this is the first one I'm not to good with area
Answer:
Im taking this right now so Im not 100% sure
Step-by-step explanation:
y-intercept: 2 because the slope is passing through 2.
slope: take points (-1,2) and (-1,3)
m=Y2-Y1/X2-X1
m=3-2/-1-1
m=-1/2 or 1/-2(there is no difference)
so the slope is -1/2
b=2
in slope intercept, its going to be:y=-1/2x+2
btw, i noticed that the point isn't -1 it's 0.75 i think. Substitute the -1 for -0.75(-3/4) and finish the math. Sorry.
Answer:
x = 40
Step-by-step explanation:
5x + 900 = 1100
=> 5x = 1100 - 900
=> 5x = 200
=> x = 40
Hoped this helped.
Answer:
x=2
Step-by-step explanation:
28−(3x+4)=2(x+6)+x
We need to use the distributive property for the right side.
28−3x−4=(2)(x)+(2)(6)+x)
28−3x−4=2x+2+x
−3x+24=3x+12
From here we need to subtract 3x from both side.
−3x+24−3x=3x+12−3x
6x+24=12
Transfer +24 on the right side.
6x=12−24
6x=−12
Finally, divide both sides by −6
6x/-6 = -12/-6
x=2

Step-by-step explanation:</h3>
Parabolas are graphs that make U-shapes and are formed from quadratic equations.
Vertical Parabolas
There are 2 different types of parabolas: vertical and horizontal.
- Vertical parabolas have a vertical axis of symmetry. So, they open up or down.
- Horizontal parabolas have a horizontal axis of symmetry. So, they open left or right.
If the x-value is squared, then the parabola is vertical. So, this graph must open up or down.
Positive A-Value
The a-value is the coefficient before the squared term. In a vertical parabola, the graph opens up if the a-value is positive. On the other hand, the graph opens down when the a-value is negative.
In this case, the graph is a vertical parabola that opens up. This means that the range will have a minimum value but no maximum.
