Answer:
125
Step-by-step explanation:
The two angles are supplementary which means their sum is equal to 180 degrees
180 - 55 = 125 is the measure of the unknown angle.
Answer:
x=-3
Step-by-step explanation:
Answer choice A is a vertical line through the the x-axis crossing through -3. It has an x-intercept of -3.
Answer choice B is a horizontal line through the y-axis crossing through -3. It has no x-intercpet.
Answer choice C is a horizontal line through the y-axis crossing through 7. It has no x-intercept.
Only A has an x-intercept of -3.
Answer:
can you give us the expression, please? we'll try to answer it ! but first you need to give us something to work with ':)
First, rearrange the quadratic equation:
5x² + 9x - 4 = 0
Now, compare it to the general quadratic equation:
a<span>x² + bx + c = 0
Therefore you get:
a = +5
b = +9
c = -4
And the quadratic formula will be:
x = [-b +/- </span>√(b² - 4ac)] / 2a
= [ -5 +/- √(81 - 4·5·(-4))] / 2·5
= (-5 +/- √161) / 10
Answer:
130 N/cm2
Step-by-step explanation:
7.8 cm2 -> 50N/cm2
3 cm2 -> x N/cm2
x = (50×7.8) / 3
x = 130N/cm2
