Answer:Two separate linear functions are expressed by the graph and by the equation. Select all that apply.
VThe slope is negative for both functions.
XThe equation has a steeper slope than the line in the graph.
VThe slope of the line in the graph is -2.
XThe graph and the equation express an equivalent function.
Step-by-step explanation: 1 and 3 got it right on e2020 please mark brainliest
Both lines have a negative slope and The slope of the line in the graph is -2
The equation of a straight line is given by:
y = mx + b;
where m is the slope of the line, b is the y intercept, y,x are variables.
Given that a line goes through (-2, 1) and (0, -3), the equation of this line is given by:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-1=\frac{-3-1}{0-(-2)} (x-(-2))\\\\y-1=-2(x+2)\\\\y-1=-2x-4\\\\y=-2x-3[/tex]
Therefore the slope of the line in the graph is -2
The second line is given by:
[tex]y=-\frac{2}{9} x+2[/tex]
This line has a slope of -2/9
a) Both lines have a negative slope
b) The graph has a steeper slope
c) The slope of the line in the graph is -2
d) The graph and equation do not express an equivalent function because they have different equations

Riley earned enough points on his gas card to save 10 cents per gallon on his next gas purchase.If the price per gallon of gas is $2.50. what percent will he be saving per gollon
Answer:
4%
Step-by-step explanation:
4% of $2.50 is 10 cents
Riley can save 4% per gallon as his savings during the purchase of gas.
What is a percentage?"A percentage is a number or ratio expressed as a fraction of 100. It is a relative value indicating hundredth parts of any quantity. It is often denoted using the % percent sign".
For the given situation,
Price per gallon of gas = $2.50
Riley saves price per gallon = 10 cents
We know that, [tex]\$1 = 10 cents[/tex]
⇒ [tex]\$2.50=2.50 (100) cents[/tex]
⇒ [tex]\$2.50=250cents[/tex]
Now 10 cents are how many percent of 250 cents can be determined by
⇒ [tex]\frac{10}{250}(100)[/tex]
⇒ [tex]4\%[/tex]
Hence we can conclude that Riley can save 4% per gallon as his savings during the purchase of gas.

Answer:
A) 5x-7y=42
Step-by-step explanation:
We know that 5 x 7 = 35 then add 7 = 42
We divide 5 and 7 by 5/7
5/ 5/7 = 0.1
7/ 5/7 = 0.2
We find 0.1 = 1/10 and we know that 1/10 of 35 is 3.5
We find 0.2 = 2/10 and we know that 2/10 of 35 is 7 so the answer 7 matches.
We then use 7 for y and keep 5 for x.

Accelerated students: Answer the above and make a line plot of the data.
Answer:
Mean: 88.5
Median:90
Mode:98
Step-by-step explanation:
For mean, what you need to do is add all of those numbers up and divide them by how many you have. So once you add up all those numbers, divide them by six because there are 6 numbers. For the median, order the numbers from smallest to biggest and cross off every one until you get left with the number in the middle. If there is an even number of numbers and there are two middle ones, add them together and divide them by 2. For mode, it’s the one with the most.

Answer:
x = 20
y = 10
Step-by-step explanation:
Since we have a right triangle then:
sin(60) = 10√3/x ⇒ x = 10√(3)÷sin(60) = 20
cos(60) = y/20 ⇒ y = 20×cos(60) = 10
Answer:
Option B)
The value of x is 20 and y is 10
Step-by-step explanation:
Here, in a given right triangle
ΔABC, m∠B = 90°
Now,
tanθ = opposite ÷ adjacent
tan 60° = 10√3 ÷ y
√3 = 10√3 ÷ y
y = 10√3 ÷ √3
y = 10
Now,
sinθ = opposite ÷ hypotenuse
sin 60° = 10√3 ÷ x
√3 ÷ 2 = 10√3 ÷ x
√3 × x = 10√3 × 2
x = 20√3 ÷ √3
x = 20
Thus, The value of x is 20 and y is 10
