The equation y+ 3 = 5(x - 3) represents a linear function. What is the y intercept of the equation?
Answers
Answer:
-18
Step-by-step explanation:
If you're looking for the y-intercept for this equation this means that x = 0.
So substitute x as 0 in the equation and you'll get the following.
y + 3 = 5 (0 - 3)
y + 3 = -15
y = -18

Answer:
C
Step-by-step explanation:
so solving the first one we get
y=2x+5
and the second one we get
y=5x+10+1
y=5x+11
substiuting we get
2x+5=5x+11
3x=-6
x=-2
and y= 1
so it would be C

can you help me solve the linear equation algebraically y=-x-3. y=-2x-8
Answers
Answer:
I can't it's to hard try studying
x=-5
y=2
Explanation:
Since both of these equations are equal to y, they have to be equal to each other. Set them equal to each other like this: -x-3= -2x-8. Multiply everything by negative 1 to get rid of the negative signs. The equation will look like this: x+3= 2x+8. Than subtract the x from both sides. Than subtract 8 from both sides. That should get you to x=-5. Than plug in -5 into the x value for one of the linear equations. It will get you 2 for the y.

Answers
Answer:
30° and 110°
55° and 85°
70°and 70°
Step-by-step explanation:
Given that :
Angle B = 40°
Sum of angles in a triangle :
Angle (A + B + C) = 180°
A + 40 + B = 180
A + C = 180 - 40
A + C = 140°
From the Given options ;
The sun of the Angles Given must add up to 140°
Hence,
30° and 110° = 140°
55° and 85° = 140°
70°and 70° = 140

The trend line passes through (10,9) and (35,0). Write an equation for the trend line.
Answers
Answer: Solution :
Step 1 :
Make a scatter plot of Lily’s running data.
Step 2 :
To draw a trend line, use a straight edge to draw a line that has about the same number of points above and below it. Ignore any outliers.
Step 3 :
Find the slope of the trend line.
The line passes through points (2, 20) and (4.5, 45).
Use the slope formula.
m = (y2 - y1) / (x2 - x1)
Substitute x1, = 2, y1 = 20, x2 = 4, and y2 = 45.
m = (45 - 20) / (4.5 - 2)
m = 25 / 2.5
m = 10
Step 4 :
Find the y-intercept of the trend line.
Slope-intercept form equation of a line :
y = mx + b
Plug y = 20, m = 10 and x = 2.
20 = 10 · 2 + b
20 = 20 + b
Subtract 20 from both sides.
0 = b
Step 5 :
Use your slope and y-intercept values to write the equation.
Slope-intercept form equation of a line :
y = 10x + 0
So, the equation for the trend line is
y = 10x
