Answer:
y=-3.5x-9.5
Step-by-step explanation:
Answer:
Step-by-step explanation:
so we use the equation y2-y1=m(x2-x1)
let's say (-3,1) is point 1 and (-5,8) is point 2
we plug in what we know
8-1=m(-5-(-3))
subtracting a negative is the same as adding so -5 - (-3) = -2
7=-2m
divide both sides by -2
-7/2=m
-3.5=m
so slope intercept form is y=mx+b
we know the slope (m) but we still need the "b" which is the y-intercept.
so you pick whichever point you want (I'm going to chose point 1 but it doesn't matter) and plug it in
1=-3.5(-3)+b
1=10.5+b
-9.5=b
so the equation would be y=-3.5x-9.5
a system of inequality, where x is the rate of a spaceship in a video game and y is where the ship travels on the screen in 3.5 seconds, is represented by the graph. which symbol could be written in both circles in order to represent this system algebraically?
Answer: B. >=
Step-by-step explanation: Sorry if I'm late, but here's proof. If you see that both the lines intersect and split ways at -6 x-int on the graphing calculator, its the same graph. So the answer would be >=.
:)
The system of inequality is solved and 3 ≤ x ≤ 5
What is an Inequality Equation?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
y ≤ (7/4)x + (17/2) (left circle)
y ≥ (7/4)x + (17/2) (right circle)
So, we can write the system of inequalities algebraically as:
3 ≤ x ≤ 5
(7/4)x + (17/2) ≤ y ≤ (7/4)x + (17/2)
The correct symbol to write in both circles in order to represent this system algebraically is "≤" (less than or equal to)

#SPJ7
write an equation for the nth term of the arithmetic sequence -7, -2, 3, 8...
Answer:
33
Step-by-step explanation:
An arithmetic sequence has a definite pattern. If we look at the number -7 and -2, what do we have to do to get from -7 to -2? We just have to add 5. To check this, we can add 5 to -2 and it will be 3.
Now, we know what the pattern is. Now, we have to find the ninth term using this pattern.
8 is the fourth term. So, 5 + 8 is 13. 13 is the fifth term. 13 + 5, is 18. 18 is the sixth term. 18 plus 5 is 23. 23 is the seventh term. 23 plus 5 is 28. 28 is the eighth term. Finally, 28 plus 5 is 33. 33 is the ninth term.
120 men and 80 women were asked if they drive to work.
Altogether 1/4 of the people said yes.
1/3 of the men said yes.
What fraction of the women said yes?
Answer:
1/8 of the women said yes
Step-by-step explanation:
Answer:
1/8
Step-by-step explanation:
In total there is 200 people (120+80)
1/4 of that is 50 people, keep this for later.
1/3 of 120 men is 40.
Subtract the men that said yes from the people that said yes. We get 10 women said yes.
If we put 10 over 80 (10/80) we can simplify that by reducing by 10, so 1/8 of the women said yes
alan is spreading fertilizer on a field to get it ready for planting. The directions say to use 4/5 of a quart of fertilizer for each acre of land. Alan has two fields, one that is 22 1/2 and one that is 38 1/4. How much total fertilizer will Alan need for his two fields?
Answer:
48.6 quart of fertilizer
Step-by-step explanation:
The directions say to use 4/5 of a quart of fertilizer for each acre of land.
Alan has two fields,
Field 1
22 1/2 acre of land
1 acre of land = 4/5 quart
22 1/2 acre of land = x
Cross Multiply
x = 22 1/2 × 4/5
x = 45/2 × 4/5
x = 18 quart of fertilizer
Field 2
38 1/4 acres of land
1 acre of land = 4/5 quart
38 1/4 acre of land = x
Cross Multiply
x = 38 1/4 × 4/5
x = 153/4 × 4/5
x = 30.6 quart of fertilizer
The total fertilizer that Alan will need for his two fields is calculated as:
18 quart of fertilizer + 30.6 quart of fertilizer
= 48.6 quart of fertilizer

Complete the table of values for y= 2x-4
Answer:
-8,-6
Step-by-step explanation:
The completed table for y = 2x - 4 is ( - 2, 0), (- 1, - 6), and (0, -4)
What is a function?A function can be defined as the outputs for a given set of inputs.
The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.
Given, A function y = 2x - 4.
Now at x = - 2 we'll simply put the numerical value of x in y.
y = 2(2) - 4.
y = 4 - 4.
y = 0.
( - 2, 0).
At x = - 1.
y = 2(-1) - 4.
y = - 2 - 4.
y = - 6.
(- 1, - 6).
At x = 0.
y = 2(0) - 4.
y = 0 -4.
y = -4.
(0, -4)

A man spent 58% of his income and the amount of money left was $210 .Find his income.
Answer:
Step-by-step explanation:
First, subtract 58% from 100% to get 42%. That means $210 is 42% of this man's income.
Then, convert 42% into a fraction. This would be 21/50. Find the reciprocal of that, which is 50/21.
Now, multiply 50/21 by 210 to get the answer.
(50 * 210)/21
Multiply 50 by 210 to get 10500.
10500/21
(105/21) * 100 is the same as 10500/21.
Divide 105 by 21 to get 5.
5 * 100
Multiply 5 by 100 to get 500.
The man has a $500 income.

Not entirely sure about this one; you might have to round the answer.
Is this correct or no
Answer:
Incorrect
Step-by-step explanation:
The correct answer is A.
The slope-intercept form is y-y₁=m(x-x₁)
The problem with B is that if you take out the coordinates for x₁ and y₁, you get the coordinates (1,4). This coordinate does not land on the line.
The coordinates for A is (-1,4). This point does land on the line.

Amelie's bird cage is shaped like a rectangular prism. The cage has a height of 26 inches and a volume of 7,280 cubic inches. Amelie puts a piece of newspaper on the bottom of the cage. The newspaper fits the bottom of the cage perfectly.
What is the area of the newspaper on the bottom of the cage?
Answer:
The area of the news paper which fits in the bottom of the Amile's cage is 280 square inches because The area is said to be the product of the two sides ( length an breadth ) of the rectangle.
The volume is said to be the product of the length, breadth and height of the cage.
Here the height and volume are given in the square inches.
volume = L* B *H = 7280 Square inches whereas height is 26 inches.
AREA = L* B = by bringing the height in divide with volume we can obtain the L* B value which is said to be the value of the height .
