Answer:
10100
Step-by-step explanation:
the sum of the first 100 even integers is equal to 10100.
Answer:
x = - 2
Step-by-step explanation:
(f + g)(x)
= f(x) + g(x)
= x² - 2x + 6x + 4
= x² + 4x + 4
Equating to zero
x² + 4x + 4 = 0
(x + 2)² = 0
x + 2 = 0
x = - 2
Answer:
4 2/ 7
Step-by-step explanation:
using a = a/1, convert the expression into fraction
5/1 x 6/7 to multiply the fractions, multiply the numerators and denominators separately
5x6/1x7 = 30/7 alternative form 4 2/7, 4.285714
Answer:
x=0. The explanation is below.
Step-by-step explanation:
So, it is run 2 rise 6. We can fact-check that with 1 to 3 to 5 and 1 to 7 to 13. So, the slope is 3 because of rise over run. So, we can make an equation with y = mx + b. m = 3 because that is the slope. 1=3(1) + b. b=-2. So, the equation is y=3x-2. We can find any x using y and vice versa if we find the equation.
For this part, -2=3x-2. 3x=0. x=0.
