Answer:
-2
this eq. can be simplified to -
y = 5 - 2x
we know that the coefficient of x is the slope
therefore , -2 is the slope
Answer:
A. -2
Step-by-step explanation:
Arrange to y-intercept form:
-4x + 7 = 2y - 3
7 = 4x + 2y - 3
7 + 3 = 4x + 2y
10 = 4x + 2y
10 - 2y = 4x
-2y = 4x - 10
y = -2x + 5
As you can see, -2 is the slope of the equation.
Answer: Dimes= 20, Nickels= 15
Step-by-step explanation:
Since we are looking for the amount of coins, we can use system of equations to solve for the amount of coins.
Equation 1:
0.1x+0.05y=2.75
This equation comes from the total cost. x stands for dimes and y stands for nickels. 0.1 is the worth of a dime and 0.05 is the worth of a nickel.
Equation 2:
x=2y-10
This equation comes from 10 less than twice the number of nickels.
We can use substitution to find x and y.
0.1(2y-10)+0.05y=2.75
0.2y-1+0.05y=2.75
0.25y-1=2.75
0.25y=3.75
y=15
There are 15 nickels.
Now that we have y, we can plug it back into the equation to find x.
x=2(15)-10
x=30-10
x=20
There are 20 dimes.

Answer:
(Choice A) A graph of an increasing linear function in quadrant 1 with a positive y-intercept.
Step-by-step explanation:
The weight of the sumo wrestler starts at a positive value of 79.5 kilograms, and we are given that the sumo wrestler gains a linear amount of weight per month at 5.5 kilograms per month.
If we were to graph this relationship, the sumo wrestler's weight would be represented on the y-axis, and the amount of time on the x-axis.
So the initial weight would occur at (0, 79.5) which is the positive y-intercept.
And since his weight is increasing at 5.5 kilograms per month, the slope of the linear function is positive.
Hence, the graph of the linear increasing function in quadrant 1 with a positive y-intercept.
Cheers.
Answer:
59/100
Step-by-step explanation:
2*25+5+4=59
Answer:
C) 35.98
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan theta = opp /adj
tan 17 = 11/x
x tan 17 = 11
x = 11/ tan 17
x =35.9793788
Answer:
Tjhe final answer I came apon was 35.98 for this problem.
"C) 35.98"
Here why :
First of all it is an
so we can use trigonometry. functions
oppration : tan theta = opp /adj
Step 1 tan 17 = 11/x
Step 2 x tan 17 = 11
Step 3 x = 11/ tan 17
Step 4 x =35.98 (when roundened)
Hope this helps
