Answer:
x = 30
Step-by-step explanation:
All the angles on a point add up to 360°. Thus, you can find 2x easily.
2x = 360° - 300°
= 60
x = 60 ÷ 2
= 30
Answer:
x = 23
Step-by-step explanation:
Remember, angles in a triangle add up to equal 180
That being said we can create an equation to solve for x
180 = 110 + 35 + x + 12
now we solve for x
step 1: combine like terms
110 + 35 + 12 = 157
now we have 180 = 157 + x
step 2 subtract 157 from each side
180 - 157 = 23
157 - 157 cancels out
we're left with x = 23
Slope of the line is -4/5, y-intercept is 3, equation in slope-intercept form is y = -4/5 x + 3 and the x-intercept is 15/4
Step-by-step explanation:
Slope = (y2 - y1)/(x2 - x1)
Here, x1 = 0, y1 = 3, x2 = 5, y2 = -1 (based on the plotted points)
⇒ m = (-1 - 3)/(5 - 0) = -4/5
- Step 2: Find the y-intercept
y-intercept is the point where the line intersects the y-axis.
Here, the y-intercept, b = 3
- Step 3: Write the equation of the line in slope-intercept form
y = mx + b ⇒ y = -4/5 x + 3
- Step 4: Find the x-intercept using the equation.
x-intercept is the point where the line intersects the x-axis. Then y = 0
⇒ 0 = -4/5 × x + 3
⇒ -4/5 × x = -3
⇒4x = 15
∴ x = 15/4
I asked Siri here’s the answer
Answer:
B)
Step-by-step explanation:
(2x^3+x^2-4x)-(9x^3-3x^2)
