Answer:
y=mx+b
-4x+4=y
Step-by-step explanation:
slope=-4
-4=-4(2)+b
-4=-8+b
add -8 to both sides
4=b
-4x+4=y
The line y = mx + c passes through the points (-2, 1) and (4,4).
Write down a pair of simultaneous equations involving m and c.
Solve the simultaneous equations.
Answer:
Step-by-step explanation:
Insert x for -2 & 4 and y for 1 & 4
1=-2m+c, 4=4m+c
solve the equation, m=1/2, c=2
Answer:
y = 1/2m + 2
Step-by-step explanation:
1 = -2m + c (1)
4 = 4m + c (2)
2 = -4m + 2c (1*)
(1*) + (2) = 6 = 3c
c = 2
y = mx + 2
4 = 4m + 2
2 = 4m
m = 1/2
so y = 1/2m + 2

Jalen bought 9/16 pound of blue cheese at the deli. He also bought 1 3/16 pounds of Swiss cheese. He estimates that the he bought about 1 3/4 pounds of cheese altogether. Which best describes Jalen's estimate?
A. It is not reasonable because 9/16 is about 3/4 and 1 3/16 is about 1 1/2, and 3/4 + 1 1/2 = 2 1/4.
B. It is reasonable because 9/16 is about 1/2 and 1 3/16 is about 1 1/4, and 1/2 + 1 1/4=1 3/4.
C. It is not reasonable because 9/16 is about 1 and 1 3/16 is about 1, and 1 + 1 = 2.
D. It is reasonable because 9/12 is about 1 and 1 3/16 is about 1, and 1 + 1 = 2/2, which is about 1 3/4.

What's the circumference and area?
Answer:
43.98 (44) Circumference
Area: 153.94 (154)
Step-by-step explanation:
Answer:
Circumference: 14π square inches or approximately 43.96 square inches
Area: 49π square inches or 153.86 square inches
Step-by-step explanation:
Circumference = 2πr, where r = radius
2π(7) = 14π or 14(3.14) = 43.96
Area = πr^2, where r = radius
π7^2 = 49π or 49(3.14) = 153.86

Answer:
y = 1500(1.079)^t
Step-by-step explanation:
Here, we want to write an exponential function
Mathematically, we have this generally as;
FV = IV( 1 + r)^t
where FV is future value which is y in this case
IV is the initial value which is 1,500 kn^2 in this case
r is the rate of change which is 7.9%
7.9/100 = 0.079
t is the time difference
so we have the equation as;
y = 1500(1 + 0.079)^t
y = 1500(1.079)^t

Answer:
50
Step-by-step explanation:
Since it's a right angle, it's automadically 90 degrees. Add 29 + 13 which gives you 42. 90 - 42 gives you 48. Rounded to the nearest 10th is 50. Here's what I explained in numerical form:
29 + 13 = 42
90 - 42 = 48
Five or more raise the score. For or less turn to zero:
48
8 is larger than 5 so you add "plus 1" to the next number:

Aaron saw it was 86° Fahrenheit, F, in Australia in January. Aaron used the formula C=5/9(F−32) to find the temperature in degrees Celsius, C. What temperature, in degrees Celsius, did Aaron find?
Answer:
[tex]30^{\circ}\text{C}[/tex]
Step-by-step explanation:
The temperature that Aaron saw was [tex]86^{\circ}\text{F}[/tex]
The formula to convert Fahrenheit to Celsius is
[tex]C=\dfrac{5]{9}(F-32)[/tex]
[tex]\Rightarrow C=\dfrac{5}{9}\times (86-32)[/tex]
[tex]\Rightarrow C=30^{\circ}\text{C}[/tex]
The given temperature in Celsius that Aaron found would be [tex]30^{\circ}\text{C}[/tex].

calculate the difference
divide both sides of the equation by 4

Answer:
w = 3
Step-by-step explanation:
Isolate the w term by subtracting the constant on that side.
75 -75 -4w = 63 -75
-4w = -12
Get w by itself by dividing by its coefficient.
-4w/-4 = -12/-4
w = 3

A designer decides to create a larger scale model of a smart phone so that his team can work more easily on the design. The length of the screen of his model is 60 centimeters, which is 2.5 times longer than it is wide. The designer asked his team to build the screen of the actual phone with a width of 6 centimeters. What is the scale factor of the model phone to the actual phone?
Answer:
The length of the model is 250% of the width and is 60 centimeters, and the width of the actual phone is 6 so it has a scale factor of 4:1.

Answer:
Same arc intercepted, the angles are equal
t = 10°u = 60°v = 40°Cyclic quadrilateral has supplementary opposite angles
s + v + 60° + 10° = 180°s + 40° = 110°s = 70°And s and r intercept same arc, therefore:

feet (60 inches) long. Approximately how
many inches did the trainer raise the
end of the treadmill from the floor?
Answer:
Step-by-step explanation:
sin Ф equal the opposite leg of the triangle dividend by the hypotenuse
sin Ф = opp / hyp
the problem gave you the Ф (the angle 7°)
and the length of the hypotenuse (the walking surface 60 inches)
You want to use the inches since the question wants to know how many inches off the floor is the end of the walking surface
sin 7 = opp / 60 solve for opp
60 × sin(7) = opp use your calculator, I don't have one handy
