Answer:
-21
Step-by-step explanation:
the y intercept is when x=0.
you can see that this is a linear equation where each increase in x results in an increase of 4 onto the y value.
so if when x=1, y=-17, subtract 4 to find what y equals when x is 0.
-17 -4=-21
good luck :)
Answer:
VPQ = 83°
Step-by-step explanation:
You can draw a circle around the point P, and a circle have 360°, so it means that the sum off all the angles have ro be 360°. Some of these angles have the same measure, because they're formed by the same lines segments, they are:
SPR = UPV; TPU = RPQ; TPS = VPQ
360 - SPR - UPV - RPQ - TPU = VPQ + TPS
As some of they are equal, we can just multiply they by 2:
360 - 2×SPR - 2×RPQ = 2× VPQ
360 - 2×35 - 2×62 = 2×VPQ
360 - 70 - 124 = 2×VPQ
2 VPQ = 166
VPQ = 166/2
VPQ = 83°
Answer:
y = (x +4)(x +2)²(x +1)
Step-by-step explanation:
The function has a generally U shape, so is of even degree. The zero where the graph touches, but does not cross, the x-axis is a zero of even multiplicity. The minimum degree of a function that matches this description is 4. It will have zeros at x=-4, -2 (multiplicity 2), and -1. The constants in the corresponding binomial factors will be the opposite of these values, so the factored form is ...
y = (x +4)(x +2)²(x +1)
__
The multiplicity of a zero is the power of the corresponding factor.

Answer:
k=11
Step-by-step explanation:
Slope is calculated by dividing the change in y over the change in x. The change in x for these points is 4. This leaves us with y/4 as the slope, which must equal 2. Divide both sides of the equation (y/4=2) by 4. y=8
Now add 8 to the y coordinate of (1,3) in order to get a y value of 11 for the second coordinate.
