Question 6 of 10
Which of the following graphs represents the equation y- 4 = 3(x - 1)?
Answers
Graph D
Step-by-step explanation:
The following equation: y - 4 = 3 (x - 1) is written in Point-Slope Form.
In Slope-Intercept Form, it would look like this: y = mx + b where m = slope and b = y-intercept.
*****************************************************Point-Slope Form: y - y1 = m (x - x1)
Slope-Intercept Form: y = mx + b
*****************************************************
To graph the equation we’ll need it to be in Slope-Intercept Form.
y-intercept = 1 because when x reaches 0, y = 1
The first two points are: (0, 1) (1, 4) as we can see that from (1, 4) to (0, 1) or (0, 1) to (1, 4), the slope is 3
Therefore, the Slope-intercept form: y = 3x + 1
The graph that best represents the following equation is Graph D because it contains the point (1, 4)

Answer:
x is 7 and m<1 is 99°
Step-by-step explanation:
m<NMQ + m<MQN + m<QNM = 180°
[tex]{ \sf{(5x + 19) + (8x - 11) + (11x + 4) = 180}} \\ { \sf{24x + 12 = 180}} \\ { \sf{24x = 168}} \\ { \sf{x = \frac{168}{24} }} \\ \\ { \sf{x = 7}}[/tex]
m<1 = 180° - (11x + 4)
m<1 = 180° - 81°
m<1 = 99°
Using angle sum property
[tex]\\ \sf\longmapsto 5x+19+8x-11+11x+4=180[/tex]
[tex]\\ \sf\longmapsto 24x12=180[/tex]

The backyard of a new home is shaped like a trapezoid with a height of 44 ft and bases of 90 ft and 110 ft. What is the cost of putting sod on the yard, if the
landscaper charges $0.25 per square foot for sod?
Answers
Answer:
$1100
Step-by-step explanation:
First find the area of the trapezoid
A = 1/2 (b1+b2)*h
A = 1/2 ( 90+110) *44
A = 1/2(200)*44
A = 4400ft^2
The cost is .25 per square foot
4400* .25 =1100
Answer:
$1100
Step-by-step explanation:
((90 + 110)/2 * 44)) * .25 = 1100

X
96°
x =
degrees
Answers
Answer:
x=144°
Step-by-step explanation:
To work out x, you have to find the other angle in the triangle.
Angles in triangles always add up to 180°, so you would have to add up the 2 angles you have and take it away from 180°.
48+96=144°
180-144=36°
Then, to find x, you have to do 180-36 because angles on a straight line always add up to 180°.
180-36=144°
x=144°
Hope this helps :)
An exterior angle of a triangle is equal to the sum of its interior opposite angles.

Which graph represents the given equation?
y

NICO
+ 4r – 2
Answers
Equations can be represented on graphs by plotting the corresponding x and y values. The graph of [tex]y = \frac{3}{2}x^2 + 4x - 2[/tex] is option (B).
Given that:
[tex]y = \frac{3}{2}x^2 + 4x - 2[/tex]
First, we check the y intercept of [tex]y = \frac{3}{2}x^2 + 4x - 2[/tex]
This is when [tex]x = 0[/tex]
So, we have:
[tex]y = \frac{3}{2}x^2 + 4x - 2[/tex]
[tex]y = \frac{3}{2} \times 0^2 + 4\times 0 - 2[/tex]
[tex]y = - 2[/tex]
This point is represented as: [tex](0,-2)[/tex]
Next, check the equation when [tex]x = 1[/tex]
So, we have:
[tex]y = \frac{3}{2}x^2 + 4x - 2[/tex]
[tex]y = \frac{3}{2} \times 1^2 + 4\times 1 - 2[/tex]
[tex]y = 3.5[/tex]
This point is represented as: [tex](1,3.5)[/tex]
From the list of given options (see attachment).
Only graph B has the [tex](0,-2)[/tex] and [tex](1,3.5)[/tex] on its curve.
Hence, option (B) is correct.
