Answer:
y = 2 - 5/4x
or
y = 2 - 1.25x
Step-by-step explanation:
Slope-intercept form is y=mx+b, where m=slope and b=y-intercept. Let's make this equation look more like that by isolating y on one side.
5x + 4y = 8
Subtract 5x from both sides.
4y = 8 - 5x
Divide both sides by 4.
y = 8/4 - 5/4x
y = 2 - 5/4x
Answer:
B and D
Step-by-step explanation:
3*(5²)-42=33
75-42=33
3*((-5)²)-42=33
75-42=33
Answer:
7.5
7.49 rounded to the nearest tenth is 7.5 because there is a 9 in the hundredths place.
Answer: 12 pounds.
Step-by-step explanation:
To solve this question, we'll use the direct proportion which is.
y = kx
Where,
y = weight on moon = 48 pounds
x = weight on Earth = 300 pounds
k = Unknown
y = kx
48 = 300k
k = 48/300
k = 0.16
The weight that a 75 pound object on Earth would weigh on the moon will be:
y = kx
where,
y = weight on moon = Unknown
k = 0.16
x = weight on Earth = 75 pounds
y = kx
y= 0.16 × 75
y = 12 pounds
The weight on the moon will be 12 pounds.
Hello,
cos 160°=-q
cos 20°=-cos 160°=q
sin 20°=√(1-q²)=sin 160°
tan -20°=tan 160=√(1-q²)/-q
cos 70°=sin 20°=√(1-q²)
