Answer:
C
Step-by-step explanation:
Note that (f + g)(x) = f(x) + g(x)
f(x) + g(x)
= 4x + 1 + x² - 5 ← collect like terms
= x² + 4x - 4 → C
Answer: x=-4.8
Step-by-step explanation:
Given
-10x+4=52
Subtract 4 on both sides
-10x+4-4=52-4
-10x=48
Divide -10 on both sides
-10x/-10=48/-10
x=-4.8
Hope this helps!! :)
Please let me know if you have any questions
We can first find how much the ribbon cost for 1m by setting an equation.
Let $y be the cost for 1m:
0.8y = 5.60
y = 5.60 ÷ 0.8
y = 7
Now that we know 1m of ribbon cost $7, we can proceed to find how much 3.25m ribbon cost by mutiplying the length with the cost:
7 x 3.25
=$22.75
Therefore the answer is $22.75.
Hope it helps!
Answer:
151
Step-by-step explanation:
Let x = the smaller integer and y = the larger integer.
We have two conditions:
(1) x + 1 = y
(2) y = 2x - 149 Substitute (1) into (2)
x + 1 = 2x - 149 Add 150 to each side
x + 150 = 2x Subtract x from each side
x = 150 Substitute into (1)
150 +1 = y
y = 151
The larger integer is 151.
<em>Check:
</em>
(1) 150 + 1 = 151
151 = 151
(2) 151 = 2×150 -149
151 = 300 -149
151 = 151
Answer:
n>1
Step-by-step explanation:
usually, you can solve an inequality as if it were a regular equation. Just be aware of the instances where the inequality flips.
