Answer:
-0.375
Step-by-step explanation:
Way one(the harder one):
Let the line which passes through (1,4) and (9,1) be f(x)=kx+b
Sub (1,4) and (9,1) in and we get [tex]\left \{ {{4=1k+b} \atop {1=9k+b}} \right.[/tex]
=> (9k+b)-(k+b)=1-4
8k=-3
k=-3/8 or -0.375
Therefore the slope of the line is -3/8 or -0.375
Way two(the easier one):
k= [tex]\frac{change in y}{change in x}[/tex] = [tex]\frac{1-4}{9-1}[/tex] = -[tex]\frac{3}{8}[/tex]

[tex] \frac{x}{9} \geqslant 3 \\ [/tex]
Multiply sides by 9
[tex]9 \times \frac{x}{9} \geqslant 9 \times 3 \\ [/tex]

Rewrite 56 + 32 as the product of the GCF and a sum.
Answer:
8(7 + 4)
Step-by-step explanation:
The GCF of 56 and 32 is 8 , thus
56 + 32 = 8(7 + 4 )
56 + 32 = 88
8(7 + 4) = 8 × 11 = 88
Solve the inequality.

Use the diagram and the given angle measure to find the other three measures.
m∠1=143∘
m∠2=
m∠3=
m∠4=
Answer:
angle 2 = 37⁰
angle 3 = 153⁰
angle 4 = 37⁰
Step-by-step explanation:
I guess this refers to two intersecting lines which form 4 angles.
Angles 1 and 2 are supplementary angles whose sum is 180⁰.
Angle 1 + angle 2 = 180⁰
143⁰ + angle 2 = 180⁰
angle 2 = 180⁰ - 143⁰
angle 2 = 37⁰
Angles 1 and 3 are vertical angles so do with angles 2 and 4. Therefore it is easy to find their measures because vertical angles are congruent in measures.
Hope this helps...
Answer:
m∠1 = 143°
m∠2 = 37°
m∠3 = 143°
m∠4 = 37°
Hanna says you cannot represent the fraction 1/4 on the number line.
Answer:
The answer is D; Hanna is not correct,. The fraction 1/4 is equal to 2/8, so you can graph it on the second tick mark to the right of zero.
Step-by-step explanation:
Because the number line is broken up into 8 parts, the points on the graph are, 1/8, 2/8, 3/8, 4/8, 5/8, 6/8, 7/8, 8/8 (also known as one)
1/4 = 2/8. We know this because if we multiply 1/4 by 2, we get 2/8.
So, because 2/8 is the same as 1/4, we know that Hanna is not correct, and that you can graph 1/4 on this number line, because it is the same as 2/8.
I hope that this helps :)

Step-by-step explanation:
find the slope and the y intercept of the points (0,1) and (2,-3)
Answer:
The slope is -2 and y intercept is 1
Step-by-step explanation:
The slope is found by finding the run, or change in x coordinates from coordinate 1 to 2, which is 2 in this problem, and the rise, or change in y coordinates from coordinate 1 to 2, which is -4 in this problem. To find the y-intercept, you need to find the point on the line that has a x coordinate of 0, which is (0,1) on this line, which means the y-intercept is the y value of the coordinate, or 1.

In triangle QRS, angle Q measures 33.7°, angle R measures 52.3°, and angle S measures 94º. Based on the information that is provided, which could be a correct set of sides for this set of angles?
O side QR = 7 cm. side RS = 10 cm , side QS = 12.6 cm
O side QR = 10 cm, side RS = 7 cm, side QS = 12.6 cm side
O QR = 12.6 cm, side RS = 10 cm, side QS = 7 cm
O side QR = 12.6 cm, side RS = 7 cm, side QS = 10 cm
You know, it's easier to draw it out to figure out the answer!
It's side QR = 12.6 cm, side RS = 7 cm, side QS = 10 cm. So, it's D. (last option)

The function f (x) = 6x + 13 defines a
sequence for x > 1. What are the first three
terms of the sequence?
Answer:
15, 21, 27
Step-by-step explanation:
Given the function :
f(x) = 6x + 13 ; which defines a sequence for x > 1
The first three terms of the sequence ;
x > 1 ;
Hence x = 2, 3, 4
The sequence :
f(2) = 6(2) + 3 = 12 + 3 = 15
f(3) = 6(3) + 3 = 18 + 3 = 21
f(4) = 6(4) + 3 = 24 + 3 = 27

Amelia and her brother had a snow day, so they played in the snow for 3 hours. During that time, it snowed another 4.8 inches. If the snow fell at a steady pace, how much snow fell each hour?
Answer:
1.6
Step-by-step explanation:
The amount of snow fell each hour is 1.6 inches per hour.
What is Unit Rate?Unit rate is the amount of one quantity for a unit amount of the other quantity.
In other words it compares 1 unit of some quantity with different amount of another quantity
Given that,
Time Amelia and her brother played in the snow = 3 hours
Amount of snow fell at that time = 4.8 inches
That is 4.8 inches of snow per 3 hours
We have to calculate the unit rate of the amount of snow falling in an hour.
Amount of snow in 1 hour = 4.8 / 3 = 1.6 inches per hour
Hence the 1.6 inches of snow is falling per hour.
