Step 1: Define
5(x - 8) + 7 = 2
Step 2: Solve for x
Subtract 7 on both sides: 5(x - 8) = -5Divide 5 on both sides: x - 8 = -1Add 8 on both sides: x = 7Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 5(7 - 8) + 7 = 2(Parenthesis) Subtract: 5(-1) + 7 = 2Multiply: -5 + 7 = 2Add: 2 = 2Here we see that 2 does indeed equal 2.
∴ x = 7 is the solution to the equation.

Answers
Answer:
19
Step-by-step explanation:
Given the polynomial :
x2 + bx + 18 ;
The polynomial Given is if degree 2 ;
The equation can be solved using the quadratic function degree 2 to check which of the options given can be factored :
Here,
a = 1 ; b =? c = 18
Checking each option :
If b = 17
x2 + 17x + 18 = 0
x2 + 17x + x + 18 = 0
(x + 17)(x + 1)
If b = - 19
(x-1)(x-18)=0

Mya and ERIC WORK IN A BAKERY . MYA HAS 3 TIMEA AS MUCH FLOUR AS ERIC .MYA HAS 15.81LB OF FLOUR .USE THE EQUATION 3F = 15.81 TO FIND HOW MUCH FLOUR ERIC HAS .
Answers
Answer:
5.27 lb
Step-by-step explanation:
Given that,
Mya has 3 times as much floor as Eric. Mya has 15.81 lb of floor. The relation is given by :
Let Eric has F floor.
3F = 15.81 ...(1)
We need to find how much flour Eric has.
Dividing both sides by 15.81.
F = 15.81/3
F = 5.27 lb
Hence, Eric has 5.27 lb of flour.

The equation of a straight line is y = 20 – X.
If the x value of a point on the line is 14, what is the y value of this point?
Answers
Given:
The equation of a straight line is
[tex]y=20-x[/tex]
The x value of a point on the line is 14.
To find:
The y value of this point.
Solution:
If a point (x,y) lines on line, then the equation of line must be stratified by that point.
We have, the equation of a straight line.
[tex]y=20-x[/tex]
Putting x=14, we get
[tex]y=20-14[/tex]
[tex]y=6[/tex]
Therefore, the y-value is 6 when the x-value is 14.
Which function is linear?
Answers
Answer:
Its D
Step-by-step explanation:
The word linear is used for a straight line. A linear function is a function of a straight line, which means that the degree of a linear function must be 00 or 11. In this case, The degree of f(x)=x5−10f(x)=x5-10 is 11, which makes the function a linear function.
f(x)=x5−10f(x)=x5-10 is a linear function

What property of operations will be used to simplify the product of a binomial and trinomial? *
Answers
Answer:
Distributive property.
Step-by-step explanation:
A distributive property is a rule that states that, multiplying two factors such as a binomial and trinomial would give the same result as multiplying the sum of two addends by the other factor.
Hence, the distributive property is used to simplify the product of a binomial and trinomial.
For example, let's find the product of (2x + 4)(5x² + 3x + 10)
First of all, we would distribute trinomial into each of the term in the binomial.
2x(5x² + 3x + 10) + 4(5x² + 3x + 10)
Distributing the monomial into the trinomial, we have;
2x(5x²) + 2x(3x) + 2(10) + 4(5x²) + 4x(3x) + 4(10)
Expanding the bracket, we have;
10x³ + 6x² + 10 + 20x² + 12x² + 40
Collecting like terms, we have;
10x³ + (6x² + 20x² + 12x²) + 10 + 40
10x³ + 38x² + 50
Therefore, (2x + 4)(5x² + 3x + 10) = 10x³ + 38x² + 50

In the morning, the temperature in Westfield City was -2°F. By afternoon,
a north wind caused the temperature to drop another 8°F. What was the
afternoon temperature in Westfield City? To solve the problem, Martin
subtracted -2-(-8) and came up with an answer of 6°F. Is Martin correct?
Why or why not?
Answers
The afternoon temperature in Westfield City is -10°F.
Martin is not correct.
Calculating TemperatureFrom the question, we are to determine the afternoon temperature in Westfield City
From the given information,
"In the morning, the temperature in Westfield City was -2°F"
and
"By afternoon, a north wind caused the temperature to drop another 8°F"
Thus,
The afternoon temperature = -2°F - 8°F
The afternoon temperature = -10°F
Hence, the afternoon temperature in Westfield City is -10°F.
Martin is not correct.

Y=2x+0
Step-by-step explanation:
First you have to find the slope of the graph or the rise over run, which in this case is 2
Then you have to find the y intercept, which is zeroSo the rule for thos graph is y=2x+0.
To double check our work take a random point on x axis. I chose the point 1,2
fill in the formula and you should get 2(1)+0=2 and therefore this Formula is correct
Step-by-step explanation:
Graph y-2x=0
y−2x=0
Add 2x to both sides of the equation.
y=2x
Use the slope-intercept form to find the slope and y-intercept.
Slope: 2y-intercept: 0
