Answer
D
Step-by-step explanation:
y=2x+15
7=2(-4)+15
7=15-8
7=7
7x+2y=-14
7(-4)+2(7)=-14
-28+14=-14
-14=-14
For shipping packages, UPS charges $7.00 for the first pound, and $0.20 for each additional pound. FedEx charges $5.00 for the first pound and $0.30 for each additional pound. How many pounds will it take for UPS and FedEx to cost the same? Using p for the number of pounds, write and solve and equation to represent this situation.
Answer:
x=20
Step-by-step explanation:
7+0.20x=5+0.30x
then take the 7 and subtracet the 2 from it, then take the 0.30 and subtract the 0.20 from it then you should get 2=0.10x
then to get rid of the 0.10 you take it and divide it from the 2 which gives you 20 then you have 20=x and thats your answer
What is the value of x in the equation: 3x – 5x + 10 = 36

(f * g)(x)=(5x^3)*(x+1)=5x^4 +5x^3
what is the slope intercept formula
Answer:
y=mx+b
Step-by-step explanation:
Answer:
y=mx+b
Explanation:
The slope-intercept formula is y=mx+b. The b represents the y-intercept, which is the point where a line on a graph meets the y-axis. The coordinates for this would be (0,b). The m represents the slope, which is the rate of change. The x represents any x variable that you plug in. The y represents the y variable.

So first of all you count all the blocks, so it will be 16 blocks (4x4) sideways and horizontal.
A = 16/4 marked blocks = 25%
B = 16/8 marked blocks = 50%
C = 16/6 marked blocks = ?
D = 16/10 marked blocks = 62,5%
So answer would be A

Find the exact value of Cosine (alpha + beta) given sin Alpha = two-fifths for Alpha in Quadrant II and Cosine Beta = one-third for Beta in Quadrant IV.
The exact value of cos (α + β) is (4√2-21) / 15.
What is angle?An angle is the formed when two straight lines meet at one point, it is denoted by θ.
Given that,
Sin α = 2/5, and α is in second quadrant,
cos β = 1/3 , and β is in fourth quadrant
Since, α is in second quadrant, the value of cos α will be negative.
The value of cos α, by right angle triangle property,
cos α = -√21 / 5
Since, β is in the fourth quadrant, the value of sin β will be negative.
The value of sin β = - 2√2 / 3
Cos (α + β) = cos α.cos β - sin α. sin β
Substitute the values here,
Cos (α + β) = (-√21 / 5) . 1/3 - 2/5. ( - 2√2 / 3)
= -21/15 + 4√2/15
= (4√2-21) / 15
The value of cos (α + β) is (4√2-21) / 15.

Step-by-step explanation
Add 14 to both side(because it is opposite)
-6=8x-14
+14 +14
8=8x
Divide both sides by 8
8/8=8x/8
1=1x(or just 1=x)
The answer will be X=1.
