Step-by-step explanation:
Answer:
Step-by-step explanation:
4x - 17 + 3x + 8 + x + 13 = 180
8x + 4 = 180
8x = 176
x = 22
<A = 4x - 17
<A = 4*22 - 17
<A = 88 - 17
<A = 71
============
<B = 3x + 8
<B = 3*22 + 8
<B = 66 + 8
<B = 74
============
<C = x + 13
<C = 22 + 13
<C = 35
A B and C add to 180 as they should.

If f(x)=3x-4, f(-2) =10 true or false
Answer:
False
Step-by-step explanation:
plug -2 in for x. 3(-3)-4=-10 and -10 isn't 10 so false.
(can I get brainliest please)
Answer:
False
Step-by-step explanation:
f(x) = 3x-4
f(-2) = ?
Substitute -2 for x in the given equation
f(-2) = 3(-2)-4
f(-2) = -6-4
f(-2) = -10
-10= 10
FALSE

which point lies on the point of the equation 9y-4x=18
Answer:
3-5 One line passes through the points (0, -4) and (-1 ... Write the equations in slope intercept form and then ... -2x = 9y-18? Dlugo a. ... Cy= - 4x + 13 Dy= 4r + 23.
Step-by-step explanation:
NOOOOOOOOOOOOOOOOOOOOOO NEED
Answer:
(0, 2)
(9, 6)
Step-by-step explanation:
slope intercept form y = mx + b:
9y - 4x = 18 ===> y = 4/9x + 2
Pick any point for x to get y:
If x = 0, then y = 2
If x = 9, then y = 6
above are just two of many but you should get the idea

Hector works 10 hours per week at a part-time job. His original pay rate was $8.50 per hour, but he recently received a raise of x dollars per hour. His new total weekly pay, y, is represented by the equation y = 10(8.5 + x). If Hector earned $100 last week, what was the amount of Hector's raise per hour? A . $12.00 B .$15.00 C. $1.50 D. $3.00
Answer:
$1.50
Step-by-step explanation:
Given the total weekly pay of Hector modeled by the equation;
y = 10(8.5 + x)
We are to find the amount of Hector's raise per hour x given the total oay y = $100
Substitute y = 100 into the equation and find x as shown;
y = 10(8.5 + x)
100 = 10(8.5+x)
100/10 = 8.5 + x
10 = 8.5 + x
x = 10 - 8.5
x = 1.5
Hence the amount of Hector's raise per hour is $1.50

At a store each notebook has a cost of
inequality?
dollars. Which situation can be represented by this
5x < 3x + 2
A The cost of 5 notebooks is greater than the cost of 3 notebooks plus a $2 pen.
B The cost of 5 notebooks is less than the cost of 3 notebooks with a $2-off coupon,
C The cost of 5 notebooks is less than the cost of 3 notebooks plus a $2 pen.
D The cost of 5 notebooks is $2 greater than the price of 3 notebooks.
Answer:
The answer is C.
Step-by-step explanation:
The < sign means that it will be less than so you can remove A and D. But it's not B either because of the $2 off coupon. Off means you would be subtracting meaning it'll look like this 5x < 3x - $2. So the correct answer is C.
Hope this helps!
The inequality is transformed into a sentence will be the cost of 5 notebooks is less than the cost of 3 notebooks plus a $2 pen. Then the correct option is C.
What is inequality?Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.
The act of converting mathematical equations into a specified statement is known as equation-to-sentence transformation.
The inequality is given below.
5x < 3x + 2

Here are 5 lines on a coordinate grid:
Write equations for lines a,b,c,d and e
a:
b:
c:
d:
e:
Answer/Step-by-step explanation:
✔️Equation for line a:
Line a is a vertical line, hence, the slope is undefined. Equation of a vertical line is given as x = k. Where k is the x-intercept and would remain the same irrespective of the corresponding y-coordinates of all the other points on the vertical line.
In line a, the x-intercept is -4. Therefore, the equation for line a would be:
✅ x = -4
✔️Equation for line b:
Line b is also a vertical line, and would be represented as x = k.
The value of k is the point olwhere the line intercepts the x-axis.
Thus, k = 4.
Equation for line b would be:
✅ x = 4
✔️Equation for line c:
Line c is an horizontal line. Slope (m) of a horizontal line is always 0.
It can be represented in slope-intercept form, y = mx + b, where,
m = slope = 0
b = y-intercept = 4 (this is where the y-axis is intercepted by the line)
Thus, substitute m = 0, b = 4 in y = mx + b.
The equation for line c would be:
y = (0)(x) + 4
✅y = 4
✔️Equation for line d:
Slope (m) = 0
y-intercept (b) = -2
Substitute m = 0, and b = -2 in y = mx + b
Equation for line d awould be:
y = -2
✔️Equation for line e:
Slope (m) = [tex] \frac{rise}{run} = -\frac{3}{4} [/tex]
y-intercept (b) = 1
Substitute m = -¾, and b = 1 in y = mx + b
Equation for line e would be:
✅y = -¾x + 1

Answer:
20
Step-by-step explanation:
Answer: 5 is made up of 5 times 1 of 5 ×4 = 20. A more mathematical way is to actually do this as a division problem of two fractions. 5 = 5 1. so divide 5 1 by 1 4. 5 1 1 4. This is a complex fraction make it simpler by multiplying both sides by the inverse of 1/4 which is 4/1.

What polygon has interior angle measures of 162°?
Answer:
If you are given the measure of each interior angle (162 degrees) of a regular polygon. how many sides does the polygon have? If you look at a pentagon first where the interior angle is 108 deg then you see. The angle at the center is 180-162=18 deg and 360/18=20 so the polygon has 20 sides.
Carissa earns $450 per week for a 40 hour work week plus $16.83 per hour for each hour of overtime after 40 hours. Write an equation that would be used to determine her weekly wages where, W, is her wages and, V, is the number of overtime hours worked.
Answer:
The equation that determines Carissa's weekly wages is W = 450 + 16.83 × V
Step-by-step explanation:
The given parameters are
The amount Carissa earns per week = $450
The amount Carissa earns for each overtime hour = $16.83
Where the given variables are;
W = Her weekly wages
V = The number of overtime hours worked
Therefore, the equation that would be used to determine her weekly wages is given as follows;
W = 450 + 16.83 × V.
