Answer:
y=-2x+b
Step-by-step explanation:
The slope ("m") is 2... rise over run, the line goes up two, and then to the side once, which is 2/1 (aka 2). Since the line is going downhill, it is negative.
Which of the following points does not lie on the line y = -2x +5?
A. (4-3)
B. (-2,9)
с. (3,1)
D. (-1,7)
E. (2, 1)
Answer:
C (3, 1 )
Step-by-step explanation:
To determine if a point lies on the line, substitute the x- coordinate of the point into the equation and if the value obtained equals the y- coordinate of the point then it lies on the line, otherwise not on line.
A (4 , - 3)
y = - 2(4) + 5 = - 8 + 5 = - 3 ← lies on line
B (- 2, 9 )
y = - 2(- 2) + 5 = 4 + 5 = 9 ← lies on line
C (3, 1 )
y = - 2(3) + 5 = - 6 + 5 = - 1 ≠ 1 ← not on line
D (- 1, 7 )
y = - 2(- 1) + 5 = 2 + 5 = 7 ← lies on line
E (2, 1 ) = - 2(2) + 5 = - 4 + 5 = 1 ← lies on line
Thus (3, 1 ) does not lie on the line → C

Solve -19 - m = 8 + 8m
Answer:
m = -3
Step-by-step explanation:
−m − 19 = 8m + 8 (Simplify equation)
−9m − 19 = 8 (Subtract 8m from both sides)
−9m = 27 (Add 19 to both sides)
m = -3 (Divide both sides by -9)

Answer:
your question is poorly written below is the properly written question
Find a coterminal Angle with measure θ ( -22° ) such that 0° ≤ θ < 360°
answer: 338°
Step-by-step explanation:
To find a coterminal angle of a given angle that falls between 0° and 360° we have to express the angle in terms of 360°
Hence express -22° in terms of 360°
-22° = -360° + 338°
hence the coterminal angle = 338°

Josie is making pizza dough. Complete the double number line by filling in the missing values
Answer:

[tex]c:0\ \ \ \frac{3}{4}\ \ \ \frac{3}{2}\ \ \ \frac{9}{4}\ \ \ 3\ \ \ 3\frac{3}{4}\\n:0\ \ \ \ 1\ \ \ 2\ \ \ 3\ \ \ \ 4\ \ \ \ 5[/tex]
Step-by-step explanation:

See attachment for complete question
Required
Complete the double number line
The given double number lines represent a linear function between cups of flour (c) and number of batched (n)
Pick any two pairs:
[tex](c_1,n_1) = (\frac{3}{4},1)[/tex]
[tex](c_2,n_2) = (3\frac{3}{4},5)[/tex]
First, calculate the rate of change (i.e. slope, m):
[tex]m = \frac{n_2 - n_1}{c_2 - c_1}[/tex]
[tex]m = \frac{5-1}{3\frac{3}{4} - \frac{3}{4}}[/tex]
[tex]m = \frac{4}{3}[/tex]
So: the equation is:
[tex]n = m(c - c_1) + n_1[/tex]
This gives:
[tex]n = \frac{4}{3}(c - \frac{3}{4}) + 1[/tex]
[tex]n = \frac{4}{3}c - 1 + 1[/tex]
[tex]n = \frac{4}{3}c[/tex]
So, the above represents the relationship between n and c.
To complete the table
When [tex]n = 2[/tex]
Substitute [tex]n = 2[/tex] in: [tex]n = \frac{4}{3}c[/tex]
[tex]2 = \frac{4}{3}c[/tex]
Make c the subject
[tex]c = \frac{3*2}{4}[/tex]
[tex]c = \frac{3}{2}[/tex]
When [tex]n = 3[/tex]
Substitute [tex]n = 3[/tex] in: [tex]n = \frac{4}{3}c[/tex]
[tex]3 = \frac{4}{3} * c[/tex]
Make c the subject
[tex]c = \frac{3*3}{4}[/tex]
[tex]c = \frac{9}{4}[/tex]
When [tex]c=3[/tex]
Substitute [tex]c=3[/tex] in: [tex]n = \frac{4}{3}c[/tex]
[tex]n = \frac{4}{3} * 3[/tex]
[tex]n = 4[/tex]
So, the complete table is:
[tex]c:0\ \ \ \frac{3}{4}\ \ \ \frac{3}{2}\ \ \ \frac{9}{4}\ \ \ 3\ \ \ 3\frac{3}{4}\\n:0\ \ \ \ 1\ \ \ 2\ \ \ 3\ \ \ \ 4\ \ \ \ 5[/tex]

The difference of a number and 4 is no more than 8
Can someone help!?
Considering the definition of an inequality, the number must be less than 12.
Definition of inequalityAn inequality is the existing inequality between two algebraic expressions, connected through the signs:
greater than >.less than <.less than or equal to ≤.greater than or equal to ≥.An inequality contains one or more unknown values called unknowns, in addition to certain known data.
Solving an inequality consists of finding all the values of the unknown for which the inequality relation holds.
Inequality in this caseIn this case, you know that the difference of a number and 4 is no more than 8.
Being "x" the number you want to know, and considering that the difference is the difference between two numbers or expressions, the inequality that expresses the previous relationship is
x - 4 < 8
Solving:
x < 8 +4
x < 12
Finally, the number must be less than 12.

Dan invests £2200 into his
bank account.
He receives 5% per year simple intrest.
How much will dan have after
2 years?
give your answer to the nearest penny
ühere appropriate
Answer:
the simple interest here would be $220. the total amount he will receive is $2,420.
Step-by-step explanation:
to find how much interest Dan has, you use the formula,
simple interest = principal * interest rate * time
now we substitute the numbers in.
simple interest = $2,200 * 5% * 2
since the rate is a percentage, we have to convert it into a decimal.
simple interest = $2,200 * 0.05 * 2
let's do this step by step.
simple interest = $2,200 * 0.05 * 2
simple interest = $110 * 2
simple interest = $220
to find out how much Dan will earn after two years, we have to find the total amount by adding the interest and the amount of principal.
since we now know the interest, let's add it by the principal.
$220 + $2,200 = $2,420
Therefore, Dan will have $2,420 after two years.
