Answer: c
Step-by-step explanation:
X+y=70
x=2y-5
x=larger number
y=smaller number
now plug in the value of x to only have one variable in the equation...
Way to solve for y:
(2y-5)+y=70
3y-5=70
add 5 on both sides...
3y=75
divide by 3 on both sides
y=25
1st way to solve for x:
now plug in y in the original equation...
x+25=70
subtract 25 on both sides...
x=45
2nd way to solve for x:
plug in y for the second equation...
x=25(2)-5
x=50-5
x=45
answer: the two numbers are 45 and 25.
Answer:
Yes, it is a graph
Step-by-step explanation:
Answer:
95°
Step-by-step explanation:
(x+49)+(x+59)=180
2x+108=180
2x=72
x=36
36+59=95
x^2 + 2x + 8
First, we'll try using the AC method.
(Because the degree of the quadratic is 2, there are two solutions.)
We cannot split the term using the AC method.
We'll instead use the quadratic formula.
Plug in values.
(-2 +/- √4 - 32)/2
(-2 +/- √-28)/2
(-2 +/- i√28)/2
(-2 +/- 2i√7)/2
(-1 +/- i√7)
<h3>x = (-1 + i√7)</h3><h3>x = (-1 - i√7)</h3><h3>The two values of x are found.</h3>
