So y=mx+b
the 'm' part means the slope which is found by 'rise/run'
a. y=2x+3 or y=2x+3
b. y=-1x+6
c. i'm not sure what this part means
d. this means 'what values will work for x and y in both equations at once so
y=-x+6 and y=2x+3
y=-x+6
add x to both sides
x+y=6
subtitute 'y=2x+3' for y in x+y=6
x+(2x+3)=6
collect like terms
3x+3=6
subtract 3 from both sides
3x=3
divide both sides by 3
x=1
sibtitue into x+y=6
1+y=6
subtract 1 from both sides
y=5

(1,5) is the solution (x,y)


Question 2
so amount of peanuts (x) =60%
ammount of almonds (y)=40%
y=2(1/3x) or y=2/3x
so there is a mixture that is8/10 almonds
for
a. i'm not sure about this one
b. so 60% of 5 pounds=3 pounds
40% of 5 pounds=2pounds
we need to find out how many pounds, times 8/10, = 2pounds

 she will need 2.5 pounds of the pure peanuts and 2.5 pounds of the almond-peanut mixture

What is the circumference of <br> 26 cm
IgorC [24]

Answer:530.9

Solution Steps:

Area of a circle in terms of radius:

Area = π . r2 = 3.14 × 132 = 530.9 square cm.

In terms of diameter:

Area = π . (d/2)2 = 3.14 × (26/2)2 = 3.14 × (13)2 = 530.9 square cm.

In terms of circumference:

Area = C2/(4π) = 81.682/4π = 6671.62/(4 × 3.14) = 6671.62/(12.56) = 530.9 square cm.

Note: for simplicity, some results may be rounded to nearest hundredth and π was rounded to 3.14. See formula details below in this page.

A circle of radius = 13 or diameter = 26 or circunference = 81.68 cm has an area of 530.9 square centimeters which is equal to:

5.309E-8 square kilometers (km²)

0.05309 square meters (m²)

1.312E-5 acres (ac)

5.309E-6 hectares (ha)

2.05E-8 square miles (mi²)

0.0635 square yards (yd²)

0.5715 square feet (ft²)

82.29 square inches (in²)

What is the unit rate for 15 degrees in 2 hours
guajiro [1.7K]
Ok in order to get the unit rate you need to take w.e. unit you have and make it 1, so if you have 15 degrees in 2 hours and it wants you to get the unit rate you need to find the degree it will be in 1 hour so you just take 15 and divide it by 2 and your unit rate is 7.5 degrees in one hour

Find the line of inclination of the line if its slope is -√3​
gregori [183]

Answer:

120° or 300°

Step-by-step explanation:

Given,

Slope (m) = -√3

Inclination (α) = ?

Now,

We know,

m = tanα

or, -√3 = tanα

or, tan(120° or 300°)  = tanα

∴ α = 120° or 300°

∴ Inclination is 120° or 300°
