Step-by-step explanation:
Convert the decimal number to a fraction by placing the decimal number over a power of ten. Since there is
1
number to the right of the decimal point, place the decimal number over
10
1
(
10
)
. Next, add the whole number to the left of the decimal.
1) Triangle T1 is transformed into triangle T2 by
a. dilation with scale factor of 1/2
b. reflection over the y-axis
c. translation
2) and triangle T2 is transformed into trinagle T3 by
a. dilation with scale factor 1/2
b. reflection over the x-adis
c. rotation
Answer:
1) The correct option is;
b. Reflection over the y-axis
2) The correct option is;
a. Dilation by a scale factor of 1/2
Step-by-step explanation:
1) The rule for reflection over the y-axis is given as follows;
Given the point of the preimage before the reflection = (x, y), the point of the image after the reflection will be (-x, y)
The coordinate of a point on T1 is (-2, 4). The coordinate of similar point in T2 is (2, 4) which satisfies the rule for reflection over the y-axis
2) The length of a side in triangle T2 is given by the formula for finding the length, l, of segments between coordinate points as follows;
[tex]l = \sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}[/tex]
Point 1, (x₁, y₁) = (2, 4)
Point 2, (x₂, y₂) = (6, 2)
The length = √((2 - 4)² + (6 - 2)²) = 2·√5
The length of the corresponding side in T3 is given as follows;
Point 1, (x₁, y₁) = (1, 2)
Point 2, (x₂, y₂) = (3, 1)
The length = √((1 - 2)² + (3 - 1)²) = √5
The length of of a side T3 = 1/2 of the length of a side of T2
Therefore. triangle T2 is transformed into triangle T3 by dilation with a scale factor of 1/2.

3(2x-5)=-15
Answer:
x=0
Step-by-step explanation:
Divide both sides by the numeric factor on the left side, then solve.
3(2x−5)=−15
Step 1: Simplify both sides of the equation.
3(2x−5)=−15
(3)(2x)+(3)(−5)=−15(Distribute)
6x+−15=−15
6x−15=−15
Step 2: Add 15 to both sides.
6x−15+15=−15+15
6x=0
Step 3: Divide both sides by 6.
6x/6 = 0/6
x=0

this line? 10. A line passes through the points (-3, -1) and (-5, 4). What is the slope of this line?
Answer:
-4/7
Step-by-step explanation:
To calculate slope, you should put your points into this form - (y1-y2)/(x1-x2). In this case, it's (-5+1)/(4+3).

If water flows through a pipe at a rate of 6 milliliters per hour, how wil I express this rate of flow in pints per day?
Answer:
0.304 pints per day
Step-by-step explanation:
Here, we want convert
if 6 milliliters flow in an hour , then in a day which is 24 hours, the amount that will flow is 24 * 6 = 144 milliliters in a day
so we need to convert this to pint
mathematically;
1 pints= 473.176 ml
x pints = 144 ml
x =
144/473.16 = 0.304 pints per day

Write an equation in slope-intercept form of the line that passes through (3,8) and (1,-2)
Step-by-step explanation:
let eqn be y = mx + b.
m = (-2 - 8)/(1 - 3) = 5
sub (3, 8):
8 = 5(3) + b
b = -7
therefore equation of the line is y = 5x - 7

The total number of miles, d, Elise walks in n hours can be modeled by the equation d = ns. Her rate stays the same each hour. Which represents the number of miles Elise walks per hour?
Answer:
Step-by-step explanation:
Given the number of miles Elise walks in n hiurs modeled by the equation;
d = ns
The number of miles he walks per hour is expressed by substituting n =1 into the equation to have;
d = ns
d = (1)s
d = s
Hence the number of miles he walked per hour is expressed as d = s
