Answer:
The intercepts of a graph are points at which the graph crosses the axes. The x-intercept is the point at which the graph crosses the x-axis. At this point, the y-coordinate is zero. The y-intercept is the point at which the graph crosses the y-axis. At this point, the x-coordinate is zero.
To determine the x-intercept, we set y equal to zero and solve for x. Similarly, to determine the y-intercept, we set x equal to zero and solve for y. For example, lets find the intercepts of the equation \displaystyle y=3x - 1y=3x−1.
To find the x-intercept, set \displaystyle y=0y=0.

HOW TO: GIVEN AN EQUATION, FIND THE INTERCEPTS.
Find the x-intercept by setting \displaystyle y=0y=0 and solving for \displaystyle xx.
Find the y-intercept by setting \displaystyle x=0x=0 and solving for \displaystyle yy.

[tex]\sin N = 0.80[/tex]
Step-by-step explanation:
Given
See attachment
From the attachment, we have:
[tex]MN = 6[/tex]
[tex]LN = 10[/tex]
First, we need to calculate length LM,
Using Pythagoras theorem:
[tex]LN^2 = MN^2 + LM^2[/tex]
[tex]10^2 = 6^2 + LM^2[/tex]
[tex]100 = 36 + LM^2[/tex]
Collect Like Terms
[tex]LM^2 = 100 - 36[/tex]
[tex]LM^2 = 64[/tex]
[tex]LM = 8[/tex]
Solving (a): [tex]\sin L[/tex]
[tex]\sin L = \frac{Opposite}{Hypotenuse}[/tex]
[tex]\sin L = \frac{MN}{LN}[/tex]
Substitute values for MN and LN
[tex]\sin L = \frac{6}{10}[/tex]
[tex]\sin L = 0.60[/tex]
Solving (b): [tex]tan\ N[/tex]
[tex]tan\ N = \frac{Opposite}{Adjacent}[/tex]
[tex]tan\ N = \frac{LM}{MN}[/tex]
Substitute values for LM and MN
[tex]tan\ N = \frac{8}{6}[/tex]
[tex]tan\ N = 1.33[/tex]
Solving (c): [tex]\cos L[/tex]
[tex]\cos L = \frac{Adjacent}{Hypotenuse}[/tex]
[tex]\cos L = \frac{LM}{LN}[/tex]
Substitute values for LN and LM
[tex]\cos L = \frac{8}{10}[/tex]
[tex]\cos L = 0.80[/tex]
Solving (d): [tex]\sin N[/tex]
[tex]\sin N = \frac{Opposite}{Hypotenuse}[/tex]
[tex]\sin N = \frac{LM}{LN}[/tex]
Substitute values for LM and LN
[tex]\sin N = \frac{8}{10}[/tex]
[tex]\sin N = 0.80[/tex]

Last week, Clay had a beginning balance of $50 in his account. He wrote 2 checks for $23 each from his checking account , withdrew another $5, and finally made a deposit of $22. Part A: Write an expression and your answer to show his final account balance at the end of the week 23 * 2 = 46 Part B: Explain in words, what Clay should do to get his accaunt balance to zero?
Answer:
Part A
y =($50 - ($23 × 2 + $5)+ $22)
y = $21
Part B
Clay can get his balance to zero by withdrawing or writing another check for $21
Step-by-step explanation:
Last week, Clay had a beginning balance of $50 in his account. He wrote 2 checks for $23 each from his checking account , withdrew another $5, and finally made a deposit of $22.
Part A: Write an expression and your answer to show his final account balance at the end of the week 23 * 2 = 46
Let his final Account Balance = y
y =($50 - ($23 × 2 + $5)+ $22)
y =$72 - $51
y = $21
Part B: Explain in words, what Clay should do to get his account balance to zero?
Clay can get his balance to zero by withdrawing or writing another check for $21
= $21 - $21
= $0

Answer:
[tex]x=\frac{5d+6ba}{6b+7g}[/tex]Step-by-step explanation:
Answer:
x = (3a²b + 5d) / (6b + 7g)Step-by-step explanation:
Given:
3b( 2x − a² ) = 5d − 7gxSolving for x:
6bx - 3a²b = 5d - 7gx6bx + 7gx = 3a²b + 5d(6b + 7g)x = 3a²b + 5dx = (3a²b + 5d) / (6b + 7g)Graph the solution of this inequality:
350 > 125 + 150
10 20 30 40 50 60 70 80 90 100 110 120
Drag a point to the numb
Step-by-step explanation:
The given inequality is :
[tex]350\ge 125+15x[/tex] ....(1)
We need to draw graph of this inequality.
Subtract 125 from both sides.
[tex]350-125\ge 125-125+15x\\\\225\ge 15x[/tex]
Dividing 15 to both sides.
[tex]\dfrac{225}{15}\ge \dfrac{15x}{15}\\\\15\ge x[/tex]
Hence, the attached figure shows the graph for this inequality.

Amelia's Reliable Fencing Co. prices fences based on the amount of fencing installed plus a fixed amount of $200. The
company charges S4 per foot of standard fencing. Which of the following scenarios is correct?
It costs $1040 to enclose a 90' by 40' rectangular area.
It costs $560 to enclose a 50' by 40' rectangular area.
ОООО
It costs $2600 to enclose a 10' by 60' rectangular area.
It costs $1480 to enclose an 80' by 80' rectangular area.
Answer:
It costs $560 to enclose a 50' by 40' rectangular area.
Step-by-step explanation:
50 + 40 = 90
90 x 4 = 360 because of the $4 per foot
360 + 200 = 560, you add 200 because of the flat rate charge.

Noah orders an extra-large pizza. It costs $12.49 for the pizza plus $1.50 for each topping. He orders an extra-large pizza with toppings that costs a total of dollars. Select all of the equations representing the relationship between the number of toppings and the pizza's total cost with toppings.
a. 12.49 + t = d
b.12.49 + 1.50d = d
c. 12.49 + 1.50 = t
d. 12.49 = d +1.50t
e. t = [tex]\frac{d-12.49}{1.5}[/tex]
f. t = d - [tex]\frac{12.49}{1.5}[/tex]
The equation to represent the given situation is 12.49+1.50d=t. Therefore, options B and E are the correct answers.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Given that, Noah orders an extra-large pizza. It costs $12.49 for the pizza plus $1.50 for each topping.
Let t be total money and d be the number of toppings.
So, the equation is 12.49+1.50d=t
1.50d=t-12.49
d=(t-12.49)/1.50
Therefore, options B and E are the correct answers.

Answer:
slope:5/2
y-intercept:-9
Step-by-step explanation:
Answer:
2.5
Step-by-step explanation:
First, we need to change the equation into slope-intercept form.
5x-2y=18 Isolate the y by subtracting 5x on both sides.
-5x -5x
-2y=-5x+18 Divide both sides by -2.
/-2 /-2
y=2.5x-9
The slope is the number next to x, so the slope is 2.5.
