Can anyone help me with this algebra problem ?
Answer:
Its just where the lines meet, (2,1)
Step-by-step explanation:
select the equation represented by the graph
Answer:
b) y = -2/3 + 1
Step-by-step explanation:
The format for the equation is y = mx + b
(m is the slope, and b is the y intercept)
Slope is rise over run (the units the line moves up and the units the line moves to the right)
In this case, the slope is: -2/3 because it goes down 2 and to the right 3.
The y intercept is 1.
This makes our equation:
y = -2/3 + 1
1.
Find the slope of the line.
Ay
a) -574
b) 5/4
c) -4/5
d) 4/5
Answer:
a) -5/4
Step-by-step explanation:
Slope is fundamentally rise/run; The points on the line are relative to each other by decreasing/increasing the y-value of +/-5 and decreasing/increasing the x-value by +/-4
The function is decreasing so the slope has to be negative.
The only possible answer choice is -5/4 or a.

Use the order of operations to evaluate the expression. 8+2(3+4)÷2
Answer:
8+2(3+4)÷2 = 10
Step-by-step explanation:
The order of operation is a set of rules that guides how mathematical operations are done, to make for a universal solution.
Let us apply the rules while solving the problem 8+2(3+4)÷2
The rule is summarized in a set of Acronym known as PEMDAS
P - Parenthesis(Bracket) = (3+4) = 7
The expression becomes: 8+2(7)÷4
E - Exponents: this refers to powers, but is absent in this expression
M - multiplication: 8 + (2 × 7) ÷ 4 = 8 + 14 ÷ 7
D - Division: 8 + (14÷7) = 8 + 2
A - Addition = 8 + 2 = 10
S = subtraction. (absent in this expression)
∴ 8+2(3+4)÷2 = 10
decide whether the equation describes a function
y-2x=-4

For a celebration a town is going to pass out miniature replicas of the town's
bell. The replicas are 9 in. tall. If the scale of the replica is l in. : 0.5 ft, how
tall is the actual bell?
Answer:
The bell is 4.5 feet tall
Step-by-step explanation:
The ratio of the replicas are 1in : 0.5ft, so each inch of the model is 0.5 feet in real life.
The replicas are 9 inches tall, so you would multiply by the scale factor, 0.5 feet. You want the units to end up being feet, so you position the fractions to cancel out inches.
[tex]\frac{9}{1}[/tex] in x [tex]\frac{0.5}{1}[/tex] [tex]\frac{ft}{in}[/tex]
the inches cancel out and you are left with:
9 x 0.5 ft
Simplify.
4.5 ft

18. The percentage of the time, Barry reached the base is 53%.
19. The percentage of the class that passed the test is 92%.
Step-by-step explanation:
a. 5% of $788,116 = $39,405.80
b. 75% of $32 = $24
c. John's earnings = $6.25 * 14 = $87.50
Taxes = 18%; therefore, take home = 82% (100 - 18)
He will keep 82% of $87.50 = $71.75
d. Population in 1980 = 95% of 4,800 = 4,560
e. 45% of 452 = 203
f. Mrs Eversole will pay $250 * 0.07 = $17.50
g. 36% of 500 = 180
h. 80% of $350 = $280
i. Actual height = 37.8/135 * 100 = 28 ft
j. If 41% = 294, then 100% = 294/41 * 100 = 717
k. Manuel's total collection = 42/12.5% * 100% = 336
l. If 32% = 1.7 ounces, then the chalk will be 1.7/32% * 100 = 5.31 ounces.
m. If 56% = 14, then Wanda shot 14/56% * 100% = 25
n. Newmark to Briton will be 160/85% * 100 = 188 miles
o. If 80% = 24, then the number of questions = 24/80% * 100 = 30
p. Anfernee missed 36 shots = 19% (36/191 * 100)
q. 36/225 * 100 = 16%
r. The percentage of the time, Barry reached the base is 342/644 * 100 = 53%
s. 23/25 * 100 = 92%

Find the value of x.
The value of x is 17.
Given,
The figure of a straight line angle.
The angle is split into (12x - 26)°and 50°.
We need to find the value of x.
What is a straight line angle?The angle of a straight line is 180 degrees.
The sum of the angles of a straight line will always be 180 degrees.
Find the value of x.
We have,
(12x - 26)° and 50°
We know that,
The sum of the angles of a straight line will always be 180 degrees.
We have,
12x - 26 + 50 = 180
12x - 24 = 180
12x = 180 + 24
12x = 204
x = 204 / 12
x = 17
Thus the value of x is 17.

Step-by-step explanation:
Solve for n.
21m + 14n=-7
n =
Answer:
n = [tex]\frac{-1}{2}[/tex] - [tex]\frac{3}{2}[/tex]m or n = -0.5 - 1.5m
Step-by-step explanation:
21m + 14n = -7 (subtract 21m from each side)
14n = -7 - 21m (divide everything by 14)
n = [tex]\frac{-7}{14}[/tex] - [tex]\frac{21}{14}[/tex]m
n = [tex]\frac{-1}{2}[/tex] - [tex]\frac{3}{2}[/tex]m or n = -0.5 - 1.5m
3.2y-1.4y+y-0.6y=0.55
Answer:
it is y=0.25
Step-by-step explanation:
because Step 1: Simplify both sides of the equation.
3.2y−1.4y+y−0.6y=0.55
3.2y+−1.4y+y+−0.6y=0.55
(3.2y+−1.4y+y+−0.6y)=0.55(Combine Like Terms)

Step-by-step explanation:
what is the x cordinate of the solution
Answer:
x = - 4
Step-by-step explanation:
Given the 2 equations
y = - 2x - 5 → (1)
y = x + 7 → (2)
Substitute y = x + 7 into (1)
x + 7 = - 2x - 5 ( add 2x to both sides )
3x + 7 = - 5 ( subtract 7 from both sides )
3x = - 12 ( divide both sides by 3 )
x = - 4
