Find the x- and y-intercepts of the graph of the linear equation 2x+3y=12.
Answer:
x-intercept= 6
y-intercept= 4
Step-by-step explanation:
Solve for x first then solve for y.
Answer: y= -2/3x+4
The X-Intercept is -2/3
The Y- Intercept is 4
Hope this helps!! Have a wonder day everyone!! (:
Step-by-step explanation:
Step one write out the equation 2x+3y=12
Then move the variable to the right hand side and change the sign. 3y=12-2x
Then divide both sides of the equation by 3. You get y=4-2/3x
Then: Use the Commentative Property to reorder the terms. y= -2/3x+4

Answer:
1/5
Step-by-step explanation:
pick any points, for example (6, -1) and (11, 0)
slope is m= (y2-y1) / (x2-x1) = -1-0 / 6-11 = -1 / -5 = 1/5

Should be pretty easy to answer, I just need a refresher. I forgot how to solve for triangles...

Step-by-step explanation:
Trigonometric Ratios
The ratios of the sides of a right triangle are called trigonometric ratios. There are six trigonometric ratios, sine, cosine, tangent, cosecant, secant, and cotangent.
The longest side of the triangle is called the hypotenuse and the other two sides are the legs.
Selecting any of the acute angles as a reference, it has an adjacent side and an opposite side. The trigonometric ratios are defined upon those sides.
Note we are given an angle of 25°. The opposite side is 12 and the adjacent side is x. We need to relate those sides with a trig function (the tangent ratio)
Tangent Ratio:
[tex]\displaystyle \tan\theta=\frac{\text{opposite leg}}{\text{adjacent leg}}[/tex]
Substituting:
[tex]\displaystyle \tan 25^\circ=\frac{12}{x}[/tex]
Solving for x:
[tex]\displaystyle x=\frac{12}{\tan 25^\circ}[/tex]
Calculating:
[tex]\displaystyle x=\frac{12}{0.466307}[/tex]
x = 25.734083
Round to 3 decimals:
[tex]\mathbf{x \approx 25.734}[/tex]

A number p is less than 6 and greater than 2. What’s the inequality?
Answer: 2<p<6
Step-by-step explanation:
p < 6
p > 2
if we were to flip that second one, p > 2, we get 2 < p.
now we combine that with the other inequality.
2 < p < 6
determine the slope of the table
Answer:
The slope is -1/2 or -0.5

C) y = -x
D) y = -x +
4
Answer:
1. C 2.D 3.D 4.A
Step-by-step explanation:
The first one would be C because the slope is -1, which can also be -x and the y-intercept is 0, meaning you don't need to add or subtract anything.
The second one is D because the slope is -3, meaning it's -3x, and the y-intercept is positive, meaning you add 5.
The third one is D because the slope is 5/4, which is 5/4x and the y-intercept is positive 3, meaning you add 3.
And the fourth one is A because there is no slope, so y would just equal 3.
Please what’s the answer to this ?
Answer:
x=-10
Step-by-step explanation:
so a triangle is 180 degrees
look at this all sides are congruent so all angles are 60
60*3=180
now solve for x
x+70=60
x=-10
what is the value of x in this triangle
Answer:
30
Step-by-step explanation:
if the total angles in a triangle equals 180, and there is 6x in total (after adding it up), 180 divided by 6 equals 30.
Hope that makes sense!

Answer:
8
Step-by-step explanation:
You always start with the equasions in parenthesis. 3-1 is 2 and 8 divided by 2 is 4. Then you can move on to the next part of the eqasion. You start by subtracting 2 from 5 and then multiplying that by 2.then you add up the answers and you gat 8.
Last year at a certain high school, there were 96 boys on the honor roll and 60 girls on the honor roll. This year, the number of boys on the honor roll increased by 25% and the number of girls on the honor roll increased by 10%. By what percentage did the total number of students on the honor roll increase? Round your answer to the nearest tenth (if necessary).
Answer:
19%
Step-by-step explanation:
Last year:
Number of boys on honor roll = 96
Number of girls on honor roll = 60
Total students on honor roll = Number of boys on honor roll + Number of girls on honor roll
= 96 + 60
= 156
This year:
The number of boys on the honor roll increased by 25%
Number of boys on honor roll = 25% of 96 + 96
= 0.25×96 + 96
= 24 + 96
= 120
The number of girls on the honor roll increased by 10%.
Number of girls on honor roll = 10% of 60 + 60
= 0.10 × 60 + 60
= 6 + 60
= 66
Total students on honor roll = Number of boys on honor roll + Number of girls on honor roll
= 120 + 66
= 186
Percentage the total number of students on the honor roll increase = (186 - 156) / 156 × 100
= 30 / 156 × 100
= 0.19 × 100
= 19% to the nearest tenth

Which coordinate pair is a solution to the inequality 4x - 2y <22
Step-by-step explanation:
Given the inequality 4x - 2y < 22, to get the ordered pair of the inequality, we will have to set x = 0 and y = 0 and then solve
when x = 0;
4(0)-2y < 22
-2y < 22
Divide both sides by -2
-2y/-2 > 22/-2
y > -11
When y = 0
4x - 2(0)<22
4x < 22
x < 22/4
x < 11/2

In the isosceles trapezoid, m∠S=68∘ .
What is m∠Q ?
9514 1404 393
Answer:
112°
Step-by-step explanation:
Same-side angles of a trapezoid are supplementary.
m∠P = 180° - m∠S = 180° -68° = 112°
The angles of an isosceles trapezoid match their symmetrical counterparts.
m∠Q = m∠P
m∠Q = 112°
