Answer:
y = 2x + 0 or y = 2x
Step-by-step explanation:
use slope-intercept form [tex]\frac{y2 - y1}{x2 - x1}[/tex]
12 - 10 = 2
6 - 5 = 1
m value = 2/1 = 2
y=2x+b
to find b plug one of the points in for x and y
Example: 10 = 2(5) + b
solve equation
10 = 10 + b
subtract 10 from both sides
0 = b
Equation of line equals y=2x+0 or simply just y=2x

Find the equation of the exponential function represented by the table below:
Answer:
y = 4 [tex](2)^{x}[/tex]
Step-by-step explanation:
For an exponential function in standard form
y = a [tex](b)^{x}[/tex]
To find the values of a and b, use ordered pairs from the table
Using (0, 4 ), then
4 = a[tex]b^{0}[/tex] ( [tex]b^{0}[/tex] = 1 ), so
a = 4
y = 4[tex]b^{x}[/tex]
Using (1, 8 ), then
8 = 4[tex]b^{1}[/tex] = 4b ( divide both sides by 4 )
2 = b
Thus
y = 4 [tex](2)^{x}[/tex] ← exponential function

b-7/4 = 1/2
Answer:
b=1/2+7/4
b= 9/4
Step-by-step explanation:
yup......
Answer: b= 9/4
Step-by-step explanation: Multiply the numbers B-1 * 7/4 = 1/2
B- 7/4 = 1/2
then add 7/4 to both sides of the equation and simplify and your solution is B=9/4
8 – 2x =

The four signs are
< which is a "less than" sign
> which is a "greater than" sign
[tex]\le[/tex] which is a "less than or equal to" sign
[tex]\ge[/tex] which is a "greater than or equal to" sign
Answer:
C) four
Step-by-step explanation:
to mark an inequality you have
less than (<),
greater than (>)
less than or equal (≤)
greater than or equal (≥)
and the not equal symbol (≠) but I assume your teacher didn't count this one for this question so just go with four :D
Evaluate f(x)=4x+5 when x=4.
21
Step-by-step explanation:
=4x+5
=4*4+5
=16+5
=21
The value of function f(x) = 4x + 5 when x = 4 is 21 the answer is 21.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a function:
f(x) = 4x + 5
Plug x = 4
f(4) = 4(4) + 5
f(4) = 16 + 5
f(4) = 21
Thus, the value of function f(x) = 4x + 5 when x = 4 is 21 the answer is 21.

What is the answer to -2.6f + 0.7f - 12 -9
Simplify if needed
DUE TODAY!!!!!!
Answer:
= -1.9f - 21
Step-by-step explanation:
Let's simplify
-2. 6f+ 0.7f- 12 - 9
= - 2.6f+ 0.7 f + - 12 + - 9
Combine like terms
= - 2.6 f+ 0.7 + - 12 + - 9
= (-2.6f + 0.7f ) + ( - 12+-9)
=1.9f+ -21

Larson uses 2 tablespoons (tbsp) of oil for every 5 tablespoons of vinegar in a science experiment. He uses a total of 20 tablespoons of vinegar. The tape diagram below represents this situation.
image 7ab5bfdf0ba844ca8e92c8aff1fdf52a
How many tablespoons of oil should Larson use?
Answer:
8 tablespoons
Step-by-step explanation:
your ratio is 5:2 so for every 5 we will need 2. so 5 times what is 20. well 4 so now we need to multiply 2 by 4 to get 8 and your ratio becomes 20:8.
Sorry, I had done this wrong but I can't delete it. Look at

Answer:
Mira
Step-by-step explanation:
Rhona runs a measly 6 mph, nd Mira runs about 1.3. You gotta divide 8 by 6.
OR,
u can make common denominators. Make Rhona's 1 hour 6 hours, then multiply 6 by 6. Therefore, in 6 hours, Rhona runs 36 miles.

a half of whats johns age was 4 years ago is equal to one third of what will be in 5 years time. how old is john now?
Let x = John's age now
half of what johns age was 4 years ago: (1/2)(x-4)
is equal to one third of what it will be in 5 years time: (1/3)(x+5)
(1/2)(x-4) = (1/3)(x+5)
3(x-4) = 2(x+5)

Eva and Jamir like to bake cookies. Eva baked 24 chocolate chip cookies, and Jamir baked p peanut butter
cookies. Together they baked a total of 56 cookies,
Write an equation to describe this situation.
How many cookies did Jamir bake?
Answer:
Step-by-step explanation:
1) 24+P=56
You then would subtract 24 from the left and move it to the 56 side of the equation.
2)P=56-24
You then take 56-24=32.
3) P=32
Solve for x in the diagram below.
9514 1404 393
Answer:
x = 20
Step-by-step explanation:
The sum of the given angle expressions is 90°, the measure of the right angle:
x + (3x +10) = 90
4x = 80 . . . . . . . . . subtract 10
x = 20 . . . . . . . . . . divide by 4
Answer:
x = 20
Step-by-step explanation:
Key skills needed: Complementary Angles, Equations
1) We are given this diagram and we want to find out x.
The 2 angles (One with the measure "x degrees" and the other with the measure of "3x+10") are complementary. This means that both their measures add up to equal the measure of a right, or 90 degrees.
2) This means we can make the equation --> [tex]x + 3x + 10 = 90[/tex]
To solve:
Combine like terms (3x + x = 4x) --> [tex]4x + 10 = 90[/tex]
To get "x" by itself, subtract 10 from both sides (90 - 10 = 80)
This means it would be --> [tex]4x = 80[/tex]
Divide by 4 from both sides (80 divided by 4 is 20) and get x = 20
Therefore 20 is your answer.

Mark has a piece of wood that is 11 1/4 ft long. He cuts the wood into as many 2 1/2 ft pieces as he can. How long is the leftover piece of wood?
Answer:
1 1/4 ft
Step-by-step explanation:
First lets convert the fractions to decimals so it will be easier to divide. We need to divide to know how many leftover pieces of wood are there. 11.25 (11 1/4) divide by 2.5 (2 1/2) is 4 with the reminder of 1.25. So there are 4 (2 1/2 ft) wood pieces and 1 1/4 ft leftover piece of wood.
