of the line passing through two points (-3, 4) and (2, -1),
m =
=
= -1
y-intercept of this line, b = 1
Now we substitute these values in the equation,
y = -x + 1
Let the equation of the parabola is,
y = a(x - h)² + k
Here, (h, k) is the vertex of the parabola,
Since vertex of the given parabola is (0, -5),
then the equation will be,
y = a(x - 0)²- 5
y = ax² - 5
Since a point (2, -1) lies on this parabola,
-1 = a(2)² - 5
5 - 1 = 4a
a = 1
Equation of the parabola will be,
y = x² - 5
Therefore, Option (A) will be the answer.
The missing percentage of the given algebraic expression when calculated is; 15.18%
We want to find;
Percent * $3.32 = $0.32 + $0.184
First of all, let us add the terms on the right side of the equation to get;
Percent* $3.32 = $0.504
Next operation is to divide both sides by 3.32 using division property of equality to get;
Percent = 0.1518 = 15.18%

Answer:
-2
Step-by-step explanation:
-15+7y=-25+2y
7y-2y=-25+15
5y= -10
5y/5= -10/5
y= -2
Answer:
y= -17/5 or -3.4
Step-by-step explanation:
-8+7y= -25+2y
5y= -17
y= -17/5 or -3.4
