Answer:
7m-3x-1
10x+26
7x-12
Step-by-step explanation:
3m - 1 + 4m -3x
sum terms by the same variable:
3m+4m=7m
we have:
7m-3x-1
7(3+2x)-4x+5
apply the distributive property:
7*3+7*2x-4x+5
we have:
10x+26
3x+4(x-3)
apply the distributive property:
3x+4*x-12
we have:
7x-12
Answer:
5.
Step-by-step explanation:
2[(8−4)5/8]
= 2[4*5 / 8]
= 2 * 2.5
= 5.
Answer:
y = -3.5x + 15
Step-by-step explanation:
Your slope-intercept equation is always y = mx + b
Using this formula, we need to find slope first: m = (y2-y1) / (x2-x1)
Step 1: Find slope
m = (1-8) / (4-2)
m = -7/2
Step 2: Plug in into slope-intercept form
y = -3.5x + b
Step 3: Find <em>b </em>(Plug in a coordinate given)
1 = -3.5(4) + b
1 = -14 + b
b = 15
Step 4: Combine it all together
y = -3.5x + 15
And you have your final answer.
Answer:
x = 4.45 or x = - 4.45
Step-by-step explanation:
Here are the steps:
Substitute the values,
÷ 2 × 1
x = 2 ± √6
x = 4.45 or x = - 4.45
